what is the chemical in mushrooms
Dried mushrooms contain about 0.2 to 0.4 percent psilocybin and only trace amounts of psilocin. The typical dose of psilocybin is 10 to 50 milligrams (roughly 20 to 30 grams of fresh mushroom, or 1 to 2.5 grams of dried mushroom powder) with peak effects occurring in 1 to 2 hours, and lasting for about six hours.
