If you’re like me, every once in a while, you set aside some bud for later or just forget that you have it all together. When it’s found again, you have the thought “…I wonder if this has gone bad” because we’ve all we’ve all been burned by a carton of milk… at least once.

Great news stoners: weed doesn’t go bad, sort of.

Old weed doesn’t rot or poison you or make you physically ill. Mostly, it’ll just be terrible to smoke and burn your throat when you inhale it. Also, if you leave it in a damp place, old marijuana can grow mold on it. Old weed will also go bad in the sense if decreasing in potency depending on how it was stored. The THC, or technically the THCA, can be converted to CBN, which is less psychoactive than THC.

Overall, if you store your weed correctly, it can last for years. If you don’t, it just won’t make you as high as it did when it was fresher. The best way to store you weed to not let it go bad is to keep it in a glass or ceramic jar in a cool, dry place. Vacuum-sealing it works great too.

But what if you already have bud that’s too dry? Fear not, my stoner friends. Though it may not restore the THC that was lost, there are ways to rehydrate bud that’s already too dry to smoke comfortable. You can also vape it, or make edibles with it. All is not lost, friends.

Let me know about your experience with old weed!
