It will NEVER have an effect. WADA is a BS flag waving nothing of an organization anyway.
Here is an interesting piece from the cia website:
CHINA major transshipment point for heroin produced in the Golden Triangle region of Southeast Asia; growing domestic consumption of synthetic drugs, and heroin from Southeast and Southwest Asia; source country for methamphetamine and heroin chemical precursors, despite new regulations on its large chemical industry; more people believed to be convicted and executed for drug offences than anywhere else in the world, according to NGOs (2008)
Heroin and METH! It reminds of our own stupid fight here in the U.S. with pot. PED's are the least of China's worries. In the end this means raws are going to get more expensive for kickbacks, payoffs and the like.
