You still have a black market full of bad actors. That's the problem and that doesn't get solved. Those users of decriminalized drugs still have to go somewhere to get what they want.

Give them the drugs they need through the established channels, free of charge. Fentanyl is an extremely cheap drug when you cut the red tape. A large share - perhaps the majority - of these overdosing drug users were turned onto opioids by the medical establishment, which got away scot-free with malpractice.

You know that no one wants fentanyl? People want heroine, Oxys, xanaxs etc.

People are overdosing on fake drugs and relapses.
