Social networks, secondary syringe exchange, and opioid agonist therapy retention among people who inject drugs in Hartford, CT
Background: Opioid agonist therapies (OAT) and harm reduction such as syringe service programs (SSP) have been shown to be effective in preventing adverse outcomes such as overdose deaths, HIV and Hepatitis C in-fections among people who inject drugs (PWID). The importance of social network influenc...
