Pesticide Testing: Methods, Strategies & Sampling

By Charles Deibel

Editor’s Note: The following is based on research and studies performed in their Santa Cruz Lab, with contributions from Mikhail Gadomski, Lab Manager, Ryan Maus, Technical Services Analyst, Dr. Laurie Post, Director of Food Safety & Compliance, Andy Sechler, Lab Director, Toby Astill, Senior Business Development Leader at Perkin Elmer and Charles Deibel, President of Deibel Cannabis Labs.

Pesticides represent the leading cause of batch failures in the cannabis industry. They are also the hardest tests to run in the laboratory, even one equipped with state-of-the-art equipment. The best instruments on the market are HPLC and GC dual mass spectrometer detectors, called “HPLC-qqq”, “GC-qqq,” or just triple quads.

As non-lab people, we envision a laboratory that can take a cannabis sample, inject it into a triple quad and have the machine quickly and effortlessly print out a report of pesticide values. Unfortunately, this is far from reality. The process is much more hands on and complex.In the current chemistry lab, trained analysts have to first program the triple quads to look for the pesticides of concern; in cannabis pesticide testing, this is done by programming the first of two mass spectrometers to identify a single (precursor) mass that is characteristic of the pesticide in question. For BCC requirements in California, this has to be done for all 66 pesticides, one at a time.

Next, these precursor ions are degraded into secondary chemicals called the “product” ions, also called transition ions. The second of the two mass spectrometers is used to analyze these transition ions. This process is graphed and the resulting spectrum is analyzed by trained chemists in the lab, pesticide by pesticide, for all the samples processed that day. If the lab analyzes 10 samples, that translates to 660 spectra to analyze (66 pesticides x 10 samples). When looking at the spectra for each pesticide, the analysts must compare the ratios of the precursor ions to the product ions.

Confirmation Testing

If these spectra indicate a given pesticide may be present, the chemists must then compare the ratios between the precursor and the products. If these ratios are not what is expected, then the analyst must perform confirmation testing to prove the precursor mass either is or is not the pesticide of concern. If the ratios are not what is expected, it means the molecule is similar to the pesticide in question, but may not be that pesticide. This confirmatory testing is key to producing accurate results and not failing batches when dealing with closely related chemicals. This process of analyzing spectra is done in all labs that are performing pesticide testing. In this fledgling industry, there are few published cannabis pesticide methods.

The need for this type of confirmation testing doesn’t happen all of the time, but when it does, it will take longer than our targeted three-day turn-around time. In the picture above, one precursor mass is ionized into several product masses; but only two are large enough to be used for comparison. In this hypothetical situation, two product masses are produced for every one precursor, the expected ion abundance ratio should be less than 30%. When performing any confirmatory testing, if the ion abundance ratio is >30%, it means the original precursor molecule was not the pesticide of concern. For example, if the ion abundance ratio was 50%, then the original molecule broke down into too many parts; it was not the pesticide we were looking for. This ion abundance ratio threshold was established by FANCO, the international organization that sets guidelines for all pesticide testing.

Testing Strategies

Methodology: In this fledgling industry, there are few published cannabis pesticide methods. The identification of the precursor mass and product ions are not always published, leaving labs to research which ions should be used. This adds to the potential for differences between lab results. Once selected, labs should validate their research, through a series of experiments to ensure the correct precursor and transition (product) ions are being used in the method.

Sample Preparation: Beyond the time-consuming work that is required to develop sound pesticide methods, the extraction step is absolutely critical for credible results. If the pesticides aren’t fully extracted from the cannabis product, then the results will be lower than expected. Sample preparations are often not standardized between labs, so unless a given extraction technique is validated for accuracy, there is the possibility for differences between labs.

Getting a Representative Sample

The current California recommended amount of sample is one gram of product per batch. Batch sizes can vary greatly and it is entirely likely that two different one gram samples can have two different results for pesticides. Has the entire plant been evenly coated with exactly the same amount of pesticide onto every square inch of its leaves? No, probably not. That is why it is imperative to take a “random” sample, by taking several smaller samples from different areas of the entire batch.

Sampling Plans: We can learn a lot from the manufacturing and sampling best practices developed by the food industry through the years. If a food manufacturer is concerned with the possibility of having a bacteria pathogen, like Salmonella, in their finished product, they test the samples coming off their production lines at a statistically relevant level. This practice (theory) is called the sampling plan and it can easily be adapted to the cannabis industry. The basic premise is that the more you test, the higher your likelihood of catching a contaminate. Envision a rectangular swimming pool, but instead of water, it’s filled with jello. In this gelatinous small pool, 100 pennies are suspended at varying levels. The pennies represent the contaminates.

Is the pool homogenized? Is jello evenly represented in the entire pool? Yes.

Is your concentrate evenly distributed in the extraction vessel? Yes. The question is, where are the pennies in that extraction vessel? The heavy metals, the microbial impurities and the pesticides should be evenly distributed in the extraction vessel but they may not be evenly represented in each sample that is collected. Unfortunately, this is the bane of the manufacturing industry and it’s the unfortunate reality in the food industry. If you take one random cup of jello, will you find the penny? Probably not. But it you take numerous 1 cup samples from random areas within the batch, you increase your chances of finding the contaminate. This is the best approach for sampling any cannabis product.

The best way to approve a batch of cannabis product is to take several random samples and composite them. But you may need to run several samples from this composite to truly understand what is in the batch. In the swimming pool example, if you take one teaspoon scoop, will you find one of the pennies? The best way to find one of the pennies is to take numerous random samples, composite them and increase the number of tests you perform at the lab. This should be done on any new vendor/cultivator you work with, in order to help establish the safety of the product.

Illinois Legislators To Introduce Legalization Bill

By Aaron G. Biros

No Comments

It is not news that Illinois Governor J.B. Pritzker favors recreational cannabis legalization. But State Senator Heather Steans (Chicago-D) and State Representative Kelly Cassidy (Chicago-D) introducing a formal bill to legalize recreational cannabis is certainly news. With what they hope will be bipartisan support in the legislature and a Governor on their side, Illinois seems poised to pass legislation legalizing recreational cannabis for adults.

According to the Herald & Register, State Sen. Steans says that public opinion polls show that roughly two-thirds of voters in Illinois favor recreational legalization. “We have a huge opportunity in Illinois to do this right and carefully,” Steans told an audience at a town hall meeting in Springfield, IL yesterday. From what the lawmakers told the public during that town hall meeting, the legislation sounds like it mirrors programs in other states.

The bill “would allow Illinoisans 21 and older to purchase and possess up to 30 grams, or about 1 ounce, of marijuana,” Steans and Cassidy said. “Nonresidents would be able to buy and possess half that amount. Use of the drug in public wouldn’t be allowed.” The bill would expunge previous criminal records with respect to cannabis, make it harder for minors to access it and raise an estimated $350 million to $750 million, providing funding for “community development of impoverished neighborhoods,” says Cassidy. “If we don’t address the social-justice issues of this, if we don’t address the collateral consequences of the ‘war on drugs,’ we will have failed,” Cassidy added. The bill would also allow people to grow up to five plants at home, would not allow for public or social consumption, and municipalities, employers and landlords would be able to prohibit possession and use, according to the lawmakers.

In 2015, the state legalized medical cannabis and there are roughly 42,000 patients currently in the medical cannabis program, with roughly 40 qualifying conditions approved for use. Some critics have argued, according to the Chicago Tribune, that before the state legalizes recreational use for adults, they should first expand the list of qualifying conditions for patients. This would provide greater access to those in need while the state implements a regulatory framework for recreational use, which could take upwards of a year to establish the program.

Cannabis Legalization in Massachusetts: An Interview with Steven Hoffman, Chairman of the Cannabis Control Commission

By Aaron G. Biros

No Comments

On February 13 at the upcoming Seed To Sale Show in Boston, MA, Steven Hoffman, Chairman of the Cannabis Control Commission of Massachusetts, will deliver a keynote discussion. Hoffman will sit down with National Cannabis Industry Association (NCIA) Executive Director Aaron Smith to discuss the first few months of recreational legalization, challenges and the path forward for the state. We caught up with Hoffman to hear about some of the biggest obstacles and successes when it came to standing up a regulated adult-use cannabis market.

On November 8, 2016, voters in Massachusetts ushered in a new era for the East Coast, when they passed a ballot initiative to legalize adult-use cannabis. Almost immediately after that, the Massachusetts Legislature put a hold on implementation in order to study the issues and revise the legislation, which was ultimately signed in July of 2017. That September, Steven Hoffman and his colleagues at the Cannabis Control Commission were appointed to figure out how the state should regulate the market, enforce its regulations and roll out the new adult-use program.

The Commission was tasked with creating something brand new, without a roadmap in place and developing rules around some very contentious issues. “I think the biggest obstacle was that we were doing something unprecedented,” says Hoffman. “Every state is different demographically and the laws differ state to state, and we got a lot of help from other states sharing their experiences with us, but we were still going down an uncharted path for Massachusetts.”

Hoffman told us the very first thing they needed to do in 2017 was conduct listening sessions in which the commissioners listened to citizens for recommendations and heard people’s thoughts on cannabis legalization. “We did that immediately. We needed to conduct a process that was transparent, thoughtful and inclusive,” says Hoffman. “We then, in public, debated policies around adult-use marijuana regarding licensing processes, criteria and enforcement.”

They debated policies in a public forum for four days and came back the following week to embed their decisions in draft regulations that were submitted to the Secretary of State in December 2017. Then, they had 10 more public hearings, made some modifications to the rules, and promulgated a final version of the adult-use regulations in March 2018, keeping everything as transparent and inclusive as possible. “I don’t think anyone has been critical of that process behind it,” says Hoffman.

Certain pieces of the regulations stand out as particularly inclusive and progressive for Massachusetts’ cannabis program. For example, certain mandates encourage diversity and support communities affected by the drug war. Hoffman says the Commission couldn’t take credit for those completely because their objectives are explicit in the legislation, however, the agency still made sure the state followed through. “The mandate said the industry should look like the state of Massachusetts in terms of our diversity,” says Hoffman. That includes creating a diverse industry with respect to ethnicity, gender, LGBTQ, veteran and disabled participation. Additionally, he added, “it was a very explicit set of requirements that those communities who were disproportionally harmed by the drug war are full participants in the new industry we set up. Those were both legislative mandates, so we take them very seriously and I wouldn’t have taken this appointment if I didn’t think it was absolutely essential.”

You can expect to hear more from Hoffman on this and other matters related to implementing cannabis regulations at the upcoming Seed To Sale Show in Boston, MA, February 12-13, 2019. On November 20, 2018, the first adult-use dispensaries in the state opened their doors for business and began selling cannabis. Hoffman says he is most proud of their rollout of the program as well as the transparency and inclusiveness through which they conducted the process. “I think this is a very controversial issue; the voters approved this issue by 53-47%,” says Hoffman. “No matter what we do, we won’t make everyone happy, but we’ve done everything possible to allow people to participate and feel like they’ve been listened to. We made our decisions publicly and transparently.”

Beyond that, the Commission wanted to take their time to make sure things were done the right way the first time. “From day one, we decided we were going to do this right rather than meet an arbitrary timeline,” says Hoffman. “It’s gradual, it’s maybe slower than some people would like, but our rollout has been well-received and relatively smooth. I think a gradual and thoughtful process, not focused on a deadline, went very well. Hopefully we have given other states a model when they plan their own rollout.”

Hoffman wouldn’t comment on whether or not he would encourage other states down a similar path, but he did say they could probably learn a thing or two from them. “I expect other states will do what we did,” says Hoffman. “They will talk to other states ahead of them like us and hopefully will benefit from learning from our experiences. I don’t know what the laws will look like but I expect other states need to make it work for them specifically.”

I Was Wrong… und das ist auch gut so!

By Dr. Markus Roggen

3 Comments

I was wrong. And that’s a good thing! Based on all available data, I assumed that evaporating ethanol from a cannabis oil/ethanol solution would result in terpene loss. As it turns out, it doesn’t. There are so many beliefs and assumptions about cannabis: Cannabis cures cancer!¹ Smoking cannabis causes cancer!² Sativas help you sleep; Indicas make you creative!^3,4CBD is not psychoactive!⁵ But are these ‘facts’ backed by science? Have they been experimentally tested and validated?

I postulated a theory, designed experiments to validate it and evaluated the results. Simply putting “cannabis backed by science” on your label does not solve the problem. Science is not a marketing term. It’s not even a fixed term. The practice of science is multifaceted and sometimes confusing. It evolved from the traditional model of Inductivism, where observations are used in an iterative process to refine a law/theory that can generalize such observations.⁶ Closely related is Empiricism, which posits that knowledge can only come from observation. Rationalism, on the other hand, believes that certain truths can be directly grasped by one’s intellect.⁷ In the last century, the definition of science was changed from the method by which we study something, such as Inductivism or Rationalism, and refocused on the way we explain phenomena. It states that a theory should be considered scientific if, and only if, it is falsifiable.⁸ All that means is that not the way we study something is what makes it scientific, but the way we explain it.

I wonder how can we use empirical observations and rational deliberations to solve the questions surrounding cannabis? And more importantly, how can we form scientific theories that are falsifiable? Cannabis, the plant, the drug, has long been withheld from society by its legal status. As a result, much of what we know, in fact, the entire industry has thrived in the shadows away from rigorous research. It’s time for this to change. I am particularly concerned by the lack of fundamental research in the field. I am not even talking about large questions, like the potential medical benefit of the plant and its constituents. Those are for later. I’m talking about fundamental, mundane questions like how many lumens per square centimetre does the plant need for optimal THC production? What are the kinetics of cannabis extraction in different solvents? What are the thermodynamics of decarboxylation? Where do major cannabinoids differ or align in terms of water solubility and viscosity?

The lack of knowledge and data in the cannabis field puts us in the precarious position of potentially chasing the wrong goals, not to mention wasting enormous amounts of time and money. Here’s a recent example drawn from personal experience:Certainly, I cannot be the only one who has made an incorrect assumption based on anecdotes and incomplete data?

Some of the most common steps in cannabis oil production involve ethanol solutions. Ethanol is commonly removed from extraction material under reduced pressure and elevated heat in a rotary evaporator. I expected that this process would endanger the terpenes in the oil – a key component of product quality. My theory was that volatile terpenes⁹ would be lost in the rotary evaporator during ethanol¹⁰ removal. The close values of vapor pressure for terpenes and ethanol make this a reasonably assumed possibility.¹¹ In the summer of 2018, I finally got the chance to test it. I designed experiments at different temperatures and pressures, neat and in solution, to quantify the terpene lost in ethanol evaporation. I also considered real life conditions and limitations of cannabis oil manufacturers. After all the experiments were done, the results unequivocally showed that terpenes do not evaporate in a rotary evaporator when ethanol is removed from cannabis extracts.¹² As it turns out, I was wrong.

We, as an industry, need to start putting money and effort into fundamental cannabis research programs. But, at least I ran the experiments! I postulated a theory, designed experiments to validate it and evaluated the results. At this point, and only this point, can I conclude anything about my hypothesis, even if that is that my working theory needs to be revised. Certainly, I cannot be the only one who has made an incorrect assumption based on anecdotes and incomplete data?

There is a particular danger when using incomplete data to form conclusions. There are many striking examples in the medical literature and even the casual observer might know them. The case of hormone replacement therapy for menopause and the associated risks of cardiovascular diseases showed how observational studies and well-designed clinical trials can lead to contradicting results.¹³ In the thirties of the last century, lobotomy became a cure-all technique for mental health issues.¹⁴ Dr. Moniz even won the Nobel Prize in Medicine for it.¹⁵ And it must come as no surprise when WIRED states “that one generation’s Nobel Prize-winning cure is another generation’s worst nightmare.”¹⁶ And with today’s knowledge is impossible to consider mercury as a treatment for syphilis, but that is exactly what it was used as for many centuries.¹⁷ All those examples, but the last one in particular should “be a good example of the weight of tradition or habit in the medical practice, […] of the necessity and the difficulties to evaluate the treatments without error.”¹⁸ There is the danger that we as cannabis professionals fall into the same trap and believe the old stories and become dogmatic about cannabis’ potential.

We, as an industry, need to start putting money and effort into fundamental cannabis research programs. That might be by sponsoring academic research,¹⁹ building in-house research divisions,²⁰ or even building research networks.²¹ I fully believe in the need for fundamental cannabis research, even the non-sexy aspects.²² Therefore, I set up just that: an independent research laboratory, focused on fundamental cannabis research where we can test our assumptions and validate our theories. Although, I alone cannot do it all. I likely will be wrong somewhere (again). So, please join me in this effort. Let’s make sure cannabis science progresses.

Cannabis Reform Comes To Africa

By Marguerite Arnold

No Comments

For those familiar with the tragic history of apartheid in South Africa up until the end of the 1980’s, Lesotho is a country long associated with terrible political and economic repression. Also known as the “Kingdom in the Sky” because of its stunning geography, the tiny, landlocked country is literally inside and completely surrounded by South Africa. During the apartheid regime, Lesotho was a place where “vice industries” like prostitution and gambling were allowed to flourish by a much more conservative surrounding political regime. Much like Indian reservations in the U.S., in fact.

Even today, diamonds and water are the country’s top exports although tourism, including skiing, is still a major underpinning of the country’s domestic economy.

Moving forward into the 21st century and much like American Indians, the mountainous, impoverished country is looking at the cannabis trade to create a national income of global worth. In 2017, the country became the first on the African continent to actually legalize cultivation for medical purposes, as well as export. Illicit cultivation, mostly bound for the black market, however, has boomed since the end of the apartheid regime.

The country’s high altitude and fertile soils untainted with pesticides, makes Lesotho an ideal place to grow even outdoor crops. And as a result, the country has also begun to attract foreign capital interested in the production and export of finished products rather than the raw plant material. Several big Canadian producers, in fact, have already established commercial operations.

2018 Was The “Year For Cannabis” In South Africa

As a result of Lesotho’s lead, neighboring countries are now also following suit on the legalization front. Zimbabwe, just to the north of South Africa, has also legalized cultivation for medical purposes although local farmers have been slow to seize the opportunity. Malawi is also moving towards some kind of cannabis reform along with Nigeria, Ghana and Swaziland. And of course, to the north, Morocco, already established globally for illicit cannabis and hashish production (much of it making its way into Europe as it has for literally hundreds of years at this point) is also teetering on some kind of reform.

In South Africa itself, the economic powerhouse of the continent, the personal cultivation and smoking of cannabis (for both medicinal and recreational reasons) was enshrined as a constitutional right as of September 2018. That said, commercial production and sales for recreational use remains illegal. As in other places, the licensing process in South Africa has held up the medicinal and recreational market already on the table if not in the room. And most locals cannot afford the licensing fees.

That said, there is already a commercial cannabis beer brewing company called Durban Poison which rushed into the space as soon as the constitutional question changed in South Africa. The country is the biggest beer market in Africa. And there are competitors already lining up for similar opportunities of both the medical and recreational kind.

Including South Africa, according to estimates, there are already 10,000 tons of product produced (mostly illicitly) across the continent. Much as in other places, this “green gold” has financed many of the regional wars of the last sixty years. For this reason, apart from the economic benefits that legalization brings, it may well be that the first big continental competition on the cannabis front that enters first world markets, will be African rather than Latin American (or even Chinese).

Legalization and regulation will help stamp out the illicit financing of guerrilla wars and devastation, bringing more political and economic stability. It may also provide one of the best regional economic incentives to stop rare wildlife poaching.

Medical and Recreational Opportunities Loom Large- But So Do Liabilities

But for all the potential of the future, now comes the hard part (as in other regions of the world where reform has come). Stamping out the black market and establishing licencing and other regulations (of all kinds, starting with GMP). Plus of course, because this is Africa, attracting capital at reasonable rates, and establishing legitimate distribution domestically, plus trade routes for global export. Including of course, both to Europe and Australia.

Medical research in Africa is also likely to be an interesting question especially given the impact of cannabis on infection. Africa is home to some of the more dire contagious natural diseases known to man. This plant, in other words, produced locally, might also be applied locally to help manage everything from Malaria to Ebola. If not become a staple in the medical kits distributed by foreign aid organizations. That of course, will take reform at the UN level. But even this conversation, at this point, is now moving.

That said, as 2019 gets underway, there is not a single continent of the world, much less a region, where cannabis reform has not touched.

Heavy Metals Testing: Methods, Strategies & Sampling

By Charles Deibel

3 Comments

Editor’s Note: The following is based on research and studies performed in their Santa Cruz Lab, with contributions from Mikhail Gadomski, Lab Manager, Ryan Maus Technical Services Analyst, Laurie Post, Director of Food Safety & Compliance, and Charles Deibel, President Deibel Cannabis Labs.

Heavy metals are common environmental contaminants resulting from human industrial activities such as mining operations, industrial waste, automotive emissions, coal fired power plants and farm/house hold water run-off. They affect the water and soil, and become concentrated in plants, animals, pesticides and the sediments used to make fertilizers. They can also be present in low quality glass or plastic packaging materials that can leach into the final cannabis product upon contact. The inputs used by cultivators that can be contaminated with heavy metals include fertilizers, growing media, air, water and even the clone/plant itself.

The four heavy metals tested in the cannabis industry are lead, arsenic, mercury and cadmium. The California Bureau of Cannabis Control (BCC) mandates heavy metals testing for all three categories of cannabis products (inhalable cannabis, inhalable cannabis products and other cannabis and cannabis products) starting December 31, 2018. On an ongoing basis, we recommend cultivators test for the regulated heavy metals in R&D samples any time there are changes in a growing process including changes to growing media, cannabis strains, a water system or source, packaging materials and fertilizers or pesticides. Cultivators should test the soil, nutrient medium, water and any new clones or plants for heavy metals. Pre-qualifying a new packaging material supplier or a water source prior to use is a proactive approach that could bypass issues with finished product.

Testing Strategies

The best approach to heavy metal detection is the use of an instrument called an Inductively Coupled Plasma Mass Spectrometry (ICP-MS). There are many other instruments that can test for heavy metals, but in order to achieve the very low detection limits imposed by most states including California, the detector must be the ICP-MS. Prior to detection using ICP-MS, cannabis and cannabis related products go through a sample preparation stage consisting of some form of digestion to completely break down the complex matrix and extract the heavy metals for analysis. This two-step process is relatively fast and can be done in a single day, however, the instruments used to perform the digestion are usually the limiting step as the digesters run in a batch of 8-16 samples over a 2-hour period.

Only trace amounts of heavy metals are allowed by California’s BCC in cannabis and cannabis products. A highly sensitive detection system finds these trace amounts and also allows troubleshooting when a product is found to be out of specification.

For example, during the course of testing, we have seen lead levels exceed the BCC’s allowable limit of 0.5 ppm in resin from plastic vape cartridges. An investigation determined that the plastic used to make the vape cartridge was the source of the excessive lead levels. Even if a concentrate passes the limits at the time of sampling, the concern is that over time, the lead leached from the plastic into the resin, increasing the concentration of heavy metals to unsafe levels.

Getting a Representative Sample

The ability to detect trace levels of heavy metals is based on the sample size and how well the sample represents the entire batch. The current California recommended amount of sample is 1 gram of product per batch. Batch sizes can vary but cannot be larger than 50 pounds of flower. There is no upper limit to the batch sizes for other inhalable cannabis products (Category II).

It is entirely likely that two different 1 gram samples of flower can have two different results for heavy metals because of how small a sample is collected compared to an entire batch. In addition, has the entire plant evenly collected and concentrated the heavy metals into every square inch of it’s leaves? No, probably not. In fact, preliminary research in leafy greens shows that heavy metals are not evenly distributed in a plant. Results from soil testing can also be inconsistent due to clumping or granularity. Heavy metals are not equally distributed within a lot of soil and the one small sample that is taken may not represent the entire batch. That is why it is imperative to take a “random” sample by collecting several smaller samples from different areas of the entire batch, combining them, and taking a 1 g sample from this composite for analysis.

ERP’s Role in Ensuring Traceability & Compliance in the Cannabis Market

By Daniel Erickson

1 Comment

Recent trends in the cannabis space and media headlines reveal the challenges and complexities of the evolving cannabis industry with regard to traceability and compliance. Keeping abreast of the evolving state of legislative requirements is complex and requires effective procedures to ensure your business will flourish. At the forefront is the need to provide complete seed-to-sale traceability from the cannabis plant to the consumer, increasing the demand for effective tracking and reporting technologies to assure cultivators, manufacturers, processors and dispensaries are able to meet regulatory compliance requirements. An enterprise resource planning (ERP) solution offers a business management solution designed to integrate all aspects from the greenhouse and growing to inventory, recipe/formulation, production, quality and sales, providing complete traceability to meet compliance regulations.

The main force driving cannabusinesses’ adoption of strict traceability and secure systems to monitor the growth, production and distribution of cannabis is the Cole Memorandum of 2013 issued by former US Deputy Attorney General James Cole. The document was designed to prevent the distribution of cannabis to minors, as well as prevent marijuana revenue from being used for criminal enterprises. Due to the non-legal status of cannabis on the federal level, the memo provides guidance for states whose voters have passed legislation permitting recreational or medical cannabis use. If states institute procedures for transparent inventory control and tracking documentation, the memo indicates that the federal government will refrain from interference and/or prosecution. Despite the Trump administration rescinding the memo in early 2018, companies have largely continued to follow its guidelines in an attempt to avoid targeted enforcement of federal law. Local government reporting is a primary reason for strict inventory control, necessitating reliable traceability documentation of the chain-of-custody.

Process metrics within an ERP solution are essential in providing the accountability necessary to meet required cannabis compliance initiatives. With a centralized, streamlined and secure system, each process becomes documented and repeatable – enabling best practices to provide an audit trail for accountability in all cannabis activities. Whether cultivating, extracting, manufacturing or dispensing cannabis, an ERP’s functionality assists with compliance demands to manage and support traceability and other state-level requirements.

An ERP solution solves the traceability and compliance issues faced by the industry by providing inventory control management and best practices that automates track and trace record keeping from seed to consumer. Growers are also implementing cultivation management solutions within their ERP and highly secure plant identification methods to mobilize greenhouse and inventory to support real-time tracking. Monitoring the loss of inventory due to damage, shrinkage, accidentally or purposeful destruction is efficiently documented to assure that inventory is accounted for. Similar to other process manufacturing industries, it is possible to produce tainted or unsafe products, therefore an ERP solution that supports product recall capabilities is fundamental. With a centralized framework for forward and backward lot, serial and plant ID tracking, the solution streamlines supply chain and inventory transactions to further ensure compliance-driven track and trace record keeping is met.

Local government reporting is a primary reason for strict inventory control, necessitating reliable traceability documentation of the chain-of-custody. Data regarding inventory audit and inspection details, complete with any discrepancies, must be reported to a states’ seed-to-sale tracking system to conform with legal requirements. An ERP utilizes cGMP best practices and reporting as safeguards to keep your company from violating compliance regulations. Failure to complete audits and meet reporting guidelines can be detrimental to your bottom line and lead to criminal penalties or a loss of license from a variety of entities including state regulators, auditors and law enforcement agencies. A comprehensive ERP solution integrates with the state-administered traceability systems more easily and reliably as compared to manual or stand-alone systems – saving time, money and detriment resulting from non-compliance.

Similar to other food and beverage manufacturers, the growing market for cannabis edibles can benefit from employing an ERP system to handle compliance with food safety initiatives – encompassing current and future requirements. Producers of cannabis-infused products for recreational and medicinal use are pursuing Global Food Safety Initiative (GFSI) certification, employing food safety professionals and implementing comprehensive food safety practices–taking advantage of ERP functionality and processes currently in place in similarly FDA regulated industries.

As legalization continues and reporting regulations standardize, dynamic cannabis ERP solutions for growers, processors and dispensaries will evolve to meet the demands and allow for operations to grow profitably.In addition to lot, serial and plant ID tracking, tracing a product back to the strain is equally important. An ERP can efficiently trace a cannabis strain from seedling through the final product, monitoring its genealogy, ongoing clone potency, CBD and THC content ratios and other attributes. The health, weight and required growing conditions of each individual plant or group of plants in the growing stages may be recorded throughout the plant’s lifecycle. In addition, unique plant identification regarding the performance of a particular strain or variety, how it was received by the market and other critical elements are tracked within ERP system. This tracking of particular strains assists with compliance-focused labeling and determining the specific market for selling and distribution of cannabis products.

Collecting, maintaining and accessing traceability and compliance data in a centralized ERP system is significant, but ensuring that information is safe from theft or corruption is imperative as well. An ERP solution with a secure platform that employs automated backups and redundancy plans is essential as it uses best practices to ensure proper procedures are followed within the company. User-based role permissions provide secure accessibility restricted to those with proper authorization. This level of security allows for monitoring and recording of processes and transactions throughout the growing stages, production and distribution; ensuring accountability and proper procedures are being followed. Investing in an ERP solution that implements this level of security aids companies in their data assurance measures and provides proper audit trails to meet regulations.

In this ever-changing industry, regulatory compliance is being met by cannabusinesses through the implementation of an ERP solution designed for the cannabis industry. Industry-specific ERP provides functionality to manage critical business metrics, inventory control, local and state reporting and record keeping, and data security ensuring complete seed-to-sale traceability while offering an integrated business management solution that supports growth and competitive advantage in the marketplace. As legalization continues and reporting regulations standardize, dynamic cannabis ERP solutions for growers, processors and dispensaries will evolve to meet the demands and allow for operations to grow profitably.

French Cannabis Reform Is Finally In The Offing

By Marguerite Arnold

No Comments

It is not exactly the storming of the Bastille, but cannabis reform appears to finally be not just in the offing, but crystallizing in the land of the Marseillaise. Why? Apart from the inevitable, particularly now that the European Parliament has put medical reform on a continental agenda?

The first reason is that this is an easy way for the increasingly politically beleaguered French Prime Minister Emmanual Macron to show he is a “man of the people.” In the age of the gilets jaunes or “yellow vests” – protesters on the streets pushing for economic and political justice – a reform of the green kind is just the ticket.

Secondly, French drug laws are still ridiculously harsh. Use or possession of “narcotics” that are not specifically prescribed by a doctor carries up to a $4,000 fine and a year in prison.

The third reason is that politicians and policy reformers are finally getting the message because of another reason also familiar to American reformers. Locking people up for even minor drug offenses (and French law makes no distinction between cannabis and harder drugs) is a societal menace. It costs the government a lot of money to put people in prison. And the police, just as they are in other places, notably Germany, are tired of engaging in this kind of activity. Particularly when a large number of those they end up arresting are actually patients.

Here is the next issue: The drug laws on the books in France date from December 31, 1970. Similar to the U.S., cannabis of course was treated just like heroin and cocaine. Since that period, French drug arrests have steadily increased (making 67.5% of all arrests as of 2016). Convictions for drug offenses have also increased over ten-fold in the last generation (since the turn of the century).Last year, the CBD market was allowed a little room to flourish in the new grey laws around reform

In a country where approximately 700,000 people use cannabis daily, and 1.4 million use it regularly, this is clearly not sustainable on any front. Particularly where cannabis reform is such a potent weapon in a country where the “yellow vests” have made such a global impression. Cannabis reform, in other words, is an easy fix for a country now thinking about the impact of popular revolutions of other kinds. Not to mention with a history of them. And even more particularly where reform last year allowed “le weed light” (low THC, high CBD strains) to go on sale (with a popular response).

Implications

How fast reform will move here is still obviously uncertain. The current government has been making noise about it for the last two years. Last year, the CBD market was allowed a little room to flourish in the new grey laws around reform (although even here, the first CBD “coffee shops” were shut down last summer almost as soon as they opened).

Given the conservative pace so far, look for France to follow rather than lead. From a CBD perspective, if not a THC one, the country looks very much more like Italy and Germany than Spain or Holland from the cannabis perspective – at least at present.

For such reasons, expect France to follow toute le monde, rather than lead the pack. Decriminalization plus some kind of insurance coverage (similar to Germany) is much more likely to be on the short-term agenda than say a massive rush to embrace the industry (as in Greece). The green revolution may now be in the wings here, but pushed by other unavoidable forces in Europe if not domestically.

That said, to paraphrase the words of the country’s last King, Louis VIX, when France does move on something resembling real reform, it will mean that after that, the “green deluge” will most certainly be on the hoof across the rest of the continent.

Blockchain Controversies Continue To Rock The Cannabis Industry

By Marguerite Arnold

2 Comments

Disclaimer: Marguerite Arnold is the founder of MedPayRx, a blockchained ecosystem that does not use utility tokens, and that is currently going to pilot in Europe designed to eliminate such risks.

As reported here in Cannabis Industry Journal last year in a three part series, there are considerable dangers of utilizing blockchain in the cannabis industry (as well as other industry sectors) that directly affect all commercial operators as well as consumers of both the recreational and medical kind. These remain largely unsolved.

These include regulatory and compliance issues in every direction, starting with banking and securities law, but also include privacy and consumer protections. They also fly in the face of regulations imposed by governments to control inflation, set prices for medications and food, and prevent monopolies.

Beyond that, they also pose considerable if so far unexamined liabilities for businesses operating in this space (including uncontrollable volatility in basic business operations) that very much impact the basic cost of doing business.As of the beginning of this year, however, the situation is back in the news.

The Skinny On Paragon
As of November last year, the company was sanctioned by the SEC in a precedent setting case on the issue of whether “utility tokens” are securities or not. In fact, the SEC found that Paragon illegally marketed and distributed digital securities under the false pretension that they were not securities. Paragon, in turn, reached a settlement with the SEC that it would return any funds received by investors prior to October 15, 2017 and pay a fine to the SEC.

As of the beginning of this year, however, the situation is back in the news. Because of the settlement agreement, it appears that a pump and dump group operating through the exchange YoBit managed to raise the token briefly from about $.10 a token to $10 in an effort to raise the cost of compensation from Paragon. This absurd rally was completely unsustainable, and as a result, fell back to $0.3 per token (albeit tripled the price of the token). But the fact that it happened at all is illustrative of the extreme risk now faced by the industry itself from this kind of tech and financial model.

Why? It means that all users (token holders) of such an ecosystem and for any purpose, would be directly exposed to such risks in the future. And on literally an hour-by-hour basis.

Utility tokens in other words, as defined by all such models (and Paragon is far from the only one), are used not only for investment in such businesses, but then bought downstream, via exchanges, by people who wish to transact in the network itself. And that is the real danger to businesses themselves by adopting such models.

Problem 1 – Utility Tokens Are Securities

The biggest issue at the heart of this conversation is this: Tokens are recognized now as securities, and further still operating in a world where pump and dump on the exchanges is a major liability for all who buy the tokens for any purpose. This means for example, that anyone who must buy a system cybercoin to transact within a blockchained ecosystem (from consumer to business manager overseeing international distribution of their product from the commercial end) would face unprecedented volatility that does not exist by using regulated currencies. Good old dollars and euros for example do not pose this kind of existential risk to businesses themselves.

In the Paragon case directly, for example, owning Paragon crypto means that monthly rent at the incubator would fluctuate in cost based on the unregulated cost of the coin, not a prenegotiated rental agreement in regular currency for space (which is far less volatile). In the current environment, such space just tripled in price.

Beyond that, no consumer in California, for example, would want to have to face the added cost of buying a hyped token (at artificially raised prices) before they can access the newest, coolest strain of bud.

Such systems in other words, are NOT just a fancy form of a digital payment solution (like Paypal). What they do dramatically increases the risk of price volatility in all business operations (also called “cost of goods sold” or COG), andto the end user while also directly exposing all to such risk at every point of production, processing and sales.

Why?Latency issues are also a major issue.

Because the cost of conducting normal, basic business operations would be directly exposed to speculating investors. Even local businesses, in other words, would be completely vulnerable to not just the fluctuations domestically or even internationally caused by doing business in multiple jurisdictions and traditional currency risk, but have direct and unprecedented exposure to a much less regulated and far more volatile price environment globally. And further one that affects literally the entire manufacturing and distribution process.

Problem 2 – Network Congestion

Latency issues are also a major issue. This is a bit more technical and complicated, but is one of the bigger reasons why most blockchain technology and solutions are still incapable of dealing with commercial industry requirements. Much less keep regulated industries in any space, in compliance.

Here is one way to think of the problem. If you have many users on a blockchain network all at once, speed of transaction goes way down and associated costs go way up.

The tokenized asset in other words, has to compete not only with people buying the token as an investment, but those using them to buy goods and services on the commercial side AND the industry processing taking place behind the scenes to fulfil and track product. This has been easy to see with Bitcoin in particular, but is not limited to the same.

Further, prioritization on a network itself (and the costs involved to overcome them, also paid in tokens) then unfairly creates a monopoly environment because of the added costs involved to speed up otherwise normally processed and critical operations. The biggest boys on the block(chain) win. Always. That is antithetical to anti-trust law.

Problem 4 – Undermining Basic Government Regulations On Cost Of Purchase

Here is the biggest conundrum, particularly facing the international cannabis industry now in the process of exporting across international borders. Governments (particularly in Europe) routinely set prices on medicine (in particular), for large contractual purchases and to insure the continued survival of public healthcare (which in Europe and the UK covers most people). See the German cultivation bid for cannabis as a prime example. The government is forcing the industry to submit prices via competitive bid that are expected to come in somewhere between 1-1.5 euro per gram. This in turn will affect not only domestically grown but imported cannabis – and from all points on the globe as the industry opens up.

That process is impossible in an environment where the cost of production itself would be (in a price volatile blockchained delivery system) inherently unpredictable and unstable because the price of production and distribution is itself a speculated upon commodity that can vary, literally, at the speed of a pump and dumped token, sold on any unregulated exchange, anywhere in the world. And as a result, is also illegal.

Sequoia Analytical Labs Caught Falsifying Results

By Aaron G. Biros

No Comments

Last month, Sequoia Analytical Labs admitted that they falsified hundreds of pesticide tests for batches of cannabis products. The Sacramento-based laboratory faked data on 22 different pesticide tests for more than 700 batches over a period of four months.

According to a notice posted on Sequoia’s website, the skewed results were originally found due to a “faulty instrument” but “it was further discovered” that the lab director knew about it and was fraudulently posting the results in order to hand out certificates of analysis. The lab director in question has since been fired and Sequoia voluntarily relinquished their state license.

Joe Devlin, Sacramento’s chief of cannabis enforcement, told KCRA3 News “We’re going to be taking a look at suspending or possibly revoking their permit.” He followed that up with saying that California needs more testing labs. “The shortage of labs has really created a bottleneck in the supply chain across the state,” says Devlin. There are only 43 licensed laboratories in the state of California as of this time, and just three of those are in Sacramento.

The Bureau of Cannabis Control (BCC), the regulatory authority overseeing the cannabis testing market in California, has not commented on this story, but they did reach out to distributors who had sent batches to Sequoia for testing. “Any cannabis goods from these batches, returned by consumers to the retailer, must be destroyed,” reads the BCC letter. “Any cannabis goods returned from a retailer’s inventory or remaining in your inventory may be destroyed, or may be re-sampled and re-tested after obtaining approval from the Bureau. Any cannabis goods from these batches may not be released to a retailer without re-sampling and re-testing.”

Sequoia Analytical Labs posted two notices on their homepage, one was a letter to their clients informing them of the fraud and the other is that BCC letter to distributors doing the same. “Management and ownership were horrified to learn about this severe breach of a very important safety regulation,” reads the notice. “We have voluntarily surrendered our license to do COA testing to the BCC while we make the required corrections. We are already hard at work making the needed changes to the instrument and revamping procedures so that we may get our license reinstated January 1.”

As of today, the lab’s license has not been reinstated.
