If stored properly, magic mushrooms can live up to a year.

Magic mushrooms, like other drugs, lose effectiveness while stored. Shrooms can become deadly if they go bad, unlike other compounds.

This post explains how to determine if your shrooms are rotten, what you can do to salvage them, and how to store them properly to avoid this issue.

How do mushrooms spoil?

Magic mushrooms decay and mold like other plants. If shrooms produce bacteria or mold, they’re unsafe to eat. Bad shrooms are called baddies. This makes them unsafe to eat.

Even if mushrooms don’t produce mold or bacteria, psilocybin degrades over time. Degraded mushrooms may still be safe to eat, but they’re less strong.

Mold and germs can grow on mushrooms if they’re stored wet or fresh. Heat, UV light, or oxygen degrade shrooms’ active components.

Mushrooms how long?

Safe shroom lifespan varies on storage method and type:

3–5 days for fresh mushrooms.
6–12 months for dried mushrooms.
12–18 months for microdose capsules.
(12–18 months)
2–3 years for mushroom honey.

Fresh mushrooms rot and mold quickly, so they’re only safe to eat for a few days. Fresh mushrooms can be stored in a paper bag in the fridge for about ten days. Fresh mushrooms kept in a plastic bag or airtight container may mold and rot.

Dried mushrooms keep longer, both potently and safely. If you keep dried shrooms away from sunshine, heat, and oxygen, they’ll retain potency for two years. Minimizing container moisture helps keep mold and germs at bay.
