When it comes to drugs, alcohol and tobacco use, how do teens in this country compare to those in Europe?

A survey of about 100,000 15 and 16-year-olds in 35 European countries – along with teens in the U.S. – finds American teens use more illicit drugs than teens in Europe according to University of Michigan researcher Lloyd Johnston.

“Thirty-one percent of the American students have used cannabis in their lifetime, and about half that, 16 percent, in Europe. So that's a fair difference,” he says.

But when it comes to cigarette smoking and alcohol use, the American teens had the lowest use of any of the countries.
