On December 7th, 374 Labs received ISO 17025 accreditation, becoming the first in Nevada to do so. The laboratory, based in Sparks, Nevada, is state-certified and now the only ISO 17025 accredited lab in the state, according to a press release. The laboratory is a member in both the Association of Commercial Cannabis Laboratories (ACCL) and the Nevada Cannabis Laboratory Association (NVCLA).

“As Nevada transitions into an adult-use cannabis market, it’s very important that the state’s cannabis testing laboratories are held to the highest standards – and ISO 17025 is a requirement of top testing laboratories in all industries from biotech to forensics in most major countries,” says Dr. Jeff Angermann, assistant professor in the University of Nevada, Reno’s School of Community Health Sciences.

According to the release, 374 Labs was a driving force behind Nevada’s round robin cannabis lab testing program. That program, administered by the Nevada Division of Public and Behavioral Health (DPBH) and the Nevada Department of Agriculture (NDA), sends cannabis samples to each state-certified cannabis lab for a full analysis, measuring the consistency in test results across labs. “In other states proficiency involves testing pre-prepared, purified samples and neglects the challenges of coaxing out delicate analytes from the complex array of compounds found in actual marijuana,” says Laboratory Director Jason Strull. “I commend the DPBH and NDA for facilitating such an advanced quality program.”
Also notable is the announcing of their partnership with Clean Green Certified, a third-party certification (based on USDA organic certification) for sustainable, organically based cannabis cultivation. “Nevada allows certain levels of pesticides like Myclobutanil on its certified marijuana, so we wanted a way for patients and consumers to able to distinguish marijuana that is grown using organic methods,” said Laboratory Director Jason Strull. According to Michael Seibert, managing member of 374 Labs, they have already started performing inspections for the third-party certification and the first facility inspected was Silver State Trading in Sparks, Nevada (certified for both production and cultivation).
Update: The No on Question 1 Campaign has rescinded their recount effort, according to the Portland Press Herald. “We promised folks that if we came to a point where we could not see any chance of reversing the result, we would not drag the process out,” says Newell Augur, legal counsel for No on 1 campaign. “We are satisfied that the count and the result are accurate.”
On Election Day in Maine, voters were heavily divided on Question 1, a ballot initiative that would legalize recreational cannabis. Voters passed the initiative, but with a very narrow margin, according to a WGME article.

Out of almost 760,000 ballots, Question 1 passed by a margin of only 4,073 votes, roughly 50.2% in favor and 49.8% against. Maine Secretary of State Matt Dunlap says State Police is responsible for collecting the physical ballots and bringing them to Augusta. Dunlap’s office is coordinating with volunteers to recount each vote by hand.
Dunlap is quoted saying there would have to be significant vote changes in every town to indicate any discrepancies in the polling. He says the state can recount up to 25,000 votes a day, but with the upcoming holidays, the recount will continue into 2017.
According to International Business Times, Gov. Paul LePage, who is a cannabis legalization opponent, has said he would delay the process of legalization even if the measure passed. He also said he would speak with president-elect Donald Trump regarding the enforcement of federal cannabis prohibition. Governor Lepage said if the Trump administration embraces states with legal cannabis then he too would honor the voters’ wish to legalize recreational cannabis.
Election Day 2016 resulted in historic gains for state level cannabis prohibition reform. Voters in California, Maine, Massachusetts and Nevada chose to legalize adult use of Cannabis sp. and its extracts while even traditionally conservative states like Arkansas, Florida, Montana and North Dakota enacted policy allowing for medical use. More than half of the United States now allows for some form of legal cannabis use, highlighting the rapidly growing need for high quality analytical testing.
For the uninitiated, analytical instrumentation can be a confusing mix of abbreviations and hyphenation that provides little obvious information about an instrument’s capability, advantages and disadvantages. In this series of articles, my colleagues and I at Restek will break down and explain in practical terms what instruments are appropriate for a particular analysis and what to consider when choosing an instrumental technique.
Potency Analysis
Potency analysis refers to the quantitation of the major cannabinoids present in Cannabis sp. These compounds are known to provide the physiological effects of cannabis and their levels can vary dramatically based on cultivation practices, product storage conditions and extraction practices.
The primary technique is high performance liquid chromatography (HPLC) coupled to ultraviolet absorbance (UV) detection. Gas chromatography (GC) coupled to a flame ionization detector (FID) or mass spectrometry (MS) can provide potency information but suffers from issues that preclude its use for comprehensive analysis.
Pesticide Residue Analysis
Pesticide residue analysis is, by a wide margin, the most technically challenging testing that we will discuss here. Trace levels of pesticides incurred during cultivation can be transferred to the consumer both on dried plant material and in extracts prepared from the contaminated material. These compounds can be acutely toxic and are generally regulated at part per billion parts-per-billion levels (PPB).
Depending on the desired target pesticides and detection limits, HPLC and/or GC coupled with tandem mass spectrometry (MS/MS) or high resolution accurate mass spectrometry (HRAM) is strongly recommended. Tandem and HRAM mass spectrometry instrumentation is expensive, but in this case it is crucial and will save untold frustration during method development.
Residual Solvents Analysis
When extracts are produced from plant material using organic solvents such as butane, alcohols or supercritical carbon dioxide there is a potential for the solvent and any other contaminants present in it to become trapped in the extract. The goal of residual solvent analysis is to detect and quantify solvents that may remain in the finished extract.
Residual solvent analysis is best accomplished using GC coupled to a headspace sample introduction system (HS-GC) along with FID or MS detection. Solid phase microextraction (SPME) of the sample headspace with direct introduction to the GC is another option.
Terpene Profile Analysis
While terpene profiles are not a safety issue, they provide much of the smell and taste experience of cannabis and are postulated to synergize with the physiologically active components. Breeders of Cannabis sp. are often interested in producing strains with specific terpene profiles through selective breeding techniques.
Both GC and HPLC can be employed successfully for terpenes analysis. Mass spectrometry is suitable for detection as well as GC-FID and HPLC-UV.
Heavy Metals Analysis
Metals such as arsenic, lead, cadmium, chromium and mercury can be present in cannabis plant material due to uptake from the soil, fertilizers or hydroponic media by a growing plant. Rapidly growing plants like Cannabis sp. are particularly efficient at extracting and accumulating metals from their environment.
Several different types of instrumentation can be used for metals analysis, but the dominant technology is inductively coupled plasma mass spectrometry (ICP-MS). Other approaches can also be used including ICP coupled with optical emission spectroscopy (ICP-OES).

When a cannabis sample is submitted to a lab for testing there is a four-step process that occurs before it is tested in the instrumentation on site:
It is ground at a low temperature into a fine powder;
A solution is added to the ground powder;
An extraction is repeated 6 times to ensure all cannabinoids are transferred into a common solution to be used in testing instrumentation.
Once the cannabinoid solution is extracted from the plant matter, it is analyzed using High Pressure Liquid Chromatograph (HPLC). HPLC is the key piece of instrumentation in cannabis potency testing procedures.
While there are many ways to test cannabis potency, HPLC is the most widely accepted and recognized testing instrumentation. Other instrument techniques include gas chromatography (GC) and thin layer chromatography (TLC). HPLC is preferred over GC because it does not apply heat in the testing process and cannabinoids can then be measured in their naturally occurring forms. Using a GC, heat is applied as part of the testing process and cannabinoids such as THCA or CBDA can change form, depending on the level of heat applied. CBDA and THCA have been observed to change form at as low as 40-50C. GC uses anywhere between 150-200C for its processes, and if using a GC, a change of compound form can occur. Using HPLC free of any high-heat environments, acidic (CBDA & THCA) and neutral cannabinoids (CBD, THC, CBG, CBN and others) can be differentiated in a sample for quantification purposes.
Near Infrared
Near infrared (NIR) has been used with cannabis for rapid identification of active pharmaceutical ingredients by measuring how much light different substances reflect. Cannabis is typically composed of 5-30% cannabinoids (mainly THC and CBD) and 5-15% water. Cannabinoid content can vary by over 5% (e.g. 13-18%) on a single plant, and even more if grown indoors. Multiple NIR measurements can be cost effective for R&D purposes. NIR does not use solvents and has a speed advantage of at least 50 times over traditional methods.
The main downfall of NIR techniques is that they are generally less accurate than HPLC or GC for potency analyses. NIR can be programmed to detect different compounds. To obtain accuracy in its detection methods, samples must be tested by HPLC on ongoing basis. 100 samples or more will provide enough information to improve an NIR software’s accuracy if it is programmed by the manufacturer or user using chemometrics. Chemometrics sorts through the often complex and broad overlapping NIR absorption.
Bands from the chemical, physical, and structural properties of all species present in a sample that influences the measured spectra. Any variation however of a strain tested or water quantity observed can affect the received results. Consistency is the key to obtaining precision with NIR equipment programming. The downfall of the NIR technique is that it must constantly be compared to HPLC data to ensure accuracy.
At Eurofins Experchem , our company works with bothHPLC and NIR equipment simultaneously for different cannabis testing purposes. Running both equipment simultaneously means we are able to continually monitor the accuracy of our NIR equipment as compared to our HPLC. If a company is using NIR alone however, it can be more difficult to maintain the equipment’s accuracy without on-going monitoring.
What about Terpenes?
Terpenes are the primary aromatic constituents of cannabis resin and essential oils. Terpene compounds vary in type and concentration among different genetic lineages of cannabis and have been shown to modulate and modify the therapeutic and psychoactive effects of cannabinoids. Terpenes can be analyzed using different methods including separation by GC or HPLC and identification by Mass Spectrometry. The high-heat environment for GC analysis can again cause problems in accuracy and interpretation of results for terpenes; high-heat environments can degrade terpenes and make them difficult to find in accurate form. We find HPLC is the best instrument to test for terpenes and can now test for six of the key terpene profiles including a-Pinene, Caryophyllene, Limonene, Myrcene, B-Pinene and Terpineol.
Quality Systems
Quality systems between different labs are never one and the same. Some labs are testing cannabis under good manufacturing practices (GMP), others follow ISO accreditation and some labs have no accreditation at all.
From a quality systems’ perspective some labs have zero or only one quality system employee(s). In a GMP lab, to meet the requirements of Health Canada and the FDA, our operations are staffed in a 1:4 quality assurance to analyst ratio. GMP labs have stringent quality standards that set them apart from other labs testing cannabis. Quality standards we work with include, but are not limited to: monthly internal blind audits, extensive GMP training, yearly exams and ongoing tests demonstrating competencies.
Maintaining and adhering to strict quality standards necessary for a Drug Establishment License for pharmaceutical testing ensures accuracy of results in cannabis testing otherwise difficult to find in the testing marketplace.
Important things to know about testing
HPLC is the most recommended instrument used for product release in a regulated environment.
NIR is the best instrument to use for monitoring growth and curing processes for R&D purposes, only if validated with an HPLC on an ongoing basis.
Quality Systems between labs are different. Regardless of instrumentation used, if quality systems are not in place and maintained, integrity of results may be compromised.
GMPs comprise 25% of our labour costs to our quality department. Quality systems necessary for a GMP environment include internal audits, out of specification investigations, qualification and maintenance of instruments, systems controls and stringent data integrity standards.
President-elect Donald Trump nominated Sen. Jeff Sessions from Alabama for Attorney General and Rep. Tom Price from Georgia as the new Health Secretary. Those appointments still require Senate approval before they are officially members of the cabinet. Neither of the picks to head the Department of Justice (DoJ) and the Department of Health & Human Services (HHS) is friendly to cannabis.
What’s the bad news?
Both of those agencies are at the center of any federal regulation of cannabis, including access for research. As Attorney General, Jeff Sessions would essentially have the ability to block any rescheduling efforts, as outlined in the Controlled Substances Act.

Sessions has made inflammatory, racist remarks and showed his disdain for cannabis users on multiple occasions. He disgracefully said at a Senate hearing in April, “Good people don’t smoke marijuana.” When he was a federal prosecutor, Sessions was a prominent advocate for the War on Drugs, and perhaps even still is.
Rep. Tom Price (R-GA) Photo: Gage Skidmore, Flickr
Tom Price, a Republican Congressman from Georgia, has voted repeatedly against pro-cannabis legalization bills, including twice against the Veterans Equal Access Amendment as well as the Rohrabacher/Farr Amendment, which “prohibits the use of funds in the bill to supersede State law in those States that have legalized the use of medical marijuana.” NORML’s Georgia Scorecard gave Tom Price a D grade for his previously voting against pro-cannabis bills.
What’s the good news?
While Sen. Jeff Sessions is certainly no friend to legal cannabis, I believe he is not a serious danger to the cannabis industry. This op-ed on CNN does a terrific job at summing up Sessions’ potential threat to the cannabis industry, but also why it may not be cause for a total panic. The author mentions a laundry list of DoJ priorities over cannabis, but I think the larger issue at hand is states’ rights.
Republicans are historically passionate when it comes to keeping states’ rights sovereign. With cannabis’ big wins on Election Day, a majority of the country’s population now lives in states where cannabis is legal.
Aaron Smith, executive director of NCIA
There is too much momentum behind legal cannabis for a new administration to waste precious resources and time on trying to disrupt it. States are getting too much tax revenue from regulating cannabis to just let the DoJ interfere with their economies. “Voters in 28 states have chosen programs that shift cannabis from the criminal market to highly regulated, tax-paying businesses,” says Aaron Smith, executive director of the National Cannabis Industry Association (NCIA). “Senator Sessions has long advocated for state sovereignty, and we look forward to working with him to ensure that states’ rights and voter choices on cannabis are respected.” Smith’s words in the NCIA statement are pointed and clear: this is a states’ rights issue at heart and they must respect that.
By forcing the states’ rights issue to the front, it is possible to put legal cannabis in a bipartisan lens, thus eliminating the possibility of a few old drug war stalwarts disrupting the industry. While rescheduling efforts could be thwarted for the coming years, I have faith that the federal government will not interfere with states that legalize cannabis.
From the perspective of sustainable cannabis cultivation models, it seems clear that outside of the particular cultivation methodology adopted, that operational efficiency and the implementation of lean manufacturing principles will be necessary for successful and truly “sustainable” businesses, in the current, ever growing, cannabis space.
Implementing lean manufacturing principles as an integral part of the cannabis cultivation facility just makes sense- it is a manufacturing operation after all. From a lean perspective, doing away with the non-value-added costs in the supply chain and production model are quite important.
Let’s look at this case study as evidence for the necessity of operational efficiency:
A 300-light flowering, indoor cultivation facility in Colorado.
The system was purchased with ongoing pest/disease issues, recent updates to Colorado’s approved pesticide list, had prompted the implementation of an updated integrated pest management (IPM) program, which had been moderately successful in developing an albeit short-term solution to keeping ongoing root aphids, powdery mildew, and botrytis, to name a few, at bay.
This existing facility was producing roughly 60 pounds of trimmed cannabis per week, equivalent to almost $6M annual gross, however they were losing a percentage of their yields to product that did not pass Colorado’s contaminant testing requirements.
It is important to note that any deviation from the existing manufacturing schedule and system would create a change to the potential productivity of the system, for better or worse.
At the most basic level, one would hope that a new operator taking over an existing facility would analyze the system and implement incremental or perhaps major changes to create more efficient and profitable outcomes. That being said, currently the average grower likely doesn’t have much understanding of the lean manufacturing process. That will undoubtedly change.
When we look at basic manufacturing facility operations, on an annual gross potential basis, each daily task not completed on the existing manufacturing timeline is, at least, a 0.3% (1/365) loss in potential productivity. In monetary terms, for this particular facility, each 0.3% equates to a potential $18,000 in lost productivity.
The information that follows is taken from observations during the first week of this facility ownership transition and below is a generalized outline representing just one aspect of the operational inefficiencies (created or existing) that were observed :
Plant group A put into flowering 4 days behind schedule (4 days x 0.3%) =1.2%
Plant group B transplanted 3 days behind =0.9%
Plant group C transplanted 7 days behind =2.1%
Plant group D (clones) taken 7 days behind =2.1%
IPM applications not completed for 7+ days
That equals a 6.3% loss in potential annual productivity, which translates into a rough estimate of up to $378,000 in lost revenue.
Changes to the nutrient program in the midst of the plant’s life cycle had created nutrient deficient plants in all stages of vegetative and flowering growth, coupled with changes to the existing IPM program, all add to the potential losses incurred. Deviations in the plant nutrition program and IPM scheduling are hard to quantify mid-cycle, but will certainly be quantifiable when the hard numbers come home to roost.
These inefficiencies, once compounded, could potentially equal more than a 20% loss in potential productivity during the subsequent 3.5 month plant cycle. The current 60 pounds-per-week would likely be reduced for the next 2 months, down to roughly 50 pounds, or even much less, per-week. This could become a loss upwards of $500,000 in annual potential revenue in the first quarter of operation alone.
These seemingly small and incremental delays in the plant production cycle are all greatly compounded. The end result is that each subsequent cycle of plants is slightly smaller due to delays in transplanting and less days at maximized vegetative growth, etc. Undoubtedly, the cumulative effect of these operational inefficiencies creates a significant drop in the existing level of productivity, with the end result being a significant, undesired loss of revenue.
The sum of the lessons learned from this cultivation facility, is this: a sustainable operation, in the most pragmatic sense, is an efficient one both in terms of productivity and in terms of the carbon footprint and waste generated. The more streamlined and successful the operations are, the greater likelihood of success. Perhaps all of this is to say don’t forget about all the little parts that make up the whole, and strive to create a work environment/corporate culture that empowers your employees, your managers and all involved to participate and contribute to the process of improving the operations for mutual benefit.
Lessons learned from the aerospace manufacturing industry: Even the smallest zip tie on a spaceship matters! Some food for thought: If it’s truly beneficial it should stick around… If it is beneficial and it’s not sticking around, then there are limiting factors in the system that need to be addressed.
Legal marijuana sales are expected to hit $6.7 billion in 2016, with the market expected to climb to $21.8 billion in sales by 2020. As legal cannabis sales rise, cannabis labels are quickly becoming one of the fastest growing markets for label manufacturers.
An Industry Gaining Legitimacy
Since California first legalized medical cannabis in 1996, the cannabis industry has grown considerably. Voters in four states legalized recreational cannabis last week on Election Day, including California, which is currently the world’s 6th largest economy. Voters in another four states legalized medical cannabis as well, bringing the total to 28 states with some form of legalization measure.
An example of a cannabis flower label in Oregon with all of the required information.
What’s more, public support for full cannabis legalization is at an all-time high 61 percent, according to a recent survey from the AP-NORC Center for Public Affairs Research. The market is here to stay.
Cannabis flower labels
Legal cannabis has primarily consisted of dispensaries selling cannabis flower or leaves (ready-to-smoke marijuana) in pouches or childproof containers. Regulations have essentially required two cannabis labels for the pouches: a branded label on the front and a regulatory label on the back. Many dispensaries also use pre-printed pouches.
Similar to the way alcohol labels must contain information for alcohol content, the informational labels that sit on the backs of pouches are legally required to provide certain accurate information, including:
The universal symbol required on all cannabis products in Colorado
THC %
CBD %
Net weight in grams
Lab name and test number confirmation
Batch number
Date tested
Strain name
Warning Label
And cannabis flower labels are just the beginning. Many smoke-free product categories are emerging with similar labeling requirements. These often allow for increased branding opportunities that will afford better profit margins for label suppliers. Some of the many products in this young category include:
Edibles — such as dark chocolates, baked goods, snack crackers and teas infused with cannabis.
Topicals — such as pain-relieving lotions and creams.
Tinctures — cannabis-infused oils that are applied in drops to the tongue.
Bottom line: For label and packaging suppliers, cannabis represents one of the fastest growing market opportunities today and the opportunities extend way beyond labeling for the flower itself.
Managing Compliance
As more and more states move toward legalization and regulation, uneven laws in different states are increasingly governing the market. Businesses must respond to ever-changing requirements, including labeling standards. While many dispensaries have gotten away with minimalist labels, states are increasingly demanding dispensaries meet more stringent legal requirements. For example, Oregon passed new labeling requirements this year and products that failed to meet them by October 1, 2016 were not allowed on store shelves.
Label suppliers entering the market must keep abreast of the changing regulations and be able to help brands navigate them. They need to work to understand the intricacies of this new market, rather than simply looking to redirect the capabilities they already possess. See the original post here.
Dr. Zacariah Hildenbrand, chief scientific officer and partner at C4 Laboratories, is currently researching some of the lesser-known molecules in cannabis, and he’s on to something. His research focuses on discovering new molecules, determining their therapeutic effects and expanding our understanding of the constituents of cannabis.
Dr. Zacariah Hildenbrand, chief scientific officer and partner at C4 Laboratories.
Dr. Hildenbrand received his Ph.D. from the University of Texas at El Paso where he researched the molecular architecture involved in hormone-dependent cancers. At the University of Texas Southwestern Medical Center in Dallas, his post-doctoral research contributed to the development of a novel therapy for the treatment of chronic myeloid leukemia, a blood-borne cancer that afflicts small children. He has published over 25 peer-reviewed scientific journal articles and hopes to do the same with his research in cannabis.
After a career of scientific consulting, Dr. Hildenbrand met Ryan Treacy, founder and chief executive officer of C4 Laboratories, in 2015 when Treacy launched the company. In June of 2015, the laboratory began operations, providing Dr. Hildenbrand the opportunity to embark on a new and exciting field of research- cannabis.
Ryan Treacy, founder and chief executive officer at C4 Laboratories.
They currently collaborate with Dr. Kevin Schug of the Shimadzu Center for Advanced Analytical Chemistry (SCAAC) at the University of Texas, Arlington and together Drs. Schug and Hildenbrand are pursuing a DEA license to expand their current cannabis research. The SCAAC is a $10.0+ million analytical laboratory with instrumentation that only a handful of people in the world has access to.
C4 Laboratories, based in Mesa, Arizona, currently offers a range of services for cannabis analysis including terpene and cannabinoid analytics, microbial, pesticide, fungicide and insecticide testing. In addition to the standard gamut of tests, they also specialize in cultivation analytics like mold and mildew culture testing, viral detection with sentinel plants and comprehensive analysis of environmental conditions.
What makes their company unique is their multidisciplinary effort to characterize the therapeutic compounds found in cannabis, the C4 Cannabinomics Collaborative. We sit down with Dr. Zac Hildenbrand to talk cannabis science, his research and what they hope to accomplish with the C4 Cannabinomics Collaborative.
CannabisIndustryJournal: What is the C4 Cannabinomics Collaborative?
Dr. Zacariah Hildenbrand: The C4 Cannabinomics Collaborative is an open collaboration between growers and scientists to discover new molecules in cannabis and to have a better characterization of individual cannabis strains based on the active constituents found in each sample. We are facilitating the collaboration of some of the world’s best cannabis growers with world-class scientists to find new information about the plant.
What we want to accomplish in this work is identifying novel molecules. Because of the [federal government’s] restrictions in researching cannabis, there is very little peer-reviewed literature on many of the compounds found in cannabis. We want to secondarily find out what those molecules do in the human body and thus make recommendations for strains targeting specific conditions.
We also want to understand the strains currently out there by determining the most established cannabinoids and terpenes via chemotyping. You hear a lot of people talking about the effects of an Indica or Sativa and making recommendations based on that. We want to find chemical signatures based on cannabinoids and terpenes and make recommendations based on that. There are a lot of problems at hand when discussing strain names scientifically. There are nomenclature issues- people calling the same strain different names, people giving multiple names to the same strain to make it appear that their strain portfolios are more diverse.
We can identify the chemical signatures in strains based on the major cannabinoids and terpenes. Based on the terpenes and chemical profile we can determine more accurate recommendations for patients as well as in recreational applications. All of this, again, discovering the new molecules, identifying the current strains, is so we can make more informed decisions regarding cannabis use. It is not a panacea but it is a very robust plant. There are a lot of terpenes with anti-inflammatory responses. Other molecules help with blood flow, sleep, regulating blood glucose, and we all know the cases of CBD helping children with convulsions and epilepsy. We want people to make sure they have the most up-to-date information.
CIJ: How is your collaboration with the SCAAC at UT Arlington contributing to this work?
Dr. Hildenbrand: One of the instruments we use there is a supercritical-fluid-extraction supercritical-fluid-chromatography mass-spectrometer (SFE-SFC-MS). With that instrument, we can do the extraction on the machine with an extreme level of sensitivity. It is ideal for drug discovery and identifying molecules in the parts-per-quadrillion range. This particular instrument allows us to detect molecules with an extreme level of sensitivity without volatizing them during the sample extraction process.
The Shimadzu Center for Advanced Analytical Chemistry
We want to acquire samples of unique cannabis from growers that will work with us to discover new cannabis constituents. We are in the process of getting a DEA license so that we can send products across state lines to the center at UT Arlington to perform the advanced characterization. They have instrumentation that only a handful of people in the world have access to, which gives us the best opportunity to explore the unknown. When we discover new molecules, find out what they do on the molecular level, we can then isolate these compounds and ultimately use this newfound knowledge for the development of effective nutraceuticals.
CIJ: What molecules are you researching right now?
Dr. Hildenbrand: Some of the low-hanging fruit in our research looks at identifying compounds similar to the better-studied compounds such as THC and CBD. THCV has a very similar structure to THC, but has a shorter acyl carbon chain (3 carbons vs. 5).
Tetrahydrocannabivarin (THCV)
THCV doesn’t induce a psychoactive response (like THC), but it does improve fat utilization, so it has remarkable potential for medicine. We are looking at what conditions are required for it to occur naturally. Cannabis doesn’t produce THCV in a high amount. 0.7% by weight is the most we have seen in Arizona. In Oregon, where craft cannabis has been refined to a much higher degree, we have heard rumblings of some strains containing up to 3% THCV. We want to find out if this is a possible weight loss tool. Our research in CBDV is very much the same.
CBL is the breakdown product of CBC when it is treated with ultraviolet light. We know absolutely nothing about what CBL does. If we find a strain that produces high amounts of CBC, we can then treat it with UV light and force the conversion to CBL, and then ultimately determine what it does. This is a good example of low-hanging fruit and the versatility of cannabis. Based on the biogenesis of the cannabinoids, we can alter the profile of cannabis products using a series of biochemical reactions.
Cannabicyclol (CBL)
For example, we have been helping clients in Arizona look for a quality sleep aid in cannabis. Certainly, Indica strains will help, but the molecule CBN helps specifically with sleep abnormalities. As CBN is formed as a byproduct when CBD or THC are oxidized, we see some producers using liquid nitrogen to oxidize CBD, leading to higher CBN levels. I would like to think we are in the age of understanding CBD, THC and the major terpenes,but there are a whole milieu of compounds that require our attention and THCV, CBDV and CBL are just a few that we want to devote our efforts to right away.
CIJ: What are your plans in the immediate future?
Dr. Hildenbrand: We are in the process of finalizing the documents to bring a C4 laboratory into Oregon where we can do quite a bit of research and where we’ll have access to some very unique cannabis. We will offer full compliance testing per ORELAP and OLCC regulations, but we also want to acquire samples (free of charge) from growers that want to collaborate with us to discover new molecules. We’ve been lucky enough to start working with growers like Adam Jacques and Chris West in Eugene, but we also want to be available to other growers who want to contribute to this research.
CIJ: What are your long-term goals with this project?
Dr. Hildenbrand: At a basic level, we hope to expand the current understanding of the cannabis plant. There is a lot of “bro science” and anecdotal claims out there. There is so much that we don’t know about cannabis that we cannot simply rely on anecdotal claims for each strain. We want to bring cannabis into the same light as any pharmaceutical-grade or biomedical research.
We need to be characterizing this plant with the same level of detail as other pertinent molecular therapies. In doing so there are a lot of potential discoveries to be made and we might be able to unlock the future of medicine. A drug like Marinol, for example, has been met with mixed reviews because its only one dimensional. Furthermore, we find that the terpene molecules are tremendously beneficial and this interplay between cannabinoids and terpenes is something that we want to explore further. All and all we wish to further illustrate the therapeutic capacities of cannabis within the contexts of specific ailments and medical conditions, while discovering the medicine of the future.
Update: With 100% reporting (589 of 589 precincts), voters in Maine passed Question 1, legalizing recreational cannabis by a very narrow margin of 50.2% to 49.8% (378,288 in favor and 375,668 against is a margin of only 2,620 votes)
Voters in California, Massachusetts, Maine and Nevada passed ballot initiatives legalizing the recreational use of cannabis, creating huge new markets for the cannabis industry overnight. Voters in North Dakota, Florida, Montana and Arkansas passed ballot initiatives to legalize forms of medical cannabis. Voters by a margin of 52.2% to 47.8% rejected Arizona’s Proposition 205, which would have legalized recreational cannabis.
With 100% of the votes in for Maine’s Question 1, voters narrowly passed legalizing recreational cannabis, the polls show it won by a very slim margin, less than 3,000 votes.
New Frontier Data and Arcview Market Research released an Election Day update to their growth projections for the cannabis industry by 2020. The release projects: “The legalization of cannabis in California, Massachusetts, Nevada, Florida, Arkansas and North Dakota will result in new markets that account for $7.1 billion in sales by 2020. We project the overall U.S. cannabis market will exceed $20.9 billion by 2020.” Those numbers include overall cannabis sales and assume the markets are all fully operational by 2018.

According to Giadha DeCarcer, founder and chief executive officer of New Frontier, there is overwhelming support for medical cannabis and a majority of Americans are in favor of legalizing recreational cannabis as well. “The ten initiatives on the ballot reflect the accelerating public debate on legal cannabis access,” says DeCarcer. “The passage of California’s adult use measure and Florida’s medical initiative expand legal access into two of the country’s most populous states.” The market potential is notably enormous in California, it currently being the 6th largest economy in the world. “Additionally, the passage of the measure in Massachusetts opens the first adult use market in the Northeast extending the reach of legal adult use access from coast to coast,” says DeCarcer. “The passage of the measures in Arkansas and North Dakota shows that public support on this issue is not solely confined to urban, liberal markets but extends into conservative rural states as well.”
According to the release, by 2020 California could reach a total market size of $7.6B and Massachusetts could grow to $1.1B. Massachusetts being the first mover in the Northeast to legalize recreational cannabis will be watched very closely by a number of surrounding states that appeared bullish on cannabis legalization previously.

Leslie Bocskor, president and founder of Electrum Partners, believes the Election Day results will bring an influx of investing opportunities to the industry. “We are going to see a diverse approach from the irrationally exuberant to the sophisticated and experienced investor and entrepreneur getting involved, creating businesses and investing in the industry that will create innovation, jobs, wealth and tax revenue far beyond the consensus expectations,” says Bocksor. “The cannabis industry is more than one industry; it is an entire ecosystem, impacting so many verticals, such as agriculture, industrial chemicals from hemp, pharmaceuticals, nutraceuticals and more. We see the funding of innovation that might have been absent without the velocity and heft that has come from this phenomenon,” adds Bocksor. As these newly legalized markets begin to launch, it will require a considerable amount of time to see the industry flesh out in each new state.

Donald Trump winning the presidential election and the GOP retaining control over the House and Senate could mean a lot of uncertainties for the future of the cannabis industry on a national scale. President-elect Trump has previously flip-flopped on the issue of cannabis legalization, but has said in the past he favors leaving the issue of medical use up to the states, advocating for access to medical cannabis, while recently saying he opposes regulating cannabis for adult use, according to the Marijuana Policy Project. The MPP gave him a C+ grade for his views toward cannabis.
On The O’Reilly Factor in February 2016, Trump told the conservative political commentator that he supports medical cannabis while opposing the recreational use. “I’m in favor of it [access to medical cannabis] a hundred percent. But what you are talking about [recreational use], perhaps not. It’s causing a lot of problems out there [in Colorado],” says Trump. It is still unclear at this time exactly what Trump’s policy will be for the now 28 states that have some form of legal cannabis.
Aaron Smith, executive director of NCIA
Aaron Smith, executive director of the National Cannabis Industry Association (NCIA), appeared optimistic regarding the outcomes of Election Day. “More than 16 million voters, including in two of the three most populated states in the nation, chose legal, regulated cannabis programs that promote safety, boost the economy, help sick patients and address social injustices,” says Smith. In the press release, the NCIA spelled out their priorities for congressional action on cannabis policy: Opening up bank access for state-compliant cannabis businesses, ending the effects of federal tax code Section 280E on cannabis businesses and removing cannabis from the Controlled Substances Act via descheduling. “Last night’s results send a simple message – the tipping point has come,” says Smith.
Three health alerts were issued Thursday, November 4th for contaminated cannabis sold to consumers at North Bend, Salem and Eugene dispensaries. Green-Way Medicinal in Salem and Stonies in North Bend sold two strains of cannabis flower found to have high levels of piperonyl butoxide, an ingredient commonly found in pesticides that acts as a synergist to amplify the effects of certain compounds.
The two batches in question, including the strains Pleeze (batch number G6J0039-02) and Dryzl (batch number G6J0039-01), were found to contain the potentially dangerous chemical at levels of 15.39 ppm and 16.24 ppm, respectively. The Oregon Health Authority (OHA) action level for piperonyl butoxide is 2.0 ppm. To see the full health alert, click here.
The dispensary in Eugene, Flowr of Lyfe, sold one strain of cannabis that had levels of the insecticide spinosad over the 0.2-ppm action level. The very popular indica hybrid, Dutch Treat (batch number G6J0018-01), was found to contain 0.9-ppm of spinosad. Though it still tested above the 0.2-ppm action level for that insecticide, it pales in comparison to October’s health alert, where a batch of cannabis had over 200 times the acceptable level of that insecticide. Both spinosad and piperonyl butoxide are considered toxic to humans.
According to the health alert, “All tests were performed by an OHA-accredited and Oregon Liquor Control Commission-licensed laboratory.” It is unclear exactly how or why the cannabis was able to get transported and transferred from the grower to the dispensary and then sold to consumers after failing the pesticide test. According to Jonathan Modie, spokesman for the OHA, they are currently investigating the matter and following up with the dispensaries and growers to find out what happened. “We need to find out how this got transferred in the first place and then sold,” says Modie. “They had access to the test results and should have been able to determine for themselves that these products should not have been sold or transferred.”
“We don’t know, we are still gathering information, there is a risk of civil penalty as well as losing your registration for a dispensary or grower that illegally transferred products that have tested for analytes above the action levels,” says Modie, when asked if punitive measures would be taken. While there are no particular regulations for this scenario in performing a mandatory recall, the OHA is obligated under law to issue health alerts when there is a situation that might affect public health, according to Modie.
“We deal with this with infectious disease outbreaks or during a food borne illness outbreak; if they [the public] can avoid it by hearing from us then we want to get the word out and this is a very similar situation.” For medical patients that purchase potentially contaminated cannabis such as this, it is easy to contact them to have the patient dispose or return the cannabis. Dispensaries are not required to collect information from recreational customers, and most dispensaries do not, which is a major problem when this situation happens, as it has twice in the past two weeks.
“We can never do too much communication,” says Modie. “We will let the public know in any way possible that they should return this product or dispose of it responsibly.”
