You’re kind of missing the point. You’re correct on principle but the issue is how to actually regulate it and create laws around it. Im totally in favor of media campaigns with that point, it is a north star. Thats what they actually do in California. Still, someone can be .02 BAC and be be fine to drive. I’m sure there’s some alcoholics that can be over .08 and pass a coordination test, due to their tolerance. The .08 is the law for a good reason though.

The only way to do that for thc would be a blood test, to the best of my knowledge. I don’t think that’s practical. The answer is definitely NOT police discretion though.

I don’t know for sure but it must be state laws. I believe Georgia has has laws against it I know California does. It really creates so much needless nonsense and it would require the US congress to fix but the GOP has made that entire branch of government, practically, non-functional.
