At one time, in the U K, heroin was legal. It was generally restricted, if I understood correctly, for patients in the final stage of an illness, particularly cancer.

Televised news story showed British cancer patients medicated & able to do stuff like read, watch tv, enjoy crossword puzzles.

If heroin was restricted to those in severe pain & not responding to anything else—like end stage cancer—I’d be all for it in the U S.
