Ketcham and Pace present an honest and factual look at the problem of teenage substance abuse. Ketcham worked on Under the Influence (2002), and Pace is the founding director of the American Council on Drug Education. In Teens Under the Influence, they team up to offer a valuable resource for parents whose children are already abusing drugs and alcohol, and to those who want to prevent their kids from ever using. The book is honest and thorough, with a detailed chapter on each drug and how it works. The authors even explain what each drug's high is like (e.g., "cocaine increases brain levels of the feel-good chemical dopamine" and usually makes a user hyperactive, impulsive and talkative). The book's final section gives detailed instructions on how parents can intervene and walk their children through the rehabilitation process, including relapses.
