“…Widely implemented tobacco cessation programs have had a rapid population benefit (Land et al, 2010), and recent calls for smoking cessation treatment among HIV-positive individuals (Hoffman, Starks, & Gritz, 2009;Nahvi & Cooperman, 2009;Niaura, et al, 2000;Reynolds, 2009) support the need for upstream smoking interventions tailored to those at greatest risk of contracting HIV. Research also indicates that the concurrent treatment of drug co-dependencies is more effective in reducing relapse (Hurt & Patten, 2003;Reynolds, 2009). This is borne out in longitudinal studies of drug-using behavior in Baltimore IDU which showed that current cigarette smoking was negatively associated with cessation of injection drug use (Galai, Safaeian, Vlahov, Bolotin, & Celentano, 2003) and abstinence from smoking and alcohol reduced time to cessation of injection drug use (Shah, Galai, Celentano, Vlahov, & Strathdee, 2006).…”
