I actually am fine with drug legalisation. It should be legal for people with more than X acres of land (or people who rent X acres of land). You should be required to have a certified drug security person on staff that will deal with anyone who has a 'crisis' while using, and to especially make sure they don't leave the property to become a public nuisance. And you should be required to provide evidence of sufficient health insurance and coverage.

You should also have to prove that you will be able to maintain this lifestyle in perpetuity, perhaps by posting a sufficiently large bond with the state you're operating in, which can be re-funded to you if you can prove that you're no longer using permanently (I.e., maybe after a decade of no further use).

But if you do all that... please like bake yourself as high as you want and pay good taxes.

I have a substantial problem with people doing drugs in public. And having their trips on public streets.

But seeing as the requirements to safely do drugs are much stricter than most of what the 'typical' street drug user seemed to ever be capable of, I doubt decriminalizing all drugs in a safe manner will do much of anything. The irresponsible people will still be doing it. At some levels drugs will always be criminal, because they're anti social and humans don't like anti social behavior in general.
