Anyone with a search engine can piece together how much THC certain strains produce and what their characteristics are. Oh wait- there’s an app for that… or dozens, I lose count these days.
Nefarious lab results are rampant in our communityLet’s take one of my favorites, Dutch Treat; relaxing, piney and sweet with a standard production of 18-25% THC, according to three different reviews online. So, did I raise an eyebrow when I saw Dutch Treat on Oregon shelves labeled at 30% THC? Did I take it in to an independent, accredited lab and have it tested for accuracy? You bet your inflated potency results I did! The results? Disappointing.
Nefarious lab results are rampant in our community; it is hurting every participant in our industry affected by the trade, commerce and consumption of recreational cannabis.
“I have had labs ask me what I want my potency numbers to look like and make an offer,” says David Todd, owner and operations manager of Glasco Farms, a craft cannabis producer in central Oregon. “It’s insane- I want to stand behind my product and show through scientific fact that I produce a superior flower.”
But without enforcement of lab practice standards, producers are being pressured to play dirty. In her third year cultivating at a two-tier recreational cannabis farm, a producer who wished to remain anonymous sent me an email about the pressures she is up against to produce high THC strains:
“The only sure way to get my product on the shelf at a profitable price is with THC 25% or above. Not a lot of strains have that potential, but the market has plenty with 28% to 32% floating around so I have to go with the same labs as the rest of the independent farmers to get the best numbers I can. The lab I use … return(s) good numbers.”
Those “good numbers,” aka high THC %, are the driving force of sales. A strain tests at 20% THC and it sells for $1,000/lb. Then it tests at 25% THC, and sells for $1300/lb. You produce cannabis for sale- this is your business. And labs are telling you that they can manipulate samples and reports to make you more money. Everyone else is doing it. If you don’t, your product isn’t “good enough” to sell. What do you do?Labs should operate ethically.
It’s a vicious cycle perpetuated by lies, lack of enforcement resources, coercion and undereducation. We are all responsible. Yet, ask who the source of the problem is and everyone points fingers across the circle.
The consumers are uneducated about cannabis and only focus on THC. The dispensaries and budtenders should be educating them. Producers should take a stand and use an honest lab. Labs should operate ethically.
I repeat: Oregon, we have a problem.
It’s time to stop living in a land where Dutch Treat is hitting 30% THC. It’s time for everyone to demand auditing and ethics.
Laws have been set forth on how to sample, prep, test and report analyses for cannabis to ensure fair commerce, consumer health and public safety. But there’s a clear need to blind test the different labs, and for unbiased, third-party research and development.
As federal eyes turn to the Oregon to investigate black market activity, regulatory bodies are tightening their grip on licensees to maintain legal validity and avoid shut down.
The time to demand change and integrity is now.The crack-down began on August 23, 2018, when the OLCC investigated several prominent producers’ practices. Black market distribution incurred the harshest penalty; the OLCC revoked their wholesale license due to multiple violations.
“We want good compliant, law-abiding partners as OLCC marijuana licensees,” says Paul Rosenbaum, OLCC Commission Chair. “We know the cannabis industry is watching what we’re doing, and believe me, we’ve taken notice. We’re going to find a way to strengthen our action against rule breakers, using what we already have on the books, and if need be working with the legislature to tighten things up further.”
Trends in METRC data lay the foundation for truth, and it’s time to put it to use. “The Cannabis Tracking System worked as it should enabling us to uncover this suspicious activity,” says Steven Marks, OLCC Executive Director. “When we detect possible illegal activity, we need to take immediate steps …”
Potency fraud might not be at the top of the list for investigation, but labs and producers are breaking the law, and there will be consequences. ORELAP and OLCC have the right to investigate and revoke licenses of labs that are falsifying data and consumers can file claims with the Department of Justice.
At this year’s Food Safety Consortium a couple weeks ago, the newly launched Cannabis Quality Track featured a number of panels and presentations that highlighted the many intersections between food safety and cannabis. One particular topic of interest was measuring the quality and safety of cannabis products through laboratory testing. At the event this year, representatives from the leading laboratory accreditation bodies in the country sat together on a panel titled Accreditation, Regulation & Certification: Cannabis Labs and Production.
The new ISO 17025:2017 standard was a topic addressed pretty early in the panel. Tracy Szerszen introduced the topic with a recap of the 2005 standard. “With 17025, for those that are familiar with the older version, 2005, there are really two sections of the standard for that one,” says Szerszen. “The newer standard is a little bit different, but there is a quality management system review that we do and we look at the laboratory to ensure that they are testing appropriately based on what they applied for. So, for cannabis labs, they typically have the same scope in types of methods with respect to microbiology and chemistry, and we are making sure they are following the standard from a technical standpoint, meaning they have the right equipment, the appropriate personnel and also have a quality management system.”
Chris Gunning followed that up with a closer look at the changes coming to the new 2017 standard. “If you are familiar with the 2005 version, you know that a lot of the clauses started out with a ‘you shall have a policy and procedure for doing X,’” says Gunning. “One of the major changes to the 2017 version is it gives laboratories more latitude on whether they need to have a policy/procedure to do certain things.” Gunning says the 2017 version is much more of an outcome-based standard. “As far as assessing to it, it becomes a little harder from our side because we can’t say you have to have this quality manual or you have to have this procedure that were going to assess you to. We are more open to looking at the outcomes.”
Christopher Gunning, life sciences accreditation manager with A2LA
The most interesting change to the ISO standard comes with addressing the idea of risk. “One of the newest concepts in this standard is risk and how you assess your risk to your organization how you assess risk of impartiality, how you assess your measurement uncertainty when you are creating decision rules,” says Gunning. “Those are the big concepts that have changed in the 2017 standard in that it is more outcome-based and introducing the concept of risk more.”
After discussing some of the broader changes coming to the 2017 version, the panelists began delving into some common pitfalls and issues labs face when trying to get accredited. “From our experience, in Michigan, the new standard was written into the regulations, but a lot of labs were already accredited to 2005,” says Szerszen. “So, we actually contacted the state and explained to them that they have three years to transition. And some states will say ‘too bad, we want the 2017 ISO,’ so some of the cannabis labs are asking us to quickly come back so they can get appropriate licensing in the state and do a transition audit quickly.” She says most states seem to be comfortable with the current transition period everyone has, but it certainly requires some discussion and explanation to get on the same page with state regulators. “November 29, 2020 is the deadline for moving to the new 2017 standard.”
In addition to state requirements like traceability and security on top of an ISO 17025 accreditation, labs can run into issues not typically encountered in other testing markets, as Gunning mentioned during the panel. “One of the hardest parts of getting accredited is the need for properly validated methods, for all the different matrices in samples,” says Gunning. “Some of the biggest hurdles for new labs getting assessed are validation and the availability of reference materials and proficiency testing samples that meet their state requirements.” Those are just a handful of hurdles that labs aren’t usually anticipating when getting accredited.
Natalia Larrimer, engagement and program development manager, ANAB
Another big topic that generated a lot of dialogue during the panel was the need for a national accreditation standard for cannabis testing labs, one that Natalia Larrimer is advocating for. “Many laboratories are operating facilities in more than one state and what they are facing is a different set of criteria for laboratory recognition in each state, says Larrimer. “One initiative that we would love to see more support for, is a set of uniform requirements nationally. ACIL is currently working on developing these type of requirements which would be in addition to the ISO/IEC 17025 standard and specific for cannabis industry…” Larrimer says she’d like to see these requirements recognized nationally to get labs on the same page across multiple states. “This includes requirements for things like security, traceability, proficiency testing, sampling and personnel competence. The industry would greatly benefit from a uniform cannabis testing program across the US, so that testing facilities in Oregon are operating to the same criteria as facilities in California or Colorado, etc.”
The panelists went into greater detail on issues facing the cannabis lab testing industry, but also delved into certifications for food safety and quality, an important new development as the infused products market grows tremendously. Stay tuned for more highlights from this panel and other talks from the Food Safety Consortium. We will be following up this article with another that’ll shed some light on food safety certifications. Stay tuned for more!
Compliance should be top of mind for California’s cannabis operators. As the state works to implement regulations in the rapidly-growing cannabis industry, business owners need to be aware of what’s required to stay in good standing. As of January 1, 2019, that means reporting data to the state’s new track-and-trace system, Metrc.
What Is Track-and-Trace?
Track-and-Trace programs enable government oversight of commercial cannabis throughout its lifecycle—from “seed-to-sale.” Regulators can track a product’s journey from grower to processor to distributor to consumer, through data points captured at each step of the supply chain. Track-and-trace systems are practical for a number of reasons:
Taxation: ensure businesses pay their share of owed taxes
Quality assurance & safety: ensure cannabis products are safe to consume, coordinate product recalls
Account for cannabis grown vs. cannabis sold: curb inventory disappearing to the black market
Helps government get a macro view of the cannabis industry
The California Cannabis Track-and-Trace system (CCTT) gives state officials the ability to supervise and regulate the burgeoning cannabis industry in the golden state.
What Is Metrc?
Metrc is the platform California cannabis operators must use to record, track and maintain detailed information about their product for reporting. Metrc compiles this data and pushes it to the state.
Who Is Required To Use Metrc?
Starting January 1, 2019, all California state cannabis licensees are required to use Metrc. This includes licenses for cannabis: Proper tagging ensures that regulators can quickly trace inventory back to a particular plant or place of origin.
Cultivation
Manufacturing
Retail
Distribution
Testing labs
Microbusinesses
How Does Metrc Work?
Metrc uses a system of tagging and unique ID numbers to categorize and track cannabis from seed to sale. Tagged inventory in Metrc is sorted into 2 categories: plants and packages. Plants are further categorized as either immature or flowering. All plants are required to enter Metrc through immature plant lots of up to 100/plants per lot. Each lot is assigned a lot unique ID (UID), and each plant in the lot gets a unique Identifier plant tag. Immature plants are labeled with the lot UID, while flowering plants get a plant tag. Metrc generates these ID numbers and they cannot be reused. In addition to the UID, tags include a facility name, facility license number, application identifier (medical or recreational), and order dates for the tag. Proper tagging ensures that regulators can quickly trace inventory back to a particular plant or place of origin.
Packages are formed from immature plants, harvest batches, or other packages. Package tags are important for tracking inventory through processing, as the product changes form and changes hands. Each package receives a UID package tag, and as packages are refined and/or combined, they receive a new ID number, which holds all the other ID numbers in it and tells that package’s unique story.
Do I Have To Enter Data Into Metrc Manually?
You certainly can enter data into Metrc manually, but you probably won’t want to, and thankfully, you don’t have to. Metrc’s API allows for seamless communication between the system and many of your company’s existing tracking and reporting tools used for inventory, production, POS, invoices, orders, etc. These integrations automate the data entry process in many areas.As California operators work to get their ducks in a row, some ambiguity and confusion around Metrc’s roll out remains.
Adopting and implementing cannabis ERP software is another way operators can automate compliance. These platforms combine software for point of sale, cultivation, distribution, processing and ecommerce into one unified system, which tracks everything and pushes it automatically to Metrc via the API. Since they’ve been developed specifically for the cannabis industry, they’re designed with cannabis supply chain and regulatory demands in mind.
As California operators work to get their ducks in a row, some ambiguity and confusion around Metrc’s roll out remains. Only businesses with full annual licenses are required to comply, leaving some temporary licensees unsure of how to proceed. Others are simply reluctant to transition from an off-the-grid, off-the-cuff model to digitally tracking and reporting everything down to the gram. But the stakes of non-compliance are high— the prospect of fines or loss of business is causing fear and concern for many. Integrated cannabis ERP software can simplify operations and offer continual, automated compliance, which should give operators peace of mind.
Last week, on November 20, dispensaries in Massachusetts began selling cannabis to recreational consumers. The market was off to an obviously electric start, following the path of other states that legalized recreational cannabis. Consumers waited in long lines on opening day, more than two years after voters in the state legalized cannabis.
While this marks an important milestone as the first legal recreational cannabis sales began on the East Coast, regulators only approved two licensed dispensaries to begin operations on opening day. Those two retailers allowed to begin sales are Cultivate Holdings in Leicester and New England Treatment Access in Northampton.
The Cannabis Control Commission (CCC), the state’s regulatory body overseeing the new marketplace, received some criticism for taking more than a year to establish and implement regulations for the industry. In April of this year, regulators were just preparing the final rules.
It has taken them a fair amount of time to establish the regulatory framework, but much of the recent delays were due to a lack of laboratory licenses. Earlier in November, the CCC finally approved two laboratories for testing in the recreational market. Those two labs are MCR Labs LLC of Framingham and CDX Analytics LLC of Salem. With the labs approved for third-party independent testing in the recreational market, regulators began allowing retailers to open shortly after.
Shawn Collins, executive director for the CCC, told Boston 25 News that they are delivering on the voters’ requests to provide for a safe marketplace. “When Massachusetts voters legalized adult-use cannabis, they communicated a desire to purchase products that are safely regulated and properly tested,” says Collins. “The Commission has done scrupulous due diligence to make that vision a reality and ensure licensed independent testing labs maximize public health and public safety.”
It is official. British doctors as of November 1, 2018, can now write prescriptions for medical cannabis. But what does that really mean? And is this truly a victory or merely an opening in the fierce resistance to and outright battle against cannabinoids as medicine?
A Real Victory Or Another Stall?
Many in the advocacy community in Europe are profoundly split. On one hand, yes, the British decision, like other sovereign medical cannabis reforms in Europe over the last two years, is a victory. The British government, like many before it, has thrown in the towel on denying basic access to medical cannabis. But what does this mean, especially in a country which may well be facing shortages of basic food products and other kinds of medications in under half a year if things continue to blow up on Brexit and there is no “people’s vote” to save the day?
Cultivated product would, normally, be slated to come from Portugal and Spain where Tilray and Canopy in particular have set up cultivation centers. If things continue to head to a negotiated Brexit, it is inevitable that imported cannabis would fall into the same category of everything else set to come into England by boat or lorry. It is highly unlikely that the NHS would authorize full payment for cannabis flown in from Canada. Especially with British Sugar’s existing cannabis plantations in Norfolk as well as the budding cultivation deals now finally flowering all over the country if not in Ireland.There are many who expect that medical cannabis will actually save public healthcare systems a great deal of money.
Brexit Is The Bigger Worry, So What About Cannabis?
It may also seem to some that access to cannabis is the least of the country’s worries. Actually this is a discussion deeply embedded in the politics and drama in London and Brussels right now. It is also at the heart of Brexit itself. Namely the propaganda associated with European divorce that ran along the lines of “saving the NHS.”
In fact, the legalization of medical use in the UK, just as it is in countries across Europe (Germany being the best and most current ongoing example) will do much to shine a light on how creaky and outdated the medical provision system really is here. Especially when it comes to approving new drugs for large numbers of people quickly. This was, ultimately the goal of public healthcare. See penicillin, not to mention most inoculation drugs or vaccines for childhood diseases (like Polio).
One of the great ironies of cannabis legalization in Europe of course is that it is also often shining a light on how far this concept, not to mention funds for proper delivery, has been allowed to lapse. There are many who expect that medical cannabis will actually save public healthcare systems a great deal of money. That is if it can finally make its way into widespread medical distribution.
And cannabis is a drug like no other. Why? Despite all the pharmacization of the plant that is going on right now as producers are being forced to produce pills and oils for the medical market, cannabinoid treatments will not be pushed so easily into “orphan” status – since whole plant products can treat a range of diseases. This is important in terms of supply and negotiated prices down the road. But in the short term, cannabis is falling into a couple of strange categories created by organized public healthcare, insurance mandates (both public and private), the demands being placed on producers in this space to act more like pharmaceutical companies, limited public spending budgets, and a changing demographic where chronic conditions treated by cannabis are a whole new ballgame. Namely patients are living longer, and not necessarily old.
So while it is all very well and good for British doctors to begin to write prescriptions for cannabis, merely having one does little good for most patients. In fact, this usually means the battle is only half won.
Why?
National Healthcare Is Still Functional In Europe
As foreign as it is to most Americans, most European countries operate more or less the same way when it comes to healthcare. First of all, all of the national systems in operation in Europe today, including the UK, were set up in the aftermath of WWII to recover from devastation most Americans, especially today, never experienced personally.
These healthcare systems were set up to first and foremost be inclusive. In other words, the default is that you are covered. 90% of populations across Europe in fact, including the UK, are covered by their national healthcare systems. “Private” health insurance actually only covers about 10% of the population and in some countries, like Germany, is mandatory once annual income rises above a certain level.
However this system is also based on a very old fashioned notion of not only medical care, but treatment of chronic conditions. Namely, that most people (the mostly well) face low prices for most drugs. Further, the people first in line to get “experimental” or “last use” drugs (as cannabis is currently categorized in Europe no matter its rescheduling in the UK), are patients in hospitals. With the exception of terminal patients, of course, that is no longer the case.
Patients in the UK can expect to face the same kinds of access problems in the UK as in Germany.That is why, for example, so many disabled people began to sue the German government last year. They could not afford treatment until their insurer approved it. Monthly supplies in legal pharmacies are running around $3,000 per month for flower. Or about 8 times the total cash budget such people have to live on (in total) on a monthly basis.
In fact, because of this huge cost, approvals for drugs like cannabis do not actually happen at the front line of the insurance approving process, but are rather kicked back to regional (often state) approvals boards. As a result, approval for the right to take the drug with some or all of the cost covered by insurance, is actually limited to a much smaller pool of people right now – namely the terminally ill in hospital care. In Germany, the only people who are automatically approved for medical cannabis once a doctor writes the prescription, are the terminally ill. For everyone else it is a crapshoot. Between 35-40% of all applications in Germany are being turned down a year and a half into medical legalization. Some patients are being told they will have to wait until next year or even 2020.
And once that prescription is actually approved? Patients in the UK can expect to face the same kinds of access problems in the UK as in Germany. Namely pharmacies do not readily stock the drug in any form.
In the meantime, patients are turning back to the black market. While the online pharmacy discussion is different in the UK than Germany, which might in fact make a huge difference for the right approvals system, most patients in the UK still face a long fight for easy and affordable access covered by public healthcare.

Chris Martinez, co-founder and chief operating officer of EVIO Labs Florida
Fast-forward almost a year and EVIO Labs Florida is continuing their expansion in the state, now with locations in Broward County and Gainesville. “We are always looking at opportunities to better serve our clients and the patients of Florida,” says Martinez. “Opening Gainesville within a year of Davie was a goal we set for our team. We knew there was a need and opening Gainesville helped support the continued growth of FL medical marijuana program.” He says that between the two locations, they can now process upwards of 1,400 samples a day.
According to Martinez, much of that expanded throughput is thanks to their partnership with Shimadzu. “Our relationship with Shimadzu is very unique,” says Martinez. “Shimadzu instrumentation allows us to test in parts per billion for accuracy and sensitivity levels that empower us to see deep into the chemical makeup of these medicines. Operating in this space where speed and turnaround times are key, these instruments provide us with a platform to meet 24/48-hour deadlines.” They can now screen for contaminants such as pesticides, heavy metals, residual solvents, mycotoxins, aflatoxins and pathogens using instruments such as HPLC, GC-MS/MS, LC-MS/MS and ICP-MS, all provided by Shimadzu.
While Florida doesn’t currently have a final rule on testing thresholds, there are proposed regulations that would require independent lab testing for medical cannabis products. “Our clients are self-regulating at this time and in favor of the current proposed regulation,” says Martinez. “The proposed regulations will give Florida the most comprehensive and stringent testing regulation in the U.S. and arguably the world.”
For Martinez and the rest of the EVIO Labs Florida team, this is about protecting public health. “Our lab’s main focus is always first and foremost patient safety,” says Martinez. “As the market continues to grow, we continue to innovate through business intelligence software and other technologies to streamline the testing process for our customer’s.”
Bearing through four voluntarily recalls in the first two months since the transition window ended, the California cannabis industry showed its commitment to providing safe goods for its consumers. Recalls are considered the removal of products deemed unsafe at the point of retail. With unsafe product already on shelves, it is that much more important to have a thought out strategy if a recall need arises. Currently, the California Department of Public Health-Manufactured Cannabis Safety Branch is the only regulatory agency in the state of California with recall stipulations for California cannabis companies. Thus, the onus is on individual cannabis companies to initiate their own recall plans.
Why establish a recall plan if one is not compulsory? To start, a cannabis product recall is more challenging than recalls in other industries because of the classification as a Schedule 1 drug and the misunderstanding and stigma of the drug that promotes fake news. These considerations affect the way both the government officials and consumers perceive cannabis recalls – not preparing ahead of time could be devastating to your brand. Furthermore, a recall is not just a one day headache – in December 2017, the Inspector General of Department of Health and Human Services found that food companies took 57 days on average to initiate a recall after the Food and Drug Administration (FDA) first learned a product was potentially hazardous. Not only is a recall tricky to navigate and time intensive, a recall can also be costly – a joint study by the Food Marketing Institute (FMI) and the Grocery Manufacturers’ Association (GMA) in the USA found that 77% of the study respondents estimated the financial impact to be up to $30 million dollars; 23% reported even higher costs. One major factor of the financial impact to consider is that many retailers do not remove only the affected products, instead sweeping entire lines and brands. To estimate how much a food recall would cost your company, researchers Moises Resende-Filho and Brian Burr developed a model to estimate the direct costs of a food recall. To take a step back, it is true that, while recalls can be tricky to navigate, time intensive and costly, recalls are generally infrequent. At the same time, you never know where or when a recall could happen. For example, your manufacturing process might be flawless, but a supplier may suddenly issue a recall or the retail facility is compromised. Moreover, not all recalls are equal – imagine that consumers would react differently to an undeclared allergen on the label versus a life threatening pathogen in a product distributed to patients with weakened immune systems. Ergo, it is strategic for every cannabis company (grower, manufacturer, retail, etc.) to have a recall plan to be ready for any type of recall situation.
Take these 6 tips in designing a recall plan:
Product recalls due to manufacturing errors in sanitation cause mistrust among consumers.
Before a Recall
1) Be familiar with how recalls work by staying up to date with recalls
2) Write a recall plan. Select a recall template and fill in your company information, but also take into consideration any regulations on recalls at the federal, state, and county levels.
3) Record everything that was said and done. If there was no prewritten recall plan, during a recall is a good time as any to begin documenting all actions and communication – internal within the management team and external with business partners (suppliers, retailers) and external with the consumers.
4) Find the flaw in the product. Why is the product being recalled? This is important to know, whether it was your item or not, to better answer the next question of “What happens with the recalled product?” The most common causes for a recall in the USA are identified in the joint study mentioned above by the FMI and GMA.
After a Recall
5) Reevaluate the recall plan. Compare to a reputable third-party auditing standard (example here is Safe Quality Food Institute’s SQF Food Safety Code for Manufacturing Edition 8). Updates to the recall plan are inevitable and constant. The changes may be due to updates in company products, adjustments in the recall network or the experience gained when going through a recall. Also keep an eye out for updates to templates of recall plans. Conduct mock recalls with different recall origins.
6) Reevaluate the food safety plan. After finding the flaw in the product, identify the flaw in the process and improve. Examples to improve the food safety plan may be to: amend the supplier approval program, refine process flow, polish the sanitation program or revise the preventative maintenance program. The foundation of a recall plan is having a robust food safety plan to minimize the risk of running a recall.
Genome sequencing has made remarkable strides since the initiation of “The Human Genome Project” in 1990. Still, there are many challenges that must be overcome before this methodology can reach its fullest potential and be useful in serving as a method of Cannabis sativa genetics verification and tracking throughout the cannabis supply chain. Several major milestones that must be realized include end-to-end haploid type (single, unpaired set of chromosomes instead of complete paired set or “diploid”), long read, resolved genome sequences at a reasonable cost within a reasonable timeframe and with confidence in accuracy (Mostovoy et al.). These genomes are typically generated as shorter reads that are then scaffolded (Fig 1.) or matched to reference genomes in order to build a longer continuous read. While shorter sequencing reads indeed lower the cost barrier for producing more genomic data, it has created another issue as a result of this short-read technology.
Figure 1: Four sets of sequencing data (long-read WGS, Hi-C, optical mapping, and short-read WGS) were produced to generate the goat reference genome. A tiered scaffolding approach using optical mapping data followed by Hi-C proximity-guided assembly produced the highest-quality genome assembly. (Bickhart et al.)
There are two main issues with the more affordable short read sequencing methodology, the first being that sequential variants are typically not detected, especially if they involve a ton of repeats/inverted repeats, due to the limitation of the current referenced Cannabis genomes and the mapping process of the short-read sequences. This is especially unfortunate because larger variants can have up to a 13% variance within a diploid multichromosomal genome, such as Cannabis sativa, and this variance is thought to largely contribute to disease in various species, or maybe terpene profile in Cannabis sativa. Not being able to detect these variances with more affordable sequencing methodologies is particularly problematic and reference genomes produced with short read sequences are typically highly fragmented. The second limitation is the inherent errors, gaps and other ambiguities associated with taking tons of short read sequences and combining them all, like a jigsaw puzzle, in order to draft the larger genomic picture. While there is software with algorithms to assist in deciphering raw sequences, there is still much more work to be done on this challenge, considering that cannabis genome sequencing is new genomics territory. Unfortunately, as researchers seek higher and higher levels of data quality, shortcomings of this type of sequencing technology begin to become apparent. This sort of sequencing methodology relies heavily on reference sequences. This isn’t much of an issue with microbial genomes, which tend to be rather short and typically have one chromosome, however, when seeking to analyze much longer genomes with multiple diploid chromosomes and tons of mono and dinucleotide repeats, problems arise (English et al.).
Figure 2: Blockchain Digital Stamping Certificate which publicly documents the date and time of the completion of this work. (Mckernan – Crypto Funded Public Genomics)
The other category of sequencing is long read sequencing. Long read sequencing is as it sounds, the deciphering of much longer DNA strands. Of course, the technology is limited by the quality of the DNA captured, therefore, special high molecular weight DNA extraction protocols must be deployed in order to obtain the proper DNA quality (Fig. 3). Once this initial limitation is overcome there is the stark cost of long read sequencing technology. PacBio without a doubt makes one of the highest quality long read sequence generating instruments that has ever graced the field of biotechnology, but due to the steep price tag of the machine, progress in this field has been stifled simply because it just isn’t affordable and the read depth for mammalian and plant genomes is currently almost completely prohibitive until read lengths double in length for this instrumentation. In order to produce what is considered to be a “validated genome” both short read and long read sequencing methodologies are combined. Long read sequencing data is used to produce the reference contigs because they are much easier to assemble, then short read sequencing is scaffolded against the reference contigs as a sort of “consensus validation” of the long read contigs.
Figure 3: Depiction of various DNA high molecular weight DNA quality captured during cannabis genome submission project. (Mckernan – Crypto Funded Public Genomics)
Despite the shortcoming of utilizing short read sequencing technology for analysis of the cannabis genome, it is still useful especially when combined with other longer read sequencing technologies or optical mapping technologies. Kevin McKernan, chief scientific officer of Medicinal Genomics, has been working feverishly to bridge the information gap between the cannabis genome and other widely studied plant genomes. As a scientist that worked on the Human Genome Project in 2001, McKernan has a demonstrated history of brilliance in the field of genomics. This paved the way for him to coordinate the first crypto funded and blockchain notarized sequencing project (DASH DAO funded) (Fig. 2), which was completed in 60 days, and surprisingly showed that the cannabis genome is over 1 billion bases long which is 30% larger than any cannabis genome submitted prior to his work. By reaching the standard of 500kb N50 set forth by the Human Genome Project, Kevin McKernan was able to see new aspects of the cannabis genome that were not visible due to the fragmented genomic data previously generated. Information such as a possible linkage of THCA synthase and CBDA synthase genes is crucial when seeking to use the cannabis genome for verification and tracking purposes. This is because special linkages can be considered a type of “genetic marker” that may be used to differentiate cannabis cultivars and lineages. There are many types of genetic markers, including SNP (single nucleotide polymorphisms), VNTR (variable number tandem repeats) and even patterns of gene expression. Funding and recording of cannabis genomics must be further developed in order for potential markers to be identified and validated via larger scale genome-wide association studies.
These technologies, when combined, often reduce the number of scaffolds while increasing the percent of resolved genome by filling in gaps within the drafted genome. Nanopore sequencing is an especially interesting and innovative sequencing technology that is useful in many ways. One of the most powerful uses of this technology is its ability to upgrade the quality of draft and pushed genomes by resolving poorly organized genomes and genomic structure for a fraction of the time and cost of other long read sequencing platforms (Jian et al.), making it an excellent candidate for solving cost and time constraints. Nanopore’s portability and convenience makes it a real-time solution to solving genetics-based problems and questions. A notable use of this technology is recorded during an epidemiological outbreak in Africa, its proof of concept in pathogen detection in space, and its ability to detect base modifications during sequencing process. Even still there are more uses to this exciting technology and it has the potential to elevate cannabis genomics and the field of genomics entirely, while remaining portable and expeditious. A shortcoming of the Nanopore sequencing platform is its low sequencing coverage, which makes this platform inefficient for applications like haplotype phasing and single nucleotide variant detection due to the number of variants to be detected being smaller than the published variant-detection error rates of algorithms using MinION data. Single nucleotide variants can be considered to be genetic markers, especially markers for disease, so this is what inhibits Nanopore from resolving our cannabis genome sequencing problems, as of today.
There are genetic markers to discover, molecular biology protocols to optimize, and industry wide potential for exciting collaborationMany algorithmic problems seem to occur due to input data quality. Typical input data quality suffers as the reads get longer and the sequencing depth gets shorter, resulting in not enough data being generated by the sequencing to provide confidence in the genome assembly. To mitigate this, scientists may decide to fractionate a genome, sequence it, or they may clone a difficult to sequence region with highly repetitive regions in order to produce reads with greater depth and thus resolve the region. They can then perform single molecule sequencing to resolve genome structure then determine and confirm the place of the cloned region. Thus, it seems that the best solution to the limitation of algorithms is to be aware of sequencing platform limitations and compensate for these limitations by using more than one sequencing platform to obtain enough pertinent data to confidently produce authentic, “validated” genome assemblies (Huddleston et al.). With input data being critical in producing accurate sequencing data, standardization of DNA isolation protocols, extraction reagents and any enzymes utilized may be deemed necessary.
To conclude, the field of cannabis genomics is teeming with opportunities. There are genetic markers to discover, molecular biology protocols to optimize, and industry wide potential for exciting collaboration. More states will need to take into account the lack of federal government research grant availability and begin to think of creative ways to get cannabis science funds to continue the development of this industry. Specifically speaking, developing a feasible method for genetic tracking of cannabis plants will require improvements within the availability of sequencing technology, improvements in deploying the resources to these projects in order for them to be completed expeditiously, and standardization/validation of methods and SOPs used in order to increase confidence in the accuracy of the data generated.
A special thank you to all of my cannabis industry mentors that have molded and elevated my understanding of current needs and applied technologies within the cannabis industry, without you there would be no career within this industry for me. You are immensely appreciated.

According to a press release published yesterday, Steep Hill Hawaii announced the opening of their second location on the Big Island. Their first location located on Oahu and operating for a little over a year, was the first cannabis-testing laboratory to be certified by the State of Hawaii Department of Health (HDOH). It’s also the first ISO/IEC 17025:2005 accredited cannabis testing lab in the state.
Owner and CEO of Steep Hill Hawaii, Dana Ciccone announced the second location yesterday. “”We are thrilled to open up our new location in Kailua Kona, Hawaii,” says Ciccone. “We have been working closely with the Department of Health and we look forward to working together with the large patient population and the two new dispensaries opening very soon.” Ciccone says with the new location they are focusing on quick turnaround times, good service and competitive prices.
According to Dr. Andrew Rosenstein, CEO of Steep Hill, they want to help provide safe medicine and quality testing to the Hawaii medical cannabis community. “In extending its services, Steep Hill Hawaii is committed to providing safe medicine and high quality testing to Hawaii’s patient community,” says Rosenstien. “Dana and the Steep Hill Hawaii team have worked hard to open up this new location and will continue to support cultivators and dispensaries in this emerging market.”
The Food Safety Consortium, taking place November 13-15 in Schaumburg, Illinois, will host a series of talks geared towards the cannabis industry this year. The newly launched Cannabis Quality Track features a number of panels and presentations designed to highlight the many intersections between food safety and cannabis.
Jenna Rice, Director of Operations at Gron Artisan Chocolates
The track will have presentations discussing food safety planning in cannabis manufacturing, HACCP, GMPs, regulatory compliance and supply chain issues among other areas.
Ben Gelt, board chair of the Cannabis Certification Council, is moderating a panel titled What’s In My Weed? that will delve into issues like supply chain, production and other difficulties in creating cannabis products and the challenges inherent in teaching consumers to be more discerning.

Kimberly Stuck, Founder of Allay Compliance Consulting
Ben Gelt and the Cannabis Certification Council orchestrated the development of this panel to help promote their #WhatsInMyWeed consumer awareness and education campaign. “The Cannabis Certification Council believes consumer education campaigns like #Whatsinmyweed are critical to drive standards and transparency like we see in food,” says Gelt. “What better place to discuss the food safety challenges the cannabis industry faces than the Food Safety Consortium”
Before Kim Stuck founded Allay Compliance Consulting, she was the first Marijuana Specialist for a public health authority in the nation, where she was working with regulators in Denver, Colorado. She is currently a cannabis food safety expert and a Certified Professional of Food Safety (CP-FS) through NEHA. She has helped Colorado and California develop cannabis food safety requirements. “I will discuss pitfalls we have experienced in the regulation of cannabis in Denver and what mistakes not to make,” says Stuck. “I’d also like to talk about how to be prepared for when those regulators start to come in to facilities.”
Kristen Hill, MIP Director at Native Roots Dispensary
Kristen Hill is the MIP Director at Native Roots, arguably one of the largest dispensary chains in the world. She oversees 30 employees in Native Roots’ MIP facility where product testing and quality assurance of products are all led under her guidance. Her background includes managing quality assurance and regulatory compliance with FDA regulations, among other areas. She said she’s particularly excited to talk about implementing manufacturing best practices in the cannabis space. “Cannabis is maturing and is beginning to shape operations around long standing best practices in other industries,” says Hill.
Leslie Siu, Founder and CEO of Mother & Clone
Leslie Siu brings to the panel 17 years of liquor, tobacco and pharma marketing and operational oversight plus global digital and experiential campaigns. Her company, Mother & Clone, produces infused, sublingual cannabis sprays. Based in Colorado, Mother & Clone’s team of biochemists are Merck alumni, currently working towards GMP standards in preparation for Canada, slated to be on shelf in the spring of 2019. Her main consideration for cannabis product development comes from what she has learned from the FDA in traditional industries- what they will and will not tolerate.

And cannabis is a drug like no other. Why? Despite all the pharmacization of the plant that is going on right now as producers are being forced to produce pills and oils for the medical market, cannabinoid treatments will not be pushed so easily into “orphan” status – since whole plant products can treat a range of diseases. This is important in terms of supply and negotiated prices down the road. But in the short term, cannabis is falling into a couple of strange categories created by organized public healthcare, insurance mandates (both public and private), the demands being placed on producers in this space to act more like pharmaceutical companies, limited public spending budgets, and a changing demographic where chronic conditions treated by cannabis are a whole new ballgame. Namely patients are living longer, and not necessarily old.
