Singapore has also upheld imprisoning people for homosexual acts in recent years. It is not a society that tolerates behaviour outside the mainstream.

The death penalty is for dealing, not for users.

The quantities listed in https://en.wikipedia.org/wiki/Capital_punishment_in_Singapor... seems higher than what a user would have on them.

Possession of large enough a quantity means you're automatically considered a dealer, and we're not talking huge quantities either: 30g (1 oz) of cocaine translates to a mandatory death penalty. This extends to things like having the key to a locker containing drugs.

Yes. And I wish they would move to a policy of legalise-and-regulate-(-and-tax).

But at least they manage to make their prohibition policy actually effective: drugs are hard to get, and not a lot of people are actually behind bars or executed for trading.

(Compare with eg the US which incarcerates a lot of people, but the drug trade goes on regardless.)
