A majority of the 63 methadone users recruited were residing in the same district of which spent not more than 15 minutes for traveling. Walking was the commonest transport mode followed by cycling . There was no distance decay effect on traveling time but an association between distance and transport selection could be demonstrated. The residence locations displayed a compact distribution merging with the general population without any evidence of clustering. Though the distribution of methadone users could have been shaped by the location of clinic it can also be concluded that methadone clinics at convenient locations are needed if maintenance is a key determinant of service effectiveness. Findings Methadone utilization studies have so far been largely conducted on individuals with a cross-sectional approach 1 using national database 2 or through street interviews 3 4 . Apparently there are knowledge gaps in methadone users transport selection association of residence location with distance from clinic and possible spatial matching between users and the general population. This study aims at determining the spatial pattern of and the spatial influence on methadone treatment utilization in Hong Kong. Located in South Eastern China Hong Kong has a population of about 7 million a majority of which Chinese. There are 20 methadone clinics distributing over 16 out of 18 administrative districts figure 1 serving more than 95 of heroin users in the territory 5 . Methadone clients were approached by .
