Blockchain Controversies Continue To Rock The Cannabis Industry

By Marguerite Arnold

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


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

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

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

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

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

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

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

Problem 1 – Utility Tokens Are Securities

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

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

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

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

Why?Latency issues are also a major issue.

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

Problem 2 – Network Congestion

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

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

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

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

Problem 4 – Undermining Basic Government Regulations On Cost Of Purchase

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

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

Sequoia Analytical Labs Caught Falsifying Results

By Aaron G. Biros

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

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

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

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

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

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

Israel and Thailand Approve Cannabis Exports

By Marguerite Arnold

israel flag

On Christmas Day, not only did Israel, global leader in medical cannabis in particular, finally decide to legalize medical exports, but in a surprise move, so did Thailand.

Both developments are likely to have huge implications on the entire global cannabis discussion, albeit in slightly different ways.The impact will be interesting to watch.

Israel’s Export Decision

The issue of exports from the original home of the medical cannabinoid revolution has been a perennial sticky wicket for the last several years. As the Israeli medical market liberalized at home and certainly in the last five years, the government steadfastly refused to export the drug. Further, the country’s president Benjamin Netanyahu also cut a political deal with Donald Trump to move the Israeli capital from Tel Aviv to Jerusalem that delayed this discussion over the last 18 months. With a global market now exploding that Israel to date has been excluded from and Netanyahu’s political capital tarnished with corruption, things are about to change.

The impact will be interesting to watch. Especially with the network of Israeli production farms also sprinkling around particularly Eastern Europe and Greece.

Thai Surprise

Thailand’s parliament voted to legalize the use of medical cannabis, making it the first country in Southeast Asia to do so.

Here is also what is intriguing: The country is, like Israel, looking at creating a domestic boon with a tightly controlled domestic economy booster. Not to mention clearing the jails, which are filled to bursting with people on even low level drug offenses.

Thailand’s Parliament

And just like Israel, Thailand is also, already, talking protectionist measures to shield domestic producers from being bought out by foreign interests, certainly of the corporate kind.

The Combination Package

In the short term this means, at least on the export front, that there will be more competitors to the Canadian giants now entering the room. And between Israel and Thailand alone, this also means that new strains on the medical side, will begin to enter global medical markets.

For all the future promise of tweaked product, cheap cannabis flower and oil flooding markets globally by importers and distributors realizing that the game is far from over, is going to be the first real challenge the Canadian cannabis companies have yet faced.

In the wake of the news that Epidiolex is not as effective longer term as hoped (which is a common phenomenon in the pharmaceutical industry known as a “drug holiday” where users initially improve and then develop tolerance to the drug), this is also an intriguing new development. This means that new strains are entering the global market at an unprecedented pace, literally competing with pharmaceutical products at a time when reform continues apace.

At a time when cannabis investments (particularly in the US), quadrupled in 2018, this also means that western dollars, if not companies, will begin to find other markets and market outlets.

And that is a Christmas present in 2018 that will reverberate long into the future.

Digipath Labs Now ISO 17025:2017 Accredited

By Aaron G. Biros
No Comments

According to a press release published in December, Digipath Labs, based in Las Vegas, Nevada, was recently accredited to the updated ISO standard, ISO 17025:2017. The laboratory received their accreditation from Perry Johnson Laboratory Accreditation (PJLA).

ISO 17025:2005 has long been the standard that labs seek accreditation to, but their newest 2017 edition was recently rolled out and introduced to the market. The new 2017 standard includes some broad changes to terminology, process approach, scope, and it importantly introduces the concept of risk-based thinking.

That concept of risk-based thinking is particularly relevant to the cannabis testing market, where many have argued for more transparency and uniformity in different state regulations and markets. Introducing risk-based thinking in the standard means that assessors also look at the risk of bias, impartiality and assessing measurement uncertainty, which certainly adds a layer of subjectivity to the accreditation.

PJLATracy Szerszen, president/operations manager of PJLA, says the newer standard also includes a provision for a quality management system review among other changes. “We are making sure they are following the standard from a technical standpoint, meaning they have the right equipment, the appropriate personnel and also have a quality management system,” says Szerszen. “November 29, 2020 is the deadline for moving to the new 2017 standard.”

According to Todd Denkin, CEO and founder of Digipath, obtaining the new ISO accreditation poises them for future growth and expansion. “Digipath Labs has now brought its standard of excellence in cannabis testing under the updated ISO-17025:2017 umbrella as we seek to expand our dominance in cannabis testing markets,” says Denkin. “This is a major step in positioning Digipath as a global leader in testing services.”

This Bud’s For You: Tilray Enters The Drinkable Cannabis Market

By Marguerite Arnold

The race is on for drinkable cannabinoids. In mid-December, Tilray announced a $100 million joint venture with Anheuser Busch to research and develop infused non-alcoholic drinks for the Canadian market.

This is the second big beer company to partner with a cannabis industry leader (see Canopy Growth’s partnership with Constellation Brands), who has just invested another $4 billion in the company.

Molson Coors also announced a deal with Hexo in August. On the non-alcoholic side of the ledger, Coca-Cola and Aurora have also had talks, reportedly eyeing the cannabis market.

Short term in other words, a lot of drinkable cannabis is coming to a market near you.tilray-logo

Why Is Drinkable Cannabis So Intriguing?

Cannabinoids themselves, are not water soluble. However, when cannabinoids are subjected to a process called nano emulsion, (emulsified oil, water and molecules), they can be not only added to drinks but potentially represent one of the most cutting edge forms of drug, vitamin, mineral and overall nutrition delivery. Nanoemulsions are approximately the size of viruses, proteins and antibodies with a transparent or semi-translucent appearance. They also tend to increase bioavailability of substances.

In other words, while the focus on the market as it is developing in Canada is “recreational” and “beverage” use, in fact, this technology can be applied to food. It will also be used, obviously on the medical side of the equation too.

Nanotechnology overall is actually a manufacturing technology that works with atoms to change the structure of matter. When it comes to edibles of all kinds (food, drinks and medications) nutrients are absorbed more uniformly and pass through to membranes directly into human cells.

The impact of that technology, mixed with a revolutionary drug, is no longer theoretical.One of the best known uses of nanotechnology in the world is also one of the most common condiments. Mayonnaise for example, is an emulsion of tiny particles where oil and water are mixed together without separating. That said, these days researchers are developing techniques that allow these tiny droplets to be precisely tailored to give them specific tastes and textures.

The technology, in other words, that the cannabis and major drinks manufacturers are now developing, will allow cannabinoids to be used in food, drinks and medications in ways that go far beyond pills and oils.

This is not your grandparent’s beverage, food, drug or alcohol market in other words. This represents another way for the cannabis industry to lead the way on a range of products far from “canna-beer.” Or even THC-infused social lubricants.

The impact of that technology, mixed with a revolutionary drug, is no longer theoretical.

The Cellular Revolution of Cannabinoids Is Now Here

If allowed to efficiently access cells via nanotechnology, no matter how it is consumed, the idea of a cannabis infused food or drink might well become enough not only to “keep the doctor away” but in general revolutionize concepts of nutrition, not to mention medication.

That said, there are still many questions in general that remain about the safety of this kind of technology within the human body. Nanoceuticals can help bypass typical protective barriers of the body and deliver bio-chemicals that the body would not normally encounter. There has not been a lot of study (yet) on their biodegradability or metabolism of nanotechnologies. Namely the human body may not be able to expel them. They are currently unregulated and can be introduced to the market with little or no evidence of safety or efficacy although this is also on the way. There are concerns that this delivery method could literally disrupt DNA.

Cannabinoids themselves appear to be a systemic biological regulator. But the active ingredients used to emulsify the plant may or may not be.

In an industry in other words, which has systematically been ahead of regulatory approval, starting with legalization itself, the future looks not only highly intriguing, but full of major debates about with what and how human beings are nourished, and treated medically.

As usual, in other words, the cannabis industry, is pioneering a truly brave new world.

Farm Bill Analysis: Is Hemp Legal Now?

By Aaron G. Biros
No Comments

On December 20, President Trump signed the Agriculture Improvement Act of 2018 (the Farm Bill) into law, which included an important change to the way federal agencies regulate hemp farming and production. The Farm Bill essentially removes hemp-derived cannabidiol (CBD) from the Controlled Substances Act in states that choose to regulate it. It strips the Drug Enforcement Agency’s (DEA’s) authority from outlawing hemp and gives states the ability to regulate hemp markets on their own, with approval from the United States Department of Agriculture (USDA).

This gives the USDA the authority to regulate hemp farming, providing for things like access to banks, insurance, grants, certifications and gets rid of the need for a pilot program, which was previously the case under the 2014 Farm Bill. It also defines hemp a little better, to include cannabinoids, derivatives and extracts.

According to Aaron Smith, executive director of the National Cannabis Industry Association (NCIA), the signing of the Farm Bill is a crucial step towards full legalization. “The lifting of the federal ban on non-psychoactive hemp is a concrete sign that the ‘reefer madness’ which first led to its criminalization is finally coming to an end,” says Smith. “This Farm Bill is a step in the right direction for comprehensive cannabis policy reform and will help fuel discussions in Congress about the best ways to end federal prohibition and create a regulated national cannabis market.”

FDAlogoHowever, one particularly important caveat needs to be mentioned: The Food and Drug Administration (FDA) still retains regulatory authority over CBD products. In a statement released the same day that the Farm Bill was signed, the FDA addressed their oversight capabilities. “We’ll take enforcement action needed to protect public health against companies illegally selling cannabis and cannabis-derived products that can put consumers at risk and are being marketed in violation of the FDA’s authorities,” reads the FDA statement. “The FDA has sent warning letters in the past to companies illegally selling CBD products that claimed to prevent, diagnose, treat, or cure serious diseases, such as cancer. Some of these products were in further violation of the FD&C Act [Federal Food, Drug and Cosmetics Act] because they were marketed as dietary supplements or because they involved the addition of CBD to food.”

The Farm Bill signing opened the doors for hemp cultivation and production in the United States.What the FDA said in their statement is crucial information for those developing hemp-derived products. They recommend that companies use traditional pathways to get approval from the FDA to market their products, providing the Epidiolex example where the drug manufacturer used clinical studies to prove the drug’s efficacy.

The FDA also notes that there are circumstances “in which certain cannabis-derived compounds might be permitted in a food or dietary supplement.” That means they are exploring opportunities for companies to develop, manufacture and market legal CBD products without going through the extensive drug approval process.States need to establish programs approved by the USDA and companies need to cooperate with the FDA, taking the necessary steps to get their products and marketing approved.

In the food ingredients realm, they have already taken steps to approve hulled hemp seeds, hemp seed protein and hemp seed oil as generally recognized as safe (GRAS). “Therefore, these products can be legally marketed in human foods for these uses without food additive approval, provided they comply with all other requirements and do not make disease treatment claims,” reads the FDA statement.

The Farm Bill signing opened the doors for hemp cultivation and production in the United States. It allows farmers to access the same goods and services extended to other commodities farming, it makes conducting business easier across state lines, it will pave the way for more research into hemp as an effective medicine and helps to end the debate over hemp’s legality. But this doesn’t mean any business can just start producing and selling CBD products. States need to establish programs approved by the USDA and companies need to cooperate with the FDA, taking the necessary steps to get their products and marketing approved.

In the coming months and years, we will see which states decide to develop hemp cultivation programs and how the proliferation of hemp-derived products will evolve under FDA regulatory oversight.

Deibel Cannabis Laboratories Launches Cannabis-Specific HACCP Program

By Dr. Laurie Post
No Comments

Manufacturers of cannabis products need a program tailored to the cannabis industry that helps assure the safety of cannabis products with respect to known hazards such as pesticides, residual solvents, microbial impurities, heavy metals and mycotoxins. Deibel Cannabis Laboratories has developed a course that that will teach those manufacturing cannabis products how to manage known product safety hazards using a Hazard Analysis and Critical Control Point (HACCP) system.

HACCP has a long history of use in the food industry based on preventing potential hazards from occurring rather than reacting to issues when they arise. This program was started in the US but is globally recognized, used by food companies around the world to help produce safe products for consumers. Deibel Cannabis Laboratories applies the same prevention based system of HACCP to the creation of safe and wholesome cannabis goods whether they be edible, medicinal or topical. They also explore ways cultivators can use HACCP principles in their operation.12

Deibel Labs was founded by Dr. Robert Deibel in the 1970’s. Dr. Deibel is one of the original pioneers of HACCP, expanding the program from its original three HACCP principles to the seven principles we recognize today. Dr. Deibel developed the first “HACCP Short Course,” teaching this prevention-based program to food industry leaders in the 1970s.

According to Charles Deibel, president of Deibel Labs, this is an important step for the cannabis space. “Deibel Labs is proud to continue in our historic role as leaders in HACCP training by providing the cannabis industry with a training course developed by Deibel Labs associates who are International HACCP Alliance accredited lead instructors with years of experience in crafting and implementing HACCP plans for the food industry.”

They are launching a pilot two-day Cannabis HACCP Class to select clients at the end of January in Santa Cruz, CA. The full Cannabis HACCP course schedule for 2019 is currently in development. Accreditation by the HACCP Alliance is expected by early January, assuring that a standardized and internationally recognized training curriculum is provided by accredited instructors.

The course is forward-thinking, anticipating that sometime in the near future cannabis manufacturers will be required to control and document the safe production, handling and preparation of products according to state or even federal regulatory standards. Participants will be able to develop their own model HACCP program in an interactive group learning environment.

Attendees will:

  • Understand how Prerequisite Programs provide the foundation on which HACCP programs are built including GMPs, Sanitation and Pest Control Programs
  • Be able to identify where and how product safety problems can occur using a Hazard Analysis that considers Biological, Chemical and Physical Hazards
  • Gain the skills, knowledge, and tools necessary to develop effective Critical Controls, formulate corrective actions, conduct program verification and validation activities
  • Learn how to document activities and maintain records

Stay tuned for more information on when the 2019 course schedule is announced and how to register.

5 Compliance Reporting and Notification Requirements That You May Not Know About

By Anne Conn
1 Comment

New cannabis businesses must demonstrate proof of compliance to myriad laws and regulations as part of the initial license application process. And once a license is issued, it is easy to prioritize day-to-day business operations over ongoing compliance reporting requirements especially when sales are booming and compliance requirements are multi-layered, vague or obscured in non-cannabis specific programs and regulations.

But seemingly benign neglect of some minor reporting requirements can have major consequences to new and established businesses alike.

This article explores five compliance reporting requirements that cannabis businesses may not know about, and suggests ways to maintain a strong compliance posture across all regulatory agencies.

Pesticide Reporting

All licensed growers are required to prove compliance to state pesticide usage regulations. However, expectations on how and when to provide that proof of compliance vary greatly from state to state.  Furthermore, the responsibility of education and enforcement for pesticide usage in the cannabis industry often falls to non-cannabis specific agencies such as state departments of agriculture or environmental compliance.

For example in California, cultivators must report detailed monthly pesticide use reports via the State’s Agriculture Weights/Measures Division reporting portal, while Washington State regulators simply expect cultivators to keep records locally on site and provide them when requested.

With so many places to look, the best place to start your pesticide reporting requirement search is with your local agriculture department. They should be able to answer your questions and provide you with a list of resources to help you better understand how to comply with state pesticide usage and reporting regulations.

Hazardous Materials Reporting

Like pesticide use and reporting, hazardous waste handling and reporting requirements are complex and vary state to state. In fact, there may even be nuanced variations in handling requirements at the county level. The best approach to ensure compliance with a complicated set of regulations is to start by consulting your local county fire department. They will have the most specific set of rules for hazardous materials handling and reporting and can help you develop a site-specific compliance plan.

Two OSHA reporting requirements

Depending on how your cannabis business is classified, you may be required to keep injury and illness incident records and provide reports to the Occupational Health and Safety Organization (OSHA) for specific time periods.

Contact your business insurance provider’s loss prevention representative for more information about how your business is classified, which specific OSHA reporting requirements apply to you, and how to stay in compliance with applicable OSHA requirements.

Click here to learn more about how OSHA organizes reporting requirements by business type.

A note of caution here: OSHA non-compliance penalties can be steep and “I didn’t know I was supposed to do that” is not an acceptable defense when it comes to explaining any OSHA violations.

Labor Law Notification Requirements

Federal labor law requires that you notify employees of their rights. At a minimum, you post information regarding wages and hours, child labor, unemployment benefits, safety and health/workers’ compensation and discrimination in a conspicuous place where they are easily visible to all employees. Some states requires additional information be posted in a similar manner, so it’s important to be sure that those notices are posted along with the federal requirements.

This is a simple, yet easily overlooked, requirement for all businesses, regardless of industry. Ask your insurance provider for a copy of the notice to print and post right away (if you have not already) for a quick compliance win!

These five reporting and notification requirements may seem tedious, overly complicated and burdensome in the face of day-to-day business operations, but compliance to these requirements not only protects your business and employees, it also enhances the overall reputation of the industry. The good news is that regulatory agencies welcome a proactive approach and are happy to work with cannabis businesses to provide guidance and information for developing compliance plans.

Gas Chromatography/Infrared Spectroscopy: A Tool For the Analysis of Organic Compounds in Cannabis

IR Spectrum of 2,4-Dichlorophenol in different physical states

Editor’s Note: The author will be teaching a 1/2 day short course on this topic at PITTCON in Philadelphia in March 2019.


The combination of gas chromatography and infrared spectroscopy (GC/IR) is a powerful tool for the characterization of compounds in complex mixtures. (1-5) Gas chromatography with mass spectroscopy detection (GC/MS) is a similar technique, but GC/MS is a destructive technique that tears apart the sample molecules during the ionization process and then these fragments are used to characterize the molecule. In GC/IR the molecules are not destroyed but the IR light produced by molecular vibrations are used to characterize the molecule. IR spectrum yields information about the whole molecule which allows the characterization of specific isomers and functional groups. GC/IR is complementary to GC/MS and the combination results in a powerful tool for the analytical chemist.

A good example of the utility of GC/IR vs GC/MS is the characterization of stereo isomers. Stereo isomers are mirror images such as a left hand and a right hand. In nature, stereo isomers are very important as one isomers will be more active then its mirror image. Stereo isomers are critical to medicinal application of cannabis and also a factor in the flavor components of cannabis.

GC/MS is good at identifying basic structure, where GC/IR can identify subtle differences in structure. GC/MS could identify a hand, GC/IR could tell you if it is a left hand or right hand. GC/MS can identify a general class of compounds, GC/IR can identify the specific isomer present.

Why GC/IR?

Gas chromatography interfaced with infrared detection (GC/IR), combines the separation ability of GC and the structural information from IR spectroscopy. GC/IR gives the analyst the ability to obtain information complementary to GC/MS. GC/IR gives the analyst the power to perform functional group detection and differentiate between similar molecular isomers that is difficult with GC/MS. Isomer specificity can be very important in flavor and medical applications.

IR Spectrum of 2,4-Dichlorophenol in different physical states

Gas chromatography with mass spectrometry detection (GC/MS) is the state-of-the-art method for the identification of unknown compounds. GC/MS, however, is not infallible and many compounds are difficult to identify with 100 % certainty. The problem with GC/MS is that it is a destructive method that tears apart a molecule. In infrared spectrometry (IR), molecular identification is based upon the IR absorptions of the whole molecule. This technique allows differentiation among isomers and yields information about functional groups and the position of such groups in a molecule. GC/IR complements the information obtained by GC/MS.

Interfaces

Initial attempts to couple GC with IR were made using high capacity GC columns and stopped flow techniques. As GC columns and IR technology advanced, the GC/IR method became more applicable. The advent of fused silica capillary GC columns and the availability of Fourier transform infrared spectrometry made GC/IR available commercially in several forms. GC/IR using a flow cell to capture the IR spectrum in real time is known as the “Light Pipe”. This is the most common form of GC/IR and the easiest to use. GC/IR can also be done by capturing or “trapping” the analytes of interest eluting from a GC and then measuring the IR spectrum. This can be done by cryogenically trapping the analyte in the solid phase. A third possibility is to trap the analyte in a matrix of inert material causing “Matrix Isolation” of the analyte followed by measuring the IR spectrum.

Infrared Spectroscopy

The physical state of the sample has a large effect upon the IR spectrum produced. Molecular interactions (especially hydrogen bonding) broadens absorption peaks. Solid and liquid samples produce IR spectra with broadened peaks that loses much of the potential information obtained in the spectra. Surrounding the sample molecule with gas molecules or in an inert matrix greatly sharpens the peaks in the spectrum, revealing more of the information and producing a “cleaner” spectrum. These spectra lend themselves better to computer searches of spectral libraries similar to the computer searching done in mass spectroscopy. IR spectral computer searching requires the standard spectra in the library be of the same physical state as the sample. So, a spectrum taken in a gaseous state should be searched against a library of spectra of standards in the gaseous state.

IR of various phases:

  • Liquid Phase – Molecular interactions broaden absorption peaks.
  • Solid Phase – Molecular interactions broaden absorption peaks.
  • Gas Phase – Lack of molecular interactions sharpen absorption peaks.
  • Matrix Isolation – Lack of molecular interactions sharpen absorption peaks.

IR Chromatograms

GC/IR yields chromatograms of infrared absorbance over time. These can be total infrared absorbance which is similar to the total ion chromatogram (TIC) in GC/MS or the infrared absorbance over a narrow band or bands analogous to selected ion chromatogram. This is a very powerful ability, because it gives the user the ability to focus on selected functional groups in a mixture of compounds.

Conclusion

Gas chromatography with infrared detection is a powerful tool for the elucidation of the structure of organic compounds in a mixture. It is complementary to GC/MS and is used to identify specific isomers and congeners of organic compounds. This method is greatly needed in the Cannabis industry to monitor the compounds that determine the flavor and the medicinal value of its products.

Wayland Group Makes European Waves

While it is news that Wayland Group has just signed a definitive production agreement in Italy with a local CBD producer (Factory S.S. – a subsidiary of Group San Martino), it is not that Wayland has been establishing itself in Europe for the past two years.

Nor is it surprising that the new Italian plant (named CBD Italian Factory) will feature world-class cleantech production technology (fuelled by biogas). Even more intriguingly the joint venture also includes a relationship with the University of Eastern Piedmont, which is developing a research center to study the development of cannabinoid products for both animals and people.

Why not?Europe is far from the only region on Wayland’s global expansion map.

Wayland has been establishing itself in an interesting way as the company expands globally that distinguishes its corporate strategy from its other cannabis competitors. It was only April of this year, after all, that Wayland received its ex-im license to ship dried cannabis flower from Canada to Germany. At a time when the company also used to be known as Maricann. That corporate name change happened this year too, as the company continues to build its global brand in very interesting if far-flung markets.

A Busy Fall So Far

Europe is far from the only region on Wayland’s global expansion map. In the first week of November, in fact, the company also signed an agreement to buy 100% of Colma Pharmaceutical SAS, a Columbian-licensed producer of THC. This will be an outdoor THC play, and produce two crops a year. They also just announced a land acquisition in Argentina to begin cultivating cannabis there as well.

In October, the company announced not only plans to raise $50 million, but also brought on three new board members with significant European legal and business experience (including M&A and access to equity markets). This includes the company’s first female board member, Birgit Homburger, based in Berlin.

And this is on top of its record-breaking hemp harvest in Germany, which outperformed internal forecasts by a factor of 2. This is an important benchmark domestically, as German cultivation licenses will require successful firms to prove they can bring large quantities of flower to market successfully and repeatedly.

A Marked Interest In Cannatech

Like many firms, Wayland is already showing a marked interest in new cannabis technologies, in particular, innovative cultivation solutions, but not limited to the same. In August, the company unveiled its first product launch in Europe – a soft gel with 25mg of CBD that utilizes multi-patented technology allowing optimum absorption and bioavailability. Its German unveiling is significant because the insurance and medical industries here are unclear about dosing. That lack of clarity is also now holding back policy and underwriting issues, including the approval of medical cannabis in the first place.

These capsules, a non-medical product and marketed under the name “Mariplant” were first shipped to pharmacies in both the Munich and Cologne area in the late summer.It has continued to expand both its Canadian and foreign as well as tech expansions ever since.

The Road So Far

The company, which started with a facility in Langton, Canada in 2013, earned a license from Health Canada to sell cannabis extracts in early 2016. By December of that year (a good four months before the German cultivation bid was announced) Maricann GmbH was formed in Munich. By March, the month before the cultivation bid was first announced, the company began retrofitting the Ebersbach facility, near Dresden.

In April of 2017, Maricann went public. It has continued to expand both its Canadian and foreign as well as tech expansions ever since.

While not a “high flier” on the stock market (like competitors Tilray, Canopy and Aurora), the company is carefully plotting its position in a global market that is still very much a “blue ocean” opportunity.

It is also carefully plotting a path into both production and delivery systems that are optimized by tech in a universe that is rapidly upgrading not only its image, but finding ways to prove if not justify medical efficacy.
