A bill was introduced at the state capitol on Monday that could make it illegal if a driver had more than 5 nanogram/millileters or more of THC (tetrahydrocannabinols) in their bloodstream. That person could be charged with DUI, a misdemeanor.
House Bill 11-1261 was introduced by Rep. Claire Levy (D-Boulder) and Rep. Mark Waller (R-El Paso County).
The Cannabis Therapy Institute says this is an attack on medical marijuana users.
The bill will be heard before a committee in the House.
