The economists' review of national and state surveys and drug tests showed no correlation between an uptick in recent teen drug use and the increased availability of pot. The best numbers available don't show any greater use in states that have legalized medical-marijuana dispensing, CU Denver economist Daniel Rees said. "There's just not a whiff of an increase" in states with more liberal marijuana laws, Rees said. "If anything, it goes down." Critics pointing to an increase in teen drug use will have to look harder for valid causes, he said. The U.S. Attorney's Office in Denver said it had not yet read the full study but added it is concerned about other surveys showing a rise in marijuana use by Colorado teenagers. The White House's Office of National Drug Control Policy criticizes medical marijuana's spread and draws connections with youth drug use. Rees and economists from Montana State University and the University of Oregon combed wide surveys from 1993 to 2009. In those years, 13 states (including Colorado) legalized marijuana for medicinal uses, with varying access to dispensaries. The data included surveys of high school behavior, as well as drug-test screens from patients entering federally funded drug-treatment centers. - --- MAP posted-by: Jay Bergstrom
