Parents play a major role in their children's choices about alcohol, tobacco or other drugs.

A recent national survey of parents and teens by the National Center on Addiction and Substance Abuse at Columbia University found one-third of teen partygoers have been to parties where teens are drinking alcohol, smoking marijuana or using cocaine, ecstasy or prescription drugs while a parent was present. By age 17, nearly half (46 percent) of teens have been at such parties where parents were present.
