Magic mushrooms, including those with psilocybin and things like A. muscaria, typically begin to kick in within about 30-60 minutes. Effects generally peak after an hour or two, and the entire trip will likely last from four to six hours. 

There are, of course, personal and biological factors that can affect how long your shroom experience lasts. The potency of the shrooms in question, the dose you take, and your own metabolism can all influence how strong a trip is and how long it sticks around.

Once your trip has come to a close, you can likely expect the remnants of your fungal friends to linger in your body for about one to three days. Keep in mind, though, that most standard drug tests don’t check for magic mushrooms, and if they do, they’re almost certainly looking for psilocybin. 

If drug testing is a concern of yours, it might be best to choose shrooms that are psilocybin-free or time your trips to leave enough days for your body to purge it from your system.

Shrooms that contain psilocybin are considered federally illegal, at least in the U.S., because psilocybin itself is a Schedule I Controlled Substance. This means that, in the eyes of the federal government, psilocybin has a high potential for misuse, no accepted medical uses, and can only be safely used under the supervision of a medical professional. 

Whether or not this classification of shrooms is really fair is up to you, but there are fortunately other options for those looking to experiment without breaking the law. Remember our friend Amanita muscaria, the classic red-and-white toadstool mushroom? Its active ingredients are not controlled substances, which means they are not subject to the same restrictions and legal penalties.
