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 integrate innovative practices in order to navigate a rapidly changing landscape of regulatory, supply chain and consumer demand.

Large-scale agricultural practices can take a toll on soil health leading to inefficiencies over the long term. Harvey’s All Naturals is a Colorado-based company specializing in premium farm-to-table full spectrum CBD products. Harvey’s gets all of its hemp from Boot Ranch Farms, an off-grid sustainable hemp farm in Southern Colorado supplied by an artesian well.

We spoke with Harvey Craig, CEO Harvey’s All Naturals and co-founder of Boot Ranch Farms, to learn more about the benefits of regenerative agriculture, how he thinks about soil health, and how they produce their CBD products. Harvey started Boot Ranch Farms in 2014 after the passing of the Farm Bill and Harvey’s All Naturals followed shortly thereafter.

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

Harvey Craig: I got involved at a very young age, as the youngest of eight kids, seven of which are boys, I was introduced to cannabis on the marijuana side first. As an engineer through the years, I’ve always been involved in creating very efficient growing systems for cannabis.

Harvey Craig, CEO Harvey’s All Naturals and co-founder of Boot Ranch Farms

In the early 2000s, I learned about CBD a little bit through experimenting with marijuana strains to help a friend who had Parkinson’s and also through the research performed by Raphael Mechoulem, an organic chemist and professor at the Hebrew University of Jerusalem in Israel. In 2014, when the Farm Bill made hemp legal, I dropped everything and went into it because I felt “this is what I need to be doing.”

Green: What is sustainable farming mean to you?

Craig: Sustainable farming to me means putting soil health and responsible natural growing practices at the forefront of all agriculture – regenerative processes for soil, in a nutshell. To me, soil health is one of the biggest problems in the United States right now. By regenerating and making our soils living, healthy and with a rich nutrient base we create an ecosystem that is good for human health and health all around.

Green: What do you mean specifically when you say, “soil health?”

Craig: Soil is living. A good natural soil has a living microbiotic structure inside it. There’s a living habitat that forms inside our soil over the years. Large scale agriculture in many cases has depleted or killed this living structure through readily accessible fertilizers and tilling practices.

Farmers understand the soil. There are practices we can undertake that are helping our living soils and helping the microbiotic habitat to thrive. Practices such as no-till technologies, rotating crops, using cover crops, not being a monocrop, responsible water use, healthy fertilizer and pesticide technologies, minimal processing, the list goes on and on…

When we talk about this thing called sustainability, I think it’s very important that we understand there are two sides of cannabis. There’s the marijuana and then there’s the hemp. We can’t put those two together – they’re governed very differently. Hemp became legal through the Farm Bill and is governed by the Department of Agriculture. Hemp is just like any other crop out there really. That means we can mix hemp in with other crops. It’s very much like corn and other crops in how it’s grown on a large scale, industrial basis.

Marijuana on the other hand is governed by each state’s regulatory commission. Those regulations make it very hard to mix in with general agriculture. So, when it comes to the marijuana side, unfortunately, it must be a monocrop. Most marijuana is grown in pots and pots are fine. However, if you are just growing in a pot and then throwing your soil away, that is not very sustainable. As it sits right now, in the marijuana industry there is really no sustainability, unfortunately. The energy use for the lights in indoor grows, for example, creates a huge carbon footprint and load on the electrical grid. I’m not trying to put indoor growing down, but that’s the way it is. The only way I foresee sustainability in the marijuana side of cannabis is to let loose a little bit on regulation and allow it to become a part of normal agricultural processes.

Green: What is it about tilling that degrades the soil quality?

Craig: When we till our soil, we’re turning the organisms in the soil up and we’re allowing the sun to dry them out. If it’s not done properly, you kill that soil structure.

Now, these little microorganisms in our soil create a healthy soil, but it doesn’t happen instantly, this takes years to create. Nobody has the time anymore, everybody’s “go go go” and “make it happen instantly”. So that gets destroyed. Now we have all these dead soils that everybody’s growing in and growers turn to factory-produced fertilizers with readily available nutrients.

When we are talking about cannabis, we can’t just look at monocropping. If you grow one crop in the same soil over and over, the soil is going to get depleted. One of the main things that we deplete is nitrogen and growing other crops, such as clover, can replenish that nitrogen. Growing cover crops protects the soil from the sun, creates nitrogen for the soil, and holds the water within the soil.

Instead of tilling, you can rotate with crops like root vegetables, radishes and other things that have deep root structures. Instead of tearing them up, just let them degrade organically and go back into the soil. Those deep root structures will also help aerate the soil.

Green: What is a farmer’s first approach?

Craig: Farmers want their land to be healthy. True farmers have a oneness with the earth and understand the earth. The farmer’s first approach keeps the farmer involved in creating new technologies for agriculture.

Green: Let’s say you’re a farmer that has land or recently acquired land that’s been industrially grown upon. How would you take that land and start fresh with a regenerative process?

Craig: The first thing you have to do is take soil samples and send them to a lab. That’ll tell you what you’re working with. Also, knowing a little history about the land helps as well. Was it used for grazing? Was it used for growing corn? What was it used for? Were organic practices used?

Then, there are many things you can do to start to regenerate your soil, but it takes time. In many situations, people don’t want to take that time. But what we’re learning is, the people and the farmers that do take that time often take a hit monetarily for the first two or three years. After that, once that structure is maintained, the natural health of the soil can be replenished. Crops will grow better, and they won’t spend as much money on fertilizers and pesticides in the long run because the microbiotic structure in the soil is creating a healthy ecosystem. When we destroy that ecosystem, it doesn’t come back easily or quickly. If there’s a little bit there, it can be regenerated with the right practices.

Green: I understand that the Boot Ranch is an off-the-grid farm. What was your motivation for either going off-grid or remaining off-grid?

Craig: I have a background in alternative energies and engineering, and when creating Boot Ranch Farms there was a lot that went into the sustainability side of it. The farm is extremely far away from the power grid for starters. So, an investment in solar for electricity was money well spent. My thought process was, why would I invest in bringing the wires in when I could actually save money and resources by creating a very efficient solar system and not be tied to the grid? Our farm is self-sustaining without being connected to any grid, which is one of the main reasons for remaining off-grid.

Green: I understand the farm is supplied by an artesian well. How do you monitor your water quality?

Craig: Well, we’re very fortunate. Existing natural water quality is one of the main reasons we decided to grow in the San Luis Valley. When you’re starting something new, you have to look at your financial side of things. Investing in a hemp farm is very different than the marijuana side because you won’t make as much money per pound of product sold. So, you have to watch your budget and not spend too much, or you’re never going to make a profit.

The self-sustaining artisanal well and water rights were existing on the property. There’s no pumping required for it and the water goes into a 10,000-gallon holding tank, where we can monitor and test for water quality. In order to water our plants, we use a pump/drip water system that supplies water to each individual plant. It’s very efficient compared to most watering systems out there, such as flood irrigation or pivots, and really doesn’t use a heck of a lot of water.

Green: Are you growing in open air or greenhouses?

Craig: We grow in two 3,000 square feet industrial-grade greenhouses at Boot Ranch Farms. Greenhouse One has all the bells and whistles including heating, cooling, light deprivation, supplemental lighting, automated controls and more. That greenhouse allows us to mimic Mother Nature a little bit. We can get up to six harvests throughout the course of the year in that greenhouse. However, in reality, we get about four.

In addition, we have a second greenhouse that is set about 100 feet away and set up to keep plants growing on mother nature’s cycle. We can move groups of mature plants to Greenhouse One after each harvest for multiple flowering cycles. Lastly, between greenhouses, we have a 10,000 square foot courtyard that’s protected with shade cloth and other things to help protect those plants from the elements. In late October, all remaining plants in both greenhouses and the courtyard become mature and ready to harvest due to shorter days created by mother nature.

Green: Do you insure your crops?

Craig: We have not. Hemp is a new industry and we have not found good crop insurance.

Green: Do you cultivate your own genetics?

Craig: We work with some other companies here in Colorado to provide genetics. Consistent genetics are extremely important on the hemp side because we need to trust that they are going to keep the THC levels down. On the marijuana side, that part doesn’t matter so much

There are different strains that have been created that I absolutely love, and I’ve tried to stick with them and stay with that seed stock. One of them is called The Wife and the other Cherry Wine. Most of the best hemp I have found is based upon the Cherry strain. People are always looking for high CBD. I’d rather have a lower CBD level in the 8% to 12% range. Something higher in the 14% to 20% range has a higher chance of producing a product with more than the legal amount of THC.

Green: Is Harvey’s All Naturals fully supplied by Boot Ranch Farms?

Craig: Yes, it is. There are a lot of things that go into a quality product and we focus on that at Boot Ranch. We’re small, not trying to compete with the large-scale market. Unfortunately, a high percentage of the products out on the market come from large-scale industrial hemp grows. We focus on long-term medicinal value and grow very high-quality hemp and we try not to degrade it in any way, shape or form throughout processing.

Green: How many square feet or acres is the Boot Ranch Farm?

Craig: Boot Ranch farm is about 260 acres. We only grow on less than three of it.

Green: What’s your extraction process?

Craig: We use cold alcohol extraction. We do not distill to separate our alcohol from the hemp oil. We use what’s called a roto vape. That cold processing preserves our terpenes, it preserves our full-spectrum cannabis oil profile and doesn’t fully decarboxylate our CBDa. We want a large CBDa percentage because there are many things that CBDa is good for when it comes to long term medicinal reasons.

Green: Are you processing your own hemp?

Craig: No, we sub that part of it out. What I’ve learned in this industry is three main parts: 1- the farming; 2- the extraction, and; 3- the product line. Those are three very separate processes and require specialized expertise within themselves. Each is a large investment and it’s very hard to do it all. I decided to work with other people on the extraction part of it. They have the expertise, and we pay them well to do what they do.

Green: Okay, great. And then any final words for Ag Day?

Craig: Support your small farmer in nutrient-rich agricultural products.

Green: Great. That concludes the interview, Harvey!

Craig: Thank you very much!

How to Develop Quality Cannabis Products with Advanced Analytical Testing

By Vanessa Clarke, Melody Lin
No Comments

A thorough cannabis product development process goes far beyond extracting and packaging. Performing advanced analytical testing at each and every stage allows producers to know the quantity, quality and behaviour of compounds in samples. Here are the four key stages from flower to consumption.

Stage 1: Flower

Developing a quality cannabis product begins with knowing the composition of compounds in your starting material. The best analytical tests utilize a metabolomics approach. Metabolomics is a suite of techniques that include a variety of instruments to run samples through in order to receive compositional data. In this stage, LC-qTOF and GC-MS are the best instruments to track all the compounds in the starting plant material. Essentially, metabolomics establishes a fingerprint of the compounds in a plant sample. This is beneficial because producers have to understand how their chosen cannabis plant differs from other cultivars and how it would potentially behave in their desired end product formulations.

Stage 2: Concentrate

After the plant material has gone through an extraction process, producers want to know precisely what is in the extract. Are there compounds that should not be there and are all the desired compounds present? The best way to test the quality of cannabis oils is again to use metabolomics (e.g. via LC-qTOF). This test reveals all the compounds in the sample in order to help the producer determine the purity and consistency of molecules beyond just THC and CBD.

When testing cannabis isolates, it is best to use NMR spectroscopy and X-ray diffraction. NMR characterizes and assesses the purity of single compounds or mixtures in solution or solid state. X-ray diffraction provides information about the crystal structure, chemical composition and the physical properties of the cannabis sample to help the producer prove the identification of desired compounds. Establishing that the concentrates are pure and aligned with what the producer intended to extract is key in this stage of product development.

Stage 3: Formulation

Designing an appropriate drug delivery formula is a universal challenge producers face at this stage of product development. Where nanoemulsion or other carrier approaches are being used, formulation characterization allows producers to understand how their active compounds behave in simulated physiological environments as well as how stable their products are over time. Specifically, nanoparticle sizing and assessing size changes over time can help a formulation scientist ensure the highest quality product is being mixed, and that the desired effect will be imparted on the consumer/patient.

Stage 4: Smoke/Vapor

Many producers might not consider this final stage, but it is critical for all inhalable cannabis products and devices. Using a smoke analyzer and metabolomics testing can identify and quantify compounds present within the formed smoke or vapor from pre-roll joints to vape devices. This is not only important for preventing the production of toxic by-products, but it can help producers create an optimal smoking experience for consumers.

One area that is often an afterthought is quality compliance testing. Despite a number of groups using the required tests well during development, many forget to continue the same robust testing on end products. In the current cannabis product development landscape, there is little guidance on how compliance testing should be conducted on every product “batch.” With these advanced analytical tests, producers can confidently develop compliant, stable and quality cannabis products.

 

The Ten Biggest Mistakes When Building a Cultivation Facility

By Michael Burnstein
3 Comments

As cannabis legalization becomes more prolific across the United States, entrepreneurs are entering the cultivation business in droves. With so many new companies entering the market and growing cannabis, there are a lot of common errors made when getting started. Here are ten of the biggest mistakes you can make when building a cannabis grow facility:

  • Failure to consult with experts in the cannabis business – poor planning in floorplan and layout could create deficient workflow causing extra time and costing profits. Bad gardening procedures may result in crop failure and noncompliance could mean a loss of license. Way too often, people will draft a design and begin construction without taking the time to talk to an expert first. Some important questions to ask yourself and your consultant are: What materials should be used in the building of the grow? Is my bed-to-flower ratio correct? How long will it take before I can see my first harvest? 
  • Contractor selection – DO NOT build your own facility; leave it to the experts. Sure, you have experience building things and you have a friend who has worked in construction. Do not make this mistake – Our experience can save you from the mistake’s others have made. To stay lucrative in this competitive industry and to maximize your products’ quality and yields, have the facility built right the first time. Paying an experienced, qualified cannabis professional to build you a facility will produce better yields and will save you time, stress and money in getting you from start of construction to your first crop.
  • Not maximizing your square footage potential – With today’s fast changing environment, multi-tiered stationary racks, rolling benches and archive style rolling racks help maximize square footage. Without the proper garden layout, you will find yourself pounds short of your potential each harvest.
  • Inadequate power – Not planning or finding out if there is sufficient power available at the site for your current and future needs. This will stop you from building the overall square footage you want. When finding a building make sure you first know how much power you will need for the size grow you want. With proper engineering you will find out what load requirements will be so you can plan accordingly.
  • Material selection – The construction material that goes into a cultivation and extraction facility should consist of nonabsorbent anti-microbial finishes. The days of wood grow benches are long gone. Epoxy flooring, metal studs and other materials are mandatory for a quality-built, long-lasting facility.
  • Hand watering – Once your facility is up and running, many people feel they have spent enough money and they can save by hiring people to water by hand, rather than going with an automated system to handle the watering and nutrients. The problem with this is your employees are not on your plants timetable. What if an employee calls off and can’t come into water at the right time or they mix the wrong amount of nutrients from the formula you have selected? These are issues we see a lot. It is critical to perform precise, scheduled watering and nutrient delivery to increase your yields.
  • Failure to monitor and automate – Automating your grow is important for controlling the light and fertigation schedules as well as data collection and is crucial to maximizing yields. Being able to do this remotely gives you peace of mind in that you can monitor your grow room temperature and humidity at all times and be notified when something is not right.
  • MedicineManTechGrowPoor climate – This can cause stunted growth, smaller harvests and test failures. Our experience has taken us to facilities that have had mold and mildew issue due to poor climate. Proper air balancing, additional dehumidification along with a proper cleaning procedure can get a facility back in working order. Installing proper climate control systems could save millions of dollars.
  • Choosing the wrong site or building – Not knowing the history of the building you are choosing to rent or buy can create logistical and monetary nightmares. The wrong site can be a distribution and marketing disaster. In the wrong building, exponentially more money is spent to bring that building up to the standards needed for successful production and yields. For example, bringing in the ceiling and the cleaning of an existing facility can be a great expense. If you do not know what you are looking at when you purchase, you may be in for months of unaccounted expenses and inaccurate timelines. This can be detrimental for companies and individuals that are on restricted timelines and have to start producing successful and continuous yields from a space that has to be converted into a prime grow facility.
  • Failure to maintain your facility – A dirty site creates an invitation for pests, workplace injuries, unhealthy working environment and equipment failure. Keeping the facility and equipment properly maintained with routine service will ensure efficiency, longevity of equipment life span and reduce mold and bacteria risk. Clean facilities = clean plants and better flower.

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.

Cannabis Registry Reality Check: Privacy Must be Paramount

By Shadrach White
No Comments

The task of preserving privacy for any records platform, especially a cannabis registry, cannot simply be relegated to ones and zeros lurking in some forgotten codebase. This past year taught us many lessons, especially related to the trauma unleashed by vulnerabilities in government domains. We learned time and again that a registrant’s privacy must be the first order of business for the architects of registries.

But the first order of business isn’t the last order of business. That intention and effort to secure privacy must then be communicated and reinforced through real-world reality checks.

Lapses in data security and rising distrust for government institutions block the efficacy of well-intentioned and vital registries. Those states launching new registries in 2021 are at a precarious crossroads as public trust erodes.

As I write this, we’ve just learned illicit operators hacked a third-party service provider for the Washington State Auditor’s office. The attack compromised the personal data of 1.4 million users seeking unemployment benefits. Security hacks are a cautionary tale, whose impact is felt too often.

But many in the government sector are staring at a once-in-a-generation challenge to launch new registries – those related to cannabis – with privacy top-of-mind from the initial Request For Bid.“The question isn’t when these privacy-first registries will be implemented, it’s a question of whether they’ll be implemented proactively ahead of hacks or after the damage is done.”

Here’s how:

Table Stakes for New Cannabis Registries

These suggestions are just the beginning, and I see them as the minimum buy-in to begin the architecture of a new cannabis registry. They include:

  • End-to-end data encryption while in transit and within the system while the data is at rest.
  • A solution that is a cloud-native web application which is managed as a service for maximum uptime and strong security posture.
  • Registries should also leverage algorithms and machine learning to ensure accurate data entry by analyzing incorrect or duplicate data before it is saved within the system.

Beyond HIPAA

The Health Insurance Portability and Accountability Act (HIPAA) requires privacy and security measures to protect Personal Health Information (PHI). Debate exists on whether compliance is a requirement for all entities transacting in the medicinal cannabis space. While some state registries are exempt from HIPAA, others choose to provide HIPAA compliance not just for the optics, but the known benefit to users’ privacy and confidence. New cannabis registries should commit to HIPAA-compliance to set a trusted new privacy standard for medical patient credentials and legal authorization for the use of cannabis for medical purposes.

That’s just the start. Registries should also ensure SOC2 Type II certification, which safeguards security, site availability, confidentiality and privacy through independent third-party auditors.

Connect with Confidence

Registries function as a hub of information in an often-confusing cannabis space. The California Bureau of Cannabis Control displays more than 25 links wired into its top navigation bar alone. Each link sends the curious to new resources. Registries must establish themselves as credible resources, especially when directing users to third-party sites.

One example is for cannabis registries to provide secure access to healthcare professionals who are verified by the Drug Enforcement Agency (DEA). These healthcare professionals are licensed to distribute controlled substances including cannabis. Each third-party link should offer the same high-level of scrutiny to enshrine confidence and credibility in the registry.

Next-Generation ID Cards

A cannabis registry card should not just be a document, but a toolset that attests to the identity and the authority of the carrier represented. An illicit counterfeiting market seeks to exploit registry card vulnerabilities. Next generation ID cards present the best defense against counterfeiting and illegal use with robust security measures. That starts with assuring that any credential is mobile ID compatible with iOS Wallet and GooglePay for mobile identification.

ID cards should also include:

The automated modification of the document bearer’s photograph to ICAO (International Civil Aviation Organization) standards. This critical modification makes the photograph easier to use for ID verification; it also facilitates the detection of photograph substitution.

A two-dimensional barcode compiles information contained in a one-dimensional barcode. It also delivers confirmation of other data shown on the card or in the system such as license authorization and limitations. Adding additional material to the physical document such as holograms, UV image, micro-printing or laser perforations offers another level of protection against illicit use or counterfeiting.

While cannabis registries are the beginning, they’re not the end. Driving efficacy for government registries needed for COVID19 track-and-tracing, cannabis plant track-and-tracing and vaccine distribution require the same attention to privacy, security and ultimate useability. A sea change is required – not just for the sake of those who use the registries but also for those who must implement, deploy and maintain those registries. The question isn’t when these privacy-first registries will be implemented, it’s a question of whether they’ll be implemented proactively ahead of hacks or after the damage is done. I believe the government sector leaders exploring new cannabis registries offer the wisdom and foresight to choose the proactive approach.

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

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.

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

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

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.
