Declining but not dying 放緩不代表受控
Heroin addiction is the prototype of drug abuse. As both a public security and public health problem, heroin addiction poses a major challenge to national governments around the world. A significant proportion of HIV infection worldwide have been caused by needle sharing in heroin users. In Hong Kong, heroin addiction has been on the decline in the past decade. Prevalence data from Central Registry of Drug Abuse shows the decline in all districts from 1996 through 2000 to 2005. Almost all heroin users are male as shown by pie charts in each district. Despite the decline, some districts do show a persistently higher level compared to neigbouring areas. In the new towns, the decline is not as marked. The spatial heterogeneity of heroin addiction suggests that locally relevant intervention programmes would be needed to minimise harm caused to the society.
