Singapore has 0.18 drug related deaths per 100k population. With a population of ~5.6 million people this means 10 deaths per year for whole country. In comparison Portugal has 3x higher drug related death rate.
Regarding executions you can check wikipedia:
> However, since the 2010s, execution has become far less common, with some years having no executions at all.
It displays that, the worse life is climate-wise, the more drug abuse there is.
Especially pronounced in Europe. As you go more inland and more to the north, drug deaths increase.
Is it a coincidence? Don't think so.
This way, Singapore was never in any danger, it's warm and coastal. And not in sub-Sakhara. Neither was Portugal, come to think of it! Thus it's a stretch to promote their solutions worldwide.

How did you get that from that chart? It clearly shows South Africa and Australia as having high drug-related deaths and they are as south as you can get.
A more accurate observation would be that developed countries with a heavy emphasis on individualism and a lack of communal culture experience the highest drug-related deaths.
Clean water tests would be a better example for your point. Or something to that degree. Less death rate could just mean other preferred drugs or even just cleaner ones.
