This is Your Brain on Congress

Did I already post a pot story today? What was I talking about again? Well, anyway, here's one more, via the Agitator:

[Ohio's Representative Rob] Portman's proposal, so-called "zero tolerance" per se legislation, presumes individuals guilty of driving while intoxicated simply if trace levels of controlled substances or even drug metabolites (inactive compounds indicative of past drug use) are detected in their bodily fluids—even if the individual is neither under the influence nor impaired to drive. For anyone who enjoys an occasional toke from a marijuana cigarette, this news ought to be especially unsettling, as marijuana metabolites are often detectable in a person's urine for days or even weeks after the drug is consumed.
