What to Expect When Opening a Lab in a New State
Michael Kahn, Founder & CEO, MCR Labs
Kahn explores the lab’s role int he cannabis industry, the importance of knowing and understand state regulations and lessons for growing your lab while maintaining quality.
Few people will disagree that financial compliance isn’t the most exciting topic within the cannabis industry. But compliance is, and always will be, the engine grease to the legal cannabis market. Cannabis operators have the arduous task of dealing with multiple layers of compliance, both operational (maintaining and adhering to regulations enforced by the state licensing board) and financial. These compliance measures include managing everything from seed-to-sale systems for all plant-related activity to on-site requirements like facility access points and alarms systems to name a few.
With complex compliance requirements for the business, the last thing cannabis operators want to think about is financial compliance. We created Confia on this notion. Just as cannabis regulators impose the tracking of plants through the supply chain via a seed-to-sale system, we have developed a storyboard similarly designed to follow the money, which is the equivalent of a transaction-to-deposit system.
Having experience in regulatory technology, artificial intelligence and machine learning, we’ve been fortunate enough to work with some of the world’s largest banks across multiple countries. This experience has afforded us the luxury of working alongside regulators, chief compliance officers and chief risk officers, understanding how risk is perceived by financial institutions and how it ought to be mitigated. It was this access and knowledge that allowed us to effectively reform, enhance and improve the antiquated BSA programs with a technology-enabled process. Leveraging technology is a necessity, almost a requirement, for the cannabis industry as legalization nears and banking access begins to broaden.
Jamming cannabis requirements into an existing BSA program doesn’t scale well. BSA programs are very manual, descriptive and process oriented. So, we’ve taken our prior experience and success in banking to form Confia, distilling the complexities and simplifying the deliverables surrounding cannabis banking compliance. To best articulate cannabis banking requirements, I break it down into three pillars.
Pillar One: KYC-Enhanced Due Diligence
The first pillar is the client-onboarding bucket or KYC – Know Your Customer. In the complex world of cannabis banking, banks must know and understand their clients to great depths. It’s not enough to simply know that the client exists; you also have to understand whether or not that client could be a potential risk to the bank, and one step further, the financial system. Cannabis is a high-risk industry, so the KYC requirement is escalated to a deeper diligence and review, called Enhanced Due Diligence (EDD).
Cannabis is a high-risk industry so extra due diligence is needed
Banks need to know and understand their customers’ story, and all the key parties (officers, directors, and those with key decision-making powers or access to the bank accounts) within that organization. This includes reviewing personal, business, and legal history – not to mention watchlists and negative news presence. An initial onboarding review must then be followed with daily screening and monitoring of all watchlists and adverse media. Typically, banks do KYC refreshes every three years. In cannabis, a full refresh should be done annually with the daily monitoring systems in place.
The high-risk nature of the industry also requires a level of diligence on all parties to a transaction, even if one of the parties, whether a payer or recipient, is not a client of your bank. Unlike traditional banking sectors, reliance on other banks’ KYC programs is far less defensible in the cannabis industry.
Pillar Two: Transactional Monitoring & Detection
Tracking and monitoring the actual financial transactions comprises the second pillar required for cannabis banking. At Confia, we have focused on streamlining processes, so the cannabis operator can seamlessly support the compliance obligation for every transaction. A bank must demonstrate supporting documentation for every cannabis transaction, and gathering such information is a large undertaking in and of itself and can pose future issues if not done properly, see the pitfalls for lack of compliance. Banks are obligated to understand the nature and reason for each transaction, the source of funds, ensure cannabis licenses are in good standing for all parties, and collect evidence such as accounting records and seed-to-sale data.
Core to transaction monitoring in the traditional sense, is the overarching support through anomaly detection. Relying on information is important, but testing those inputs keeps everyone honest. It is important to evaluate transactions from a holistic point of view relative to peers and relative to the general contents of a transaction. This anomaly detection layer is your last line of defense, and as new information is collected, it continues to refine itself.
Pillar Three: Filing and Reporting Requirements
The third component to compliant cannabis banking is regulatory filing and reporting. Once a client is onboarded, the account requires an initial suspicious activity report or SAR-Initial within 30 days of that client being approved by the bank. Then, a report must be filed every 90 days after that for all the transactions of that cannabis operator. Banks must file the SAR-Initial and the Continuing-SAR reports for each cannabis client they have.
The high-risk nature of the industry requires a level of diligence on all parties to a transaction
Solutions like Confia automate the filing process and support the filing with transactional data evidenced on our distributed ledger of record. This provides immutable audibility and simplifies the process for all parties involved.
Compliance Requirements After US Legalization
The anticipation of federal legalization and banking reform bills has many operators hoping for easier banking. Yet, in my opinion, regulatory oversight and audits will likely increase after such reform or legalization. As other financial institutions start to support cannabis, it will inadvertently create greater opportunity and expose the financial system to nefarious or illegitimate transaction activity. This is why cannabis banking will be carefully monitored by regulators, and more so, why banks will be slow and pragmatic in standing up their internal cannabis banking programs. Some banks may forever avoid the cannabis industry due to the known pitfalls of an industry specific program, while others may simply mitigate the possible exposure to reputational risk.
Choose Wisely: Pitfalls for Lack of Compliance
Financial compliance is the responsibility and duty of the banks, but the real losers and result of non-compliance always fall on the cannabis operators. Regulatory action against an institution may result in the bank shutting down its cannabis program or may require them to complete a remediation of all their cannabis transactions for a certain period from its clients. At the end of the day, regardless of action, the cannabis operator is the one being punished. Operators either lose their bank account and have business massively disrupted, or they are asked to provide all the compliance docs for a historic period, which is a huge undertaking and operational distraction, ultimately impacting business and productivity. So, choose your banking partner wisely.
Summarizing Key Banking Requirements
In summary, banking in the cannabis industry will undoubtedly remain a high-risk industry, with or without legalization. Although banking opportunities may expand as US policies change, there will be continued compliance and regulatory requirements for the foreseeable future.
Onboarding and ongoing screening are critical
Evidence for every transaction is a significant portion of compliance and must not be dismissed
Evaluating activity with broader strokes is essential in mitigating against money laundering
Managing the staggered filing timelines and due dates for each client
Compliance is the most crucial factor in cannabis banking at this point. It cannot be overlooked or taken for granted. Cannabis operators must take an active role in evaluating the compliance programs of their financial providers. To open a bank account is one thing, but the consideration and effort that goes into keeping a bank account is the difference that will protect your business in the long run.
Earlier this year, the Colorado Department of Public Health and Environment (CDPHE) announced a plan to introduce new testing rules for the state’s growing hemp industry. Under the new regulations, hemp products must be tested for residual solvents, heavy metals and pesticides, in addition to making sure they contain less than 0.3% THC.
The CDPHE are planning on a gradual rollout to prevent any supply chain issues or a lab testing bottleneck, similar to what we’ve seen in other states launching new testing requirements in years past, such as Arizona or California. Well, the Colorado rollout appears to be hitting similar snags and because of supply chain issues related to instruments and consumables in laboratories, the implementation of those testing rules is somewhat delayed. What was originally supposed to be implemented over the summer was pushed back to an October 1 deadline, and that deadline has now been pushed back to 2022.
The pesticide testing list to be implemented January 1, 2022
As a result of supply chain shortages and the learning curve to test for such a wide range of pesticides, Colorado is opening hemp testing to out-of-state labs in an effort to stay on schedule with the rollout. Dillon Burns, lab manager at InfiniteCAL, a cannabis testing company with locations in California and Michigan, just completed an audit with the CDPHE in their work to get certified and start conducting hemp testing for businesses in Colorado.
Burns says they’re well-acquainted with the list of pesticides because of how similar the list is to California’s requirements. “For the pesticide testing rules that were supposed to go into effect on August 1st, it’s basically the same list as California just with slightly different action levels,” says Burns. “I would say these action limits are generally stricter – they have much lower LOQs [limits of quantification].”
The pesticide testing list (continued) to be implemented January 1, 2022
Come January 1, 2022, they are expecting an additional 40 pesticides to be required under the new rules. “But currently, it’s still unclear when these regulations will actually go into effect,” says Burns. The full pesticide testing list is currently slated to be implemented on April 1, 2022.
The supply chain issues referenced above have a lot to do with what the state is asking labs to test for. Previously, most of the pesticides tested for under Colorado’s adult use and medical cannabis programs could be analyzed with an LC/MS. A handful of pesticides on the new list do require GC/MS, says Burns. It’s entirely possible that a lot of labs in Colorado just don’t have a GC/MS or are in the process of training staff and developing methods for using the new instrument. “Cleanliness of these instruments is such a priority that it takes time to acquire the right skill set for it,” says Burns.
Dillon Burns, Lab Manager at InfiniteCAL
The new testing rollout isn’t just another compliance hurdle for the cannabis industry; these rules are about protecting public health. Dillon Burns said he’s seen hiccups in California with the amount of new hemp farmers getting into the space. “The hemp products we’ve tested in California often fail for pesticides,” says Burns. It’s a lot easier in most states to get a license for growing hemp than it would be for growing adult use cannabis. “You’ll see a lot more novice growers getting into hemp farming without a background in it. They’ll fail for things they just haven’t considered, like environmental drift. We see a lot of fails in CA. Hemp is bioaccumulating so it presents a lot of problems. If they’re not required to look for it, they weren’t monitoring it.”
When asked how the market might react to the new rules, Burns was confident that Colorado knows what they’re doing. “I don’t anticipate that [a testing bottleneck] happening here. The regulators are reasonable, supportive of the industry and opening it up to out-of-state labs should help in preventing that.”
Let’s just say it. There is an undeniable chaos in the cannabis industry. It doesn’t matter if you’re a big or small operator, it’s likely that you don’t have a documented system for creating and managing ever-changing SOPs or for consistently training all employees on the most current versions of those SOPs. This chaos is often the result of rapid growth, mergers and acquisitions, and the ever-present turnover in our industry. When department leadership changes, and it often does, established policies and procedures are often left behind. In some cases, this is a positive sign of growth. As a company outgrows SOPs and as it develops more sophisticated ways to cultivate, extract, process, manufacture, package and sell cannabis and cannabis products, inevitably, the old ways of doing business need to be replaced. For those operators who have prioritized operational excellence, whether they want to position their company for new investment, merger or acquisition, or just want to create a consistent and standardized, branded product, it’s critical to get control of SOPs, training and documentation.
By standardizing and documenting safety procedures, manufacturers mitigate the risk of cannabis-specific concerns
As with most big goals, to obtain operational excellence, you need to break the goal into manageable steps. Assuming you have accessible quality policies and procedures in place, properly training employees when they first start work and on an ongoing basis as policies and procedures change is the number one key to successful operations. When employees know how to do their job and understand what is expected of them, they are positioned for success. When employees are successful, it follows that the company will also be successful. Documenting operations is a second important step in obtaining operational excellence. While training and documentation appear to be different, in best-practice organizations, they are inextricably linked.
One Set of SOPs
Those of us who have been in the cannabis industry for a while have experienced firsthand or heard stories of facility staff working off of two sets of SOPs. There’s the set of SOPs that are printed or digitally available for the regulators, let’s call them the “ideal” set, and then there are the SOPs that actually get implemented on a day-to-day basis. While this is common, it’s risky and undermines the foundation of operational excellence. Employees often know there are two sets of SOPs. Whether they express it or not, many are uncomfortable with the intentional or unintentional deception. When regulators arrive, will they have to bend the truth or even lie about daily operations? Taking the time to establish and implement one set of approved SOPs that is compliant with both external regulations and internal standards is good for employee morale, productivity and ultimately, profits.
What’s the best way to get control of a facility’s SOPs? Again, break it into manageable steps:
First, task someone with reviewing all SOPs that are floating around. Determine if any are non-compliant, which ones need to be tossed and which ones need to be revised so they work for the company as well as outside regulatory authorities.
At a minimum, establish a two-person team to draft, review, publish and distribute the final SOPs. Ensure that at least one member of the team has management level authority. Assign that employee the responsibility of reviewing the SOPs before “publication” and distribution.
Archive, delete, or actually throw away outdated or non-compliant SOPs
Revise or create new best-practice SOPs that are in compliance with external regulations and internal standards
Establish a system to update SOPs when external regulations and internal standards change
Use a naming convention that distinguishes draft SOPs from final SOPs, for example, “Post-Harvest Procedure, FINAL”
Inform employees that they will be retrained on the new SOPs and that approved SOPs will always have the word “Final” in the title
Store the final SOPs in an easily accessible location and give employees access, not only during training, but on an ongoing basis
Centralized Repository for Final SOPs
Storing final, approved SOPs in one easily accessible, centralized location and giving employees access sounds simple, but again, this is the cannabis industry, so this often doesn’t happen. Many of us have or are currently working for an organization that stores SOPs in multiple places. Each department may have its own way of updating, disseminating and storing SOPs. Some SOPs are stored in a printed binder stuffed in a drawer or left on a bottom shelf. Others are stored digitally. Some use both systems, which creates confusion. Who knows if the digital versions or the printed versions are the most current? Surely someone knows, but often the front-line staff do not.“Once you’ve established a single set of compliant SOPs and have stored them in one accessible location, it’s time to train your employees.”
Establishing a centralized repository for final, approved SOPs is the foundation of operational excellence. It lets employees know that operations are organized and controlled, and it reassures regulatory authorities and external stakeholders—think insurers, bankers, investors—that the company prioritizes compliance and organization. And external stakeholders who believe that an organization is proactive and well-run tend to be more forgiving when the inevitable missteps occur. Companies that are organized, have effective training systems, regularly conduct internal audits to identify potential issues and take identifiable action steps when necessary to remediate issues, receive fewer deficiency notices, violations and fines than their less organized competitors.
Train Employees
Many states require cannabis operators to provide a specific number of training hours prior to an employee beginning work, and a specific number of continuing and refresher training hours annually. Once you’ve established a single set of compliant SOPs and have stored them in one accessible location, it’s time to train your employees. To do so, set clear expectations and decide who is responsible for what. Is the HR manager responsible for initial onboarding and training? Are department managers responsible for ongoing and annual training? Create a training responsibility chart that works best for your company; write it down and share with all stakeholders.
Documenting all key areas of operation on a recurring basis will help you keep track of a large facility and workforce
The next step is to figure out how to train your employees. Individuals have different learning styles, so ideally, you’ll offer multiple ways for them to master the requirements of their position. Assign written materials and if possible, attach short videos showing the best way to complete a task. Follow up with a quiz to determine comprehension and a conversation with a department lead or manager to answer questions and review the key take-aways. Ideally, the department manager or lead employee will work with the employee until they are competent and comfortable taking on new assigned tasks and responsibilities.
Sum It Up
Operational excellence begins with:
Knowledge of and access to current external rules and regulations and internal standards
One set of approved and easily accessible policies and SOPs that comply with both external and internal standards
An initial training system with clearly assigned roles, responsibilities, and goals
An ongoing training system with clearly assigned roles, responsibilities, and goals
Systems to:
Test knowledge before employees begin unsupervised work
Stay up-to-date with all changes to external rules and regulations and internal standards
Control policy and SOP revision process
Inform all stakeholders when policies and SOPs change
Test that employees understand new standards
Document all key areas of operation on a recurring basis
Address deficiencies and evaluate whether SOP revisions are warranted
Document and implement necessary remediation when necessary
For those of you rolling your eyes and thinking you don’t have time for this, ask yourself, “Can you afford not to?”
For those of you committed to operational excellence and doing what it takes to get there, congratulations on being a visionary leader. Your efforts will pay dividends for your own company and will help the cannabis industry grow into a well-respected, profitable industry that improves lives.
ACS Laboratory, a cannabis and hemp testing lab based outside of Tampa Bay, Florida, announced the launch of their “Tested Safe Certified Seal” program. The program is designed to help raise standards and put more consumer trust in safe, tested products.
The “Tested Safe Certified Seal” on a hemp oil product
ACS Laboratory is an ISO 17025-accredited and DEA-licensed cannabis testing company founded in 2008. Last year they were certified by the Florida Department of Health to perform cannabis testing for state-licensed cannabis companies. In addition, the company acquired Botanica Testing, Inc. in 2020, adding more than 500 hemp and CBD clients to their portfolio. They now perform hemp testing for clients in more than 44 states.
The “Tested Safe Certified Seal” program allows companies to adorn their products with the trademarked seal following testing, informing consumers that their product has met safety standards and a full panel of compliance tests. “Unlike a mandated QR code that links to a Certificate of Analysis (COA) with detailed test results, the Seal shows visual proof at a glance that consumers can trust a brand,” reads the press release.
The program is also endorsed by the American Cannabinoid Association (ACA). “It is exciting to see our industry legally providing cannabis and cannabis-derived products on a commercial scale,” says Matthew Guenther, founder of the ACA. “As with any consumer product, safety and quality control remain our absolute priority.”
To earn the seal, companies send their products to the ACS lab for a full panel of safety and potency tests. ACS has a scope of services that includes: potency testing for 21 cannabinoids, 38 terpene profiles, 42 residual solvents, screening for 105 pesticides, moisture content, water activity, microbiology panels, heavy metals screening, flavonoid testing for 16 profiles, micronutrient testing, mycotoxins, Vitamin E acetate, shelf life & stability, plant regulators (PGRS), PAH testing and Pharmacokinetic Studies (PK) aka human trials.
The NIST is an organization under the U.S. Department of Commerce that promotes innovation through standards, technology and advancing science. The NIST’s CannaQAP platform works with cannabis labs to help improve competence in analytical science and standardization.
The program requires participating labs to conduct exercises that help inform the NIST about current industry standards and capabilities for hemp and cannabis testing. One of the goals of the program is aiding in the design and characterization of cannabis reference materials.
Kaycha Labs took part in two exercises for the CannaQAP study. Exercise 1 included testing for potency with 17 cannabinoids in hemp oil and Exercise 2 included potency, heavy metals and moisture content testing in plant materials.
Chris Martinez, president of Kaycha Labs, says the program can benefit the entire industry when it comes to regulatory compliance testing. “As a leading cannabis lab company with a network of labs in multiple states, it is imperative we demonstrate that our labs apply compliant and consistent testing methodologies,” says Martinez. “Assuring all industry participants, including State and Federal government regulators, that precise and consistent testing data is the norm will benefit the entire industry.”
Kaycha Labs, while based in Fort Lauderdale, actually has cannabis testing labs in California, Colorado, Florida, Massachusetts, Nevada, Oklahoma, Oregon and Tennessee, making them an ideal candidate for CannaQAP.
Exercise 1 has been completed in its entirety and published here. Exercise 2 has completed the participation and data submission legs of the study and NIST is preparing it for publication. On their website, it says that announcements about their upcoming Exercise 3 are coming soon.
Change control, when it comes to quality management systems in manufacturing, processing and producing products such as cannabis edibles or vape pens, is a process where changes to a product or production line are introduced in a controlled and coordinated manner. The purpose of change control process management is to reduce the possibility of unneeded changes disrupting a system, introducing errors or increasing costs unnecessarily.
ASTM International, the international standards development organization, is developing a new standard guide that will cover change control process management for the cannabis and hemp market. The guide is being developed through the D37 cannabis committee.
The WK77590 guide will establish a standardized method for change control process management for cannabis companies so that they can document and track important decisions in manufacturing and quality systems.
For example, an edibles manufacturer would utilize change control process management if they want to use a different type of processing equipment or introduce a new shape or design of their product. Without change control process management, that edibles producer might switch to a new piece of processing equipment without knowing that it requires more energy or uses different raw materials, thus making production unexpectedly more expensive.
While that’s a very cursory example, the premise is simple: Before you undergo a change to your process, plan it out, analyze it, review it, test it out, implement it and make sure it works.
Change control process management can often be summarized in six steps:
Change control is designed to coordinate changes to manufacturing so they don’t disrupt a process.
Plan/Scope
Assess/Analyze
Review/Approval
Build/Test
Implement
Close
Maribel Colón, quality assurance consultant and vice chair of the ASTM subcommittee on cannabis quality management systems, says producers and testing labs will benefit the most from the guide. “As the cannabis industry grows, the quality, expectations, and control challenges grow within,” says Colón. “The creation and implementation of this standard guide will increase cannabis business efficiency and minimize risk, time, and potential cost of poorly managed changes.”
According to a press release, ASTM International is open to collaboration on this as well. Specifically, they are looking for professionals with change control who might be interested in helping advance and develop this guide.
On August 11, PathogenDx announced that they received an AOAC Performance Tested Methods Certificate for their QuantX total yeast and mold test. Six days later, on August 17, Medicinal Genomics announced that AOAC approved their PathoSEEK 5-Color Aspergillus Multiplex Assays under the same AOAC Performance Tested Methods program.
Both assays are specifically designed with cannabis and hemp testing in mind and designed to expedite and simplify microbiological testing. PathogenDx’s QuantX quantifies the total amount of yeast and mold in a sample while also measuring against safety standards.
In addition to the total yeast and mold count test, PathogenDx has also introduced a 96-well plate, improved sample preparation and new data reporting with a custom reporting portal for compliance testing.
The Medicinal Genomics platform can detect four species, including A. flavus, A. fumigatus, A. niger, and A. terreus in both flower and infused edibles. The PathoSEEK microbial testing platform uses a PCR-based assay and provides an internal plant DNA control for every reaction.
This technique verifies the performance of the assay when detecting pathogens, allegedly minimizing false negative results commonly due to set up errors and experimental conditions.
AOAC International is a standards organization that works in the cannabis testing space through their CASP program to evaluate and approve standard testing methods for the industry.
Cross Contamination – noun – “inadvertent transfer of bacteria or other contaminants from one surface, substance, etc., to another especially because of unsanitary handling procedures. – (Mariam Webster, 2021). Cross contamination is not a new concept in the clinical and food lab industries; many facilities have significant design aspects as well as SOPs to deliver the least amount of contaminants into the lab setting. For cannabis labs, however, often the exponential growth leads to a circumstance where the lab simply isn’t large enough for the number of samples processed and number of analytical instruments and personnel needed to process them. Cross contamination for cannabis labs can mean delayed results, heightened occurrences of false positives, and ultimately lost customers – why would you pay for analysis of your clean product in a dirty facility? The following steps can save you the headaches associated with cross contamination:
Wash (and dry) your hands properly
Flash back to early pandemic times when the Tik Tok “Ghen Co Vy” hand washing song was the hotness – we had little to no idea that the disease would be fueled mostly by aerosol transmission, but the premise is the same, good hand hygiene is good to reduce cross contamination. Hands are often the source of bacteria, both resident (here for the long haul; attached to your hands) and transient (easy to remove; just passing through), as they come into contact with surfaces from the bathroom to the pipettor daily (Robinson et al, 2016). Glove use coupled with adequate hand washing are good practices to reduce cross contamination from personnel to a product sample. Additionally, the type of hand drying technique can reduce the microbial load on the bathroom floors and, subsequently tracked into the lab. A 2013 study demonstrated almost double the contamination from air blade technology versus using a paper towel to dry your hands (Margas et al, 2013).
Design Your Lab for Separation
Microbes are migratory. In fact, E. coli can travel at speeds up to 15 body lengths per second. Compared to the fastest Olympians running the 4X100m relay, with an average speed of 35 feet per second or 6 body lengths, this bacterium is a gold medal winner, but we don’t want that in the lab setting (Milo and Phillips, 2021). New lab design keeps this idea of bacterial travel in mind, but for those labs without a new build, steps can be made to prevent contamination:
Try to keep traffic flow moving in one direction. Retracing steps can lead to contamination of a previous work station
Use separate equipment (e.g. cabinets, pipettes) for each process/step
Separate pre- and post-pcr areas
Physical separation – use different rooms, add walls, partitions, etc.
Establish, Train and Adhere to SOPs
Design SOPs that include everything- from hygiene to test procedures and sanitation.
High turnover for personnel in labs causes myriad issues. It doesn’t take long for a lab that is buttoned up with cohesive workflows to become a willy-nilly hodgepodge of poor lab practices. A lack of codified Standard Operating Procedures (SOPs) can lead to a lab rife with contaminants and no clear way to troubleshoot the issue. Labs should design strict SOPs that include everything from hand hygiene to test procedures and sanitation. Written SOPs, according to the WHO, should be available at all work stations in their most recent version in order to reduce biased results from testing (WHO, 2009). These SOPs should be relayed to each new employee and training on updated SOPs should be conducted on an ongoing basis. According to Sutton, 2010, laboratory SOPs can be broken down into the following categories:
Quality requirements
Media
Cultures
Equipment
Training
Sample handling
Lab operations
Testing methodology
Data handling/reporting/archiving
Investigations
Establish Controls and Monitor Results

It may be difficult for labs to keep tabs on positivity and fail rates, but these are important aspects of a QC regimen. For microbiological analysis, labs should use an internal positive control to validate that 1) the method is working properly and 2) positives are a result of target analytes found in the target matrix, not an internal lab contamination strain. Positive controls can be an organism of choice, such as Salmonella Tranoroa, and can be tagged with a marker, such as Green Fluorescent Protein in order to differentiate the control strain. These controls will allow a lab tech to discriminate between a naturally contaminated specimen vs. a positive as a result of cross-contamination.
Labs should, in addition to having good QC practices, keep track of fail rates and positivity rates. This can be done as total lab results by analysis, but also can be broken down into customers. For instance, a lab fail rate for pesticides averages 4% for dried flower samples. If, during a given period of review, this rate jumps past 6% or falls below 2%, their may be an issue with instrumentation, personnel or the product itself. Once contamination is ruled out, labs can then present evidence of spikes in fail rates to growers who can then remediate in their own facilities. These efforts in concert will inherently drive down fail rates, increase lab capacity and efficiency, and result in cost savings for all parties associated.
Continuous Improvement is the Key
Cannabis testing labs are, compared to their food and clinical counterparts, relatively new. The lack of consistent state and federal regulation coupled with unfathomable growth each year, means many labs have been in the “build the plane as you fly” mode. As the lab environment matures, simple QC, SOP and hygiene changes can make an incremental differences and drive improvements for labs as well as growers and manufacturers they support. Lab management can, and should, take steps to reduce cross contamination, increase efficiency and lower costs; The first step is always the hardest, but continuous improvement cannot begin until it has been taken.

As sales of Delta 8 increase, hemp and cannabis industry infighting increases right along with it. Some hemp leaders say they object to Delta 8 simply because it’s intoxicating: “Hemp is nourishing….hemp is not intoxicating,” the president of the U.S. Hemp Authority President told Hemp Grower (apparently cannabinoids can only be one or the other). Others claim that Delta 8 itself is unsafe: “Very little is known about the health effects of Delta 8,” warned the media relations director for the National Cannabis Industry Association. The U.S. Cannabis Council called Delta 8’s growing popularity “a rapidly expanding crisis” in a report that includes the heading “The Health Risks of Delta-8 THC” and claims Delta 8 “presents a public health risk of potentially wider impact than the vape crisis.”
As a cannabis and hemp industry veteran and a long-time maker of numerous hemp-derived formulations (including Delta 8 products) I have to ask: who exactly is Delta 8 a crisis for, and why? I agree that we need to address the legitimate issues with Delta 8 manufacturing and create regulatory oversight that ensures consumer safety. But some Delta 8 critics may be more concerned with their own bottom line than with protecting public health. No one wants another vaping crisis, but demonizing a newly popular cannabinoid or trying to get it banned doesn’t solve the problem of an unregulated space—and it won’t end the demand for Delta 8, either.
The chemical structure of Delta 8 THC.
John Kagia of New Frontier Data points out that the Delta 8 boom is “a phenomenon that has taken the industry quite by storm”—and while that storm’s rising tide saved many hemp farmers from financial ruin, it has not lifted every boat. Some cannabis leaders consider Delta 8 an incursion into “their” market. Indeed, Delta 8 can be sold in some states where cannabis remains illegal: “Unregulated Delta 8 risks becoming a competitive threat to [cannabis companies’] existing offerings, sold in states they can’t get into,” reported Tiffany Kary at the Chicago Tribune. But the threat here for cannabis operators isn’t Delta 8: it’s Prohibition. In states where cannabis is illegal, Delta 8 (which is remarkably similar in molecular structure to its federally illegal chemical cousin Delta 9) is being purchased as an alternative. Rather than villainizing a cannabinoid, let’s address retrograde, reactionary state legislatures that refuse to listen to the will of their constituents, and outdated federal laws that equate THC with heroin.
Many see Delta 8 as a threat to the licensed cannabis industry’s profit margins, not only because it can be sold in prohibition states, but because its unregulated status makes it far easier and cheaper to make and sell. Cannabis companies have to navigate an overwhelming and burdensome maze of regulatory red tape to maintain compliance, so industry-wide frustration with the total lack of oversight for Delta 8 is both understandable and justified. But calling for statewide bans on a product that competes with yours is not the solution. That’s not how markets work. (Of all people, cannabis industry professionals should know that banning cannabinoids doesn’t make them go away.) Regulating Delta 8 manufacturers and requiring rigorous product testing are reality-based measures that will make the playing field fairer for cannabis while also safeguarding public health. In the meantime, we can strongly encourage Delta 8 consumers to seek out products made by ethical operators that are transparent about their manufacturing process and provide third-party testing results—the exact same protocol we recommend for buying CBD.

The safety of Delta 8 products is another legitimate concern that’s unfortunately been distorted. Some alarmist headlines seem to equate the actual cannabinoid itself with hazardous material. One East Coast CBD manufacturer issued a press release announcing “a warning for consumers and manufacturers about potentially harmful chemicals within Delta 8 THC” with the cable-newsworthy headline “Dangerous Delta 8?” Smearing Delta 8 as an inherent health menace is both misleading and unhelpful. As Rick Trojan, vice president of the board of directors of the Hemp Industries Association points out, “Cannabinoids themselves have never in the history of humanity caused a death by themselves.” Once again, the problem here isn’t the actual cannabinoid: it’s the lack of regulation that allows Delta 8 products to be produced with no oversight or testing. But given Delta 8’s widespread popularity, short-sighted bans like the ones that have been passed in 17 different states will only increase the risk to public health. Retailers nationwide sold at least $10 million worth of Delta 8 products last year. I guarantee that demand will continue, and that these bans will simply empower an illegal market full of bad actors.
Finally, I remain shocked at the contempt aimed at Delta 8 because it’s psychoactive, and at those who consume it for just “wanting a cheap high.” As with all cannabinoids, we need more clinical research into Delta 8’s properties—but the research we do have indicates that Delta 8 actually has therapeutic properties very similar to Delta 9 THC, just with less psychoactivity. Anecdotal reports indicate that Delta 8 offers many of the health benefits of Delta 9 (help with sleep problems, stress, and pain management) without THC’s less-enjoyable side effects, like paranoia. As cannabis specialist and medical doctor Peter Grinspoon told Insider, “I can’t tell you how many patients I have who say, ‘I’d love to use medical cannabis instead of opiates for pain, except it makes me anxious.’ Delta-8 might be a very good option for people like that.” Believe it or not, there are plenty of people who are using Delta 8 for its therapeutic effects—which, in a nation where 136 citizens die from opioid overdoses daily, I think should be encouraged rather than derided.
With more than 140 known cannabinoids, it makes no sense for us as an industry to brand some of them as “bad” and others as “good.” Are we going to have these tugs-of-war and calls for bans over every single cannabinoid that becomes popular? Instead of arguing amongst ourselves, we could instead focus our efforts on legalizing all of these plant compounds, studying them to determine their capabilities, and creating standardized, evidence-based regulations and testing regimens to ensure consumer safety and adult use. Delta 8 is popular because it serves a need. Consumers want it, and it’s here to stay—the sooner that we as an industry recognize those facts, the better.
