A bill setting an impairment standard for driving under the influence of marijuana is getting its first hearing in the Colorado Senate.
The proposal would set a blood-content threshold that would allow prosecutors to charge drivers believed to be under the influence of marijuana. Drivers would be considered too high to drive if they have a THC level of 5 nanograms or more per milliliter in their blood. THC is the psychoactive ingredient in marijuana.
That level THC blood-content level would be the most liberal in statute in the country but it has angered some medical marijuana users who fear they’ll be unfairly targeted.
It’s illegal in any state to drive while impaired by drugs. Nevada and Ohio have a 2 nanogram THC limit for driving.
