Maine Lawmakers Reject Marijuana Blood Test Bill for Drivers

A Maine bill that would allow a blood test to determine whether a driver is impaired from marijuana use is heading to defeat.

The Maine House on April 1 voted unanimously to reject the bill, which set a blood level limit that would allow police to charge impaired motorists with operating under the influence.

Supporters say the blood test is needed for public safety, but opponents say there is no scientific consensus on impairment based on blood levels of THC, the psychoactive compound in marijuana.

The Maine bill sought to impose a 5 nanogram limit – the same as in Colorado and Washington, where recreational marijuana use is legal.
