Actually...my friend went to an organized rave in north Beijing, the authorities stopped the bus on the way back to the city, all Chinese were drug tested, the foreigners were just ignored for some reason.

I'm not saying that it doesn't happen, but I've never heard of anyone getting even deported for drugs, let alone jailed. But remember Chinese laws are enforced selectively, so it is playing with fire.
