For adults the ingestion of hallucinogenic mushrooms is often intentional and is actively pursued, leading to the widespread cultivation of this species, Psilocybe cubensis or Stropharia cubensis. The experience is generally pleasurable and, compared to LSD, is short-lived, lasting 5 to 6 hours. Flashbacks are rarely reported, though confidants have reported terrifying experiences and in very, very rare cases have experienced the precipitation of mental crises requiring subsequent extensive psychiatric treatment. What will happen after consumption of the mushrooms is strongly dependent upon the setting and the mood as well as psychological make-up of the individual. Psilocybe cubensis is very variable in potency, generally ranging from 0.1% to 0.5% active ingredients by dry weight. Furthermore, what you buy on the street may be mushrooms adulterated with some other drug; consequently the effects and treatment needed are highly variable.
