Remember several years ago when there was some incident, and the chinese delegate said that they were also a country of law and order. However, they believed that with more order they needed less laws.
We have over a half million people in prisons for drug offenses. Coddling prisons, I guess.
China executes them in great numbers, yet judging from the numbers presented in the article - it sounds like they're fighting a losing battle as well.
Maybe if they (and us, of course) increase the executions ten fold or a hundred fold we can finally get people to restrict their consumption to government approved substances.
