ASTM International Launches Cannabis Committee

By Aaron G. Biros

According to a press release published March 1^st, ASTM International formed a committee focusing on “creating technical standards and guidance materials for cannabis and its products and processes.” ASTM, founded in 1898, as the American Section of the International Association for Testing Materials, predates other standards organizations such as IEC (1906), ANSI (1918) and ISO (1947). ASTM International is a non-profit organization devoted to the development of international standards. For more than a century, ASTM has served as a leading venue for consumers, industry and regulators to work collaboratively under a balanced and consensus–based process to craft voluntary consensus standards.

ASTM International meets the World Trade Organization (WTO) principles for developing international standards, and maintains the attributes outlined in the National Technology Transfer and Advancement Act (NTTAA) for a voluntary consensus standards development organization. ASTM International is known throughout a variety of industries for creating voluntary consensus standards for products, systems, services and materials. ASTM standards are used globally in research and development, product testing, quality systems, commercial transactions, and more.

On January 18^th, 2017, the American Public Health Association hosted thirteen industry stakeholders representing state laboratories, standards developers, research institution, academia, cultivation centers, auditors and software compliance providers, according to Lezli Engelking, founder of the Foundation of Cannabis Unified Standards (FOCUS), who is involved and familiar with the process. The planning meeting discussions included a summary of where the request was initiated, why a standards activity was necessary and the results of ASTM’s exploratory efforts. At the conclusion of the planning meeting, it was decided by vote, that ASTM should move forward with the activity.

On February 28^th, 2017, roughly 60 stakeholders and cannabis industry representatives met at ASTM International’s headquarters in Conshohocken, Pennsylvania. The volunteer committee on cannabis, designated D37 by ASTM, is a result of inquiries flooding the company regarding cannabis since 2015, states the press release.

The committee will focus on six technical areas, forming subcommittees:

Indoor and outdoor horticulture and agriculture,
Quality management systems,
Laboratory,
Processing and handling,
Security and transportation, and
Personnel training, assessment, and credentialing.

Dr. Ralph Paroli, immediate past chairman of the board and director of R&D in measurement science and standards at the National Research Council of Canada, was voted to serve as the committee’s first chairman. “With its decades of experience in industries such as pharmaceuticals, medical devices, packaging, agriculture, pesticides, and more, ASTM International is the perfect place for standards development for the cannabis industry,” says Paroli.

Pending ASTM International board of directors’ approval (anticipated late April 2017), a shift of standards development efforts has been made from FOCUS to the ASTM International technical committee D37 on cannabis and its products and processes.

“FOCUS could not be more pleased by ASTM’s decision to further the development of internationally harmonized cannabis standards,” says Engelking. “This is desperately needed, and an enormous step in the right direction of legitimizing the cannabis industry. We are thrilled FOCUS standards will be included, and honored to be a part of this exciting process.” During this transition period, interested stakeholders can get directly involved through the FOCUS website and then follow directions provided by FOCUS.

According to Engelking, third-party, cannabis-specific certifications for cultivation, retail, extraction, infused products and laboratories are provided by FOCUS for cannabis businesses committed to providing safe, consistent and quality products. FOCUS certification helps businesses decrease liability and risks, maximize efficiency, reduce costs and differentiate their brands.

“FOCUS encourage all stakeholders to participate in this important process,” says Engelking. “ASTM has an incredible standards development system in place that allows for many different levels of participation.” During 2017, ASTM is offering free temporary memberships. After 2017, stakeholders will need to join as a participating member.

AG Sessions Ties Legal Cannabis to Violence, States React

By Aaron G. Biros

No Comments

At the Department of Justice on Monday, Attorney General Jeff Sessions told reporters he believes cannabis use is unhealthy and leads to more violence, according to Politico. “I don’t think America is going to be a better place when people of all ages, and particularly young people, are smoking pot,” Sessions told reporters. “I believe it’s an unhealthy practice and current levels of THC in marijuana are very high compared to what they were a few years ago.” Those comments come a week after press secretary Sean Spicer suggested that the opioid crisis is tied to recreational cannabis use and seemed to hint that President Trump is okay with legal medical cannabis, but that the administration might not approve of recreational cannabis.

During a press conference last week, White House press secretary Sean Spicer told reporters “I do believe you will see greater enforcement of it,” referring to the enforcement of the Controlled Substances Act on recreational cannabis. He went on to make the distinction between medical and recreational use clear, while deferring to the Department of Justice, saying they will be looking further into the matter.

Much like press secretary Spicer incorrectly tied legal cannabis to the opioid crisis, Attorney General Sessions incorrectly tied legal cannabis to an increase in violence. “We’re seeing real violence around that,” says Sessions. “Experts are telling me there’s more violence around marijuana than one would think and there’s big money involved.” He did not discuss who those experts were or how he came to that conclusion. There are a number of studies refuting his claims, suggesting no causal link between legal cannabis and violence, with one study even suggesting a reduction in violent crimes after legalizing cannabis.

Sessions has not mentioned any specific policy actions that he would take on the enforcement of federal law. “We’re going to look at it. … And try to adopt responsible policies,” says Sessions. Jeff Sessions making these comments should come as no surprise as he expressed his disdain for cannabis a number of times and has been known to be a Drug War stalwart. President Trump promised during his campaign that he supports medical cannabis and the matter should be left up to the states. These recent comments by his newly appointed press secretary and attorney general suggest the administration may not honor that campaign promise.

Politicians in states that have legalized cannabis were quick to condemn the comments and uphold this as an issue of states’ rights. Colorado Governor John Hickenlooper told reporters legal cannabis is in their state’s constitution and he intends to uphold the will of the voters. Oregon State Rep. Knute Buehler (R-Bend) said in a press release, “I hope the new President and Attorney General keep their hands off Oregon’s marijuana law.” Regulators in Nevada have also said they plan to move forward with implementing legal recreational cannabis regulations, despite any federal actions or comments. Bob Ferguson, Washington State attorney general told the Associated Press, “We will resist any efforts to thwart the will of the voters in Washington,” and has requested a meeting with Sessions to discuss his policies. California Lt. Governor Gavin Newsom wrote a letter to President Trump telling him not to follow through on those threats of greater enforcement. “The government must not strip the legal and publicly supported industry of its business and hand it back to drug cartels and criminals,” Newsom wrote to Trump. “Dealers don’t card kids. I urge you and your administration to work in partnership with California and the other eight states that have legalized recreational marijuana for adult use in a way that will let us enforce our state laws that protect the public and our children, while targeting the bad actors.”

At this time, it remains unclear exactly how the Trump administration will address federal cannabis policy, but these vague and ominous statements from top federal officials continue to raise eyebrows in the cannabis industry. Until President Trump comes out with a clear stance on legal cannabis, those in the cannabis industry fear a federal crackdown on legal recreational cannabis is looming.

WH Press Sec. Sean Spicer Hints at Trump Admin. Stance on Cannabis

By Aaron G. Biros

2 Comments

During a press conference on Thursday, February 23^rd, White House press secretary Sean Spicer made a number of comments hinting at the Trump administration’s stance on legal cannabis. He identified a clear distinction that he makes between medical and recreational cannabis laws, while mentioning President Trump’s previous statements on medical cannabis. Roby Brock, a journalist at Arkansas news website Talk Business & Politics, asked a question about the state and federal conflict in cannabis laws. “The Obama administration chose not to strictly enforce those federal marijuana laws,” says Brock. “My question to you is with Jeff Sessions over at the Department of Justice as AG, what is going to be the Trump administration’s position on marijuana legalization where it is in a state-federal conflict like this?”

Sean Spicer replied with more of the same of his previous statements regarding the Trump administration’s stance on cannabis legalization. “There are two distinct issues here: medical marijuana and recreational marijuana,” says Spicer. “I think medical marijuana- I’ve said before that the president understands the pain and suffering that many people go through, who are facing especially terminal diseases and the comfort that some of these drugs, including medical marijuana, can bring to them. And that’s one that congress, through a rider in 2011, I think put in the appropriations bill saying the Department of Justice wouldn’t be funded to go after them.” The rider in the appropriations bill he is referring to is the Rohrabacher–Farr amendment that became law in December of 2014, but must be renewed each fiscal year. That piece of legislation provides for exactly what he said- preventing the Justice Department from using funds for activity that might interfere with state’s legal medical cannabis programs. Regarding the actual conflict between federal and state laws, Spicer said “I do believe you will see greater enforcement of it,” referring to the Department of Justice enforcing the Controlled Substances Act.

Spicer went on to make some questionably ill-informed remarks, including linking recreational cannabis use to the opioid crisis. “There is a big difference between that [medical marijuana] and recreational marijuana,” says Spicer. “And I think that when you see something like the opioid addiction crisis blossoming in so many states around this country, the last thing we should be doing is encouraging people- there is still a federal law that we need to abide by… When it comes to recreational marijuana and other drugs of that nature.” Though those comments are unclear, it could suggest that Mr. Spicer believes in a possible link between recreational cannabis use and the opioid crisis, or at least grouping them in the same category. While there is not much evidence suggesting of the link he is referring to, a study published in 2014 in JAMA Internal Medicine, a peer-reviewed medical journal published by the American Medical Association, suggests a possible link between medical cannabis laws and the decrease in opioid overdoses.

Spicer continued to emphasize his distinction between medical and recreational use of cannabis. “I think there is a big difference between medical marijuana, which states where it is allowed, in accordance with the appropriations rider, have set forth a process to administer and regulate that usage versus recreational marijuana, and that is a very very different subject,” says Spicer. National Cannabis Industry Association executive director Aaron Smith issued a statement regarding Spicer’s comments.

“It would be a mistake for the Department of Justice to overthrow the will of the voters and state governments who have created carefully regulated adult-use marijuana programs,” says Smith. “It would represent a rejection of the values of economic growth, limited government, and respect for federalism that Republicans claim to embrace.” Smith says he was very disappointed when he heard press secretary Spicer relate cannabis to opioid addiction. “Science has discredited the idea that marijuana serves as any kind of gateway drug, and the addiction and death rates associated with opioids simply do not occur in any way with cannabis,” says Smith. In October 2016, NCIA published a report identifying cannabis as a possible solution to the opioid crisis.

Isaac Dietrich, chief executive officer of MassRoots, a social networking platform for medical cannabis, sees Spicer’s words having a direct impact on his business. “I have a feeling our stock is going to take a beating tomorrow, but that just creates an opportunity for investors who believe in the long-term trajectory of the cannabis market,” says Dietrich. He goes on to directly refute Spicer’s statements. “Colorado is one of the only states in the nation that is seeing a decline in opioid deaths — that’s not a coincidence,” says Dietrich. “Cannabis is a healthy alternative to pain pills and heroin, not a gateway to it.”

Press secretary Sean Spicer did not allow a reporter present at the press conference to ask a follow up question on the matter.

Implementing Real Science in Cultivation and Extraction

By Aaron G. Biros

No Comments

Formed in 2015, Outco is a vertically integrated, licensed producer of medical cannabis in Southern California. Outco manages Outliers Collective, the first licensed dispensary continually operating in San Diego County. They operate the first licensed cultivation on Native American land in Southern California, the first cultivation building permit in Southern California and the first licensed extraction facility in San Diego County. Outco is on track to be the largest licensed producer of medical cannabis in Southern California.

Lincoln Fish, co-founder and chief executive officer of Outco

The company prides themselves on attention to detail; the well versed team implements real science in their cultivation and extraction processes. Lincoln Fish, co-founder and chief executive officer of Outco, has more than 30 years of experience as an entrepreneur. Before entering the cannabis industry, Linc started and sold companies in the healthcare technology and nutraceutical spaces.

With construction underway at new facilities, Outco is anticipating an expanding market and higher demand.

Fish’s experience with FDA regulations in nutraceuticals prepared him for running a business in such a tumultuous, highly regulated environment like cannabis. “One thing I took from the nutraceutical industry is how to present products to consumers and letting them know it is safe, effective and consistent,” says Fish. He says he noticed a serious lack of consistency in products. They tested 25 different vape cartridges, with their own oil, to find a consistent product they can use and know that consumers will safely and consistently get the same results. “There is a lot of room for more professionals and a lot of room for more science,” says Fish. “We try to position ourselves in a way that is consistent with where we think policy will go so we are very careful with recommendations from a scientific standpoint, patient information and product safety.”

Starting at a seed or cutting, plants are grown with the protection of biological control agents

According to Fish, they currently distribute cannabis products to about 75 licensed dispensaries in Orange County, San Diego and Los Angeles. With construction underway at their cultivation facility on Native American land, Fish says they plan to generate roughly 2600 pounds of cannabis each month. Gearing up for that in addition to the expanding recreational market requires some planning in advance, says Fish. Part of that plan is making sure quality controls are in place to keep consistency in the product quality and dosage. They are also actively seeking to open their distribution channels further.

“We are building out a full lab of our own in addition to third party testing to perform internal quality controls,” says Fish. Equipped with their own laboratory instrumentation like HPLC and GC, they hope to establish proper in-house quality controls as well as provide that resource to younger startup companies. As one of the founding partners of Canopy San Diego, an ancillary startup accelerator, Fish sees great potential in working with younger companies to get them off the ground. Fish met Outco’s vice president of extraction, Dr. Markus Roggen, at a Canopy San Diego event. It was there that they had the idea to build a startup accelerator for companies that actually touch the plant- extractors, cultivators and infused-product manufacturers, as opposed to a startup accelerator that would only help ancillary businesses.

Dr. Markus Roggen, vice president of extraction

Dr. Roggen, who is an organic chemist by training, heads up Outco’s supercritical CO2 extraction operation. “I came to the ‘art’ of cannabis extraction with an open, yet scientifically focused mind,” says Dr. Roggen. “My approach was to look past the myths and stories about extraction methods and focus on finding data, as there really wasn’t much available. I therefore, from the beginning, started to study the capabilities of our extraction equipment by chemometric methods.” Chemometrics is the science of relating measurements made on a chemical system or process to the state of the system via applications of mathematical methods. “Already the first sets of experiments showed that long-held beliefs in the cannabis community were inaccurate,” says Dr. Roggen. “For example the particle size of extracted material matters. Or that it is possible to preserve and even isolate terpenes by CO2 extraction methods.” With plans to have a full plant and analytical chemistry laboratory on site, they hope to perform more research that focuses on optimizing extraction processes.

Plant irrigation and fertigation procedures are determined via experimentation

Dr. Allison Justice leads their cultivation team with a background in greenhouse management and commercial horticulture. Dr. Justice says plants are grown, starting at a young age (seed or vegetative cutting), with the protection of biological control agents. “Biological control is a management strategy that entails the release of beneficial insects or fungi, such as parasitoids and predators, in order to suppress or regulate insect populations in greenhouses and grow rooms,” says Dr. Justice.

Dr. Allison Justice, vice president of cultivation

When implemented properly, this eliminates the need to use synthetic pesticides. “Biological control agents are not put in place to eradicate pest populations yet are applied as preventives to minimize plant damage and maintain their own populations.” They are constantly evaluating light types, spectrum and intensity to determine optimal ranges, according to Dr. Justice. They don’t use any pre-mixed “cannabis” nutrient supplements for their plants, instead they design an experiment to determine the desired levels and ratios of essential plant nutrients. “We have found it crucial to determine what ratios of nutrients the plant actually needs and by knowing this, we know how to manipulate the recipe determined by the plant’s given nutritional symptoms,” says Dr. Justice. Every type of adjustment in cultivation and extraction is based on results from experimentation rooted in legitimate science. Instead of guessing when it might be time to harvest, they use a water activity meter, logging and recording all the data to determine the appropriate time to trim and cure plants. Performing analytical testing at every step is key, says Fish.

Looking toward the recreational market, Fish sees an obvious opportunity to expand their wholesale operations substantially, with several larger new cultivation projects planned. “The key though is to produce flower and concentrate offerings with the same standards we employ for medical cannabis,” says Fish.

QuEChERS 101

By Danielle Mackowsky

No Comments

Sample preparation experts and analytical chemists are quick to suggest QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) to cannabis laboratories that are analyzing both flower and edible material for pesticides, mycotoxins and cannabinoid content. Besides having a quirky name, just what makes QuEChERS a good extraction technique for the complicated matrices of cannabis products? By understanding the chemistry behind the extraction and the methodology’s history, cannabis laboratories can better implement the technology and educate their workforce.

QuEChERS salt blends can be packed into mylar pouches for use with any type of centrifuge tubes

In 2003, a time when only eight states had legalized the use of medical cannabis, a group of four researchers published an article in the Journal of AOAC International that made quite the impact in the residue monitoring industry. Titled Fast and Easy Multiresidue Method Employing Acetonitrile Extraction/Partitioning and “Dispersive Solid-Phase Extraction” for the Determination of Pesticide Residues in Produce, Drs. Michael Anastassiades, Steven Lehotay, Darinka Štajnbaher and Frank Schenck demonstrate how hundreds of pesticides could be extracted from a variety of produce samples through the use of two sequential steps: an initial phase partitioning followed by an additional matrix clean up. In the paper’s conclusion, the term QuEChERS was officially coined. In the fourteen years that have followed, this article has been cited over 2800 times. Subsequent research publications have demonstrated its use in matrices beyond food products such as biological fluids, soil and dietary supplements for a plethora of analytes including phthalates, pharmaceutical compounds and most recently cannabis.

QuEChERS salts can come prepacked into centrifuge tubes

The original QuEChERS extraction method utilized a salt blend of 4 g of magnesium sulfate and 1 g of sodium chloride. A starting sample volume of 10 g and 10 mL of acetonitrile (ACN) were combined with the above-mentioned salt blend in a centrifuge tube. The second step, dispersive solid phase extraction (dSPE) cleanup, included 150 mg of magnesium sulfate and 25 mg of primary secondary amine (PSA). Subsequent extraction techniques, now known as AOAC and European QuEChERS, suggested the use of buffered salts in order to protect any base sensitive analytes that may be critical to one’s analysis. Though the pH of the extraction solvent may differ, all three methods agree that ACN should be used as the starting organic phase. ACN is capable of extracting the broadest range of analytes and is compatible with both LC-MS/MS and GC-MS systems. While ethyl acetate has also been suggested as a starting solvent, it is incompatible with LC-MS/MS and extracts a larger amount of undesirable matrix components in the final aliquot.

All laboratories, including cannabis and food safety settings, are constantly looking for ways to decrease their overhead costs, batch out the most samples possible per day, and keep their employees trained and safe. It is not a stretch to say that QuEChERS revolutionized the analytical industry and made the above goals tangible achievements. In the original publication, Anastassiades et al. established that recoveries of over 85% for pesticides residues were possible at a cost as low as $1 per ten grams of sample. Within forty minutes, up to twelve samples were fully extracted and ready to be analyzed by GC-MS, without the purchase of any specialized equipment. Most importantly, no halogenated solvents were necessary, making this an environmentally conscious concept. Due to the nature of the cannabis industry, laboratories in this field are able to decrease overall solvent usage by a greater amount than what was demonstrated in 2003. The recommended starting sample for cannabis laboratories is only one gram of flower, or a tenth of the starting volume that is commonly utilized in the food safety industry. This reduction in sample volume then leads to a reduction in acetonitrile usage and thus QuEChERS is a very green extraction methodology.

The complexity of the cannabis matrix can cause great extraction difficulties if proper techniques are not used

As with any analytical method, QuEChERS is not perfect or ideal for every laboratory setting. Challenges remain in the cannabis industry where the polarity of individual pesticides monitored in some states precludes them from being amenable to the QuEChERS approach. For cannabis laboratories looking to improve their pesticide recoveries, decrease their solvent usage and not invest their resources into additional bench top equipment, QuEChERS is an excellent technique to adopt. The commercialization of salt blends specific for cannabis flowers and edibles takes the guesswork out of which products to use. The growth of cannabis technical groups within established analytical organizations has allowed for better communication among scientists when it comes to best practices for this complicated matrix. Overall, it is definitely worth implementing the QuEChERS technique in one’s cannabis laboratory in order to streamline productivity without sacrificing your results.

The Practical Chemist

Pesticide Analysis in Cannabis and Related Products: Part 3

By Julie Kowalski

No Comments

As mentioned in Part 1, pesticides residue analysis is very challenging especially considering the complexity of cannabis and the variety of flower, concentrates and infused products. In addition, pesticides are tested at low levels typically at parts-per-billion (ppb). For example, the food safety industry often uses 10 ppb as a benchmark limit of quantification. To put that in perspective, current pesticides limits in cannabis range from 10 ppb default (Massachusetts Regulatory Limit) to a more typical range of 100 ppb to 2 ppm in other states. Current testing is also complicated by evolving regulations.

Despite these challenges, adaptation of methods used by the food safety industry have proved successful for testing pesticides in cannabis. These methods typically rely on mass spectrometric detection paired with sample preparation methods to render the sample clean enough to yield quality data.

Pesticide Analysis Methods: Sample preparation and Analytical Technique Strategy

Generally, methods can be divided into two parts; sample preparation and analytical testing where both are critical to the success of pesticide residue testing and are inextricably linked. Reliance on mass spectrometric techniques like tandem mass spectrometry and high resolution accurate mass (HRAM) mass spectrometry is attributed to the substantial sensitivity and selectivity provided. The sensitivity and selectivity achievable by the detector largely dictates the sample preparation that will be required. The more sensitive and selective the detector, the less rigorous and resource intensive sample preparation can be.

Analytical technique: Gas and Liquid Chromatography Tandem Mass Spectrometry

The workhorse approach for pesticide residue analysis involves using gas chromatography and liquid chromatography tandem mass spectrometry (MS/MS) in the ion transition mode. This ion transition mode, often referred to as multiple reaction monitoring (MRM) or selected reaction monitoring (SRM), adds the selectivity and sensitivity needed for trace level analysis. Essentially, a pesticide precursor ion is fragmented into product ions. The detector monitors the signal for a specified product ion known to have originated from the pesticide precursor ion. This allows the signal to be corrected, associated with the analyte and not with other matrix components in the sample. In addition, because only ions meeting the precursor/product ion requirements are passed to the detector with little noise, there is a benefit to the observed signal to noise ratio allowing better sensitivity than in other modes. Even though ion transitions are specific, there is the possibility a matrix interference that also demonstrates that same ion transition could result in a false positive. Multiple ion transitions for each analyte are monitored to determine an ion ratio. The ion ratio should remain consistent for a specific analyte and is used to add confidence to analyte identification.

The best choice for pesticide analysis between gas chromatography (GC) and liquid chromatography (LC) is often questioned. To perform comprehensive pesticide screening similar to the way the food safety market approaches this challenge requires both techniques. It is not uncommon for screening methods to test for several hundred pesticides that vary in physiochemical properties. It may be possible that with a smaller list of analytes, only one technique will be needed but often in order to reach the low limits for pesticide residues both GC and LC are required.

Analytical technique: Sample Preparation

Less extensive sample preparation is possible when combined with sensitive and selective detectors like MS/MS. One popular method is the QuEChERS approach. QuEChERS stands for Quick, Easy, Cheap, Effective, Rugged and Safe. It consists of a solvent extraction/salting out step followed by a cleanup using dispersive solid phase extraction. Originally designed for fruit and vegetable pesticide testing, QuEChERS has been modified and used for many other commodity types including cannabis. Although QuEChERS is a viable method, sometimes more cleanup is needed and this can be done with cartridge solid phase extraction. This cleanup functions differently and is more labor intensive, but results in a cleaner extract. A cleaner extract helps to secure quality data and is sometimes needed for difficult analyses.

Annual AOCS Meeting Spotlights Cannabinoid Analytics

By Aaron G. Biros

No Comments

The AOCS Annual Meeting is an international science and business forum on fats, oils, surfactants, lipids and related materials. The American Oil Chemist’s Society (AOCS) is holding their meeting in Orlando, Florida from April 30 to May 3, 2017. Last year’s meeting included discussions on best practices and the pros and cons of different extraction techniques, sample preparation, proficiency testing and method development, among other topic areas.

Posters on display for the duration of the Annual Meeting will discuss innovative solutions to test, preparing samples, discovering new compounds and provide novel information about the compounds found in cannabis. David Egerton, vice president of technical operations at CW Analytical (a cannabis testing laboratory in Oakland, CA), is preparing a poster titled Endogenous Solvents in Cannabis Extracts. His abstract discusses testing regulations focusing on the detection of the presence of solvents, despite the fact that endogenous solvents, like acetone and lower alcohols, can be found in all plant material. His study will demonstrate the prevalence of those compounds in both the plant material and the concentrated oil without those compounds being used in production.

The conference features more than 650 oral and poster presentations within 12 interest areas. This year’s technical program includes two sessions specifically designed to address cannabinoid analytics:

Lab Proficiency Programs and Reference Samples

How do you run a lab proficiency program when you cannot send your samples across state lines? What constituents do you test for when state requirements are all different? Are all pesticides illegal to use on cannabis? What pesticides should be tested for when they are mostly illegal to use? How do you analyze proficiency results when there are no standard methods? Learn about these and other challenges facing the cannabis industry. This session encourages open and active discussion, as the cannabis experts want to hear from you and learn about your experiences.

Method Development

The need for high-quality and safe products has spurred a new interest in cannabinoid analytics, including sample preparation, pesticide, and other constituent testing. In this session, a diverse group of scientists will discuss developing analytical methods to investigate cannabis. Learn the latest in finding and identifying terpenes, cannabinoids, matrix effects, and even the best practice for dissolving a gummy bear.

Cynthia Ludwig speaking at last year's meeting — Cynthia Ludwig speaking at last year’s meeting

Cynthia Ludwig, director of technical services at AOCS, says they are making great progress in assembling analytical methods for the production of the book AOCS Collection of Cannabis Analytical Methods. “We are the leading organization supporting the development of analytical methods in the cannabis industry,” says Ludwig. “Many of the contributors in that collection will be presenting at the AOCS Annual Meeting, highlighting some of the latest advances in analyzing cannabis.” The organization hopes to foster more collaboration among those in the cannabis testing industry.

In addition to oral and poster sessions, the 2017 Annual Meeting will feature daily networking activities, more than 70 international exhibitors, two special sessions, and a Hot Topics Symposia which will address how current, critical issues impact the future of the fats and oils industry.

Colorado Cannabis Lab Methods Updated for Microbial Testing

By Aaron G. Biros

No Comments

The Colorado Department of Public Health and Environment’s (CDPHE) Marijuana Laboratory Inspection Program issued a bulletin on January 30^th regarding updates required for licensed cannabis testing labs. The updated method for microbial contaminant testing includes a longer incubation period in yeast and mold testing.

“After careful consideration of emerging data regarding the use and effectiveness of 3M Total Yeast and Mold Rapid Petrifilms in marijuana, CDPHE has concluded that 48 hours is not a sufficient incubation period to obtain accurate results,” the letter states. “Based upon the review of this information, marijuana/marijuana products require 60-72 hours of incubation as per the manufacturer’s product instructions for human food products, animal feed and environmental products.” The letter says they determined it was necessary to increase the incubation period based on data submitted from several labs, along with a paper found in the Journal of Food Protection.

An incubator (Right) at TEQ Analytical Labs

According to Alexandra Tudor, manager of the microbiology department at TEQ Analytical Labs (a cannabis testing lab in Aurora, CO), the update is absolutely necessary. “The incubation time extension requirement from CDPHE offers more reliable and robust data to clients by ruling out the possibility of a false yeast and mold result during analysis,” says Tudor.

Alexandra Tudor, microbiology department manager at TEQ Analytical Labs

“3M, the maker of Petrifilm, recommends an incubation time of 48-72 hours, but during TEQ’s method validation procedure, we learned that 48-hour incubation was not sufficient time to ensure accurate results. Although some laboratories in industry had been incubating for the minimum amount of time recommended by the manufacturer, the 48-hour incubation time does not provide a long enough window to ensure accurate detection of microbiological contaminants present in the sample.” Tudor says the update will help labs provide more confident results to clients, promoting public health sand safety.

As a result of the update in testing methodology, cultivators and infused product manufacturers in Colorado need to submit a batch test for yeast and mold. The point of requiring this batch test is to determine if the producer’s process validation is still effective, given the new yeast and mold testing method.

Florida On Path to Implement Medical Cannabis Legalization

By Aaron G. Biros

No Comments

Voters in Florida passed Amendment 2 last year with an overwhelming majority of over 70%. The constitutional amendment went into effect on January 3^rd this year and regulators have until July 3^rd to promulgate the rules.

The Florida Department of Health set up the Office of Compassionate Use (OCU) in July of 2014 after the passing of the so-called Charlotte’s Web measure (HB 843). That bill allows use of low THC/high CBD cannabis for treating seizures. The OCU is charged with the task of writing and implementing medical cannabis rules. Ongoing public hearings and workshops at the Department of Health (DOH) are meant to give stakeholders the opportunity to chime in on the proposed rules.

On January 17^th, the DOH published proposed rules and announced public hearings, seeking input from the public on the matter. The OCU is required to implement rules consistent with Amendment 2, but they would defer to the legislature if a bill were passed, promulgating rules consistent with Amendment 2 and the bill.

After the passing of Amendment 2, Sen. Jeff Brandes (R-St. Petersburg) filed SB614, a bill that establishes four license categories instead of the currently required vertically integrated business model. Notably, Sen. Brandes’ bill requires laboratory batch testing, whereas other proposed rules do not include such a measure. Sen. Brandes sees the DOH’s proposed rules as more of the same from the current medical program, according to a quote from FloridaPolitics.com. “Any proposal which seeks to mold the spirit of Amendment 2 into the narrow and flawed law on the books today should be rejected, and a more comprehensive strategy must take priority,” says Sen. Brandes. “I will support no bill, nor any rule, that maintains the established state sanctioned cartel system we have today, and I urge my colleagues to join me in proposing a free market solution for Florida.” He is referring to the seven licensed nurseries from the low THC/high CBD medical program, all of which are vertically integrated.

Matthew Ginder, senior counsel of the cannabis practice at Greenspoon Marder — Matthew Ginder, senior counsel in the cannabis practice at Greenspoon Marder

According to Matthew Ginder, senior counsel in the cannabis law practice at Greenspoon Marder, the biggest question for the legislature is how many licenses will they issue and what kind of structures are required for the licensees. Another big issue is the process by which patients access medical cannabis through their physicians. “The current program requires physicians to register as the orderer of medical cannabis, specify dosing and order medical devices, which is highly uncommon in other state programs,” says Ginder. “Sen. Brandes’ bill removes these requirements and is more consistent with other states by requiring a physician’s recommendation.” He says that bill would create four licenses: cultivation, processing transportation and retail.

Sen. Robert Bradley (R-5^th District) also filed legislation (SB 406) to implement Amendment 2, but this bill is very different from Sen. Brandes’ bill. “Bradley’s bill is built upon the statutory framework that is already in place,” says Ginder. “Bradley’s is keeping vertical integration intact, seeking to also limit the amount of vertically integrated license based on a patient ratio of about 20,000 registered patients per license issued.” Bradley’s bill does not provide for independent lab testing requirements. Some might characterize Bradley’s bill as more of the same, allowing for the consolidation of existing monopolies.

Ginder says these are just two bills from the Senate, the House still has not proposed any bills. “We will most likely see more bills,” says Ginder. “We still don’t know what iteration of the bill or what language might be adopted and you can expect them to change as it moves through the committees.” With the legislative session beginning on March 7^th, we can expect to see these bills debated on the floor and likely the filing of other legislation.

On February 1^st, Greenspoon Marder announced the launch of their Organization for Safe Cannabis Regulation (OSCR) in Florida. By hiring lobbyists and making contributions to certain political candidates, the OSCR aims to advocate for a broad and fair marketplace, specifically “advocating for laws that create independently “registered” entities that perform specific functions along the production and distribution chain.”

Hoban Law Group Files Lawsuit Against DEA

By Aaron G. Biros

The Hoban Law Group filed a petition on behalf of three clients against the DEA in the U.S. Court of Appeals for the Ninth District on January 13^th, according to a press release. The clients represented by Hoban Law Group in the suit are Hemp Industries Association, RMH Holdings, LLC and Centuria Natural Foods, Inc. The companies are based in California, Colorado and Nevada respectively and are all active in the legal hemp trade. The press release says RMH Holdings “sources its products from industrial hemp lawfully cultivated pursuant to the Agricultural Act of 2014 (also known as the Farm Bill).”

In December, the DEA published a ‘Final Rule’ that classifies cannabis-derived extracts, such as CBD oil, in their own category with a code number to “better track these materials and comply with treaty provisions.” The announcement by the DEA ultimately serves to make any cannabis extract a Schedule 1 narcotic. “Extracts of marihuana will continue to be treated as Schedule I controlled substances,” says the document.

Bob Hoban, managing partner of Hoban Law Group says the action is clearly beyond the DEA’s authority. “This Final Rule serves to threaten hundreds, if not thousands, of growing businesses, with massive economic and industry expansion opportunities, all of which conduct lawful business compliant with existing policy as it is understood and in reliance upon the Federal Government,” says Hoban.

The lawsuit states that they want a judicial review of the DEA’s actions “on the grounds that the Final Rule is (1) arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with law, e.g. the CSA, the Farm Bill, and the DEA’s regulations; (2) contrary to constitutional right, power, privilege, or immunity; (3) in excess of statutory jurisdiction, authority, or limitations; and, (4) without observance of procedure required by law.” The suit also claims that the ‘Final Rule’ conflicts with other federal laws like the Data Quality Act, Regulatory Flexibility Act and Congressional Review Act.

According to Garrett Graff, associate attorney at Hoban Law Group, the entire Cannabis genus is not unlawful and the DEA is overstepping its authority. “As the Ninth Circuit found in 2003 and 2004 there are certain parts of the plant like the stalk and seed that are congressionally exempted from the Controlled Substances Act and thus the DEA’s rulemaking authority,” says Graff. “By creating a drug code for ‘marihuana extract’, the DEA is saying that they are a controlled substance, but that goes against a number of existing laws.”

The definition of ‘marihuana extract’ under the ‘Final Rule’ also references extracts containing one or more cannabinoids, which goes beyond the realm of cannabis altogether, according to Graff. “The DEA and many other sources have acknowledged and confirmed that cannabinoids can be derived from other varieties of flowers, cacao and other sources, making it virtually impossible to distinguish which cannabinoids would be subject to this drug code,” says Graff. “The DEA’s rule effectively makes the presence of cannabinoids a determinative factor of a controlled substance, which is inconsistent with what Congress has said.”

The petition filed is essentially the initiation or commencing of a lawsuit. Graff says their case is rooted in statute. “We hope to accomplish a striking of the rule, permanent injunction of the rule and for the DEA to engage in the appropriate processes and procedures when making rules in the future,” says Graff. “Alternatively, an amendment to the rule to make the definition of ‘marihuana extract’ consistent with existing law and reflect those portions and varieties of the plant which are in fact lawful could be considered.” It may still be roughly 30 days before the DEA responds with briefing and possibly an oral argument to follow on the various issues surrounding the petition, says Graff. The Ninth Circuit petition, including briefings and hearings, is likely to take at least several months.
