This entry covers entheogens in the strict sense of the word (i.e. psychoactive substances used in a religious or shamanic context). For general information about these substances and their use outside religious contexts, see psychedelics, dissociatives and deliriants.An entheogen, in the strictest sense, is a psychoactive substance (most often some plant matter with hallucinogenic effects) which occasions or supplements a spiritual/mystical experience. In a broader sense, the word "entheogen" refers to artificial as well as natural substances which induce alterations of consciousness similar to those documented for ritual ingestion of traditional shamanic inebriants, even if used in a secular context.
