Why anyone would ever choose to risk an edible going bad is beyond me. But, in cases where you’ve got to cleanse for a drug test or simply hide them from relatives, it’s important to know how long edibles can last before losing their potency. Some people assume that the longer an edible sits untouched, the more potent it becomes.
Keep it fresh
In general, the potency of most edibles remains steady for a while, then decreases very slowly over time. In fact, Stan Zislis, owner of Silver Stem Fine Cannabis in Denver says,
The THC level pretty much remains the same.
This seems like good news, but when it comes to perishable items, other concerns come into play when it comes down to eating that three-month-old edible sitting in the back of your refrigerator.
Overall, you’ll want to keep your edibles from going bad. Sure, it’s got marijuana in it, but that brownie, cookie, cheesecake or whatever else can indeed spoil if not stored properly.
Medical marijuana dispensaries will often print expiration dates on edible items, but if not, it’s not a bad idea to ask approximately how long it will be safe to eat.
The longer you can preserve the food or confection itself (with air-tight sealing for instance), the longer your product will retain its potency and overall freshness. This means that if you’ve kept an edible in a hot car, or unsealed on a counter for several weeks, potent or not, eating it may not be the best idea.
Danica Lee, a spokesperson for the Denver Department of Environmental Health said,
When [an edible] past its prime, it’s going to develop spoilage organisms, things that might cause mold, an off taste.
If you have a ‘mature’ edible lying around, be sure to check for moldy spots and give it a good sniff. If it looks or smells off in any way, toss it.
Keep in mind that if you do decide to consume an aged edible, it may produce different effects. Some report even greater ‘couchlock’ or lethargy that tends to hang on longer than expected.
What about frozen edibles?
If you must put your edibles aside for a rainy day, freezing them to preserve from spoilage or any losses in potency may seem like a good idea.
However, the increased moisture content once an edible is thawed can ruin the quality of your high (not to mention the taste). Some do report that they are able to freeze cannabutter, gummies, and other items without diminishing their flavor or potency.
The best course of action is to simply consume your edibles immediately, if not sooner. Or, give them away before they have a chance to go bad.
