‘Jay’s sharp and playful intervention places psychoactive substances at the centre of the fin de siècle‘s psychological revolutions’   Washington Post

Psychonauts is a fascinating study of the cyclical attitudes towards self-experimentation with drugs’   History Today

‘Eye-opening…a welcome reconsideration of the role drugs play in life, medicine, and science’  Publishers Weekly

‘Psychonauts is a timely reminder that a prohibitive approach to drugs is not the historical norm’  Financial Times

‘Long before the hippies, a group of nineteenth-century artists, philosophers, and scientists began taking drugs in order to uncover the secrets of the mind. In Psychonauts, the historian Mike Jay argues that these thinkers were unique. Before the group’s experiments, drugs had been used to self-medicate, or to escape the world, but the psychonauts saw them as an education: a way to access the hidden corners of consciousness. In the process, they upended the notion of objectivity, asserting that drugs needed to be experienced in order to be understood. Jay has written several books on Western drug use, and his study is full of sharp, lively anecdotes’   New Yorker, Best Books 2023

‘Excellent…in these descriptions of travelling medicine shows, rowdy music hall acts, 19th century laboratories, the birth of psychoanalysis, the advent of modernism, the uncharted frontier of analgesia and anaesthesia and the demi-monde of Paris, we sense times which were in many ways more exciting and more revolutionary than the 1960s’   the Quietus

‘Breezy and profound, Psychonauts is a wildly entertaining history of drugs…a total blast’   Ben Westhoff

‘…a kaleidoscopic array of dense but fluid narratives, organized by substance and packed with colorful personalities, and collectively offering a crucial argument with significant implications: that psychoactives have played an absolutely central role in the experience and self-understanding of modernity.’  Erik Davis, Burning Shore

‘A fantastic book…highly recommended’   Nick Gillespie, Reason podcast (starts at 48:50)

‘Compelling…the history of mind-altering substances in the 19th century has been explained by Jay in an interesting, indeed compelling and sustained, narrative’  Irish Legal News
