Sen. Hickenlooper Calls for a Federal Impairment Standard for Driving While High

Sen. John Hickenlooper (D-Colo.) is looking for clarification about a federal standard regarding THC impairment while driving. "I think in terms of marijuana, the fact that it's still a Schedule 1 narcotic — it's treated the same as heroin and cocaine — it means that we can't get standards developed," he said about the lack of cohesive regulations. The lawmaker also explained his previous opposition to cannabis legalization in Colorado when he was governor and why his position changed.
