California: Lawmakers Shelve Bill To Impose Presumptive THC Impairment Standards

Posted by on August 26, 2016
Members of the Assembly Appropriations Committee have rejected legislation that sought to presume impairment in drivers with trace levels of THC in their blood. NORML wishes to thank those of who contacted your state lawmakers opposing this effort.

Assembly Bill 2740, sought to “make it an offense for a person who has 5 ng/ml or more of delta 9-tetrahydrocannabinol in his or her blood to drive a vehicle.”

The bill would have established a rebuttable presumption for this offense.

NORML is opposed to these proposed standards because the presence of low levels of THC in blood is an inappropriate and inconsistent indicator of psychomotor impairment. No less than the United States Traffic Highway Safety Administration (NHTSA) agrees, stating, “It is difficult to establish a relationship between a person’s THC blood or plasma concentration and performance impairing effects. … It is inadvisable to try and predict effects based on blood THC concentrations alone.” 

Separate Senate legislation that sought to expand the use of roadside oral swab testing was also tabled by lawmakers.
