Let’s say you chance upon a stash of weed you forgot about some time back. Happy day! But … is it even good? You don’t even remember stowing it away, let alone when you bought it. Can you still smoke it?
Can Weed Go Bad?
The good news is, weed doesn’t really “go bad;” its chemical makeup just changes. Marijuana is a plant, just like the veggies and herbs in your kitchen. Cells break down, molecules oxidize. Just as the dried oregano in your spice rack becomes less flavorful over time, weed becomes less potent. Old weed won’t kill you, but it also won’t get you all that high.
How to Store Weed
The best way to avoid this question in the first place is to store your weed properly. Glass or ceramic containers are your best bet. You want to make sure the container is airtight, and won’t transfer smells or flavors onto your precious weed. Store your pot in a dark, cool refuge that’s not your refrigerator or freezer — too cold environments can suck the sweet, sweet moisture out of those leaves. Fresh weed is full of the cannabinoids CBD, CBC, and THC, but sit your weed down for a bit in ultraviolet light (i.e., sunlight), and your THC will break down into CBN, a cannabinoid that is way less potent and much more disappointing. Basically: Keep your weed in a still, dark, cool environment, and you’re guaranteed the best flavor.
But let’s say you didn’t get around to storing your weed like you should have, and now you’re stuck with a Ziploc bag of mystery marijuana that may or may not be good.
If your recently discovered stash doesn’t look much like weed anymore, just some dried out powdery leaves, it’s probably not going to be all that enjoyable to smoke. If you spot a fuzzy white powder growing on it, your weed is moldy and you definitely shouldn’t smoke it, unless you want to risk heart and lung problems. Mold spores, like moist places without a lot of airflow, which can happen if you store your weed where it’s too moist.
