Why do some teens become addicted to alcohol? Called a “gateway drug,” alcohol usually leads on to other drug use. Kids often begin drinking in their preteens, sometimes as young as nine or ten years of age. Their addiction hardens into their teenage years, wreaking havoc on their studies and on their lives. In our continuing Health Dialogues series, host Larry Mantle speaks with Dallas Stout, the managing director of the Phoenix Academy of Orange County, a drug and alcohol treatment facility, and Kenneth Peter, resource teacher for safety, drugs alcohol, tobacco, health and Physical Education in the Pasadena Unified School District. Also joining Larry are Gina, a resident in the Phoenix Academy's recovery program, and Dr. Susan Tapert, an assistant professor of Psychology at the University of California, San Diego, who studies the physiological effects of alcohol on teenagers’ brains.
