[Biological hallucinogens. New patterns of substance abuse in young addicts?].

Among young patients with multiple substance abuse, a high level of abuse of natural products was noticed. In a rehabilitation clinic for young addicts 180 patients filled out a questionnaire regarding drugs they regularly consumed. It was discovered that the patients consumed high levels of Psilocybe, Amanita and Datura. The natural drugs of the 70's, Ayahuasco and Cactus, are now rarely seen. The toxicological basis of the frequently used biological drugs is discussed. The results imply that a specific exploration of patients with multiple substance abuse in regard to the use of biological drugs is necessary.
