NCIA Releases Cannabis Testing Policy Guides

By Aaron G. Biros

The National Cannabis Industry Association (NCIA) announced earlier this week the release of two white papers at their Cannabis Business Summit in San Jose, California. The first white paper, dedicated to cannabis testing policy, offers recommendations for state’s addressing cannabis testing, advising them on how to write rules for the testing market.“As wonderful as cannabis is, we’ll face a crisis together as an industry way too soon.  When it happens, the key will be how we respond to it,” says Moss.

The NCIA Policy Council is like a think tank for helping for and shape state and federal level policy related to cannabis. Kurshid Khoja, principal at Greenbridge Corporate Counsel and member of the Policy Council, says this release of the testing policy recommendations demonstrates how we can help shape policy on the state level. “As both an NCIA Board member and a member of the Policy Council, I am really excited about the Council’s work,” says Khoja. “Somewhat under the radar, the Policy Council is establishing itself as the think tank for the cannabis industry. On topics ranging from tax policy to pesticides to international competition, the Policy Council is churning out quality papers to raise awareness and educate policy makers in DC. With the release of its testing policy recommendations this week, the Policy Council is demonstrating that it could also help shape policy on the state level.”

The second white paper is meant to provide guidance to businesses dealing with crisis communications. The manual describes best practices in crisis communications, showing businesses how to identify and avoid potential public communications issues in the cannabis industry.

Jeanine Moss, Crisis Manual Subcommittee Chair of NCIA’s Marketing & Advertising Committee, says the creation of a crisis manual is meant to preempt problems we might face soon in the cannabis industry. “As wonderful as cannabis is, we’ll face a crisis together as an industry way too soon.  When it happens, the key will be how we respond to it,” says Moss. “That’s why we think it is so important for NCIA members to have an easy and practical guide that can not only help protect businesses during a crisis, but also the industry as a whole. This manual will help businesses prevent problems, keep issues from spiraling out of control, and share positive messages during times of stress.”

The guides will be presented this week at the NCIA’s Cannabis Business Summit & Expo in San Jose, California.

The Importance of Medical Cannabis Trials In Europe

By Marguerite Arnold

Calls for more testing have been a watchword of both cannabis reform advocates and opponents alike for many years.

However, now is a really good time for cannabis companies to consider sponsoring medical trials across Europe for their cannabis products. This is why:

The Current Environment On The Ground

Germany is Europe’s biggest consumer of both prescription medications and medical devices dispensed by prescription. It is, as a result, Europe’s most valuable drug market. And ground zero for every international cannabis company right now as a result.Targeting Germany for your latest pharmaceutical product is difficult no matter who you are.

Here, however, are a few problems that face every pharma manufacturer, far beyond cannabis. Targeting Germany for your latest pharmaceutical product is difficult no matter who you are.

  1. The vast majority by euro spending on all drugs and devices dispensed by prescription must be pre-approved. To add to this problem, before they can be prescribed, new drugs must get on the radar of doctors somehow. To put this in stark relief, the entire prescription drug and medical device annual spend is about 120 billion euros a year in Germany. Only 20 billion euros of that, however, may be obtained relatively easily (without pre-approval from an insurer). Preapproval also only comes when there is trialor other scientific evidence of efficacy.
  2. There are strict rules banning the advertising of prescription drugs to patients and highly limiting this outreach to doctors.
  3. There are strict rules prohibiting the use of the word “cannabis” to promote anything.
  4. There is a strong reliance on what is called “evidence-based medicine.” That means that large numbers of doctors and insurance company approvers need to see hard data that this drug or device actually works better than what is currently on the market.

How then, is a new drug supposed to get on the radar of those who prescribe the drug? Or patients?

If this sounds like an impossible situation to navigate, do not despair. There is a way out.

The Impact of the European Medicines Agency

This agency has been much in the news of late. Namely, the British do not want to exclude themselves from the regulatory umbrella of this organization.

Largely unknown outside Europe, this agency actually has a hugeinfluence on how drugs are brought into the region. Specifically, this is the EU-wide agency (aka the EMA) that both regulates all drugs within Europe, but has also, since 2016, been making clinical reports submitted by pharmaceutical companies, available to anyone who asks for them. That includes doctors, members of the public and of course, the industry itself.

In the middle of July, the agency also published a report on the success of its now three-year-old program, including the usage of its entry website. Conveniently written in English, it is possible to easily search new trial data, which, also now must be made public.

Medical trial data, in other words, that can be created by sponsored cannabis company backed trials.

It remains the best way to get patients, doctors and insurance companies familiar with new drugs. Or even new uses for old drugs in the case of cannabis.

Will Trials Move Legalization Discussions?

Of all the established cannabis companies now in operations with producton the ground, GW Pharmaceuticals has learned that this strategy can actually cut both ways.GW logo-2

However,there are no other cannabis companies in the position of GW Pharma – namely with a monopoly on a whole country (the UK), where it alone can legally grow cannabis crops and process the same into medication and further for very profitable export. In addition, even more disturbingly, and clearly an era that is coming to an end, the vast majority of British patients have been excluded from access to cannabis except in the case of GW Pharma products.

The current row over expanded medical use in the UK, in fact, was triggered by two things. The failure of the latest GW Pharma trial for drug resistant epilepsy in Eastern Europe. And the deliberate importation by several desperate families, of good old cannabis (CBD) oil into the UK. No medical processing required.

GW Pharma said their product Epidiolex (for the treatment of childhood epilepsy) is being considered by the European Medicines Agency

However, that is the UK.

Other cannabis companies can take a page out of the company’s handbook. All that is required for faster market entry, is a slightly altered recipe.

By sponsoring cannabis-related trials in each country they want to enter, starting with Germany, cannabis companies can literally put themselves on the medical map.

Why?

Because doctors, patients andother researchers will be easily able to see and access country-specific medical data on each use of cannabis covered by a trial, per EU country. All made possible, of course, by the new open door policy of the EMA.

Growing the Medical Market

While this may sound like an “expensive” proposition, there are really few other alternatives. And with no advertising budget, plus a marketing budget that must include outreach to everyone in the supply chain including doctors, distributors and even pharmacies, the trial approach in the end may be the most efficacious in broadening both the demand and market. Not to mention the cheaper option.

How such a trial strategy might be coordinated at a time when domestic cultivation is still on hold is still a question. However for those companies considering market entry and cultivation bid if not domestic processing strategies for their products is an industry strategy that will pay off in spades.

Its role in the legalization of cannabis as medicine, as well as the speedier introduction of new drugs overall into the European system,cannot be underestimated, even if it is currently underutilized by the cannabis industry specifically now.

Quality Plans for Lab Services: Managing Risks as a Grower, Processor or Dispensary, Part 3

By Dr. Edward F. Askew

Dr. Ed Askew

Editor’s Note: The views expressed in this article are the author’s opinions based on his experience working in the laboratory industry. This is an opinion piece in a series of articles designed to highlight the potential problems that clients may run into with labs. 


In the last two articles, I discussed the laboratory’s first line of defense (e.g. certification or accreditation) paperwork wall used if a grower, processor or dispensary (user/client) questioned a laboratory result and the conflicts of interest that exist in laboratory culture. Now I will discuss the second line of defense that a laboratory will present to the user in the paperwork wall: Quality Control (QC) results.

Do not be discouraged by the analytical jargon of the next few articles. I suggest that you go immediately to the conclusions to get the meat of this article and then read the rest of it to set you on the path to see the forest for the trees.

QC in a laboratory consists of a series of samples run by the laboratory to determine the accuracy and precision of a specific batch of samples. So, to start off, let’s look at the definitions of accuracy and precision.QC Charts can provide a detailed overview of laboratory performance in a well-run laboratory.

According to the Standard Methods for the Examination of Water and Wastewater:

Accuracy: estimate of how close a measured value is to the true value; includes expressions for bias and precision.

Precision: a measure of the degree of agreement among replicate analyses of a sample.

A reputable laboratory will measure the Accuracy and Precision of QC samples in a batch of user samples and record these values in both the analytical test report issued to the user and in control charts kept by the laboratory. These control charts can be reviewed by the user if they are requested by the user. These control charts record:

Accuracy (means) chart: The accuracy chart for QC samples (e.g., LRB, CCV, LFBs, LFMs, and surrogates) is constructed from the average and standard deviation of a specified number of measurements of the analyte of interest.

Precision (range) chart: The precision chart also is constructed from the average and standard deviation of a specified number of measurements (e.g., %RSD or RPD) for replicate of duplicate analyses of the analyte of interest.

Now, let’s look at what should be run in a sample batch for cannabis analyses. The typical cannabis sample would have analyses for cannabinoids, terpenes, microbiological, organic compounds, pesticides and heavy metals.

Each compound listed above would require a specific validated analytical method for the type of matrix being analyzed. Examples of specific matrixes are:

  • Cannabis buds, leaves, oil
  • Edibles, such as Chocolates, Baked Goods, Gummies, Candies and Lozenges, etc.
  • Vaping liquids
  • Tinctures
  • Topicals, such as lotions, creams, etc.

Running QC analyses does not guarantee that the user’s specific sample in the batch was analyzed correctly.

Also, both ISO 17025-2005 and ISO 17025-2017 require the use of a validated method.

ISO 17025-2005: When it is necessary to use methods not covered by standard methods, these shall be subject to agreement with the customer and shall include a clear specification of the customer’s requirements and the purpose of the test and/or calibration. The method developed shall have been validated appropriately before use.

ISO 17025-2017: The laboratory shall validate non-standard methods, laboratory-developed methods and standard methods used outside their intended scope or otherwise modified. The validation shall be as extensive as is necessary to meet the needs of the given application or field of application.

Validation procedures can be found in a diverse number of analytical chemistry associations (such as AOACand ASTM) but the State of California has directed users and laboratories to the FDA manual “Guidelines for the Validation of Chemical Methods for the FDA FVM Program, 2nd Edition, 2015

The laboratory must have on file for user review the following minimum results in an analytical statistical report validating their method:

  • accuracy,
  • limit of quantitation,
  • ruggedness,
  • precision,The user must look beyond the QC data provided in their analytical report or laboratory control charts.
  • linearity (or other calibration model),
  • confirmation of identity
  • selectivity,
  • range,
  • spike recovery.
  • limit of detection,
  • measurement uncertainty,

The interpretation of an analytical statistical report will be discussed in detail in the next article. Once the validated method has been selected for the specific matrix, then a sample batch is prepared for analysis.

Sample Batch: A sample batch is defined as a minimum of one (1) to a maximum of twenty (20) analytical samples run during a normal analyst’s daily shift. A LRB, LFB, LFM, LFMD, and CCV will be run with each sample batch. Failure of any QC sample in sample batch will require a corrective action and may require the sample batch to be reanalyzed. The definitions of the specific QC samples are described later.

The typical sample batch would be set as:

  • Instrument Start Up
  • Calibration zero
  • Calibration Standards, Quadratic
  • LRB
  • LFB
  • Sample used for LFM/LFMD
  • LFM
  • LFMD
  • Samples (First half of batch)
  • CCV
  • Samples (Second half of batch)
  • CCV

The QC samples are defined as:

Calibration Blank: A volume of reagent water acidified with the same acid matrix as in the calibration standards. The calibration blank is a zero standard and is used to calibrate the ammonia analyzer

Continuing Calibration Verification (CCV): A calibration standard, which is analyzed periodically to verify the accuracy of the existing calibration for those analytes.

Calibration Standard: A solution prepared from the dilution of stock standard solutions. These solutions are used to calibrate the instrument response with respect to analyte concentration

Laboratory Fortified Blank (LFB): An aliquot of reagent water or other blank matrix to which known quantities of the method analytes and all the preservation compounds are added. The LFB is processed and analyzed exactly like a sample, and its purpose is to determine whether the methodology is in control, and whether the laboratory is capable of making accurate and precise measurements.

Laboratory Fortified Sample Matrix/Duplicate (LFM/LFMD) also called Matrix Spike/Matrix Spike Duplicate (MS/MSD): An aliquot of an environmental sample to which known quantities of ammonia is added in the laboratory. The LFM is analyzed exactly like a sample, and its purpose is to determine whether the sample matrix contributes bias to the analytical results. The background concentrations of the analytes in the sample matrix must be determined in a separate aliquot and the measured values in the LFM corrected for background concentrations (Section 9.1.3).Laboratories must validate their methods.

Laboratory Reagent Blank (LRB): A volume of reagent water or other blank matrix that is processed exactly as a sample including exposure to all glassware, equipment, solvents and reagents, sample preservatives, surrogates and internal standards that are used in the extraction and analysis batches. The LRB is used to determine if the method analytes or other interferences are present in the laboratory environment, the reagents, or the apparatus.

Once a sample batch is completed, then some of the QC results are provided in the user’s analytical report and all of the QC results should be recorded in the control charts identified in the accuracy and precision section above.

But having created a batch and performing QC sample analyses, the validity of the user’s analytical results is still not guaranteed. Key conclusion points to consider are:

  1. Laboratories must validate their methods.
  2. Running QC analyses does not guarantee that the user’s specific sample in the batch was analyzed correctly.
  3. QC Charts can provide a detailed overview of laboratory performance in a well-run laboratory.

The user must look beyond the QC data provided in their analytical report or laboratory control charts. Areas to look at will be covered in the next few articles in this series.

Centrifugal Partition Chromatography Paves the Way for Safer, More Standardized Cannabidiol Drugs

By Lauren Pahnke
No Comments
Lauren Pahnke

Imagine this: you are taking medication for cancer pain. One day, it works perfectly. The next, you feel no relief. On some days, you need to take three doses just to get the same effect as one. Your doctor can’t be completely positive how much active ingredient each dose contains, so you decide for yourself how much medication to take.

Doesn’t seem safe, right? It is crucial that doctors know exactly what they are prescribing to their patients. They must know that their patients are receiving the exact same dose of medication in their prescription each time they take it, and that their medication contains only the intended ingredients.

consistency is key to creating products that are safe for consumers.In the cannabis industry, lack of certainty on these important factors is a major problem for drug manufacturers as they attempt to incorporate cannabidiol (CBD), a compound found in cannabis that has no psychoactive effects but many medical benefits, into pharmaceutical drugs.

When using these compounds as medications, purity is essential. Cannabis contains a wide variety of compounds. Delta-9 tetrahydrocannabinol (THC) is the most well-known compound and its main psychoactive one1. Safety regulations dictate that consumers know exactly what they are getting when they take a medication. For example, their CBD-based medications should not contain traces of THC.

The cannabis industry greatly needs a tool to ensure the consistent extraction and isolation of compounds. In 2017, the cannabis industry was worth nearly $10 billion, and it is expected to grow $57 billion more in the next decade2. As legalization of medical cannabis expands, interest in CBD pharmaceuticals is likely to grow.

If compounds such as CBD are going to be used in pharmaceutical drugs, consistency is key to creating products that are safe for consumers.

CBD’s Potential

CBD is a non-psychoactive compound that makes up 40 percent of cannabis extracts1. It is great for medical applications because it does not interfere with motor or psychological function. Researchers have found it particularly effective for managing cancer pain, spasticity in multiple sclerosis, and specific forms of epilepsy3.

Figure 1: The chemical structure of cannabidiol.
Figure 1: The chemical structure of cannabidiol.

Other compounds derived from cannabis, such as cannabichromene (CBC) and cannabigerol (CBG), may also be beneficial compounds with medical applications. CBC is known to block pain and inflammation, and CBG is known for its use as a potential anti-cancer agent1.

Along with these compounds that provide medical benefits, there are psychoactive compounds that are used recreationally, such as THC.

“It will definitely be an advantage to have cannabis-based medications with clearly defined and constant contents of cannabinoids,” says Kirsten Müller-Vahl, a neurologist and psychiatrist at Hannover Medical School in Germany.

Creating a Standard Through Centrifugal Partition Chromatography

To obtain purified compounds from cannabis, researchers need to use technology that will extract the compounds from the plant.

Many manufacturers use some sort of chromatography technique to isolate compounds. Two popular methods are high performance liquid chromatography (HPLC) and flash chromatography. These methods have their places in the field, but they cannot be effectively and cost-efficiently scaled to isolate compounds. Instead, HPLC and flash chromatography may be better suited as analytical tools for studying the characteristics of the plant or extract. As cannabis has more than 400 chemical entities4, compound isolation is an important application.

This method is highly effective for achieving both high purity and recovery.Although molecules such as CBD can be synthesized in the lab, many companies would rather extract the compounds directly from the plant. Synthesized molecules do not result in a completely pure compound. The result, “is still a mixture of whatever cannabinoids are coming from a particular marijuana strain, which is highly variable,” says Brian Reid, chief scientific officer of ebbu, a company in Colorado that specializes in cannabis purification.

Currently, there is only one method available to researchers that completely allows them to isolate individual compounds: centrifugal partition chromatography (CPC).

The principle of CPC is similar to other liquid chromatography methods. It separates the chemical substances as the compounds in the mobile phase flow through and differentially interact with the stationary phase.

Where CPC and standard liquid chromatography differs is the nature of the stationary phase. In traditional chromatography methods, the stationary phase is made of silica or other solid particles, and the mobile phase is made of liquid. During CPC, the stationary phase is a liquid that is spun around or centrifuged to stay in place while the other liquid (mobile phase) moves through the disc. The two liquid phases, like oil and water, don’t mix. This method is highly effective for achieving both high purity and recovery. Chemists can isolate chemical components at 99 percent or higher purity with a 95 percent recovery rate5.

“CPC is ideal for ripping a single active ingredient out of a pretty complex mixture,” says Reid. “It’s the only chromatographic technique that does that well.”

The Need for Pure Compounds

High levels of purity and isolation are necessary for cannabis to be of true value in the pharmaceutical industry. Imagine relying on a medication to decrease your seizures, and it has a different effect every time. Sometimes there may be traces of psychoactive compounds. Sometimes there are too much or too little of the compound that halts your seizures. This is not a safe practice for consumers who rely on medications.“It’s hard to do studies on things you can’t control very well.”

Researchers working with cannabis desperately need a technology that can extract compounds with high purity rates. It is hard to run a study without knowing the precise amounts of compounds used. Reid uses a Gilson CPC 1000 system at ebbu for his cannabinoid research. With this technology, he can purify cannabinoids for his research and create reliable formulations. “Now that we have this methodology dialed in we can make various formulations —whether they’re water-soluble, sublingual, inhaled, you name it —with very precise ratios of cannabinoids and precise amounts of cannabinoids at the milligram level,” says Reid.

Kyle Geary, an internist at the University of Illinois at Chicago, is currently running a placebo-controlled trial of CBD capsules for Crohn’s disease. This consistent isolation is helpful for his research, as well. “Ideally, the perfect study would use something that is 100 percent CBD,” says Geary. “It’s hard to do studies on things you can’t control very well.”

The State of the Industry

While CBD is not considered a safe drug compound under federal law in the United States6, 17 states have recently passed laws that allow people to consume CBD for medical reasons7. Half of medicinal CBD users solely use the substance for treatment, a recent survey found8. As the industry quickly grows, it is crucial that consumer safety protocol keeps pace.

In June, the US Food and Drug Administration (FDA) approved the first drug that contains a purified drug substance from cannabis, Epidiolex9. Made from CBD, it is designed to treat Dravet Syndrome and Lennox-Gastaut syndrome, two rare forms of epilepsy. FDA Commissioner Scott Gottlieb said in the news release that although the FDA will work to support the development of high-quality cannabis-based products moving forward, “We are prepared to take action when we see the illegal marketing of CBD-containing products with serious, unproven medical claims. Marketing unapproved products, with uncertain dosages and formulations can keep patients from accessing appropriate, recognized therapies to treat serious and even fatal diseases.”

The industry should be prepared to implement protocols to ensure the quality of their CBD-based products. The FDA has issued warnings in recent years that some cannabinoid products it has tested do not contain the CBD levels their makers claim, and consumers should be wary of such products10. It’s hard to know when or if the FDA will begin regulating CBD-based pharmaceuticals. However, for pharma companies serious about their reputation, there is only one isolation method that creates reliable product quality: CPC.

Food Safety: Do You Know What Is In Your Water?

By Radojka Barycki
No Comments
Radojka Barycki picture

Water is essential for life and it is an important part of agriculture and food manufacturing. Water has many uses in the cannabis industry. Among the most common uses are irrigation, ingredient/product processing and cleaning processes.

Water can be the carrier of pathogenic microorganisms and chemicals that can be transferred to food through agriculture and manufacturing practices. Poor quality water may have a negative impact in food processing and potentially on public health. Therefore, development and implementation of risk management plans that ensure the safety of water through the controls of hazardous constituents is essential to maintain the safety of agricultural and manufactured food or cannabis products.

Chemicals can enter the water stream through several sources such as storm water, direct discharge into fields and city water treatment plans.Although there no current regulations regarding the water used in cannabis cultivation and processing, it is highly recommended that the industry uses potable water as standard practice. Potable water is water that is safe for drinking and therefore for use in agriculture and food manufacturing. In the United States, the Environmental Protection Agency (EPA) sets the standards for water systems under the Safe Drinking Water Act (SDWA.)The regulations include the mandatory levels defined as Maximum Contaminant Levels (MCLs) for each contaminant that can be found in water. Federal Drinking Water Standards are organized into six groups: Microorganisms, Disinfectants, Disinfection Byproducts, Inorganic Chemicals, Organic Chemicals and Radionuclides. The agriculture and food manufacturing industry use the SDWA as a standard to determine water potability. Therefore, water testing forms part of their routine programs. Sampling points for water sources are identified, and samples are taken and sent to a reputable laboratory to determine its quality and safety.

Microbiological Testing

Determining the safety of the water through microbiological testing is very important. Pathogens of concern such as E. coli, Salmonella, Cryptosporidium parvum and Cyclospora sp. can be transmitted to food through water. These pathogens have been known to be lethal to humans, especially when a consumer’s immune system is compromised (e.g. cancer patients, elderly, etc.) If your water source is well, the local state agency may come to your facility and test the water regularly for indicator organisms such as coliforms. If the levels are outside the limit, a warning will be given to your company. If your water source is the city, regular testing at the facility for indicator microorganisms is recommended. In each case, an action plan must be in place if results are unfavorable to ensure that only potable water is used in the operations.

Chemical Testing (Disinfectants, Disinfection Byproducts, Inorganic Chemicals, Organic Chemicals and Radionuclides) 

Chemicals can enter the water stream through several sources such as storm water, direct discharge into fields and city water treatment plans. Although, there are several regulations governing the discharge of chemicals into storm water, fields and even into city water treatment plants, it is important that you test your incoming water for these chemicals on a regular basis. In addition, it is important that a risk assessment of your water source is conducted since you may be at a higher risk for certain components that require testing. For example, if your manufacturing facility is near an agricultural area, pesticides may enter the surface water (lakes, streams, and rivers) or the aquifer (ground water) through absorption into the ground or pollution. In this case, you may be at higher risk for Tetrahalomethanes (THMs), which are a byproduct of pesticides. Therefore, you should increase the testing for these components in comparison to other less likely to occur chemicals in this situation. Also, if your agriculture operation is near a nuclear plant, then radionuclides may become a higher risk than any of the other components.

GMPFinally, in addition to the implementation of risk management plans to ensure the safety of water, it is highly recommended that companies working in food manufacturing facilities become familiar with their water source to ensure adequate supply to carry on their operations, which is one of the requirements under the 21 CFR 117. Subpart B – Current Good Manufacturing Practices (cGMPs) for food manufacturers under the Preventive Controls for Human Foods Rule that was enacted under the Food Safety Modernization Act in 2015. Also, adequate supply is part of the Good Agricultural Practices (GAP) The EPA has created a program that allows you to conduct a risk assessment on your water source. This program is called Source Water Protection. It has six steps that are followed to develop a plan that not only protect sourcing but also ensures safety by identifying threats for the water supply. These six steps are:

  1. Delineate the Source Water Protection Area (SWPA): In this step a map of the land area that could contribute pollutants to the water is created. States are required to create these maps, so you should check with local and/or state offices for these.
  2. Inventory known and potential sources of contamination: Operations within the area may contribute contaminants into the water source. States usually delineates these operations in their maps as part of their efforts to ensure public safety. Some examples of operations that may contribute to contaminants into the water are: landfill, mining operations, nuclear plants, residential septic systems, golf courses, etc. When looking at these maps, be sure that you verify the identified sources by conducting your own survey. Some agencies may not have the resources to update the maps on a regular basis.
  3. Determine the susceptibility of the Public Water Source (PWS) to contaminate sources or activities within the SWPA: This is basically a risk assessment. In here you will characterize the risk based on the severity of the threat and the likelihood of the source water contamination. There are risk matrices that are used as tools for this purpose.
  4. Notify the public about threats identified in the contaminant source inventory and what they mean to the PWS: Create a communication plan to make the State and local agencies aware of any findings or accidents in your operation that may lead to contamination of the PWS.
  5. Implement management measures to prevent, reduce or eliminate risks to your water supply: Once risks are characterized, a plan must be developed and implemented to keep risks under control and ensure the safety of your water.
  6. Develop contingency planning strategies that address water supply contamination or service interruption emergencies: OSHA requires you to have an Emergency Preparedness Plan (EPP). This plans outlines what to do in case of an emergency to ensure the safety of the people working in the operation and the continuity of the business. This same approach should be taken when it comes to water supply. The main questions to ask are: a) What would we do if we find out the water has been contaminated? b) What plan is in place to keep the business running while ensure the safety of the products? c) How can we get the operation back up and running on site once the water source is re-stablished?

The main goal of all these programs is having safe water for the operations while keeping continuity of the business in case of water contamination.

Collaborative Health Model to Advance Cannabis Research

By Rob Adelson

Rob Adelson

The projected growth of the legal cannabis market is astounding. According to a report from BDS Analytics, the industry is expected to grow from $9.2B to $47.3B in 2027 in North America, with medical cannabis contributing 33% of that overall growth. While this number is impressive for an industry still in its infancy, I have reason to believe it can be much higher.

In the pharmaceutical industry, treatment of pain and insomnia represent an annual revenue exceeding $140B; concurrently, studies have shown cannabis to be an effective treatment for both conditions. If medical cannabis can capture 10% of that revenue over the next ten years, it essentially doubles the current estimates mentioned above.

So, what stands in our way? Education.

To gain acceptance from the medical community, physicians need to better understand the plant and its therapeutic benefits. To do so, they need more substantial data to prove cannabis’ efficacy before prescribing it to their patients. However, federal illegalities have prevented government-mandated clinical studies, but I believe there’s another way.

By adopting a collaborative health care model, patients and caregivers can work together to track the effectiveness of their cannabis treatments and share their learnings with the larger medical community.  With the right tools in place, we can fast-track the research process and provide physicians and politicians with the information they need to make this medicine more approachable and accessible to those who could benefit from it.

By harnessing the power of the community, we can apply learnings from one patient’s cannabis use to help countless others.The Spine Patient Outcomes Research Trial (SPORT) was a five-year study consisting of approximately 2500 patients with back and spine conditions. Participants entered qualitative data into an online portal, including post-surgical results and patient outcomes, to provide a comprehensive insight into treatment methods and their efficacy. Today, others suffering with those same conditions can enter their personal information into an online calculator and receive a prospective treatment plan. Together, patients and their doctors can view results and build a customized plan using more informed decisions about the available treatment options.

Another example comes from OpenNotes– an exploratory study that provides patients with full access to their medical files and the opportunity to input comments about their doctor visits and prognosis and make corrections related to the care they received. Results showed that this process helped patients retain a better understanding of their condition which improved their decision making and resulted in increased adherence to treatment plan protocols because they had greater trust with their doctors.Not only will this improve the patient experience by providing a safer, more sustainable treatment option, it also provides a very significant financial opportunity.

I believe the cannabis industry can take a leadership role in empowering patients to become active participants in their own treatment, while also sharing knowledge with the larger patient and physician communities. In fact, this core belief was the reason I founded Resolve Digital Health. Data-empowered patients not only make better decisions but also enjoy a greater feeling of control over their treatment. The power of collaborative healthcare grows exponentially when the data is shared to educate a broader group. By harnessing the power of the community, we can apply learnings from one patient’s cannabis use to help countless others.

Businesses within the cannabis industry can also leverage this data to create new products and services. For example, insights as to what products work best for certain conditions can help LP’s improve their product offerings and guide recommendations from dispensaries. Through product innovation, companies can make cannabis more accessible to a larger group of patients, who may be currently taking pharmaceuticals. Not only will this improve the patient experience by providing a safer, more sustainable treatment option, it also provides a very significant financial opportunity.

Ultimately, knowledge is power. When patients are empowered to make educated decisions about their health care and doctors are more tuned into the patient-tested cannabis treatment options, it’s a win-win for everyone.

Now that governments are legalizing cannabis around the world, the question looms for cannabis businesses seeking legitimacy in the new industry: what safety standards should apply? This question is more difficult as different jurisdictions grapple with defining and implementing legal requirements and struggle to keep up with the pace of growth.

For visionary cannabis business, it makes sense to anticipate requirements – not only from governments, but also from consumers and partners. Most regulations currently focus on security and basic health issues but, in the long-term, the industry that may offer the best model for cannabis businesses isn’t pharmaceuticals, but food. Cannabis (especially edibles) share similar hazards and traceability challenges with food products, so taking the lead from the food industry will be much more applicable and could offer greater benefits.

Companies that achieve the highest and most flexible certification will enjoy a crucial competitive advantage when it comes to winning market share, popularity and consumer trust. Let’s take a quick look at the different options of food safety (and quality) certifications that cannabis businesses may consider. But first, let’s clarify two important definitions that are necessary to understand the food industry.

Basic Concepts from the Food Industry

The first acronym you should be aware of is GFSI, the Global Food Safety Initiative. GFSI is a food industry-driven global collaboration body created to advance food safety. When it comes to understanding GFSI, the important part to note is that certifications recognized by GFSI (like SQF, FSSC 22000, and BRC) are universally accepted. Companies operating under GFSI-recognized certifications open the most doors to the most markets, providing the highest potential for growth. For this reason, cannabis companies should be aware of and seriously consider seeking GFSI certifications

HACCPSecondly, many food safety programs are built around Hazard Analysis Critical Control Points, or HACCP. While many people may talk about HACCP like it’s a certification in and of itself, it is not actually a certification like the others on this list, but rather a methodology that helps companies systematically identify and control biological, chemical, and physical hazards that may arise during food production, handling, and distribution. Companies that adopt this methodology end up with a HACCP plan, which must then be followed at all times to avoid and address health and safety issues. It’s often required for food businesses and is generally required in most of the world, except where ISO 22000 is more common, primarily in Europe and countries whose primary export market is European. Since HACCP plans are also incorporated into most of the other achievable certifications, developing a HACCP program early will build a strong foundation for higher levels of certification.

Certifications for the Cannabis Industry

Now that we understand the basics of GFSI and HACCP, we can see how the certifications that have been developed by and for the food industry may apply to cannabis companies – and which you should consider necessary for your business.

GMP: Good Manufacturing Practice Certification

GMP (or sometimes cGMP) certification requires that companies abide by a set of good manufacturing processes for food and beverage products, pharmaceuticals, cosmetics, dietary supplements and medical devices. Since it really only covers basic sanitation and employee hygiene, it is considered the lowest level of certification in the industry. It is not recognized by GFSI, but GFSI does require all the standard benchmarks of a GMP be met before granting GFSI certification.

While GMP certification is often required, it is far below the standard that should be upheld by any serious businesses. It doesn’t cover many of the different types of hazards associated with food production – that I have argued will become increasingly relevant to cannabis producers – and doesn’t provide a systematic approach to identifying and controlling hazards like a HACCP program would. It’s really just about providing the basic procedures and checks to ensure that the facility is clean and that employees aren’t contaminating the products.GMP

Final Verdict: Recommended, but as the bare minimum. GMP is not sufficient on its own to adequately control the risk of recalls and foodborne illness outbreaks, and it limits a company’s market potential because it lacks the GFSI worldwide stamp of approval.

Some companies consider GMP certification a good place to start if you’re on a tight deadline for distribution in markets where only GMP is required by regulators. I would argue that striving for the minimum standards will be costly in the long run. Health, safety and quality standards are the foundations upon which winning companies are built. It’s critical to develop a corporate culture that will lead to GFSI-recognized programs without major organizational overhaul. Start on the right foot and set your sights higher – obtain a certification that will stand the test of time and avoid the pain and risks of trying to change entrenched behaviors.

SQF: Safe Quality Food Program Certification

SQF is my number one recommendation as the best certification for the cannabis industry. One of the most common certifications in North America, SQF is a food safety management system recognized by retailers and consumers alike. It is administered by the Food Marketing Institute (FMI) and, importantly, recognized by GFSI, which gives companies a huge competitive edge. SQF focuses on the whole supply chain.

SQF was also the first to develop a cannabis program and is currently the leader in this market segment. It is also the scheme that best integrates food safety with quality. Since it is recognized worldwide, SQF provides the greatest leverage to accelerate a company’s growth. Once obtained, products with SQF certification can often jump the queue to enter different regulatory markets.

Final verdict: Highly recommended. A cannabis company with an SQF certification has the greatest advantage because it offers the broadest worldwide reach and keeps companies a step ahead of competitors. It’s also achievable – just this past April, Curaleaf Florida ostensibly became the first cannabis company to achieve SQF certification. It is tough, but fair and practical.

Other Certification Standards

SQF is the top certification that should be considered by cannabis companies, especially outside of Europe. However, the food industry has several other major types of standards that, at this time, have limited relevance to the cannabis industry today. Let’s take a quick look.

When considering GFSI-recognized programs, the main choice for food companies is between SQF, which we’ve covered, and BRC (the British Retail Consortium Certification). BRC has the most in common with SQF but, while SQF was originally developed for processed foods, BRC was developed in the UK for meat products. Today, they are quite similar, but BRC doesn’t focus quite as much on the quality component as SQF does. While BRC could be a good option, they don’t have a program for cannabis and, thus far, do not appear to be as friendly toward the cannabis industry.The food industry has a lot to offer cannabis companies that are anticipating future regulatory changes and market advantages 

Across the pond, there are a few other certification standards that are more common than SQF. One of these is ISO 22000, which is the certification for the food-related standard created by the International Organization for Standardization (ISO) in Europe. It is not recognized by GFSI but is the primary system used in Europe. If your market is exclusively in the EU, it might be a good choice for you in the future. However, to date, there is no indication that any cannabis company has achieved ISO 22000 certification. Some cannabis companies have attained certification for other ISO standards like ISO 9001:2015, which specifies requirements for quality control systems, and ISO/IEC 17025 for laboratory testing. These are generally more relevant for the pharmaceutical industry than food and beverage, but still apply to cannabis.

There is the perception that cannabis is more accepted in EU countries like the Netherlands, but the regulatory attitude to cannabis is complicated. In the Netherlands, for example, cannabis isn’t actually legal – “coffee shops” fall under a toleration policy that doesn’t include regulation. Medical cannabis in the Netherlands is all produced by one supplier and several countries in the EU allow for licensed distribution and import, but not domestic production. Various EU countries are trying to keep up with the legalization trend, however. The Czech Republic, Germany, and others all recently introduced legislation for domestic production of cannabis for medical use. For companies with their eye on the EU, it is crucial to watch which regulatory requirements will be implemented in each market and how.

The last certification standard to mention is the result of a compromise between ISO and the more HACCP oriented programs like SQF. FSSC 22000 (Food Safety System Certification) tries to address the gaps between ISO 22000 and GFSI-recognized certifications by introducing another component called PAS 220. Since it is recognized by GFSI, FSSC 22000 is starting to get more traction in the food industry because it makes products a bit easier to export to the EU. FSSC 22000 satisfies the EU ISO standards but isn’t as closely tied to HACCP. We will be keeping an eye on this one.

Final Takeaway

The food industry has a lot to offer cannabis companies that are anticipating future regulatory changes and market advantages – but it’s difficult for cannabis companies to understand all the options available and how each apply to their specific products. While markets adjust beyond the preliminary issue of legality, it’s crucial for companies to look forward and comply with safety and quality standards like SQF. Companies who strive for SQF certification (or other GFSI-recognized certifications as they become available) will find themselves far better prepared to seize market share as cannabis markets blossom.

Epidiolex-GW

According to a press release, the U.S. Food and Drug Administration (FDA) approved GW Pharma’s drug Epidiolex for the treatment of rare forms of epilepsy. Just a few months ago, news broke of a very encouraging FDA panel assessment, which indicated a positive outlook for the drug’s approval.

In the press release, FDA Commissioner Scott Gottlieb, M.D appeared to indicate an open willingness to explore the medical benefits of cannabis. “This approval serves as a reminder that advancing sound development programs that properly evaluate active ingredients contained in marijuana can lead to important medical therapies,” says Gottlieb. “And, the FDA is committed to this kind of careful scientific research and drug development.” He went on to add:FDAlogo

Controlled clinical trials testing the safety and efficacy of a drug, along with careful review through the FDA’s drug approval process, is the most appropriate way to bring marijuana-derived treatments to patients. Because of the adequate and well-controlled clinical studies that supported this approval, prescribers can have confidence in the drug’s uniform strength and consistent delivery that support appropriate dosing needed for treating patients with these complex and serious epilepsy syndromes. We’ll continue to support rigorous scientific research on the potential medical uses of marijuana-derived products and work with product developers who are interested in bringing patients safe and effective, high quality products. But, at the same time, we are prepared to take action when we see the illegal marketing of CBD-containing products with serious, unproven medical claims. Marketing unapproved products, with uncertain dosages and formulations can keep patients from accessing appropriate, recognized therapies to treat serious and even fatal diseases.

According to the press release, the drug was studied in three randomized, double-blind, placebo-controlled clinical trials with 516 patients who have either Lennox-Gastaut syndrome or Dravet syndrome, the two rare forms of epilepsy the drug is now approved to treat. Epidiolex is an anti-epilepsy drug, taken in a syrup form, with the main active ingredient being cannabidiol (CBD), and less than 0.1 % THC.

Top 10 Common Findings Detected During Cannabis Laboratory Assessments: A Guide to Assist with Accreditation

By Tracy Szerszen
No Comments

With the cannabis industry growing rapidly, laboratories are adapting to the new market demand for medical cannabis testing in accordance to ISO/IEC 17025. Third-party accreditation bodies, such as Perry Johnson Laboratory Accreditation, Inc. (PJLA), conduct these assessments to determine that laboratories are following relevant medical cannabis testing standard protocols in order to detect potency and contaminant levels in cannabis. Additionally, laboratories are required to implement and maintain a quality management system throughout their facility. Obtaining accreditation is a challenge for laboratories initially going through the process. There are many requirements outlined in the standard that laboratories must adhere to in order to obtain a final certificate of accreditation. Laboratories should evaluate the ISO 17025 standard thoroughly, receive adequate training, implement the standard within their facility and conduct an internal audit in order to prepare for a third-party assessment. Being prepared will ultimately reduce the number of findings detected during the on-site assessment. Listed below is research and evidence gathered by PJLA to determine the top ten findings by clause specifically in relation to cannabis testing laboratories.
