Seriously, yeah, irrational cultures should be entered into lightly and only when absolutely necessary. If someone with "authority" decides to target you for whatever reason, you may find that your life becomes permanently destroyed. Not to say there aren't tons of steroid users there, especially national athletes (the joke about the womens swim team is based on truth), but if someone decides to fuck with you...shudder...it could get very, very ugly.
Funny, but I recall an article from a few years back, talking about pot-tourism in China. It described a circuit that outsiders would take, mostly through rural areas, where you could buy ounces of strong indica for $5 - $20, and basically stay cooked for the entire journey. I suppose the leniency in this case is due to the fact that these areas are making good money from tourism that they wouldn't otherwise have a chance in hell of getting. But holy shit, I personally wouldn't even want to LOOK at pot or any other drug if I were in such an irrational, corrupt society.
