LSD is an illegal psychedelic with a bizarre background. Startling evidence shows that scientists and psychiatrists have helped to promote its use Engaging, articulate, and brilliantly argued, On Drugs is destined to become a revolutionary classic that redefines what it means to be "high".

In advocating "a diversity of consciousness," David Lenson forges a new look at the drug debate from a lost, and often forbidden, point of view: the user's. Describing in clear detail the experiences and dynamics of the drugs of pleasure and desire -- from nicotine to marijuana, alcohol to LSD, and caffeine to cocaine -- On Drugs asks what drugs really do and challenges society's accepted notions of sobriety and addiction.
