Twelve Tips for Scaling Your Cannabis Business

We know a thing or two about scaling a cannabis business. While we don’t own a plant-touching business ourselves, we have helped companies like Tokyo Smoke, Superette and Northern Helm to open dozens of dispensaries in less than 3 years as their IT company. Here are some of the things we’ve learned along the way.

Find reliable partners

You can’t do it all alone. Especially when you’re trying to grow fast in a new industry like cannabis. Find reliable external partners you can depend on in areas like construction, design, staffing, financing, legal, real estate, accounting, HR, IT and security. If you’re just starting, consider dividing the work between competing firms, then committing to the one that performs the best.

Maintain consistency

You don’t want to reinvent the wheel with every new location. Develop standardized processes, procedures and equipment as early as possible. This is critical for aspects of your business like efficiency, profit margins and brand awareness.

We work with our clients to develop a standard IT stack (all the same hardware, software and configurations). This makes setups quicker and cross-location management easier and can make you eligible for bulk purchasing discounts.

At the same time, if any of them don’t work out, switch them out as soon as possible. Don’t compound the error by sticking with what isn’t working.

Develop standardized processes, procedures and equipment as early as possible.

Also don’t be afraid to try new things here and there or make each location unique in more subtle ways. Our clients at Superette are a great example of keeping their brand consistent enough across their locations that you know it’s a Superette store just by looking at it; at the same time each store is just a little bit different so that each location is a unique experience.

Leverage multi-site tech

Most cannabis software is web-based and lets you manage multiple different locations in a single platform. Make sure to make good use of this and not use different software for different locations.

This goes for a lot of non-cannabis-specific software too, like Sage, Office 365, Google Workspaces and Solink (a platform that lets you manage all your surveillance systems in one dashboard, and integrates with your POS or ERP).

Use compliance and licensing software

Cannabis regulations can vary widely not only state by state but city by city. Keeping up with all these regulations can be difficult even if you already have a legal expert to rely on.

Compliance software like Simplifya, ProCanna and BuildMySOP let you quickly figure out what the regulations are in a given area, which can make it easier to find a good location, get set up and stay compliant. These applications, along with licensing trackers like Cannabiz Media, can also help you find where cannabis license opportunities are available and send you alerts whenever a state or city is accepting new applications.

Buy materials ahead

This is especially important now with the supply chain crisis still going on, but in general it’s a good idea to start gathering all the materials you need as soon as you’re certain about expanding. In IT in particular, pretty much everything including cash drawers, receipt printers, tablets, POS terminals, firewall appliances and laptops has been in pretty short supply. We’ve heard that it’s the same for just about all materials that go into setting up a new cannabis location whether it’s a dispensary, cultivation, distribution or manufacturing facility.

Lab technicians use the Hunter device during a test process. InstantLabs manufactures the Hunter system as well as test kits for food pathogens and species identification such as the catfish testing commercialization agreement outlined with the FDA.
In IT in particular, pretty much everything has been in short supply.

We’ve stayed on top of it and avoided delays by buying months ahead, purchasing a surplus of product and maintaining close communication with our vendors and distributors; we suggest you do the same for any products you’re purchasing internally.

If you’re buying online and the store says “in-stock,” you may want to contact the store/vendor to double-check that it’s accurate. Sometimes you buy it and you find out that “in-stock” means its parts are “in-stock” in a factory in Asia somewhere and your product is still months away from being manufactured, shipped and delivered to you.

Promote from within

When you’re growing is a good time to promote the all-stars already on your team, giving them a chance to expand their skills and take on greater responsibilities. We’ve seen this with some of our clients where they promote their star budtenders to shift leads or managers at their new stores, and store managers to district managers in new territories. It works out for everyone – the employee gets a raise and a step up the ladder, and you ensure you maintain your company’s culture and fill important positions with people you already know and trust (not to mention it’s often more cost-efficient to hire from within like this than to bring in someone new).

Hire from without when necessary

Sometimes promoting from within isn’t an option, like when you need someone with a particular skillset or level of experience.

Maybe your current COO has done a great job opening and operating 5 stores, but what about 50? If you want a sure thing, you’ll want to hire someone that’s already shown they can handle 50 or more stores, and most likely you’ll have to look outside the cannabis industry to find it.

You’re seeing this more and more in the cannabis industry – some are promoting from within, but many are also hiring experts from other companies and from outside the industry, including lots of people with strong retail, food manufacturing, merchandising, packaged goods and highly regulated goods (especially alcohol) backgrounds.

This can be more expensive than promoting from within and can potentially have a negative influence on company culture and morale, but on the other hand you’re getting valuable expertise that can help you take your cannabis business to the next level; and plus, you may even be able to hire these people at a relative bargain since there are many out there that are eager to work in such an exciting, new and high-growth industry.

Be ready for things to break down

Even if you’re fully prepared, you should still expect some kind of hiccup or hurdle with any new location rollout. It’s just the way it is on projects with an ambitious timeline and a lot of moving parts. The usual culprits are routine construction delays, cable companies and other utilities screwing up, storms, and having to adjust your schedule according to government inspectors on short notice. On some of our jobs in Canada, for example, we’ve run into a few blizzards and cameras and wires getting knocked out/frozen over; and on one occasion we were moderately inconvenienced setting up a store just up the street from the 2022 Ottawa trucker protests.

Don’t panic, don’t get frustrated. Your careful planning will at least ensure that most things go right, giving you the flexibility to react to the things that don’t.

Consider avoiding unlimited license markets

MedicineManTechGrow
Even if you’re fully prepared, you should still expect some kind of hiccup or hurdle with any new location rollout.

There’s a reason many MSOs avoid unlimited license markets like Oklahoma and Oregon. Limited license markets provide protection against competition. Unlimited license states are often free-for-alls and a race-to-the-bottom on pricing. They’re much tougher markets.

Have a vision

Rather than just wanting to grow and make a lot money, it can be helpful to have a unique, compelling and somewhat clear vision for your company, like Superette’s “making buying cannabis as fun as using it.” This helps you motivate your team, maintain your focus and cohesiveness as you add lots of new people, and differentiate yourself in a crowded market.

Consider franchising where it’s legal and makes sense

Our client Tokyo Smoke has opened over 80 locations in just over 3 years of operations. If that seems like too much growth for one company, you’re sort of right – some of Tokyo Smoke’s stores aren’t company-owned, they’re actually separately owned and managed franchises.

Now franchising a cannabis business isn’t legal everywhere at the moment, but where it is legal it’s a time-tested method of growing your brand and company footprint fast, and establishing dominant mindshare and market share that can’t easily be challenged or reversed.

Consider M&A

Sometimes M&A is the only option for breaking into a new market, like if the market is already oversaturated or not accepting new applications. Established cannabis businesses can start at $1-$10 million per location depending on the situation. Don’t quote us on it, but with some markets becoming saturated and sales declining in areas like Oregon and Canada, you may be able to get a good deal from someone that wants out of the business before things gets worse – assuming you’re bullish on a market rebound or think you can perform better in the market than the current owner.

bioMérieux, a leader in the in vitro diagnostics space and a supporter of the cannabis testing market, announced last month that they have achieved the first ever AOAC International approval for PCR Multiplex Detection of STEC and Salmonella in cannabis flower for their GENE-UP® PRO STEC/Salmonella Assay. The performance tested method approval for their new assay accomodates simultaneous enrichment and detection of STEC (Shiga Toxigenic Escherichia coli) and Salmonella spp. in cannabis samples.

The method is aimed at increasing efficiency in cannabis testing labs by reducing sample preparation time for microbiological testing. With the single enrichment and real-time multiplex PCR detection, bioMérieux says their new assay can provide reliable detection of STEC and Salmonella in 24 hours using just a single test.

PCR technology is one of the most widely utilized testing methods for detecting pathogens in a variety of matrices. bioMérieux claims it is easy to use, scientifically robust and reduces costs, time spent testing and errors.

Maria McIntyre, cannabis strategic operations business manager at bioMérieux, says that AOAC performance tested method approval is setting the bar for cannabis testing laboratories and furthering cannabis science. “AOAC International impacts cannabis science by setting analytical method standards that act as the benchmark for method validation,” says McIntyre. “This simplifies the validations needed by cannabis laboratories and assures the utmost confidence in product safety and human health.”

ISO/IEC 17025 Accreditation Falls Short for Cannabis Testing Laboratories

What is the role of the Quality Control (QC) Laboratory?

The Quality Control (QC) laboratory serves as one of the most critical functions in consumer product manufacturing. The QC laboratory has the final say on product release based on adherence to established product specifications. Specifications establish a set of criteria to which a product should conform to be considered acceptable for its intended use. Specifications are proposed, justified and approved as part of an overall strategy to ensure the quality, safety, and consistency of consumer products. Subsequently, the quality of consumer products is determined by design, development, Good Manufacturing Practice (GMP) controls, product and process validations, and the specifications applied throughout product development and manufacturing. These specifications are specifically the validated test methods and procedures and the established acceptance criteria for product release and throughout shelf life/stability studies.

The Code of Federal Regulations, 21 CFR Part 211, Good Manufacturing Practice for Finished Pharmaceuticals, provides the minimum requirements for the manufacture of safe products that are consumed by humans or animals. More specifically, 21 CFR Part 211: Subpart I-Laboratory Controls, outlines the requirements and expectations for the quality control laboratory and drug product testing. Additionally, 21 CFR Part 117, Current Good Manufacturing Practice, Hazard Analysis, and Risk-Based Preventative Controls for Human Food: Subpart B-Processes and Controls states that appropriate QC operations must be implemented to ensure food products are safe for consumption and food packing materials and components are safe and fit for purpose. Both food and drug products must be tested against established specifications to verify quality and safety, and laboratory operations must have the appropriate processes and procedures to support and defend testing results.

ISO/IEC 17025, General Requirements for the Competence of Testing and Calibration Laboratories is used to develop and implement laboratory management systems. Originally known as ISO/IEC Guide 25, first released in 1978, ISO/IEC 17025 was created with the belief that “third party certification systems [for laboratories] should, to the extent possible, be based on internationally agreed standards and procedures”7. National accreditation bodies are responsible for accrediting laboratories to ISO/IEC 17025. Accreditation bodies are responsible for assessing the quality system and technical aspects of a laboratory’s Quality Management System (QMS) to determine compliance to the requirements of ISO/IEC 17025. ISO/IEC 17025 accreditation is pursued by many laboratories as a way to set them apart from competitors. In some cannabis markets accreditation to the standard is mandatory.

The approach to ISO/IEC 17025 accreditation is typically summarizing the standard requirements through the use of a checklist. Documentation is requested and reviewed to determine if what is provided satisfies the item listed on the checklist, which correlate directly to the requirements of the standard. ISO/IEC 17025 covers the requirements for both testing and calibration laboratories. Due to the wide range of testing laboratories, the standard cannot and should not be overly specific on how a laboratory would meet defined requirements. The objective of any laboratory seeking accreditation is to demonstrate they have an established QMS. Equally as critical, for product testing laboratories in particular, is the objective to establish GxP, “good practices”, to ensure test methods and laboratory operations verify product safety and quality. ISO/IEC 17025 provides the baseline, but compliance to Good Laboratory Practice (GLP), Good Manufacturing Practice (GMP) and even Good Safety Practices (GSP) are essential for cannabis testing laboratories to be successful and demonstrate testing data is reliable and accurate.

Where ISO/IEC 17025 accreditation falls short

Adherence to ISO/IEC 17025, and subsequently receiving accreditation, is an excellent way to ensure laboratories have put forth the effort to establish a QMS. However, for product testing laboratories specifically there are a number of “gaps” within the standard and the accreditation process. Below are my “Top Five” that I believe have the greatest impact on a cannabis testing laboratory’s ability to maintain compliance and consistency, verify data integrity and robust testing methods, and ensure the safety of laboratory personnel.

Standard Operating Procedures (SOPs)

The understanding of what qualifies as a Standard Operating Procedure (SOP) is often misunderstood by cannabis operators. An SOP is a stand-alone set of step-by-step instructions which allow workers to consistently carry out routine operations, and documented training on SOPs confirms an employee’s comprehension of their job tasks. Although not required per the current version of the standard, many laboratories develop a Quality Manual (QM). A QM defines an organization’s Quality Policy, Quality Objectives, QMS, and the procedures which support the QMS. It is not an uncommon practice for cannabis laboratories to use the QM as the repository for their “procedures”. The intent of a QM is to be a high-level operations policy document. The QM is NOT a step-by-step procedure, or at least it shouldn’t be.

Test Method Transfer (TMT)

Some cannabis laboratories develop their own test methods, but a common practice in many cannabis laboratories is to purchase equipment from vendors that provide “validated” test methods. Laboratories purchase equipment, install equipment with pre-loaded methods and jump in to testing products. There is no formal verification (what is known as a Test Method Transfer (TMT)) by the laboratory to demonstrate the method validated by the vendor on the vendor’s equipment, with the vendor’s technicians, using the vendor’s standards and reagents, performs the same and generates “valid” results when the method is run on their own equipment, with their own technician(s), and using their own standards and reagents. When discrepancies or variances in results are identified (most likely the result of an inadequate TMT), changes to test methods may be made with no justification or data to support the change, and the subsequent method becomes the “validated” method used for final release testing. The standard requires the laboratory to utilize “validated” methods. Most laboratories can easily provide documentation to meet that requirement. However, there is no verification that the process of either validating in house methods or transferring methods from a vendor were developed using any standard guidance on test method validation to confirm the methods are accurate, precise, robust and repeatable. Subsequently, there is no requirement to define, document, and justify changes to test methods. These requirements are mentioned in ISO/IEC 17025, Step 7.2.2, Validation of Methods, but they are written as “Notes” and not as actual necessities for accreditation acceptance.

Change Control

The standard speaks to identifying “changes” in documents and authorizing changes made to software but the standard, and subsequently the accreditation criteria, is loose on the requirement of a Change Control process and procedure as part of the QMS. The laboratory is not offered any clear instruction of how to manage change control, including specific requirements for making changes to procedures and/or test methods, documented justification of those changes, and the identification of individuals authorized to approve those changes.

Out of Specification (OOS) results

The documentation and management of Out of Specification (OOS) testing results is perhaps one of the most critical liabilities witnessed for cannabis testing laboratories. The standard requires a procedure for “Nonconforming Work”. There is no mention of requiring a root cause investigation, no requirement to document actions, and most importantly there is no requirement to document a retesting plan, including justification for retesting. “Testing into compliance”, as this practice is commonly referred to, was ruled unacceptable by the FDA in the highly publicized 1993 court case United States vs. Barr Laboratories.

Laboratory Safety

FDAlogoSafe laboratory practices are not addressed at all in ISO/IEC 17025. A “Culture of Safety” (as defined by the Occupational Safety and Health Administration (OSHA)) is lacking in most cannabis laboratories. Policies and procedures should be established to define required Personal Protective Equipment (PPE), the safe handling of hazardous materials and spills, and a posted evacuation plan in the event of an emergency. Gas chromatography (GC) is a common test method utilized in an analytical testing laboratory. GC instrumentation requires the use of compressed gas which is commonly supplied in gas cylinders. Proper handling, operation and storage of gas cylinders must be defined. A Preventative Maintenance (PM) schedule should be established for eye wash stations, safety showers and fire extinguishers. Finally, Safety Data Sheets (SDSs) should be printed and maintained as reference for laboratory personnel.

ISO/IEC 17025 accreditation provides an added level of trust, respect and confidence in the eyes of regulators and consumers. However, the current process of accreditation misses the mark on the establishment of GxP, “good practices” into laboratory operations. Based on my experience, there has been some leniency given to cannabis testing laboratories seeking accreditation as they are “new” to standards implementation. In my opinion, this is doing cannabis testing laboratories a disservice and setting them up for failure on future accreditations and potential regulatory inspections. It is essential to provide cannabis testing laboratory owners and operators the proper guidance from the beginning and hold them up to the same rigor and scrutiny as other consumer product testing laboratories. Setting the precedence up front drives uniformity, compliance and standardization into an industry that desperately needs it.

Integrating a Culture of Quality Into the Cannabis Industry

By David Vaillencourt
1 Comment

The culture of the cannabis industry is filled with passion that many envy, and for valid reasons. The roots of the cannabis plant go back thousands of years. As of this writing, there are no documented human deaths that were caused by a phytocannabinoid overdose. However, it is not all rainbows and unicorns.

Before breaking ground, fundraising, proper facility design, competitive application and permitting requirements are just the start. Once operating, businesses struggle to stay current with regulations that continue to evolve. Cannabis cultivators struggle to scale while mitigating pest infestations, which is a part of life in the conventional agricultural industry. A lack of consistent products frustrates consumers, while regulators and policy makers continue to struggle on the best way to regulate a commodity that has seemingly endless demand. The reality is dizzying!

However, amidst all of the challenges and opportunities, a continually overlooked tool stands out: a Quality Management System (QMS). Merriam-Webster defines a system as “an organized set of doctrines, ideas, or principles usually intended to explain the arrangement or working of a systematic whole.”

A QMS documents processes, procedures and responsibilities that ultimately direct an organization’s activities to meet customer and regulatory requirements as well as continually improve its effectiveness and efficiency. In other words – it steers innovation through the collection of data while ensuring products are safe for the consumer. For further reading, the American Society for Quality (ASQ), now over 70 years old, is an excellent resource and provider of resources and formal training programs that are recognized and revered around the world.

Step 1: Define your stakeholder requirements

This all starts with knowing your stakeholder (e.g., customer, regulatory body) requirements. For simplicity’s sake, let’s start with your customer; at a fundamental level, they expect safe, consistent and reliable products that impart a certain experience.

How does that translate into specifications? Let’s look at them one at a time.

What does “safe” mean? For an edible, safe means the product is free of physical, chemical and microbial hazards. Knowing what potential impurities could be in your product requires understanding your raw materials (inputs) and the manufacturing process. To take a deeper dive, some of the aspects of safety and quality, product specifications and testing considerations are discussed in this recent Cannabis Industry Journal article by Dr. Roggen and Mr. Skrinskas here.

An example of a compliant label in Oregon

What does “consistent” mean? This builds off and complements the safety profile. It could mean a consistent fill level, an acceptable range of cannabinoid concentration, and so on. For example, in the US Pharmacopeia’s peer-reviewed article about quality attributes of cannabis inflorescence (commonly known as flower or bud), they recommend 20% as the acceptable variance in cannabinoid content. For a product labeled as having 25% THC, the product will actually test to between 20% and 30%. This may be surprising, and discomforting for some, but the reality is that products on the market consistently fail to meet label claims.

What does “reliable” mean? That could mean that you always have inventory of certain products on the shelves at your dispensary. Defining “always” as a SMART goal – perhaps it means that you will have your top 3 products in stock at least 90% of the time. Customers need to feel like they can rely on your business to provide them with the products they want. Take the time to capture the data on what your customers want and work to satisfy their needs and you’ll watch your business really accelerate.

Step 2: Build your processes to meet these expectations

This is where your written standard operating procedures (SOPs), forms and records come into play. Your SOPs serve to memorialize your operations for consistency. Most SOPs in the cannabis industry are not written by the actual operators of a process. Rather, they are written by the legal and compliance team without review by the operators to confirm that what they are stating reflects operational reality. The audience needs to be the operators. Without effective SOPs that are utilized by your employees, your business will struggle to meet the established specifications. Cannabis businesses in Colorado, the oldest regulated adult-use cannabis market in the United States, continue to see 1 in 8 of their products fail final product testing! Cannabis businesses that understand their processes, document them in SOPs and have records to prove they follow their SOPs (see Step 3) are able to reduce errors that ultimately lead to costly rework and product failures.

Consistency in quality standards requires meticulous SOPs

Step 3: Monitor and improve

You have your requirements, you have your process, but how do you know that they are being adhered to? By the time you have results from a third-party lab, it’s too late. Look internally. Records and logs that show preventive maintenance was performed, room and canopy temperature and humidity checks, inventory reports, production records, extraction equipment report and employee training records shouldn’t be filled out only to be filed away. These records are data, which is your most valuable tool. Unfortunately, records are one of the most overlooked assets in today’s cannabis business. A team independent from operations (typically a Quality Unit) should be regularly reviewing these for inconsistencies and trends that can alert you to catastrophic failures before they occur.

Initially, the additional expenditure and learning curve may make this seem like an added burden, but keep in mind that succeeding in today’s cannabis industry requires long-term customer retention. By biting off one piece at a time, you can slowly implement a QMS that will improve your business, increase customer satisfaction, and ensure your brand is a staple for years to come. Remember, quality and compliance is a journey, not a “set it and forget it” situation.

The definition of a Quality Management System includes ‘continuous improvement’. Look forward to a future article which will discuss the importance of tools like a CAPA Program – Corrective Action Preventive Action (which all cannabis license holders in Colorado are required to have in place as of January 1, 2021) and how they complete your QMS, keeping you compliant and mitigating your business risks!

Quality Plans for Lab Services: Managing Risks as a Grower, Processor or Dispensary, Part 4

By Dr. Edward F. Askew

Dr. Ed Askew

In the last three articles, I discussed the laboratory’s responses or defenses used to reply to your questions about laboratory results that place stress on the success of your business. The Quality Control (QC) results can cause this stress if they are not run correctly to answer the following questions:

  1. Are the laboratory results really true?
  2. Can the laboratory accurately analyze sample products like my sample?
  3. Can the laboratory reproduce the sample results for my type of sample?

Now let’s discuss the most important QC test that will protect your crop and business. That QC sample is the Matrix Sample. In the last article in this series, you were introduced to many QC samples. The Matrix Sample and Duplicate were some of them. Take a look back at Part 3 to familiarize yourself with the definitions.

The key factors of these QC sample types are:

  1. Your sample is used to determine if the analysis used by the laboratory can extract the analyte that is being reported back to you. This is performed by the following steps:
    1. Your sample is analyzed by the laboratory as received.
    2. Then a sub-sample of your sample is spiked with a known concentration of the analyte you are looking for (e.g. pesticides, bacteria, organic chemicals, etc.).
    3. The difference between the sample with and without a spike indicates whether the laboratory can even find the analyte of concern and whether the percent recovery is acceptable.
    4. Examples of failures are from my experiences:
      1. Laboratory 1 spiked a known amount of a pesticide into a wastewater matrix. (e.g. Silver into final treatment process water). The laboratory failed to recover any of the spiked silver. Therefore the laboratory results for these types of sample were not reporting any silver, but silver may be present. This is where laboratory results would be false negatives and the laboratory method may not work on the matrix (your sample) correctly. .
      2. Laboratory 2 ran an analysis for a toxic compound (e.g. Cyanide in final waste treatment discharge). A known amount of cyanide was spiked into a matrix sample and 4 times the actual concentration of that cyanide spike was recovered. This is where laboratory results would be called false positives and the laboratory method may not work on the matrix (your sample) correctly.
  2. Can the laboratory reproduce the results they reported to you?
    1. The laboratory needs to repeat the matrix spike analysis to provide duplicate results. Then a comparison of the results from the first matrix spike with its duplicate results will show if the laboratory can duplicate their test on your sample.
      1. If the original matrix spike result and the duplicate show good agreement (e.g. 20% relative percent difference or lower). Then you can be relatively sure that the result you obtained from the laboratory is true.
      2. But, if the original matrix spike result and the duplicate do not show good agreement (e.g. greater than 20% relative percent difference). Then you can be sure that the result you obtained from the laboratory is not true and you should question the laboratory’s competence.

Now, the question is why a laboratory would not perform these matrix spike and duplicate QC samples? Well, the following may apply:

  1. These matrix samples take too much time.
  2. These matrix samples add a cost that the laboratory cannot recover.
  3. These matrix samples are too difficult for the laboratory staff to perform.
  4. Most importantly: Matrix samples show the laboratory cannot perform the analyses correctly on the matrix.

So, what types of cannabis matrices are out there? Some examples include bud, leaf, oils, extracts and edibles. Those are some of the matrices and each one has their own testing requirements. So, what should you require from your laboratory?

  1. The laboratory must use your sample for both a matrix spike and a duplicate QC sample.
  2. The percent recovery of both the matrix spike and the duplicate will be between 80% and 120%. If either of the QC samples fail, then you should be notified immediately and the samples reanalyzed.
  3. If the relative percent difference between the matrix spike and the duplicate will be 20% or less. If the QC samples fail, then you should be notified immediately and the samples should be reanalyzed.

The impact of questionable laboratory results on your business with failing or absent matrix spike and the duplicate QC samples can be prevented. It is paramount that you hold the laboratory responsible to produce results that are representative of your sample matrix and that are true.

The next article will focus on how your business will develop a quality plan for your laboratory service provider with a specific focus on the California Code Of Regulations, Title 16, Division 42. Bureau Of Cannabis Control requirements.
