CHICAGO (AP) — Kids on both sides of the Atlantic are smoking less pot and going out less often with friends at night, a study of 15-year-olds in 30 countries found. The double declines occurred in the United States, Canada and mostly European countries from 2002 to 2006. The trends are likely related, because other research has found that kids who spend many evenings out are more likely to smoke dope than homebodies. Teens are most likely to use the drug secretly away from home, said lead author Emmanuel Kuntsche.——Contact the news staff at [email protected]
