New Guidance on Waste Disposal for Hemp Producers

By Stephanie McGraw, Emily Sellers

On January 15, 2021, the USDA published its final rule on US hemp production. The rule, which becomes effective on March 22, 2021, expands and formalizes previous guidance related to waste disposal of noncompliant or “hot” crops (crops with a THC concentration above .3 percent). Importantly for the industry, the new disposal rules remove unduly burdensome DEA oversight and provides for remediation options.

Producers will not be required to use a DEA reverse distributor or law enforcement to dispose of noncompliant plants. Instead, producers will be able to use common on-farm practices for disposal. Some of these disposal options include, but are not limited to, plowing under non-compliant plants, composting into “green manure” for use on the same land, tilling, disking, burial or burning. By eliminating DEA involvement from this process, the USDA rules serve to streamline disposal options for producers of this agricultural commodity.

Alternatively, the final rule permits “remediation” of noncompliant plants. Allowing producers to remove and destroy noncompliant flower material – while retaining stalk, stems, leaf material and seeds – is an important crop and cost-saving measure for producers, especially smaller producers. Remediation can also occur by shredding the entire plant to create “biomass” and then re-testing the biomass for compliance. Biomass that fails the retesting is noncompliant hemp and must be destroyed. The USDA has issued an additional guidance document on remediation. Importantly, this guidance advises that lots should be kept separate during the biomass creation process, remediated biomass must be stored and labeled apart from each other and from other compliant hemp lots and seeds removed from non-compliant hemp should not be used for propagative purposes.

The final rules have strict record keeping requirements, such rules ultimately protect producers and should be embraced. For example, producers must document the disposal of all noncompliant plants by completing the “USDA Hemp Plan Producer Disposal Form.” Producers must also maintain records on all remediated plants, including an original copy of the resample test results. Records must be kept for a minimum of three years. While USDA has not yet conducted any random audits, the department may conduct random audits of licensees.

Although this federal guidance brings some clarity to hemp producers, there still remains litigation risks associated with waste disposal. There are unknown environmental impacts from the industry and there is potential tort liability or compliance issues with federal and state regulations. For example, as mentioned above, although burning and composting disposal options for noncompliant plants, the final rule does not address the potential risk for nuisance complaints from smoke or odor associated with these methods.

At the federal level, there could be compliance issues with the Resource Conservation and Recovery Act (RCRA), Comprehensive Environmental Response Compensation and Liability Act (CERCLA) and ancillary regulations like Occupation Safety and Health Administration (OSHA). In addition to government enforcement under RCRA and CERCLA, these hazardous waste laws also permit private party suits. Although plant material from cultivation is not considered hazardous, process liquids from extraction or distillation (ethanol, acetone, etc.) are hazardous. Under RCRA, an individual can bring an “imminent and substantial endangerment” citizen suit against anyone generating or storing hazardous waste in a way the presents imminent and substantial endangerment to health or the environment. Under CERCLA, private parties who incur costs for removal or remediation may sue to recover costs from other responsible parties.

At the state level, there could be issues with state agency guidance and state laws. For example, California has multiple state agencies that oversee cannabis and hemp production and disposal. CA Prop 65 mandates warnings for products with certain chemicals, including pesticides, heavy metals and THC. The California Environmental Quality Act (CEQA) requires the evaluation of the environmental impact of runoff or pesticides prior to issuing a cultivation permit. Both environmental impact laws permit a form of private action.

Given the varied and evolving rules and regulation on hemp cultivation, it remains essential for hemp producers to seek guidance and the help of professionals when entering this highly regulated industry.

Cannabis Compliance Testing: Safety vs. Quality

Dr. Markus Roggen is a chemist, professor, cannabis researcher and founder & CEO of Complex Biotech Discovery Ventures (CBDV). Founder & CEO of Ascension Sciences (ASI), Tomas Skrinskas has been at the leading edge of transformative healthcare technologies, including computer assisted surgery, surgical robotics and genetic nanomedicines, for over 15 years.

Leading researchers from the cannabis industry – Dr. Markus Roggen (Complex Biotech Discovery Ventures) and Tomas Skrinskas (Ascension Sciences) – highlight the challenges facing the industry’s current compliance testing standards and the opportunities emerging from the latest developments in nanotechnology and advanced analytical testing. Here are the key insights from the discussion. 

What are the current compliance testing requirements for cannabis products? Are they sufficient in ensuring safety and quality?

In the current landscape, Canada’s compliance testing requirements are clearly laid out in the form of guidance documents. Specifically, for pesticide testing, cannabinoid concentration content in products, heavy metals, etc. Compliance testing can be roughly divided into two categories: 1) establishing the concentrations of wanted compounds, and 2) ensuring that unwanted compounds do not exceed safety limits.

In the first category, cannabinoids and terpenes are quantified. Their presence or absence is not generally forbidden but must stay within limits. For example, for material to be classified as hemp, the THC concentration cannot exceed 0.3 %wt., or a serving of cannabis edible should contain below 5 mg of THC. The second category of compliance testing focuses on pesticides, mold and heavy metals. The regulators have provided a list of substances to test for and set limits on those.

Are those rules sufficient to ensure safety and quality? Safety can only be ensured if all dangerous compounds are known and tested for. Take for example Vitamin E acetate, the substance linked to lung damage in some THC vape consumers and the EVALI outbreak. Prior to the caseload in the Fall of 2019, there were no requirements to test for it. It’s not only additives that are of concern. THC distillates often show THC concentrations of 90% plus 5% other cannabinoids. What are the last 5% of this mixture? Currently, those substances have not been identified. Are they safe? There is no concrete way to determine that.

The aforementioned guidelines have the best intentions, but do not adequately address two key obstacles the industry is currently facing: 1) what happens in practice, and 2) what can easily be audited? Making sure people follow the requirements is the challenge, and it comes down to variability of the tests. Testing has to happen on the final form of the product as well as every “batch,” but there is little guidance on how that is defined. With so much growth happening in the industry, how are these records even tracked and scrutinized?

And finally, there’s the question of quality. How do you define quality? Before establishing quantifiable quality attributes, it can’t be tested.

If compliance testing is insufficient, then why aren’t more cannabis companies testing beyond Health Canada’s requirements?

Compliance testing has always been focused on the end product, THC and CBD levels, and consumer safety. As long as cannabis companies are testing to determine this, doing further testing means added costs to the producer. There is a rush to get cannabis products to the new market because many consumers are eager to buy adult use products such as extracts or edibles, and quality is not the biggest selling point at this very moment.

However, there are unrealized advantages to advanced analytical testing that go beyond Health Canada’s requirements and that offer greater benefits to cannabis producers and product developers. Producers often see testing as an added cost to their production that is forced upon them by the regulators and will only test once the product is near completion. For cannabinoid therapeutics and nutraceuticals, advanced analytical testing is critical for determining the chemical makeup and overall quality of the formulation. This is where contract researchers, such as Ascension Sciences, come in to offer tests for nanoparticle characterization, cannabinoid concentration, dissolution profiles and encapsulation efficiency.

A lack of budget and awareness have prevented cannabis companies from advanced analytical testing. However, testing that goes beyond lawful requirements is an opportunity to save money and resources in the long term. This is where companies, like Complex Biotech Discovery Ventures (CBDV), offer in-process testing that provides a deep characterization and analysis of cannabis samples during every stage of product development. If tests are conducted during production, inefficiencies in the process are revealed and mistakes are spotted early on. For example, testing the spent cannabis plant material after extraction can verify if the extraction actually went through to completion. In another case, testing vape oil before it goes into the vape cartridges and packaging allows producers to detect an unacceptable THC concentration before they incur additional production costs.

Which methods are the most successful for cannabis testing?

The most effective method is the one that best determines the specific data needed to meet the desired product goal. For example, NMR Spectroscopy is paramount in assessing the quality of a cannabis sample and identifying its precise chemical composition.

HPLC (liquid/gas chromatography) is the most precise method for quantifying THC, CBD and other known cannabinoids. However, if a cannabis extractor wants to quickly verify that their oil has fully decarboxylated, then an HPLC test will likely take too long and be too expensive. In this case, IR (Infrared Spectroscopy) offers a faster and more cost-effective means of obtaining the needed data. Therefore, it ultimately depends on the needs of the producer and how well the testing instruments are maintained and operated.

What’s next in analytical testing technology? What are you working on or excited about?

In terms of compliance, regulations to standardize the testing is the hot topic at the moment. For nanotechnology and nanoparticles, the big question now is what is known as the “matrix” of the sample. In other words, what are the cannabinoids, and what else is in the sample that’s changing your results? The R&D team at Ascension Sciences is in the process of developing a standardized method for this to combat the issues mentioned earlier in the interview.

Ascension Sciences is also excited about characterizing nanoparticles over time to determine how cannabinoids are released and how that data can be transferred or made equivalent to consumer experiences. For example, if a formulation with quicker release, faster onset and better bioavailability is found in the lab, product development would be more efficient and effective when compared to other, more anecdotal methods.

At CBDV, the team is working on in-process analytical tools, such as decarboxylation monitoring via IR Spectroscopy and NMR Spectroscopy. CBDV is also looking at quantifying cannabis product quality. The first project currently in motion is to identify and quantify cannabinoids, terpenes, and other compounds present when vaping or smoking a joint using a smoke analyzer. 

A lack of budget and awareness have prevented cannabis companies from testing beyond what’s required by Health Canada. Compliance testing is designed to ensure safety, and for good reason, but it is currently insufficient at determining the quality, consistency and process improvements. As the above factors are necessary for the advancement of cannabis products, this is where further methods, such as advanced analytical testing, should be considered.

Banking Rights in the Hemp Industry

By Jonathan Miller

The hemp industry has experienced and continues to see a surge of growth and awareness nationwide. Following the passage of the 2018 Farm Bill, permanently legalizing the crop and removing hemp from its classification as a controlled substance, consumer demand for hemp and hemp products like CBD have skyrocketed.

Unfortunately, there remain many challenges. Confusion about hemp’s legal status – and the differences between hemp and its intoxicating cousin, marijuana – has too often stymied commerce in the industry, particularly with traditional banking products and merchant services being limited in their availability to those trying to grow their businesses.

This month, we witnessed a breakthrough development. Upon the bipartisan urging of Senate Majority Leader Mitch McConnell and Senator Ron Wyden, four federal banking regulatory agencies – Federal Deposit Insurance Corporation, Office of the Comptroller of the Currency, the Federal Reserve, Financial Crimes Enforcement Network – joined by the Conference of State Bank Supervisors – issued joint guidance confirming the legal status of hemp and the requirements for banks providing financial services to businesses.

Just some of the many CBD products on the market today.

The new guidance achieves many necessary benchmarks integrating hemp and banking, such as no longer requiring banks to file suspicious activity reports for customers solely because they are engaged in the growth or cultivation of hemp in accordance with applicable laws and regulations. Further, the guidance clarifies the difference between hemp businesses and marijuana businesses – adding yet another point of relief to banks concerned with national and state legality.

The hope is that the joint guidance should alleviate any fear of audits or regulatory crackdowns that have slowed financial institution integration with the hemp industry. However, this does not require banks or financial entities to participate in business with hemp companies. Nor does this guidance directly address the legality of hemp-derived CBD commerce.

With all of this in mind, there is still work to be done. Priority #1 is passage of the SAFE Banking Act. This bipartisan legislation, initially focused on providing a green light to marijuana banking in states where pot is legal, was amended to ensure a separate safe harbor for hemp, with far fewer hoops since it is not a controlled substance. It also directs federal financial agencies to provide clear guidance to both banks and other financial institutions – such as credit card companies – that hemp and CBD commerce are legal. The bill was passed overwhelmingly by the House in September and we are hopeful to see full Senate consideration soon.

Banking is one of the key targets that the hemp industry is aiming to secure, as this will allow for an increase in legal hemp business growth and practices. The goal of the U.S. Hemp Roundtable is to provide consumers with safe and legal hemp products along with the knowledge that the companies are meeting the highest standards and complying with national and state law.

US Patent & Trademark Office Issues Guidance for Trademarking CBD Products

By Aaron G. Biros

Last week, the United States Patent and Trademark Office (USPTO) published an Examination Guide to provide further clarity for how they assess the legitimacy of trademarks for cannabis products. For the uninitiated, the 2018 Farm Bill, which President Trump signed into law on December 20, 2018, removed hemp-derived cannabidiol (CBD) from the Controlled Substances Act. In order to register a trademark in the United States, the mark must be used in a lawful setting, meaning that the USPTO does not register trademarks for products that violate federal law- even if it is legal under state law.

In their guidance document, the USPTO identifies the distinction between hemp and other cannabis varieties as the basis for either issuing or refusing a trademark registration. This means that in the trademark application, companies need to specify that the cannabis product is derived from hemp, or cannabis with less than 0.3% THC in dry weight.

The USPTO clarifies that applications for trademarks that involve CBD filed before December 20, 2018 will be refused, but if they amend the filing date to after that date, the registration will be examined. Below is a direct quote from their examination guide clarifying this:

For applications filed before December 20, 2018 that identify goods encompassing CBD or other cannabis products, registration will be refused due to the unlawful use or lack of bona fide intent to use in lawful commerce under the CSA. Such applications did not have a valid basis to support registration at the time of filing because the goods violated federal law. However, because of the enactment of the 2018 Farm Bill, the goods are now potentially lawful if they are derived from “hemp” (i.e., contain less than 0.3% THC). Therefore, the examining attorney will provide such applicants the option of amending the filing date and filing basis of the application to overcome the CSA as a ground of refusal.

The USPTO’s Examination Guide explicitly mentions the authority of the FDA to regulate products derived from cannabis, much like the 2018 Farm Bill’s language. There is still some confusion in the cannabis industry surrounding the marketing and sale of hemp products under FDA regulation.

FDAlogoUnder the Federal Food Drug and Cosmetic Act (FDCA), using a drug in a food or dietary supplement that is currently undergoing clinical trials is illegal (as is the case here- see Epidiolex for an example of CBD being used as an active ingredient in an FDA-approved clinical trial). According to the USPTO, this means that “registration of marks for foods, beverages, dietary supplements, or pet treats containing CBD will still be refused as unlawful under the FDCA, even if derived from hemp, as such goods may not be introduced lawfully into interstate commerce.”

Regarding trademarks for services involving “cannabis and cannabis production,” the USPTO also issued guidance. This section of the Examination Guide pertains to companies applying for a trademark that fall in the category of ancillary services, such as growing supply companies, lighting, nutrients, pest control and packaging, among other service providers. Basically, this section boils down to the same distinction the Farm Bill made between hemp and other varieties of cannabis. An applicant for a trademark needs to make clear their identification of services offered as involving cannabis containing less than 0.3% THC.

For a helpful guide breaking down what this means for cannabis companies pursuing a trademark registration, Christiane Schuman Campbell, partner at Duane Morris LLP, published this client alert about the USPTO’s examination guide.

Health Canada Issues Voluntary Cannabis Recall Guide

By Marguerite Arnold
1 Comment

Last month, Health Canada published a Voluntary Recall Guide to help producers not only stay in compliance but run their operations better. While it will certainly prove to be a critically useful guide for Canadian LPs who are now subject to domestic regulations, it is also a highly useful document for others. Namely, newly legalizing U.S. states and even European countries now looking for guidance on how to shape, structure and regulate their own burgeoning domestic cultivation markets either underway now or about to start.

What Is Of Particular Interest?

While it may sound like a no-brainer, the guide lays out, albeit in very broad strokes, the kinds of procedures all licensed producers should be implementing anyway to efficiently run a compliant business.

It could be considered, on one level, a critical start-up business guide for those still looking for guidance in Canada (as well as elsewhere). Domestically, the document is clearly a handy template, if not something to create checklists from, in setting up a vital and at this point, mandatory part of a compliant cultivation facility in Canada.

The guide also covers not only domestically distributed product but that bound for export.

One of the more intriguing aspects of the guide is also how low tech it is. For example, the guide suggests that a license holder responsible for recall notices, plan on quick response methods that include everything from a self-addressed postcard to an email acknowledgement link.

That said, recalls must be reported to the government exclusively via an email address (no mail drop is listed). And suggestions about media outlets to which to submit recall notices are noticeably digitally heavy. Websites and social media platforms are suggested as the first two options of posting a recall. Posters at retailers is listed dead last.

What is also notable, not to mention commendable, is the inclusion of how to include supply chain partners in recall notices, as well as the mandate to do it in the first place.

Also Of Note

Also excellent is the attempt to begin to set a checklist and process about evaluating both the process of the recall itself and further identification of future best practices.Health Canada also expects companies to show proof of follow up efforts to reach non-responders all along the supply chain.

For example, the report suggests that LPs obtain not only feedback from both their supply chain and consumers involved, but elicit information on how such entities and individuals received the information in the first place. Further, the volume of responses (especially from end consumers) or lack thereof should be examined specifically to understand how effective the outreach effort actually was in reaching its target audience.

This is especially important because Health Canada also expects companies to show proof of follow up efforts to reach non-responders all along the supply chain.

Regulatory Reporting Guidelines

One of the reasons that this guide is so useful is that Health Canada also expects to receive full written reports touching upon all of the issues it lays out within 30 days of the recall announcement itself.

In turn, this is also a clear attempt to begin to start to document quality controls and attempts to correct the same quickly in an industry still plagued by product quality issues, particularly at home, but with an eye to overseas markets.

As such, it will also prove invaluable to other entities, far beyond Canadian LPs involved in the process this document lays out. Namely, it is a good comprehensive, but easy to follow and generally applicable guide for new states (in the case of the US) if not national governments in Europe and beyond who are now starting to look at regulating their own burgeoning industries from the ground up.

Quality Controls and Medical Cannabis: What We Can Learn from Pharma

By Dr. Ginette M. Collazo
1 Comment

When we discuss growing and producing medical cannabis, we must think of it as a medicine. By definition, it is a substance intended to assist you with a medical condition, to help you feel better and not harm you. Drugs produced in the pharmaceutical industry go through extensive quality controls to ensure a level of safety for the consumer or patient. Yet when we talk process and quality controls in medical cannabis production, there is still a lot to learn.

Are we waiting for the wake-up call? Well, ring! Recently Health Canada, the regulatory body overseeing Canada’s medical cannabis market, decided that “It will begin random testing of medical marijuana products to check for the presence of banned pesticides after product recalls affecting nearly 25,000 customers led to reports of illnesses and the possibility of a class action lawsuit.”

Proper quality controls help protect businesses from unforeseen issues like those massive recalls in Canada. These can assure that the product is safe (won’t harm you), has integrity (free of contamination), and that the product is what it says it is (identity). To achieve this important goal, we must have robust systems that will guarantee product quality. Why is this important? Quality controls can ensure a safer and more consistent product, helping build patient and consumer trust and brand loyalty, preventing a public relations nightmare like a recall due to pesticide contamination.

Food processing and sanitation
Product recalls due to manufacturing errors in sanitation cause mistrust among consumers.

The FDA, among other regulatory bodies, has established excellent guidelines to implement these controls. So there is a lot we can learn from the pharmaceutical industry and that FDA guidance regarding quality controls and assurance. After all, we are all interested in the same thing: a safe and effective product.

So, let’s take a look at some of the controls included in the CFR (Code of Federal Regulation), Part 211 , which include Good Manufacturing Practices (GMPs) for finished products, and how you can implement them in the growing business of growing cannabis.

  1. Personnel selection and training: The GMPs establish that “Each person engaged in the manufacture, processing, packing, or holding of a drug product shall have education, training… to enable that person to perform the assigned functions.” These include the creation of specific curricula per position and the establishment of requirements for specialized tasks. We all want to be successful so training, in this case, is what we call the vaccine for mistakes.
  2. Facilities: “Any building or buildings used in the manufacture, processing, packing, or holding of a drug product shall be of suitable size, construction, and location to facilitate cleaning, maintenance, and proper operations.” This requirement includes segregation of spaces to avoid cross-contamination, housekeeping, the cleaning process and detergent types, material storage conditions, humidity levels, temperature, water, and even ventilation requirements to prevent contamination with microorganisms. All with the intention of protecting the product.
  3. Pest control: “There shall be written procedures for the use of suitable rodenticides, insecticides, fungicides, fumigating agents, and cleaning and sanitizing agents. Such written procedures shall be designed to prevent the contamination of equipment, components, drug product containers, closures, packaging, labeling materials, or drug products and shall be followed.” There have been many issues pertaining this requirement. In 2010, Johnson & Johnson received many complaints claiming that the product had a musty, moldy odor. Later, the firm identified the cause of the odor to be a chemical, called 2, 4, 6-Tribromoanisole or TBA; a pesticide used to treat wooden pallets. One of the specific requirements of this section is to avoid the use of wooden pallets, but if you decide to use them, the method of sterilization by heat treatment seems like the only safe option for sterilizing wooden pallets and wood cases.
  4. Equipment/Instrumentation: “Equipment used in the manufacture, processing, packing, or holding of a drug product shall be of appropriate design, adequate size, and suitably located to facilitate operations for its intended use and its cleaning and maintenance.” The intention is to not alter the safety, identity, strength, quality, or purity of the drug product beyond the official or other established requirements. What would happen if lubricants/coolants or any other substance, not intended to be part of the product, comes in contact with the product?
  5. Procedures and documentation: “There shall be written procedures for production and process control designed to assure that the drug products have the identity, strength, quality, and purity they purport or are represented to possess. Such procedures shall include all requirements of this subpart. These written procedures, including any changes, shall be drafted, reviewed, and approved. When we have followable, well written, clear, and specific procedures, we avoid possible errors that can get us in trouble.
  6. Defects Investigation: “Written production and process control procedures shall be followed in the execution of the various production and process control functions and shall be documented at the time of performance. Any deviation from the written procedures shall be recorded and justified.” We want to be successful, for that we need to learn from failures, understanding the root causes, correcting and preventing re-occurrence is what will keep you competitive. As you can see this requirement is essential for, quality, business and to evidence that such deviations did not adulterate the product.
  7. Process controls: Besides written procedures and deviations management, operation controls are pivotal in guaranteeing the quality as well as complete documentation of your process. These controls will vary depending on your technology and your product. If you do alcohol (ethanol) extraction, for example,  you want to keep an eye on the temperature, dissolution time, and even have color standards to be able to quickly and correctly identify possible abnormalities, while you can still correct the mistake. In-process product testing will allow you to monitor “performance of those manufacturing processes that may be responsible for causing variability in the characteristics of in-process material and the final product.”

Regardless of federal regulatory guidance, quality controls can be that one factor which can make or break your business. Why re-invent the wheel?
