Yes. Even though these fungi are devoid of water, they can go bad, so you must learn how to store magic mushrooms properly. Proper storage can preserve potency for months or even years.
Steps on how to store dried mushrooms:
Store in clean, dry, airtight containers, such as a mason jar, vacuum-sealed container, or resealable bag.
Place the container in a cool, dry area away from heat sources and high humidity. You can also wrap it carefully in aluminum foil to protect it from light.
Use decent desiccant packets or silica gel to absorb moisture and prevent mould.
Mark the strain and date of drying to track freshness.
Keep children and pets out of reach to prevent accidental ingestion.
