A marijuana blood limit for drivers was rejected Monday for a fourth time in the Colorado Senate, where bipartisan skepticism on the pot analogy to blood-alcohol limits helped sink the measure even in a weaker form.
The Senate Judiciary Committee voted 4-1 to reject the blood standard after a long hearing that has become something of an annual tradition in the Senate: reviewing the scientific basis for using marijuana content in blood to determine whether a driver is stoned.
“This is a significant public safety concern,” said Matt Durkin, a state assistant attorney general and supporter of the bill, which would have limited drivers to 5 nanograms per milliliter of blood for THC, pot’s psychoactive ingredient.
Durkin worried that recreational pot use will spike because of last year’s vote to defy federal drug law and declare marijuana OK in small amounts for people older than 21.
Washington state also voted to legalize pot last year, but voters there included a 5-nanogram driving limit for impairment cases.
