Illinois Raises Over $10 Million of Tax Revenue in January

After just one month of legalized recreational cannabis, Illinois is already seeing a massive return on their investment. According to the Chicago Sun Times, Illinois has raised roughly $10.4 million in tax revenue from their newly legal market ($7.3 million in cannabis tax revenue and $3.1 million in retails sales tax revenue).

When Illinois Governor J.B. Pritzker first announced their estimated budget before the market was legalized, he predicted that Illinois would generate about $28 million in tax revenue in the first six months. The totals from January more than doubling the predicted per month revenue indicates that his office’s estimates were significantly lower than reality.

Illinois Governor J.B. Pritzker

In total, dispensaries in the state did just under $40 million in sales in January, which makes it the second-largest first month rollout in the country. For reference, Illinois did $39.2 million total sales in their first month which, whereas Nevada took the #1 spot with $39.8 million.

About 35% of the tax revenue that Illinois generates will be used in the state’s general revenue fund, 10% will be spent on previous expenses, 25% goes to the Restore, Reinvest and Renew Program, an initiative for unemployment and preventing violence and recidivism, and the last 30% of that revenue goes towards mental health services, substance abuse services, public education and awareness campaigns as well as a police grant program.

Toi Hutchinson, senior adviser on cannabis control to Governor J.B. Pritzker, told the Chicago Sun Times that the tax revenue from legalization is to be spent on social equity and helping communities adversely impacted by the war on drugs. “Revenue raised in this first month will soon begin flowing back into those communities to begin repairing the damage done by the failed policies of the past and creating new opportunities for those who have been left behind for far too long,” says Hutchinson.

The Illinois Hemp Industry Is About To Explode

Within two days of announcing the opening of license applications for growing hemp, the Illinois Department of Agriculture received roughly 350 applications. According to the Lincoln Courier, that number has since grown to 575 applications in the past couple weeks. The Illinois Department of Agriculture has already issued 341 licenses for growing and 79 for processing, as of last Friday.

According to Jeff Cox, Chief of the Bureau of Medicinal Plants at the Illinois Department of Agriculture, a lot of this excitement comes from farmers wanting to branch out from the state’s traditional crops, such as corn and soybeans. “Corn and soybean prices have not been the best over the past few years, and so I think they see this as an opportunity to have a different source of income on their farm,” Cox told the Lincoln Courier.

Morgan Booth, spokeswoman for the Illinois Department of Agriculture told the Chicago Tribune that they were expecting this kind of enthusiasm among farmers. “We knew there was a lot of interest in it,” says Booth. “We were very pleasantly surprised.”

Back in late December of 2018, after the Farm Bill was signed into law, the Illinois Department of Agriculture was quick to jump on the hemp train. They announced their intentions to submit plans for a program to the federal Department of Agriculture, opened a 90-day public comment period, and finalized the rules in April. The state’s regulators hoped to expedite the process and have farmers growing hemp by June 1, which appears to be successful. Dozens of hemp farmers throughout the state are anticipating their first crops will be in the soil by the end of the month.

Stratos: Quality, Expansion & Growth in Multiple Markets

By Aaron G. Biros

Jason Neely founded Stratos in 2014, when he and a small group of people left the pharmaceutical industry in search of a new endeavor in the cannabis marketplace. The concept was straightforward: Apply pharmaceutical methodologyof production to cannabis products. Back then, Stratos offered a range of THC-infused tablets in the Colorado market.

Brenda Verghese, vice president of research & development

Brenda Verghese, vice president of research & development, was one of five people on staff when Stratos launched. Now they have about 30 team members. Consumers were looking for a cannabis product that would be consistent and reliable every time, taking the guesswork out of infused products dosage. That’s where Brenda Verghese found her skillset useful.

Transitioning to the pharmaceutical industry right out of college, Verghese started her career as a chemist and worked her way up to the R&D business development sector. “I specializedin formulations and taking a product from concept to commercialization in the pharmaceutical space,” says Verghese. “Jason Neely approached me with the idea of a cannabis company and focusing on making products as effective and consistent as possible, so really bringing pharmaceutical science into the cannabis space. In the matter of 4 years we grew substantially, mainly focusing on the efficacy of products.”

Soon after the success of their THC products became apparent, Stratos launched a CBD line, quickly growing their portfolio to include things like tinctures and topicals as well. According to Verghese, they are hoping that what’s been established on the THC side of their business as far as reproducibility and consistency is something that consumers will also experience on the CBD side. “Quality and consistency have definitely driven our growth,” says Verghese. “That is what consumers appreciate most- the fact that every tablet, tincture or swipe of a topical product is going to be consistent and the same dose every time.” This is what speaks to their background in the pharmaceutical sciences, FDA regulation has taught the Stratos team to create really robust and consistent formulations.

Quality in manufacturing starts at the source for Stratos: their suppliers. They take a hard look at their supply of raw materials and active ingredients, making sure it meets their standards. “The supplier needs to allow us to do an initial audit and periodic audits,” says Verghese. “We require documentation to verify the purity and quality of oil. We also do internal testing upon receipt of the materials, verifying that the COAs [certificates of analysis] match their claims.”

Verghese says maintaining that attention to detail as their company grows is crucial. They implement robust SOPs and in-process quality checks in addition to process testing. They test their products 5-6 times within one production batch. Much of that is thanks to Amy Davison, director of operations and compliance, and her 15 years of experience in quality and regulatory compliance in the pharmaceutical industry.

Back in August of 2018, Amy Davison wrote an article on safety and dosing accuracy for Cannabis Industry Journal. Take a look at this excerpt to get an idea of their quality controls:

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.

Fast forward to today and Stratos is looking at expanding their CBD products line significantly. While their THC-infused products might have a stronger brand presence in Colorado, the CBD line offers substantial growth potential, given their ability to ship nationwide as well as online ordering. “We are always evaluating different markets and looking for what suits Stratos and our consumer base,”says Verghese.

Spotlight on AOAC: New Leadership, New Initiatives In Cannabis & Food

By Aaron G. Biros

AOAC INTERNATIONAL is an independent, third party, not-for-profit association and voluntary consensus standards developing organization. Founded in 1884, AOAC INTERNATIONAL was originally coined the Association of Official Agricultural Chemists. Later on, they changed their name to the Association of Official Analytical Chemists. Now that their members include microbiologists, food scientists as well as chemists, the organization officially changed its name to just AOAC INTERNATIONAL.

Much of AOAC’s work surrounds promoting food safety, food security and public health. Their work generally encompasses setting scientific standards for testing methodology, evaluating and adopting test methods and evaluating laboratory proficiency of test methods. The organization provides a forum for scientists to develop microbiological and chemical standards.

In December of 2018, they appointed Dr. Palmer Orlandi as deputy executive director and chief science officer. Dr. Orlandi has an extensive background at the U.S. Food and Drug Administration (FDA), serving the regulatory agency for more than 20 years. Most recently, he was the CSO and research director in the Office of Food and Veterinary Medicine at the FDA. He earned the rank of Rear Admiral and Assistant Surgeon General in 2017.

Dr. Palmer Orlandi is the new Deputy Executive Director and Chief Science Officer at AOAC.

Where It All Began With Cannabis

As recently as three years ago, AOAC began getting involved in the cannabis laboratory testing community, with a working group dedicated to developing standard method performance requirements for AOAC Official MethodsSM for cannabis testing. We sat down with Dr. Palmer Orlandi and a number of AOAC’s leaders to get an update on their progress working with cannabis testing as well as food security and food fraud.

According to Scott Coates, senior director of the AOAC Research Institute, they were approached three years ago to set up a working group for cannabis testing. “We created standards that we call the standard method performance requirements (SMPR®), which are detailed descriptions of what analytical methods should be able to do,” says Coates. “Using SMPRs, we issued a series of calls for methods and looked for methods that meet our standards. So far, we’ve completed four SMPRs- cannabinoids in plant material, cannabinoids in plant extracts, cannabinoids in chocolate (edibles), and one for pesticides in cannabis plant material.” AOAC doesn’t develop methods themselves, but they perform a comprehensive review of the methods and if they deem them acceptable, then the methods can be adopted and published in the AOAC compendium of methods, the Official Methods of Analysis of AOAC INTERNATIONAL.

Deborah McKenzie, senior director of Standards and Official Methods at AOAC

Deborah McKenzie, senior director of Standards and Official MethodsSM at AOAC, says the initial working group set the stage for really sinking their teeth into cannabis testing. “It started with methods for testing cannabinoids in plant dried material and plant extract,” says McKenzie. “That’s where our previous work has started to mold into the current effort we are launching.” McKenzie says they are looking forward to getting more involved with methods regarding chemical contaminants in cannabis, cannabinoids in various foods and consumables, as well as microbial organisms in cannabis. “We are pretty focused on testing labs having reliable and validated analytical solutions as our broad goal right now.”

Moving Forward, Expanding Their Programs

Coates says the work they’ve done over the past few years was more of a singular project, developed strictly for creating standards and to review methods. Now they are currently developing their Cannabis Analytical Science Program (CASP), which is expected to be an ongoing program. “We are looking to fully support the cannabis analytical community as best we can, which will potentially include working on reference materials, proficiency testing, education, training and ISO 17025 accreditation, all particularly as it applies to lab testing in the cannabis industry,” says Coates. “So, this CASP work is a much bigger and broader effort to cover more and to provide more support for labs doing the analysis of cannabis and its constituents, as well as hemp.”

According to Dr. Orlandi, they want this program to have a broad reach in the cannabis testing community. “As Scott pointed out, it’s not just strictly developing standards and methods,” says Dr. Orlandi. “It is going to be as all-encompassing as possible and will lead to training programs, a proficiency testing program and other areas.” Arlene Fox, senior director of AOAC’s Laboratory Proficiency Testing Program, says they are actively engaging in proficiency testing. “We are in the process of evaluating what is out there, what is possible and what’s needed as far as expanding proficiency testing for cannabis labs,” says Fox.

Regulatory Challenges & Obstacles

The obvious roadblock to much of AOAC’s work is that cannabis is still considered a controlled substance. “That creates some challenges for the work that we do in certain areas,” says Dr. Orlandi. “That is why this isn’t just a one-year project. We will work with these challenges and our stakeholders to address them.” AOAC had to put some limits on participation- for example, they had to decide that they cannot look for contributions or collaborations with producers and distributors, so long as cannabis is still a Schedule I controlled substance in the US.

Arlene Fox, senior director of AOAC’s Laboratory Proficiency Testing Program

Muddying the waters even further, the recent signing of the Farm Bill puts a clear distinction between most types of cannabis and industrial hemp. David Schmidt, executive director of AOAC realizes they need to be realistic with their stakeholders and in the eye of federal law.

While scientifically speaking, it’s pretty much the same plant just with slightly different chemical constituents, AOAC INTERNATIONAL has to draw a line in the sand somewhere. “As Palmer suggests, because of the Farm Bill being implemented and hemp being defined now as a legal substance from a controlled substance standpoint, industrial hemp has been given this exclusion,” says Schmidt. “So, we are trying to be realistic now, working with our stakeholders that work with hemp, trying to understand the reality of the federal law. We want to make clear that we can meet stakeholder needs and we want to distinguish hemp from cannabis to remain confident in the legality of it.” Schmidt says this is one of a number of topics they plan on addressing in detail at their upcoming 9thannual 2019 Midyear Meeting, held March 11-14 in Gaithersburg, Maryland.

Uniformity in Methodology: The Future of Cannabis Testing

Dr. Orlandi says his experience at the FDA has prepared him well for the work being done at AOAC. “The role that I served at the FDA prior to joining my colleagues here at AOAC was very similar: And that is to bring together stakeholders to accomplish or to solve a common problem.” Some of their stakeholders in the CASP program include BC Testing, Inc., the Association of Food and Drug Officials (AFDO), Bia Diagnostics, Bio-Rad, Industrial Laboratories, Materia Medica Labs, PerkinElmer, R-Biopharm AG, Supra R & D, TEQ Analytical Laboratories, Titan Analytical and Trilogy Analytical, among others.

David Schmidt, executive director of AOAC

“The underlying reason behind this effort is to create some level of harmonization for standards and methods,” says Dr. Orlandi. “They can be used in the near future to stay ahead of the curve for when regulatory agencies become involved. The idea is that these standards for analytical methods will already be established and as uniform as possible.”

When comparing cannabis to other industries in the US, Scott Coates mentions that most standards are signed off by the federal government. “When we started looking at pesticides in cannabis, it became really clear that we have a number of states doing things differently with different limits of quantification,” says Coates. “Each state, generally speaking, is setting their own standards. As Palmer was saying, one thing we are trying to do with this CASP program eventually will be to have some harmonization, instead of 30 different states having 30 different standards and methods.” So, on a much broader level, their goal for the CASP program is to develop a common set of standard methods, including hemp testing and even the Canadian market. “Hopefully this will be an international collaboration for standards for the methodology,” says Coates. They want to create a common set of standards, setting limits of quantification that will be accepted internationally, that will be accurate and repeatable and for the entire cannabis industry, not just state by state.

Food Authenticity & Fraud

One of the other activities that AOAC just launched recently is the food authenticity and fraud program. As the name implies, the goal is to start developing standards and methods and materials to look at economically adulterated foods, says Dr. Orlandi. That includes non-targeted analyses looking at matrices of food products that may be adulterated with an unknown target, as well as targeted analytes, identifying common adulterants in a variety of food products. “One example in the food industry is fraudulent olive oil,” says Dr. Orlandi. “Honey is another commodity that has experienced adulteration.” He says that in most cases these are economically motivated instances of fraud.

AOAC INTERNATIONAL is working in a large variety of other areas as well. All of these topics will be explored in much greater detail at their upcoming 9thannual 2019 Midyear Meeting, held March 11-14 in Gaithersburg, Maryland.

Pesticide Testing: Methods, Strategies & Sampling

By Charles Deibel
No Comments

Editor’s Note: The following is based on research and studies performed in their Santa Cruz Lab, with contributions from Mikhail Gadomski, Lab Manager, Ryan Maus, Technical Services Analyst, Dr. Laurie Post, Director of Food Safety & Compliance, Andy Sechler, Lab Director, Toby Astill, Senior Business Development Leader at Perkin Elmer and Charles Deibel, President of Deibel Cannabis Labs.


Pesticides represent the leading cause of batch failures in the cannabis industry. They are also the hardest tests to run in the laboratory, even one equipped with state-of-the-art equipment. The best instruments on the market are HPLC and GC dual mass spectrometer detectors, called “HPLC-qqq”, “GC-qqq,” or just triple quads.

As non-lab people, we envision a laboratory that can take a cannabis sample, inject it into a triple quad and have the machine quickly and effortlessly print out a report of pesticide values. Unfortunately, this is far from reality. The process is much more hands on and complex.In the current chemistry lab, trained analysts have to first program the triple quads to look for the pesticides of concern; in cannabis pesticide testing, this is done by programming the first of two mass spectrometers to identify a single (precursor) mass that is characteristic of the pesticide in question. For BCC requirements in California, this has to be done for all 66 pesticides, one at a time.

Next, these precursor ions are degraded into secondary chemicals called the “product” ions, also called transition ions. The second of the two mass spectrometers is used to analyze these transition ions. This process is graphed and the resulting spectrum is analyzed by trained chemists in the lab, pesticide by pesticide, for all the samples processed that day. If the lab analyzes 10 samples, that translates to 660 spectra to analyze (66 pesticides x 10 samples). When looking at the spectra for each pesticide, the analysts must compare the ratios of the precursor ions to the product ions.

Confirmation Testing

If these spectra indicate a given pesticide may be present, the chemists must then compare the ratios between the precursor and the products. If these ratios are not what is expected, then the analyst must perform confirmation testing to prove the precursor mass either is or is not the pesticide of concern. If the ratios are not what is expected, it means the molecule is similar to the pesticide in question, but may not be that pesticide. This confirmatory testing is key to producing accurate results and not failing batches when dealing with closely related chemicals. This process of analyzing spectra is done in all labs that are performing pesticide testing. In this fledgling industry, there are few published cannabis pesticide methods. 

The need for this type of confirmation testing doesn’t happen all of the time, but when it does, it will take longer than our targeted three-day turn-around time. In the picture above, one precursor mass is ionized into several product masses; but only two are large enough to be used for comparison. In this hypothetical situation, two product masses are produced for every one precursor, the expected ion abundance ratio should be less than 30%. When performing any confirmatory testing, if the ion abundance ratio is >30%, it means the original precursor molecule was not the pesticide of concern. For example, if the ion abundance ratio was 50%, then the original molecule broke down into too many parts; it was not the pesticide we were looking for. This ion abundance ratio threshold was established by FANCO, the international organization that sets guidelines for all pesticide testing.

Testing Strategies

Methodology: In this fledgling industry, there are few published cannabis pesticide methods. The identification of the precursor mass and product ions are not always published, leaving labs to research which ions should be used. This adds to the potential for differences between lab results. Once selected, labs should validate their research, through a series of experiments to ensure the correct precursor and transition (product) ions are being used in the method.

Sample Preparation: Beyond the time-consuming work that is required to develop sound pesticide methods, the extraction step is absolutely critical for credible results. If the pesticides aren’t fully extracted from the cannabis product, then the results will be lower than expected. Sample preparations are often not standardized between labs, so unless a given extraction technique is validated for accuracy, there is the possibility for differences between labs.

Getting a Representative Sample

The current California recommended amount of sample is one gram of product per batch. Batch sizes can vary greatly and it is entirely likely that two different one gram samples can have two different results for pesticides. Has the entire plant been evenly coated with exactly the same amount of pesticide onto every square inch of its leaves? No, probably not. That is why it is imperative to take a “random” sample, by taking several smaller samples from different areas of the entire batch.

Sampling Plans: We can learn a lot from the manufacturing and sampling best practices developed by the food industry through the years. If a food manufacturer is concerned with the possibility of having a bacteria pathogen, like Salmonella, in their finished product, they test the samples coming off their production lines at a statistically relevant level. This practice (theory) is called the sampling plan and it can easily be adapted to the cannabis industry. The basic premise is that the more you test, the higher your likelihood of catching a contaminate. Envision a rectangular swimming pool, but instead of water, it’s filled with jello. In this gelatinous small pool, 100 pennies are suspended at varying levels. The pennies represent the contaminates.

Is the pool homogenized? Is jello evenly represented in the entire pool? Yes. 

Is your concentrate evenly distributed in the extraction vessel? Yes. The question is, where are the pennies in that extraction vessel? The heavy metals, the microbial impurities and the pesticides should be evenly distributed in the extraction vessel but they may not be evenly represented in each sample that is collected. Unfortunately, this is the bane of the manufacturing industry and it’s the unfortunate reality in the food industry. If you take one random cup of jello, will you find the penny? Probably not. But it you take numerous 1 cup samples from random areas within the batch, you increase your chances of finding the contaminate. This is the best approach for sampling any cannabis product.

The best way to approve a batch of cannabis product is to take several random samples and composite them. But you may need to run several samples from this composite to truly understand what is in the batch. In the swimming pool example, if you take one teaspoon scoop, will you find one of the pennies? The best way to find one of the pennies is to take numerous random samples, composite them and increase the number of tests you perform at the lab. This should be done on any new vendor/cultivator you work with, in order to help establish the safety of the product.
