This study is a part of the operational research which includes mapping and size estimation of female drug users, which forms the first key step in developing targeted interventions for this highly vulnerable key population. The results of this mapping study will assist in understanding the drug using scenario among female populations, which will ultimately form a baseline for service provision, based on which service providing organizations will develop targeted interventions within a specific geographical setting. In addition to identification of geographical areas where these populations congregate, this study also provides valuable information on overall drug use situation in the targeted communities, economics of drug use, treatment history, criminal justice history, availability of treatment services and various religious and cultural barriers to accessing information and services among the target group.
