Your trusty Daily Leaf correspondent rarely consumes cannabis beverages. Perhaps he should; As the march of cannabis capitalism continues, innovators have developed novel technologies to improve the consistency and absorption rates of beverages with THC and CBD. Through improvements in the emulsification technology that allows cannabinoids oils to remain suspended in the drinks and the creation of fast-acting THC isolate sugars, new cannabis beverages deliver THC or CBD at a pace that vastly improves upon most edibles.

On those occasions when we have tasted a THC tipple, we’ve always found them in glass bottles. This may have been a stroke of good luck. Recent discoveries, reported by Yahoo Finance, suggest that the lining in aluminum cans may absorb substantial amounts of the cannabinoids contained in a drink.

When Lagunitas shifted a “cannabis-infused hoppy sparkling water” beverage line from glass bottles to cans in order to cut costs, the team of scientists that developed the technology to suspend cannabinoids in water decided to test the product. They found a substantial loss in potency, theorizing that the cannabinoids adhere to the lining of the can after it has been opened and the drinker begins to sip.

The good news is that for most consumers, the loss in potency is likely to go unnoticed. At 18mg of CBD and less than 2mg of THC per bottle, only the most sensitive of souls are likely to get any buzz of this beverage at full potency. 

Given the highly fragmented nature of the cannabis drink market, these findings are likely to impact some states or countries more than others. According to the same Yahoo Finance report, most Canadian recreational cannabis beverages are sold in aluminum cans. We welcome our neighbors to the North with open arms should they fancy a more suitable vessel for their canna-coolers.
