Is Your CBD Product Verifiably Natural?

By Jordan Turner
No Comments

Natural product analysis using Carbon-14 is a valuable scientific tool that can be used to confirm the naturality of cannabidiol-based (CBD) ingredients by verifying the percentage of a product that is obtained from naturally-sourced ingredients. Determining the percentage of biobased content in a product allows companies to ensure their CBD ingredients are truly natural-derived, identify the presence of synthetic adulterants, and authenticate marketing and “natural” labeling claims.

Why consider natural product analysis using Carbon-14 to validate your natural CBD products?

Carbon-14 is an isotope present in naturally-sourced materials. Natural product analysis measures the percentage of Carbon-14 present in an ingredient or product. Higher percentages indicate that a product is primarily or completely made with natural-sourced ingredients as opposed to synthetic, petroleum-derived alternatives. These cheaper, synthetic alternatives created from petroleum-based sources cannot be measured using Carbon-14. A product that is all-natural and completely plant-sourced will show a result of 100% biobased content whereas a low or zero percentage will reveal a product that is partially or completely formulated with synthetic adulterants.

The structure of cannabidiol (CBD), one of 400 active compounds found in cannabis.

Why should you be concerned with verifying the naturality of your CBD products? In recent years, the popularization of CBD extract has increased its demand as an ingredient in personal care and cosmetic products. Higher costs associated with the use of natural CBD extract instead of artificial extracts leads to the use of adulterated ingredients by some manufacturers or false label claims that a product is natural when it is not.

How can you prove your products are the real deal and ensure your customers are sure they’re getting the natural ingredients they expect? Artificial ingredients derived from petrochemical sources do not contain any carbon-14 content. The results of natural product analysis reveal the percentage of a sample that is procured from natural sources, allowing manufacturers and quality assurance teams to confirm their CBD ingredients and products are not synthetic or adulterated and to strengthen claims that their product is truly natural-derived.

Natural product analysis can authenticate the natural content of your CBD products. Validating naturality with Carbon-14 testing strengthens label and marketing claims and confirms your products and ingredients are completely natural and do not contain cheap synthetic adulterants. By verifying the percentage of our product that comes from natural sources as opposed to artificial, petrochemical sources, you can guarantee your product is genuinely made with natural CBD extract.

Recent Developments in Supercritical CO₂ Winterization

By Aaron Green
No Comments

Supercritical carbon dioxide (CO2) extraction is a processing technique whereby CO2 is pressurized under carefully controlled temperatures to enable extraction of terpenes, cannabinoids and other plant molecules. Once the extract is obtained the crude is often subjected to an ethanol winterization process to remove chlorophyll, fats and waxes.

Green Mill Supercritical is a Pittsburgh-based manufacturing and engineering company focused on cannabis and hemp extraction. The company offers a range of CO2 extraction equipment where users can tune and control their extraction methods. They recently announced  a technology advance enabling winterization in-process, which has the potential to remove the need for ethanol winterization.

We spoke with Jeff Diehl, director of marketing at Green Mill Supercritical, to learn more about the new process. Jeff was working in the tech industry in San Francisco in 2017 when he was invited to join Green Mill by his cousin, Jeremy Diehl, who is the founder and CTO.

Aaron Green: Before we get to your new technology, can you explain what industry trends you are watching?

Jeff Diehl: A big thing that I watch is the premium extract space. More and more consumers are demanding higher premium extracts. They want differentiated products. They want products that are safe and that have some kind of meaningful connection to the specific plant from which they came. Right now, CO2 plays a small role in the market for those products. Most premium products are generated through hydrocarbon extraction. So, I am watching how people are using CO2 to create the next generation of safe, premium products.

Aaron: What is the normal process for a CO2 extraction today?

Jeff Diehl, director of marketing at Green Mill Supercritical

Jeff: The current CO2 extraction process generally consists of two major phases to producing your final extract. In the first phase, you have extraction where you get your crude product. The second phase is post-extraction where you do cleanup to get your refined oil. Within that post-extraction phase, most operations include an ethanol-based winterization process.

Aaron: What does the winterization step do, exactly?

Jeff: Winterization is about removing waxes. Your main extraction is considered crude because it’s got a lot of materials from the plant that you don’t want. The large majority of unwanted material is waxes. Winterization is the process of using a solvent, traditionally ethanol, to separate the waxes from the cannabinoids. There are multiple challenges inherent in ethanol-based winterization that introduce cost, time and product loss. It’s terribly inefficient. Plus, there will always be residual ethanol left in your final product, and that’s not something consumers appreciate.

Aaron: You’ve recently announced a new process at Green Mill that moves the winterization step into the supercritical CO2 equipment. Can you explain how that works?

Jeff: With our process, which we call Real-Time Winterization, there is no ethanol involved in winterization anymore. It is all done with CO₂ during the primary extraction. That’s the major advance of our process and although it has been attempted before, no one has succeeded at doing it in a viable way. You take a process which is normally four days – one day for CO2 extraction and three days for ethanol winterization – and you do it all in less than a day. We have automated software, sensors and pumps that makes this all possible.

Aaron: How does the quality of the resulting product compare with the new process?

Jeff: You can see the difference right away, if you’re at all familiar with extraction. It just looks clean and bright. Lab analysis has been very positive thus far, but we continue to run tests. Our R&D team has done multiple tests, mostly on hemp and CBD. That’s because we don’t have a license for THC. We’re currently engaging with a licensed partner so that we can collect more data on THC-containing products, so we can give exact numbers. But with CBD, we’ve done multiple tests to validate the method and the technology, and are seeing consistently excellent results in regards to both purity of the product and efficiency of the process.

Aaron: How do yields compare between the processes?

Hemp CBD extract straight out of a Green Mill SFE Pro running Real-Time Winterization.

Jeff: From the data that we’ve seen in the industry, it looks like when you winterize with ethanol, you leave anywhere from 5 to 10% of your cannabinoids behind in the waxes. That’s just lost. With Real-Time Winterization using CO2 we have seen recovery rates as high as 99%. We are continuing to investigate that result with testing to make sure it was not an outlier, but in any case, recovery rates look promising.

Aaron: One of the other issues with ethanol is taxes and the ability to find food grade supply. Do you have any perspective you can share on that?

Jeff: There are a number of advantages to moving away from ethanol. The sheer quantity of ethanol is a factor. There are a lot of regulations and fire requirements around managing large quantities of ethanol. The ethanol winterization process itself is not just one process. There are multiple stages, from mixing, to freezing, to filtering, to removing the solvent. These are all opportunities for things to go wrong, so you’re always managing those risks. Multiple large pieces of equipment, including fume hoods, filter skids, cryo freezers and rotary evaporators, are expensive and require heavy management.

I think Elon Musk said the best process is no process. Anytime in an industrial process when you can remove steps in the process, that’s the direction you want to go in. And, that’s what we’ve done. With this recent work, we have effectively removed post processing for certain categories of end product.

Aaron: Do you have any patents on the new process?

Jeff: We have a patent pending on both the method and the equipment, which is allowing us to talk about this as much as we are.

Aaron: So, how does this work if somebody already owns an existing piece of Green Mill equipment? Is this something that can be retrofitted? Is it a software upgrade?

Jeff: There are two components. One is an equipment upgrade, which can be done retroactively for existing customers, and one is a methodology upgrade, which we assist our customers with. The automation software inherently can handle the settings that you need to run the methodology. In fact, it’s that software and the rest of our existing tech stack, the proprietary pump, the triple inline fractionation, the precision and stability of the overall system, that is what made this winterization advance possible.

Aaron: Where are you rolling this out first? And do you plan to go international?

Jeff: International is definitely in the plan, since we’ve already sold systems abroad. We are currently getting ready to announce the opening of our beta program with the new technology. So, we’re not ready to sell this widely at this time, but we are taking submissions from companies that want to get in early and join us at the forefront of CO₂ extraction innovation.

Aaron: Okay, great. Thanks Jeff, that’s the end of the interview.

Wyoming Lawmakers Introduce Bill to Legalize Cannabis

By Cannabis Industry Journal Staff
No Comments

Update: The House Judiciary Committee has passed the legalization bill, HB0209, by a 6-3 vote. After moving out of the Judiciary Committee, the bill now awaits a floor hearing, which is expected to come within the next week or two during the legislative session that ends on April 2. 

A bipartisan group of lawmakers in Wyoming have introduced a bill to legalize cannabis in the state’s legislature. First reported by Buckrail.com, HB0209 was assigned on March 2. The bill would legalize possession, home grow and sales for adults, as well as establish a regulatory framework for licensing, tracking and taxation.

In November 2020, voters in Montana and South Dakota passed ballot measures that legalize adult use and sales of cannabis. About a month after Election Day, the University of Wyoming conducted a poll that found roughly 54% of Wyoming residents now support legal adult use cannabis. In 2018, UW found that 85% of Wyoming residents support medical cannabis legalization.

In March of 2019, Wyoming Governor Mark Gordon signed a bill into law that essentially legalized hemp in the state. That bill was a boon for the state’s agricultural economy, giving many farmers a much-needed boost in their crop diversity.

Wyoming Governor Mark Gordon

You can find the current version of HB0209 here. Sponsors of the bill include: Representatives Jared Olsen (R-Laramie), Mark Baker (R-Sweetwater) Eric Barlow (R-Campbell/Converse), Landon Brown (R-Laramie), Marshall Burt (L-Sweetwater), Cathy Connolly (D-Albany), Karlee Provenza (D-Albany), John Romero-Martinez (R-Laramie), Pat Sweeney (R-Natrona), Cyrus Western (R-Sheridan), Mike Yin (R-Teton) and Dan Zwonitzer (R-Laramie) and Senators Cale Case (R-Fremont) and Chris Rothfuss (D-Albany).

According to Buckrail, if the bill becomes law, Wyoming could get roughly $49.15 million in tax and license fee revenue in 2022. That number would mean a sizable windfall for the state that saw an 8.5% decline in tax revenue in 2020. Governor Gordon proposed budget cuts as high as 15% for agencies across the state last year. Most of the revenue generated from cannabis taxes would be earmarked for education.

Wyoming’s tax revenue is notoriously limited when it comes to diversity: the state makes its money on oil and gas, and that’s about it. Earlier this year, the Biden administration halted oil and gas leasing on federal land, hitting pause on a nearly half-million-acre deal. If the pause on oil and gas leasing on federal lands continues or were to become permanent, Wyoming stands to lose tens, if not hundreds, of millions of dollars every year.

So, what does the least populous state in the country do when they can no longer generate revenue from oil and gas? Simple. Legalize cannabis.

Navigating Compliance: Practical Application of Fit-For-Purpose

By Darwin Millard
No Comments

What is “fit-for-purpose?” Fit-for-purpose is an established best practice used in several major industries, like information technology, pharmaceuticals, agriculture and inventory management. It is a concept that aligns infrastructure and systems specifications with desired outputs – be that product, service or bottom line. When applied to a cannabis plant, its parts, products and associated processes, it can streamline regulatory framework development, implementation and compliance.

Fit-for-purpose is simply a series of logic questions you ask yourself to determine what business practices you should implement and the regulatory framework in which you must comply. What are you making? Who is it for? Where will it be sold? All this impacts how you would cultivate, process, handle and store a cannabis plant, its parts and products regardless of the type of cannabis plant. The fit-for-purpose concept is a tool that can be applied to any scenario within the cannabis/hemp marketplace. Take for instance, sustainability: a practical example would be to design cultivation standards that are “fit-for-purpose” to the climatic region in which the plants are grown – allowing any type of cannabis plant grown anywhere in the world to meet specifications regardless of the method of production.

There is no “special sauce” here. All fit-for-purpose does is get you to ask yourself: “Are the protocols I am considering implementing ‘fit/appropriate’ to my situation, and if not, which protocols are more ‘fit/appropriate’ based on the products I am making, the target consumer and marketplace in which the products are to be sold?”“Fit-for-purpose is a powerful concept that can be used for simplifying regulatory framework development, implementation and compliance”

A non-cannabis/hemp example of fit-for-purpose could be a scenario where a banana producer wants to implement a data management system into their cultivation practices to better track production and yields. There are many data management systems this banana producer could implement. They could implement a data management system like that of big pharma with multiple levels of redundancy and access control related to intellectual property and other sensitive data. They could also implement a data management system used for tracking warehouse inventory; it cannot exactly capture everything they need but it is better than nothing. Neither example is really “fit/appropriate” to the banana producer’s needs. They need something in between, something that allows them to track the type of products they produce and the data they want to see in a way that is right for them. This idea is at the core of the fit-for-purpose concept.

Applying Fit-for-Purpose

So how do we apply fit-for-purpose to the cannabis/hemp marketplace? Fit-for-purpose reduces the conversation down to two questions: What products are you planning to make and how do those products affect your business practices, whether that be cultivation, processing, manufacturing or compliance. The point being the products you plan to produce determine the regulations you need to follow and the standards you need to implement.

Growers can use it to guide cultivation, harvesting, handling and storage practices. Processors and product manufacturers can use it to guide their production, handling, packing and holding practices. Lawmakers can use it to guide the development, implementation and enforcement of commonsense regulations. This is the beauty and simplicity of fit-for-purpose, it can be applied to any situation and related to any type of product.

Growers can use fit-for-purpose to guide most aspects of their operation

Let us look at some practical examples of fit-for-purpose for cultivators and processors. Cultivators have three main areas of focus, growing, harvesting and storage, whereas processors and product manufacturers have it a little more complicated.

Cultivation of a Cannabis Plant

Growing

Requirements for growing a cannabis plant, including those that can be classified as “hemp”, should be dictated by the product with the strictest quality and safety specifications. For example, growing for smokable fruiting tops (i.e. the flowers) may require different cultivation techniques than other products. You may not want to apply the same pesticides or growth additives to a cannabis plant grown for smokable fruiting tops as you would to a cannabis plant grown for seed and fiber.

Harvesting

The next point is important – harvesting and handling requirements should be agricultural, period. Except for those products intended to be combusted or vaporized and then inhaled. Following our previous example, smokable fruiting tops may require different harvesting techniques than other products, especially if you are trying to maintain the aesthetic quality of these goods. You may choose a different harvesting technique to collect these fruiting tops than you would if primarily harvesting the seed and fiber and thinking of the leftover biomass as secondary.

Storage

When considering the products and their storage, you need to consider each one’s quality and safety specifications. One product may have a temperature specification, whereas another may have a humidity specification. You need to make sure that you store each product according to their individual quality and safety specifications. Then consider the products with the highest risks of diversion and potentially if you need to implement any extra protocols. Continuing our example – smokable fruiting tops, whether classifiable as “hemp” or not, pose a higher risk of theft than seeds or fiber and may require additional security measures depending on the authority having jurisdiction.

Processing and Manufacturing Operations

When applying fit-for-purpose to processing and manufacturing operations, first you must choose the products you want to make and specify the intended use for each product. This allows you to identify the quality and safety requirements and the potential for diversion for each good. Which in turn allows you to specify your manufacturing, processing and handling protocols for each product related to their quality and safety requirements. Then those specific products with higher risks of diversion requiring extra protocols to be put into place depending on local regulations and/or internal risk assessments, should be considered and your practices modified, as necessary.

Commonsense Regulations

Image if regulations governing a cannabis plant, its parts, products and associated processes were based on the intended use rather than a set of attributes that vary from jurisdiction to jurisdiction. It is complicated enough for regulators to think about a cannabis plant or cannabis product without having to worry about if that cannabis plant or cannabis product can be classified as “marijuana” or “hemp.” Fit-for-purpose removes this complication and simplifies the debate.

Using a fit-for-purpose approach eliminates the need to think about the molecular constituents and focuses the conversation on the intended use rather than one or two specific molecules – in this case, d9-THC, the boogie-man cannabinoid. Considering the intended use promotes consumer and environmental health and safety by allowing operators and regulators to focus on what is most important – quality and safety instead of whether something is “marijuana” or “hemp.”

This idea is what drives the real impact of fit-for-purpose. It creates a path forward to a one plant solution. We have where we are now – with “marijuana” and “hemp” – and where we want to get to – cannabis. It is all one plant with many different applications that can be used to create different commercial products. Fit-for-purpose helps bridge the gap between where we are now and where we want to get to and allows us to start thinking about “marijuana” and “hemp” in the same manner – the intended use.

Fit-for-purpose is a powerful concept that can be used for simplifying regulatory framework development, implementation and compliance. Regulations imposed on a cannabis plant, its parts and products should be appropriate to their intended use, i.e. “fit-for-purpose.” This approach challenges the confines of the current draconian bifurcation of the cannabis plant while working within this system to push the boundaries. It creates a path forward to a one plant solution and begs the question: Is the world ready for this novel concept?

GMPs & Cannabis Manufacturing

By Kathleen May

Editor’s Note: While CIJ typically omits the word “marijuana” where possible due to antiquated nomenclature and prejudicial connotations, we understand the legal distinction between cannabis containing THC and hemp requires the use of the word when referencing federal government policies and legislative language.


Despite the rapid evolution of the cannabis industry, the assurance of safe manufacturing practices remains unclear.Both the Food and Drug Administration (FDA) and the Drug Enforcement Administration (DEA) have imposed significant hurdles for cannabis operators to remain on the “right side of the law.” Therefore, manufacturers of both hemp and marijuana products have been left to figure things out on their own, or choose to ignore existing guidance because the lack of federal oversight allows them to do so. Inconsistent regulation on manufacturing, packaging, labeling and testing of cannabis products offers the potential for unsubstantiated, non-scientific and often times blatantly false claims on product safety and efficacy.

Science vs. Law

Hemp and marijuana are both species of the Cannabis family, Cannabaceae. Genetically they are identical but are arbitrarily defined by the presence of delta-9 tetrahydrocannabinol (THC). While science does not differentiate between hemp and marijuana, the law does.

The hemp industry declared a small victory with the passing of the Agricultural Act of 2014 (2014 Farm Bill). Under this bill universities and state agriculture departments were allowed to grow hemp under state law. Additionally, “industrial hemp” was officially defined by establishing the legal limit of THC at 0.3% on a dry weight basis. The Agricultural Improvement Act of 2018 (2018 Farm Bill), under the guidance of the United States Department of Agriculture (USDA), took things a few steps further by authorizing the cultivation of hemp and removed hemp and hemp seeds from the CSA. The bill however provides no language that mandates the safe manufacture of hemp-derived consumer goods. The 2018 version also preserved the FDA’s authority to regulate products containing cannabis and cannabis-derived compounds under the Federal Food, Drug, and Cosmetic Act (FD&C Act). To the surprise of most, listing cannabidiol (CBD), even hemp-derived, as an ingredient on consumer product labels remains illegal under the bill. Furthermore, CBD product manufacturers are not protected under the current regulations. Since 2015 the FDA has issued warning letters to firms marketing CBD products as dietary supplements and/or foods, and in December 2018, FDA declared it illegal to introduce food containing CBD (or THC) into interstate commerce, regardless if it is derived from hemp. To date, the only FDA approved CBD product is GW Pharmaceutical’s Epidiolex.

Marijuana remains classified as a Schedule I controlled substance under the CSA. Thirty-six (36) states have approved comprehensive, publicly available medical marijuana programs, and now 14 states have approved adult use programs, with New Jersey passing legislation on February 22, 2021. However, the industry has seen minimal movement toward mandating GMP requirements in the marijuana market. Only a handful of medical programs require manufacturers to follow GMP. Furthermore, the requirements are inconsistent between states and the language in the regulations on how to approach GMP implementation is vague and disjointed. This fragmented guidance supports the complexity and difficulty of enforcing a coherent, standardized and reliable approach to safe manufacturing practices.

What is GMP and Why Should You Care?

Good Manufacturing Practices (GMPs) are a system for ensuring that products are consistently manufactured and controlled according to quality standards and regulatory guidelines. The implementation of a GMP compliant program ensures consumer health and safety, allows manufacturers to understand the intended use of their products, allows manufacturers to defend product specifications as being appropriate, considers the risks to vulnerable populations and minimizes overall business risk. In a nutshell, GMP equals product safety and quality, and defines the responsibilities of the manufacturer to ensure consumers are protected from the distribution of unsafe and ineffective products. Currently, the GMP “landscape” in the cannabis space is complicated. The various “flavors” (food, dietary supplements, cosmetics and drugs/devices) of GMP leave many confused and frustrated when making the decision to implement GMP. Confusion is a result of unclear regulatory requirements as well as operators not fully understanding how to classify or designate the end use of their product(s). Implementing an effective GMP program requires proper planning (both short and long term), financial commitment and qualified resources.

Where Should You Start?

As the regulatory landscape continues to evolve and mature in the cannabis space, your business model must consider GMP implementation if you wish to remain successful and sustainable.

Intended Use

Before you can implement GMP you must first understand what GMP regulations apply to the intended use of your product(s). Are you manufacturing food, beverages or dietary supplements? Get acquainted with the FDA Code of Federal Regulations (CFRs) on GMP. 

Conduct a Gap Assessment

A gap assessment allows you to determine your deficiencies in relation to GMP compliance. The assessment should include, but is not limited to facility design, equipment design, supply chain, risk management and employee training.

Develop an Action Plan

Once the gap assessment is complete a comprehensive action plan will be developed to map out the steps required to achieve GMP compliance. The action plan should follow the SMART Goal principles:

  • Specific (simple, well-defined)
  • Measurable (meaningful)
  • Attainable (achievable, agreed upon)
  • Relevant (resource-based, reasonable and realistic)
  • Timely (time-based, defined due dates)

The plan will include prioritized deliverables, due dates and allocated resources in order to strategically plan and execute and complete the required tasks.

Schedule a Mock GMP Inspection

A mock inspection verifies that the action plan was adequately executed. Hire an experienced resource familiar with related GMPs and QMS to conduct the inspection. A successful mock inspection is a perfect litmus test if the end goal is to achieve GMP certification.

Cannabis manufacturers that ignore the obvious progression toward an FDA-like industry will not survive the long game. Those that embrace the momentum and properly plan to mitigate product and business risk – those who demonstrate integrity and are truly in this space to ensure safe, effective and quality products to consumers will come out on top, gain credibility and secure brand recognition.

Learning from The First Wave Part 3: Seven Basic Questions About Local Cannabis Ordinances & Real Estate

By Todd Feldman
No Comments

Part One of this series took a look at how the regulated cannabis market can only be understood in relation to the previous medical market as well as the ongoing “traditional” market. Part Two of the series describes how regulation defines vertical integration in California cannabis.


If you are considering getting involved in California cannabis, imagine the following sentence in ten-foot-tall letters made out of recently ignited $20 bills:

Before you put any money down on property, carefully examine the local cannabis ordinance and tax rates. 

This article is written in the form of advice to a newbie cannabis entrepreneur in California, but it will discuss issues that are also of significance to investors, as well as (to various degrees) cannabis entrepreneurs in other states.

Here are seven basic questions that you need to ask about local regulations (in order, except for Number 7).

1. What’s Your Jurisdiction?

If you’re in city limits, it’s the city. If you’re outside city limits, it’s the county.

2. Does the Jurisdiction Allow Cannabis Activities?

If the answer is yes, go to the next question. If the answer is no, pick another jurisdiction.

3. Where Does the Jurisdiction Allow Cannabis Activities?

A zoning ordinance will limit where you can set up shop. The limitation will probably vary by license type.

4. How Does the Local Ordinance Affect Facility Costs?

The short answer is: in many ways. Your local ordinance is a Pandora’s box of legal requirements, especially facility-related requirements.1 Read your local cannabis ordinance very carefully.

Generally speaking, the cannabis ordinance will set out two types of requirements – those that are specific to cannabis and those that apply generally to any business.

Looks great but . . . where are the sprinklers? Does it need a seismic upgrade? How about floor drains?

Cannabis-specific requirements:

  • Typically incorporate state cannabis laws by reference.
  • Have significant overlaps with state cannabis laws. For example, the state requires commercial-grade locks and security cameras everywhere cannabis may be found on a given premises. Local ordinances generally include similar requirements – keep in mind that you will need to comply with a combined standard that satisfies both state and local requirements.2
  • Vary greatly according to type of activity. For example, manufacturers will need to comply with Health & Safety Code requirements that can have a major impact on construction costs.
  • Vary greatly by jurisdiction when it comes to equity programs.

General requirements:

  • Include by reference building and fire codes, which can require very expensive improvements. Note that this means your facility will be inspected by the building department and the fire department.
  • Can include anything from Americans with Disabilities Act (ADA) requirements to city-specific requirements, such as Design Guidelines.
  • Will be zealously enforced because you’re a cannabis business.

5. What is the Enforcement Policy?

It may be that your local jurisdiction will give you temporary local authorization after meeting some, but not all, of the requirements. For example, you may be able to begin operations once you’ve provided your city or county with your cannabis permit application, a zoning clearance and a business permit. In this jurisdiction, you would be able to bring your building up to code sometime after you begin operations.

On the other hand, your local jurisdiction may require you to meet every requirement – from cannabis-specific security requirements to general building code and ADA requirements – before you can begin operations. Depending on the type of cannabis business (and facility condition), this might be inconsequential. Or it might mean that you will have to pay more than a year’s worth of rent (or mortgage) before you can start making money.

6. Can You Choose a Facility That Saves You Time and Money?

Of course, you won’t have to spend much time or money bringing your facility up to code if it’s already up to code. How likely it is that you will find such a facility varies wildly according to the type of cannabis activity in question. In general:

  • Service-side activities (delivery retail, storefront retail, distribution) are in many respects similar to their non-cannabis counterparts. From a facilities standpoint, the major differences come from security requirements. So, it may be possible to save time and money by choosing a facility that is already up to code for a similar use.
  • Manufacturing activities are trickier, since you will need food-grade facilities and equipment. You may be able to save money by setting up shop in a commercial kitchen.
  • Extraction with volatile solvents is a special (and particularly expensive) case, since it is inherently dangerous and requires special facilities.
  • Outdoor cultivation may be relatively unproblematic if it has an appropriate water source.
  • Indoor cultivation is expensive because of climate-control and lighting requirements. Buildings potentially suitable for large-scale indoor grows frequently come with significant problems. Former warehouses will typically require major power upgrades, while former factories may have inconvenient architecture and/or hidden toxic waste. In all cases, internal reconstruction is likely to be necessary, and will trigger all sorts of building and fire code requirements.

7. What Are the Local Cannabis Taxes?

Cannabis tax rates may be determinative. For example, Oakland imposes a 6.5% gross receipts tax on manufacturers that have gross receipts of less than $5M, and 9.5% on manufacturers that have gross receipts over $5M. In comparison, Santa Rosa only imposes a 1% gross receipts tax on manufacturers.

Local cannabis ordinances and taxes can make or break your business, so you need to understand them before you commit to a location. The seven basic questions listed above are designed to get you started.

This article is the opinion of the author and is not intended to be legal or other advice.

New Jersey Legalizes Adult Use Cannabis

On February 22, 2021, New Jersey Governor Phil Murphy signed three bills into law, all of which legalize adult use cannabis in the state. A21 is the New Jersey Cannabis Regulatory, Enforcement Assistance, and Marketplace Modernization Act. A1897 is the accompanying decriminalization legislation and A5342 addresses discrepancies between the bills referencing underage possession.

Back in November 2020, voters in New Jersey overwhelmingly approved Question 1 by a 66% to 33% margin. That ballot measure made it to voters by way of the legislature, after New jersey lawmakers failed to pass a legalization bill in 2019. The legislation that Governor Murphy signed yesterday essentially put the will of the voters into law.

The legislation becomes effective immediately upon the Governor signing the bills, but New Jersey residents won’t see legal adult use cannabis until June 2021, the deadline for the five-member Cannabis Regulatory Commission to establish detailed regulations. Possession of cannabis will also not be legal until sales are underway.

The license application window will open 30 days prior to the regulatory deadline. The legislation provides for licenses in cultivation, manufacturing, wholesale, distribution, retail, delivery and testing labs. Until 2023, cultivator licenses will be capped at 37. 25% of all of the licenses are earmarked for microbusinesses that are owned locally and have less than ten employees.

According to New Jersey-based cannabis lawyer Jennifer Cabrera of Vicente Sederberg LLP, the bills include a number of provisions aimed at promoting social equity in the cannabis industry and repairing damage caused by prohibition. The language mandates that 30% of licenses must go to businesses owned by women, minorities or disabled veterans. At least 25% should be allocated to residents of impact zones, which are municipalities that have more than 120,000 residents that: rank in the top 40% of municipalities in the state for cannabis-related arrests; have a crime index of 825 or higher; and have a local average annual unemployment rate that ranks in the top 15% of municipalities.

Advocates across the state are applauding the government’s work to include social equity provisions in the bills. States like Illinois and Massachusetts initially received a lot of praise for including a number of social equity provisions in their legalization plans, but the rollout has left a lot to be desired. Social equity applicants in Illinois are still waiting on licensing as lawsuits play out in court following allegations of corruption and ineffective distribution.

However, it looks like New Jersey is taking a much more thorough approach to social equity issues than other states. “New Jersey has adopted some of the strongest social equity provisions we’ve seen,” says Cabrera. “Contemplating these issues at the outset of the process will likely prove to be a big advantage for the state. It is much easier to build these considerations into the system than it is to go back and incorporate them later.” In other words, there is still a lot of work to be done to ensure an equitable regulatory framework is established.

Amol Sinha, executive director of the American Civil Liberties Union (ACLU) of New Jersey says the state’s laws can set a new standard for what justice can look like. “This is a new beginning – and the culmination of years of advocacy – and we must keep in mind that it is only the start,” says Sinha. “Signing these laws puts in motion the next phase of this effort: to work relentlessly to transform the principles of legalization into greater racial and social justice in New Jersey.”

It is estimated that New Jersey’s adult use cannabis market could be worth more than a billion dollars. As the state begins their rollout and implementation, all eyes are on New York and Pennsylvania, which are both expected to legalize adult use cannabis within the next two years. Both Governor Cuomo of New York and Governor Wolf of Pennsylvania have been clamoring for adult use legalization in recent months.

Flower-Side Chats Part 1: A Q&A with Sam Ghods, CEO of Connected

Flower continues to be the dominant product category in US cannabis sales. In this “Flower-Side Chats” series of articles Green interviews integrated cannabis companies and flower brands that are bringing unique business models to the industry. Particular attention is focused on how these businesses navigate a rapidly changing landscape of regulatory, supply chain and consumer demand.

Connected is a vertically-integrated cannabis company based out of Sacramento, CA and one of the most sought-after brands in California and Arizona. Having formed as a legacy operation in 2009, Connected has created a cult-like following over more than a decade in business. According to BDS Analytics, Connected Cannabis and their acquired brand Alien Labs now boasts the highest wholesale flower price in any major legal market – their average indoor flower wholesale price is 2x the CA average – yet also has the highest flower retail revenue.

We spoke with Sam Ghods, CEO of Connected to learn more about his transition from tech to cannabis, how Connected thinks about product and his vision for future growth. Sam joined Connected in 2018 after getting to know the founders. Prior to Connected, Sam was a co-founder at Box where he stayed on for 3 years after their successful IPO.

Aaron Green: How did you get involved in the cannabis industry?

Sam Ghods: I originally came from the tech industry. I co-founded Box, a cloud sharing and storage company, in the mid 2000s with three other friends. We grew that from the four of us to eventually a multi-billion-dollar public offering in 2015. I stayed on a few more years after that until I took some time off trying to decide what I wanted to do next. I looked at a number of different industries and companies, but personally I always had a real passion for artisan and craft consumer goods. It’s a really big hobby of mine. Whether it’s going to Napa or learning about different kinds of premium consumer goods, I really had a deep love and never knew cannabis could be like that.

When I first met Caleb, the co-founder of Connected, he instantly got my attention by telling me that they had been selling out of their product in the volume of millions of dollars a year at more than two times what everybody else was selling for. That really piqued my interest because creating a product that has that level of consumer passion and demand is maybe the single hardest thing about building a consumer goods business. For them to have been so successful in what was a very difficult and gray market to operate in at the time – this was mid 2018 that I was speaking with him and he had been building this company since 2009 – is a really big challenge, and really impressive.

Sam Ghods, CEO of Connected

So, I started spending time with Caleb and the Connected team and learned a lot about the business. Everything I learned got me more interested and more excited. The way that they thought about the product, the way they treated it was with a reverence and level of sophistication I had no idea was possible.

I was so excited to just learn about the space. I mean, honestly, it feels like the internet in the 90’s- The sheer possibility and excitement. The only difference here is that the market already has existed for 100 years plus: the gray and underground markets for this product are actually phenomenally mature. And now we’re lifting up billions of dollars in commerce that’s already occurring and attempting to legalize all of it in one fell swoop, which creates such an interesting set of challenges.

I first got involved as an advisor on fundraising and strategy. And then a few months later, they were looking for a CEO and I joined full time as CEO in September 2018.

Aaron: What trends in the industry are you focused on?

Sam: It may seem basic, but I think product quality in the broader cannabis markets nationally and internationally is really underrated. Because of the extreme weight of the regulatory frameworks in so many different markets, it’s resulting in a lot of product being grown and sold just because it can be by the operators that are doing it. In many markets, they count the number of producers by the handful, instead of being measured in hundreds or thousands like in California or Oregon. And in that kind of environment, you’re not really having competition, and you’re not really able to see the quality that has existed in this category for years and years and years.

That’s one of the things that really sets us apart – the quality is first above all else, as well as the innovation and time that has gone into it, and not many existing brands in the legal market can say that. With some of the “premium” brands on the market, it would be comparable to just jumping into the wine industry one day and thinking that you can become a premium brand, without having any knowledge of the history of the product or the industry itself. At Connected, we have a team that’s been doing this for over a decade. We did a back of the envelope calculation: there’s over one thousand lifetime harvests between our team. We’ve also brought in specialists from Big Ag and other industries to complement that experience.

Cannabis is a very, very difficult plant to grow at a very high level. It’s much more like high-end wine or spirits than other fruit or produce. I think in the cannabis community, that’s extremely acknowledged, and appreciation for that is the reason we get by with the highest prices in the legal market. I think in the broader investor and financial community, this point hasn’t really hit home, because the limited license markets aren’t mature enough, and there isn’t enough competition in many of them.

Our focus is continuing to make the best product we can, which has fed and developed our brands [Connected and Alien Labs] into what they are today. That is our number one focus, and we think it’s pretty unique to the space of not just cultivating a great quality product, but also as far as breeding, pushing the bar higher and higher on what can be done with the genetics of the plant. 

Aaron: How do you think about choosing testing labs?

Sam: So, the number one criterion is responsibility and compliance. We must be completely confident that they’re testing accurately, safely and exactly to the specifications of the state. Then from there, it is really cultivating about a partnership. There’s a lot of nuance in the relationship with a testing lab. We note things like: Are they responsive? Are they sensitive to our needs in terms of either timelines or requirements we have? It does come down to timelines and costs to a certain extent, like who’s able to deliver the best service for the best cost, but it really is a partnership where you’re working together to deliver a great product. Reliability and consistency are big pieces as well.

Aaron: Industry estimates for illicit market activities are something like 60% of the California market. From your perspective, how do we fix that?

Sam: I think it probably comes down to funding for the efforts to discontinue those activities and opening up the barrier to entry, incentivizing “illegal” operators to make the investment in the cross-over. I think the most successful attempts to tamp it down was when there were initiatives that were well-orchestrated and well-funded, allowing for legacy growers to actually cross over to the “legal” industry. You can’t launch an industry with such an extreme amount of regulation, set a miles-high barrier to entry, and then penalize legacy growers for continuing their business as-is. If the illicit market continues to be fueled by rejection, you’re not going to achieve the tax revenue that you’re expecting to see, that we all want to see. There needs to be an attitude that every dollar put into transitioning illicit markets into regulated markets is returned many times over in tax revenue to the state’s citizens.

Aaron: So, I understand you sell wholesale. Do you sell direct to consumer?“Once they hit the shelves, we blow people away again, beyond their expectations of what they had before.”

Sam: We own and operate three retail stores, so we do sell direct to our consumers, but at this point the majority of our product is sold through third party dispensaries.

Aaron: Do you make fresh frozen?

Sam: We do. On the cultivation side we have indoor, mixed light and outdoor. We fresh freeze a portion of our outdoor harvest every year, and then we use that fresh frozen for our live resin products, for example, our recent live resin cartridge. It creates a vape experience really unlike any other because we are using our regular market-ready flower, but instead we’re taking that flower and actually extracting, not just using the distillate and mixing a batch of terpenes with it. We extract the entire plant’s content across the board, from cannabinoids to terpenoids and everything in between, and then you have our live resin cartridges.

Aaron: How do you think about brand identity and leveraging the brand to command higher prices?

Sam: The cycle we’ve effectively created is that every time we do a release of a new strain or a new batch or harvest, the quality is generally going up. That quality is released under our brands, and then the customer is able to associate that increase in quality and reputation with those brands. Then for our next launch, we have an even bigger platform to talk about the products and to ship and distribute and sell the products. Once they hit the shelves, we blow people away again, beyond their expectations of what they had before. That continuous cycle keeps fortifying the brand and fortifying the product. From our perspective the brand is built 100% on the quality of the product. The product will always be our highest priority and the brand will come downstream from that. 

Aaron: Tell me about Alien Labs.

Sam: Alien Labs was an acquisition. It was a company that had built their brand really successfully in the gray market through 2017 and Prop 215 in California and had an incredible level of quality, a really loyal and dedicated fan base, not to mention a tremendous Instagram presence and following, which is where 98% of cannabis marketing happens today. We really loved the spirit of what the founders were bringing to the table. In 2018, we decided basically to join forces with them and bring them on board, creating a partnership where they leverage our infrastructure and the systems and processes we’ve built, but still keep their way of cultivation and their product vision. To this day, Ted Lidie, one of the founders, continues as the lead brand director for Alien Labs.

Aaron: In what geographies do you currently operate?

Sam: Our primary offices and facilities are based out of Sacramento, California, but we have facilities throughout the state. Last year, for the first time we launched operations in a new state, Arizona. As you may know, you’re not allowed to take cannabis products across state lines at all, so if you want consistent product in multiple markets you really have no choice but to rebuild your entire infrastructure in each state you want to open up.

There are many brands that are expanding and launching in more markets more quickly, but they’re doing so by taking product that’s already existing and putting their brand name on it. That is something we’ve decided strategically that we will not do. We’ve spent years building a high level of trust with our customers, so we’re only going to put our brand name on products that are our genetics, our cultivation, our style, our quality of product. When we launched in Arizona, we did it with a facility that we leased and took over and now operate with our staff. We’re replicating the same exact product that you can get in California in Arizona, which is really exciting.

We launched just this past November, which has been incredibly successful. Our dispensary partner Harvest saw lines of dozens of people out the door.“We consider ourselves a flower company first and foremost, so for us, that was a very calculated strategic move.”

Aaron: Any new geographies on the horizon that you can talk about?

Sam: We’re constantly evaluating new opportunities. I don’t have anything particularly specific to announce right now, but I will say we look for states where we believe there’s a competitive environment where the product quality is going to really stand out and be appreciated.

Aaron: Do you notice any differences in consumer trends between California and Arizona that stand out?

Sam: Not too many yet. We don’t have a retail location in Arizona, so we don’t have as much direct contact. However, we have heard consistently that the Connected customer demographics – as you would imagine most interested in our product – are those looking for something special, unique, different and have a really superior quality to everything else out there. We ended up launching in Arizona with the highest price point for flower in the state, and we say that’s just the beginning. The market is still so young and immature, both nationally and internationally, that this category is going to develop into one that’s really taste-driven.

Aaron: What’s next in California?

Sam: Continued growth and product development. We want to keep blowing away our customers with more and more incredible products, different product types and categories. For example, the cartridges were a really big launch for us because we don’t really consider ourselves a vape company. We consider ourselves a flower company first and foremost, so for us, that was a very calculated strategic move. We were only going to launch the product if we could fully replicate what the consumer gets from the flower experience. We are very unlikely to ever release a distillate pen, for example.

Aaron: What are you personally interested in learning more about?

Sam: We, as a society, really don’t know very much about the cannabis plant. Pretty much all meaningful research around cannabis stopped in the early 1900’s with prohibition. In the meantime, we’ve performed millions of dollars of studies and research on almost every other plant that we grow commercially. We understand these plants extraordinarily well. Cannabis science is stuck back in agriculture of early 1900s. The most interesting conversations I have are around how the plant works, how it doesn’t work and the ways in which it is so different from all other plants with which we are familiar. Our head of cultivation comes from Driscolls, the largest berry company in the world, and even he is frequently surprised by the way the cannabis plant reacts to things that are commonly understood in other plants. So, the way the actual plant responds to different environments is truly fascinating and something I think we’ll be learning about for decades and decades to come.

Aaron: Okay, great. That concludes the interview. Thank you, Sam!

How Rare Cannabinoids Will Impact Investing

By Maxim Mikheev, Dennis O’Neill
No Comments

There is a significant increase in demand for all cannabinoid products across the board—including CBD, THC, CBG and THCV—from recreational users, consumer packaged goods and pharmaceutical companies. And the next great race is on for the hottest arrival to scientific cannabis therapeutics: rare cannabinoids.

Research shows rare cannabinoids are poised to be the future of cannabis investing, providing better health benefits in addition to impacting the pharmaceutical, CPG, nutraceuticals, cosmetics and pet care markets significantly. According to recent reports, the biosynthesis of rare cannabinoids will be a $25 billion market by 2025 and $40 billion by 2040.

The companies that will revolutionize this market are ones with the highest quality and lowest prices, which means that biosynthetic cannabinoid companies will be the leaders in investment and capturing market share. We will also see a major consolidation in this market amongst the grow, harvest and extraction companies, increasing efficiencies and driving down costs.

What are rare cannabinoids and why should we care?

Tetrahydrocannabivarin (THCV)

Rare cannabinoids such as CBG, CBN, THCV, THCA and others have significantly better and more specific health benefits than just CBD on its own. Biotech companies like ours, Biomedican, which has a patent-pending biosynthesis platform, can produce pharmaceutical grade, non-GMO, bioidentical, synthetic cannabinoids with 0.0% THC at 70-90% less cost. Producing 0.0% THC means that rare cannabinoids can be added into nutraceuticals, CPG and cosmetics/lotions with zero changes in current cannabis regulations. Also, we produce the same exact product every time (not possible through plants), which is extremely important for pharmaceutical companies conducting clinical trials.

Why are rare cannabinoids important?    

The human body contains different cannabinoid receptors that help regulate critical processes, including learning, memory, neuronal development, appetite, digestion, inflammation, overall mood, sleep, metabolism and pain perception. This considerable involvement of cannabinoid receptors, critical to many physiological systems, underscores their potential as pharmaceutical targets.

Tetrahydrocannabinol (THC), just one of hundreds of cannabinoids found in cannabis.

Pharmacological research has uncovered several medical uses for cannabinoids, which bind to cannabinoid receptors. They’ve been shown to help with pathological conditions such as pediatric epilepsies, glaucoma, neuropathic pain, schizophrenia and have anti-tumor effects as well as promote the suppression of chemotherapy-induced nausea. This ongoing research is becoming more prevalent and has the potential to uncover therapeutic uses for an array of cannabinoids.

In addition to the medical field, other prominent sectors have adopted the use of cannabinoids. There is an increasing demand for cannabinoids in inhalables, the food industry and in hygienic and cosmetic products. Veterinary uses for cannabinoids are also coming to light. The use of naturally occurring cannabinoids reduces the need for synthetic alternatives that may produce harmful off-target effects. 

So how does this affect the investing market?

Where there is demand, significant and growth investments follow. All the major players from nutraceuticals, CPG, cosmetics and pet care companies are driving the demand for rare cannabinoids. We are seeing a major investment shift from commodity-based prices for cannabis and CBD to the new biosynthesis technology which offers significantly better health benefits and higher profit margins. Those unique qualities of rare cannabinoids open an enormous opportunity to create new drugs and food supplements for treating various medical conditions and improving the quality of life. This creates a massive global opportunity for all companies in these categories differentiating their products from competitors.

The structure of cannabidiol (CBD)

There will be big winners and losers in these markets, but at the end of the day, the highest quality and lowest cost producers will capture most of these markets. Biomedican has the highest quality, highest yields and lowest cost of production in the industry. Which we believe will make us the clear leader in the biosynthesis rare cannabinoid markets.

Which rare cannabinoid to invest in first?

Early reports indicate THCV (not to be confused with THC) could contain a variety of health benefits: it may help with appetite suppression/weight loss, possibly treat diabetes as well the potential to reduce tremors and seizures caused by conditions like multiple sclerosis, Parkinson’s disease and ALS.

There has been an explosion of interest in THCV due to its potential health benefits. We are seeing major players in the nutraceutical, health food and pharmaceutical industries clamoring to add THCV to their product lines. Companies can now produce THCV through biosynthesis, creating a pharmaceutical-grade, organic, bioidentical compound at 70-90% less than wholesale prices. This is exactly what the largest players in the market want: a pharmaceutical-grade, consistent product at significantly less cost. The current prices and quality have limited THCV production, but new breakthroughs in biosynthesis have solved those issues, so we expect a tsunami of orders for THCV in 2021.

THC Remediation of Hemp Extracts

By Darwin Millard
1 Comment
extraction equipment

Remediation of delta-9 tetrahydrocannabinol (d9-THC) has become a hot button issue in the United States ever since the Drug Enforcement Agency (DEA) released their changes to the definitions of marijuana, marijuana extract, and tetrahydrocannabinols exempting extracts and tetrahydrocannabinols of a cannabis plant containing 0.3% or less d9-THC on a dry weight basis from the Controlled Substances Act. That is because, as a direct consequence, all extracts and tetrahydrocannabinols of a cannabis plant containing more than 0.3% d9-THC became explicitly under the purview of the DEA, including work-in-progress “hemp extracts” that because of the extraction process are above the 0.3% d9-THC limit immediately upon creation.

The legal ramifications of these changes to the definitions on the “hemp extracts” marketplace will not be addressed. Instead, this article focuses on the amount of d9-THC that is available in the plant material prior to extraction and tracks a “hemp extract” from the point it falls out of compliance to the point it becomes compliant again and stresses the importance of accurate track-n-trace protocols at the processing facility. The model developed to support this article was intended to be academic and was designed to follow the d9-THC portion of a “hemp extract” through the lifecycle of a typical CO2-based extract from initial extraction to THC remediation. A loss to the equipment of 2% was used for each step.

Initial Extraction

For this exercise, a common processing scenario of 1000 kg of plant material at 10% cannabidiol (CBD) and 0.3% d9-THC by weight was modeled. This amount, depending on scale of operations, can be a facility’s total capacity for the day or the capacity for a single run. 1000 kg of plant material at 0.3% d9-THC has 3 kg of d9-THC that could be extracted, purified, and diverted into the marketplace. CO2 has a nominal extraction efficiency of 95%, meaning some cannabinoids are left behind in the plant material. The same can be said about the recovery of the extract from the equipment. Traces of extract will remain in the equipment and this little bit of material, if unaccounted for, can potentially open an operator up to legal consequences. Data for the initial extraction is shown in Image 1.

Image 1: Summary Data Table for Typical CO2-based Extraction of Phytocannabinoids

As soon as the initial extract is produced it is out of compliance with the 0.3% d9-THC limit to be classified as a “hemp extract”, and of the 3 kg of d9-THC available, the extract contains approx. 2.8 kg, because some of the d9-THC remains in the plant material and some is lost to the equipment.

Dewaxing via Winterization and Solvent Removal

Dewaxing a typical CO2 extract via winterization is a common process step. For this exercise, a wax content of 30% by weight was used. A process efficiency of 98% was attributed to the wax removal process and it was assumed that 100% of the loss can be accounted for in the residue recovered from the equipment rather than in the removed waxes. Data for the winterization and solvent recovery are shown in Image 2 and 3.

Image 2: Summary Data Table for Typical Winterization of a CO2 Extract
Image 3: Summary Data Table for Solvent Removal from a CO2 Extract

Two things occur during winterization and solvent removal, non-target constituents are removed from the extract and there is compounded loss from multiple pieces of process equipment. These steps increase the concentration of the d9-THC portion of the extract and produce two streams of noncompliant waste.

Decarboxylation & Devolatilization

Most cannabinoids in the plant material are in their acid form. For this exercise, 90% of the cannabinoids were considered to be acid forms. Decarboxylation is known to produce a mass difference of 87.7%, i.e. the neutral forms are 12.3% lighter than the acid forms. Heat was modeled as the primary driver and a process efficiency of 95% was used for the conversion rate during decarboxylation. To simplify the model, the remaining 5% acidic cannabinoids are presumed destroyed rather than degraded into other compounds because the portion of the cannabinoids which get destroyed versus degrade into other compounds varies from process to process.

Devolatilization is the process of removing low-molecular weight constituents from an extract to stabilize it prior to distillation. Since the molecular constituents of cannabis resin extracts vary from variety to variety and process to process, the extracts were assumed to consist of 10% volatile compounds. The model combines the decarboxylation and devolatilization steps to account for complete decarboxylation of the available acidic cannabinoids and ignores their weight contribution to the volatiles collected during devolatilization. Destroyed cannabinoids result in an amount of loss that can only be accounted for through a complete mass balance analysis. Data for decarboxylation and devolatilization are shown in Image 4.

Image 4: Summary Data Table for Decarboxylation and Devolatilization of a CO2 Extract

As the extract moves along the process train, the d9-THC concentration continues to increase. Decarboxylation further complicates traceability because there is both a known mass difference associated with the process and an unknown mass difference that must be calculated and justified.

Distillation

A two-pass distillation was modeled. On each pass a portion of the extract was removed to increase the cannabinoid concentration in the recovered material. Average data for distilled “hemp extracts” was used to ensure the model did not over- or underestimate the concentration of the cannabinoids in the distillate. The variables used to meet these data constraints were derived experimentally to match the model to the scenario described and are not indicative of an actual distillation. Data for distillation is shown in Image 5.

Image 5: Summary Data Table for Distillation of a Decarboxylated and Devolatilized Extract

After distillation, the d9-THC concentration is shown to have increased by 874% from the original concentration in the plant material. Roughly 2.2 kg of the available 3 kg of d9-THC remains in the extract, but 0.8 kg of d9-THC has either ended up in a waste stream or walking out the door.

Chromatography – THC Remediation Step 1

Chromatography was modeled to remove the d9-THC from the extract. Because there are several systems with variable efficiency rates at being able to selectively isolate the d9-THC peak from the eluent stream, the model used a 5% cut-off on the front-end and tail-end of the peak, i.e. 5% of the material before the d9-THC peak and 5% of the material after the d9-THC peak is assumed to be collected along with the d9-THC. Data for chromatography is shown in Image 6.

Image 6: Summary Data Table for d9-THC Removal using Chromatography

After chromatography, a minimum of three products are produced, compliant “hemp extract”, d9-THC extract, and noncompliant residue remaining in the equipment. The d9-THC extract modeled contains 2.1 kg of the available 3 kg in the plant material, and is 35% d9-THC by weight, an increase of 1335% from the distillation step and 11664% from the plant material.

CBN Creation – THC Remediation Step 2

For this exercise, the d9-THC extract was converted into cannabinol (CBN) using heat rather than cyclized into d8-THC, but a similar model could be used to account for this scenario. The conversion rate of the cannabinoids into CBN through heat degradation alone is low. Therefore, the model assumes half of the available cannabinoids in the d9-THC extract are converted to CBN. The entirety of the remaining portion of the cannabinoids are assumed to convert to some form of degradant rather than a portion getting destroyed. Data for THC destruction is shown in Image 7.

Image 7: Summary Data Table for THC Destruction through Degradation into CBN

Only after the CBN cyclization step has completed does the product that was the d9-THC extract become compliant and classifiable as a “hemp extract.”

Image 8: Summary Data Table for Reconciliation of the d9-THC Portion of the Hemp Extract

Throughout the process, from initial extraction to the final d9-THC remediation step, loss occurs. Of the 3 kg of d9-THC available in the plant material only 2.1 kg was recovered and converted to CBN. 0.9 kg was either lost to the equipment, destroyed in the process, attributable to the mass difference associated with decarboxylation, or was never extracted from the plant material in the first place. All of these potential areas of product loss should be identified, and their diversion risk fully assessed. Not every waste stream poses a risk of diversion, but some do; having a plan in place to handle waste the DEA considers a controlled substance is essential. Without a track-n-trace program following the d9-THC and identifying the potential risk of diversion would be impossible. The point of this is not to instill fear, instead the intention is to shed light on a very real issue “hemp extract” producers and state regulators need to understand to protect themselves and their marketplace from the DEA.
