Does kava count as a DUI?

Could you please clarify if consuming kava, a traditional Pacific Island plant-based beverage, would potentially lead to being charged with driving under the influence (DUI)? Is there any scientific evidence suggesting that KAVA consumption impairs one's ability to operate a vehicle safely, similar to alcohol or other intoxicants? Is there a legal precedent or guideline in place regarding kava consumption and driving? And if so, how is it enforced and what are the potential consequences?
