then again in Thailand if you have any stronger drugs than weed you wont have good time there. Even weed is strictly regulated.

Most asian countries have very strict rules against drugs. Hence you wont see em so much in open like you will see in EU/US for example. You wont be seeing much drug addicts strolling around in parks and so on. Now even in Japan you will see less and less as they recently caught all Yakuzas(basically whole yakuza exterminated). though this might lead to small criminals trying to take up their place.

Its harsh but works. Most likely only in asia just because they can enforce stuff like that easily.

In Eu for example people got so much rights that its almost impossible to enforce stuff like that. I mean in most EU countries you actually get yourself punished if someone breaks in and tries to rob you at your home and you just defend yourself and hurt the burglar.

Criminals also have tons of rights and it kind of breaks the system. Nobody cares if they get caught.
