According to a press release published earlier this week, the Massachusetts Cannabis Control Commission approved Cannabis Trainers as one of the state’s first vendor training providers. The training program, Sell-SMaRT™ is the world’s first state-approved cannabis vendor training.
Regulations in Massachusetts require all licensed growers, managers and employees that handle cannabis to take a responsible vendor training class through a certified provider by January 1, 2020.
The Sell-SMaRT™ program was originally developed for licensees handling cannabis in Colorado. In 2015, Colorado regulators granted the program the first ever certification for its Responsible Vendor Program in cannabis. Since then, almost 4,000 people have taken the Cannabis Trainers class, which has been customized for six states, including Massachusetts.
Maureen McNamara, founder of Cannabis Trainers
Maureen McNamara, founder of Cannabis Trainers, built on two decades of experience in alcohol vendor training before she started the training program for cannabis. “Massachusetts is really setting a new standard with its training requirements,” says McNamara. “We’ve worked hard to customize the Sell-SMaRT™ program for the state’s needs, and we appreciate the Cannabis Control Commission’s recognition of that. We’re excited to help inspire a cannabis workforce in the state that is responsible, compliant and committed to excellence.”
Meg Sanders, CEO of Canna Provisions, a Massachusetts cannabis company, says the program helps her employees learn the rules thoroughly. “Cannabis Trainers trained all of my Colorado employees, and my entire team in Massachusetts as well,” says Sanders. “I know every time Cannabis Trainers meets with my staff, we walk away smarter and better prepared to help our customers.”
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.
Since medical cannabis was legalized in Ohio in 2016, companies that cultivate and process medical cannabis, as well as the plants themselves, have been popping up around the state.
Grow Ohio, a dual-licensed Level 1 cultivator and processor, was the first licensed processor in Ohio and the first to successfully bring product to market. From plant material to edibles, tinctures, oils, lotions and capsules, the company seeks to ensure that medical cannabis is cultivated and processed under the same strict standards as any pharmaceutical medication. As first to market, Grow Ohio found themselves navigating a complicated process by themselves.
As their first product was ready to be packaged, Executive Vice President (EVP) Justin Hunt and the team at Grow Ohio were focused on marketing, packaging and distributing their product. With the sheer number of items that required attention, it is easy to see how something like labelling can slip under the radar. With a variety of products and dosages, and the first delivery of the product slated for late April of 2019, Grow Ohio needed a consistent way to ensure their product complied with state law, and also satisfied their own brand standards.
As their April product launch date grew closer, Grow Ohio realized they needed help with executing on Ohio’s labeling requirements for medical cannabis products.
They turned to Adaptive Data Inc., a barcode and labeling systems supplier to provide labels, printers, and software. ADI’s task was to specify the right label materials for their branding and compliance needs and provide software and equipment to print compliance labels on demand. ADI’s proposed solution would slash the waste associated with printing and applying labels and create a lean process.
Compliance
Compliance labels must contain specific information and must be prominently visible and clearly legible. Containers have to be labeled with details including the specific quantity of product, dosage, THC levels, license #, testing lab name and ID #, and other details. Different sizes and shapes are required for the various packaging form factors.
Due to the large amount of content and a relatively small label area, ADI specified 300 dpi printer resolution so that 4 or 5 point fonts would be legible.
Hunt had all the information needed to comply with state regulations, but didn’t have a way to get that information, properly formatted, onto a finished label at the point of packaging. “It’s all about how you get the data from one source to the other in a way that is easily repeatable,” says Hunt. The solution provides the capability to handle all compliance requirements, for all types of product and all sizes/shapes of labels. The system is designed to minimize key entry of data, a typical source of content errors. All of Grow Ohio’s products contain THC and require the red THC compliance logo. Early on this requirement was met using a separate, hand-applied THC logo label, which was very costly. The labels now include the THC logo, all required compliance data, and the capability to include a 2d barcode.
At the time the products are packaged all compliance information is printed on demand with label printers. As retail expansion continues, the barcode on the plant material compliance label can be used with the POS systems of the dispensaries, to keep their systems fast and accurate.
Until the system is ready to receive data automatically from METRC, the State approved inventory system which tracks all medical cannabis plants and products grown or produced in Ohio, they used user interfaces that reduce the amount of data that is key entered to an absolute minimum. Using drop down lists, date pickers and calculated results, means that Grow Ohio only enters data in 5-10 fields, depending on product line. As the system evolves the next step will be to take data for compliance details automatically from METRC.
Branding
As the first to enter the medical marijuana market, Grow Ohio leadership knew that their brand image is as important to their success as the quality of their products. Their logo, color choice, and inclusion of the THC logo had to be consistent in appearance across all products, regardless of production method. They used full color branded product labels and blank labels that have the Grow Ohio and THC logo pre-printed. (Compliance data is added to the blank labels on demand.)
Label Application – Automatic, Semi-automatic and Manual
Grow Ohio packages in metal cans, glass bottles and in boxes. Each packaging type has specific requirements.
Metal Cans: Grow Ohio uses an automated packaging line for plant material in cans. That line includes two automatic apply-only machines (for brand labels). The compliance label is printed and dispensed and placed on the can as it is boxed.
Bottles: Cylindrical containers can be difficult to label. Grow Ohio originally packaged tinctures and oils in glass bottles which were pre-printed with their logo. The printed logo looked nice, but printing on the glass was expensive. This made placing the compliance label on the bottle more difficult, since the logo could not be covered. Positioning and straightness was critical for readability as well as aesthetics. Manual placement was time consuming (15 – 30 seconds per bottle).
Now, bottles are being processed with the help of a semi-automatic print-apply machine. The print-apply machine can label 18-20 bottles per minute.
By using plain bottles and pre-printing the blue Grow Ohio logo and red THC logo on the label, they were able to streamline the process. The semi-automatic print-apply machine adds the compliance data to the label and applies the label to the bottle.
The result is a lower total cost of the product. Plain bottles cost less without the logo and the labor to manually apply the labels has been greatly reduced. In addition, with the logos on the label instead of the bottle, orientation and spacing are no longer an issue. The label maintains the natural brand feel, which was important to Hunt.
Boxes: Only compliance labels are required for boxes as the branding information is pre-printed on the box. Compliance labels for boxes include a pre-printed, red THC logo. The printer prints the compliance data and presents the label with the liner removed, ready to be manually applied to the box.
Summary
With a broad product line, Grow Ohio’s label requirements are quite diverse. By specifying and sourcing the right hardware, software and label materials,
Adaptative Data provided an efficient, repeatable, cost-effective way to do brand and compliance labeling for Grow Ohio’s diverse product offering.
Hunt now understands the magnitude of work that goes into coming up with a compliant, cost-friendly compliance labeling approach – an appreciation he did not have at the outset. He is not alone in this regard as many companies come to this understanding late in the start-up process.
Hunt isn’t sure how fast the market will grow, but he is not worried. As the market expands and demand grows, he knows his systems can handle it.
Encore Labs is a full-service cannabis testing lab in Pasadena, California, providing all testing needs required by California’s Bureau of Cannabis Control (BCC). The BCC requires that cannabis products being sold in licensed dispensaries be tested for cannabinoid potency, heavy metals, microbial impurities, moisture content and water activity, mycotoxins, residual pesticides, residual solvents and processing chemicals, foreign materials and terpenes. It is Encore Labs’ goal to guarantee the quality and potency of all cannabis products while ensuring regulatory guidelines are met in the state of California.
Encore Labs provides quick turnaround times on a consistent basis. They take pride in offering excellent customer service without diminishing the quality of the work that they do. Their team of laboratory analysts/technicians are passionate about the industry and will never compromise their integrity just to make an extra buck.
Co-Founder, Spencer Wong, mentions their personal connection with clients. “Our customers don’t just see us as their testing laboratory, they see Encore Labs as their laboratory partner,” says Wong. “Besides performing analytical testing, we have worked with many customers to help formulate new products and do root cause analysis to pinpoint inefficiencies in their manufacturing operations and cultivation farms.”
ISO/IEC 17025 Accreditation has been extremely valuable to Encore Labs, especially regarding the new cannabis testing industry. “Our experience with Perry Johnson Laboratory Accreditation, Inc. has been great and has allowed for a very smooth and straightforward initial accreditation process. Their staff has been knowledgeable and responsive every step of the way,” says Wong.
Accreditation establishes that steps are being taken regarding quality and that laboratories are meeting and exceeding the highest testing standards. It also provides further assurance and confidence in data results as well as validated methods, staff training procedures, equipment calibration and successful participation in proficiency testing/interlaboratory comparisons.
Starting out with 1500 square feet of laboratory space, within the last year Encore Labs has doubled its work area. In order to meet the growing demand of the cannabis testing industry, they have added plans to once again double in size by the end of 2019, as well as open a second laboratory by the end of 2020.
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.
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?
On Tuesday, October 1, the National Cannabis Industry Association (NCIA) announced the release of their whitepaper, which provides guidance to the federal government on how cannabis could be regulated at the federal level. “The paper highlights the need to have a clearly defined regulatory approach and structure prepared as the nation moves closer to making cannabis legal for adults, and identifies the existing agencies best suited to regulate the wide variety of cannabis products available in state-regulated legal cannabis markets,” according to a press release.
The whitepaper was released on October 1. On October 2, Andrew Kline, director of public policy at NCIA, delivered the keynote presentation at the Cannabis Quality Conference in Illinois. His keynote delved into a number of issues related to the progress that cannabis legalization has made on Capitol Hill.
Andrew Kline, at the Cannabis Quality Conference, discussing the NCIA white paper.
Importantly, Kline also discussed the white paper and its four-lane approach to regulating cannabis at the federal level. “We believe rescheduling is bad public policy,” Kline mentioned during his keynote. Their stance is that cannabis should be rescheduled and regulated in a couple of different approaches. “We believe cannabis should be a public health issue and the FDA and the Department of Treasury should regulate cannabis much like they do alcohol.” Kline went into great depth later in the talk, discussing the four-lane plan for regulation, a state of affairs for cannabis bills in Congress and how members of the cannabis industry can get involved. “Right now, there is an unsustainable federalism clash, with cannabis as an illegal schedule I narcotic, while 33 states have legalized it, which leaves a lot of confusion in the marketplace and little protections for consumers; and we need to fix it.”
Lane 1 refers to pharmaceutical drugs, such as Epidiolex, where cannabis drugs can go through the new drug approval process, giving the FDA ultimate regulatory authority in this area. Lane 2 applies to ingested, inhaled or topically applied products with THC. This generally applies to all products containing THC. This lane gives regulatory authority to the Alcohol, Tobacco, Tax and Trade Bureau (TTB), essentially regulating cannabis like alcohol or cigarettes. Lane 3 is for ingested and inhaled products with less than 0.3% THC. These would be regulated like dietary supplements and food ingredients, giving the FDA regulatory oversight here as well. Lane 4 applies only to topical products with less than 0.3% THC, regulating them much like the FDA does with cosmetic products.
The above summary is not thorough or detailed. We highly encourage our readers to read the full whitepaper to understand how cannabis could be regulated at the federal level and how the NCIA thinks the government should do so.
“As a country, we are starting to move past whether we should end cannabis prohibition, and need to put serious consideration into how we do that and what a post-legalization world looks like in terms of federal regulatory policy,” says Aaron Smith, executive director at NCIA, in a press release. “The recommendations outlined in this report build on successful methodologies by assigning regulatory duties to existing agencies, while avoiding restrictions that would not be appropriate for cannabis as well as some of the missteps that have occurred with other products. We look forward to working with Congress to overturn our outdated federal marijuana laws and begin implementing this structure to help ensure public safety and displace the illicit cannabis market.”

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.
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.
There 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.
