Pubdate: Thu, 15 Dec 2011 Source: Denver Post (CO) Copyright: 2011 Los Angeles Times Contact: http://www.denverpost.com/ Details: http://www.mapinc.org/media/122 Author: Shari Roan, Los Angeles Times EXPERTS: TEEN USE OF POT ON THE RISE LOS ANGELES - Fewer teens drink and smoke cigarettes than in any time in the past 30 years, but the widespread availability of medical marijuana appears to be fueling a rise in pot use, health experts said Wednesday. One in four of the 47,000 teens surveyed for the 2011 Monitoring the Future report said they had used marijuana at some point during the past year, up from 21.4 percent in 2007. The survey, which polled students nationwide in the eighth, 10th and 12th grades, also found that one in 15 of the oldest students used pot on a daily or near-daily basis - the highest rate since 1981. For the first time, researchers asked 12th-grade students about synthetic marijuana, which contains cannabinoids and produces a high similar to pot but is thought to be more dangerous because it can be contaminated with unknown substances. The finding - 11 percent of all high school seniors had tried the substance - surprised researchers. Sold by the names Spice or K2, the drug has been widely available online and in tobacco shops until recently. In February, the Drug Enforcement Administration reclassified some of the chemicals found in the products as Schedule I controlled substances, which made them illegal. The survey also revealed that teens don't think of marijuana as dangerous. Because of that, "we can predict that use of marijuana is going to increase," said Dr. Nora Volkow, director of the National Institute on Drug Abuse?, which funds the annual study. That pot has become more widely used as more states legalize the use of medical marijuana legalization cannot be ignored, said R. Gil Kerlikowske?, director of the White House Office of National Drug Control Policy. "We know that any substance that is legally available is more widely used," he said. The rise of marijuana is largely responsible for an overall increase in youth drug use over the past four years, said study leader Lloyd D. Johnston of the University of Michigan's Institute for Social Research, which conducts the annual survey. When marijuana is taken out of the equation, the proportion of teens reporting they had used any illicit drug declined through the first half of the 2000s and has been stable over the past three years. Since 1991, the proportion of eighth-grade students who said they used alcohol within the past 30 days has declined by half, to 13 percent, the survey found. Rates have also fallen in older students, with binge drinking among seniors dropping from 41 percent in 1981 to 22 percent this year. Still, about 40 percent of high school seniors say they have used alcohol within the past 30 days. Cigarette use fell in all three age groups, which was reassuring because the 2010 survey hinted that the decades-long decline in smoking may have begun to reverse, Johnston said. In all three grades combined, 11.7 percent of youths said they smoked within the past 30 days, down from 12.8 percent in the 2010 survey. Declines were also seen in the use of inhalants, crack cocaine, the painkiller Vicodin, the attention deficit hyperactivity disorder drug Adderall and over-the-counter cold and cough medicines. Use of prescription drugs without medical supervision remains a concern. In 2011, 22 percent of high school seniors said they had misused at least one prescription drug, the same rate recorded in the 2007 survey. - --- MAP posted-by: Jay Bergstrom
