Peer power: can friends help stop HIV in injection drug users?
NCT ID NCT06103370
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aims to see if training people who inject drugs to become peer educators can help their friends get tested for HIV and use prevention tools like PrEP and treatment for opioid use. About 360 participants from syringe service programs in Maryland will be recruited, along with people in their social networks. Half of the groups will receive peer-educator training, while the other half will get equal attention on overdose prevention, and researchers will compare HIV testing rates and service use over 9 months.
