Do Magic Mushrooms Expire?

Magic mushrooms, also known as psychedelic mushrooms, are prone to mold growth and rot. They can last anywhere from a few days to up to a year depending on the harvesting and storage methods and conditions. The longest-lasting conditions are if the mushrooms are stored properly.

Psychedelic mushrooms can go bad, but the method of storage determines the length of their shelf-life and the viability of their psychoactive compounds. Fresh mushrooms will last for several months to years without losing their potency or going bad. Dried psilocybin mushrooms should be stored in paper or perforated plastic.

If magic mushrooms aren’t stored properly, they become highly susceptible to mold or bacteria. Even if they don’t rot, the active ingredients in the mushrooms will break down over time, causing your shrooms to rot quickly. If you store them in the fridge in a paper bag, you may be able to store fresh shrooms for up to two weeks.

Psychedelic mushrooms, like LSD, peyote, and marijuana, are listed on the Controlled Substance Act’s Schedule 1, along with other substances like psilocybin and psilocin. However, generally speaking, mushrooms can go bad, except for dehydrated mushrooms, which require water/moisture to grow.

The production, sale, and possession of magic mushrooms are illegal in Canada. There is increasing interest in the potential therapeutic uses of magic mushrooms, and Johns Hopkins researchers surveyed nearly 2,000 people about “bad trip” experiences and urge caution around the use of hallucinogen psilocybin. To preserve the integrity of your shrooms, it is essential to store them properly and avoid consuming them for a long time.
