The federal anti-drug campaign "Above the Influence" appears to have effectively reduced marijuana use by teenagers, new research shows. A study of more than 3,000 students in 20 communities nationwide found that by the end of 8th grade, 12 percent of those who had not reported having seen the campaign took up marijuana use compared to only 8 percent among students who had reported familiarity with the campaign.
