Heroin will not benefit society, the hypothesis is that it will cause less harm if users receive it from a boring, official, controlled source instead of letting violent criminals earn millions with it. The idea that prohibition can somehow end drug use was proven wrong a long time ago.

I would not necessarily credit Heroin for it (and would definitely not advocate its use), but a sizable proportion of Rock and Jazz performers have composed and performed music under its influence.
