Massachusetts Regulators Crack Down On Pesticide Use

By Aaron G. Biros

Earlier this month, the Massachusetts Department of Health sent a cease-and-desist letter to Good Chemistry, a Colorado-based brand operating in Massachusetts with a dispensary in Worcester and a cultivation facility in Bellingham. The letter claimed Good Chemistry used unapproved pesticides and must close their operations in the state.

According to a Boston Globe article, the company used three pesticides (approved for use on organic food products by the federal government) that cannabis regulators in Nevada, Oregon, Washington and Colorado have all approved for use in cannabis cultivation. Previously, Massachusetts has allowed a number of pesticides to be used on cannabis, but since last year when the state’s Department of Agricultural Resources took over regulating pesticide use on cannabis, they decided to ban all pesticides.

Representatives from Good Chemistry insist the compounds used were safe and that the state is singling them out when the practice is widespread in the industry. “These organic compounds are safe all over the country, and they’re safe in Massachusetts,” Jim Smith, a lawyer for Good Chemistry, tells the Boston Globe. “For the state to single out Good Chemistry for using an industry-standard practice is absolutely wrong. It’s not acceptable — and we’re not going to destroy the crop, because it poses no risk to public safety whatsoever.”

Good Chemistry even disclosed to the state that they would use those pesticides when they applied for a cannabis business license. According to Telegram.com, a local Worcester publication, Matthew Huron, chief executive officer of Good Chemistry, is asking the state to reverse their decision. “The Department of Public Health has the discretion to amend or rescind their order to allow us to make the cannabis we’ve cultivated available to patients in the Worcester community,” says Huron. “Patients have let us know that they really benefited from Good Chemistry’s wide selection of high quality cannabis strains, and they would like access to it again as soon as possible. We’ve asked the state to incorporate the research, analysis and experience that led other states like Colorado, Nevada, Washington and Oregon to determine that the use of these cultivation methods are best practices and helps create healthier, contaminant-free cannabis for patients and the industry as a whole.”

On September 5, the Department of Public Health allowed Good Chemistry to amend the cease-and-desist so they could sell products from other producers in the state. “Many of our patients rely on our medicine we grow specifically and we now are only allowed to sell third party product,” Huron told Telegram.com.

Last week, the American Association for Laboratory Accreditation (A2LA) and the American Trade Association for Cannabis and Hemp (ATACH) announced a new partnership agreement. This partnership is the first of its kind where a laboratory accreditation body and a cannabis trade organization work together under an MOU.

According to the press release, the two organizations hope to promote “foundational standards for quality control testing and regulatory guidelines that promote product safety.” Both organizations will advocate for the adoption of industry standards they deem appropriate for recreational and medical cannabis as well as hemp testing in the United States.

Michael Bronstein, executive director of ATACH, says there is an urgent need for open-source consensus standards and standard test methods for cannabis testing. “In an industry that lacks standard test methods and where testing is such a crucial part of the regulatory landscape, the need for open-source consensus standards is especially significant,” says Bronstein. “The development and adoption of standard test methods for cannabis testing is essential in ensuring consistency between laboratories, encouraging uniformity in state testing regulation, and providing a safe and consistent product to consumers.”

The press release also states that A2LA and ATACH seek to “develop regulation and adopt industry standards with goals of advancing and professionalizing the industry.”

Voelkner says they’ve been working with clients at cannabis labs over the past few years to configure their LIMS for this space specifically. “The lab managers can modify workflows on their own without having to write code,” says Voelkner. “We have a well-established solution with a good track record, that’s been around for a while and is proven. Some other players that are brand new to the space may be new to LIMS and that may not be a good thing. We are a market leader in the global LIMS space with a proven product that is very well established and very powerful.” Voelkner adds that lab managers get to own their data, not LabVantage. “You own the data. It is your database and it is proprietary to you. It is yours to use as you see fit.”

Lab managers have the option to configure the system to adapt to new compliance issues themselves, or work with the LabVantage professional services team to build it out further. “This particular space is new and emerging, it is pretty dynamic — we see a lot of change happening,” says Voelkner. “We believe this space needs a highly flexible platform and this is a proven technology solution with a lot of configurability built into it.”

How to Vet Suppliers in Cannabis Product Manufacturing

By Amy Davison
1 Comment

The quality of your edible cannabis product can only be as reliable as the components that comprise it. The three types of components include active ingredients (such as CBD oil), packaging components  (such as the bottles that hold finished product) and inactive ingredients (such as coconut oil). When evaluating a potential supplier for these three areas, a risk-based method follows a vendor selection process that highlights critical ingredients and also adequately assesses excipients. With this approach, the vetting process for a supplier is based on the impact the potential ingredient or component will have on the quality and purity of the finished product.

Choose only those suppliers who can provide certification that the packaging components are food-grade or food-safeThere are three basic categories to guide vendor assessment. Is the supplier providing 1) a packaging component with product contact, 2) an excipient, or inactive ingredient, or 3) the active ingredient? Regardless of the category, due to the factious nature of cannabis, it is important to first verify with a vendor that it will sell its products to a company in the cannabis industry. Once that is determined, the evaluation process may begin.

Packaging Components

Sourcing validation is a critical initial step in the production process. (image credit: Lucy Beaugard)

Packaging components, such as bottles and caps, are considered primary packaging because they have direct contact with the finished product. Suppliers of the primary packaging must be able to provide assurance that their goods do not contain additives that are harmful to consumers. Therefore, choose only those suppliers who can provide certification that the packaging components are food-grade or food-safe. Reputable vendors will also be able to provide a certificate of compliance, also known as a certificate of conformance, which states that the component meets specifications required for that part. Many cannabis regulations require finished products to be sold in child-resistant packaging, so the supplier will need to provide child-resistant certification for the packaging components, if applicable.

Excipients

Excipients are ingredients that are added to a product for the purposes of streamlining the manufacturing process and enhancing physical characteristics such as taste and color. Some examples could include coconut oil, starch and alcohol. Though they do not have the same critical nature as active ingredients, their potential risk to a finished product is generally greater than that of a packaging component. As such, there are additional factors to consider for an excipient vendor. Verify with the supplier that it can provide the following documentation. While governing regulations may not require some information, the data included in these documents are important to ensure the quality of your finished product.

  • Certificate of Analysis (or, certificate of conformance), for each lot of material. The information on a certificate, including the tests performed, specifications and test results must be sufficient to determine if the material is acceptable for use in the product.
  • Allergen Statement. This statement is important to accurately include or disclaim allergens on the finished product label.
  • Residual Solvent Statement. Solvents are commonly used to bolster the manufacturing process for a material. In order to maintain acceptable levels of residual solvents in a final product, it is necessary to also consider the toxicity and level of each solvent in the raw material.
  • Heavy Metals Certification. Since metals pose a risk to consumer safety, it is important to know what amounts, if any, are being contributed to your product by raw materials.

Because changes in an excipient can impact your finished product, make every attempt to obtain a commitment from a supplier to notify you if changes are made to the excipient’s specifications.

Active Ingredients

Cannabis oil is the ingredient that, when the edible cannabis product is consumed, is biologically “active.” Thus, it is considered to be the active ingredient in cannabis products. Since cannabis oil has a direct impact on the quality of a product, it is critical that the oil supplier be appropriately evaluated. One of the main considerations for a cannabis oil supplier is whether the supplier is willing to host initial and periodic audits of its manufacturing facility. Such audits are crucial in assessing the capability of the vendor to comply with regulatory requirements and established procedures – can the supplier consistently provide quality material? The answer to this question is too important to risk for you and your customers.As anyone working in the industry has experienced, anything related to cannabis is placed under an unprecedented critical lens.

Additionally, verify the oil supplier will provide key documentation, such as that listed above for excipients, to support the quality and purity of the oil. And last but not least, ensure the information reported by the supplier is adequate to meet the requirements of your finished product.

Evaluation guidelines and criteria such as these should be added to standard operating procedures to ensure consistency and quality across all products. As anyone working in the industry has experienced, anything related to cannabis is placed under an unprecedented critical lens. The importance of consumer safety and bolstering industry integrity is paramount. Sourcing validation is a critical initial step in the production process that can directly impact a company’s success and longevity in the cannabis industry.

Basic Training for Employers and Employees in the Cannabis Industry

Basic Training for Employers and Employees in the Cannabis Industry

Basic Training for Employers and Employees in the Cannabis Industry

The cannabis industry is evolving as more states begin to legalize; as the legalization of cannabis grows, the industry will need more well-informed dispensaries and dispensary employees.

Unfortunately, there are employees in dispensaries without proper training and some are put in positions to recommend specific strains to patients that may not be accurate. Getting proper training is important, no matter which cannabis job you want to pursue.

More Training Is Needed

Currently, there are no national standards for training dispensary employees, there is not even a licensing code. Therefore, it is important for owners to investigate state laws and understand legal minimums for worker education.

There are states, like Massachusetts, which requires a $500 fee for employee registration. There are other states that require cannabis employees receive a certain number of education hours on specific topics, like patient confidentiality.

Overall, more than fifty percent of cannabis dispensary staff has reported receiving some type of formal training and only twenty percent of staff members have received medical cannabis training.Basic Training for Employers and Employees in the Cannabis Industry

Dispensary staff should receive training on how and when to make appropriate suggestions to patients. Any successful dispensary owner will acknowledge that employee education pays off in reduced loss, increased sales and avoided fines. There are more benefits to employee training than just these and there are steps owners can take to ensure they are getting the most out of their business and employees.

Setting up a System

When a dispensary has protocols in place that show how the business operates, the company will have consistency and organization. No matter the task, all team members must follow specific procedural protocols.

Mostly, mistakes are made when steps are missed or misunderstood by new employees, but with proper and thorough training, this can be avoided. Owners should be investing in a POS software system that is straightforward; this will reduce training time and make it easier for new staff to be familiar with the system.Having budtenders that can educate and connect with the customers on a personal level is invaluable

Teaching budtenders to adopt a soft sell technique will be the most effective when it comes to increasing sales. Many customers seeking relief using cannabis are not going to respond to a hard sell technique, as this comes off pushy or aggressive.

There are going to be customers who are unsure of what products they want; theses customers will need guidance, and training employees to make suggestions based on what the customer is looking for is the best sales practice.

Having budtenders that can educate and connect with the customers on a personal level is invaluable; dispensaries that do this will have repeat customers.

More States Legalizing, More Dispensaries and More Employees

As the United States heads towards cannabis legalization, slowly but surely, we need to be prepared to train workers. When you have a dispensary that you have already spent millions of dollars on the application process, you don’t have time to be messing around with employees that are not serious.

There are many different options anyone in the cannabis industry can seek out to educate themselves more in the business.Those distributing cannabis must take their duties as seriously as pharmaceutical technicians, because in a sense that is what they are doing. They are giving information on the prescription or drug to a customer that is using it for an intended a purpose.

Cannabis users come in many different ages and aliments. It is important for budtenders and dispensary owners to understand the backgrounds of each customer to increase their up-sale potential.

While compassion isn’t something you can learn online or in a classroom, it is always a good idea to remind others to be compassionate. The budtender that asks the right questions, takes time with each patient to care for them and goes over practical products for the client will be the budtender with the most sales revenue.

Higher Learning

There are many different options anyone in the cannabis industry can seek out to educate themselves more in the business.

Some platforms are available online and are filled with important content that can teach you about different aspects of the cannabis plant and industry. These classes can prepare employees or owners for success.The most important training will be the training of patients

There are courses that can educate you in how to cook and healing with cannabis. You can also learn about laws on a state-by-state basis when you are enrolled in a cannabis-training program. The cannabis industry is large and growing; entrepreneurs, lawyers and caregivers can learn about the growing movement and expand their knowledge on this topic.

Patient Training

The most important training will be the training of patients, who will be navigating between the world of western medication and the new option of medicinal cannabis.

There are obviously many positive things that will come from the legalization of cannabis, one of the biggest being more options for pain management patients. There is a misconception that people are using medicinal cannabis as an excuse to get high; however, many patients in most states are over the age of 50.

In 2016, it was estimated that 650,000 Americans were using cannabis in compliance with the laws of their state. As legalization grows to a national level, we are going to need to be educating patients.

It is important for citizens to talk to their doctors about methods they believe will work best for them. It is necessary to communicate strains that are ineffective or unsatisfying. Keeping a cannabis journal is a good way to know what dose and strain you benefit from the most.

There are many ways patients can be educated in the cannabis industry, and dispensaries that encourage patient education will grow customer loyalty. The person who knows the facts and is confident in their information will be more successful than the person who guesses.

Be sure you, your staff and your customers know the laws, strains and can accurately answer questions about cannabis.

Distillation Of Your Cannabis Extract: Ignorance Is Not Bliss

By Dr. Edward F. Askew

Dr. Ed Askew

In a previous article I discussed the elephant in the room for clients of laboratory services- the possibility of errors, inaccurate testing and dishonesty.

Now, I will explain how the current “smoke and mirrors” of distillation claims are impacting the cannabis industry in the recreational and medical areas. We have all heard the saying, “ignorance is bliss.” But, the ignorance of how distillation really works is creating misinformation and misleading consumers.

That is, just because a cannabis extract has been distilled, doesn’t mean it is safer.There have been reports of people claiming that “Distilled cannabis productsthat are Category 2 distillate are pesticide free and phosphate free, while Category 1 has pesticides and phosphates, but within acceptable limits”

The problem is that these claims of Category 1 and Category 2 cannot be proven just by saying they are distilled. Ignorance of the physical chemistry rules of distillation will lead to increased concentrations of pesticides and other organic contaminants in the supposedly purified cannabis distillate. That is, just because a cannabis extract has been distilled, doesn’t mean it is safer.

So, let’s look at a basic physical chemistry explanation of the cannabis distillation process.

  • First off, you must have an extract to distill. This extract is produced by butane, carbon dioxide or ethanol extraction of cannabis botanical raw material. This extract is a tarry or waxy solid. It contains cannabinoids, terpenes and other botanical chemicals. It will also contain pesticides, organic chemicals and inorganic chemicals present in the raw material. The extraction process will concentrate all of these chemical compounds in the final extract.
  • Now you are ready to distill the extract. The extract is transferred to the vacuum distillation vessel. Vacuum distillation is typically used so as to prevent the decomposition of the cannabinoid products by thermal reactions or oxidation. Under a vacuum, the cannabinoids turn into a vapor at a lower temperature and oxygen is limited.
  • Part of the vacuum distillation apparatus is the distillation column. The dimensions of this column (length and width) along with the packing or design (theoretical plates) will determine the efficiency of distillation separation of each chemical compound. What this means is that the more theoretical plates in a column, the purer the chemical compound in the distillate. (e.g. Vigreux column = 2-5 theoretical plates, Oldershaw column = 10-15 plates, Sieve plate column = any number you can pay for).
  • The temperature and vacuum controls must be adjustable and accurate for all parts of the distillation apparatus. Failure to control the temperature and vacuum on any part to the apparatus will lead to:
    • Thermal destruction of the distillate
    • Oxidation of the distillate
    • Impure distillate

Now, you can see that a proper distillation apparatus is not something you throw together from a high school chemistry lab. But just having the proper equipment will not produce a pure cannabis product. The physical chemistry that takes place in any distillation is the percentage a chemical compound that occurs in the vapor phase compared to the percentage in liquid phase.So, how can you produce a cannabis distillate that is clean and pure?

For example, let’s look at whiskey distillation. In a simple pot still, alcohol is distilled over with some water to produce a mixture that is 25%-30% ethanol. Transferring this distillate to an additional series of pot stills concentrates this alcohol solution to a higher concentration of 85%-90% ethanol. So, each pot still is like a single theoretical plate in a distillation column.

But, if there are any chemical compounds that are soluble in the vapor produced, they will also be carried over with the vapor during distillation. This means that pesticides or other contaminants that are present in the cannabis extract can be carried over during distillation!

So, how can you produce a cannabis distillate that is clean and pure?

  • Produce a cannabis extract that has lower concentrations of bad chemicals. Since a lot of the cannabis extracts available for distillation are coming from grey-black market cannabis, the chances of contamination are high. So, the first thing to do is to set up an extraction cleanup procedure.
    • An example of this is to wash the raw extract to remove inorganic phosphates. Then recrystallize the washed extract to remove some of the pesticides.
  • Make sure that the distillation apparatus is set up to have proper temperature and vacuum controls. This will limit production of cannabis decomposition products in the final distillate.
  • Make sure your distillation apparatus has more than enough theoretical plates. This will make sure that your cannabis distillate has the purity needed.
  • Finally, make sure that the staff that operates the cannabis distillation processes are well trained and have the experience and knowledge to understand their work.

Inexperienced or under-trained individuals will produce inferior and contaminated product. Additional information of extract cleanup and effective vacuum distillation can be obtained by contacting the author.

Quality Plans for Lab Services: Managing Risks as a Grower, Processor or Dispensary, Part 5

Protection in the Court of Public Opinion

In the last four articles, I have outlined areas that impact your operations as they apply to laboratory quality programs. But this article will take a different path. It will focus on protecting your crop and brand along with any business that utilizes your crop, such as dispensaries or edible manufactures in the court of public opinion.

Now, the elephant in the room for cannabis companies is the difference between rules written by the state and their enforcement by the state. There are many anecdotal stories out there that can be used as case studies in identifying ways to protect your brand. Remember, consumers and the media caught them, not the regulators.

Cheating in the cannabis industry: growers, dispensaries, edibles manufactures, etc. This includes:

  1. Finding laboratories that will produce results that the client wants (higher potency numbers)
  2. Not testing for a particular contaminant that may be present in the cannabis product.
  3. Selling failed crops on the gray or black market.
  4. Claiming to regulators that the state rules are unclear and cannot be followed (e.g. So, give me another chance, officer)

So why should you be worried? Because, even if the state where you operate fails to enforce its own rules, the final end-user of your product will hold you accountable! If you produce any cannabis product and fail to consider these end-users, you will be found out in the court of public opinion by either the media or by the even more effective word of mouth (e.g. Social Media).

So, let’s take a look at some recent examples of these problems:

  1. “Fungus In Medical Marijuana Eyed As Possible Cause In California Man’s Death”
  2. “Pesticides and Pot: What’s California Smoking?”
  3. Buyers beware: California cannabis sold Jan. 1 could be tainted”

Each of these reports lists contamination by microbial stains or pesticides as being rampant within the California market whose products are used for medical or recreational use. Just imagine the monetary losses these cannabis businesses faced for their recalled cannabis product when they got caught. Remember, consumers and the media caught them, not the regulators.Institute a quality program in your business immediately.

How can you be caught? There are many different ways:

  1. Consumer complaints to the media
  2. Secret shopper campaigns (more to come on that in the next article)
  3. Media investigations
  4. Social media campaigns

What are the effects on your business? Product recalls such as these two to hit the California market recently.

So, what should you do to produce an acceptable product and provide reasonable protection to your cannabis business? Institute a quality program in your business immediately. This quality program will include areas of quality assurance and quality control for at least these areas.

  1. Growing
  2. Processing or formulating
  3. Shipping
  4. Dispensing
  5. Security
  6. Training of staff
  7. Laboratory services

Setting up and supporting these programs requires that your upper management impose both a rigorous training program and make employee compliance mandatory. Otherwise, your business will have an unreasonable risk of failure in the future.

Further information on preparing and instituting these types of quality assurance and quality control programs within your business can be found at the author’s website.

  • Tim Lombardo and Marielle Weintraub, both from Covance Food Solutions, will identify common pathogens and areas where cross contamination can occur for edibles manufacturers.

The Food Safety Consortium will be held November 13–15 in Schaumburg, Illinois (just outside of Chicago). To see the full list of presenters and register for the conference, go the Food Safety Consortium’s website.

Safety & Efficacy: Ensuring Dosing Accuracy for Infused Products

By Amy Davison

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.

Two Recalls Hit California Cannabis Market

By Aaron G. Biros
No Comments

Just weeks ago, the first voluntary cannabis product recall occurred under California’s new regulations. According to an article on MJBizDaily.com by John Schroyer, the recall for their vaporizer cartridges affects almost 100 dispensaries in California.

Bloom Brands, the company issuing the voluntary recall, mentioned in a press release that batches sold between July 1-19, 2018 were contaminated with the pesticide Myclobutanil and therefore does not meet the Bureau of Cannabis Control (BCC) standards. Below is an excerpt from the press release:

We are working closely with the BCC to remedy this issue and expect clean, compliant products to be back on shelves in three weeks…. At Bloom, we are continuing to work with the BCC and other partners to ensure that the space is properly regulated and safe for all customers. Transparency and safety remain our top concerns and we will provide updates as additional information becomes available. We apologize for any concern or inconvenience this serious misstep has caused. We thank you for your continued trust and confidence in our products.

Then, just days later, Lowell Herb Co. issued a voluntary recall on their pre-rolls. First reported by MJBizDaily.com, it appears the products initially passed multiple lab tests and was cleared for retail sales. Weeks after the batch passed tests, a laboratory reversed its decision, saying the products failed to pass the state’s testing standards. The contaminant in question was not mentioned.

The CCIA post calling out the BCC
The CCIA post calling out the BCC

Many seem to think these recalls are a product of the BCC’s unrealistic expectations in their lab testing rules. In a Facebook post days ago, the California Cannabis Industry Association called out the BCC for their unworkable rules. “The BCC has set testing standards that are nearly impossible to meet,” reads the post. “As a result recalls like this will be the norm and the industry will suffer a bottleneck in supply. Testing standards need to be realistic, not impossible.”

On July 13, California issued the first draft of their proposed permanent regulations, which would update and change the current emergency regulations. The proposed action levels for a batch to pass a pesticide test can be found on pages 105 and 106.
