“…Detox clients were 3.7 times more likely than MM clients to engage in high-risk sexual behavior (95% CI 1.6-8.1, P = 0.002), an effect that remained constant even when controlling for the younger mean age of Detox clients. This may reflect the role of the Detox as a substance abuse treatment entry point, in which clients are actively using drugs or alcohol and therefore are more likely to be engaging in risky sexual behavior (Ross et al, 1999;Aktan et al, 2001;Bagnall et al, 1990;Ericksen and Trocki, 1992;Fitterling et al, 1993;Flom et al, 2001;Morrill et al, 2001;Purcell et al, 2001;Scheidt and Windle, 1995;Somlai et al, 2000;Zenilman et al, 1994). It also may reflect the lower motivation to enter meaningful treatment, and thus reflect repeated and long-standing patterns of risky behavior associated with chronic drug use.…”
