(Reuters) - U.S. teenagers are smoking more marijuana but backing away from other harmful drugs and doing less binge drinking, according to a report from federal health researchers released Wednesday. Easier access to marijuana provided by new state laws allowing the drug for medical treatment might be a factor, according to the report from the National Institutes of Health. The survey found that roughly 6.5 percent of high school seniors are smoking marijuana daily, compared with 6 percent a decade ago and 2.4 percent in 1993, and nearly 23 percent of seniors said they smoked the drug in the past month. About 4 percent of 10th graders said they smoke the drug daily, and 18 percent said they did within the past month. "We should be extremely concerned," said Nora Volkow, director of the National Institute on Drug Abuse. The growing use parallels an increase in the potency of marijuana, so the drug can be even more harmful to developing brains than in the past, Volkow added. More teens are smoking marijuana in part because they see less risk from regular use, according to the "Monitoring the Future" survey. Slightly less than 40 percent of 12th-graders surveyed said they see regular marijuana use as harmful, down from 44.1 percent a year ago, the report said. Researchers said many of the teens reporting regular marijuana use say they get the drug through a medical marijuana prescription, either written for themselves or someone else. Colorado and Washington state have legalized recreational use of marijuana, while 19 other states and the District of Columbia permit some form of medical marijuana use. A separate study also out Wednesday underscored how legalization can translate into increased use. Washington state residents will consume an estimated 175 metric tons of marijuana this year, equivalent to about 50 half-gram joints for each man, woman and child in that state, according to a study commissioned by state officials. - --- MAP posted-by: Matt
