Give a Voice to Scientists in the Executive Suite

By Dr. Markus Roggen, Amanda Assen

What do Aurora Cannabis, Tilray and Pfizer all have in common? They all produce and sell products used for medicinal purposes, they are top competitors in their field and they all have statements on their websites claiming that science is one of the most important things to their business. But unlike Pfizer, Aurora and Tilray do not have any positions in the executive suite for scientists or medical personnel. This led us to wonder, why does the structure of their corporate ladder (as well as so many other cannabis companies) not align with what they claim to be their values?

According to Aurora Cannabis, “Science is at the core of what we do”.1 Look up the definition of “core” and you will get “foundational, essential, central, and enduring.”2 Sounds important. Meanwhile, Tilray’s main page states: “For the therapeutic value and risks of cannabinoid-based medicines to be fully understood, Tilray believes it is critical to evolve current scientific understanding of the field.”3

aurora logoYou would assume that somebody in the executive suite would have a position and an educational background relating to the central and enduring part of a business, right? We looked at 10 of the biggest Canadian cannabis companies, their founders’ educational backgrounds and whether there were executive positions for science, R&D or medicine (Table 1). We also looked at the same data for the top 10 biggest pharmaceutical companies (Table 2). As expected, every pharmaceutical company had upper-level (C and/or P level) positions for scientists and/or medical personnel. However, only 2 of the 10 cannabis companies had this.

tilray-logoTo figure out why this is, (as scientists) we did some research. It turns out, the consensus is scientists are bad at commercialization. Scientists are rarely successful as CEOs because they are (usually) not good at attracting customers and get confused by things like revenue models.4 As Akshat Rathi bluntly put it, “just because you are the smartest person in the building does not make you capable to run a company.” In fact, many CEOs of life science companies got to the top by pursuing business, finance, marketing or sales. In the 90s, some life science companies took a chance on scientists and hired them as CEOs, but when they hit financial turmoil, they quickly undid this.5

So maybe scientists aren’t always cut out to be the CEO of a company. But that still doesn’t explain why so few large cannabis companies have a chief scientific/medical officer, or even a president of R&D.

Maybe we are looking in the wrong place. Maybe their value of science can be demonstrated by their spending on research. Typically, a larger agricultural company will spend 9% or more on R&D, and a smaller company will spend 2-4%.6 Meanwhile, the major pharmaceutical companies we looked at spent between 12 and 25% of their revenue on R&D during their most recent fiscal year. Since a cannabis company falls somewhere in between we approximate they would spend around 9-12%.

Canopy_Growth_Corporation_logoHowever, Canopy Growth was the only company that fell into our prediction range, spending 10.5% of their revenue on R&D in 2021.7 Tied for a distant second place were Charlotte’s Web and Aurora Cannabis (a subsidiary of Tilray), spending 4.6%. At the very bottom were Tilray which only spent 0.16% on R&D and TerrAscend which spent 0.21% during their most recent fiscal year.8,9 With most of the cannabis companies, we saw a gradual decrease in R&D funding over time, which intensified with the Covid-19 pandemic.

So why the heck are these companies going on about how they value science? To give them the benefit of the doubt, maybe they do think they value science, but they don’t know how to value it.

 It’s hard for a company to take actions that show they value science if there are no voices for scientists at the executive level. After all, how can you make decisions based on science if nobody in the room understands it? Sure, we saw the argument that people who make it to the top can “learn enough science to ascend to the executive suite without much trouble”.5 But what is “enough science”? The mitochondria is the powerhouse of the cell?

This leads to our argument for putting scientists in the executive suites of cannabis companies and giving them a more powerful voice. Whereas scientists are not good at marketing, those in managerial roles tend to overly rely on intuition – even when the evidence is against them.10 For those relying on intuition, R&D is an easy target during times of crisis (like a global pandemic). Cutting costs in R&D yields a short-term immediate increase in profit and the negative impacts are often not felt until years later.11 However, cutting R&D investment is the opposite of what you should do during a time of crisis. Evidence suggests companies that maintain or even increase spending in marketing and R&D and focus on operational efficiency (such as process optimization) are the ones that will come out as the top competitors in the long run.12,13 Having a chief scientific officer or an executive for R&D with a scientific background can help sustain companies by promoting R&D during hard times and indicating what projects will be the most promising to help the company optimize their processes.

Having a scientist in the executive suite can also help keep everyone in check. “Senior execs live in a feedback loop of positive reinforcement making them unlikely to question their decisions,” according to Stefan Thomke and Gary Loveman.10 They claim the best way for those in managerial roles to avoid over relying on instinct and break out of that positive feedback loop is by “thinking like a scientist”. This involves not letting bias get in the way of truth, studying anomalies, being skeptical, developing strong hypotheses, producing hard evidence and probing cause and effect. To add to this, we think a major part of thinking like a scientist is by having at least one high up in the team. In our own company, giving equal value to scientific voices has resulted in all parties learning and thriving by making fact-based decisions.

Finally, scientists deliver! To be a scientist (with a PhD), one must master the field, find a gap in the knowledge, then fill that gap – all for little pay and no guarantee of a job at the end. This makes them dedicated workers whose main goal is to contribute something unique to their field, or in this case, their company.14 Having someone up top who is dedicated, passionate, innovative and trained to look for gaps in knowledge can be an invaluable voice in the executive suite. They are likely to point out potential money-saving solutions (i.e.: optimizing extraction conditions) that others up top may not have thought of on their own.

If you feel strongly that science is at the core of what you do, and you already know that R&D is crucial for the long-term survival of your company, you are already on the right track. In addition to this, consider giving a voice to scientists at the executive level in your company. The cannabis industry is still in its infancy. This means there is potential for R&D in more than just new product development. Basic stuff like extraction, modifying plants to be heartier against harsh conditions and pathogens, curing and safety testing processes have all barely been studied and optimized to reduce costs. These things won’t be solved by a Juris Doctor, an MBA or even an engineer, they will be solved by scientists, and it will take a scientist up top to ensure the whole company recognizes the importance of these projects.

The Hopes of Illinois Social Equity Applicants

By Taneeshia Thomas
4 Comments

It is almost impossible to turn on the tv and not find a show or news conference or even live footage of an ongoing protest over “Black Lives Matter” or “Economic Equality.” The same situation exists with social media platforms, radio broadcast, etc. All sharing the common theme of social equity. While we all seek a solution, the state of Illinois is doing their part by awarding the coveted adult use cannabis business licenses for craft growing, infusion, transportation and dispensaries to social equity applicants by using a scoring system that favors the social equity applicant. We believe in this vision at TGC Group and our dream is to pay it forward.

Taneeshia Thomas and her husband, Christopher Lacy, who did 3.5 years in prison for growing cannabis in 2009.

We see the world, especially for minorities living in poverty, quite differently because of where we come from. “Black Lives Matter” is a movement to save the lives of all people and have human life viewed equally no matter the race of an individual. Economic equality is a totally different fight. Our communities that are impoverished need cash infusions. There needs to be financial infrastructure that recirculates the dollars from the poor communities and that comes from having business owners in the affected community to put their profits back into their community. There needs to be a system of lending that is not based on credit scores and criminal background checks because most people at the bottom will never qualify. An example would be my husband, Christopher Lacy: he went to prison for 3.5 years for growing cannabis back in 2009. He is not a violent man; he never even had a fight in prison. He spent much of his time in prison teaching inmates how to read, write and most importantly, he tried to teach them economics. He is educated about cannabis because he has been intimately involved with this plant and has been growing it for just about 20 years. Yet when he tried to apply for jobs in Illinois for growing cannabis, his invisible barrier starts with the resume. Just think about it, my husband, knows more about cannabis than most people in the industry today and could manage a facility with ease. No one could see his worth because of his background and work experience? This is the same situation with so many others in our poor communities. We know for a fact that there is hidden talent in the impoverished communities and prison system, and we intend to find it and empower these individuals to rebuild what was destroyed by the war on drugs. I speak for all the ghettos when I say this: give us access to the capital and we will get the rest done on our own. Conventional banks have their hands tied with this approach because they are regulated, but private funds have more flexibility. The excess capital needed to rebuild will not come from jobs, it only comes from ownership. Luckily, J.B. Pritzker and Toi Hutchinson are aware of this and hence created the social equity fund to help the social equity applicants fund their projects if and when they are awarded a license. We must find a way to give to the bottom so that the dollars can trickle up. Trickledown economics is kind of like that movie “Platform” on Netflix. There are never enough resources to get to the bottom because the people sending the resources down have no idea how to get them to the bottom floors of society. Trickle up economics can start at the very bottom rungs of society and still will reach to this highest level of the economic system because its built in such a way that it will inevitably get there.

State Sen. Toi Hutchinson (D-Park Forest), now The Illinois Cannabis Regulation Oversight Officer

These new licenses, literally pathways to financial freedom if operated correctly and efficiently, are revenue machines capable of changing our community. This change does not come from providing jobs (although jobs do help and will be available), but by providing capital to rebuild. These funds can provide scholarships, business loans, even small infrastructure projects can get accomplished via the tax revenue generated by the local governments. We have already made a written commitment to give a portion of net margins to the village. Capital in the right hands can make dreams come true. In theory, poverty can be solved. Poverty is not a prerequisite to the American way of life. That is why we were so proud to get zoning approval by our village. They see what we see. We can change neighborhoods like Beacon Hill. The dollars must recirculate in the community. Wherever you see high poverty rates you see high crime rates. This is not a coincidence. If you can lower the poverty rate you can lower the crime rates. This raises the quality of life for everyone. We see the state is on board, the county is on board, the Village of Park Forest is on board and the citizens of the community are on board. Now all we need is the license and capital to get the resurrection started.

Unlike other applicants, we were only capable of applying for one license for a craft grow facility. Some may see this as a disadvantage because only 40 licenses will be issued for this purpose. I wish we could have applied for more to increase our odds, but resources were scarce and applying was not cheap. We decided to stick with the efficient market theory and put all our eggs in the one basket that we know we can carry and be successful with. Without the help of Justice Grown, we would’ve never completed the application so shout out to them and anyone else that helped “true” social equity applicants apply.

The wheels are in motion so all we can do is wait to see who wins. I would hate to be on the team who must decide who wins these licenses. Everyone knows large corporations found ways to apply as social equity applicants because they only needed a certain number of “social equity” employees to qualify. But if you go ask the employees, not the owners, if they have been cured of their financial burdens and see if $15 has raised their quality of life to a middle-class level. The answer is emphatically NO. You cannot give out band-aids for heart attacks. If these large corporations are awarded the licenses, it will perpetuate the cycle of poverty. We do not personally have anything against the big companies. Like Toi Hutchinson said regarding the first round of dispensary and cultivation licenses: we needed the big company dollars to fund the next round of licenses. Well, the next round is here. Let’s do right by the communities that were truly affected by the war on drugs and on a more personal level and my reason for applying: let’s do right by my husband because he lost 3.5 years of his life and was excluded from participating with his family for doing what is now legal.

The Beginner’s Guide to Integrated Pest Management

By David Perkins

Formulating a Plan

In this article you will learn how to control pests and improve the health of your cannabis plants using integrated pest management, commonly referred to as IPM. This involves a multi-point strategy – there is no quick fix, nor is there one solution that will wipe out all your pest problems. Proper pest management requires patience, consistency and determination.

It is important to understand that not all pesticides are bad. While many are incredibly harmful not only to pests, but also humans, in this article I will educate you about some of the safer alternatives to traditional pesticides. It is possible to safely control unwanted pests in your cannabis garden without harming yourself, your employees or the natural habitat around you.

Every cultivation facility should have a well-thought-out plan for their pest management program. This program should account for the prevention, and if necessary, eradication of: spider mites, russet mites, fungus gnats, root aphids, thrips and caterpillars. These are just a few of the more common pests you’ll find in a cannabis garden. There could also be many other less commonly known bugs, so you have to be vigilant in looking closely at your plants, and the soil, at all times. Complete eradication of a targeted pest can be difficult. Once a pest has established itself, decimating or decreasing the population will require an aggressive regimen that includes spraying daily to control populations and prevent other pests from getting established.

Spraying or applying pesticides to the foliage of plants isn’t the only way to control or eradicate pest populations. There are many other ways that you can minimize the spread of pests without the use of pesticides. In greenhouse and outdoor grows, growing specific types of plants around the cultivation area will attract both beneficial and predator bugs that will naturally control pest populations. Some plants that attract these bugs are: mint, peppers, and marigold. Beneficial and predator bugs, such as ladybugs, predator wasps and predator mites, can control unwanted pest populations in the area before they even have a chance to become a problem in your garden. Plants and flowers that attract bees, birds and insects will also create helpful bio- diversity, making it more difficult for the unwanted pests to thrive.

For indoor cultivation, it is imperative that you have your cultivation facility set up for a proper workflow. If you already have pests, you need to make sure you are not contaminating the rest of your facility when going from one area to the next. Make sure that you only go to contaminated areas at the very end of your day, and when you’re done working in that area, you must immediately exit the building. Do not ever walk back through the uncontaminated parts of your facility or the pests will spread quickly.

An aphid on a plant in a greenhouse

When most people think of pests in their cannabis garden they think of the more common varieties: spider mites, russet mites, aphids and thrips. However, there are also soil-dwelling pests that can exist, without your knowledge. These will decrease the health and vigor of your plants, without you even knowing they’re there, if you’re not careful to check for them. Some of the soil dwelling pests that plague cannabis plants are: root aphids, fungus gnat larvae and grubs. It is just as important to control the pests below the soil, feeding on your roots, as it is to control the pests that feed above soil on your plants.

Maintaining healthy plants is essential to controlling pest populations, both on the foliage and below the soil. Healthy plants will have an easier time fighting off pests than unhealthy plants. Plants have immune systems just like humans, and the stronger the plant’s immune system, the more likely it will be able to ward off pests and diseases. Allowing a plant to reach its full potential, by minimizing pests, means your plants will also have a better quality, smell and flavor, not to mention a bigger yield.

Worker Safety, Regulation and REI times

The application of pesticides requires certification from the state agricultural department. In certain situations, depending on the type of pesticide and method of application, a license may even be required. The application of pesticides without proper certification is against the law. Applying pesticides in a manner that is not in accordance with the label and instructions is also a violation of law.

The proper personal protective equipment (PPE) is required for anybody handling, mixing or applying pesticides. Employees can be a liability to your company if they are applying pesticides improperly. Make sure you and your entire staff are well educated about pesticide use requirements and limitations, prior to usage, and that only a properly certified person is handling the mixing and application at your facility.

The author, David Perkins, In his greenhouse after using insect killing soap.

After a pesticide is applied, you must abide by the re-entry interval (REI). This is the required time period limiting all workers from re-entry into areas where pesticides have been applied. This time period will vary depending on the type of pesticide used and the method of application. In some instances, pesticides applied in the last 30 days may require employee training before work can be done in those areas.

The misuse of or improper handling of pesticides is not only unlawful and dangerous to human health, but can also cause environmental damage to waterways and wildlife. The direct effects of pesticides on wildlife include acute poisoning, immunotoxicity, endocrine disruption, reproductive failure, altered morphology and growth rates and changes in behavior. Pesticides can indirectly impact wildlife through reduction of food resources and refuses, starvation due to decreased prey availability, hypothermia and secondary poisoning. Section 1602 of the California Fish and Game Code governs requirements for permitting of any project where pesticides will be used, and strictly regulates the disposal of all waste and run-off. It is imperative to know the regulations and to abide by them, or heavy fines will ensue!

Using Pesticides in a Regulated Market

Knowing which pesticides you can’t use, to avoid failing mandatory state testing, is just as important as knowing which ones you can use safely to pass required testing. Most states with regulated markets have strict limitations on the pesticides that can be used in cannabis cultivation. Pesticide use in the cultivation of cannabis is the most strictly regulated in the agriculture industry; the pesticides allowed for use in cannabis cultivation are far more limited than any other crop.

Just because a product is certified organic does not mean that it can be used, or that it is safe to be consumed or ingested. Oftentimes when cannabis flower alone is tested it will not fail or show a detectable amount of pesticides or heavy metals. However, when that flower is turned into concentrates, banned substances are then detected in testing, leading to test failures.

Cannabis cultivation facilities that are located on land that was previously used for conventional agriculture, or located near vineyards or other agricultural crops that are heavily sprayed with harmful pesticides, run a very high-risk failing testing. This is because of either spray drift from nearby agriculture, or residual pesticides and heavy metals left in the soil from previous crops that were using pesticides banned for cannabis cultivation. Accordingly, if you’re going to be growing outdoors or in a greenhouse, it is imperative that you get a soil and water test prior to cultivation, so you can determine if there is any potential for test failures due to pesticides or heavy metals in the soil or water in that area. 

Proper Application – Using the Right Tools in the Right Way at the Right Time

One of the most important factors in pest management is proper identification of pests and proper application and coverage of pesticides. It does not require an entomology degree to identify insects, these days there is a lot of information online that can help you identify cannabis pests. Proper identification of insects can make the difference between success and failure. With a good eye and a microscope, if you do your research, you can control most insects in your garden.

In order to control pests in your garden you must get proper coverage of the foliage of the plant when you are applying pesticides. There are different types of equipment that are commonly used to apply pesticides in cannabis cultivation: backpack sprayers, foggers, and airless paint sprayers are the most common. An alternative method involves using an automated dosing system such as a dosatron, which injects fertilizer or pesticides at a specific ratio into your water lines, allowing you to use only the exact amount of pesticide you need. That way you avoid wasting money on unused pesticides. It is also safer for employees because it minimizes employee exposure, since there is no mixing required, and it allows for a large volume to be sprayed, without refilling a tank or a backpack sprayer.

No matter what you are using you must ensure you get the proper coverage on your plants in order to control pests. The temperature and humidity of your cultivation area, as well as the PH and temperature of the pesticide solution, all factor into the success of your IPM. For example, PFR 97 needs to be applied at a higher humidity range, around 70% to be most effective. In some areas this is not possible so repeated applications may be required to ensure the application is effective. A high PH or alkaline PH can cause alkaline hydrolysis which will make your pesticide solution less effective and will dictate how long your pesticides remain effective after they are mixed. It is therefore important to use your pesticide solution as soon as you make it; don’t let it sit around for long periods of time before use or it will be less effective.

In cannabis cultivation there are two different primary growth cycles: vegetative and flower. These cycles require different IPM strategies. In general, during the flowering cycle, pesticides should not be applied after the second week, with some limited exceptions i.e. for outdoor cultivation there is a longer window to spray since the flower set takes longer than a plant being grown inside, or in a light deprivation greenhouse, where there is a 12/12 flowering cycle.

Starting with an immaculate vegetation room is crucial to maintaining pest and mold free plants in the flowering cycle.

For the vegetative (non-flowering) cycle, a strict rotation of foliage spray applications targeting not only pests, but also molds and pathogens, will be necessary to avoid a quick onset of infestation. Starting with an immaculate vegetation room is crucial to maintaining pest and mold free plants in the flowering cycle. Preventative sprays that are safe for use include: safer soap (contact kill) for soft bodied chewing insects; Regalia (biological control) for powdery mildew; and PFR 97 (biological control) for soft bodied chewing insects. It is also helpful to spray kelp, which strengthens the cell walls of plants, making the plant healthier, and thus enabling the plant to better defend itself from pests and diseases. Also, Bacillus thuringiensis (Bt) is useful to prevent or kill caterpillars.

The best way to control a pest infestation in the flowering cycle is at the very beginning on day one. You must start aggressively, with a three-way control consisting of a contact kill and preventative during days 1-14; preventative and biological control during days 10-18; and then release predator bugs on day 25, for optimal results. Knocking back the population with an effective contact kill pesticide early on is essential to ultimately lowering populations throughout the grow cycle, so that you can spray a biological control to preclude them from returning, before you release the predatory bugs at the end of the cycle.

Biological controls can take anywhere from 3 to 10 days before they are effective. Biological pesticides are selected strains of bacteria or fungus. When the plant tissue is eaten by a targeted pest, the bacteria kills the pest from the inside providing control without having to spray pesticides repeatedly. Predator bugs are the last line of defense, used in late flowering. They can be used indoors, outdoors and in greenhouses. An example of a common predator bug is Amblyseius californicus used to control low populations of spider mites, but there are many different varieties and they are specific depending on the type of pest population you seek to control.

A common concern with the use of predatory bugs, is whether they will be present when the flowers are harvested. However, if there is no food for the bugs (i.e. pests) the predator bugs will leave in search of food elsewhere. Further, indoor predator bugs are usually very small in size and difficult to see to an untrained eye. It is very unlikely to see any signs of predator bugs near the end of the flowering cycle, or in the finished flower product. Even when using bigger predator bugs, the bugs will leave the plants when harvested and dried.

Having pests can be very stressful. It is not uncommon to have bugs, pests, rodents, animals and birds cause damage in cannabis gardens. Making an informed decision based on science and not on unproven assumptions can determine how successful you are at pest management. There are many factors that go into pest management and no one situation is the same. You must be dedicated and consistent; pest management never stops. You will always have something ready to invade your garden. Prepare, plan, prevent and repeat!

Khiron Life Sciences Makes Strategic Moves In South America

Khiron Life Sciences Corp. has played an interesting game globally for some time now. Far from a “high flier” in the first tiers of Canadian cannabis companies to watch, that may be changing. Not to mention, this fall, what exactly do these labels mean right now as almost all the first movers retrench and reconsider?

How and where Khiron’s influence will be felt however, is still very much a question in the air.

The big news? The company has obtained authorization from the Colombian government to commercialize high-THC cannabis, and further, for both domestic and international consumption.

There are several interesting things about this announcement.

The first is that Khiron inevitably got its domestic license to supply a 15,000-patient trial “at home” in Columbia (and for the prestigious Latin American Institute of Neurology and the Nervous System).

The second is that the company will also be exporting – and to where.

Uruguay is at the top of that list – starting with the fact that the country has had a “recreational market” that actually predates Canada’s. To import medical cannabis here in other words, is also an interesting statement in and of itself. Namely, what is wrong with domestically produced Uruguayan product? Even and especially in this case, for the medical market? (The answer of course has more to do with U.S. banking law than product quality).

The second is the UK where the company will also supply the patient trial there – Project Twenty21. This is even more intriguing considering that the NHS has just denied the efficacy of cannabis for treating neurological conditions and pain and only recently agreed that Sativex was “cost effective” after negotiating a lower bulk price with GW Pharmaceuticals made possible by the new NICE guidelines.

The third is Brazil – a growingly valuable market now firmly on the radar of those watching all things cannabis-related in the hemisphere.

Regardless, it shows that the lights are on in the executive suite at Khiron. The question is, will this early mover advantage pay off – and more interestingly, where?

A Hemispheric Play – But In Which Long Term Direction?

While the UK at least seems to be Brexiting itself off a cliff of free trade agreements with the world (and expect cannabis to be in the early room of conversation about commodities in this regard), is Latin American cannabis really price impactful in low price per gram Europe long term? Especially given the inclinations of a company whose CEO admits in press statements that he wants to be a “Starbucks of Cannabis” – selling not coffee beans at “80 cents a pound…” but rather a cup of coffee “for four dollars.”

That is a still-to-be answered question. Especially in an environment where the German government has announced its essential reference wholesale price for floss at €2.30 per gram (around four dollars American). Not to mention what is going on domestically in countries across the continent from Denmark and Portugal to Poland.

However, what all this positioning also does of course, is pose questions for Khiron’s intentions throughout the American hemispheres, both more locally and of course north of the Rio Grande (in the U.S. market) not to mention Canada.

This is the kind of reverse hemisphere play of course that everyone in North America has been expecting since Uruguay’s early market movement earlier in the decade. The great South American fruit and veg market is finally allowed to turn to legal production in the form of cannabis.

Is the “Drug War” finally in its last, dying days? The answer appears to be yes. Trade wars, inevitably, however, are looming. Protectionism in the cannabis industry may be a new flavour of the day but not in any other agricultural or indeed any other kind of commodity. And on this front, things are also likely to be fierce.
