Why Does GDPR Matter for The Cannabis Industry?

By Marguerite Arnold
2 Comments

The global cannabis industry is hitting thorny regulatory challenges everywhere these days as the bar is raised for international commerce. First it was recognition that the entire production industry in Canada would basically have to retool to meet European (medical and food) standards. And that at least for now for the same reasons, American exports are basically a no go.

However, beyond this, the battle over financial reporting and other compliance of a fiscal kind has been a hot topic this year on European exchanges.

As of this summer, (and not unrelated to the other two seismic shifts) there is another giant in the room.

If you haven’t heard about it yet, welcome to the world of EU GDPR (European Union General Data Privacy Regulation).

The German version is actually Europe’s highest privacy standard, which means for the cannabis industry, this is the one that is required for operations here across the continent if you are in this business.

What is it, and what does it mean for the industry?

GDPR – The Elevator Pitch

Here is why you cannot ignore it. The regulation affects bankers as much as growers, distributors as much as producers and of course the entire ecosystem behind medical production and distribution across Europe and actually far beyond it. Starting of course, with patients but not limited to them. The law in essence, applies to “you” whoever you are in this space. That is why it becomes all that much more complicated in the current environment.

While this is complex and far reaching, however, there are a couple of ways to think about this regulation that can help you understand it and how to manage to it (if not innovate with it).

The first is, to American audiences at least, that GDPR is sort of like HIPAA, the federal American privacy civil rights statute that governs medical privacy law. Except, of course, this being Europe, it is far more robust and far reaching. It touches every aspect of electronic privacy including data storage, retention, processing and security that is applicable to modern life. And far, far, beyond just “patients.”

On the marketing side, GDPR is currently causing no end of headaches. Broadly, the legislation, which came into force this year, with real teeth (4% of global revenues if you get it wrong), applies to literally every aspect of the cannabis industry for two big reasons beyond that. Medical issues, which are the only game in town right now in Europe (and thus require all importers to also be in compliance) and financial regulatory requirements.

The requirements in Germany are more onerous than they are in the rest of Europe. Therefore, they also affect the cannabis industry in a big way, especially since there is at this point a great deal of European cultivation with the German (and now British) medical market in mind. Further Germany is becoming European HQ for quite a few of the Canadian LPs. That means German standards apply.

The UK, for those watching all Brexit events with interest, will also continue to be highly affected by this. Whether it stays in the EU or not, it must meet a certain “trusted nation” status to be able to transact with the continent in any kind of favoured nation status.

Bottom line? It is big and here and expensive if you screw it up. If considering doing any kind of business with European customers, start hitting the books now. Large mainstream media organizations in the United States and Canada right now are so afraid of the consequences of getting this wrong that they have blocked readership from Europe for the present. Large financial institutions also must not only be in compliance but compliance of companies also guides their investment mandates on the regulatory front.

For all of these reasons, the cannabis industry would do well to take note.

What Does This Mean for The Cannabis Industry?

The Canadian and rest of the global industry is still struggling with compliance and this will have some interesting repercussions going forward.patient data must be handled and stored differently

Immediately, this means that all websites that are targeted to German eyes (read Canadian LPs and international, even English-only press) should hire German side compliance experts for a quick GDPR audit. There are few European experts at this point, and even fewer foreign ones. It is worth a call around to find out who is doing this auf Deutschland and bite the bullet.

It also means that internally, patient data must be handled and stored differently. And furthermore, it is not just “patients” who have this right, but everyone who transacts with your electronic or other presence. That includes consumers, subscribers to email newsletters and other stakeholders in the industry.

As the cannabis industry also starts to embrace technology more fully, it will also have highly impactful influence on what actually passes for a compliant technology (particularly if it is customer facing) but not limited to the same.

On the marketing side, GDPR is currently causing no end of headaches. Starting with PR and customer outreach teams who are trying to figure out how much of their master mailing lists they can keep and which they cannot. On this front, Mail Chimp is undeniably the go-to right now and has also implanted easy to understand and use technology that is being adopted by European marketers and those targeting Europe.

Stay tuned for more coverage on GDPR as we cover how data protection and privacy regulations will impact cannabis businesses, their marketing and outreach, plus service design efforts (in particular to patients) and other areas of interest.

Food safety incidents can be prevented. However, prevention requires planning, which requires the effort of everyone in a company to create a culture of quality and food safety. How exactly do you plan for food safety? Food safety planning implies the building of a food safety management system. Food safety management systems allow for an efficient management of hazards that may be present in the food by the development and implementation of pre-requisite programs (PRPs) and a food safety plan, while supported by management commitment. So, let’s take a closer look at each of these building blocks:Radojka Barycki will lead a plenary session titled, “Cannabis: A Compliance Revolution” at the 2018 Food Safety Consortium | Learn More

Management Commitment

The development and implementation of a food safety management system requires financial, equipment, and technically sound personnel in order to be successful and sustainable. The management team of any cannabis product manufacturer must be committed to food safety, so the needed resources to develop and implement a food safety management system are provided. Management commitment creates a culture within the operation that supports, sustains and continuously improves food safety. 

Pre-Requisite Programs (PRPs) 

Pre-requisite programs are procedures that establish the minimal operations conditions to produce safe and quality products. Pre-requisite programs are the foundation of food safety and must be developed and implemented prior to creating a food safety plan. They keep potential hazards from becoming serious enough to adversely impact the safety of products produced. Pre-requisite programs include but are not limited to:

  • Document Control
  • Supplier Verification Programs
  • Raw Material Receiving (ingredients, processing aids and packaging)
  • Good Manufacturing Practices (GMPs)
  • Preventative Maintenance (PM) Program
  • Calibration Program
  • Integrated Pest Management (IPM)
  • Environmental Monitoring Programs (EMPs)
  • Water Management Programs (WMPs)
  • Allergen Management Program
  • Standard Sanitation Operating Procedures (SSOPs)
  • Standard Operating Procedures (SOPs)
  • Storage and Transportation Procedures
  • Crisis Management
  • Traceability
  • Recall
  • Record keeping
  • Waste Management
  • Training

Food Safety Plan (FSP)As you can see, food safety planning requires the development and implementation of a lot of programs.

A food safety plan is a documented systematic approach that follows the Codex Alimentarius HACCP Principles to identify, prevent and minimize to an acceptable level or control hazards that may be present in food and that can cause an illness or injure the consumer. The first step in this systematic approach is the formation of a food safety team, which main responsibility is to identify the scope of the food safety plan and to oversee all of the activities associated with the plan (e.g. monitoring, verification, validation, etc.) After the food safety team is formed, the steps outlined below are followed in order (systematically):

  1. Product Description
  2. Product Intended Use
  3. Development of the flow diagram
  4. Verification of the flow diagram
  5. Conduct a Hazard Analysis
  6. Identify Critical Control Points (CCPs) or Preventive Controls
  7. Establish Critical Limits
  8. Monitor Critical Limits
  9. Establish Corrective Actions
  10. Establish Verification Procedures
  11. Establish Record Keeping Procedures

As you can see, food safety planning requires the development and implementation of a lot of programs. Therefore, I highly recommend that you hire a food safety consultant that can guide you through this process.

Cannabis producers are making large investments in new technologies to improve their plant varieties, production know-how and product formulations. At the same time, producers are working hard to create and promote more compelling, top-of-mind brand identities for their improved products. The series concludes with a 9-point outline of specific steps cannabis producers need to consider taking to protect their key intellectual property assets. 

The value of these investments cannot be realized if competitors are allowed to copy and exploit the producer’s successes. Canada’s intellectual property laws can and should be used to protect cannabis producers from such predation. Invoking Canada’s laws to this end is not difficult and does not have to be expensive. It does, however, require specific, deliberate and early action.

This series of articles outlines the principal means of protecting intellectual property rights in the core technologies and marketing programs of cannabis companies. The series also highlights what any cannabis company must do to ensure that its own activities do not run afoul of another’s rights. No company wants to begin a new venture only to face a lawsuit for intellectual property infringement.

The series concludes with a 9-point outline of specific steps cannabis producers need to consider taking to protect their key intellectual property assets.

Trade Secrets: Protection For Confidential Know How

A trade secret is specific, commercially valuable information and know-how that is kept confidential within the company and cannot generally be reversed-engineered by outsiders. A trade secret provides protection over any type of information or know-how and is not subject to any expiry date. Trade secret protection is lost only when the information or know-how becomes available to the public.

As a best practice, defining the trade secret in a confidential document can be useful as a way of restricting access to the secretCannabis producers generate all kinds of valuable know-how that cannot be appreciated simply from an inspection of the vended product. Examples would include methods of crossbreeding, cultivation, harvesting, extraction and processing. Customer lists and other internal business structures and information may also qualify as trade secrets.

There are no statutory pre-conditions that must be met to obtain a trade secret. A trade secret is acquired simply upon the generation of valuable information or know-how that is kept confidential. As a best practice, defining the trade secret in a confidential document can be useful as a way of restricting access to the secret, and as evidence in proceedings as to the scope of the trade secret (an issue that is frequently in dispute in such cases).

For the trade secret to be maintained, the producer will need to take steps to ensure that access to the know-how and associated documents is restricted only to those who need to know the secret for purposes of carrying out their functions at the company. All personnel with access to the trade secret will need to be bound to confidence by employment agreement and/or by separate contract. When employees leave, they ought to be reminded of their obligations of confidentiality and must be prohibited from removing any documentation regarding the trade secret from the company. All outside companies who need access to the secret must sign non-disclosure agreements. It is typical for owners of trade secrets to be vigilant in their market surveillance and to engage private investigators when they suspect a trade secret has been stolen.

A trade secret’s very confidentiality provides its principal value. A competitor cannot copy what it has no ability to discern. However, when someone with access to the secret ‘goes rogue’, such as by using the know-how for his or her own account or for that of a new employer, the owner of the trade secret must act quickly and bring the matter before the Court. The Court has a broad discretion to stop the rogue and any persons or companies who learn the secret from the rogue from further dissemination or exploitation of the trade secret. The Court also has a broad discretion to craft an appropriate remedy to compensate the trade-secret owner for the wrong. If the action is brought before the trade secret is broadly disseminated, the trade secret may be reinstated and enforceable in the future. If the owner of the secret acts too slowly and the dissemination of the trade secret becomes too broad, the trade secret may be lost forever.

Adopting the use of trade secrets to protect know-how in the cannabis business does suffer from the fragility of the right itself. One disclosure, however inadvertent, can destroy the protection. In addition, a trade secret will not protect a company from a competitor who independently derives the know-how. Further, theft of the trade secret can be difficult to spot because, by its nature, the trade secret is exploited within the walls of the competitor company and is not evident in the marketed product. The owner of the secret will need to watch its competitors for telltale shifts in business direction and product offerings, particularly when those competitors hire the ex-employees of the owner of the trade secret. It is typical for owners of trade secrets to be vigilant in their market surveillance and to engage private investigators when they suspect a trade secret has been stolen.

Editor’s Note: In part 2 of this series, which will be published next week, Richard Naiberg will take a closer look at patents and how business can protect new and inventive technology in Canada’s cannabis industry. Stay tuned for more!

Safety & Efficacy: Ensuring Dosing Accuracy for Infused Products

By Amy Davison
No Comments

Complications with dosing inaccuracies in the cannabis industry has always been a hot topic. In 2014, The Cannabist tested several Colorado infused products only to find that the results were different from what was indicated on the label. While the industry has come a long way at the state level since then, a study published in The Journal of the American Medical Association this past November found that 26 percent of CBD products sold online contained less CBD than the label. Similar to when you buy a bottle of wine or ibuprofen, people should be able to trust product labels.

There are processes that cannabis-infused product manufacturers can adopt to solve this issue. Incorporating process validation establishes reproducible customer experiences while in-process controls create product consistency and potency reliability. These operational and compliance techniques originated in the pharmaceutical industry and will undoubtedly become the future gold standard for best practices with cannabis manufacturers.

Product testing alone cannot assess quality for an entire lot or batch of product; therefore, each step of the manufacturing process must be controlled through Good Manufacturing Practices (GMP). Process validation is an aspect of GMPs used by the pharmaceutical industry to create consistency in a product’s quality, safety and efficacy. There are three main stages to process validation: process design, process qualification and continued process verification. Implementing these stages ensures that quality, including dosing accuracy, is maintained for each manufactured batch of product.

Validation: Step 1

Process design, the first phase of process validation, defines the manufacturing process based on previous product development and process research. The appropriate equipment, instruments and materials are selected as part of process design. Both standard operating procedures for equipment and operations as well as batch records for manufacturing steps are also finalized during this phase. The batch record must include critical process parameters (CPP), the parameters that must be maintained in order to produce product that consistently meets specified criteria. Mixing speed and time, temperature, pressure and flow rate are examples of common CPP. Training production personnel is also defined and performed as part of process design. Operators are trained on operating procedures and batch records in order to learn how to make the product successfully.

Validation: Step 2

Process qualification, the next stage of process validation, is performed to evaluate the capability of a process for reproducible and robust manufacturing. Because reproducibility of a process cannot be fully assessed with a single batch, evaluation is typically performed on a minimum of three separate batches. For each batch included in the process qualification, the frequency and number of samples are increased over normal sampling to provide a more thorough assessment of each batch. The testing includes visual inspection for defects as well as quantitative tests such as weight or volume and potency. In addition to composite sampling, which is performed by combining samples from multiple time points throughout a batch (e.g. beginning, middle and end) to assess a batch as a whole, stratified sampling is performed. Stratified samples are taken from specified points throughout a batch, and rather than being combined, the samples are tested separately to indicate consistency throughout a given batch.

The Stratos product lineup- validation helped produce each of these consistently.

In addition to evaluating the reproducibility of a process, tests for robustness are performed during process qualification to demonstrate how changes in a process may impact the product. It is important to use different operators for performing manufacturing steps to ensure changes in personnel do not affect product quality. Switching out equipment and instruments will also reveal any sensitivities in a process. For example, when a different oven, mixer or tablet press is used, are the appearance, texture and potency impacted? If the product remains the same, that points toward the process being robust. Challenging the CPP will also provide important feedback regarding a process. If a step requires a temperature range of 50° – 70°C, it is recommended that the process be tested at the low end and high end of the range, to ensure the final product meets all required specifications. If the range assigned to a unit’s gross weight is 500 g ± 5%, then testing at 475 g and 525 g will offer more insight into how much variance the process truly can withstand.

Validation: Step 3

Once the process has been assessed for reproducibility and robustness, it transitions to continued process verification, which is the third and final stage of Process Validation. Performance of quality checks during each batch for the life of a product is part of this final stage. For infused products such as tablets, these checks include appearance – the tablets are the color and shape indicated by the batch record and they include the required imprint(s); weight – the tablets are within the specified weight range, which indicates correct tablet size and consistency of ingredients; hardness – tablets will dissolve/disintegrate for proper dosing; and friability – tablets will withstand stress of routine handling.

As your company grows in manufacturing volume, each of these three steps will become critical to safeguard against any inconsistencies. As we know in this industry, our most valuable asset is our license and success can be negatively impacted based on meeting compliance. Dedicating an internal role within quality and compliance will serve to future-proof your business against additional rules and regulations that are likely to come.

The Four Pillars of Cannabis Processing

By Christian Sweeney
2 Comments
extractiongraphic

Cannabis extraction has been used as a broad term for what can best be described as cannabis processing. A well-thought-out cannabis process goes far beyond just extraction, largely overlapping with cultivation on the front-end and product development on the back-end1. With this in mind, four pillars emerge as crucial capabilities for developing a cannabis process: Cultivation, Extraction, Analytics and Biochemistry.

The purpose and value of each pillar on their own is clear, but it is only when combined that each pillar can be optimized to provide their full capacities in a well-designed process. As such, it is best to define the goals of each pillar alone, and then explain how they synergize with each other.

At the intersection of each pillar, specific technology platforms exist that can effectively drive an innovation and discovery cycle towards the development of ideal products.Cultivation is the foundation of any horticultural process, including cannabis production. Whether the goal be to convert pigments, flavors or bioactive compounds into a usable form, a natural process should only utilize what is provided by the raw material, in this case cannabis flower. That means cultivation offers a molecular feedstock for our process, and depending on our end goals there are many requirements we may consider. These requirements start as simply as mass yield. Various metrics that can be used here include mass yield per square foot or per light. Taken further, this yield may be expressed based not only on mass, but the cannabinoid content of the plants grown. This could give rise to a metric like CBD or THC yield per square foot and may be more representative of a successful grow. Furthermore, as scientists work to learn more about how individual cannabinoids and their combinations interact with the human body, cultivators will prioritize identifying cultivars that provide unique ratios of cannabinoids and other bioactive compounds consistently. Research into the synergistic effect of terpenes with cannabinoids suggests that terpene content should be another goal of cultivation2. Finally, and most importantly, it is crucial that cultivation provide clean and safe materials downstream. This means cannabis flower free of pesticides, microbial growth, heavy metals and other contaminants.

Extraction is best described as the conversion of target molecules in cannabis raw material to a usable form. Which molecules those are depends on the goals of your product. This ranges from an extract containing only a pure, isolated cannabinoid like CBD, to an extract containing more than 100 cannabinoids and terpenes in a predictable ratio. There are countless approaches to take in terms of equipment and process optimization in this space so it is paramount to identify which is the best fit for the end-product1. While each extraction process has unique pros and cons, the tunability of supercritical carbon dioxide provides a flexibility in extraction capabilities unlike any other method. This allows the operator to use a single extractor to create extracts that meet the needs of various product applications.

Analytics provide a feedback loop at every stage of cannabis production. Analytics may include gas chromatography methods for terpene content3 or liquid chromatography methods for cannabinoids 3, 4, 5. Analytical methods should be specific, precise and accurate. In an ideal world, they can identify the compounds and their concentrations in a cannabis product. Analytics are a pillar of their own due simply to the efforts required to ensure the quality and reliability of results provided as well as ongoing optimization of methods to provide more sensitive and useful results. That said, analytics are only truly harnessed when paired with the other three pillars.

extractiongraphic
Figure 1: When harnessed together the pillars of cannabis processing provide platforms of research and investigation that drive the development of world class products.

Biochemistry can be split into two primary focuses. Plant biochemistry focuses back towards cultivation and enables a cannabis scientist to understand the complicated pathways that give rise to unique ratios of bioactive molecules in the plant. Human biochemistry centers on how those bioactive molecules interact with the human endocannabinoid system, as well as how different routes of administration may affect the pharmacokinetic delivery of those active molecules.

Each of the pillars require technical expertise and resources to build, but once established they can be a source of constant innovation. Fig. 1 above shows how each of these pillars are connected. At the intersection of each pillar, specific technology platforms exist that can effectively drive an innovation and discovery cycle towards the development of ideal products.

For example, at the intersection of analytics and cultivation I can develop raw material specifications. This sorely needed quality measure could ensure consistencies in things like cannabinoid content and terpene profiles, more critically they can ensure that the raw material to be processed is free of contamination. Additionally, analytics can provide feedback as I adjust variables in my extraction process resulting in optimized methods. Without analytics I am forced to use very rudimentary methods, such as mass yield, to monitor my process. Mass alone tells me how much crude oil is extracted, but says nothing about the purity or efficiency of my extraction process. By applying plant biochemistry to my cultivation through the use of analytics I could start hunting for specific phenotypes within cultivars that provide elevated levels of specific cannabinoids like CBC or THCV. Taken further, technologies like tissue culturing could rapidly iterate this hunting process6. Certainly, one of the most compelling aspects of cannabinoid therapeutics is the ability to harness the unique polypharmacology of various cannabis cultivars where multiple bioactive compounds are acting on multiple targets7. To eschew the more traditional “silver bullet” pharmaceutical approach a firm understanding of both human and plant biochemistry tied directly to well characterized and consistently processed extracts is required. When all of these pillars are joined effectively we can fully characterize our unique cannabis raw material with targeted cannabinoid and terpene ratios, optimize an extraction process to ensure no loss of desirable bioactive compounds, compare our extracted product back to its source and ensure we are delivering a safe, consistent, “nature identical” extract to use in products with predictable efficacies.

Using these tools, we can confidently set about the task of processing safe, reliable and well characterized cannabis extracts for the development of world class products.

Automation – Planning is Everything

By Vince Sebald
No Comments
VinceSebald

Automation of processes can provide great benefits including improved quality, improved throughput, more consistency, more available production data, notifications of significant events and reduced costs. However, automation can also be expensive, overwhelm your workforce, cause future integration problems and magnify issues that you are currently experiencing. After all, if a machine can do work 100 times faster than a human, it can also produce problems 100 times faster than a human. Whether it is a benefit or a scourge depends largely on the implementation process.

There are thousands of possible technology solutions for just about any production problem. The trick to getting results that will work for your company is to use good engineering practices starting from the beginning. Good engineering practices are documented in various publications including ISPE Baseline Guides, but there are common threads among all such guides. What will the system be used for and what problem is it intended to solve?

The key is implementing a system that is fit for your intended use. As obvious as it sounds, this is often the most overlooked challenge of the process. In the grand scheme of things, it is a MUCH better proposition to spend more time planning and have a smooth operation than implement a system quickly and fight it because it isn’t a good fit for the intended use. The industry is littered with systems that were prematurely implemented and complicate rather than simplify operations. Planning is cheap, but fixing is expensive.

The most important step to getting an automated system that will work for you is also the first:

Defining “what” you need the system to do: User Requirements

Automation Runaway
Once automation is in place, it can be a boon to production, but don’t let your systems get ahead of your planning! It can be difficult to catch up.

With decades of experience in the automation industry, I have seen systems in many industries and applications and it is universally true that the definition of requirements is key to the success of the automation adventure. To clarify, the user requirements are intended to define “what” the system is required to do, rather than “how” it will do it. This means that persons that may not be familiar with the automation technologies can still be (and usually are) among the most important contributors to the user requirements document. Often, the people most familiar with the task that you wish to automate can contribute the most to the User Requirements document.

Some of the components of a User Requirements document typically include:

  • Purpose: What will the system be used for and what problem is it intended to solve?
  • Users: Who will be the users of the system and what is their relevant experience?
  • Integration: Is the system required to integrate into any existing or anticipated systems?
  • Regulatory Requirements: Is the system required to meet any regulatory requirements?
  • Functions: What is the system required to do? This may include operating ranges, operator interface information, records generation and storage, security, etc.
  • Performance: How many units per hour are required to process?  What percent non-conforming product is acceptable?
  • Environment: What environment is the system required to operate in? Indoor, outdoor, flammable, etc.
  • Documentation: What documentation is required with the system to support ongoing maintenance, calibration, etc.?
  • Warranties/Support: Will you perform work in-house, or will the manufacturer support the system?

The level of detail in the User Requirements should be scaled to the intended use. More critical operations may require more detailed and formal User Requirements. At a minimum, the User Requirements could be a punch list of items, but a detailed User Requirements may fill binders. The important thing is that you have one, and that the stakeholders in the operation have been involved in its production and approval.Once completed, the User Requirements can be a very good document to have for prospective providers of solutions to focus their attention on what is important to you, the customer.

Equally important to the process is the idea of not over-constraining the potential solutions by including “how” the system will meet the requirements within the User Requirements. If it is required to use specific technologies for integration with other existing systems, it is appropriate to include that information in the User Requirements. However, if use of a particular technology (e.g. “wireless”) is not required, the inclusion may unnecessarily eliminate viable design options for systems that may address the requirements.

Once completed, the User Requirements can be a very good document to have for prospective providers of solutions to focus their attention on what is important to you, the customer. This helps to ensure that they focus their efforts in the areas that match your needs and they don’t waste resources (which translate to your costs) in areas that don’t have tangible benefits to you, the customer. It also gives you a great tool to “value engineer”, meaning that you can consider cutting design options that do not support the User Requirements, which can reduce project costs and timelines, keeping things lean and on track.

Further steps in the project are built around the User Requirements including system specifications provided by vendors, testing documentation and the overall turnover package. An appropriately scaled User Requirements document is a low cost, easy way to ensure that your automated system will serve you well for years to come. Alternatively, the lack of a User Requirements document is an all-too-common indicator that there may be challenges ahead including scope creep, missed deadlines and unacceptable long term performance.

HACCP

Hazard Analysis and Critical Control Points (HACCP) for the Cannabis Industry: Part 3

By Kathy Knutson, Ph.D.
2 Comments
HACCP

Parts One and Two in this series have defined Good Manufacturing Practices, introduced Hazard Analysis and Critical Control Points (HACCP) and explained the first HACCP step of hazard analysis. A food safety team will typically work from a flow diagram to identify biological, chemical or physical hazards at each step of processing and packaging. Once the hazard is identified, the severity and probability are debated. Hazards with severe consequences or high probability are carried through the HACCP plan as Critical Control Points (CCPs).

Critical Control Points definedHACCP is a do-it-yourself project.

Where exactly will the hazard be controlled? CCPs are embedded within certain steps in processing and packaging where the parameters, like temperature, must be met to ensure food safety. Failure at a CCP is called a deviation from the HACCP plan. The food safety team identifies where manufacturing problems could occur that would result in a product that could cause illness or injury. Not every step is a CCP! For example, I worked with a client that had several locations for filters of a liquid stream. The filters removed food particles, suspended particulates and potentially metal. We went through a virtual exercise of removing each filter one-by-one and talking through the result on controlling the potential hazard of metal. We agreed that failure of the final filter was the CCP for catching metal, but not the other filters. It was not necessary to label each filter as a CCP, because every CCP requires monitoring and verification.

Identification of a CCP starts more documentation, documentation, documentation.

Do you wish you had more reports to write, more forms to fill out, more data to review? No. Nobody wants more work. When a CCP is identified, there is more work to do. This just makes sense. If a CCP is controlling a hazard, you want to know that the control is working. Before I launch into monitoring, I digress to validation.

CCP validationThis is where someone says, “We have always done it this way, and we have never had a problem.”

You want to know if a critical step will actually control a hazard. Will the mesh of a filter trap metal? Will the baking temperature kill pathogens? Will the level of acid stop the growth of pathogens? The US had a major peanut butter recall by Peanut Corporation of America. There were 714 Salmonella cases (individuals) across 46 states from consumption of the contaminated peanut butter. Imagine raw peanuts going into a roaster, coming out as roasted peanuts and being ground into butter. Despite the quality parameters of the peanut butter being acceptable for color and flavor, the roasting process was not validated, and Salmonella survived. Baking of pies, pasteurization of juice and canning all rely on validated cook processes for time and temperature. Validation is the scientific, technical information proving the CCP will control the hazard. Without validation, your final product may be hazardous, just like the peanut butter. This is where someone says, “We have always done it this way, and we have never had a problem.” Maybe, but you still must prove safety with validation.

The hazard analysis drives your decisions.

Starting with the identification of a hazard that requires a CCP, a company will focus on the control of the hazard. A CCP may have one or more than one parameter for control. Parameters include time, temperature, belt speed, air flow, bed depth, product flow, concentration and pH. That was not an exhaustive list, and your company may have other critical parameters. HACCP is a do-it-yourself project. Every facility is unique to its employees, equipment, ingredients and final product. The food safety team must digest all the variables related to food safety and write a HACCP plan that will control all the hazards and make a safe product.

Meeting critical limits at CCPs ensures food safety

The HACCP plan details the parameters and values required for food safety at each CCP.The HACCP plan identifies the minimum or maximum value for each parameter required for food safety. A value is just a number. Imagine a dreadful day; there are problems in production. Maybe equipment stalls and product sits. Maybe the electricity flickers and oven temperature drops. Maybe a culture in fermentation isn’t active. Poop happens. What are the values that are absolutely required for the product to be safe? They are often called critical limits. This is the difference between destroying product and selling product. The HACCP plan details the parameters and values required for food safety at each CCP. In production, the operating limits may be different based on quality characteristics or equipment performance, but the product will be safe when critical limits are met. How do you know critical limits are met?

CCPs must be monitored

Every CCP is monitored. Common tools for monitoring are thermometers, timers, flow rate meters, pH probes, and measuring of concentration. Most quality managers want production line monitoring to be automated and continuous. If samples are taken and measured at some frequency, technicians must be trained on the sampling technique, frequency, procedure for measurement and recording of data. The values from monitoring will be compared to critical limits. If the value does not reach the critical limit, the process is out of control and food safety may be compromised. The line operator or technician should be trained to know if the line can be stopped and how to segregate product under question. Depending on the hazard, the product will be evaluated for safety, rerun, released or disposed. When the process is out of control, it is called a deviation from the HACCP plan.

A deviation initiates corrective action and documentation associated with the deviation. You can google examples of corrective action forms; there is no one form required. Basically, the line operator, technician or supervisor starts the paperwork by recording everything about the deviation, evaluation of the product, fate of the product, root cause investigation, and what was done to ensure the problem will not happen again. A supervisor or manager reviews and signs off on the corrective action. The corrective action form and associated documentation should be signed off before the product is released. Sign off is an example of verification. Verification will be discussed in more detail in a future article.

A More Effective and Efficient Approach to Purer Cannabidiol Production Using Centrifugal Partition Chromatography

By Lauren Pahnke
3 Comments

Many physicians today treat their patients with cannabidiol (CBD, Figure 1), a cannabinoid found in cannabis. CBD is more efficacious over traditional medications, and unlike delta-9 tetrahydrocannbinol (THC), the main psychoactive compound in cannabis, CBD has no psychoactive effects. Researchers have found CBD to be an effective treatment for conditions such as cancer pain, spasticity in multiple sclerosis, and Dravet Syndrome, a form of epilepsy.

CBD is still considered an unsafe drug under federal law, but to meet the medical demand, 17 states in the US recently passed laws allowing individuals to consume CBD for medical purposes. A recent survey found that half of medicinal CBD users rely on the substance by itself for treatment. As doctors start using CBD to treat more patients, the demand for CBD is only expected to rise, and meeting that demand can pose challenges for manufacturers who are not used to producing such high quantities of CBD. Furthermore, as CBD-based drugs become more popular, the US Food and Drug Administration (FDA) will likely require manufacturers to demonstrate they can produce pure, high-quality products.

Most manufacturers use chromatography techniques such as high performance liquid chromatography (HPLC) or flash chromatography to isolate compounds from natural product extracts. While these methods are effective for other applications, they are not, however, ideal for CBD isolate production. Crude cannabis oil contains some 400 potentially active compounds and requires pre-treatment prior to traditional chromatography purification. Both HPLC and flash chromatography also require silica resin, an expensive consumable that must be replaced once it is contaminated due to irreversible absorption of compounds from the cannabis extract. All of these factors limit the production capacity for CBD manufacturers.

Additionally, these chromatography methods use large quantities of solvents to elute natural compounds, which negatively impacts the environment.

A Superior Chromatography Method

Centrifugal partition chromatography (CPC) is an alternative chromatography method that can help commercial CBD manufacturers produce greater quantities of pure CBD more quickly and cleanly, using fewer materials and generating less toxic waste. CPC is a highly scalable CBD production process that is environmentally and economically sustainable.

The mechanics of a CPC run are analogous to the mechanics of a standard elution using a traditional chromatography column. While HPLC, for instance, involves eluting cannabis oil through a resin-packed chromatography column, CPC instead elutes the oil through a series of cells embedded into a stack of rotating disks. These cells contain a liquid stationary phase composed of a commonly used fluid such as water, methanol, or heptane, which is held in place by a centrifugal force. A liquid mobile phase migrates from cell to cell as the stacked disks spin. Compounds with greater affinity to the mobile phase are not retained by the stationary phase and pass through the column faster, whereas compounds with a greater affinity to the stationary phase are retained and pass through the column slower, thereby distributing themselves in separate cells (Figure 2).

Figure 2- CPC
Figure 2. How CPC isolates compounds from complex, natural mixtures. As the column spins, the mobile phase (yellow) moves through each cell in series. The compounds in the mobile phase (A, B, and C) diffuse into the stationary phase (blue) at different rates according to their relative affinities for the two phases.

A chemist can choose a biphasic solvent system that will optimize the separation of a target compound such as CBD to extract relatively pure CBD from a cannabis extract in one step. In one small-scale study, researchers injected five grams of crude cannabis oil low in CBD content into a CPC system and obtained 205 milligrams of over 95% pure CBD in 10 minutes.

Using a liquid stationary phase instead of silica imbues CPC with several time and cost benefits. Because natural products such as raw cannabis extract adhere to silica, traditional chromatography columns must be replaced every few weeks. On the other hand, a chemist can simply rinse out the columns in CPC and reuse them. Also, unlike silica columns, liquid solvents such as heptane used in CPC methods can be distilled with a rotary evaporator and recycled, reducing costs.

Environmental Advantages of CPC

The solvents used in chromatography, such as methanol and acetonitrile, are toxic to both humans and the environment. Many environmentally-conscious companies have attempted to replace these toxic solvents with greener alternatives, but these may come with drawbacks. The standard, toxic solvents are so common because they are integral for optimizing purity. Replacing a solvent with an alternative could, therefore, diminish purity and yield. Consequently, a chemist may need to perform additional steps to achieve the same quality and quantity achievable with a toxic solvent. This produces more waste, offsetting the original intent of using the green solvent.

CPC uses the same solvents as traditional chromatography, but it uses them in smaller quantities. Furthermore, as previously mentioned, these solvents can be reused. Hence, the method is effective, more environmentally-friendly, andeconomically feasible.

CPC’s Value in CBD Production

As manufacturers seek to produce larger quantities of pure CBD to meet the demand of patients and physicians, they will need to integrate CPC into their purification workflows. Since CPC produces a relativelyduct on a larger scale, it is equipped to handle the high-volume needs of a large manufacturer. Additionally, because it extracts more CBD from a given volume of raw cannabis extract, and does not use costly silica or require multiple replacement columns, CPC also makes the process of industrial-scale CBD production economically sustainable. Since it also uses significantly less solvent than traditional chromatography, CPC makes it financially feasible to make the process of producing CBD more environmentally-friendly.

Pennsylvania Adjusts Medical Cannabis Program

By Aaron G. Biros

On Monday, Pennsylvania Health Secretary Dr. Rachel Levine announced plans to allow patients access to whole plant, dried flower, as well as more qualifying conditions. The move reverses the previous rule permitting dispensaries to sell only processed forms of cannabis, which some say limited access and kept costs high for patients.

According to the Marijuana Policy Project (MPP), the Department of Health approved changes to the program at a hearing on Monday, which were recommended by the Advisory Board last week. While smoking remains theoretically prohibited, patients can now access the flower for vaporization.

The medical cannabis program in Pennsylvania has only been functional for a few months now; patients began getting access to the drug back in February of 2018. In a press release, MPP says only a small number of cultivators and dispensaries are currently operating. This fact, coupled with the need to purchase processed forms of cannabis, has created product shortages and costly medicine for patients.

It is expected that this move could help alleviate some of those problems in the state’s new program. “Allowing cannabis in its natural, flower form and expanding the list of qualifying conditions will have a huge positive impact on seriously ill Pennsylvanians,” says Becky Dansky, legislative counsel for the Marijuana Policy Project, who helped lead the legalization effort in Pennsylvania’s legislature. “By being able to provide medical marijuana in plant form, producers will be able to get medicine into the hands of patients much more quickly and for much lower cost to patients,” says Dansky. “This is vitally important for patient access right now while the program is still getting off the ground and production is not yet at full capacity. We hope these rules are promulgated as quickly as possible so even more patients will be able to find relief.”

The qualifying conditions added to the list for patients seeking medical cannabis is set to include cancer remission therapy as well as opioid-addiction therapy, which are two very notable additions. With more qualifying conditions and a potentially cheaper form of medicine, these changes could improve the program’s efficacy in treating patients.

HACCP

Hazard Analysis and Critical Control Points (HACCP) for the Cannabis Industry: Part 2

By Kathy Knutson, Ph.D.

HACCP

HACCP is a food safety program developed in the 1960s for the food manufacturing industry, mandated for meat, seafood and juice and adopted by foodservice for the safe serving of meals at restaurants. With state requirements for the safe production of cannabis-infused products, namely edibles, facilities may be inspected against HACCP principles. The cannabis industry and state inspectors recognize the need for safe edible manufacture. Lessons can be learned from the food industry, which has advanced beyond HACCP plans to food safety plans, starting with procurement and including the shipment of finished product to customers.

In my work with the food industry, I write HACCP and food safety plans and deliver training on food safety. In Part 1 of this series, I wrote about the identification of hazards, which is the first step in HACCP plan development. Before we continue with the next HACCP step, I will discuss Good Manufacturing Practices (GMPs). GMPs are the foundation on which HACCP is built. In other words, without GMPs in place, the facility will not have a successful HACCP program. GMPs are required in the food, dietary supplement and pharmaceutical industries, all under the enforcement of the federal Food and Drug Administration (FDA). Without federal regulation for cannabis edible manufacture, there may not be state-mandated requirements for GMPs. Let me warn you that any food safety program will not succeed without proper control of GMPs.HACCP

GMPs cover all of your programs and procedures to support food safety without having a direct, instant control. For example, when brownies are baked as edibles, food safety is controlled by the time and temperature of baking. A written recipe and baking procedure are followed for the edible. The time and temperature can be recorded to provide documentation of proper baking. In the food industry, this is called a process preventative control, which is critical to food safety and is part of a HACCP plan. Failure of proper time and temperature of baking not only leads to an unacceptable product in terms of quality, but results in an unsafe product that should not be sold.

Back to GMPs. Now think of everything that was done up to the steps of mixing and baking. Let’s start with personnel. Facilities for edibles have hiring practices. Once an employee is hired, the employee is trained, and training will include food safety procedures. When working at the job after training, the employee measuring ingredients will demonstrate proper grooming and hand washing. Clean aprons, hairnets, beard nets and gloves will be provided by the facility and worn by the employee. The same goes for the employee that bakes and the employee that packages the edible. One category of GMPs is Personnel.

Edibles facilities are not foodservice; they are manufacturing. A second GMP category is cleaning and sanitizing. Food safety is controlled through proper cleaning and sanitizing of food contact surfaces (FCS). The edible facility will have in place the frequency and methods for cleaning all parts of the facility- outside, offices, restrooms, break room and others. GMPs cover the general cleaning procedures and procedures for cleaning receiving, storage; what we would consider processing to include weighing, process steps and packaging; finished product storage and shipping. Management of the facility decides the methods and frequency of cleaning and sanitizing with greater care given to processing. Without proper cleaning and sanitizing, a facility cannot achieve food safety.

I could go on and on about GMPs. Other GMPs include water safety, integrity of the buildings, pest control program, procurement, sewage disposal and waste disposal. Let’s transition back to HACCP. In Part 1 of this series, I explained identification of hazards. Hazards are one of three types: biological, chemical and physical.

At this point, I am not surprised if you are overwhelmed. After reading Part 1 of this series, did you form a food safety team? At each edibles facility, there should be at least one employee who is trained externally in food safety to the standard that foodservice meets. Classes are offered locally and frequently. When the facility is ready, the next step of training is a HACCP workshop for the food industry, not foodservice. Edibles facilities are not foodservice; they are manufacturing. Many colleges and associations provide HACCP training. Finally, at the least, one employee should attend a workshop for Preventive Controls Qualified Individual.

To institute proper GMPs, go to ConnectFood.com for a GMP checklist. Did you draw up a flow diagram after reading Part 1? With a flow diagram that starts at Receiving and ends at Shipping, the software at ConnectFood.com takes you through the writing steps of a HACCP or food safety plan. There are many resources out there for GMPs, so it can get overwhelming. ConnectFood.com is my favorite resource.

The next step in HACCP development after identification of hazards is to identify the exact step where the hazard will be controlled. Strictly speaking, HACCP only covers process preventive controls, which typically start with a weigh step and end with a packaging step. A facility may also have a step where temperature must be controlled for food safety, e.g. cooling. In HACCP, there are commonly two process preventive controls:

  • Biological hazard of Salmonella and Escherichia coli: the heat step
  • Physical hazard of metal: metal detector

Strictly speaking, HACCP does not include cleaning, sanitizing and supplier approval for procurement of ingredients and packaging. I hope you see that HACCP is not enough. There have been hundreds of recalls and outbreaks due to problems in non-processing steps. The FDA requires food manufactures to go beyond HACCP and follow a written food safety plan, which includes hazards controlled at these steps:

  • Biological hazard of Listeria monocytogenes: cleaning and sanitizing of the processing environment and equipment
  • Physical hazards coming in with ingredients: supplier approval
  • Physical hazard of glass and hard plastic: Here I am thinking of glass breaking or plastic pieces flying off buckets. This is an internal hazard and is controlled by following written procedures. The written document is a Standard Operating Procedure (SOP).
  • Chemical hazard of pesticides: supplier approval
  • Chemical hazard of mycotoxins: supplier approval
  • Chemical hazard of allergens: supplier approval, label check at Receiving and product labeling step

Does a cannabis edible facility honestly not care or not control for pesticides in ingredients because this is not part of HACCP? No. There are two ways for procurement of ingredients in which pesticides are controlled. Either the cannabis cultivation is controlled as part of the samebusiness or the facility works with a supplier to confirm the ingredient meets pesticide tolerances. Strictly speaking, this control is not part of HACCP. For this and many other reasons, HACCP is a good place to start the control of food safety when built on a solid foundation of GMPs. In the same way the food industry is required to go beyond HACCP with a food safety plan, the cannabis industry must go beyond HACCP.
