I’d be worried about the ones charged with driving under the influence. It could easily be a way of profiling, given that there isn’t any objective way to prove someone’s high and not just having consumed within a couple days. The only current way that I know of is a field sobriety test, which can be a bit subjective.

You can do blood tests for THC, which are a reliable measure.
You are probably thinking of THC-COOH urine or saliva tests, which indeed will show positive for days or even weeks after you are already sober again, since THC-COOH is a metabolite of THC that takes very long to break down and does not have psychoactive properties
Just do it how Canada does it, they have a very reasonable cut-off value for THC blood concentration that even regular consumers with a tolerance for THC won’t surpass while sober again

You can, but did they in the cases in question?
Going forward, it’s a good thing that a method exists to test if someone actually is driving high.
