The reality is we’re at the limit of technical knowledge. The tests are super sensitive, and the experts can’t agree on a level of thc that accurately reflects impairment because it’s not as consistent as alcohol.

I’d suggest we structure our laws so it’s only a dui if the person fails and impairment test and a drug test. If they pass the impairment test they should be off the hook. But I don’t believe we should be enabling more DUI because of how much damage they can do
