Well, it certainly does deteriorate over time. That's why, for instance, when they compare old 1970s pot to today's pot they come to the conclusion that pot has gotten a hundred times stronger in the past few decades (and somehow that's a bad thing). Probably if it's been a year and it hasn't been stored properly it will have lost enough THC to be non-psychoactive.
ermitonto Reviewed by ermitonto on . How old is too old? How old is too old? If you find an old bud some place you didnā??t expect to find it like an old hiding place can you smoke it? Does it loose its THC? What is the oldest grass you ever smoked? Does it have an expiration date?..........help please. Rating: 5
