Among people aged 12 or older, 61.2 million people in the U.S. have used illicit drugs in the past year. People can misuse or become addicted to illegal drugs, like heroin, cocaine, or methamphetamine. They can also misuse and become addicted to prescription drugs, including opioid pain relievers and drugs that are intended to relieve anxiety, like Xanax. On the other hand, drugs such as caffeine, marijuana, alcohol, and prescription painkillers provide health benefits if not misused. Facts & Figures is one of ten titles in the Young Adult Drug Library series. It provides readers with the "big picture" regarding drugs, including their pros and cons; how they are made, distributed, sold, and used; why they are abused or misused; and treatment options for those who become addicted. The other titles in the series spotlight a major drug or type of drug (such as painkillers); discuss the negative physical and mental effects of the addiction on the addict and the potential benefits of their use (for certain legal drugs); and provide an overview of treatment strategies for the addiction. Stories of those who are battling drug addiction are also featured in order to humanize these issues.
