Phantastica: Die Betaubenden und Erregenden Genussmittel

First edition of the psychedelic classic by German pharmacologist Louis Lewin (1850-1929). Set the standard for the classification of psychoactive drugs: Inebriantia (Inebriants such as alcohol or ether), Excitantia (Stimulants such as Khat or Amphetamine), Euphorica (Euphoriants and Narcotics such as Heroin), Hypnotica (Tranquilizers such as Kava), Phantastica (Hallucinogens or Entheogens such as Peyote or Ayahuasca). Later translated into French, Italian, and English, the 1931 English edition said to be Aldous Huxley’s introduction to drug literature.
