When pregnant/postpartum women need drug treatment there are several factors unique to their situation that should be addressed. This distinct group of addicted persons faces not only the personal shame of their addiction but also the reality of what their unhealthy choices may have caused their children. Substance abuse rehabilitation for pregnant/postpartum women often requires facilities that are both individualized and flexible in their treatment plan. Although the program duration may vary depending on the woman's particular needs it is understood that the longer a person participates in treatment the better their chance of lasting sobriety. Many rehab facilities for pregnant/postpartum women run six to nine months on average.
