This is just about the worst example you could have used for your theory. In this case there are thousands of people that could have just done a 1:1 copy of what they do in Switzerland, Portugal, Netherlands, Scandinavia etc. Instead they copied only the carrot (treatment and harm reduction). Then they didn't just not copy the stick (prison, consequences for missing treatment) they threw away all their sticks.

With this in mind I can understand why many people are now against harm reduction of any kind, when the same people that fucked it all up in the first place now want to try again.
