Boulder Weekly, 09 May 2013 – Blood-Level THC Tests No Answer to Driving Safety HB 1325, which determines driving impairment through a blood-level THC test, was passed by the Colorado legislature on May 7. The bill says anyone caught driving with more than five nanograms of THC per milliliter of blood is considered impaired, with the caveat that one could argue that you weren’t impaired in court afterwards. Earlier versions – this is the sixth – made it an automatic conviction. Gov. John Hickenlooper is expected to sign the bill into law.
