Thailand is very strict when it comes to things these days and tourists trying to get their hands on various meds and drugs, wouldn't bother. Ending up in a Thai prison sounds like a nightmare.
Bangkok, Oriental setting
And the city don't know what the city is getting
The crème de la crème of the chess world
In a show with everything but Yul Brynner
....Had to sorry. One Night in Bangkok by Murray Head, for anyone wondering the reference.
