Diary of a Drug Fiend was Aleister Croley's first published novel. To the reader of 1911 it presented a shocking look at a little known phenomenon. Today, while we are more familiar with drugs because of their widespread use in our culture, Diary of a Drug Fiend remains one of the most intense, detailed and accurate accounts of drug addiction and the drug experience.

The book was written by Crowley after years of deep personal study and experimentation with drugs. It is the story of a young man and woman who fall madly in love and whirl through Europe in a frenzied haze of heroin/cocaine adventure. Their ecstasy is brought to an abrupt end when their drug supply is cut off and despair replaces joy. Through the guidance of King Lamus, a master Adept, they free themselves from the entanglements of addiction by the application of practical Magick.

The narrative carries the reader aloft through the brilliance of the imagery created by this master of language; his prose development parallels the growth and increaing depth of his characters in an uncanny fashion. This is a book to be read and reread. It will also prove a useful document to doctors, lawyers, police and addicts for its unique and precise presentation of the psychology of addiction and the possibility of its cure through the development of the True Will.
