The biggest risk to a teenager's health isn't any single disease. The biggest risk comes from unintentional injuries. Alcohol and drugs play a big role in increasing a teen's risk of injury, because they lower inhibitions, increasing the willingness to take risks while decreasing the coordination and reaction time needed to respond to emergencies. The National Clearinghouse for Alcohol and Drug Information says a teenager may drink for any number of reasons, including peer pressure, boredom, or depression.
Teens are also susceptible to advertisements for beer and wine coolers.
If a teen or parent is concerned about alcohol use or abuse, a school counselor or your healthcare provider should have information on getting professional help. Perhaps the best time to seek information, however, is even earlier. The American Academy of Pediatrics says it's essential for parents to start talking to their children at an early age about the dangers of alcohol use or abuse. Parents should also be aware of potential warning signs of drug use including behavior changes, sudden hostility, withdrawal from friends and family, or marked changes in school performance and attendance. Teens are also at a higher risk of injury on the road.
