DRUG-TAKING is spreading through Guangdong, leaving school students addicted in its wake, Governor Zhu Senlin has warned. In an address to start the province's latest three-month anti-drug campaign, Mr Zhu said international drug syndicates had formed underground networks in Guangdong to smuggle and trade drugs. Drug trafficking and drug-taking was spreading along the coastal regions from port cities and the Pearl River Delta area, the Governor said. A small number of primary and secondary school students, as well as young women had become addicts, he said. The Guangdong authorities would send 11 taskforces to various cities to help promote the anti-drug campaign, the Hong Kong-based Wen Wei Po said. Separately, Guangzhou police arrested 212 suspected drug traffickers and seized more than 200 grams of narcotics in a raid on the first day of the campaign. More than 150 public security officers of Baiyun district in the provincial capital raided five hotels, where most of the guests were from other provinces, in the early hours of Wednesday. A total of 190 grams of heroin and 45 grams of marijuana were seized. Police in various parts of Guangdong also arrested 5,000 suspected drug traffickers and addicts prior to the campaign. Since last month, security officials have unearthed a number of serious drug cases in areas including Shenzhen, Guangzhou, Zhuhai, Huizhou, Chaozhou, Jieyang, Foshan and Jiangmen. Guangzhou police uncovered the biggest drug case in the province late last month when they seized 18.96 kilograms of heroin and 700,000 yuan (about HK$642,000) in cash. Earlier this month, Shenzhen police arrested three alleged drug traffickers from outside the mainland.
