The impact of restricted community accessibility on needle and syringe sharing among drug users in Baise city: based on the event study method

When individuals practice injecting drugs, the important factor in needle and syringe sharing among TDU groups is the restricted access to clean needles and syringes from the community. The community commercial channel for needles and syringes should serve as a public health resource, addressing access to clean needles and syringes for individuals and reducing the frequency of needle and syringe sharing among community-active TDU groups. Public health policies aimed at preventing HIV epidemics in TDU populations should fully consider the accessibility of needles and syringes for the TDU groups in the community, thereby enhancing the effectiveness of public health measures.
