As mentioned in Part 1, the physiological effects of cannabis are mediated by a group of structurally related organic compounds known as cannabinoids. The cannabinoids are biosynthetically produced by a growing cannabis plant and Figure 1 details the biosynthetic pathways leading to some of the most important cannabinoids in plant material.
Figure 1: The biosynthetic pathway of phytocannabinoid production in cannabis has been deeply studied through isotopic labeling experiments
The analytical measurement of cannabinoids is important to ensure the safety and quality of cannabis as well as its extracts and edible formulations. Total cannabinoid levels can vary significantly between different cultivars and batches, from about 5% up to 20% or more by dry weight. Information on cannabinoid profiles can be used to tailor cultivars for specific effects and allows end users to select an appropriate dose.
Routine Analysisvs. Cannabinomics
Several structurally analogous groups of cannabinoids exist. In total, structures have been assigned for more than 70 unique phytocannabinoids as of 2005 and the burgeoning field of cannabinomics seeks to comprehensively measure these compounds.¹
Considering practical potency analysis, the vast majority of cannabinoid content is accounted for by 10-12 compounds. These include Δ9-tetrahydrocannabinol (THC), cannabidiol (CBD), cannabigerol (CBG), Δ9-tetrahydrocannabivarian (THCV), cannabidivarin (CBDV) and their respective carboxylic acid forms. The cannabinoids occur primarily as carboxylic acids in plant material. Decarboxylation occurs when heat is applied through smoking, vaporization or cooking thereby producing neutral cannabinoids which are more physiologically active.
Potency Analysis by HPLC and GC
Currently, HPLC and GC are the two most commonly used techniques for potency analysis. In the case of GC, the heat used to vaporize the injected sample causes decarboxylation of the native cannabinoid acids. Derivatization of the acids may help reduce decarboxylation but overall this adds another layer of complexity to the analysis² ³. HPLC is the method of choice for direct analysis of cannabinoid profiles and this technique will be discussed further.
A sample preparation method consisting of grinding/homogenization and alcohol extraction is commonly used for cannabis flower and extracts. It has been shown to provide good recovery and precision² ³. An aliquot of the resulting extract can then be diluted with an HPLC compatible solvent such as 25% water / 75% acetonitrile with 0.1% formic acid. The cannabinoids are not particularly water soluble and can precipitate if the aqueous percentage is too high.
To avoid peak distortion and shifting retention times the diluent and initial mobile phase composition should be reasonably well matched. Another approach is to make a smaller injection (1-2 µL) of a more dissimilar solvent. The addition of formic acid or ammonium formate buffer acidifies the mobile phase and keeps the cannabinoid acids protonated.
The protonated acids are neutral and thus well retained on a C18 type column, even at higher (~50% or greater) concentrations of organic solvent² ³.
Detection is most often done using UV absorbance. Two main types of UV detectors are available for HPLC, single wavelength and diode array. A diode array detector (DAD) measures absorbance across a range of wavelengths producing a spectrum at each point in a chromatogram while single wavelength detectors only monitor absorbance at a single user selected wavelength. The DAD is more expensive, but very useful for detecting coelutions and interferences.

Almost as soon as cannabis became recreationally legal, the public started to ask questions about the safety of products being offered by dispensaries – especially in terms of pesticide contamination. As we can see from the multiple recalls of product there is a big problem with pesticides in cannabis that could pose a danger to consumers. While The Nerd Perspective is grounded firmly in science and fact, the purpose of this column is to share my insights into the cannabis industry based on my years of experience with multiple regulated industries with the goal of helping the cannabis industry mature using lessons learned from other established markets. In this article, we’ll take a look at some unique challenges facing cannabis testing labs, what they’re doing to respond to the challenges, and how that can affect the cannabis industry as a whole.

The Big Challenge
Over the past several years, laboratories have quickly ‘grown up’ in terms of technology and expertise, improving their methods for pesticide detection to improve data quality and lower detection limits, which ultimately ensures a safer product by improving identification of contaminated product. But even though cannabis laboratories are maturing, they’re maturing in an environment far different than labs from regulated industry, like food laboratories. Food safety testing laboratories have been governmentally regulated and funded from almost the very beginning, allowing them some financial breathing room to set up their operation, and ensuring they won’t be penalized for failing samples. In contrast, testing fees for cannabis labs are paid for by growers and producers – many of whom are just starting their own business and short of cash. This creates fierce competition between cannabis laboratories in terms of testing cost and turnaround time. One similarity that the cannabis industry shares with the food industry is consumer and regulatory demand for safe product. This demand requires laboratories to invest in instrumentation and personnel to ensure generation of quality data. In short, the two major demands placed on cannabis laboratories are low cost and scientific excellence. As a chemist with years of experience, scientific excellence isn’t cheap, thus cannabis laboratories are stuck between a rock and a hard place and are feeling the squeeze.
Responding to the Challenge
One way for high-quality laboratories to win business is to tout their investment in technology and the sophistication of their methods; they’re selling their science, a practice I stand behind completely. However, due to the fierce competition between labs, some laboratories have oversold their science by using terms like ‘lethal’ or ‘toxic’ juxtaposed with vague statements regarding the discovery of pesticides in cannabis using the highly technical methods that they offer. This juxtaposition can then be reinforced by overstating the importance of ultra-low detection levels outside of any regulatory context. For example, a claim stating that detecting pesticides at the parts per trillion level (ppt) will better ensure consumer safety than methods run by other labs that only detect pesticides at concentrations at parts per billion (ppb) concentrations is a potentially dangerous claim in that it could cause future problems for the cannabis industry as a whole. In short, while accurately identifying contaminated samples versus clean samples is indeed a good thing, sometimes less isn’t more, bringing us to the second half of the title of this article.
Less isn’t always more…
The Milky Way
In my last article, I illustrated the concept of the trace concentrations laboratories detect, finishing up with putting the concept of ppb into perspective. I wasn’t even going to try to illustrate parts per trillion. Parts per trillion is one thousand times less concentrated than parts per billion. To put ppt into perspective, we can’t work with water like I did in my previous article; we have to channel Neil deGrasse Tyson.
The Milky Way galaxy contains about 100 billion stars, and our sun is one of them. Our lonely sun, in the vastness of our galaxy, where light itself takes 100,000 years to traverse, represents a concentration of 10 ppt. On the surface, detecting galactically-low levels of contaminants sounds wonderful. Pesticides are indeed lethal chemicals, and their byproducts are often lethal or carcinogenic as well. From the consumer perspective, we want everything we put in our bodies free of harmful chemicals. Looking at consumer products from The Nerd Perspective, however, the previous sentence changes quite a bit. To be clear, nobody – nerds included – wants food or medicine that will poison them. But let’s explore the gap between ‘poison’ and ‘reality’, and why that gap matters.
In reality, according to a study conducted by the FDA in 2011, roughly 37.5% of the food we consume every day – including meat, fish, and grains – is contaminated with pesticides. Is that a good thing? No, of course it isn’t. It’s not ideal to put anything into our bodies that has been contaminated with the byproducts of human habitation. However, the FDA, EPA, and other governmental agencies have worked for decades on toxicological, ecological, and environmental studies devoted to determining what levels of these toxic chemicals actually have the potential to cause harm to humans. Rather than discuss whether or not any level is acceptable, let’s take it on principle that we won’t drop over dead from a lethal dose of pesticides after eating a salad and instead take a look at the levels the FDA deem ‘acceptable’ for food products. In their 2011 study, the FDA states that “Tolerance levels generally range from 0.1 to 50 parts per million (ppm). Residues present at 0.01 ppm and above are usually measurable; however, for individual pesticides, this limit may range from 0.005 to 1 ppm.” Putting those terms into parts per trillion means that most tolerable levels range from 100,000 to 50,000,000 ppt and the lower limit of ‘usually measurable’ is 10,000 ppt. For the food we eat and feed to our children, levels in parts per trillion are not even discussed because they’re not relevant.
A specific example of this is arsenic. Everyone knows arsenic is very toxic. However, trace levels of arsenic naturally occur in the environment, and until 2004, arsenic was widely used to protect pressure-treated wood from termite damage. Because of the use of arsenic on wood and other arsenic containing pesticides, much of our soil and water now contains some arsenic, which ends up in apples and other produce. These apples get turned into juice, which is freely given to toddlers everywhere. Why, then, has there not an infant mortality catastrophe? Because even though the arsenic was there (and still is), it wasn’t present at levels that were harmful. In 2013, the FDA published draft guidance stating that the permissible level of arsenic in apple juice was 10 parts per billion (ppb) – 10,000 parts per trillion. None of us would think twice about offering apple juice to our child, and we don’t have to…because the dose makes the poison.
How Does This Relate to the Cannabis Industry?
The concept of permissible exposure levels (a.k.a. maximum residue limits) is an important concept that’s understood by laboratories, but is not always considered by the public and the regulators tasked with ensuring cannabis consumer safety. As scientists, it is our job not to misrepresent the impact of our methods or the danger of cannabis contaminants. We cannot understate the danger of these toxins, nor should we overstate their danger. In overstating the danger of these toxins, we indirectly pressure regulators to establish ridiculously low limits for contaminants. Lower limits always require the use of newer testing technologies, higher levels of technical expertise, and more complicated methods. All of this translates to increased testing costs – costs that are then passed on to growers, producers, and consumers. I don’t envy the regulators in the cannabis industry. Like the labs in the cannabis industry, they’re also stuck between a rock and a hard place: stuck between consumers demanding a safe product and producers demanding low-cost testing. As scientists, let’s help them out by focusing our discussion on the real consumer safety issues that are present in this market.

In the last article I referred to the analogy of the analytical reference material being a keystone of the laboratory foundation, the stone upon which all data relies. I then described the types of reference materials and their use in analytical testing in general terms. This article will describe the steps required to properly manufacture and deliver a certified reference material (CRM) along with the necessary documentation.
A CRM is an exclusive reference material that meets strict criteria defined by ISO Guide 34 and ISO/IEC 17025. ISO is the International Organization for Standardization and IEC is the International Electrotechnical Commission. These organizations work together to set globally recognized standards. In order for a reference material to be labeled as a CRM it must 1) be made with raw or starting materials which are characterized using qualified methods and instruments, 2) be produced in an ISO-accredited lab under documented procedures, and 3) fall under the manufacturer’s scopes of accreditation. Verifying a CRM supplier has these credentials is easily done by viewing their certificates which should include their scopes of accreditation.
There are many steps required to produce a CRM that meets the above three criteria. The first step requires a review of the customer’s, or end-user’s requirements to carefully define what is to be tested, at what levels and which analytical workflow will be used. Such information enables the producer to identify the proper compounds and solvents required to properly formulate the requested CRM.
The next step requires sourcing and acquiring the raw, or starting materials, then verifying their compatibility and stability using stability and shipping studies in accordance with ISO requirements. Next the chemical identify and purity of the raw materials must be characterized using one or more analytical techniques such as: GC-FID, HPLC, GC-ECD, GC-MS, LC-MS, refractive index and melting point. In some cases, the percent purity is changed by the producer when their testing verifies it’s different from the supplier label. All steps are of course documented.
The producer’s analytical balances must be verified using NIST traceable weights and calibrated annually by an accredited third party provider to guarantee accurate measurement. CRMs must be prepared using Class A volumetric glassware, and all ampules and vials used in preparation and final packaging must be chemically treated to prevent compound degradation during storage. Next, CRMs are packaged in an appropriate container, labeled then properly stored to maintain the quality and stability until it’s ready to be shipped. All labels must include critical storage, safety and shelf life information to meet federal requirements. The label information must be properly linked to documentation commonly referred to as a certificate of analysis (COA) which describes all of the above steps and verifies the traceability and uncertainty of all measurements for each compound contained in the CRM.
My company, RESTEK, offers a variety of documentation choices to accompany each CRM. Depending on the intended use and data quality objectives specified by the end-user, which were defined way back at the first step, three options are typically offered: They include gravimetric only, qualitative which includes gravimetric, and fully quantitative which includes all three levels of documentation. The graphic to the right summarizes the three options and what they include.
It’s important to understand which level you’re purchasing especially when ordering a custom CRM from a supplier. Most stock CRMs include all three levels of documentation, but it’s important to be sure.
Understanding what must be done to produce and deliver a CRM sets it apart from other reference material types, however it’s important to understand there are some instances where CRMs are either not available, nor required and in those situations other types of reference materials are perfectly acceptable.

Last week, Pennsylvania Department of Health Secretary Dr. Karen Murphy announced the formation of temporary regulations for cannabis growers and processors in the state, according to a press release. Those temporary rules were published on Saturday, October 29. Secretary Murphy asked for public comment on developing regulations for dispensaries as well.
The PA Department of Health published the new set of temporary regulations this past Saturday, outlining “the financial, legal and operational requirements needed by an individual to be considered for a grower/processor permit, as well as where the facilities can be located.” The regulations also discuss tracking systems, equipment maintenance, safety issues, disposal of cannabis, tax reporting, pesticides, recalls and insurance requirements. “One of our biggest accomplishments to date is the development of temporary regulations for marijuana growers and processors,” says Secretary Murphy. “We received nearly 1,000 comments from members of the community, the industry and our legislative partners.”
The general provisions published on Saturday outline the details of the application process, fees, inspections, reporting, advertising and issues surrounding locations and zoning. The temporary regulations for growers and processors delve into the minutia of regulatory compliance for a variety of issues: including security, storage, maintenance, transportation, tracking, disposal, recall, pesticides and packaging and safety requirements. A list of pesticides permitted for use can also be found at the bottom of the rules.
PA Department of Health Secretary Dr. Karen Murphy
The document discusses the regulations for performing voluntary and mandatory recalls in great detail. It requires thorough documentation and standard operating procedures for the disposal of contaminated products, cooperation with the Department of Health and appropriate communications with those affected by the recall.
The department has yet to release temporary regulations for laboratories and dispensaries, but hopes to do so before the end of the year. “I am encouraging the public – and specifically the dispensary community – to review the temporary regulations and provide us with their feedback,” says Secretary Murphy. “The final temporary regulations for dispensaries will be published in the Pennsylvania Bulletin by the end of the year.”
Since Governor Tom Wolf signed the medical cannabis program bill into law in April 2016, the state has made considerable progress to develop the program, including setting up a physician workgroup, public surveys for developing temporary rules and a request for information for electronic tracking IT solutions. The PA Department of Health expects to implement the program fully in the next 18 to 24 months.
Even though half of U.S. states and the District of Colombia now permit the possession of medical or recreational cannabis, state regulatory bodies differ greatly in their approaches to managing our industry. In Washington, anyone over the age of 21 can legally possess one ounce of usable cannabis and/or seven grams of concentrate. In Minnesota, patients are only allowed to purchase non-smokable cannabis in pill, liquid or oil form.
Given these substantial differences, it is no surprise that the application process to open a dispensary or cultivation facility also varies from state to state. The question I am most often asked (and catch myself mulling over late at night) is what can applicants do to ensure their success, regardless of where they are applying?
Recently we helped a client secure one of the first 15 licenses issued to grow medical cannabis in Maryland. The Maryland application process was particularly unique because most of the applicants had political or law-enforcement ties, or were connected to successful out-of-state growers. That experience, along with our work in places like Arizona, Colorado and Florida, has shown me the importance of teamwork, diversity and security in developing a winning application.
So here are my suggestions for ensuring a successful submission, regardless of which state you are operating in:
Build the Right Team. My dad likes to say, “Use the right tool for the right job.” I think the same is true about creating the team for your application. Do not assume one or two people will be able to fill all of the required roles. You will need experts in a range of different areas including medicine, pharmacology, capital investment, cultivation, real estate, security and law.
Focus on Diversity. I think one of the reasons we have been successful in helping clients secure applications (we are six for six, in six different states) is our commitment to gender, racial and even geographic diversity. For example, we recently helped a client secure a license in an economically underdeveloped area. I think our choice to headquarter the new business outside of the metropolitan corridor was at least partially responsible for our success.
The Devil is in the Details. According to ArcView Market Research, the cannabis industry is expected to be worth $23 billion by 2020. If you want to be one of the organizations selected by your state to sell cannabis, you need to have your act together. Most applications ask incredibly detailed questions. Therefore it is essential that you answer them thoroughly and accurately. All answers should be in compliance with your state’s regulations.
Put Safety First. You will need a comprehensive plan that takes all aspects of security into account. This includes everything from hiring security guards to purchasing cameras, and implementing internal anti-theft procedures. Regardless of the size of your operation, safety should be a primary consideration.
Secure Funding. Successful cannabis businesses require capital. It’s important to be realistic about the amount of money you will need to have on hand. Application costs typically range from $500,000 to $1 million. This will cover things like hiring an architect or leasing land. Ideally, your organization will have another $5 to $10 million or more available to start your project once you’ve been approved so that you can quickly become operational.
Connect With Your Community. It is essential to consider the impact of your business on the community. Being a good corporate citizen means being transparent and engaging in a two-way dialogue with neighbors, government officials and patients. I strongly recommend that my clients develop a comprehensive community outreach plan that designates which organizations they plan to work with, (hospitals or universities, for example) and what the nature of those partnerships will be.
Lezli Engelking founded the Foundation of Cannabis Unified Standards (FOCUS) in 2014 to protect public health, consumer safety, and safeguard the environment by promoting integrity in the cannabis industry through the use of standards. Standards are an agreed upon way of doing things and specify guidelines or requirements for producing goods or providing services, according to FOCUS.
Peter Maguire, committee chair of the FOCUS Cultivation Standard
Standards can take the form of a “reference document, which may include specifications, guidelines, conditions or requirements for products, operations, services, methods, personnel and systems on how to design, operate, manufacture or manage something.” Peter Maguire, VP of System Applications for Lighthouse Worldwide Solutions and committee chair of the FOCUS Cultivation standard, joined the organization wanting to make a positive impact on the industry that is in line with protecting people and medical patients. He sees so much variability in the industry and the need to homogenize standard operating procedures (SOPs). “I have worked with multiple cultivation facilities and a few of them have operating procedures in place but having them in place is only half the solution- it’s critical to have the right ones in place,” says Maguire. He has twenty years of experience in contamination control in manufacturing, before entering the cannabis industry.
The FOCUS cultivation standard was created by experts who have years of experience in both cannabis cultivation, good agricultural practices and in the tightly regulated pharmaceutical industry. “FOCUS created these guidelines as a sort of roadmap for success in business; You need to keep your employees healthy and your products safe to survive in the long term,” says Maguire. We sit down with Lezli Engelking to find out how the standards are created, what makes them significant and what businesses can gain by working with them.
CannabisIndustryJournal: Why are standards important?
Lezli: Standards are the international language for trade – they exist in every industry. “The U.S. Department of Commerce estimates that standards and conformity assessment impact more than 80% of global commodity trade.” FOCUS is not reinventing the wheel with what we are doing. We are simply adapting a business model the federal government already uses. In the 80s, when the heroin epidemic swept across the US, methadone clinics popped up in every state in the country within two years. The clinics were all operating under different state, city and county regulations – much like the cannabis industry is today. The federal government took a look at the situation and decided they needed a way to regulate these clinics in order to protect public health and safety. They released a Request For Proposal (RFP) looking for an organization to create voluntary-consensus standards and a third-party certification system for the methadone clinics. Commission on Accreditation of Rehabilitation Facilities (CARF) is the organization that answered and won that RFP. CARF continues to work with Health and Human Services to maintain the standards and provide third-party certification to the clinics today. FOCUS develops international, voluntary consensus standards and a third party certification program for the global cannabis industry based on the CARF model. This is extremely important, because of the National Technology Transfer and Advancement Act, (Public Law 104-115), signed into law March 7, 1996 by President Clinton. The act requires that all federal agencies use standards developed by voluntary-consensus standards bodies, instead of government-unique standards wherever possible. Perhaps even more importantly, the Act includes provisions that encourage federal agencies to partner with the private sector in the development of standards that not only help improve the efficiency and effectiveness of government, but also strengthen the U.S. position in the global marketplace.
CIJ: What exactly goes into developing a voluntary-consensus standard?
Lezli: Voluntary-Consensus refers to the type of standard and how it is developed. Everyone who participates in the development of voluntary-consensus standards does so on a voluntary basis. Committee members must come to a consensus on every point within the standard- down to every comma or semicolon. Once the development process is complete, the standards must undergo a 30-day public review period. The process for developing voluntary-consensus standards is designated by International Organization for Standardization (ISO). ISO has member agencies in 163 countries that participate in the development of standards. The American National Standards Institute (ANSI) is the American body for ISO. FOCUS follows all ISO/ANSI guidelines in the standards development process. This is extremely important because it means FOCUS standards are suitable for accreditation and adoption into regulations according to the National Technology Transfer and Advancement Act. All voluntary-consensus standards are developed under the principles of:
Openness| Participation in the standard development process is open to individuals with a stake in the standard who bring useful expertise along with the spirit and willingness to participate.
Balance| Focus stakeholder groups involve all stakeholder groups: industry, regulatory, quality assurance, medical, law enforcement, business, research, consumers, patients and the general public.
Voluntary-Consensus| Individual subcommittees of volunteers develop each area of the standard, offering their unique expertise to form a consensus. They are not paid for their participation.
Lack of Dominance| No party has dominant representation, or influence to the exclusion of fair and equitable consideration of other viewpoints.
CIJ: More specifically, how are the FOCUS standards developed?
Lezli: To create a baseline standard, FOCUS utilized World Health Organization (WHO) guidelines for Good Manufacturing Practices (GMP), Good Agricultural Practices (GAP), Good Laboratory Practices (GLP), Code of Federal Regulations (CFR) for pharmaceutical GMPs, nutraceutical GMPs, food safety standards, OSHA and HACCP. From there, applicable cannabis regulations from around the world were added. All of this information was compiled into auditor-style checklists. Each committee member was provided time to go edit, remove or add to items in the checklist on their own. Over the next two years, each of the eight committees had monthly meetings, going through and coming to a consensus on each line item of the standard. Once the committees completed development, the standards were open for a 30-day Public Review to collect comments and feedback. The first eight FOCUS standards, completed and ready for use, cover Cultivation, Retail, Extraction, Infused Products, Laboratory, Security, Sustainability and Packaging & Labeling.
FOCUS is currently recruiting committee members to begin development of five new cannabis standards later this year: Advertising/Marketing, Insurance, Banking/Finance, Patient Care and Research. Committees will receive a list of proposed suggestions for what should be considered in developing the standards. Each committee member will develop a list to select criteria they think should be included into the standard. FOCUS will compile the lists, then committees will go through the monthly standards development/vetting process for each line item in the standard.
CIJ: So what does a business have to gain by adopting a FOCUS standard?
Lezli: Compliance becomes easily manageable with the FOCUS software platform, integrating standards, training and SOPs into the everyday operations of the business. FOCUS certified clients could expect to reduce costs, reduce risk and reduce liability by assuring they are producing safe, quality and consistent products. FOCUS certification allows a business to differentiate themselves from their competitors, and prove to their patients and customers they can trust their products. Certification also allows businesses to access reasonable insurance rates and drives interest from investors.
FOCUS is here to partner with cannabis businesses. We are there to hold their hand, by providing guidance and assistance along every step of the way. Unlike state mandated audits that delineate what a business is doing right or wrong, FOCUS is an on-going compliance management system. We are here to make sure a business runs as efficiently as possible and take the guesswork out of compliance. Under FOCUS certification, a business receives ongoing consulting, customized SOPs, employee training and a documentation management software system to track and prove compliance.
CIJ: Can you give us an update on FOCUS’ progress in 2016?
Lezli: A large milestone for FOCUS this year, aside from completing version one of the standards, is choosing an appropriate software platform, (Power DMS) to house the standards and provide an ongoing compliance management system for our clients. Power DMS also houses regulatory standards for law enforcement; health care, federal aviation and fire departments, so most agencies in public health are already familiar with it. The familiarity and access to this platform is a huge benefit on the regulatory side. It allows first responders to access the schematics of a FOCUS certified client in the event of an emergency. This is crucial in the event of an explosion from extraction equipment, or a fire in a cultivation facility, as without first identifying where the hazards are, they will not access the facility. The FOCUS software platform allows first responders access to all pertinent information through computers in police cars, ambulances, or fire trucks.
For the industry, the FOCUS software platform is equally as impressive. Not only does the platform house the standards and all SOPs, it is also complete compliance management system. FOCUS certified clients have a simple management tool that houses all training and documentation, assuring all required compliance documentation can be easily accessed at any time. The platform also allows FOCUS certified clients to provide access to governing bodies in advance of state audits –streamlining the process and minimizing time and interruption caused by state audits. The FOCUS platform tracks all changes to required documents, provides real time updates on employee training, creates appropriate traceability logs, and provides updates on regulatory changes, including which SOPs need to be changed to maintain compliance. The platform allows FOCUS to be way more than an auditing company. FOCUS is a partnership in compliance for cannabis companies wanting to maintain good business practices and stay compliant with regulations.
We have about 140 new committee members that will assist existing committees with standards updates and participate in the development of the next set of FOCUS standards for advertising/marketing, banking/finance, research, patient care and insurance. All committees will convene before 2017.
Last week, Steep Hill Labs, Inc. announced plans to expand on the East Coast, including licensing for laboratories in Washington, D.C. and Pennsylvania. The cannabis testing company now is operating or developing in seven states, the District of Columbia along with an official arrangement with a research university in Jamaica, according to Cathie Bennett Warner, director of public relations at Steep Hill.
The same team of physicians that oversees the Steep Hill laboratory in Maryland will operate the Pennsylvania and D.C. labs. Heading that team is chief executive officer Dr. Andrew Rosenstein, chief of the division of Gastroenterology at University of Maryland Saint Joseph Medical Center and assistant clinical professor of Gastroenterology and Hepatology at the University of Maryland Medical Center. Dr. Rosenstein has been recognized by Baltimore Magazine as a top doctor in the Baltimore area, according to a press release.
Dr. Andrew Rosenstein, CEO of Steep Hill Maryland, PA and D.C.
According to Dr. Rosenstein, they want to provide accurate clinical results for trials with patients using cannabis. “All clinical trials will require a competent, credible and reliable lab partner and that is what we are bringing to the field- and that is why we are working with Steep Hill,” says Dr. Rosenstein. With team members having backgrounds in pathology, molecular diagnostics, clinical chemistry, microbiology and genetics, it should come as no surprise that they plan to participate in clinical research.
Dr. Rosenstein’s vested interest in cannabis safety stems from prior experience with his patients using cannabis. “Over the past five years, we have seen an increased number of patients using cannabis, particularly for managing the side effects of Crohn’s disease and cancer treatment,” says Dr. Rosenstein. “They would bring it up to us and at the time I didn’t know much about it, but anecdotally it’s really clear that a lot of patients have great responses to it.” Not knowing much about the preparation or safety of cannabis at the time led Dr. Rosenstein to advise patients to be very careful if they are immunocompromised.

“When a patient is immunocompromised, a bacterial or fungal infection can be lethal, so because we had patients using cannabis, we wanted to make sure it was safe,” says Dr. Rosenstein. So when Maryland legalized medical cannabis, Dr. Rosenstein and his team saw the need to protect patient safety and Steep Hill was a perfect fit. “We really didn’t want to reinvent the wheel so we looked for someone to partner with,” says Dr. Rosenstein. “Steep Hill has the best technology and the best credibility and we didn’t want to compromise on quality and safety issues. They felt the same way so we partnered with them and culturally it has been a great fit.”
Steep Hill Express in Berkeley, CA- MD,PA and D.C. will have a similar offering of instant potency analysis
The new laboratories plan to offer a similar range of services that are offered at other Steep Hill labs, such as rapid potency testing for THC-A, ∆-9-THC, CBD, CBD-A and moisture. But Dr. Rosenstein sees clinical opportunities in the East Coast medical hubs. “We want to provide the testing component for studies, providing clinical reproducibility and consistency, and those are the things as a top-notch lab that we are interested in doing.”

With a physician-led group that has experience in molecular diagnostics, partnering with Steep Hill is about being medically focused, according to Dr. Rosenstein. “First and foremost, this is about patient safety.” Because of that, he emphasizes the need for required microbiological contaminant testing, particularly because of his experience with patients. “If you’re a cancer patient and you get a toxic dose of salmonella or E. coli, that can kill you, so testing for microbiologic contamination is of the highest priority.”
According to Warner, bridging the medical cannabis science gap with Steep Hill’s professionalism and experienced doctors practicing medicine is a big deal. “We are working very closely with their medical team to make sure these standards are medically superior,” says Warner. “To have these doctors with such a high level of knowledge in medicine working with us in cannabis analytics is a breakthrough.”
“By achieving ISO/IEC 17025 accreditation, TEQ Analytical Labs believes that we can address the concerns throughout the cannabis industry regarding insufficient and unreliable scientific analysis by providing our clients with state-required tests that are accredited by an international standard,” says Seth Wong, president of TEQ Analytical Laboratories. According to a TEQ Analytical press release, accreditation to this standard confirms that laboratories have the management, quality, and technical systems in place to ensure accurate and reliable analyses, as well as proper administrative processes to confirm that all aspects related to the sample, analysis and reporting are standardized, measured and monitored.
By implementing ISO 17025 accreditation, the laboratory monitors systems and processes central to analyses in an effort to minimize discrepancies and variability in test results. According to Roger Brauninger, biosafety program manager at A2LA, this type of accreditation demonstrates their competence and commitment to rigorous science. “It is encouraging to have testing laboratories taking ownership of the quality of the work performed,” says Brauninger. “Reliable testing will be imperative to insure safety of the products out on the market as this industry continues to expand.” As the first accreditation of its kind in North America, Brauninger hopes this will open the doors for more cannabis laboratories to acknowledge their role in demonstrating scientific competency for the industry.
Tripp Keber, president and chief executive officer of Dixie Brands, Inc., commends the achievement. “At Dixie Brands, we believe that cannabis is powerful, that quality is important, and that accurate dosing is of supreme importance,” says Keber. “Because Dixie is committed to delivering a safe, consistent, and accurately dosed product, lab testing is a vital component to our manufacturing processes.”
“TEQ’s achievement of ISO 17025 accreditation instills great confidence to Dixie Brands that our consumers’ health and safety is ensured and that they will enjoy a reliable and predictable experience with our product each and every time,” adds Keber. “Dixie’s strategic relationship with TEQ continues to build long-term brand value.” This kind of accreditation helps build trust in laboratories’ clients knowing they can provide accurate results repeatedly.
Dan Anglin, a Marine Corps veteran and chairman of the Colorado Cannabis Chamber of Commerce, is the founder and chief executive officer of Americanna, an infused products business in Colorado with a heavy focus on regulatory compliance, consistent dosing and product safety. The company was the very first to implement the THC stamp, a requirement for all infused products in Colorado this coming October 1st.
Dan Anglin, founder & CEO of Americanna
As a veteran of Operation Desert Storm, Anglin began his career as a legislative analyst in Arizona, and then moved to Colorado where he worked for the Colorado Legislative Council. Soon after, he became a lobbyist for the Colorado Association of Commerce and Industry. With a focus on health policy, he became the primary lobbyist for anything related to healthcare at the state level.
After running his own lobbying firm, he was hired by EdiPure, which was at the time the largest infused product manufacturer, to lobby against an amendment in the state legislature that would have all but shut down the infused products industry. Within six months, he was made a partner and co-owner of EdiPure for almost three years where he focused on regulatory compliance and legislative matters. In April of 2015, Anglin left EdiPure to buy Boulder Pharma with Frank Falconer, rebranding the company as Americanna making primarily edible products.
According to him, over the past few years, public opinion has grown in favor of differentiating cannabis products from other food products beyond just the packaging. Anglin said he saw this coming and embraced it as a core concept of his business model. Americanna produces gummies in the shape of a cannabis leaf with the THC stamp on each individual gummy. “This is a matter of public safety that you can clearly tell it is a cannabis product by its shape and symbol,” says Anglin. “We should be proud of cannabis products as an expression of American liberty, it is our duty not to hide it in an unrecognizable food product, but celebrate it with a clear shape and stamp, providing for consumer safety.” In this Q&A, we sit down with Dan Anglin to learn about his quality and safety controls, manufacturing processes and why his business embodies American freedom.
CannabisIndustryJournal: How do you see what you are doing as exercising your American liberties?
Dan Anglin: I served my country and protected the rights of Americans overseas. Because the people of Colorado have chosen this [adult use cannabis legalization] to be a right expressed in the state constitution, I feel that every day our 38 employees come to work and make cannabis products, we are exercising our rights as citizens of Colorado and of the United States.
The Americanna Team
The adult use side of the cannabis industry is a true expression of liberty in choice. This is what freedom is all about! In the past five years, the United States has given more and more groups of people more freedoms and liberties; this is another group of people that believe they deserve rights, in this case the liberty to consume cannabis freely.
This is an issue of states’ rights too. The people of Colorado voted to make the adult use of cannabis a right in their state constitution. We are abiding by the Cole Memo by doing everything we can to protect public safety. There is still a long way to go, but the fact that my employees and I are paying taxes and selling this in a regulated environment is absolutely an expression of our American liberty.
CIJ: Walk us through some of your quality controls in manufacturing infused products.
Dan: We have a contract manufacturer with a white label agreement, so our food products are of the same quality as any food product you would find in major retailers. Quality controls begin as soon as we unpack the food product, making sure it has been stored at the right temperature with all of the right conditions. We toss any products that do not meet our quality standards. Post-infusion, we go into packaging and separate them into flavors. As packagers are putting them into the child resistant packaging as required by law, they are doing QC checks on every single gummy.
The most important part of our quality control system is the testing for potency, homogeneity and microbial contamination. Post-harvest, the cannabis is tested and after it is extracted, the product is tested again but this time also for residual solvents. Once we infuse the product, we test it again. This is so important because making any type of food product requires doing everything you can to prevent bacterial contamination.
CIJ: How do you view cannabis safety as your responsibility?
Dan: Frank and I developed the business based on compliance and consistency. We already comply with rules expected to be enforced six months from now. We want consumers to be able to count on the consistency of the dosing in our products. Our semi-automated process of infusion can precisely dose every single product to ten milligrams. It is an infusion that soaks through the product, not a spray, and is one of the most homogenous products available.
Because we are creating food products, we have the same responsibility as any other food producer. When you make something that people ingest, it is your responsibility to follow health codes that provide guidelines for food handling. Every one of my employees is ServSafe certified. We are treating cannabis as an ingredient in a food product. Food safety is paramount and should be at the top of every infused product manufacturer’s mind.
Derek Peterson, chief executive officer of Terra Tech
Terra Tech, with the recent acquisition of Blum, a dispensary in Oakland, and the line of concentrates, IVXX, is sweeping the cannabis industry by setting standards for safety and quality. Terra Tech, publicly traded in theOver-The-Counter market, is well known as an agricultural company, with the subsidiary brand, Edible Garden, selling produce to Whole Foods, Wal-Mart and Kroger’s. In December of last year, we covered Terra Tech’s entrance into the cannabis marketplace and their experience with large-scale, sustainable agriculture. We sit down with Derek Peterson, chief executive officer of Terra Tech, to get an update on their progress and quality controls.
CannabisIndustryJournal: In January, Terra Tech announced revenue guidance of $20-22 million for 2016. Can you share some of your strategy going forward to meet your goals?
Terra Tech is taking organic and GFSI-certified agricultural practices to growing cannabis
Derek Peterson: We have always played both a long game as well as a short game, meaning while we are building our longer term business, like in Nevada, we are also focusing on short term accretive acquisitions, like we did with Blum in Oakland. We want to make sure we capture short-term revenue growth while we plan our future revenue production. We feel confident about achieving those results.
CIJ: How big of a role does the acquisition of Blum and IVXX brand expansion play in meeting those goals?
The Oakland location of Blum dispensary
Derek: Blum is a significant factor even though we are only capturing three quarters of revenue considering we closed the deal on March 31st of this year. So for the full year of 2017 we will have growth from this level considering we will be able to report a full year of Blum revenue. IVXX presents us with the best opportunity for growth in the coming years. As the market in California and Nevada grows we can continue to expand our IVXX footprint throughout the state. Being able to wholesale to thousands of other retail facilities affords us a significant opportunity to grow our sales.
CIJ: How do you think the brand of Edible Garden positions you well for expansion in the cannabis industry?
Produce ready for distribution at Edible Garden facility in Belvidere, New Jersey
Derek: One of the reasons we were so successful in the Nevada market was because regulators and legislators felt a high degree of confidence in our abilities considering we are USDA organic, Kosher and GFSI-certified. Our traditional agricultural experience has been very synergistic with our cannabis division from both an optics and operational perspective.
CIJ: Could you give us an update on progress in Medifarm LLC in Nevada? And on your distribution plan for IVXX in California?
IVXX concentrates
Derek: We are continuing to expand our IVXX line throughout the state and increasing our sales force. In addition we will continue to develop new products to distribute into our existing supply chain, like we just did with our new pre filled cartridge line.
We are opening our Decatur location in Las Vegas in early July and Reno and Desert Inn towards the end of August. Our cultivation and extraction facilities should be complete no later than January 2017. We will have our entire infrastructure in place if the recreational bill passes in Nevada this November.
Blum Las Vegas location will open in July
CIJ: Tell us about the role of laboratory testing in your business.
Derek: Laboratories play a significant role, as they are becoming a mandated step in most new legislation around the company. Independent lab testing is extremely important to maintain safe access for consumers and patients. We work primarily with Steep Hill Labs and CW analytics.
CIJ: Can you expand on your integrated pest management and your growing practices?
Platinum Cookies ready for packaging and labelling
Derek: Well we cannot say organic, however we do cultivate all naturally. We also cultivate traditional produce that we sell to major retailers. We are USDA organic-certified and we implement similar processes in our cannabis cultivation. Pest control is extremely challenging for any farmer but we rely primarily on bio control, meaning the good bugs eat the bad bugs. This has been very effective for us in the cultivation of all our products.
CIJ: How is your business different from the slew of other dispensaries and growers in California?
Consistency in quality standards requires meticulous SOPs
Derek: Service and consistency; we have over 42,000 registered patients and our operations team has over 19 years of experience in California. One of the reasons we have become one of the largest dispensaries in the state is because of that experience. In addition, consistency is extremely important. Consumers expect the same product in every other business and ours is no different. If they come in for our Platinum Cookies one month and the next month it has different characteristics you are going to lose patient confidence. So in the front of the house, we are focused on pairing patients’ needs with the correct product and in the back of the house we are focused on providing a meticulously cultivated product, produced at the highest standards.
CIJ: Can you delve into some of the processing for concentrates? How do you meet such rigorous quality standards?
Extraction equipment in one of the processing facilities for IVXX
Derek: Through research and development, we have engineered a proprietary process in which our solvent profiles used under our proprietary conditions ensures solvent residual levels which are not detected by instrumentation at 3rd party testing agencies such as Steep Hill Labs. In addition, any good scientific method requires repetition and corroboration of results. In order to accomplish this we also rely on random routine testing in which we send out extracts out to other 3rd party testing labs. Proprietary conditions include, but are not limited to, heat, vacuum, agitation, etc. By utilizing the correct amalgamation of solvent profiles, extraction conditions, purging conditions, as well as rigorous quality control standards, we are able to ensure a product that is void of any residual solvents, without sacrificing potency or identity of the cannabinoids and terpenes. Cannabinoids and terpenes are of chief interest when extracting cannabis for patients so that they have access to these essential oils without any of the actual leaf and bud.
All solvents used are the highest grade available to us, which ensures a truly medical product for the patient. In addition, all of our extraction equipment is routinely cleaned and sterilized using medical grade cleaning agents.
