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

By Daniel Erickson
1 Comment

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

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

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

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

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

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

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

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

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

French Cannabis Reform Is Finally In The Offing

By Marguerite Arnold
No Comments

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

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

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

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

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

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

Implications

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

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

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

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

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.

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.”

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.

Product Labeling Law: A Primer and a Warning for California Cannabis Executives

By Jonathan C. Sandler
No Comments

What do you get when you combine a Schedule 1 federally controlled substance with a plethora of food, beverage and cosmetic entrepreneurs marketing new products to inexperienced users and then place that combustible combination into California’s plaintiff-friendly legal environment?

A lot of rich plaintiffs’ attorneys.

California continues to be a favored plaintiffs’ lawyers’ venue for filing consumer-related lawsuits against food and cosmetic companies. These lawsuits result in tens of millions in settlements each year and hundreds of millions in judgments. Staying current on statutes and trends is critical to doing business in California and cannabis companies are no exception.

While the Food and Drug Administration (“FDA”) has provided very little guidance on how cannabis products should be labeled, a lack of specific regulations does not mean that there are no applicable labeling requirements for cannabis. This is particularly true in states like California that have a multitude of statutes designed to protect consumers from false or misleading advertising and labeling. Below includes a brief list to help guide companies’ labelling processes:

  1. Look to available guidance for the relevant industries. For example, food labeling of cannabis products still requires compliance with other nutritional labeling statutes. The same goes for supplements and cosmetics. The Fair Packaging and Label Act (“FPLA”) regulates labeling of all “consumer commodities” as to net contents, product identity, and manufacturer’s, packer’s or distributor’s name and location.
  2. Consider the intended use of the product as well as the directions. For example, is the product meant to be consumed all at once or should it be consumed over a period of time? Depending upon the product, this question can affect whether compliance with the FDA dietary supplements guidance is required or whether the Food Drug and Cosmetic Act applies.
  3. Consider your supply chains. This can be one of the most difficult aspects for cannabis companies that are looking to expand, but need more supply. However, keeping track of ingredients is a critical aspect to being able to defend against lawsuits. In the past, cannabis companies have been sued because they have expanded their suppliers without assuring consistency in the products and then combining inconsistent ingredients into one common product that is now mislabeled. While the Bureau of Cannabis Control testing requirements should help with some of the cannabis information, all ingredients need to be tracked and the final products tested.
  4. Cannabis companies must label their products with applicable state laws. For example, the California Safe Drinking Water and Toxic Enforcement Act of 1986, better known as Proposition 65 (“Prop. 65”)is being used by the plaintiffs’ bar as a basis to sue cannabis companies.
    • Prop. 65 is a statewide initiative that regulates companies that make or sell their products in California in two ways: (1) it requires companies whose products contain certain levels of chemicals to provide clear and reasonable warnings. Prop. 65 does not ban or restrict the sale of chemicals on the list or their inclusion in products, but it requires warnings if the listed chemicals are included; and (2) It prevents companies from discharging these chemicals into the state’s water supply.
    • All companies doing business in California and all products manufactured or sold in California are subject to Prop. 65 with three exceptions: (1) the company has fewer than 10 employees, (2) government agencies, or (3) the products contain less than a threshold amount of the chemicals.
    • Penalties for violations can be staggering. Prop. 65 is enforced both by the California Attorney General and private lawsuits on behalf of the California Attorney General. The potential penalties for violations of Prop. 65 include a fine of up to $2,500 per day. Additionally, one of the largest drivers of litigation is that the private enforcers (plaintiffs’ bar) can recover their attorneys’ fees. The total amount paid in settlements in 2017 was over $25 million and of the more than $18 million in judgments, $13 million was attributed to attorneys’ fees.
  5. The California Consumers Legal Remedies Act (“CLRA”) is another California statute that is intended to protect consumers from false advertising and other unfair business practices. The CLRA allows consumers to bring individual or California class action lawsuits to recover damages and enjoin the prohibited practices. The statute also allows a prevailing consumer to recover attorneys’ fees and costs. Cannabis companies need to be mindful of their representations related to their products. California courts are filled with cases involving terms like “natural” or “healthy” or “high performing.”

Product labeling, mottos and advertisements may seem straightforward, but they form the basis for hundreds of lawsuits filed every year throughout the country, and especially in California. At this stage of trying to get one’s product out the door and to the consumer, it is tempting to move quickly. However, the importance of sound research, strategy and consulting an experienced team to ensure compliance and avoid costly mistakes is critical.

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.

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.

Aphria Fights Shortseller Allegations Of Insider Double Dealing

By Marguerite Arnold
2 Comments

Two reports published by short selling stock firm Quintessential Capital Management and forensic investor research firm Hindenburg Research on December 3, charges that Canadian LP Aphria, has bought overinflated assets in Latin America and in Florida from shell companies owned by company insiders. Added to the lingering controversy is the purchase of the German Nuuvera this spring (a company also partly owned by Aphria brass), and the reports went over like a bombshell. Globally.

However, the story has already spread far beyond one company. And the response in the market has rocked the industry for most of December.

Aphria’s shares tanked, and dragged everyone down with them. Several class action law firms in the United States began promptly looking for aggrieved shareholders.

The response by the firm? A promise of an immediate line-by-line rebuttal, due out in the second week of December. So far, however, despite news of an additional Aphria purchase in Paraguay, the rebuttal report has not been issued.

Why Is This So Damaging? Or Is It?

Aphria’s stocks promptly took a dive that halved their value although they began to recover after Aphria management appointed an independent third party firm to review the claims.

Worse, however, the entire industry saw a hit too. This report affected investor confidence across the industry. And although the hit appears to be temporary, the unfolding scenario is a perfect example of why volatility in the market is scaring away not only more conservative female retail investors but larger institutional ones that the industry is now courting assiduously as medical cannabis begins to be integrated into health systems particularly in Europe.

Why?

Bottom line? As the big cannabis companies are listing on the larger, foreign exchanges, including the NYSE and Deutsche Börse, the scrutiny is getting more direct and granular.Despite the stratospheric market caps of all the major Canadian LPs in particular, not to mention enormous expenditures for the last several years (on property and other acquisitions), the revenue picture, as other stock analysts and publications such as the normally neutral Motley Fool recently pointed out, at least so far does not justify the same. Bulk sales to a hospital, establishing a cultivation or processing facility or even getting import licenses may set one up to do business however, but it is not an automatic route to ongoing and expanding sales. And that is the key to high valuations that are rock solid and beyond the scope of such allegations.

For the moment, that pressure, particularly in global medical markets, is falling first on patients if not doctors. Not the industry.

That said, this has been a major building year. Recreational cannabis has just become legal in Canada. And in Europe, reform is still in the process of happening.

It is also a charge if not frustration that has been growing, however, against all the public cannabis companies as valuations shoot into the stratosphere. Forensic and investigative firms, particularly in Europe and the United States have been focusing on the industry for close to a year now. As a result even when firms successfully rebut charges of fraud, they are looking at different valuations from analysts at least in the short term.

Bottom line? As the big cannabis companies are listing on the larger, foreign exchanges, including the NYSE and Deutsche Börse, the scrutiny is getting more direct and granular.

Are “Short Seller” Reports Unbiased?

For all of the focus on short seller reports in this industry, however, no matter the accuracy of some of their claims, here is the next issue:

Short sellers make money by betting against not only individual firms but the industry itself. They benefit financially in other words, from volatility in the market and arbitraging even small changes in price. Even if their reports cause the same.

Such reports as a result are also not “unbiased” as industry coverage in the press is supposed to be, no matter how much more time sometimes goes into the reporting and preparation of the same.

And no matter that this industry is now going into its fifth year, there is still lingering scepticism that, in the case of Aphria, has so far not only fallen on the individual firm in question, but then rebounds across the industry, unfairly hurting all firms in this space.

Phenova Gets Accreditation For Cannabis Proficiency Testing

Phenova, Inc., a proficiency testing products and reference materials provider based in Golden, Colorado, works with labs and regulatory bodies to develop proficiency testing (PT) programs. According to a press release sent out by the American Association for Laboratory Accreditation (A2LA), Phenova is A2LA’s first ISO/IEC 17043 accredited PT provider for the cannabis marketplace.

According to Ty Garber, director of new business development for the cannabis and food and beverage markets at Phenova, they have been working with A2LA for over a decade in other industries, but the cannabis testing industry is a huge new market for them. “Our Cannabis Proficiency Testing products and services are experiencing high demand across North America and we are fortunate to offer our expertise in proficiency testing to client laboratories and regulatory agencies in their joint efforts to ensure cannabis product quality and safety,” says Garber. “By working with the laboratories and stakeholder agencies, we have been able to develop and operate Proficiency Testing Programs based on real marijuana matrices, especially where the matrix creates specific analytical challenges. This approach has proven to be very beneficial for everyone involved, and we are working diligently to expand these efforts.”

Trace McInturff, senior director of accreditation services at A2LA, says this could help fill a serious need for conformity assessments in accredited cannabis labs. “A2LA is excited to announce the expansion of Phenova’s existing ISO/IEC 17043 Proficiency Testing Provider scope of accreditation to become the first A2LA accredited Proficiency Testing Provider for cannabis,” says McInturff. “This milestone adds to the positive historical relationship between Phenova and A2LA that dates back to 2005 when A2LA implemented a new TNI SSAS program for Proficiency Testing Providers and A2LA performed one of the first assessments of its kind at Phenova.” McInturff also says that A2LA has been instrumental in establishing the initial ILAC Proficiency Testing Provider accreditation requirements which ultimately became the basis for ISO/IEC 17043.

In addition to the “real marijuana matrix PT programs” that Phenova offers in certain states and countries where legal, they also offer alternative PT standards for labs that have obtained or are working on obtaining ISO/IEC 17025 accreditation.
