Marijuana DUI Bill Clears Big Colorado Hurdle
Colorado State Senator Nancy Spence changed her vote in favor of driver impairment set at 5 nanosgrams or more of THC
A marijuana blood standard for drivers appears headed for approval in Colorado — thanks to a single vote change from a Republican senator. Sen. Nancy Spence of Centennial voted Tuesday in favor of the plan to consider drivers impaired if they test positive for 5 nanograms or more of THC, the psychoactive ingredient in marijuana, per milliliter of blood.
Spence’s decision gave the bill the support it needed to advance on a vote of 18-17 after an emotional debate. Driving while impaired by marijuana or any drug is already illegal, but supporters of the THC blood limit say law enforcement needs an analogous standard to the blood-alcohol standard to keep stoned drivers off the road.
