Study: Marijuana use causes brain dysfunction. Hey, man...whoa. Dys-what?

To the dismay of pot smokers who are still able to read to the study, The Journal of Neuroscience tamps out the fast-spreading notion that casual marijuana use does no harm. From the news report in the Washington Post:
A study in The Journal of Neuroscience says even casual marijuana smokers showed significant abnormalities in two vital brain regions important in motivation and emotion.
“Some of these people only used marijuana to get high once or twice a week,” said co-author Hans Breiter, quoted in Northwestern University’s Science Newsline. Breiter hailed the study as the first to analyze the effects of light marijuana use. “People think a little recreational use shouldn’t cause a problem, if someone is doing OK with work or school,” he said. “Our data directly says this is not the case. 
“This study raises a strong challenge to the idea that casual marijuana use isn’t associated with bad consequences,” he added.
Washington and Colorado have legalized the drug for recreational use, and 21 states and the District of Columbia permit medical marijuana use. Turns out the Rocky Mountain high may lower cognitive function. But if the study is correct, it may be too late now for Coloradans and Washingtonians to figure that out.
