Might vary from region to region I guess. I’m in Europe and the following page indicates that it’s on Disney+ here currently https://www.disneyplus.com/en-gb/series/dopesick/vaEHfF8OZHU... but it might redirect for people in the US or say not available or something.
Also I don’t have Disney+ so I don’t know if the page applies to all of Europe even.
Edit: Yeah I tried to archive a copy of it and for archive.is it got redirected to the Disney+ home page so probably that’s what you will see too. Meanwhile, archive.org was able to capture it without being redirected. So whether the link will show info about the show or just redirect is probably region dependent. Those kinds of redirects are the most annoying btw. At least they ought to give a message like “this show is not available in your region”. Kind of surprised that archive.org didn’t get redirected actually – I had thought the servers archive.org used for capturing pages were in the US. And I thought archive.is were capturing from Europe.
Disney+ there is a kids section and the broader(not for kiddies) sections which has HBO, STAR world etc. Dopesick is in the [not for kiddies] section. This is in India, it maybe same in other regions.
