The study qualifies the pot statistics by emphasizing that because marijuana stays in the blood for up to one week, therefore, researchers said, "the prevalence of nonalcohol drugs reported in this study should be interpreted as an indicator of drug use, not necessarily a measurement of drug impairment."

The studys conclusions have nothing to do with the title of the article. Also any test for pot will show for 30 days not the 7 stated in the article. Did Michael Mann write this??
