Senator Chuck Grassley (R, IA), ranking member of the Judiciary Committee and co-chair of the Caucus on International Narcotics Control, expressed concern about the findings of the 2014 Monitoring the Future Survey (http://www.monitoringthefuture.org). The survey, funded by the National Institute on Drug Abuse, measures drug use and attitudes among 8th, 10th, and 12th graders.
While the use of marijuana appears to have leveled off, the 2014 survey found, most high school seniors do not think smoking marijuana occasionally is harmful, while only 16.4% said it puts users at greater risk. In 2009, 27.4% of 12th graders said they thought smoking marijuana occasionally put users at greater risk (http://bit.ly/17jR94k).
