3 Asian nations warn citizens not to use marijuana in Canada

Marijuana may be legal now in Canada but at least three Asian governments are warning their citizens to avoid it, including the specter of possible arrest for Japanese and South Koreans.

China, the latest to weigh in, didn't go that far. Its consulate in Toronto issued a statement dated Friday reminding Chinese in its jurisdiction and students in particular "to avoid contact with and use of marijuana for the sake of ensuring your own physical and mental health."
