【明報專訊】NEW trends of substance abuse in Hong Kong have emerged. In mid-April, Hong Kong police seized about HK$100 million worth of cannabis buds (大麻花), the biggest chunk ever detected in Hong Kong. It is believed that the legalisation of cannabis (大麻) in Canada has made drug trafficking easier. Moreover, the number of cannabis users under the age of 21 increased 48% year on year.
