The race is on for drinkable cannabinoids. In mid-December, Tilray announced a $100 million joint venture with Anheuser Busch to research and develop infused non-alcoholic drinks for the Canadian market.

This is the second big beer company to partner with a cannabis industry leader (see Canopy Growth’s partnership with Constellation Brands), who has just invested another $4 billion in the company.

Molson Coors also announced a deal with Hexo in August. On the non-alcoholic side of the ledger, Coca-Cola and Aurora have also had talks, reportedly eyeing the cannabis market.

Short term in other words, a lot of drinkable cannabis is coming to a market near you.tilray-logo

Why Is Drinkable Cannabis So Intriguing?

Cannabinoids themselves, are not water soluble. However, when cannabinoids are subjected to a process called nano emulsion, (emulsified oil, water and molecules), they can be not only added to drinks but potentially represent one of the most cutting edge forms of drug, vitamin, mineral and overall nutrition delivery. Nanoemulsions are approximately the size of viruses, proteins and antibodies with a transparent or semi-translucent appearance. They also tend to increase bioavailability of substances.

In other words, while the focus on the market as it is developing in Canada is “recreational” and “beverage” use, in fact, this technology can be applied to food. It will also be used, obviously on the medical side of the equation too.

Nanotechnology overall is actually a manufacturing technology that works with atoms to change the structure of matter. When it comes to edibles of all kinds (food, drinks and medications) nutrients are absorbed more uniformly and pass through to membranes directly into human cells.

The impact of that technology, mixed with a revolutionary drug, is no longer theoretical.One of the best known uses of nanotechnology in the world is also one of the most common condiments. Mayonnaise for example, is an emulsion of tiny particles where oil and water are mixed together without separating. That said, these days researchers are developing techniques that allow these tiny droplets to be precisely tailored to give them specific tastes and textures.

The technology, in other words, that the cannabis and major drinks manufacturers are now developing, will allow cannabinoids to be used in food, drinks and medications in ways that go far beyond pills and oils.

This is not your grandparent’s beverage, food, drug or alcohol market in other words. This represents another way for the cannabis industry to lead the way on a range of products far from “canna-beer.” Or even THC-infused social lubricants.

The impact of that technology, mixed with a revolutionary drug, is no longer theoretical.

The Cellular Revolution of Cannabinoids Is Now Here

If allowed to efficiently access cells via nanotechnology, no matter how it is consumed, the idea of a cannabis infused food or drink might well become enough not only to “keep the doctor away” but in general revolutionize concepts of nutrition, not to mention medication.

That said, there are still many questions in general that remain about the safety of this kind of technology within the human body. Nanoceuticals can help bypass typical protective barriers of the body and deliver bio-chemicals that the body would not normally encounter. There has not been a lot of study (yet) on their biodegradability or metabolism of nanotechnologies. Namely the human body may not be able to expel them. They are currently unregulated and can be introduced to the market with little or no evidence of safety or efficacy although this is also on the way. There are concerns that this delivery method could literally disrupt DNA.

Cannabinoids themselves appear to be a systemic biological regulator. But the active ingredients used to emulsify the plant may or may not be.

In an industry in other words, which has systematically been ahead of regulatory approval, starting with legalization itself, the future looks not only highly intriguing, but full of major debates about with what and how human beings are nourished, and treated medically.

As usual, in other words, the cannabis industry, is pioneering a truly brave new world.

Safety & Efficacy: Ensuring Dosing Accuracy for Infused Products

Complications with dosing inaccuracies in the cannabis industry has always been a hot topic. In 2014, The Cannabist tested several Colorado infused products only to find that the results were different from what was indicated on the label. While the industry has come a long way at the state level since then, a study published in The Journal of the American Medical Association this past November found that 26 percent of CBD products sold online contained less CBD than the label. Similar to when you buy a bottle of wine or ibuprofen, people should be able to trust product labels.

There are processes that cannabis-infused product manufacturers can adopt to solve this issue. Incorporating process validation establishes reproducible customer experiences while in-process controls create product consistency and potency reliability. These operational and compliance techniques originated in the pharmaceutical industry and will undoubtedly become the future gold standard for best practices with cannabis manufacturers.

Product testing alone cannot assess quality for an entire lot or batch of product; therefore, each step of the manufacturing process must be controlled through Good Manufacturing Practices (GMP). Process validation is an aspect of GMPs used by the pharmaceutical industry to create consistency in a product’s quality, safety and efficacy. There are three main stages to process validation: process design, process qualification and continued process verification. Implementing these stages ensures that quality, including dosing accuracy, is maintained for each manufactured batch of product.

Validation: Step 1

Process design, the first phase of process validation, defines the manufacturing process based on previous product development and process research. The appropriate equipment, instruments and materials are selected as part of process design. Both standard operating procedures for equipment and operations as well as batch records for manufacturing steps are also finalized during this phase. The batch record must include critical process parameters (CPP), the parameters that must be maintained in order to produce product that consistently meets specified criteria. Mixing speed and time, temperature, pressure and flow rate are examples of common CPP. Training production personnel is also defined and performed as part of process design. Operators are trained on operating procedures and batch records in order to learn how to make the product successfully.

Validation: Step 2

Process qualification, the next stage of process validation, is performed to evaluate the capability of a process for reproducible and robust manufacturing. Because reproducibility of a process cannot be fully assessed with a single batch, evaluation is typically performed on a minimum of three separate batches. For each batch included in the process qualification, the frequency and number of samples are increased over normal sampling to provide a more thorough assessment of each batch. The testing includes visual inspection for defects as well as quantitative tests such as weight or volume and potency. In addition to composite sampling, which is performed by combining samples from multiple time points throughout a batch (e.g. beginning, middle and end) to assess a batch as a whole, stratified sampling is performed. Stratified samples are taken from specified points throughout a batch, and rather than being combined, the samples are tested separately to indicate consistency throughout a given batch.

The Stratos product lineup- validation helped produce each of these consistently.

In addition to evaluating the reproducibility of a process, tests for robustness are performed during process qualification to demonstrate how changes in a process may impact the product. It is important to use different operators for performing manufacturing steps to ensure changes in personnel do not affect product quality. Switching out equipment and instruments will also reveal any sensitivities in a process. For example, when a different oven, mixer or tablet press is used, are the appearance, texture and potency impacted? If the product remains the same, that points toward the process being robust. Challenging the CPP will also provide important feedback regarding a process. If a step requires a temperature range of 50° – 70°C, it is recommended that the process be tested at the low end and high end of the range, to ensure the final product meets all required specifications. If the range assigned to a unit’s gross weight is 500 g ± 5%, then testing at 475 g and 525 g will offer more insight into how much variance the process truly can withstand.

Validation: Step 3

Once the process has been assessed for reproducibility and robustness, it transitions to continued process verification, which is the third and final stage of Process Validation. Performance of quality checks during each batch for the life of a product is part of this final stage. For infused products such as tablets, these checks include appearance – the tablets are the color and shape indicated by the batch record and they include the required imprint(s); weight – the tablets are within the specified weight range, which indicates correct tablet size and consistency of ingredients; hardness – tablets will dissolve/disintegrate for proper dosing; and friability – tablets will withstand stress of routine handling.

As your company grows in manufacturing volume, each of these three steps will become critical to safeguard against any inconsistencies. As we know in this industry, our most valuable asset is our license and success can be negatively impacted based on meeting compliance. Dedicating an internal role within quality and compliance will serve to future-proof your business against additional rules and regulations that are likely to come.

Cannabis-Infused Beer Goes Mainstream

Lagunitas Brewing today unveiled a new beer infused with cannabis, making it the first large national brewery to experiment with cannabis. Lagunitas, now owned by Heineken, announced the launch of their “Supercritical Ale,” an IPA brewed with terpenes extracted from cannabis.

The brewery chose to partner with AbsoluteXtracts and CannaCraft, based in California, for their cannabis extract and will use hops from Yakima, Washington. “We’ve long known about the close connection between cannabis and hops,” reads their website. “Now Lagunitas is excited to partner with a like-minded neighbor in Sonoma County, AbsoluteXtracts, to close the gap further with tandem innovations on the topic.” Hops and cannabis belong in the same taxonomic family, Cannabinaceae, and they also have a number of physical similarities, which helps explain the “close connection” they are referring to. The website says the beer will only be available in California—for now. According to Fortune Magazine, the terpenes come from two strains, Blue Dream and Girl Scout Cookies (known as GSC in some states).

The name “Supercritical” comes from the state that carbon dioxide is best used as a solvent for extracting compounds from plants. Terpenes are responsible for the aromatic properties of plants, giving hops the piney and citrusy flavors that come in IPAs, and giving cannabis the same flavors and smells as well. Limonene, for example, is a cyclic terpene molecule that gives us a citrusy smell and flavor.

Coalition brewing Co.’s Two Flowers IPA

They’re not the first brewery to experiment with cannabis-infused beer; smaller craft breweries have been doing it for some time now. Coalition Brewing Co., based in Portland, Oregon, sells a cannabis-infused beer called Two Flowers IPA, with 3mg of cannabidiol (CBD) in a 12oz glass. Dad and Dudes Breweria, based in Aurora, Colorado, also put out a CBD-infused beer last year, called General Washington’s Secret Stash. According to Westword, Dad and Dudes was the first brewery to receive federal approval for a CBD-infused beer, but since the DEA declared cannabis oil illegal last winter, the Alcohol and Tobacco Tax and Trade Bureau rescinded their approval.

The common denominator between these three beers is that none of them contain THC, the popular psychoactive ingredient in cannabis. Perhaps Lagunitas is taking a safer approach with regard to federal legality by only using terpenes, not CBD, and only offering it in state. Coalition’s Two Flowers IPA is also only available in Oregon, but does, however, contain CBD. Check out the video on Lagunitas’ Supercritical Ale below.
