California Assemblyman Proposes Marijuana Zero-Tolerance DUI Standard

Posted by Jon Ibanez on April 11th, 2014

We recently referred you to an American Bar Association Journal article in which Lawrence Taylor was interviewed about the difficulties of correlating traces of marijuana in the blood and intoxication. We also mentioned the use of zero-tolerance laws for marijuana by some states as a way to address issue. It seems that one California assemblyman looks to include California in that list of zero-tolerance states.

Currently, for a person to be convicted of a California marijuana DUI, it must be proven that they were “under the influence.” A person is under the influence when his or her physical or mental abilities are impaired to such a degree that he or she no longer has the ability to drive a vehicle with the caution characteristic of a sober person of ordinary prudence under the same or similar circumstances.

Assemblyman Jim Frazier recently introduced AB 2500. The bill, if passed, would change California’s current DUI law making it unlawful for a person to drive with any detectable amount of marijuana in the system. The law also seeks to make it illegal to drive with any trace of any other controlled substance in the system.

The proposed language of the law would read:

“It is unlawful for a person to drive a vehicle if his or her blood contains any detectable amount of delta-9-tetrahydrocannabinol of marijuana or any other drug classified in Schedule I, II, III, or IV under the California Uniform Substances Act (Division 10 (commencing with Section 11000) of the Health and Safety Code).”

The legislature rejected a similar bill introduced last year by Senator Lou Correa. Rightly so. Let’s hope they do the same to AB 2500.

Delta-9-tetrahydrocannabinol (THC) can remain in a person’s blood for up to weeks and longer after marijuana use, and well beyond the point at which a person cannot safely operate a vehicle. That doesn’t matter to those who support the proposed law. It seems they would be okay with punishing perfectly sober drivers simply because they ingested marijuana at some point in the last several weeks.
