Colorado State Senate Rejects Attempt to Set THC Limit for Driving

Limit being proposed was arbitrary and very low

A stoned-driving debate that has divided Colorado lawmakers for years is poised to go down to the final hours in this year's Legislature.

With just two days left to settle the question, senators voted Monday to continue the driving-high debate by rejecting an amendment to say drivers are too stoned if their blood contains 5 nanograms per milliliter of marijuana's psychoactive ingredient, THC.
