The answer, as this guy found out, is a resounding "Oh, hells no!"
Singapore outlaws the sale of chewing gum and has strict fines for littering and a mandatory death sentence for drug peddling. The crime rate on the sparklingly clean island nation of 5 million people is among the lowest in the world.
(The chewing gum ban, if I recall correctly, was put in place because they didn't want people dropping their gum on sidewalks. A country that bans gum outright is not likely to put up with any of your shenanigans.)
