No, there is not. The driving case, the drivers actions, SFST's, and a blood draw to confirm the presence of marijuana are all crucial for a marijuana DWI conviction. They can be a pain to prosecute.
Alcohol DWI's are much easier to prosecute simply because of the breathalyzers and accurate blood draws. I have successfully prosecuted cases that were less than .08. It's call appreciable impairment.
