D. M. Turner
D.M. Turner (born Joseph Vivian; 5 October 1962 – 31 December 1996) was an author, psychedelic researcher and psychonaut who wrote two books on psychoactives and entheogens. His first book, The Essential Psychedelic Guide, showcased his views on the subjective effects of various psychoactive and hallucinogenic mind-altering substances. His second book, Salvinorin, addressed the effects of Salvia divinorum. Turner died after injecting an unknown quantity of ketamine while in a bathtub, presumably drowning while incapacitated by the effects of the drug.
