Quincey attempted to address this type of criticism. When the 1821 original was printed in book form the following year, he added an Appendix on the withdrawal process; and he inserted significant material on the medical aspects of opium into his 1856 revision. More generally, De Quincey's Confessions influenced psychology and abnormal psychology, and attitudes towards dreams and imaginative literature. Edgar Allan Poe praised Confessions for its "glorious imagination—deep philosophy—acute speculation". The play The Opium Eater by Andrew Dallmeyer was based on Confessions of an English Opium-Eater, and has been published by Capercaillie Books. In 1962, Vincent Price starred in the full-length film Confessions of an Opium Eater, which was a reimagining of De Quincey's Confessions by Hollywood producer Albert Zugsmith. In the 1999 documentary Tripping, recounting Ken Kesey's Furthur bus and its influence, Malcolm McLaren refers to De Quincey's book as the influence for the beatnik generation before Jack Kerouac's popular On the Road was written. The book has been parodied in the Elder Scrolls series with the book Confessions of a Dunmer Skooma Eater, which first appeared in The Elder Scrolls III: Morrowind.
