Singapore has not managed it by being a "much smaller state", it managed it by being a highly repressive and authoritarian state. Myself, I prefer the junkies on the streets.
I actually grew up in another relatively small state that had a huge heroin problem in the 80s: Portugal. Portugal solved it by decriminalizing drugs and by making treatment modalities available for the people who needed help, namely methadone. This worked spectacularly well.
By the way, if you want to make it "impossible to buy drugs without proper authorization", I imagine you will want to include one of the most dangerous hard drugs there is: alcohol. We all know how well that worked the last time it was tried...
Thank you for using this term instead of calling Singapore a dictatorship (as many others are wont to do). It's a much more accurate description of Singapore's style of governance.
