Magic mushrooms are organic hallucinogens that have been used for thousands of years.
What all these have in common is that they contain the mind-altering chemicals psilocybin and psilocin as well as traces of related chemicals. They are usually found as a small packet of dried vegetable matter, mainly grey in colour, with bluish and brownish bits, looking a bit like tree bark. It is often broken into small pieces, or sometimes ground into a grey powder. Magic mushrooms have a distinctive smell and taste, which most people find unpleasant. Occasionally it is available as fresh or semi-wilted whole mushrooms.
