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.
