Constantly having to remind them of rules from session 0, such as 'no alcohol before or during the game'
That sounds like the most boring DnD session ever, we get so high that any underlying condition is masked by having a damn good time. ;)

Similarly, I'm aware some people cannot behave or function on other drugs such as alcohol (same for me). I wouldn't say others aren't allowed to drink but I don't want to smell cigarettes or cannabis. Smelling alcohol does nothing to me (obviously?)
So it boils down to constructing a social agreement based on consensus. Something which works for everyone. Which is more difficult the more people on the spectrum are there, and the less flexible other players are regarding their quirks.
So if the consensus is sober, be sober or don't join the team. Quite a simple concept. What happens here is that boundaries aren't respected (common with people on the spectrum). Explain the issue and (possible) consequences.
I'm glad that works for you, but I've both tried playing D&D while high, and had some players who'd get high, and it was not particularly pleasant. In my experience, D&D requires more clarity of mind than marijuana tends to leave you with.
And I say this as someone who's going to start drinking less during D&D games, because I've noticed that after my third beer, my DMing is not as good as it is after my first beer.
