A national study of teenagers suggests that school drug testing did not deter them from starting to smoke tobacco or marijuana or drink alcohol. But in high schools that had a “positive school climate,” teens were less likely to start smoke cigarettes or marijuana, according to the study, in the January issue of the Journal of Studies on Alcohol and Drugs. The study compared the effectiveness over one year of school policies of student drug testing with a positive school climate.
