Previous studies have found that marketing HRPs in correctional institutions requires a culturally sensitive approach to increase the incentives for participation. surveyed 2,239 new inmates in jails; they found that 694 were IDUs. Among those IDUs, 67 were PLHIV. In total, 56.6% of the IDUs had heard of harm reduction, but only 8% of the PLHIV had ever participated in a syringe-needle exchange programme. More than 51% had left their used needles in trash cans or gutters.
