What effect does peer pressure have on drinking?

Peerpressure=alcohol. The adolescent substance abuse knowledge base reports 30% teens are offered drugs in middle- high school. According to the national household survey on drug use and health from the U.S. Department of health and human services, 74.3% of high school students have tried alcohol. To combat 'peer-pressure' parents should 'talk to their teenagers', know their friends and stay involved.
