Caldwell, The Associated Press FINDING A NEW LEAF Attitudes Evolving Quickly Even As Concerns Are Raised WASHINGTON - It took 50 years for American attitudes about marijuana to zigzag from the paranoia of the Reefer Madness propaganda movie to the excesses of Woodstock back to the hard line of "Just Say No." The next 25 years took the nation from Bill Clinton, who famously "didn't inhale," to Barack Obama, who most emphatically did. Now, in just a few short years, public opinion has moved so dramatically toward general acceptance that even those who champion legalization are surprised at how quickly attitudes are changing and states are moving to approve the drug - for medical use and just for fun. It's a moment rife with contradictions: People are looking more kindly on marijuana even as science reveals more about the drug's potential dangers, particularly for young people. States are giving the green light to the drug in direct defiance of a federal prohibition on its use. Exploration of the potential medical benefit is limited by high federal hurdles to research. Richard Bonnie, a University of Virginia law professor who worked for a national commission that recommended decriminalizing marijuana in 1972, sees the public taking a big leap from prohibition to a more laissezfaire approach without full deliberation. "It's a remarkable story historically," he says. "But as a matter of public policy, it's a little worrisome." More than a little worrisome to those in the antidrug movement. "We're on this hundred-mile-an-hour freight train to legalizing a third addictive substance," says Kevin Sabet, a former drug policy adviser in the Obama administration, lumping marijuana with tobacco and alcohol. Colorado and Washington state are moving forward on their own with regulations covering everything from how plants will be grown to how many stores will be allowed. Tim Lynch, director of the libertarian Cato Institute's Project on Criminal Justice, predicts "the next few years are going to be messy" as states work to bring a black-market industry into the sunshine. Supporters of marijuana legalization range from libertarians who oppose much government intervention to people who want to see an activist government aggressively regulate marijuana production and sales. Opponents counter with a 2012 study finding that regular use of marijuana during teen years can lead to a longterm drop in IQ, and another study indicating marijuana use can induce and exacerbate psychotic illness in susceptible people. They question the notion that regulating pot will bring in big money, saying revenue estimates are grossly exaggerated. They reject the claim that prisons are bulging with people convicted of simple possession by citing federal statistics showing only a small percentage of federal and state inmates are behind bars for that alone. They warn that baby boomers who draw on their own innocuous experiences with pot are overlooking the much higher potency of today's marijuana. - --- MAP posted-by: Jay Bergstrom
