[The effect of hallucinogenic drugs on the development of psychoses]

Psychotic behavior and suicide which occurred after it induced us to study a connections among LSD use, psychotic behavior and suicidal risk ones again. Hereby we have a case of a young man who showed a psychotic behavior a week after taking LSD which ended tragically with suicide. What was the cause of this action, was it a late consequence of drug intake, flush-back or the first episode of a dissociative process which possibly started by change of behavior and sphere of interest? It is hard to answer this question by psychological autopsy. The dilemma remains constant, but we still think that this case report is of importance because we must not neglect such a clinical picture after taking LSD. It is particularly important now as drug addition is abruptly increasing in our society.
