Entertaining... Tripped is a story of front organizations, dodgy funds, bizarre experiments, assassinations, scientists, magicians, hookers, and spies. - The Times

A brilliant exposé of how Dr Albert Hofmann's epic discovery of LSD got lost in the ensuing war on drugs and the corollary, its misuse for mind-control, that hurt him personally and has hampered investigation into the potential therapeutic and spiritual benefits of the pharmaceutical -- Professor Carl Ruck, author of The Road to Eleusis

"Nazis, Big Pharma, and American special agents, oh my!" Ohler takes the reader on a journey down some of the lesser-known dark alleys of psychedelic history. From promising medical treatment to weapons of war and criminal nuisance and back again, Tripped recounts some of the hidden origins behind the rise and fall (and subsequent rebirth) of research into LSD and similar substances. An engrossing read, full of mystery and intrigue. -- P.W. Barber, author of Psychedelic Revolutionaries

Utterly fascinating and illuminating. In tracing the curious origins of LSD as a drug and as a cultural phenomenon - a compulsive maze-like trail that takes in obscure Swiss institutes, the rise of Nazi Germany, the philosophy of brainwashing, CIA conspiracies, the White House and Elvis Presley - Norman Ohler also cleverly throws fresh light on the Cold War that dominated the late twentieth century: a global struggle for psychological supremacy and psychic liberation. On top of all this, his storytelling is not only beguiling but - by the end - profoundly moving as well. It is possible that LSD will have a part to play in all our medical futures: this gripping and deeply felt book will tell you why -- Sinclair McKay, author of Berlin

A fascinating book about the battle for LSD, which shines a light on the relationship between antagonistic powers, secret services and the medical industry. An astonishing read, with remarkably vivid protagonists. -- Harald Jähner, author of Aftermath
