Arizona Marijuana DUI vs Alcohol DUI: Identical Penalties, Different Battles

Proposition 207‘s legalization of recreational marijuana fundamentally changed how Arizona prosecutes cannabis DUI cases. While the penalties for Arizona marijuana DUI vs alcohol DUI remain identical, the path to conviction—and your defense options—differ dramatically.

The Legal Framework for Arizona Marijuana DUI vs Alcohol DUI Post-Proposition 207

Critical Change: Marijuana DUI is now solely prosecuted under A.R.S. § 28-1381(A)(1)—the same impairment statute as alcohol (impairment to the slightest degree)—requiring proof you were “impaired to the slightest degree.”

This is where the State runs into significant problems in seeking convictions based only on the presence of the active component of THC.
