DENVER (AP) — Colorado is considering setting a blood-test standard for what constitutes driving under the influence of marijuana.
It is illegal in all states to drive while impaired by drugs, but only a few states have set a measurable benchmark for how much marijuana you can have in your system to be charged with a DUI. The bipartisan proposal from Reps. Claire Levy and Mark Waller would set a limit of 5 nanograms of THC, the psychoactive marijuana ingredient.
The substance would have to be present within two hours of someone being pulled over.
Colorado's 5-nanogram proposal would be one of the most liberal in the country. Nevada and Ohio have a 2-nanogram limit.
Some medical marijuana advocates fear they'll be unfairly targeted, but Levy says the bill is about public safety.
