Graduated driving laws reduce teen drunk driving

State laws that limit driving privileges for teens have reduced the incidence of drinking and driving among the nation’s youngest licensees, according to a new study from researchers at Washington University School of Medicine in St. Louis. Teens comprise less than 5 percent of licensed drivers in the country, but they account for roughly 20 percent of motor vehicle crashes.

Pregnancies more likely in teens who smoke, drink and use drugs

High school students who smoke, drink, use drugs or engage in other risky behaviors also are more likely to become pregnant or to impregnate a sexual partner, according to new research from psychiatry researchers at Washington University School of Medicine in St. Louis. And it wasn’t just one pregnancy. Those involved in risky activities had an even greater risk for multiple pregnancies.
