Thomas De Quincey 
Confessions of an English Opium-Eater 

Confessions of an English Opium-Eater (1821) is an autobiographical account written by Thomas De Quincey, about his laudanum addiction and its effect on his life. The Confessions was "the first major work De Quincey published and the one which won him fame almost overnight…" First published anonymously in September and October 1821 in the London Magazine, the Confessions was released in book form in 1822, and again in 1856, in an edition revised by De Quincey.

Thomas Penson De Quincey (15 August 1785 – 8 December 1859) was an English essayist, best known for his Confessions of an English Opium-Eater (1821). Many scholars suggest that in publishing this work De Quincey inaugurated the tradition of addiction literature in the West.
