Assembly Bill 2500 was introduced in February 2014, by Democratic Assembly Member Jim Frazier of Oakland. It was supported by the Association of Highway Patrolmen, the California Council on Alcohol Problems, the California Police Chiefs Association, the California State Sheriffs’ Association, among others. The bill was opposed by the ACLU, American for Safe Access, California Attorneys for Criminal Justice, California DUI Lawyers Association, California NORML, Crusaders for Patients Rights, Drug Policy Alliance, among others. The original text of the bill sought to impose a “zero tolerance policy” but the bill was amended to a “per se” standard.
Under the proposed law, drivers who have even a trace amount, (“2 nanograms, or more, per milliliter of whole blood”), of Delta-9-tetrahydrocannabinol, or THC, in their blood regardless of whether the person was impaired, could be charged with drugged driving. (Note, this bill also addressed drugs other than THC, providing a level of detectable metabolite that has to be present for the driver to be impaired; however, we are only going to discuss marijuana in this blog).
There is a huge problem with this standard: There has not been any studies proving a correlation of a certain level of THC in the blood and impaired driving. There simply is no science to back up the 2 nanogram standard and impairment. The result of such a law would criminalize non-impaired drivers! This is unacceptable and the California Assembly Committee on Public Safety correctly rejected the amended legislation.
