“…This is particularly important for marginalized PWID whose sole source of obtaining sterile needles and condoms is through government-funded harm reduction services. A limited body of evidence suggest that similar to several international settings (Van Boekel, Brouwers, Van Weeghel, & Garretsen, 2013), socio-cultural stigma (e.g., negative attitudes towards PWID and their families) within several communities across Iran creates barriers to accessing important health and harm reduction services and therefore prevent PWID from getting the help they need (Abedinia, Rasoolinajad, Noorbala, & Badie, 2019;Amin-Esmaeili et al, 2016;Deilamizade, Moghanibashi-Mansourieh, Mohammadian, & Puyan, 2019;Karamouzian, Akbari, Haghdoost, Setayesh, & Zolala, 2015;SeyedAlinaghi et al, 2013;Zolala, Mahdavian, Haghdoost, & Karamouzian, 2016). Furthermore, while Iran's drug policy has shifted from complete criminalization of substance use to a more evidence-based -yet heavily medicalized-approach in the past 40 years, PWID continue to face structural stigma and discrimination (e.g., facing ignorance and receiving substandard care) when seeking healthcare and harm reduction services (Karamouzian et al, 2015;Rahmati-Najarkolaei et al, 2010;Tavakoli et al, 2020).…”
