The Best Way to Remediate Moldy Cannabis is No Remediation at All

By Ingo Mueller
3 Comments

Consumers are largely unaware that most commercial cannabis grown today undergoes some form of decontamination to treat the industry’s growing problem of mold, yeast and other microbial pathogens. As more cannabis brands fail regulatory testing for contaminants, businesses are increasingly turning to radiation, ozone gas, hydrogen peroxide or other damaging remediation methods to ensure compliance and avoid product recalls. It has made cannabis cultivation and extraction more challenging and more expensive than ever, not to mention inflaming the industry’s ongoing supply problem.

The problem is only going to get worse as states like Nevada and California are beginning to implement more regulations including even tougher microbial contamination limits. The technological and economic burdens are becoming too much for some cultivators, driving some of them out of business. It’s also putting an even greater strain on them to meet product demand.

It’s critical that the industry establishes new product standards to reassure consumers that the cannabis products they buy are safe. But it is even more critical that the industry look beyond traditional agricultural remediation methods to solve the microbial problems.

Compounding Risks

Mold and other microbial pathogens are found everywhere in the environment, including the air, food and water that people consume. While there is no consensus yet on the health consequences of consuming these contaminants through cannabis, risks are certainly emerging. According to a 2015 study by the Cannabis Safety Institutei, molds are generally harmless in the environment, but some may present a health threat when inhaled, particularly to immunocompromised individuals. Mycotoxins resulting from molds such as Aspergillus can cause illnesses such as allergic bronchopulmonary aspergillosis. Even when killed with treatment, the dead pathogens could trigger allergies or asthma.

There is an abundance of pathogens that can affect cannabis cultivation, but the most common types are Botrytis (bud rot, sometimes called gray mold) and Powdery Mildew. They are also among the most devastating blights to cannabis crops. Numerous chemical controls are available to help prevent or stem an outbreak, ranging from fungicides and horticultural oils to bicarbonates and biological controls. While these controls may save an otherwise doomed crop, they introduce their own potential health risks through the overexposure and consumption of chemical residues.

The issue is further compounded by the fact that the states in which cannabis is legal can’t agree on which microbial pathogens to test for, nor how to test. Colorado, for instance, requires only three pathogen tests (for salmonella, E. coli, and mycotoxins from mold), while Massachusetts has exceedingly strict testing regulations for clean products. Massachusetts-based testing lab, ProVerde Laboratories, reports that approximately 30% of the cannabis flowers it tests have some kind of mold or yeast contamination.

If a cannabis product fails required microbial testing and can’t be remedied in a compliant way, the grower will inevitably experience a severe – and potentially crippling – financial hit to a lost crop. Willow Industries, a microbial remediation company, says that cannabis microbial contamination is projected to be a $3 billion problem by 2020ii.

Remediation Falls Short
With the financial stakes so high, the cannabis industry has taken cues from the food industry and adopted a variety of ways to remediate cannabis harvests contaminated with pathogens. Ketch DeGabrielle of Qloris Consulting spent two years studying cannabis microbial remediation methods and summarized their pros and consiii.

He found that some common sterilization approaches like autoclaves, steam and dry heat are impractical for cannabis due the decarboxylation and harsh damage they inflict on the product. Some growers spray or immerse cannabis flowers in hydrogen peroxide, but the resulting moisture can actually cause more spores to germinate, while the chemical reduces the terpene content in the flowers.

Powdery mildew starts with white/grey spots seen on the upper leaves surface

The more favored, technologically advanced remediation approaches include ozone or similar gas treatment, which is relatively inexpensive and treats the entire plant. However, it’s difficult to gas products on a large scale, and gas results in terpene loss. Microwaves can kill pathogens effectively through cellular rupture, but can burn the product. Ionizing radiation kills microbial life by destroying their DNA, but the process can create carcinogenic chemical compounds and harmful free radicals. Radio frequency (which DeGabrielle considers the best method) effectively kills yeast and mold by oscillating the water in them, but it can result in moisture and terpene loss.

The bottom line: no remediation method is perfect. Prevention of microbial contamination is a better approach. But all three conventional approaches to cannabis cultivation – outdoors, greenhouses and indoor grow operations – make it extremely difficult to control contamination. Mold spores can easily gain a foothold both indoors and out through air, water, food and human contact, quickly spreading into an epidemic.

The industry needs to establish new quality standards for product purity and employ new growing practices to meet them. Advanced technologies can help create near perfect growing ecosystems and microclimates for growing cannabis free of mold contamination. Internet of Things sensors combined with AI-driven robotics and automation can dramatically reduce human intervention in the growing process, along with human-induced contamination. Natural sunlight supplemented with new lighting technologies that provide near full-light and UV spectrum can stimulate robust growth more resistant to disease. Computational fluid dynamic models can help growers achieve optimal temperature, humidity, velocity, filtration and sanitation of air flow. And tissue culture micropropagation of plant stock can eliminate virus and pathogen threats, to name just a few of the latest innovations.

Growing legal cannabis today is a risky business that can cost growers millions of dollars if pathogens contaminate a crop. Remediation methods to remove microbial contamination may work to varying degrees, but they introduce another set of problems that can impact consumer health and comprise product quality.

A Regulatory Tsunami is Washing Over the Canadian Cannabis Industry

By Steven Burton
No Comments
Steven Burton

On August 29, 2019, Health Canada finally published a guidance document on the official interpretation of Part 5 of the Cannabis Regulations concerning “Good Production Practices” that comes into force just seven weeks later on October 17, 2019. For those watching with the experience of the food industry, it is safe to say that few license holders fully appreciate the magnitude of the new requirements and fewer yet are prepared for what will be required in less than two weeks.

An Uncertain Road to Cannabis Compliance

Since Canada legalized recreational cannabis in October 2018, there has been considerable uncertainty about the road to compliance in this totally new legal market. Health Canada faced the daunting challenge of defining the requirements for a whole new industry, and so they were understandably silent on the issue of Part 5 until this guide was published in August.

GMPMany larger companies eager to get their foot in the door of the multi-billion dollar industry tried to be proactive in anticipating impending government regulations by seeking Good Manufacturing Practices (GMP) certifications. This would likely have been fine under the previous regulations, which were myopically focused on ensuring that product wasn’t diverted from or to the black market. With the legalization of edibles only one year away, however, it was obvious to those in the food industry that GMP was just not going to be enough. Gentle prodding at various speaking engagements on our part wasn’t enough to convince these companies to seek higher levels of certification or at least to proactively develop the organizational culture required to support a higher-level program.

The Inevitable Necessity of Food Safety

It was clear to us that since edibles are essentially a food product, safety necessarily had to become a primary focus. This reality has, in fact, materialized in section 5 of the new guide, which outlines prescriptive requirements that are very well developed and require that companies develop a complete set of Standard Operating Procedures (SOPs) for sanitation, employee hygiene, testing, inventory, pest control and more. Furthermore, cannabis companies must be able to produce documentation that proves they are actually following these procedures.

There are many, many other requirements that also apply, but the really interesting ones are those related to hazard analysis (5.2.13) and preventive control plans (5.2.14): manufacturers who produce extracts or edibles must undertake hazard analyses on each input, processing step and traffic flow. The language will be familiar to those who have been exposed to Hazard Analysis and Critical Control Point (HACCP) methodology. HACCP is the standard in the food industry and goes far beyond simple GMP.

Very much like HACCP, license holders will be required to analyze each biological, chemical and physical hazard, determine controls, identify critical control point, along will all the validation, reassessment, verification and deviation protocols required. Interestingly, the fraud and bioterrorism hazard types that have recently been introduced for the food industry have been omitted, presumably an oversight that will be rectified in future versions.

How to Catch Up Fast with Tech

Satisfying these regulations using traditional manual methods takes months or even years in some cases. Today in Canada, license holders have only weeks to get their facilities to compliance, and the government is quick to crack down on any mistakes. The only way to possibly meet this deadline is to start yesterday and use the best tools you can find to expedite the process.

HACCPThose who have been busy implementing GMP programs are going to have to look far beyond their current objectives. Those just starting out should build with these requirements front of mind, both to satisfy inspectors and auditors and also to avoid the pain of the organizational change required to move to a higher level of quality and safety.

Ultimately, these changes will be of benefit to society and provide a competitive advantage to those who can move the fastest, especially when major retail chains become the dominant wholesale market. My advice is to start working on your HACCP-based compliance program immediately and, if you’re in Canada, seek a high-level certification like SQF as soon as possible.

It’s fair to say that the food industry’s recent experiences with more stringent regulations clearly foreshadow what will be required for the cannabis industry. Right now – when the margin of error is razor thin – is the time for companies to make the decisive move and focus on their success – and survival.

Navigating Cannabis Staffing and Hiring Challenges

By Michael Coleman

With more cannabis staffing and recruiting challenges than ever before, building a healthy pipeline of top candidates can be an uphill battle. From a lack of qualified candidates and working capital to the haze of lingering stigma and industry volatility, cannabis hiring and retention challenges are more apparent than ever.

Understanding the pain points of cannabis staffing and how to flip them in your favor is critical for attracting the talent you need to grow your business.

Emerging Candidate Concerns

Low unemployment coupled with high demand for qualified talent has led to fierce competition among cannabis hiring managers and HR professionals. This means finding candidates with the right skills and industry experience can be exceptionally difficult.

Dispensary and budtender jobs are some of the most popular entry-level cannabis employment opportunities. But since these are customer-facing roles, the requirements to work in a dispensary span a range of skillsets.

Not only do candidates need excellent interpersonal skills, they should also have a deep understanding of the differences and synergies in strains, terpene profiles and cannabinoid contents. The starting hourly pay for these retail dispensary jobs is only about $12-16 per hour. Finding candidates with relevant dispensary experience at such a low rate is not an easy feat.

Then there are the extractors and directors of extraction. While these positions are higher-paying than dispensary jobs, they are more dangerous and require a more specific skillset. Engaging qualified candidates for this high-risk position can take a lot of time and effort. In addition, employers also have to assume liabilities and higher compensation demands.

Other cannabis employment types that staffing departments and agencies have to hire are highly specialized.

Not only do you need talented and knowledgeable salespeople, marketers and accountants, there are also laboratory workers, trimmers, cultivation laborers and supervisors, master growers, dispensary managers and delivery drivers to account for.

Lack of Working Capital

With market demand continuing to rise, having the manpower in place is vital to remain competitive. But hiring costs money. Recruiting, advertising and interviewing requires adequate cannabis funding and/or working capital. Unfortunately, obtaining and securing capital to grow and hire is difficult in the industry today.

Making the wrong hiring decision can be costly. If you break any laws during the recruiting process, you can get hit with a hefty lawsuit. The majority of industry players today are startups with limited financial resources. A lawsuit can mean shutting down shop and going out of business.

The Volatile Nature of the Industry

The advancement and adoption of cannabis legislation are rapidly underway for medical use, recreational use and everything in between.

With shifting public sentiments, state-specific cannabis laws and licensing requirements, the industry is in a constant state of change. Even the requirements to work in the cannabis industry vary from state to state.

The ever-rising tide of volatility makes it difficult for companies to find enough stability to make responsible hiring decisions. One regulatory revision can require a company to pivot its branding, product line and entire marketing strategy from top to bottom. A shift in strategy can mean a shift in employee requirements and skillsets. This instability tends to be unappealing to candidates who are accustomed to a well-established workplace structure and culture.

With so much volatility and uncertainty, prioritizing employee relationship management seems like a wise decision. But in-house cannabis human resources is just not in the cards in many cases. Instead, cannabis staffing, recruiting and HR tend to be outsourced along with accounting and compliance.

Lack of Suitable Cannabis Recruiting Platforms

While perceptions are changing, misconceptions about the industry are still pervasive.

Lingering market stigma presents a grave challenge for cannabis staffing and hiring. In fact, many mainstream recruiting platforms are unwilling to partner with cannabis companies. Fortunately, there are some relatively new cannabis HR agencies and platforms to help solve some of the challenges of hiring in cannabis. Vangst GIGS, for example, is the first and only fully-compliant cannabis staffing platform. The CBD staffing agency has been up and running for just a few years now.

Future of Cannabis Staffing and Hiring Demands

While hemp-derived CBD has been legal since the signing of the 2018 U.S. Farm Bill, marijuana-derived CBD is still illegal. But this may change sooner rather than later.

There is growing bipartisan support for the legalization and regulation of cannabis. Beyond improving quality assurance and resolving the disconnect between state and federal laws, federal cannabis legalization will have a profound impact on the U.S. economy.

In fact, New Frontier Data projects federal legalization will create $128.8 billion in additional tax revenue and 1.63 million legal cannabis jobs in the U.S. by 2025.

Cannabis payroll deductions could also increase to $9.5 billion by 2025 because more legal entities, customers and employees would be participating in the market.

With federal legislation likely coming in the near future, knowing how to navigate and scale cannabis human resources, including hemp staffing, are more important than ever. You need the right people and processes to take advantage of the market opportunities legalization would create.

Companies that adapt to industry changes will be better at recruiting top talent and mitigating future staffing shortages. Forward-looking companies and fund managers are already obtaining cannabis business loans and ramping up HR preparations and organizational structuring to get a jumpstart on the pace of change.

CBD In The UK: An Unregulated Marketplace

By Marguerite Arnold

You have to give it to this industry. Everyone wants in. And well, Prohibition is so over.

The problem is, particularly here in Europe, for the most part, this is either the tedious process of educating doctors, creating medical grade product that insurers will pay for, or of course, trials to look forward to in the immediate future.

In other words, decidedly less colorful (or at least in the North American sense) if not at lower volume than other places.

In the meantime, particularly filtered via American and Canadian coverage and industry success stories, the British are succumbing to the green magic any way they can.

The structure of cannabidiol (CBD), one of 400 active compounds found in cannabis.

Low-THC, CBD products as a result, are flourishing in a way that seems a bit like the “Colorado of Europe.” The early days. When all sorts of strange stories about processing leaked out of the first legalizing state market in the U.S. It is shocking to European eyes, in particular, of late.

“CBD” is, literally, everywhere.

For those with other kinds of experience in the world of cannabis, however, it is both slightly sad and slightly exhilarating. The Brits have the cannabis bug. But they seem a bit lost on where to go next.

What Is The Deal In The UK?

Regulations are weird here. You cannot use the flower of any cannabis flower (including those with under the requisite amount of THC) – also known as hemp. The novel food discussion is lost.

Regardless, there are clearly plans afoot, particularly on the corporate farming level, to begin a transformation of crops to include cannabis sometime soon. And far beyond the farmers, the boys in the city are getting hot under the collar for this kind of green.

London is also turning into (rather predictably) a center of all things cannabis equity.

There are already more specialty funds planning to list on London exchanges than anywhere else in Europe.

But is this all that surprising?

In the midst of Brexit, a failing NHS, and a society at odds with itself like no time since the 1970’s, the British are facing the cannabis revolution with anything but a stiff upper lip.

When it comes to all things cannabinoids, at least on the CBD side, no matter the odd police raid on a health food store or crunchy vegan experiment on land not protected by the rights of an inherited “country pile”, the cannabis horse, certainly of the broadly stroked CBD variety, is out of the barn.

But What Does this Really Mean?

For the moment? As globally financed companies set up in the UK for all kinds of cannabis trials, the CBD market here is taking on an oddly Bulldog twist.

There is more of a cottage industry of all kinds of CBD products unseen elsewhere in Europe (including from the U.S.). Labeling, testing and sourcing are largely a matter of hit or miss. And just like everywhere else, desperate, sick, depressed people (or those who fear becoming that way) are turning to the CBD miracle to fix a range of conditions.

The problem is that a lot of this is pure snake oil.

Yes, high quality, medical grade CBD does work as a stabilizer (just like THC). But not every oil containing some measure of highly diluted (or worse, contaminated) cannabinoid extract, is the panacea that cannabis offers.

Bottom line? The CBD market in the UK is sort of like Swiss Lite. There are medical trials in the offing, but the country is also in the middle of a constitutional crisis. There are many regulations, and of a bit more fundamentally intrinsic kind, on the line right now. Cannabis is in the room. But so is the Irish Border (the largest if not most existential sticking point in the never-ending Brexit negotiations).

Investing In The UK CBD Market

There are investors who are clearly examining the market, and a few big deals so far, but the vast majority of money flowing into the UK is going into its more flexible (if not frothy) equity market. The British, in other words, may be flailing a bit on domestic implementation, but equity funds in London are in touch with global investors on this issue – even if that money then flows back into Europe.

How very British.

GMP

What Does GMP Mean? And How Is This Different From EU-GMP?

By Marguerite Arnold

GMP

The cannabis industry is on the road to legitimacy, no matter the bumps, globally. No matter what, and no matter what happens next, that is a good thing. Issues like supply chain transparency, privacy, consumer and patient safety, and of course energy and water use have long been in the room just about everywhere.

Cleantech Is Cannatech

The modern cannabis industry was birthed and given significant shape in deserts (Israel, California, Nevada). In California, as of 2014, producers were warned, yet again, that they could not avail themselves of federally overseen aquifers of groundwater. The legitimizing industry trucked in what it needed.

On the medical discussion, in Europe, in particular, such issues are now in the room. All medical cannabis must be grown indoors. No exceptions.

That means low energy, high efficiency production is on the rise, not the wane.

What Does GMP Mean?

The overall regulations and operating procedures that surround this discussion are known as “Good Manufacturing Practices,” or GMPs for short. But like all the best acronyms, what the standards are, who sets them, and where they are equivalent is still a shifting picture.

Further, GMPs, and even more particularly EU-GMPs, are specifically referred to this way to distinguish the medically bound product from other consumer protection regulations that include novel food.

european union statesThat said, “GMP practices” differ widely from industry to industry. The idea behind them, however is to prevent harm from occurring to the user, including that the end product is free from contamination, and the packaging as well as manufacture has been well documented. Additional requirements include that personnel are properly trained.

And while the practice, at the pointed end of enforcement can get nerdy, detail-oriented and specific, that is precisely the point. That is also why you might catch another variant of this acronym (cGMP – or current GMP guidelines), to denote a world that is changing fast.

Contamination of the supply chain if not the carbon impact of the same, for all food and plant-based pharmaceutical products is a 21st century problem that is exploding on the scene as fast as the planet warms and cannabis legalizes.

What Do GMP Guidelines Include?

These are guidelines, not steps. As a result, from a bird’s eye view, all international and sovereign national GMP standards include a few basic principles no matter how much they may differ in the weeds. Namely:

  • That manufacturing processes are clean, controlled and processes are verifiable and repeatable. Changes to any and all must also be clearly documented.
  • Record keeping, accurate accounting (of product and on the financial side) must be kept, including complete batch history through manufacture and distribution to the end user. Audits are a way of life.
  • Recall procedures must be in effect.
  • All complaints about products must be examined.

The World Health Organization (WHO) version of GMP is what’s used by pharmaceutical regulators worldwide. The European Union’s EU-GMP standards are seen as roughly equivalent, as are those now practiced in the U.S. by the FDA. That does not mean that confusion does not reign as standards are changing (across Europe, for example, between individual countries, there is still disagreement). However similar GMPs are used in countries including Australia, Canada, Japan, and Singapore. The UK, of course, is slightly different than anyone else but still has regulations that are roughly equivalent and referred to as “The Orange Guide” (in honor of the color of the book’s cover).

You Know It When You See It

Well, not quite. Beyond GMP, there are of course, other classifications for the kind of plant or product being made, manufactured and distributed. And here, along with international treaties about who can trade with whom, also impact this discussion.

It is not correct, however, for example, to claim that what are known as GACP guidelines (good agricultural and collection practices) are equivalent to GMP. Bio, or pesticide free production (in other words) is just one of many steps in meeting much higher standards now in the room for medically bound cannabis.

What Is GMP “Like”?

All industries have “best practices.” For example, the building industry has all sorts of codes and guidelines. However, in addition to this, about a decade ago, LEED (or green building) certification began to be implemented widely. In the U.S., in particular, there was much discussion about how honest such certifications actually were. The term “greenwashing” was frequently used to describe practices that were sold as energy efficient, but in the end cost more, environmentally and otherwise, than they should.

Like LEED, GMP is not a prescribed set of steps but rather best practice guidelines and regulations meant to guide industries on producing safe products – from seed to sale.

How Does This Differ From WHO Guidelines on GACP for Medicinal Plants?

The World Health Organization’s GACP guidelines are highly controversial in this context, especially when it comes to cannabis. Especially because they refer specifically to plants used as medicine that are “grown in the wild.” I.e. not greenhouse. How these guidelines are interpreted by different countries, however, within the context of the interpretation of “medical cannabis” not to mention pharmaceutical GMPs, are very different.

GACP guidelines, in other words, are sometimes the first step in qualification – but certification under the same (starting with outdoor grown crops produced without pesticides for example) is not likely to pass European medical standards any time soon.

Cannabis Featured At Germany’s ExpoPharm For The First Time

By Marguerite Arnold
1 Comment

Expopharm is a big deal in Germany and Europe beyond that. It is the largest expo for pharmacists on the continent.

This year, there were two firsts in a convention already looking to the future with digitalization – itself a huge issue in not only the European medical space, but Germany in particular. There is a national obsession with privacy auf Deutschland that does not exist anywhere else.

Beyond digitalization, however, medical cannabis was also a major theme this year. Many of the largest producers and distributors showed up in force. So did the smaller, newer ones. There are now 19 licensed importers in the country – and quite a few of them showed up in Dusseldorf last week.

Beyond that, the expo also saw the birth of the VCA – the Verband der Cannabis versorgende Apotheken e.V (German Cannabis Pharmacists Association). This is a group of pharmacists who are on the front lines of the medical cannabis revolution on its most complicated, expensive and paper-laden end, determined to make their voices heard.

the VCA ,German Cannabis Pharmacists Association

According to Tobias Loder, the owner of Luxe 99 Apotheke in Cologne and one of the organizers of the VCA, “There is huge interest in our association.”

For those of American extraction, at least, there has yet to be such a conference anywhere in the U.S. simply because of the lack of acceptance at the federal level of cannabis as medicine. In Canada, and elsewhere, national pharmacy chains are already getting into the action.

Germany, however, remains the strange, and as a result, most interesting exception.

In Düsseldorf this year, despite added traffic and a great deal of excitement, cannabis as medicine was, as the press attendant said as he handed out the Cannabis Industry Journal press pass, “par for the course” and “no big deal.” Even though of course, the generation of all the interest and intrigue.

The drug is, while still highly stigmatized, on its way to legitimacy here. And in a decidedly normal, Deutsch weg (way).

The Inside Skinny On What Is Changing For German Pharmacists

As revealed during the Denton’s medical cannabis conference in Berlin in late September (about a day before the news hit the expo floor in fact), things are indeed changing at the last mile of the regulated cannabis path. Why?

Several reasons.

Within the next thirty days, doctors will be able to prescribe up to 100 grams of floss (dried cannabis flower) or cannabis oil by the gram per patient prescription. That means that patients can indeed go to the doctor every three months – and that there are in fact more regular users in the system. This is also an indication that the supply chain is also beginning to normalize – although there is a huge demand so far unmet by supply. And as a result, while two of the three bid winners are now getting down to cultivation, imports are still the name of the game.

On this front, things are also changing. Cannabis just came into the country from Portugal. Other countries lining up to import include not only Canadian producers, but those from Spain, Malta, Greece, Australia, South Africa, Columbia and of course, Israel.

This is also a step towards international normalization on the pharma side. Schedule II narcotics in the American system are dispensed every 90 days.

The rules about pharmacy mark-ups are also in flux. One of the reasons, for example, that medical cannabis has been so expensive is that, up until now, at least, pharmacists were required to mark up such product 100%. That is also changing. In fact, the Federal Union of German Associations of Pharmacists (ABDA) and the National Association of Statutory Health Insurance Funds (GKV Spitzenenverand) have had to agree on a new surcharge that is expected to see significant and immediate savings of a projected 25 million euros.

It is not a casual argument or discussion. One of the reasons that the German pharmacy vertical has remained so strong and resistant to buyouts and consolidations is that by law, owners are limited to no more than three (and in so far one case discovered by CIJ in Bavaria) four brick and mortar pharmacies. The reduction in this preparation surcharge means that pharmacies will have to find ways to become more efficient. That is also a concern for the VCA, who, among other things, are looking to reduce their own overhead costs while gearing up to serve more patients.

Digitalization, innovation and more, in other words, is on the table. And German pharmacists, for one, are not only on the front line – but stepping up to the challenge.

CannTrust Faces Alberta Product Return

By Marguerite Arnold
3 Comments

The negativity keeps on coming for the embattled CannTrust. As of late September, the Alberta Gaming, Liquor and Cannabis Commission (AGLC) decided to return $1.3 million of the company’s products – or almost all inventory already ordered by the commission.

The AGLC operates independently of Health Canada, and the regulator has not ordered a recall of any of CannTrust’s products even though they suspended the company’s license. However, the AGLC has a contractual relationship with the company, which allows it to return company products on CannTrust’s expense.

The Ontario government has already announced that it would be returning about $2.9 million in products to CannTrust.

In The Regulatory Weed(s)

Why are so many recreational market Canadian authorities doing the same thing that Danish authorities initiated July 9, when the news about CannTrust hit Europe?

Beyond all the illegal growing, there are other problems that have now come to light that essentially invalidate if not put into question the legitimacy of CannTrust’s entire grow operation – and for both the medical and recreational market.

As Bloomberg first reported, CannTrust employees brought black market seeds into their unlicensed growing rooms at the facility in Pelham Ontario and even relabelled them to look like brands they were supposed to be carrying. It is unknown how many of these plants were actually sold, but over 1,000 plants were grown and flowered by CannTrust with murky origins. If that is not enough to make Canadian authorities go nuts, it certainly has stirred waves of anger in Europe where seed control is a huge issue, far beyond the medical market. See Novel Food and the huge angst of the developing CBD market.

It is hard to understand exactly, in retrospect, therefore, what CannTrust executives, or even employees thought they were doing exactly.

One thing, however is for sure. CannTrust is not “just” the meltdown of one company in Canada. The entire industry, globally, is paying attention. Particularly those in parts of the world now looking at the opening map of cannabis ex-im.

A Brave New World On The High Seas

As Peter Homberg, one of the top global legal experts at Denton’s law firm pointed out in September in Berlin during a high-level medical cannabis conference, the world is indeed changing fast on the cannabis ex-im front. Producers from Malta, Greece, Denmark, Spain, Portugal and Australia as well as latest market entrant Columbia right now are lining up to import into Germany if not Europe beyond that.

why did this company deliberately go so astray?This is a world governed by several international treaties, national law and regional tolerance.

It is complicated. But in Europe at least, while in the throws of now finding some standard equivalency tests, there is a universal standard – namely good manufacturing practices – to adhere to that is “international” even if just within the EU and for those firms interested in entering the market here.

That is one of the reasons that the Canadian government is in the hot seat to prove to the world that internal regs are up to snuff.

What Impact Will This Have On The U.S?

As CannTrust was not importing across the U.S.-Canadian border, there is no product recall to be had. However, other issues, including investor lawsuits, loom.

On top of this, the regulatory issues faced by the Canadian government in a fully recreational market are, of course, not invisible to those just “south of the border.” Notably, California. Of any state in the union right now, the state is the most advanced on the cannabis regulations front – even if more complicated and nuanced than in any other U.S. state jurisdiction. Of course, they still have generations of unlicensed grower networks to contend with.

None of this was ever going to be easy.

The question in the room, however, post-CannTrust, certainly, is that given the opportunity to go on the straight and narrow, why did this company deliberately go so astray?

Analytical Instruments You Need to Start a Cannabis Testing Laboratory

By Bob Clifford
8 Comments

The cannabis industry is growing exponentially, and the use of cannabis for medical purposes is being adopted across the nation. With this boom in cannabis consumers, there has been an increasing need for knowledge about the product.

The role of testing labs has become crucial to the process, which makes owning and operating a lab more lucrative. Scientists testing for potency, heavy metals, pesticides, residual solvents, moisture, terpene profile, microbial and fungal growth, and mycotoxins/aflatoxins are able to make meaningful contributions to the medical industry by making sure products are safe, while simultaneously generating profits and a return on investment.

Here are the key testing instruments you need to conduct these critical analyses. Note that cannabis analytical testing requirements may vary by state, so be sure to check the regulations applicable to the location of your laboratory.

Potency Testing

High-performance liquid chromatograph (HPLC) designed for quantitative determination of cannabinoid content.

The most important component of cannabis testing is the analysis of cannabinoid profiles, also known as potency. Cannabis plants naturally produce cannabinoids that determine the overall effect and strength of the cultivar, which is also referred to as the strain. There are many different cannabinoids that all have distinct medicinal effects. However, most states only require testing and reporting for the dry weight percentages of delta-9-tetrahydrocannabinol (Δ9-THC) and cannabidiol (CBD). It should be noted that delta-9-tetrahydrocannabinolic acid (Δ9-THCA) can be converted to THC through oxidation with heat or light.

For potency testing, traditional high-performance liquid chromatography (HPLC) is recommended and has become the gold standard for analyzing cannabinoid profiles. Look for a turnkey HPLC analyzer that delivers a comprehensive package that integrates instrument hardware, software, consumables and proven HPLC methods.

Heavy Metal Testing

ICP-MS instrument for detecting heavy metals in cannabis.

Different types of metals can be found in soils and fertilizers, and as cannabis plants grow, they tend to draw in these metals from the soil. Heavy metals are a group of metals considered to be toxic, and the most common include lead, cadmium, arsenic and mercury. Most labs are required to test and confirm that samples are under the allowable toxic concentration limits for these four hazardous metals.

Heavy metal testing is performed by inductively coupled plasma mass spectrometry (ICP-MS). ICP-MS uses the different masses of each element to determine which elements are present within a sample and at what concentrations. Make sure to include accompanying software that provides assistant functions to simplify analysis by developing analytical methods and automatically diagnosing spectral interference. This will provide easy operation and analytical results with exceptionally high reliability.

To reduce running costs, look for a supporting hardware system that reduces the consumption of argon gas and electricity. For example, use a plasma ignition sequence that is optimized for lower-purity argon gas (i.e., 99.9% argon as opposed to more expensive 99.9999%).

Pesticide Testing

The detection of pesticides in cannabis can be a challenge. There are many pesticides that are used in commercial cannabis grow operations to kill the pests that thrive on the plants and in greenhouses. These chemicals are toxic to humans, so confirming their absence from cannabis products is crucial. The number of pesticides that must be tested for varies from state to state, with Colorado requiring only 13 pesticides, whereas Oregon and California require 59 and 66 respectively. Canada has taken it a step further and must test for 96 pesticides, while AOAC International is developing methods for testing for 104 pesticides. The list of pesticides will continue to evolve as the industry evolves.

Testing for pesticides is one of the more problematic analyses, possibly resulting in the need for two different instruments depending on the state’s requirements. For a majority of pesticides, liquid chromatography mass spectrometry (LCMS) is acceptable and operates much like HPLC but utilizes a different detector and sample preparation.

With excellent sensitivity and ultra-low detection limits, LC-MS/MS is an ideal technique for the analysis of pesticides.

Pesticides that do not ionize well in an LCMS source require the use of a gas chromatography mass spectrometry (GCMS) instrument. The principles of HPLC still apply – you inject a sample, separate it on a column and detect with a detector. However, in this case, a gas (typically helium) is used to carry the sample.

Look for a LC-MS/MS system or HPLC system with a triple quadrupole mass spectrometer that provides ultra-low detection limits, high sensitivity and efficient throughput. Advanced systems can analyze more than 200 pesticides in 12 minutes.

For GCMS analysis, consider an instrument that utilizes a triple quadrupole mass spectrometer to help maximize the capabilities of your laboratory. Select an instrument that is designed with enhanced functionality, analysis software, databases and a sample introduction system. Also include a headspace autosampler, which can also be used for terpene profiles and residual solvent testing.

Residual Solvent Testing

Residual solvents are chemicals left over from the process of extracting cannabinoids and terpenes from the cannabis plant. Common solvents for such extractions include ethanol, butane, propane and hexane. These solvents are evaporated to prepare high-concentration oils and waxes. However, it is sometimes necessary to use large quantities of solvent in order to increase extraction efficiency and to achieve higher levels of purity. Since these solvents are not safe for human consumption, most states require labs to verify that all traces of the substances have been removed.

Testing for residual solvents requires gas chromatography (GC). For this process, a small amount of extract is put into a vial and heated to mimic the natural evaporation process. The amount of solvent that is evaporated from the sample and into the air is referred to as the “headspace.” The headspace is then extracted with a syringe and placed in the injection port of the GC. This technique is called full-evaporated technique (FET) and utilizes the headspace autosampler for the GC.

Look for a GCMS instrument with a headspace autosampler, which can also be used for pesticide and terpene analysis.

Terpene Profile Testing

Terpenes are produced in the trichomes of the cannabis leaves, where THC is created, and are common constituents of the plant’s distinctive flavor and aroma. Terpenes also act as essential medicinal hydrocarbon building blocks, influencing the overall homeopathic and therapeutic effect of the product. The characterization of terpenes and their synergistic effect with cannabinoids are key for identifying the correct cannabis treatment plan for patients with pain, anxiety, epilepsy, depression, cancer and other illnesses. This test is not required by most states, but it is recommended.

The instrumentation that is used for analyzing terpene profiles is a GCMS with headspace autosampler with an appropriate spectral library. Since residual solvent testing is an analysis required by most states, all of the instrumentation required for terpene profiling will already be in your lab.

As with residual solvent testing, look for a GCMS instrument with a headspace autosampler (see above). 

Microbe, Fungus and Mycotoxin Testing

Most states mandate that cannabis testing labs analyze samples for any fungal or microbial growth resulting from production or handling, as well as for mycotoxins, which are toxins produced by fungi. With the potential to become lethal, continuous exposure to mycotoxins can lead to a buildup of progressively worse allergic reactions.

LCMS should be used to qualify and identify strains of mycotoxins. However, determining the amount of microorganisms present is another challenge. That testing can be done using enzyme linked immunosorbent assay (ELISA), quantitative polymerase chain reaction (qPCR) or matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS), with each having their advantages and disadvantages.

For mycotoxin analysis, select a high-sensitivity LC-MS/MS instrument. In addition to standard LC, using an MS/MS selective detector enables labs to obtain limits of detection up to 1000 times greater than conventional LC-UV instruments.

For qPCR and its associated needs, look for a real-time PCR amplification system that combines thermal cyclers with optical reaction modules for singleplex and multiplex detection of fluorophores. These real-time PCR detection systems range from economical two-target detection to sophisticated five-target or more detection systems. The real-time detection platform should offer reliable gradient-enabled thermal cyclers for rapid assay optimization. Accompanying software built to work with the system simplifies plate setup, data collection, data analysis and data visualization of real-time PCR results.

Moisture Content and Water Activity Testing

Moisture content testing is required in some states. Moisture can be extremely detrimental to the quality of stored cannabis products. Dried cannabis typically has a moisture content of 5% to 12%. A moisture content above 12% in dried cannabis is prone to fungal growth (mold). As medical users may be immune deficient and vulnerable to the effects of mold, constant monitoring of moisture is needed. Below a 5% moisture content, the cannabis will turn to a dust-like texture.

The best way to analyze the moisture content of any product is using the thermogravimetric method with a moisture balance instrument. This process involves placing the sample of cannabis into the sample chamber and taking an initial reading. Then the moisture balance instrument heats up until all the moisture has been evaporated out of the sample. A final reading is then taken to determine the percent weight of moisture that was contained in the original sample.

A moisture balance can provide accurate determination of moisture content in cannabis.

Look for a moisture balance that offers intuitive operation and quick, accurate determination of moisture content. The pan should be spacious enough to allow large samples to be spread thinly. The halogen heater and reflector plate should combine to enable precise, uniform heating. Advanced features can include preset, modifiable measurement modes like automated ending, timed ending, rapid drying, slow drying and step drying.

Another method for preventing mold is monitoring water activity (aW). Very simply, moisture content is the total amount of water available, while water activity is the “free water” that could produce mold. Water activityranges from 0 to 1. Pure water would have an aW of 1.0. ASTM methods D8196-18 and D8297-18 are methods for monitoring water activity in dry cannabis flower. The aW range recommended for storage is 0.55 to 0.65. Some states recommend moisture content to be monitored, other states monitor water activity, and some states such as California recommend monitoring both.

Final Thoughts

As you can see, cannabis growers benefit tremendously from cannabis testing. Whether meeting state requirements or certifying a product, laboratory testing reduces growers’ risk and ensures delivery of a quality product. As medicinal and recreational cannabis markets continue to grow, analytical testing will ensure that consumers are receiving accurately

labeled products that are free from contamination. That’s why it is important to invest in the future of your cannabis testing lab by selecting the right analytical equipment at the start of your venture.

Polish Authorities Halt Medical Cannabis Product Registration

In early September, Polish authorities halted medical cannabis product registrations.

It is still unclear what this was caused by. However, in conversations with the Dutch Cannabis Agency, Cannabis Industry Journal learned the Dutch government ran into significant problems with Polish acceptance of documents in the February 2019 timeframe. Further, CIJ has also learned that several other Canadian companies had apparently been trying to target Bedrocan products in Poland with this knowledge.

Even before authorities halted the registration process, it is clear that the often cut-throat game-playing seen in Germany frequently over the last few years, has also clearly entered the room just a bit east.

Is Cannabis Really Coming to Poland?

There is a national election in late October in Poland. There is a great deal on the line.

Including, of course, not just the dreams of Polish entrepreneurial hopefuls, but all of the largest cannabis companies on the planet. Poland has been a strategic and often unheralded market for most of them over the last 18 months. Aurora in fact, even announced its first import into the country last fall when the government announced a loosening of restrictions. And as the last country to enter into the EU-US MRA Agreement, with a conservative approach to cannabis at least in government, the country is ostensibly a big blue ocean for all things canna reform.

However, since most of the big companies use Germany as their product breakpoint, the news of a product registration delay nationally means that companies already in the room with EU-recognized product just got a big break.

Even if it is only short selling as much as they can into the market until product registration finally occurs.

A new kind of German-Canadian canna blitzkrieg of Poland is about to get underway this fall – certainly of the cannabis kind, although anyone with already registered EU product (see Germany for starters) has a big competitive leg up.

Cannapolitics Are In Play Across Europe

If this is the temperature in the room already, look for more machinations over the apparently pending Polish bid – although perhaps by that point, reform will have progressed far enough in Europe to prevent the same kind of local market hijacking by those with a public company and a will to dominate the market.

That said, expect backlash too, now from frustrated advocacy patient groups tired of more government blather about widespread reform that is clearly not mapped to come their way any time soon.

Here is the inconvenient and certainly unsolved reality in the room that so far has remained unsolved.

european union statesThere is zero way that even the largest companies in the room can provide enough product, local producers are on the rise, and there is clearly a building “green-vest” kind of uprising in the burgeoning industry itself. EU local and national sovereign producers are getting into the game and in a big way.

The reality is that this plant provides relief to pain of several kinds – from patients to locally starved municipal and state budgets.

Recreational Is On The Longer Term Horizon – But Major Hurdles Remain

While the largest companies have clearly been in the room shaping reform policy and in ways that are not necessarily in the best interests of the overall industry itself, let alone patients, there is the real potential for backlash right now. Particularly in Europe which has heard all the wonder stories about the economics if not other impacts of cannabis reform.

Europeans – even in the industry here – who venture to American state markets in particular, but also Canadian outlets – are very much in envy. However, most also realize that the market here will evolve differently.

That is why there are now starting to be all kinds of trials on the map – and of the recreational and medical kind.

The culture is in the middle of a massive, cannabis shift. The early market entry created by the political and economic clout of the early movers was important.

But as the world turns ever more green, local politics, and even more importantly, sovereign cannabis production and even export is increasingly a political issue in the room.
