The essential source for understanding how drugs affect the body and behavior. Fully updated, this matter-of-fact handbook includes the most recent discoveries about drug use, including new information on electronic smoking devices, abuse of prescription stimulants, and the opioid crisis. "Lively, highly informative, unbiased, [and] thorough" (Addiction Research & Theory), Buzzed surveys drugs from caffeine to heroin to reveal how these drugs affect the body, the different "highs" they produce, and the circumstances in which they can be deadly. Neither a "Just Say No" treatise nor a "How to" manual, Buzzed is based on the conviction that people make better decisions with accurate information at hand.
