Marijuana beat out cocaine, heroin, methamphetamine and hallucinogens to take the top spot in the first-ever global survey of illicit drugs. The study by Institute for Health Metrics and Evaluation at the University of Washington also showed that doctor-prescribed painkillers such as Vicodin and Oxycontin were the deadliest of all drugs. The survey, published online Thursday in the journal Lancet, showed that more than half of the estimated 78,000 deaths worldwide from drugs in 2010 were caused by pain pills. "Even if it is not very solid data, we can say definitely that there are drug problems in most parts of the world," said Theo Voss, senior author of the study. The United States, Britain, Russia and Australia had the greatest drug problems, the study showed. "The illicit use of prescribed opiates in the U.S. has only happened in the last 10 years or so," said Michael Lynskey, of the National Addiction Centre at King's College London. "It's possible in another 20 years, patterns will again change in ways we can't predict," Lynskey said. The survey didn't explain why pot is globally so popular, but it comes just days after researchers in the Netherlands found tokers' responded to negative images or emotions in a more positive way when stoned. A University Medical Center Utrecht study found that THC, the mind-altering ingredient in marijuana, was beneficial to the emotion-processing cerebral regions of the brain. "THC administration reduces the negative bias in emotional processing," the report, published this week in the European Neuropsychopharmacology journal, concluded. Meanwhile, the Obama administration announced Thursday that it won't sue to challenge laws legalizing marijuana in 20 states. The Justice Department said states are allowed to let people use weed and license farmers to grow it as long as its kept away from children and off the black market.
