More Than a Hashtag: It Feels Good to Do Good

Here at Avitas, we love what we do. We work hard to create excellent, pesticide-free cannabis products, and we’re passionate about getting them right. But that’s not all we think about. Flower and oil may be our focus, but we believe it’s our responsibility to make sure our vision is broader than just our products, and we actively seek out ways to go above and beyond the demands of our business. Joe Bergen, General Manager of Avitas Oregon, puts it plainly, “I think we have a responsibility to be good stewards of our resources and the profits that we derive from those resources. We want to make sure that we’re taking steps to make our products better, but also keeping an eye on the larger picture.”

As a company, we love to give back. It’s built into our DNA. Our co-founder, Adam, says “Part of what I wanted when I built Avitas was a company that I could be proud of. How we run the company matters, not just the products we’re putting out into the world but also, how we treat our employees, and how we use our success to give back to the community.”

It feels good to do good isn’t just a slogan for us. We’re always on the hunt for ways to put even just a little bit of tangible goodness into the world. That’s why, this year, we’re continuing to give back. We’ve partnered with several local food banks who work tirelessly to ensure that all Washington residents have access to food while respecting their dignity and promoting good health. One in six Washingtonians relies on their local food bank for the meals and one in seven Washingtonians relies on SNAP (food stamps), the Supplemental Nutrition Assistance Program, which is severely threatened by budget cuts. What’s more, half of all people on SNAP are kids. We don’t think anyone should ever go hungry, but especially not during the holidays, which is why we’re proud to partner with these organizations because we know they are committed to nutrition and healthy eating while reducing hunger.

We’re always looking for ways to help give back to our community. If you know of a need in the community or a local charity or nonprofit organization that we might be able to help, send us an email. We love being able to support the community that’s helped us grow.

After all, it feels good to do good.  


Serendipity & the Science Director: Amber Wise's Avitas Journey

At Avitas, we think it’s incredibly important that people understand the chemistry behind the cannabis. That’s why we’re transparent about our methods and are committed to integrity in everything we do from testing for pesticides to our full-spectrum extraction process in our oils. That’s why we try to go above and beyond in our scientific approach to cannabis, which brings us to our talented Science Director, Dr. Amber Wise.

An Unlikely Journey

A few years ago, if you’d told Amber she’d be the Science Director for one of the leading cannabis producer/processors in the Pacific Northwest, she wouldn’t have believed you, but now she laughs, “Nineteen-year-old Amber is really excited about what’s happening right now!” A little over a year ago, Amber, burnt out on academia and looking for a change, met our co-founder, Adam, at the Cannabis Science Conference in Portland. Adam was immediately impressed by Amber saying, “We’d been on the hunt for a Science Director for a while, and I was thrilled to run into Amber at the conference. I thought she’d be a great fit for Avitas.”

Amber brings a vast field of knowledge to our team. She has her B.S. in Chemistry from the University of Wisconsin, Stevens Point, and her Ph.D. in Chemistry from the University of California, Berkeley. She finished off her studies with postdoctoral work at the University of California, San Francisco studying chemical exposure risk and toxicology and a stint as a science policy research intern chemical exposure, risk and toxicology with the Union of Concerned Scientists. Her command of chemistry is far-reaching and much-needed in our growing industry.

Cannabis + Chemistry = The Perfect Match

There are quite a few Ph.D.s in analytical labs, but it’s relatively unique to have a Ph.D. in this position at a producer/processor. Amber believes that as the industry continues to grow, having Ph.D.s in this area will become an industry standard. She explains, “There’s a real need for scientists--and good ones--in this industry. There’s so much basic research that needs to be done on everything from extractions, to profiles of strains, and genetics.”

She continues, “Most typical commodities have had tons and tons of scientific research done on its different properties, but cannabis is lagging way behind for a variety of different reasons.” She reveals that this has to do with the fact that cannabis research is still illegal at the Federal level and that though there are interesting studies ongoing abroad, most of the research that’s being done is within private industry, so very few people are particularly interested in sharing information because it’s proprietary. The secretive nature of cannabis research needs to change. Some of Amber’s focus is on networking. Reaching out both on a peer level, through educational seminars for budtenders, and giving talks at cannatech meetups. And, to be honest, it’s a lot of hard work.

Work Hard, Play Hard, Work Harder

That’s something nineteen-year-old Amber might not have counted on, but Dr. Amber Wise takes the challenge on with a smile. “There’s a lot of misconceptions from outsiders about the cannabis industry. We start early, have a very strict work schedule, punch in punch out. It’s not like we don’t have a good time. It’s just very professional.”

The cannabis industry still has a long way to go in terms of fully understanding the wonders of the cannabis plant. A great deal of research is still needed to help guide processes and procedures across the board, but we’re sure glad to have Amber onboard to help lead the way in chemistry as we continue on our journey.

If you ever have a science-related question about our process or products, Amber is happy to answer them--just send her an email!


Avitas Origins: From Kitchen Table to Cannabis Calling

Here at Avitas, we’re both dreamers and doers. We love our jobs and our customers, and we love that we get to grow the best flower and bring you the most amazing oil on the market. But, you already know all of this. What you may not know is that we might not be here at all if not for some family time, a stunning vision, and a little needed encouragement in a warm and cozy kitchen just five short years ago.

It all started around a kitchen table. Back in 2012 as Washington State weighed the pros and cons of marijuana legalization, Avitas co-founder, Adam, sat in his parent’s kitchen talking pot with his family. He was all for legalization, Adam himself has enjoyed cannabis for many years, but he worried about this new and fragile market. Legal cannabis is a brave new world in America, and Adam soon found himself painting a passionate vision of what he’d like to see happen in this expanding frontier. Adam laughs when he recalls it now, “I didn’t realize it then, but that’s where Avitas was born.”

Adam has a had a long and successful career outside of cannabis. He came up through the ranks as a software engineer at Microsoft before moving into product management at Microsoft and then at Disney and ESPN. He’d seen what truly customer-centric companies could accomplish and slowly but surely, Adam realized that he wanted to create a brand like that in the cannabis world. He wished to build a company that consumers could trust to have their back, and he wanted to help shape how marijuana is grown, distilled, and packaged to help lift the stigma and misinformation that still exists around this amazing plant. He envisioned a company that was committed to a natural, preservative-free product that operated with integrity and was transparent about its process in ensuring the quality of its own flower as well as the quality of the buds it bought from other farms. Adam knew that it was going to be a long, hard-fought journey, but even he couldn’t have known what his future held in store.

At first, the industry was a bit like the Wild West. Regulations were always changing, license requirements were under constant review, and the market itself was incredibly unstable, but Adam persevered. “We stuck to our core tenets: Customers, Quality, Community, and Environment and that’s pulled us through. As a company, we have to be forward thinking and have a true commitment to integrity; otherwise, we’d be nowhere.” No matter how tough things got, Adam kept this commitment to excellence in sight. And slowly but surely, this has shepherded the Avitas family from just the hint of an idea at the kitchen table to one of the leading producer/processors in Washington. We’re so glad to be on this journey. We hope that you’re up for joining us on our adventure into a world of cannabis that not only feels good but does good.


Grow your knowledge about our grow!

In addition to making high-quality CO2 extract cartridges, we started our company as a flower / bud producer.  We wanted to share a few of things we’ve developed over our years of experience that go into making our amazing flower.  We have our original facility in Washington and have our full, larger Oregon greenhouse up and running at full capacity now.

The tl;dr version is the following points – if you want to know more about any of them, keep reading!

  • We focus on great soil: that’s where it all begins!
  • Use organic, living and biodynamic pest control
  • Reproducible, consistent indoor conditions optimized for our strains
  • Invested a lot of time and energy perfecting our drying, trimming and curing process–not as simple as it sounds.
  • We’re our own harshest critic and only the best strains and finished bud make it to the shelves
  • Have years of experience

Great plants start with great soil:

We carefully mix every batch of soil with several amendments to enhance our plant’s natural immune systems and terpene profiles. Happy soil makes happy plants and consequently happy people!

  • Earth worm castings: these contain a highly active biological mixture of bacteria, enzymes, remnants of plant matter and animal manure, as well as earthworm cocoons. The castings are rich in water-soluble plant nutrients, and contain more than 50% more humus (organic matter) than what is normally found in topsoil.
  • Locally sourced organic compost: this energizes the soil food web, which is made up of microscopic bacteria and fungi, along with earthworms and many other life forms. Many fungi form mutually beneficial partnerships with plant roots, making it possible for plants to take up nutrients more efficiently. Research shows that compost enhances the ability of plants to defend against common diseases and may improve their flavor and nutrition, too. Compost provides nutrients and structure for many other living things in the soil, too.  We consider this “black gold” in our greenhouse!
  • Alfalfa meal:  an all natural fertilizer made from alfalfa plants. It feeds both the microorganisms that live in the soil and the plants that grow in it. It can also be used as an accelerant in compost piles due to its high biological activity.  It’s also a natural source of triacontanol, a plant growth stimulant.
  • Crab meal: an organic amendment loaded with critical nitrogen, phosphorous, calcium and magnesium nutrients for the plants.  It is slow release which is healthier for plants and  can also prevent pest eggs from maturing in the soil through an interesting mechanism:  The crab meal is made of chitin (the material shells are made from), so having it in the soil causes the natural microorganisms to release enzymes that break it down.  The pest’s eggs also have chitin in them, so the enzymes also weaken the eggs, causing them to not form/hatch properly.
  • Neem Cake:  a byproduct of the neem tree and leaf extraction process. It is an organic fertilizer, but neem cake also contains salannin, nimbin, azadirachtin and azadiradione as the major components which have natural pest repellent, insecticide, and insect growth disruptor properties.
  • Biochar: is made from plant and organic material waste and has been used as a soil amendment for thousands of years.  It’s proven to improve soil health, and plant health but the mechanisms aren’t exactly clear -it’s not a nutrient itself.  More recently as we understand the soil food web more, it’s been suggested that the high-surface area of biochar may provide “homes” in their microscopic nooks and crannies for soil microbes to live and thrive.
  • Mycorrhizal root powder: Our mixture contains thirty species of beneficial soil organisms that colonize plant roots and expand into the soil to greatly increase the absorptive surface area of root systems. Mycorrhizal fungi, Trichoderma and a diverse mix of bacterial species work symbiotically to promote improved soil structure and enhanced root growth.

Natural Pesticides

Most consumers know in general that chemical pesticides are “bad for you”, but many of these compounds convert into even more dangerous chemicals when smoked/combusted/vaped.  One of our founding principles is to be committed to all-natural, organic growing practices to ensure the safety of consumers and patients. Avitas only uses natural oils, beneficial fungus, and living beneficial, predatory pests to fight the damage from harmful pests.

Employing a natural integrated pest management strategy with cannabis plants is not easy, partly because there are very few, if none established protocols or research data to help growers in this newly-emerging market. We have been utilizing beneficial mites and insects for some time and recently attended a Washington State University / USDA  workshop on this topic to further our knowledge.

Here’s an introduction  to our three main helpers:

Stratiolaelaps (formerly Hypoaspis)a beneficial mite (not an insect–they have 8 legs) that lives in the soil and feeds on other harmful mites, root mealybugs, spider mites and springtails.  A good example of how you don’t have to be beautiful to be useful! (image: evergreengrowers.com)

Rove beetle (Dalotia coriaria) : Larger and easier to see in our greenhouse (it’s the black insect on the left), we use this to keep lots of small insects and mites away.  They live in the soil and are aggressive predators. (image: evergreengrowers.com)

Amblyseius swirskii : the larger, round creature that can be seen eating a thrips larvae below.  The swirskii are a great predatory mite that eats lots of soft-bodied pests: thrips, other pest mites, and the larvae of these species.  A perfect friend to have around to “maintain” the bad guys! (Image: Steven Arthurs, Univ. of Florida)

We will be expanding our use of beneficial insects very soon with two more and adding in these cute guys soon:

Cucumeris image: http://www.biconet.com/biocontrol/
image: North Carolina State Extension

Are you noticing how many of them look very similar?  We have regular checks of our plants and soil with a microscope to monitor the health of our system.  We also need to be knowledgeable enough to tell the difference between a “good” mite and a “bad” mite.

Someone asked me once if these “good bugs” ever end up in the buds–Not to worry!  They all live in or on the surface of the soil and don’t really venture out into the light much!

Indoor Farming

Growing indoors ensures a year-round, steady supply of “grade A” connoisseur level cannabis. Years of experience has allowed us to perfect our growing conditions (temperature, humidity, light/dark cycles, CO2 levels, nutrient levels, pH levels all contribute to overall plant health) and optimize our strains which reduces variability from crop to crop.  The terpene profiles and consistent bud formation cannot be matched, and our customers know exactly what they are getting every time.

Drying and Curing

Our plants are dried to perfection beginning with the harvesting of the plants. We start by stripping the fan leaves immediately from the plants to help with the airflow around the buds as they dry. Once dried and trimmed from the stems, the buds undergo a final hand manicuring prior to being placed into a climate-controlled room in our glass curing jars with special humidity adjustment for a minimum of two weeks. Like a wine aging, the final curing cycle brings out the nuanced aromas and flavors of our product.

Critical Connoisseurs

At Avitas, we only want to grow strains that we would like to smoke ourselves – in fact, our final decision to include a new strain or not is if we all agree on its flavor, aroma, and experience.  We have over 30 years of cannabis experience so we know how to tell when the genetics start to drift, and we keep up on what’s new to always offer high-quality strains for our customers.  We are always experimenting with our strain genetics and growing conditions and occasionally offer new varieties when we think we can improve on our already great harvests.

What’s the deal with flavored vape cartridges?

You may have seen or even sampled some flavored oils – things like pineapple or bubble gum or fruit punch.  There’s a chance some of those flavorings might be terpenes, but most likely many of them are not.

Many of the fruit flavors like banana, strawberry, mint, peach, raspberry are due to the presence of chemical compounds called aldehydes or ketones.  While natural fruits/plants do make these flavors, many of the individual molecules are very easy to synthesize in a chemistry lab – in fact, if you took any organic chemistry lab, you probably did a lab experiment where you made one of these fruity smelling compounds.

So what’s the difference between what you synthesize in the lab and what you find in a real raspberry?  The aldehyde molecule is the same, giving a “raspberry-specific” flavor, but in a real berry, there are also lots of other various molecules that add taste, aroma and experience.  The aldehyde molecule that is used for synthetic raspberry flavor is only present at very low concentrations in a real berry, which is why we don’t extract or concentrate these flavors from real berries – it’s just too expensive.  This is similar to the various terpenes and other compunds in a natural cannabis flower bud that lead to the “entourage effect” of each strain’s specific flavor, aroma and “high”.

There are two reasons this relates to cannabis vape pens: taste and viscosity.

Most of the yummy terpenes “disappear” during normal COoil processing and concentrating: those molecules are smaller and more likely to evaporate than the cannabinoids.  A few do remain in the end, but often user’s complaint about CO2oils is that the high doesn’t feel the same as smoking the flower– this makes sense because what’s left in the oil is mostly THC (that’s the potency people look for) and only a very small amount of the original terpenes.

Secondly, another interesting chemistry aspect about these types of concentrates (and particularly distillates, which we’ll discuss in another post) is that when you get to very high THC concentrations–above 90% or so–the oil get very thick.  To the point of almost being a brittle solid and stops functioning in a normal oil cartridge.  These can still be dabbed, but the convenience of a vape cartridge is lost along with all the flavors.

Processors overcome these 2 chemistry facts in a couple of ways.  To address the loss of flavor, other substances can be added: things like synthetic terpenes (fairly common), natural terpenes (fairly common) or cannabis-derived terpenes (much more rare), artificial aldehydes/fruity flavors, or other artificial flavors.  Additionally, the thick/solid nature of highly-concentrated extracts can be “thinned” with a solvent.  This can be as simple as leaving a small amount of extra ethanol in after the cleanup step, or by adding a cutting agent of some kind.  Common cutting agents include PG, PEG, VG, MCT, among others. (Propylene glycol, Polyethylene glycol, vegetable glycerin, and medium-chain triglycerides).  The MCT might appear on the label as “derived from coconut oil”–which is scientifically true.

This usually leads to the question: “why should I care if it’s natural or artificial if it’s all the same molecule?”

We can probably agree that eating lots of raspberries with some aldehydes isn’t that bad for you….However, there is very little known about the safety of smokingthese compounds, and in fact, recent scientific studies [1,2] suggest many of the artificial fruit and cream flavors and cutting agents convert to toxic compounds when heated to vape temperatures.

So how to know what you’re getting?  Reading the label very carefully and knowing your terminology can help, as well as asking very specific questions of the budtender:

What type of extraction process was used for this?  If it’s a distillate and in a liquid form, something was needed to thin it down. (COconcentrate is more correctly referred to as an extract).

Is it 100% cannabis-only or might there be other flavors or additives?  How do they know for sure?

Sometimes it can be hard or impossible to tell – I hate to say I’ve heard some less-than-honest stories about formulations and use of language on packaging.  Avitas never uses any cutting agents in our extracts and only 100% cannabis-derived terpenes that we carefully preserve for each batch.

Six behind-the-scenes things Avitas customers should know about

There are lots of topics I want to write about on this blog, but it will take a little time to cover all of them individually.  In the meantime, I put together an overview of some of the things we do behind the scenes that other extractors either aren’t doing at all, or are not devoting nearly the amount of energy or resources that we are.  The sentences with an *asterisk* I definitely plan to write more in-depth entries.  As always, if there are questions you have, leave them in the comments!

  1. We’re fanatics about testing everything for pesticides as it comes into our facility
    1. many people claim to have 100% organic products, but analytical labs report finding banned pesticides in many products on the shelf (between 40-80% in WA and 20-30% in OR have some sort of detected banned pesticide!*)
    2. this comes at considerable cost to us, as each test is over $300. When I discuss results with the scientists at the analytical labs, they tell me they don’t have other extract labs testing their trim material.
  2. The only chemicals in our extract and process labs (aside from organic cannabis) are:
    • pure COcarbon dioxide (comes in pressurized tanks)
    • Food-grade ethanol (fancy talk for highly pure EverclearTM)
    • Purified reverse-osmosis water
    • Solid CO2 (carbon dioxide) + rubbing alcohol (for our cold traps, does not contact product)

–we don’t use cutting agents like PG, VG, artificial flavors* or other fillers.

3. We carefully keep each harvested strain as a separate batch*

  • Sometimes we get a large batch, sometimes we get a small batch – that’s part of being reliant on a perishable/seasonal feedstock! To ensure the finished oil smells, tastes and experiences as close to the actual flower as possible, we don’t mix strains in our extractors.  That means our finished batch sizes are variable and it’s not always possible to find the exact same product month after month in your favorite retailer.

4. We enhance our finished oil with the full spectrum of terpenes collected in-house from each batch

  • previous blog post was written about terpenes, but the summary is: most companies who claim to have “terpene-enhanced” product are not getting them from cannabis and most folks have no idea where the source of these additives might be coming from*…..

5.  We spend more than most companies in research and development (R&D) of our procedure, tracking the cannabinoids and terpenes, fine-tuning our processing steps to optimize and improve the overall product.

  • We have a full-time PhD chemist leading our scientific team
  • We don’t currently have the expensive in-house analytical equipment, so it’s necessary to partner with outside analytical labs, which comes at no small cost to us, but it’s important to us that we feel confident we’re offering a clean and safe product*.

6.  Multi-point quality control checkpoints integrated along the process line*

  • I already discussed the additional pesticide screening before extraction above. We also check each batch for:
    • viscosity (how “thick” the oil is – for example, honey is very viscous, while water is much less)
    • color/clarity on visual standard scale
  • cartridge performance and reliability*: we have personal relationships with the overseas manufacturers of the cartridges and have been testing out many different iterations to ensure they have a smooth product delivery each time.

As you can see, we utilize top-level science and clean, organic processes to create a premium product for our customers and patients.


What does “Full-spectrum” mean and other fun terpene facts

Terpenes: they’re all around us! Literally – they make the great smells and flavors of things like lemons, lavender, fennel, pine trees, hops and lilacs.

They are, in fact, the reason for the “blue smoke” of the Smoky Mountains / Blue Ridge mountains in the eastern US. The pine trees in these regions emit enough terpenes into the atmosphere to scatter the light and create a bluish haze over the hills and mountains.

Terpenes and terpenoids are molecules built from a unit (think a “building block” molecule) called isoprene.

On the left: two isoprene units (5 carbons each). Middle & Right: two common terpene molecules showing how the two isoprene units make their structure

SO MANY things in biology use this small molecule to build things! Not only are they important as molecular building blocks, plants also use them for protection and as signaling molecules. Humans have used terpenes to our advantage as anti-fungal and anti-bacterial compounds (think tea tree oil), as precursors for medicine (taxol, synthetic steroids) and many other ways. Terpenes happen to have the right molecular properties for our smell and taste senses to detect.

There are over 120 different terpenes identified in cannabis. These are ACTUALLY what makes the difference between the various strain “highs” and different physical/mental effects–not if it’s an indica or sativa. Most strains have at least 10-25 different detectable levels of terpenes in their bud/flower, and the profile, or fingerprint, varies widely between strains.

When extracting/distilling/otherwise further processing flower material into a concentrate or extract, most–if not all–of the terpenes are lost, depending on the purification process. Highly pure THC doesn’t have the same feel, due to the absence of all the other compounds and the “entourage effect” of these molecules interacting with the cannabinoids and our personal biochemistry.

Most extract companies are savvy to this and have begun to add in terpenes. This is where the confusion and misleading language really comes in.

Since many different types of plants besides cannabis have terpenes, chemists can easily extract and isolate them (think limonene from lemons, or pinene from pine trees,) and sell them individually. Not to mention, these plants are legal everywhere, so you don’t need to have special cannabis licenses or even be in a legal state. In fact, it’s very easy to find these online and are completely legal to sell and buy. However, as already mentioned, each cannabis strain has multiple different terpenes that give its special smell/flavor/high. In each strain, a few terpenes are dominant/higher percentage, while most of the rest are at very low levels. It’s relatively inexpensive for a company to buy 3-4 of the main terpenes that occur in cannabis but are extracted from some other plant, and say it has a specific strain profile. It’s then easy to use terms like “100% natural”, “plant-derived”, “organic”, on the packaging.

However, you’re not getting any of the other lesser-concentrated terpenes at all. A nice visualization of this can be seen in the figure:

figure courtesy of http://www.evolab.com

I’ve created a process at Avitas that collects ALL the terpenes from each batch of our flower in the beginning of our process, so we have the full spectrum of terpenes represented. Then, we clean up the oil concentrate and remove all the other stuff that doesn’t taste very good like chlorophyll and plant waxes. Then, we carefully hand-blend in the terpenes from each batch at the end so the finished oil smells and tastes and feels exactly like the actual flower it came from.

I’ve really enjoyed developing this process since joining Avitas and look forward to using our clean and green chemistry to offer 100% cannabis-only strain-specific flavor profiles moving forward!


An introduction to our Scientific Director, Dr. Amber Wise

I joined the company in November 2016. I have a PhD in chemistry and spent most of my career up to this point as a chemistry professor, with some time spent working in the science policy and environmental health fields. I enjoy sharing with others the wonders of chemistry, and that’s one of my goals with this blog. I hope to help dispel some myths, clarify some language and in the process hopefully create a better-informed patient and consumer.

So far, I’ve been enjoying working in this exciting new field—it’s a fascinating intersection of science and policy, while occupying an interesting space of legality and highly-structured and regulated business rules. When I joined Avitas, the extraction team was already making a high-quality CO2 extract oil for vape cartridges and medical applicators. It’s been exciting to help make that already-great product even better with batch specific, full spectrum terpene blends, upgrading our process flow, and working with growers and analytical labs to guarantee all of our flower is 100% free of pesticides before we extract it.

When I’m not thinking about chemistry or cannabis, I enjoy sewing, gardening, and travel. I look forward to sharing some of my science knowledge and industry insights on this page along with some of my other colleagues here at Avitas. Unfortunately, there’s a lot of confusing and incorrect information out there regarding cannabis, so I hope to contribute to the growing body of useful scientific knowledge. Keep checking back for more posts!
