Guangdong is the top target in China's nationwide drug crackdown
Province is mainland's biggest market for illicit narcotics and has largest population of addicts

Guangdong's booming illicit drug trade and large population of addicts have made it a top target in a new nationwide police crackdown.
Guangdong and Shandong provinces each have 10 cities among the 108 covered by the crackdown from the Ministry of Public Security, the People's Daily online news portal reported yesterday, citing assistant minister Liu Yuejing.
The southern province is the mainland's biggest market for illicit drugs and has developed a clan-based industry for the manufacture of synthetic narcotics, especially Ice, or methamphetamine, some experts say.
It also has the biggest population of addicts, with about 457,000 people on a register of suspected users, according to the provincial public security department.
The total has been growing by about 40,000 people a year since 2009, the China News Service reported.
Li Xiaodong , executive member of the board of the China Association of Drug Abuse Prevention and Treatment, said one of the big issues was migrants from other parts of the country.
