This fully updated, no-judgment book includes the up-to-the-moment discoveries about drugs and drug use, including new information on the opioid crisis, vaping, psychedelic therapy, cannabinoids and the science of addiction. "Lively, highly informative, unbiased, [and] thorough" (Addiction Research & Theory), Buzzed surveys drugs from caffeine to ketamine to reveal how they impact the body, the different effects they produce and the circumstances in which they can be deadly. In an environment rife with myth and misinformation, this book is a must-read for anyone seeking the facts on our ever-changing drug landscape. Neither a "Just Say No" treatise nor a "How to" manual, Buzzed is based on the conviction that people make better decisions with the best available information at hand.

The first edition was praised as:

• "Buzzed is one of the most important books I've ever read..." - Irvine Welsh, author of Trainspotting
• "A unique, up-to-date, and useful source for all those interested in the workings of and effects of legal and illegal drugs, regardless of whether you are a concerned mother or Irvine Welsh!" - The British Psychological Society
