Decriminalisation alone won't improve what you're talking about. But the idea usually is decriminalisation plus redirecting those freed up funds into policies for harm reduction, addiction treatment, injection rooms etc. Reframing it as a public health issue not a criminal issue. The only example I know of is Portugal.
