* what constitutes "working", and
* "working" for whom?
The article makes it clear to me that the main problem is that since there are no criminal sanctions, there is less incentive to hide drug-taking activity. The streets are now cluttered with filthy, homeless fentanyl and meth addicts. Many right-thinking citizens are upset by how untidy it all looks.
What a surprise that not making an addict's life harder by locking them up has not magically led to them getting clean. The uptake on support services is not what one would hope.
Some people would like to return to criminalisation, presumably because "out of sight, out of mind". I think people with poverty, addiction and mental health problems should be given more support instead.
