The survey, designed to probe parents on their attitudes and practices related to teenage drug and alcohol use, also found that more than 90 percent of parents (92.2) say they would not allow their children to drink on prom night. But when faced with a teenager who said alcohol will be a part of the evening's celebration, most parents (32.9 percent) would allow their sons and daughters to stay out on prom night--but only after talking with them about the consequences. 19.2 percent would not allow their children to attend prom or prom activities if alcohol was going to be present. 16.4 percent would make sure their son or daughter took a limousine or had a ride to and from the prom so they would not risk driving after drinking.

Other survey results illustrate how parents claim to be strict but seem to be sending their children mixed signals. 94.5 percent of parents said they would not buy alcohol for their children's graduation parties if they were asked. At the same time, 11.4 percent of parents admit they do allow their children to have a drink at home.

The survey found that 56.6 percent of survey respondents said they talk to their children about this topic frequently. However, 65.4 percent of parents who participated in the survey said they tell their kids not to use drugs or alcohol and they are open about their use at their age. Parents can also influence their children by acting as a role model and drinking responsibly; 82.9 percent of survey response.
