Jacob Sullum on DUID Laws That Punish Unimpaired Pot Smokers



Last week, when the Colorado General Assembly passed groundbreaking legislation aimed at taxing and regulating marijuana, it also passed a bill redefining when cannabis consumers are considered too stoned to drive. The revised rule seems consistent with the voter-approved policy of treating marijuana like alcohol and therefore may be copied by other states that decide to follow Colorado down the path to legalization. But Senior Editor Jacob Sullum argues that the standard has little scientific basis and creates unfair legal risks for people who pose no threat to public safety.
