Warning on 3 and 5. The UK destroyed records of immigrants who were invited over to help rebuild Britain postwar and their children. Then a racist Conservative government deported a bunch of them who were children in the 1940s and didn't have proof of legal immigration status - the only legal documentation had been destroyed. These now old people were dumped back in the Caribbean having lived in the UK for almost their entire lives. It was brutal.
Yup, the only ones he didn't pardon were the ones with "intent to distribute", and those should probably be pardoned, and those driving under the influence, who maybe shouldn't.
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
