“…A positive association was found between depressive symptoms and injection material sharing in PWID samples in India and Canada (Armstrong et al, 2013;Lemstra, Rogers, Thompson, Moraros, & Buckingham, 2011), but not among a sample of PWID in Massachusetts, United States (Lundgren, Amodeo, & Chassler, 2005) nor among street-based female injectors in the city of Danzhou, China (Gu et al, 2010).
