Are expired shrooms dangerous?

Magic mushrooms, like any mushrooms, can develop mold or bacteria over time and if they’re not stored properly. Consuming some molds can cause an allergic reaction or respiratory problems in some people, so if your magic mushrooms have visible mold on them, do not consume them.

Shrooms will lose potency over time, but the old age of a mushroom won’t necessarily influence the effects you feel. If anything, they will just be less potent.
