Those, from what I understand, don’t hit the same and someone needs to be ready to quit to go on them, they help with withdrawal etc, definitely, but are not always successful as they don’t scratch the full itch. A bit like nicotine replacement therapy

But there’s a whole space of harm-reduction before then, which is where things like the Swiss program to provide heroin in controlled circumstances can fit in.

An opioid without respiratory depresses on problems could fit into that sort of thing pretty well.
