Cannabis brands are facing a proverbial fork in the road: determining whether their product evolves into a luxury consumable or affordable agricultural commodity. While it is reasonable to assume the cannabis market space will organically grow into a luxury goods industry such as wine and spirits, the luxury brands that serve as the foundation of these markets were built over years of engagement between consumers, connoisseurs and producers. If cannabis companies want to successfully market their products as luxury items, a concerted effort towards well-defined, consumer-accessible branding is required.
The first step towards evolving a cannabis brand towards luxury is overcoming the fixation on cultivar identity. Unregulated cultivar naming currently impedes creativity and craftsmanship, disrupting brands and salespersons’ abilities to clearly communicate strain aesthetics.
The good news is the alcohol, coffee and consumer packaged food (CPG) industries have done most of the heavy lifting, paving the way with robust sensory science and analytical approaches to product characterization. Cannabis stakeholders need only adapt their tools and apply them to cannabis with similar intention.
Research suggests that aroma is one of the strongest predictors of positive consumption experience. As adult use consumers become familiar with current product offerings and increasingly legal availability, they will seek products that consistently yield the best experience. The most successful brands will be those that most effectively communicate that experience and then deliver it. The status quo – describing aroma using strain names, top terpenes or THC content – is not effective at harmonizing a brand’s promise with consumer experience.
Figure 1: Illustration of both the conventional branding approach (top) and the sensory-based branding opportunity (bottom).
The conventional cannabis product branding approach leaves to be desired a tremendous opportunity to characterize cultivars (Figure 1). Sensory science, the discipline used to evoke, measure, analyze and interpret reactions to materials through human perception, has been used for decades to characterize CPGs from skin lotion to washing machines. Adapting these well-established techniques for use in cannabis can be challenging, but it is certainly worth the investment.
These shifts in the cannabis industry have already begun to occur. I recently was the principle investigator on a white paper that presented a novel cannabis aroma wheel derived from aroma descriptors and a panel of trained sensory experts. In the study, sensory scientists evaluated randomly sampled cannabis flower over a period of several months. The researchers combined qualitative focus panels, literature review and formal blinded sensory tests to develop a comprehensive lexicon that served as a tool for trained evaluators to characterize cannabis aroma. This novel and robust tool (Figure 2) was designed to be used by trained panels to characterize cannabis aroma, is freely available and is just the beginning of a collective development of a data-driven cannabis lexicon.
Much like the World Coffee Research Lexicon referenced here, the Cannabis Aroma Lexicon is a tool with a specific purpose: collecting an objective description of the product aroma. It is a living document that will grow along with the industry. In the future, we may have lexicons to describe more than just aroma. Tactile and appearance sensory attributes of cannabis will gradually be defined by sensory scientists, presenting more opportunities for deep craftsmanship in the cannabis industry.

The role that dispensaries play in adoption of standardized quality metrics is critical. The product features that position cannabis to be a craft product warrant the presence of a third-party expert to translate and guide consumers during the purchasing process. It’s intuitive to ask a waiter to recommend a pairing (i.e., a dry red wine to pair with a seafood dish), given the trust that consumers put in the restaurant to understand the properties of the food they are serving. Dispensaries have thus far filled the service structure role for cannabis, but the vast amount of unknowns regarding the physiological and sensorial effects of cannabis have resulted in inconsistent experiences that leave something to be desired in terms of consumer trust.
Application of sensory science in cannabis is an unparalleled opportunity for brands to build consumer trust and differentiate their products in a sea of strain names and high potency flower. Cultivars that can be established as measurably aromatic in a specific character can leverage that aroma profile to add significant value to the product. For example:
Cultivar name can be aligned with the perceived aroma (e.g., garlic is not bad, but expecting tropical and getting garlic can harm consumer trust).
Product catalog can be consolidated and optimized to avoid sales cannibalization by growing specific products to meet consumer group’s needs.
Guesswork is removed from breeding by measuring when a product is meeting sensory goals and ensuring it doesn’t drift over time.
Demonstrating transparency will win over ethical consumers. Utilizing controlled, blinded studies to profile aromas will add value to ethics-minded consumers.
Becoming a leader in connoisseurship. In the forefront of this shift in branding, one can position a brand to be ahead of the competition.
Elevating the dispensary experience. By utilizing aroma profiling, products can be more easily sold by budtenders and salespeople.
Opening doors to new application types (e.g., seasonal, occasion centered or geographically unique cultivars).
These are just some of the ways that aroma characterization will differentiate products and simultaneously contribute to cannabis brands’ ability to communicate craftsmanship and the maturity of the industry as whole. Not only will adoption of robust sensory-based branding improve the consumer experience by providing a means to compare products to one another, it will promote adoption of good manufacturing practices that simultaneously improve the quality and safety of cannabis products. Without consumer-accessible quality metrics, brands have little incentive to produce products of elevated quality and are conversely incentivized to prioritize quantity and meet minimum regulatory requirements.
Importantly, cannabis businesses will use this tool to adapt to an inevitable industry-wide shift towards connoisseurship and application of robust sensory science. While it may be challenging to shake off the “bad habits” that currently plague many brands, cannabis has significant potential as a luxury good. Consumers are eager for a better cannabis experience from purchase to consumption. How will your brand use sensory profiling to expand or evolve product offerings to succeed in a cannabis market full of luxury brands and what steps will you take now to prepare?
The scent of pine from your Christmas tree. The fragrance of a ripe summer peach at the farmer’s market. The whiff of eucalyptus and lavender that greets you when you enter a spa.
Aroma is a keystone in how we experience the world. In any given environment, aroma can help shape your mood, solidify memories and instantly transport you to another place or time.
I have focused my career on studying the fascinating compounds that are often behind these powerful aromas: terpenes. They form the largest class of natural products (compounds produced by living organisms), found in nearly all living beings. There are around 50,000 currently known terpenes in nature — with potentially thousands yet to be discovered.
Terpene-rich plants you might be most familiar with are lavender, mint, oranges (in the peel), and yes, cannabis. In recent years, terpenes have rightfully become a central discussion in the recreational cannabis world. This is because terpenes — not THC level, not “Indica-Sativa” classification — are a key determinant of cannabis’s effect, both psychoactive and non-psychoactive. But the current lack of prioritization and understanding of the crucial role terpenes play may put the collective quality of U.S. cannabis at risk.
At this crucial inflection point for legal cannabis, on its path to becoming a $70 billion dollar global industry by 2028, we need to ensure that everyone across the cannabis space, from breeders to testers, growers and consumers, understands which traits to prioritize for a cannabis world brimming with diversity and predictable effects.
What the cannabis industry has to lose
What do we lose if the cannabis industry continues to scale without a clear understanding of the compounds that define the uniqueness of each variety?
There is a ripple effect across the ecosystem. For cannabis testing labs, focusing on only twenty of the most dominant terpenes means we are missing out on tapping into potentially over a hundred of less common terpenes in cannabis. For the cannabis consumer, lack of understanding on the breeding and testing side may make it difficult to find cannabis that delivers on its promised effect time and time again. And, most detrimentally for breeders, not understanding the direct correlation between genetics and the formation of terpenes means we will have increasingly fewer terpene profiles and combinations to work with, especially when the industry-dominant focus has been on cannabinoid potency.
Let’s explore some misconceptions related to potency. In recent years, many breeders have prioritized high THC levels over genetic diversity. Consumers often associate high THC levels and that telltale strong “skunky” aroma with a strain’s quality and effect, when in reality, these are poor indicators of potency. (In fact, recent research indicates that this specific cannabis aroma is caused by a family of sulfur compounds.) Terpene profiling is a much more accurate way to determine a variety’s given effect. In focusing too much on increasing THC, breeders miss out on the true potency powerhouse: tapping into the terpene diversity that’s out there.
Terpenes are responsible for giving flowers (including cannabis), fruits and spices their distinctive flavors and aromas. Common terpenes include limonene, linalool, pinene and myrcene.
To illustrate the impact of breeding practices that prioritize crop yield over product quality, I first have a question for you: When was the last time you enjoyed a really good tomato?
If you’re lucky enough to have a great farmer’s market nearby, maybe you purchased an heirloom tomato at peak freshness last August. It was likely fragrant, flavorful and didn’t need much preparation to be enjoyable.
Or maybe you can’t remember the last time you’ve eaten a good tomato, as the last standard grocery store tomato you purchased was watery, tasteless and essentially scentless.
Tomatoes are a prime example of what is unfortunately true for a whole host of traditional crop plants in the U.S. When yield is the goal, flavor and aroma profiles often suffer. The culprit: lack of genetic diversity in the breeding process. The tragedy of the tomato serves as a harbinger for the cannabis industry — and we can draw parallels to what we’ve seen happen to cannabis.
What the cannabis industry should do: Tap into the diversity that’s out there
An important aspect of preventing cannabis from going the way of the tomato is to better understand the genes that generate these different terpene profiles. Different cultivars with varying aromas will hold different collections of genes. We as an industry must learn more about which terpenes correlate with desirable aromas, and then access already existing genetic diversity.
We have just begun to scratch the surface of the potential of terpenes in cannabis. With the right alignment across the industry and a stronger focus on genetics in breeding, we will see the rise of completely unique cannabis varieties. They will smell like lavender, lilac, orange peel or even brand-new aromas that have yet to be discovered. To ensure this future, we need to prioritize the right traits and the right genetics.
This is the second piece in a two-part conversation with the founders of Veda Scientific, CEO Leo Welder and CSO Aldwin M. Anterola, PhD. To read part one, click here.
In part one, we chatted about their backgrounds, their approach to cannabis testing, their role in the greater industry and how they came into the cannabis industry.
In part two, we’re going down a few cannabis chemistry rabbit holes and realizing that what we don’t know is a lot more than what we do know. Join us as we delve into the world of volatile compounds, winemaking, the tastes and smells of cannabis, chicken adobo and much more.
Aaron: Alright so you mentioned the GCxGC/MS and your more advanced terpene analysis. How do you envision that instrument and that data helping your customers and/or the industry?
Leo: Some of the things that we envision will help is a better understanding of what compounds and what ratios will lead to desirable outcomes, things like better effects, aroma and flavor. By better understanding these things it’ll help the industry create better products.
I have a personal connection to this. My wife has some insomnia and she’s always had to take various forms of OTC pharmaceuticals to help with sleep. She tried using a 1:1 vape pen and it was a miracle worker for her for several months. The local dispensary had a sale on it, and she bought some extra. Unfortunately, even though she used it the same way as before, she got very serious anxiety, which obviously didn’t help her sleep. Every time she used the vapes from this same batch, she felt the same extreme anxiety. Sadly, she now had a lot of this product that she couldn’t use because it kept her awake rather than helping her sleep, so she went back to trying other OTC solutions. That’s a problem for both consumers and the industry at large. If people find something that works and provides a desired effect, they need to be able to rely on that consistency every time they purchase the product, leading to similar outcomes and not exaggerating the problem. That’s why I think consistency is so important. We’re taking two steps forward and one back when we have inconsistent products. How do we really grow and expand the availability of cannabis if we lose trust from our consumer base? What a lab can do and what we can do is provide data to cultivators and manufacturers to create that consistency and ultimately allow the market to expand into other demographics that are currently wary and less tolerant of that variance.
Vials of cannabis samples being prepped for collaborative research with the CESC
On a similar note, we have been having a lot of discussions with the CESC [Clinical Endocannabinoid System Consortium] down in San Diego. They are an advanced cannabis research group that we have been working with for over a year. We’ve started looking at the idea of varietals. To be more specific, because I’m not a wine connoisseur, varietals are the pinot noirs, the cabernets and sauvignon blancs of the industry. In the cannabis industry, consumers have indica and sativa, though we still argue over what that concept really means, if anything. But for the sake of argument, let’s say we have this dichotomy to use as a foundational decision tool for consumers- call it the red and white wine of the cannabis industry. How inaccessible would wine be if we just had red or white? Imagine if you went to a dinner party, really liked the wine you were drinking, and the host could only tell you that it was a red wine. You can’t go to a wine store and expect to find something similar to that wine if the only information you have is “red.” At a minimum, you need a category. So that’s what varietals are, the categories. The data that we can produce could help people in the industry who identify and establish the varietals based on their expertise as connoisseurs and product experts to find what those differences are chemically. Similarly, we’re also looking at appellation designations in California. So, we want to help provide tools for farmers to identify unique characteristics in their flower that would give them ability to claim and prove appellation designation.
Aldwin: The GCxGC/MS allows us to find more things besides the typical terpene profile with 20 or 40 terpenes. It allows us to go beyond those terpenes. The issue sometimes is that with a typical one-dimensional GC method, sure you could probably separate and find more terpenes, but the one dimension is not enough to separate everything that coelutes. And it’s not just terpenes. Some terpenes coelute with one another and that’s why people can see this inconsistency. Especially if you use a detector like an FID, we can see the compound limonene on the chromatogram, but there’s another terpene in there that is unknown that coelutes with limonene. So, this instrument is helping us get past the coeluting issue and solve it so that we know what peaks represent what terpenes.
The other bonus with our GCxGC/MS is that the coeluting compounds that were masked behind other terpenes are now revealed. There is a second dimension in the chromatogram where we can now detect some compounds in cannabis that would be hiding behind these large peaks if it were just a one-dimensional GC. Besides terpenes, we’ve found esters, alkanes, fatty acids, ketones, alcohols and aldehydes, as well as thiols. The terpenes are so plentiful in cannabis that these other compounds present at lower levels cannot be seen with just one-dimensional GC. There are just so many compounds in cannabis that the ones in small amounts are often masked. My analogy to highlight the importance of these minor compounds is like a dish; I am from the Philippines and I like chicken adobo. My father does it differently from my mom and someone else will do it differently in a different region. The base of the sauce is vinegar and soy sauce, but some people will do it differently and maybe add some bay leaf, garlic, pepper, or a touch of another spice. It’s still chicken adobo, but it tastes differently. Just like in cannabis, where yes, you have the same amount of THC in two different plants, but it’s still giving you a different experience. Some people say it’s because of terpenes, which is true in a lot of cases, but there are a lot of other volatile compounds that would explain better why certain dishes taste different.
2-D chromatogram showing four peaks separated by the GCxGC. With a traditional 1-D chromatogram, these peaks would coelute and not separate.
Leo: There’s been some recent developments too here that show it’s very significant. It’s like the difference between bland and spicy. And it could be the thiol. We identified a thiol in cannabis at the same time as other scientists reported an article that just came out on this subject.
Aldwin: Thiols are sulfur containing compounds that produce very powerful odors, giving cannabis the skunky smell. Skunks also produce thiols. It is very potent; you only need a little bit. It turns out that yes, that paper described thiols and we also saw them in our GCxGC/MS. These are the kinds of things that the GCxGC can show you. Those very tiny amounts of compounds that can have a very powerful impact. That’s one that we know for sure is important because it’s not just us that’s finding out that GCxGC can detect this.
Not everything is about THC or the high amount of the compounds in the flower. This paper and our concurrent findings indicated that the skunkier smelling strains contained very small amounts of thiols and you can recognize their presence quite readily. It’s not a terpene, but it’s producing a distinct flavor and a powerful smell.
Aaron: Okay, so why is this useful? Why is it so important?
Leo: I would say two things in particular that we know of that are issues currently, both related to scents. We mentioned this earlier. We do know that farmers with breeding programs are trying to target particularly popular or attractive scent profiles, whether it be a gas or fruity aroma. Right now, when they get the flower tested and review the terpene profile, it isn’t enough information to help them identify what makes them chemically distinct. We hear time and again that farmers will say their terpene profile is not helpful in identifying specific scents and characteristics. They are looking for a fingerprint. They want to be able to identify a group of plants that have a similar smell and they want a fingerprint of that plant to test for. Otherwise, you have to sniff every plant and smell the ones that are most characteristic of what they’re targeting. For larger operations, walking through and smelling thousands of plants isn’t feasible.
Once we can identify that fingerprint, and we know which compounds in which ratios are creating the targeted aroma, we can run tests to help them find the best plants for breeding purposes. It’s about reproducibility and scalability.
Another value is helping people who are trying to categorize oils and strains into particular odor categories, similar to the varietals concept we’ve been talking about. Currently, we know that when manufacturers send multiple samples of oils with the same or similar scent to be tested, the results are coming back with significantly different terpene profiles. There is not enough data for them to chemically categorize products. It’s not that their categories are wrong, it’s just that the data is not available to help them find those boundaries.
Those are two issues that we know from conversations with customers that this particular piece of equipment can address.
Aldwin: Let’s start from what we find, meaning if you are using the GCxGC/MS, we are finding more terpenes that nobody else would be looking at. We have data that shows, for example, that certain standards are accounting for 60% or so of total terpene content. So a large percent is accounted for, but there is still quite a bit missing. For some strains there are terpenes that are not in common reference standards. Being able to know that and identify the reason why we have different terpenes in here unaccounted for is big. There are other things there beyond the standard terpenes.
Dr. Anterola working with the GCxGC/MS
What excites me sometimes is that I see some terpenes that are known to have some properties, either medical or antibacterial, etc. If you find that terpene looking beyond the list, you’ll find terpenes that are found in things like hardwood or perfumes, things that we don’t necessarily associate with the common cannabis terpenes. If you’re just looking for the limited number of terpenes, you are missing some things that you might discover or some things that might help explain results.
Leo: It’s also absolutely necessary for the medical side of things. Because of the federal limitations, cannabis hasn’t been researched nearly enough. We’re missing a lot of data on all of the active compounds in cannabis. We are finally starting to move into an era where that will soon be addressed. In order for certain medical studies to be successful, we need to have data showing what compounds are in what plants.
Drs. John Abrams and Jean Talleyrand of the CESC launched the Dosing Project in 2016. They have been studying the impact of cannabis flower for indications such as pain mitigation and sleep improvement, and now more recently mood, and appetite modulation. They categorize the THC & CBD content as well as flower aroma into 3 cannabinoid and 3 odor profiles. They are able to acquire quite a bit of data about how odor correlates with the outcomes. Because they were initially limited in terms of underlying natural product content data, they contacted us when they found out we acquired this equipment in 2020, and have stated that they are certain the data we will now be producing will take their research to the next level of understanding.
Aldwin: For quality control you are looking at specific things that would reflect properties in cannabis. There should be a 1:1 correspondence between properties observed and what we are measuring. The current assumption is that the terpenes we are looking at will tell us everything about how people would like it, with regards to flavor and smell preference. But we know for a fact that the limited terpenes most labs are measuring do not encapsulate everything. So, it is important for QC purposes to know for this particular strain or product, which everyone liked, what is it in there that makes everybody like it? If you just look at the typical terpene profile, you’ll find something close, but not exact. The GCxGC/MS shows us that maybe there’s something else that gives it a preferred property or a particular smell that we can explain and track. In one batch of flower, the consumer experiences it a certain way, and for another batch people experience it another way. We’d like to be able to understand what those differences are batch to batch so we can replicate the experience and figure out what’s in it that people like. That’s what I mean by consistency and quality control; the more you can measure, the more you can see.
Aldwin: Speaking to authenticity as well, in a breeding example, some growers will have this strain that they grew, or at least this is what they claim it to be, but what are the components that make those strains unique? The more analytes you can detect, the more you can authenticate the plant. Is this really OG Kush? Is this the same OG Kush that I’ve had before? Using the GCxGC/MS and comparing analytes, we can find authenticity in strains by finding all of the metabolites and analytes and comparing two strains. Of course, there is also adulteration- Some people will claim they have one strain that smells like blueberries, but we find a compound in it that comes from outside of cannabis, such as added terpenes. Proving that your cannabis is actually pure cannabis or proving that something has added terpenes is possible because we can see things in there that don’t come from cannabis. The GCxGC/MS can be used as a tool for proving authenticity or proving adulteration as well. If you want to trademark a particular strain, we can help with claiming intellectual property. For example, if you want to trademark, register or patent a new product, it will be good to have more data. More data allows for better description of your product and the ability to prove that it is yours.
Leo: One thing that I think is a very interesting use case is proving the appellations. It is our understanding that California rolled out a procedure for growers to claim an appellation, but with strict rules around it. Within those rules, they need to prove uniqueness of growing products in specific regions. The GCxGC/MS can help in proving uniqueness by growing two different strains in two different regions, mapping out the differences and seeing what makes a region’s cannabis unique. It’s valuable for growers in California, Oregon, Colorado to be able to prove how unique their products are. To prove the differences between cannabis grown in Northern California versus plants grown along the Central Coast. And of course, for people across the world to be able to really tell a story and prove what makes their cannabis different and special. To be able to authenticate and understand, we need to have more comprehensive data about properties in those strains. It could be terpenes, it could be esters or thiols. That’s what we’re excited about.
Aaron: From your perspective, what are some of the biggest challenges and opportunities ahead for the cannabis industry?
Aldwin: Getting ready for federal legalization is both a challenge and opportunity. A challenge because when it is federally legal, there will be more regulations and more regulators. It is also a challenge because there will be more businesses, more competition, that might get into the industry. It is opening up to other players, much bigger players. Big tobacco, mega labs and massive diagnostic testing companies might participate, which will be a challenge for us.
But it’s also an opportunity for us to serve more customers, to be more established at the federal level, to move to interstate commerce. The opportunity is to be ready here and now while other people are not here yet.
Another challenge and opportunity is education. Educating consumers and non-consumers. We have to realize and accept that cannabis is not for everybody, but everyone is a stakeholder, because they are our neighbors, parents or part of the medical establishment. It would be a disservice not to educate the non-consumers.
The medical establishment, they don’t have to be consumers but they need to know about cannabis. They don’t know as much as they should about cannabis and they need to know more, like how it could affect their patients for better or for worse, so they know how to help their patients better. There could be drug interactions that could affect the potency of other drugs. They need to know these things. Educating them about cannabis is a challenge. It’s also an opportunity for us to now come in and say that cannabis is here to stay and be consumed by more and more people, so we better know how to deal with it from a medical perspective.“This bucking bronco of a growth style will throw a lot of people off. We need to figure out what we can grab on to and ride out these waves.”
Law enforcement needs to be educated too. What THC level in the blood indicates impairment? It is still a challenge because we’re not there yet, we don’t have that answer quite yet. And it’s an opportunity to help educate and to find more answers for these stakeholders, so we can have regulations that make sense.
Leo: To Aldwin’s point, the biggest opportunity comes along with federal legalization as well as expanding the customer base beyond the traditional market. Since adult use was legalized in CA, we haven’t yet seen the significant expansion of the consumer population. We’re primarily seeing a legal serving of the market that already existed before legalization.
The reality is cannabis can be used in different ways than what we think of. We know it has medical benefits and we know it is enjoyed recreationally by people looking for high THC content and the highest high. But there is also this middle ground, much like the difference between drinking moonshine and having a glass of wine at dinner. The wine at dinner industry is much bigger than the mason jar moonshine industry. That’s really where the opportunity is. What’s the appeal to the broader market? That will be a big challenge, but it’s inevitable. It comes from everything we’ve talked about today, consistency in products, educating people about cannabis, normalizing it to a certain degree, varietals and appellations.
As an entrepreneur, I’m looking at this from a business perspective. Everyone talks about the hockey stick growth chart, but it is a very wavy hockey stick. I expect to see very significant growth in the industry for a while, but it will have a lot of peaks and valleys. It’ll essentially be whiplash. We are seeing this in California right now, with sky high prices in flower last year down to bottom of the barrel prices this year. We have to all figure out how to hang on. This bucking bronco of a growth style will throw a lot of people off. We need to figure out what we can grab on to and ride out these waves. The good ones will be fun and the bad ones will be painful and we know they are coming again and again and again. That’s the biggest challenge. People say ‘expect tomorrow to look a lot like today,’ but you really can’t expect tomorrow to look anything like today in the cannabis industry. Tomorrow will be totally different from today. We need to figure out, within all this chaos, what can we hang on to and keep riding the upward trajectory without getting thrown off the bronco.
Leo Welder, CEO of Veda Scientific, founded the business with Aldwin M. Anterola, PhD in July of 2019. A serial entrepreneur with experience in a variety of markets, he came to the industry with an intrigue for cannabis testing and analysis. After teaming up with Dr. Anterola, co-founder and chief science officer at Veda Scientific, they came together with the purpose of unlocking possibilities in cannabis. From the beginning, they set out with a heavy scientific interest in furthering the industry from a perspective of innovation and research.
Through discussing their clients’ needs and understanding their complex problems, the two realized they wanted to start a lab that goes well beyond the normal regulatory compliance testing. Innovation in cannabis looks like a lot of things: new formulations for infused products, better designs for vaping technology or new blends of genetics creating unique strains, to name a few. For the folks at Veda Scientific, innovation is about rigorous and concentrated research and development testing.
With the help of some very sophisticated analytical chemistry instruments, their team is working on better understanding how volatile compounds play a part in the chemometrics of cannabis. From varietals and appellations to skunky smells, their research in the chemistry of cannabis is astounding – and they’ve only begun to scratch the surface.
In this two-part series, we discuss their approach to cannabis testing, their role in the greater industry as a whole and we go down a few cannabis chemistry rabbit holes and find out that what we don’t know is a lot more than what we do know. In part one, we get into their backgrounds, how they came into the cannabis industry and how they are carving out their niche. Stay tuned for part two next week where we delve deep into the world of volatile compounds, winemaking, the tastes and smells of cannabis and chicken adobo.
Aaron G. Biros: Tell me about how you and your team came to launch Veda, how you entered the cannabis space and what Veda’s approach is to the role of testing labs in the broader cannabis industry.
Leo Welder, CEO of Veda Scientific
Leo Welder: I’m an entrepreneur. This is my third significant venture in the last fifteen years or so. So, I was intrigued by cannabis legalization broadly, because it is such a unique time in our history. I was always interested in participating in the industry in some way, but I didn’t see where would be a good fit for me. I used to meet monthly with a group of friends and fellow entrepreneurs for dinner and discussions and one member started working on the software side of the industry. He mentioned the testing element of cannabis in one of our meetings. I latched on to that and was intrigued by the concept of testing cannabis. I began to research it and found the role that testing plays in the cannabis industry is really significant. I found out that regulators rely pretty heavily on labs to make sure that products are safe, labels are accurate and that consumers have some protections. So, I thought that this is a space that I thought I could really find a calling in.
So, from that point I knew I needed to find a subject matter expert, because I am not one. I have business skills and experience in some technical fields but I am not a cannabis testing expert by any means. So, with that I started to look at a few different markets that I thought may have opportunity for a new lab, and I came across Aldwin’s business; he had a cannabis testing lab in Illinois at that time. I reached out to him, talked to him about my vision for the space and his thoughts and his vision and we really started to come together. From there, we researched various markets and ultimately chose to approach Santa Barbara County as our first foray together into the cannabis testing market.
Aldwin M. Anterola: As Leo mentioned, he was looking for a subject matter expert and I am very much interested in plant biochemistry. Which means I like to study how plants make these compounds that are very useful to us. For my PhD [in plant physiology], I was studying how cell cultures of loblolly pine produce lignin. Our lab was interested in how pine trees produce lignin, which is what makes up wood. Wood comes from phenolic compounds. You’ve probably heard of antioxidants and flavonoids – those are phenolic compounds. After my PhD, I wanted to do something different so I decided to work with terpenes.
I picked a very important terpene in our field, an anti-cancer compound called Taxol, produced from the bark of the yew tree. You have to cut trees to harvest it. We have ways of synthesizing it now. But at that time, we were trying to figure out how the tree produces that terpene. Of course, I’m interested in any compound that plants make. My interest in terpenes led me to cannabinoids which turn out to be terpenophenolics, thus combining the two interests in my professional field.
Aldwin M. Anterola, PhD, Co-Founder and Chief Science Officer at Veda Scientific,
So that’s the scientific and intellectual side of why I became interested in cannabis, but practically speaking I got into cannabis because of a consulting offer. A company was applying for a cultivation license, wanted to have a laboratory component of their business in their application, and hired me to write that part of their application. I was very familiar with HPLC, and had a GC/MS in the lab. I also have a background in microbiology and molecular biology so I can cover every test required at that time, and I knew I could research the other analytical techniques if necessary.
So, they did not get the license, but I figured I’d take what I wrote, once I received permission, and set up an independent laboratory together. But it’s hard to run a lab and be a professor at the same time. Also, the busines side of running a lab is something that I am not an expert in. Fortunately, Leo found me. Before that, I really got excited about this new industry. The concept of cannabis being now accessible to more people is so interesting to me because of how new everything is. I wanted to be involved in an industry like this and help in making it safe while satisfying my curiosity in this new field of research. As a scientist, those are the things that excite us: the things we didn’t have access to, we can now do. It opens up a whole new room that we want to unlock. It was my intellectual curiosity that really drove me. This opened up new research avenues for me as well as other ventures if you will. How can I be more involved? I thought to myself.
SIU boasts an impressive cannabis program, thanks largely to Dr. Anterola’s work there.
Back in 2014, I introduced cannabis research to our university [Southern Illinois University] and set up an industrial hemp program, which was DEA-licensed I gathered faculty that would be interested in studying hemp and cannabis and we now have a whole cannabis science center at the university. I teach a course in cannabis biology and because I also teach medical botany to undergraduate students, I was able to introduce [premed] students to the endocannabinoid system. Anyway, I can go on and on.
Outside of that I became involved with the AOAC and ASTM, and became a qualified assessor for ISO 17025:2017. I have been a member of the American Chemical Society since 2000 but there were no cannabis related activities there yet until relatively recently. But when they had the new cannabis chemistry subdivision, I am happy to participate in there as well . There are many avenues that I took to begin dabbling with cannabis, be it research, nonprofits, teaching, testing and more. Cannabis has basically infiltrated all areas of what I do as an academic.
Leo: I read his resume and I was like this is the guy! So back to your question, what’s Veda’s role as a testing lab in this space? What are we trying to build? We spent a lot of time trying to figure out what we wanted to be in this space. We came to understand that labs are not the tip of the spear for the market; that would be the growers, the retailers and the processors. We are a support, a service. We see ourselves as a humble, but competent guide. We provide the data for the tip of the spear, the people pushing the industry forward with support, data and the services to make sure they have the tools they need to build these great companies and great products with good cultivation practices and more, leading everyone to the next level of the cannabis industry. Our job is to support innovation, to provide quality compliance testing, to of course ensure safety, while also providing great R&D to these innovative companies.
Aldwin: I’d like to add a bit to that thought. Okay so that’s who we are, but what are we not? Because as Leo said I had a testing lab before we met [Advanced Herbal Analytics]. From there, I approach it as safety testing, making sure that before it gets to the end consumer, we are sort of like gate keepers keeping consumers safe. That’s one side to it, but we are not the people who are trying to make sure that none of the products get to the market. For some, that’s how we’re treated as.
People often look at testing labs like the police. We are not the people trying to limit products to market. Our approach is not to find faults. There is another way of being a testing lab that is less about finding faults in products and more about finding uniqueness. What makes your product different? With this new approach, we are much more focused on helping the best products make it to the shelves.
Aaron: Given that all state licensed labs have to provide the same tests as the other labs in that state, how does Veda differentiate itself?
Leo: Location was the first thing. We picked Santa Barbara County intentionally. We knew that some of the biggest operators, some of the most forward-thinking innovators were setting up shop here. Looking down the road, not just this year or next year but very long term, we wanted to start building a great, sustainable company. We wanted to build a brand that those kinds of companies would be receptive to. Building better and greater products. There’s one other lab in the county and that’s it. Whereas there are clusters of labs in other parts of the state. Part of the draw to Santa Barbara for us was that it is such a small, tight-knit community. We have worked very hard to build relationships in our community and to understand their challenges, helping them however we can.
Location and relationships. Getting to know the challenges that different size customers face, be it our greenhouse customers versus outdoor customers, or large-scale operations versus smaller manufacturing operations, the challenges are all different. Some people care about turnaround times, some more about R&D. If we understand our client’s problems, then we can provide better service. We see ourselves as problem solvers. We lean heavily on our technical team members like Aldwin, who not only have tremendous amounts of experience and education, but also great networks to utilize when a customer needs help, even when it falls outside of our local expertise.
The GCxGC/MS instrument, used for Veda’s advanced R&D testing
Last but certainly not least is the advanced R&D testing that we do. When we first started, we started talking to farmers and manufacturers trying to understand their challenges. What data were they not getting? How would a testing lab better serve them? So, we started investing strategically in certain instruments that would allow us to better serve them. We’ll get into this later as well, but we invested in a GCxGC/MS, which allows us to get more visibility into things beyond the typical panels, like more terpenes and other volatile compounds including thiols and esters. We did that because we knew there is value in that. The data our customers were getting prior just wasn’t enough to put together really great breeding programs or to manufacture really consistent products, you know, to move toward that next level of innovation in the industry.
Aldwin: Leo mentioned advanced R&D and it’s basically the same approach that I mentioned before. It’s not just telling you what you can and cannot do. It’s about asking them what do you want to do and what do you want from a lab? If we have a problem, let’s see if we can solve it. That’s how the GCxGC/MS came into play because we knew there was a need to test for many terpenes and other volatile compounds. The common complaint we received was why two terpene profiles differ so much from each other, even from the same genetics.
This is something that would actually give the customer, the cultivator or the manufacturer: data about their product that they can actually use. For consistency, for better marketing and other reasons. We are trying to help them answer the questions of ‘how can I make my product better?’
You know, for example, clients would tell us they want something that has a specific taste or smells a certain way. Nobody is telling them what makes the flavor or smell. There is a need there that we can fill. We are trying to provide data that they, the customers, need so that they can improve their breeding programs or their formulations. Data they can use, not just data they need in order to comply with regulations. They would ask us what we can do. We listen to our customers and we try and help as best we can. We don’t know every answer. We are discovering there is a lot more to terpenes than what you can find on a traditional one dimensional gas chromatogram. Some of the terpene data that our clients had previously is not really actionable data, which is where the GCxGC/MS is helping us.

Just as industry experts have developed a set of tools to assess artisan experiences with wine, craft beer and diamonds, our team of cannabis cultivators at Good Chemistry Nurseries- who hold decades of experience backed by extensive education in horticulture and botany- have developed a new consumer guide to evaluate the essential aspects of cannabis called STATS (Sight, Touch, Aroma, Taste, Sensation). We hope the newly developed guide will begin an industry-wide dialogue about consumer education and provide fundamental knowledge on how to evaluate the quality of a cannabis flower.
A view of the materials for consumers
STATS was created in response to our customers’ growing desire to differentiate between high quality and low quality flower. Two years ago, a consumer may have walked into a dispensary, and may have been thrilled just to be able to buy legal and safe cannabis. Fast forward two years, and now they’re asking, “How do I recognize quality cannabis?” By introducing STATS as a consumer awareness campaign, we are hoping to meet the needs of consumers to understand the complexities of the cannabis flower, as well as opening up the industry to a more conservative market that might be overwhelmed and intimidated by the cannabis culture.
STATS, which is available at no cost at statsguide.org and at Good Chemistry dispensary locations, is designed as an interactive booklet that breaks down the complexities and characteristics of quality cannabis through the five main categories; sight, touch, aroma, taste and sensation. The short, easy-to-read tool also comes with a concise glossary, which includes definitions of cannabis-related words, and expressions that might not be palpable to a novice consumer. Here is an overview of the STATS tool to evaluate quality cannabis:
The STATS take away guide book for consumers
Sight:Seeing the flower can sometimes be the only evaluation option before purchase. It is important to know the visual cues for remarkable cannabis. STATS help consumers evaluate qualities including: trichome content, color, structure, size and trim.
Touch:Touching the flower can help with evaluating the cure, or the controlled drying process used to achieve proper moisture content post-harvest. STATS define how the bud should feel.
Aroma:Distinctions can be made between high and poor quality cannabis aroma. Because each flower strain can have a unique scent, STATS reviews what scents should be expected, and what smells can denote poor quality.
Taste:Different flowers strains will have unique flavor profiles. Similar to wine tasting, experience is necessary, STATS helps consumers learn to distinguish between different flavors among the flower strains.
The development team of STATS
Sensation:The first sensation that comes from cannabis is the sensation of lift, or of being high. Varying experience levels may affect how people feel with each strain and the amount of time people feel lifted. We have identified the key categories of sensations that come from different strains including amplify, relax, relieve, and sleep.
Now, there is an easy and free tool to provide novice and aficionado cannabis users new insight and understanding into the purchase they’re about to make. Good Chemistry Nurseries developed STATS in conjunction with our Colorado-based master cultivators Duncan Cameron, Scott Toland, Heath Byington and Stephen Spinosa. Our development team came to this idea with a strong desire to address consumers’ interest in learning more about how to assess high quality cannabis.
