The Nature of Drugs: History, Pharmacology, and Social Impact, Volume 1, presents lectures from Alexander “Sasha” Shulgin’s popular course on what drugs are, how they work, how they are processed by the body, and how they affect our society. Transcribed from the original lectures recorded at San Francisco State University in 1987, The Nature of Drugs series highlights Shulgin’s engaging lecture style peppered with illuminating anecdotes and amusing asides. Ostensibly taught as an introductory course on drugs and biochemistry, these books serve as both a historical record of Shulgin’s teaching style and the culmination of his philosophy on drugs, psychopharmacology, states of consciousness, and societal and individual freedoms pertaining to their use, both medicinal and exploratory. The Nature of Drugs, Volume 1 features course lectures 1 through 8 and offers Shulgin’s view on the origin of drugs, the history of U.S. drug law enforcement, human anatomy, the nervous system, the range of drug administrations, varieties of drug actions, memory and states of consciousness, and research methods. It lays the groundwork for Shulgin’s philosophy on psychopharmacology and society. The Nature of Drugs series presents the story of humanity’s relationship with psychoactive substances from the perspective of a master psychopharmacologist and beloved luminary in the study of chemistry, pharmacology and consciousness.Audiobook note: The Nature of Drugs, Volume 1 audiobook contains portions of the original 1987 recordings of Shulgin himself conducting his course and interacting with his students. Those original clips are interlaced with newly recorded narration that fills in portions with more optimal audio quality.
