transtornos due to uso of hallucinogens are characterised by the padrão and consequences of hallucinogen uso. Several thousand compounds have hallucinogenic properties, many of which are found in plants (e.g., mescaline) and fungi (e.g., psilocybin) or are chemically synthesized (e.g., lysergic acid diethylamide [LSD]). These compounds have primarily hallucinogenic properties, but some may also be stimulants. Much of the morbidity associated com these compounds arises from the acute effects related to Hallucinogen intoxicação. Hallucinogen dependência is rare and Hallucinogen abstinência is not described. Among the mental transtornos related to hallucinogen uso, Hallucinogen-Induced Psychotic transtorno is the most frequently seen, although worldwide it is still fairly uncommon.
