Singapore and Australia might also be on the list.
Sure, Singapore has draconian laws when it comes to narcotics. But surely everyone attending will be aware of this? It’s been widely reported over the decades how foreign nationals have gotten life sentences or even the death penalty for drug running. What I’m saying is that Singapore are up front about it and it’s not enforced arbitrarily. Leaving your personal stash at home and abstaining for a few days should hopefully not be too difficult for the attendant engineers.
Wait, holy shit, it was legalized in 2022. Didn't know. Nice!
I frequently get the impression that the policymakers in Singapore are more progressive than they reveal, but are extremely cautious about loosening up because they don't want to antagonise certain voter groups (e.g. people of certain religious persuasions). It is quite telling that the law was repealed in its entirety only in 2023, one year before the former Prime Minister Lee Hsien Loong stepped down from his position.
So, enforcement was certainly attempted and people were certainly detained for periods of time and forced to defend against charges that were laid.
It's not readily clear how often charges under Section 377 (1860-) or Section 377A (1938-) were laid in Singapore prior to 2007 (or of the charges laid how many cases came to trial and how many convictions occurred).
