Magic mushrooms need to be consumed to produce the effects of the hallucinogen psilocybin. This means that they must interact with your digestive system in order to work. The mushroom version you choose is just as creative as how you consume them. Another aspect is the dose amount and the different effects that result. The whole purpose for some is hallucinogenic effects; others are looking for other effects. Some people like taking certain amounts that do not result in hallucinogenic effects. Magic mushrooms can elevate mood and induce perception if properly dosed. Research indicates that several brain regions increase activity across a wider range of functions.
