According to a press release sent out last week, Complex Biotech Discovery Ventures (CBDV) has expanded their testing capabilities considerably with the new addition of a vapor/smoke analyzer. CBDV is a licensed cannabis and psilocybin research laboratory embedded in the University of British Columbia, led by CEO Dr. Markus Roggen.

The ability to analyze vapor and smoke is a relatively novel concept for the cannabis space, but has been utilized by the tobacco industry for years now. In the early days of adult-use cannabis legalization in the United States, stringent testing regulations for contaminants like pesticides were adopted out of a fear for what would happen when consumers ingest toxic levels of contaminants.

One of the common refrains iterated throughout the industry over the past ten years was that there just wasn’t enough research on how different contaminants affect patients and consumers when burned and inhaled. We still don’t know too much about what happens when someone smokes a dangerous pesticide, such as myclobutanil. Beyond just contaminants, the new technology allows for companies to measure precise levels of cannabinoids in vapor and smoke, getting a more accurate reading on what cannabinoids are actually making it to the end user.

This new development coming from our neighbor to the north could lead to a breakthrough in the cannabis lab testing and research space. CBDV claims they can now analyze cannabis material with a much more in-depth analysis than basic compliance testing labs. The new technology for analysis of smoke, vapor, plant material and formulations allows companies to thoroughly understand their materials in each stage of the product formulation process, all the way to product consumption.

Beyond just smoke and vapor analysis CBDV also offers NMR spectroscopy, metabolomics, nanoparticle characterization, computational modeling and other testing services that go far beyond the traditional compliance testing gamut.

“Our new services offer comprehensive insights into plant material, extracts, end-products and even the smoke/vapor by using state-of-the-art analytical instruments,” says Dr. Roggen. “By understanding the chemical fingerprint of the material, cannabis producers can eliminate impurities, adjust potencies, and optimize extraction processes before wasting money and resources on producing inconsistent end products. As a chemist I am really excited about adding NMR and high-res mass spectroscopy to the cannabis testing offerings.”

Heat-Not-Burn: A Q&A with Mike Simpson, CEO and Co-Founder of Omura

Heat-not-burn is a non-combustion technology consisting of a heating source and either an oven that the user packs cannabis into or a stick pre-filled with cannabis. The cannabis is heated to a lower temperature than a combusted joint or bowl to create an aerosol that the user inhales. Heat-not-burn in this way is distinct from traditional vaping where a liquid or oil is heated to become a vapor and inhaled.

Omura is a design company that has developed a platform product for the heat-not-burn market.

We spoke with Mike Simpson, CEO and co-founder of Omura. Mike co-founded Omura in 2018 after an international design career where he spent much of his time in Japan working with consumer products.

Aaron Green: Mike, what trends are you following in the market?

Mike Simpson: I’m always tracking trends in the heat-not-burn space. Because of my background, I know that the tobacco industry inspires a lot of the technology in the cannabis space. If you look at all the vape pens, that technology was initially developed for big tobacco, which then later was adopted by cannabis. I’m always looking to stay educated on what’s happening in the tobacco industry, as I know it’s directly tied to my work in cannabis.

I’m also looking at what’s happening all over the world with legislation. I’ve been studying it for years, but this past year has been phenomenal. Seeing five new states go to some level of legalization, the federal law and new states legalizing cannabis in the 2020 Election. I believe the Biden/Harris victory will have a major impact on the industry, however we still have to see what happens with the Senate. These next couple of years are going to be very interesting to see how things shape out for cannabis.

Aaron: What are you personally interested in learning more about?

Mike Simpson, CEO and co-founder of Omura

Mike: I am interested in learning how the world is going to behave next year with this new life that’s been thrusted upon us. How effective is the new vaccine going to be? How are people going to retrospectively look at this year, and the lifestyle that they used to have before going into COVID? How much of it’s going to become permanent? How much of this Zoom life will we continue to enjoy? In the future, will office spaces become obsolete? How much will we still be using home deliveries? Do we actually want to go to restaurants again? That’s what I’m very interested in learning about is how human behavior and the world will change because of what’s happening right now.

Aaron Green: How did you get started at Omura?

Mike Simpson: Great question. I moved to Japan as a designer working for Lego and set up their design office for Lego toys. After Lego, I started working instead with Nike and Adidas designing performance sneakers and apparel for a couple of years until I found Big Tobacco — which is where my Omura story begins. I rapidly found myself in a position where I was creating new technologies, for the consumption of nicotine and tobacco. While working on an early project, I was asked if I knew any science fiction writers. Thanks to Lego, I just so happened to know Syd Mead, the designer for popular sci-fi films including BladeRunner, Tron and Aliens. So, I called him and we worked on a project which was aimed at setting the future of the smoking industry. Obviously, this was a brilliant project for someone like myself to get involved in. We came up with several scenarios that depicted the future of what tobacco consumption would look like, and each of them essentially included vaporization. This was before the vaporization days which made it kind of a difficult sell. I spent many years working on where we could use existing technologies in order to execute some of these scenarios. Ten years later, I moved to California, and I started studying the cannabis space for Big Tobacco which ultimately led me to Omura.

Aaron: Can you give me a reference point on the date when you were back in California?

Mike: I came here eight years ago, and I was in Japan pretty much 10 years prior to that.

Essentially what I realized when I got to California was that cannabis was perfect for heat-not-burn because of all the cannabinoids and the terpenes. You heat it up, and you get all of the good properties out of it without the need for combustion. There were already hundreds of products in the market, which validated that people love doing it.

However, there was a ritual: you needed to buy the flower, grind it, pack the device, select the temperature and then use the same mouthpiece repeatedly. And it doesn’t stop there. When the session is finished, you dig out the used flower with a metal spatula or brush. After every 10 or 15 times you have to clean it with rubbing alcohol to get rid of any existing residue from those sessions. This is just a big messy job with a massive amount of inconsistency and variability. For me, it was mind blowing that people would even go through this procedure. With Omura, I knew we needed to simplify that process. Our product comes with a pre-filled flower stick with an exact dose, that you place in the device very simply. You then use the stick as the mouthpiece and when you’re finished, throw the flower stick in the trash. It’s compostable and biodegradable. So we eliminated all of those pain points.

Aaron: Great! Where are you guys based out of?

Mike: Venice, California.

Aaron: So, what makes the Omura vaporizer different from other heat-not-burn products? You mentioned you have the disposable cartridge. Is there a design philosophy around it that you can talk more about?

Mike: Omura comes with 12 flower sticks in child-proof packaging. What makes us different is that we have our proprietary flower stick and device that work together. With our heat-not-burn technology, you get all the terpenes, but when you set fire to it, as you would with other products, you mask that with smoke. Our product is different from anything else in the market, because it has simplified the user experience through efficiency, user interaction and also through design as well.

The other founders come from deep design and technology backgrounds, designing technologies for Apple and Philips Electronics, so it was an important focus for us with Omura. Our newest device, the Series X was designed by Michael Young, a world-renowned industrial designer who has built an impressive portfolio of innovative products.

The Omura Series X

With Omura, we’re bringing sophistication of the design world into the cannabis world. It’s not just about simplifying the experience and making a great kind of efficient method of consumption, it’s also about creating something for everyday use that is beautifully designed and easy to use.  

Aaron: The Series X is Omura’s latest device. Can you tell me what changes you’ve implemented to make it better than the first version?

There are a few differences between the Series 1 and Series X: First, the new design fits in the palm of your hands so it’s discreet. It comes with a USB-C charging base that automatically connects with magnets. We’ve also improved the efficiency of the oven. The first device boiled 94% of the cannabinoids, this one now boils 99%. We’ve increased user-efficiency, by removing the button from the Series 1 making it so all you have to do is put the flower stick in and the device starts automatically. Additionally, we wanted to give users an option between a hotter or cooler experience so we added an extra heat curve, as we recognize that some of our CBD users prefer more of a terpene experience.  

Aaron: Can the user modify that with an app?

Mike: It is a very simple switch on the bottom of the device that allows you to toggle between the higher and lower temperature curves

Aaron: Okay, cool. Can we talk about your supply chain a little bit here? Do you manufacture everything in Los Angeles? Or do you have partners? 

Mike: Everything is designed in the US and manufactured in China. Which is fairly common throughout the industry. Shenzhen is well known for making products for the vaping industry. We create empty tubes filled in a batch production process. All the flower is grown here in the US. To clarify, we aren’t a plant-touching company. We don’t have a cannabis license. When it comes to THC, we have partnership deals. We work with select cannabis brands which is how we are able to sell in dispensaries. On the other hand, our CBD model is split. We have two brands of our own. Libertine, which is more of a male-focused Gen Z brand. Then we have Oriel, which is more of a wellness brand, catered to women.

Aaron: So how would an aspiring brand get on your platform?

Mike: Good question. Any brand or company who is interested in partnering with Omura can contact us through our website, www.omura.com, on Instagram @Omura or via email: hello@omura.com. We would then assess them to see if they’re a good fit. Currently we’re looking to span quite a large kind of demographic as far as appeal. So, if these prospective partners are in a territory, whether it be California or another state, have good market share and high-quality flower, then we would be very open to having a conversation.

Aaron: That’s the end of the interview — thanks Mike!

I Was Wrong… und das ist auch gut so!

By Dr. Markus Roggen

I was wrong. And that’s a good thing! Based on all available data, I assumed that evaporating ethanol from a cannabis oil/ethanol solution would result in terpene loss. As it turns out, it doesn’t. There are so many beliefs and assumptions about cannabis: Cannabis cures cancer!1 Smoking cannabis causes cancer!2 Sativas help you sleep; Indicas make you creative!3,4 CBD is not psychoactive!5 But are these ‘facts’ backed by science? Have they been experimentally tested and validated?

I postulated a theory, designed experiments to validate it and evaluated the results. Simply putting “cannabis backed by science” on your label does not solve the problem. Science is not a marketing term. It’s not even a fixed term. The practice of science is multifaceted and sometimes confusing. It evolved from the traditional model of Inductivism, where observations are used in an iterative process to refine a law/theory that can generalize such observations.6 Closely related is Empiricism, which posits that knowledge can only come from observation. Rationalism, on the other hand, believes that certain truths can be directly grasped by one’s intellect.7 In the last century, the definition of science was changed from the method by which we study something, such as Inductivism or Rationalism, and refocused on the way we explain phenomena. It states that a theory should be considered scientific if, and only if, it is falsifiable.8 All that means is that not the way we study something is what makes it scientific, but the way we explain it.

I wonder how can we use empirical observations and rational deliberations to solve the questions surrounding cannabis? And more importantly, how can we form scientific theories that are falsifiable? Cannabis, the plant, the drug, has long been withheld from society by its legal status. As a result, much of what we know, in fact, the entire industry has thrived in the shadows away from rigorous research. It’s time for this to change. I am particularly concerned by the lack of fundamental research in the field. I am not even talking about large questions, like the potential medical benefit of the plant and its constituents. Those are for later. I’m talking about fundamental, mundane questions like how many lumens per square centimetre does the plant need for optimal THC production? What are the kinetics of cannabis extraction in different solvents? What are the thermodynamics of decarboxylation? Where do major cannabinoids differ or align in terms of water solubility and viscosity?

The lack of knowledge and data in the cannabis field puts us in the precarious position of potentially chasing the wrong goals, not to mention wasting enormous amounts of time and money. Here’s a recent example drawn from personal experience:Certainly, I cannot be the only one who has made an incorrect assumption based on anecdotes and incomplete data?

Some of the most common steps in cannabis oil production involve ethanol solutions. Ethanol is commonly removed from extraction material under reduced pressure and elevated heat in a rotary evaporator. I expected that this process would endanger the terpenes in the oil – a key component of product quality. My theory was that volatile terpenes9 would be lost in the rotary evaporator during ethanol10 removal. The close values of vapor pressure for terpenes and ethanol make this a reasonably assumed possibility.11 In the summer of 2018, I finally got the chance to test it. I designed experiments at different temperatures and pressures, neat and in solution, to quantify the terpene lost in ethanol evaporation. I also considered real life conditions and limitations of cannabis oil manufacturers. After all the experiments were done, the results unequivocally showed that terpenes do not evaporate in a rotary evaporator when ethanol is removed from cannabis extracts.12 As it turns out, I was wrong.

We, as an industry, need to start putting money and effort into fundamental cannabis research programs. But, at least I ran the experiments! I postulated a theory, designed experiments to validate it and evaluated the results. At this point, and only this point, can I conclude anything about my hypothesis, even if that is that my working theory needs to be revised. Certainly, I cannot be the only one who has made an incorrect assumption based on anecdotes and incomplete data?

There is a particular danger when using incomplete data to form conclusions. There are many striking examples in the medical literature and even the casual observer might know them. The case of hormone replacement therapy for menopause and the associated risks of cardiovascular diseases showed how observational studies and well-designed clinical trials can lead to contradicting results.13 In the thirties of the last century, lobotomy became a cure-all technique for mental health issues.14 Dr. Moniz even won the Nobel Prize in Medicine for it.15 And it must come as no surprise when WIRED states “that one generation’s Nobel Prize-winning cure is another generation’s worst nightmare.”16 And with today’s knowledge is impossible to consider mercury as a treatment for syphilis, but that is exactly what it was used as for many centuries.17 All those examples, but the last one in particular should “be a good example of the weight of tradition or habit in the medical practice, […] of the necessity and the difficulties to evaluate the treatments without error.”18 There is the danger that we as cannabis professionals fall into the same trap and believe the old stories and become dogmatic about cannabis’ potential.

We, as an industry, need to start putting money and effort into fundamental cannabis research programs. That might be by sponsoring academic research,19 building in-house research divisions,20 or even building research networks.21 I fully believe in the need for fundamental cannabis research, even the non-sexy aspects.22 Therefore, I set up just that: an independent research laboratory, focused on fundamental cannabis research where we can test our assumptions and validate our theories. Although, I alone cannot do it all. I likely will be wrong somewhere (again). So, please join me in this effort. Let’s make sure cannabis science progresses.
