First published in the October 1917 edition of The International, Aleister Crowley's examination of cocaine and its role in society is a fascinating and important document in recreational drug history. Both "Cocaine" and Crowley's essay "Absinthe the Green Goddess," included here, serve as companion pieces to Crowley's other notable writings about his experimentation with narcotics, Diary of a Drug Fiend and The Psychology of Hashish.
