Yes, you can be arrested for a DUI involving marijuana in California. Even though cannabis is legal, it is still illegal to drive while impaired by any drug, including THC.
However, a marijuana DUI is very different from an alcohol DUI. Unlike alcohol, there is no clear legal THC limit that automatically proves impairment. THC can remain detectable in blood or urine long after any intoxicating effects have worn off.
Just because law enforcement arrests you for a weed DUI and prosecutors file charges — does not mean a conviction is inevitable. These cases often rely on subjective observations, field sobriety tests, and chemical results that can be challenged.
If you are facing a marijuana DUI charge in Orange County, an experienced DUI attorney can review whether the stop was lawful, whether impairment was actually proven, and whether testing results are reliable.
