Lauren Slater offers an explosive account not just of the science but of the people--inventors, adherents, detractors, and consumers-behind our licensed narcotics, from the earliest, Thorazine and Lithium, up through Prozac, Ecstasy, 'magic mushrooms,' the most cutting-edge memory drugs, and neural implants. In so doing, she narrates the history of psychiatry itself and illuminates the signature its colorful little capsules have left on millions of brains worldwide, and how these wonder drugs may heal or hurt us.
