The science of freshness

“You wouldn’t leave a glass of wine out all night and expect it to be fresh or taste the same the next day,” says Serge Chistov from Honest Marijuana Company in Colorado.

Chistov sounds like a scientist as he discusses perishability and the chemical changes over time that degrade cannabis.

“Marijuana, like most plant and animal matter, is perishable,” says the company’s website. “That means that it is likely to decay, go bad quickly, or lose inherent properties that are important to the product. To put that in perspective, think about a 2-liter bottle of soda. When you first open the bottle, if the product is good, the carbonation is still a big part of the experience. The soda is fizzy, and that’s fun.

“But now think about that soda two days later. No matter how tightly you turned the cap, the carbonation has escaped and the drink is no longer fizzy. The soda has gone flat. Though it’s still safe to drink, an inherent property that is important to the product—and the experience—has disappeared. That’s perishability.”

Light, oxygen, humidity, and temperature all combine to degrade a flower, joint, or concentrate after repeated openings. Why is this degradation bad? Because it minimizes “the entourage effect,” says Honest Marijuana’s Web site. That is, it’s a combination of THC, CBD, terpines, etc., that contribute to the effect marijuana has, and if one component of that entourage is degraded, the overall effect is negatively affected.
