Many stories have been told about "tripping" on absinthe. Sorry to say, not only is absinthe not an hallucinogen, the chemical thujone, that is barely present in both vintage and modern absinthes, is more of a convulsant. That is not Absinthia's idea of a fun evening!The terrifying hallucinations reported in early, hospitalized absinthe abusers were most likely due to the withdrawal symptoms of acute alcoholism: alcoholic hallucinosis, or, the DTs.  While some of the botanicals used have a mild stimulant effect (aniseed and fennel), there are no psychedelic or hallucinogenic ingredients in authentic absinthe, now or in the past.
