Since 2001, the Women's Health CoOp (WHC; PI Wechsberg; RO1s DA011609S; AA014488; HD058320) has successfully adapted an evidence-based intervention to reduce sex- and drug-risk behaviors in drug-using South African women. However, with a rapid rise in meth use, the Western Cape is experiencing a new drug epidemic. A previous WHC study data indicated that the WHC had limited success in reducing the use of this among women. Alarmingly, among WHC participants, a greater proportion of pregnant than non-pregnant women reported using meth (n=24/26=92%; n=238/356=67%; p=.01). These findings are underscored by a lack of a focused and intensive treatment for meth-using pregnant women who live in impoverished townships. Thus, this project responded to PA-09-021 International Research Collaboration on Drug Abuse and Addiction Research (R21) by developing treatment options for meth use among pregnant women and using the long collaboration between WHC staff and local treatment providers to develop our first project to treat meth use in pregnant women.
