Nev. lawmakers back blood-only detection of marijuana DUIs

CARSON CITY — Weighing in on how Nevada should test people for stoned driving, lawmakers advanced a measure on Friday to eliminate urine samples as a viable measure for police to show a driver to be impaired by marijuana.
Under the bipartisan proposal, law enforcement officers would continue using blood tests to prove a person was illegally operating a passenger car, commercial truck or boat while high.
The bill would retain specific legal limits set in 1999 for drivers’ blood content of THC, the psychoactive chemical in pot. Anyone with a blood-THC level at or above 5 nanograms per milliliter is considered too high to drive.
