Positive school climate could work where drug tests don't

School drug testing does not deter teenagers from smoking marijuana, but creating a "positive school climate" just might, according to research reported in the January issue of the Journal of Studies on Alcohol and Drugs.An estimated 20 percent of U.S. high schools have drug testing; some target students suspected of abusing drugs, but often schools randomly test students who are going out for sports or clubs. The policies are controversial, partly because there is little evidence they work. And in the new study, researchers found no effects on high schoolers' drug experimentation.
