How many of our teens actually smoke, drink, and take drugs? And what kinds of drugs and tobacco products are they using?
That's what the University of Michigan and the National Institute on Drug Abuse seek to learn in their annual surveys of 40,000 to 50,000 teens in grades 8, 10, and 12.
The latest Monitoring The Future survey was released today.
Lloyd Johnston, the principal investigator for the project, joined us today. He’s with the University of Michigan's Institute for Social Research.
