DENVER - A bill creating a legal limit for driving while under the influence of marijuana has passed a second reading in the State Senate.
The bill sets a standard of 5 nanograms or more of delta 9-tetrahydrocannabinol per milliliter of whole blood. The level of intoxication would be determined by a blood test.
The bill also allows police officers to require drivers who possess a medical marijuana registry card to submit to a blood test.
The legislation, designated House Bill 13-1325, also passed a second reading in the House last week.
