Smoking marijuana is illegal in China
Marijuana is illegal in China, and so is any related action. Cannabis is quite a big industry in China.
Although there have been some recent laws brought up to protect the city from its drug slingers, the world of a pot smoker is quite relaxed and relatively “legal” in the city of Beijing. Foreigners have usually left well alone, again, unless they do something stupid. In some foreign countries, marijuana does not belong to drugs, but marijuana belongs to drugs in China.
