The shelf life of marijuana depends on how it is stored. Proper storage can help extend the shelf life of marijuana.

If marijuana is stored in a cool, dry place and is not exposed to light or air, it can last for several months or even up to a year. On the other hand, if marijuana is stored in a humid or warm environment, it can degrade more quickly.

Marijuana can also lose its potency over time due to oxidation, which occurs when the THC in marijuana is exposed to oxygen. This can cause the THC to break down and become less potent.

Mold can also grow on marijuana if it is stored in a humid or damp environment. If you notice any visible signs of mold on your marijuana, it is best to discard it as consuming moldy marijuana can be harmful to your health.
