?These preliminary confessions, or introductory narrative of the youthful adventures which laid the foundation of the writer?s habit of opium-eating in after-life, it has been judged proper to premise, for three several reasons... ? Confessions of an English Opium-Eater (1821) is an autobiographical account written by Thomas De Quincey, about his laudanum (opium and alcohol) addiction and its effect on his life. 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. From its first appearance, the literary style of the Confessions attracted attention and comment. De Quincey was well-read in the English literature of the sixteenth and seventeenth centuries, and assimilated influences and models from Sir Thomas Browne and other writers.
