When pregnant/postpartum women need substance abuse treatment there are numerous issues unique to their situation that need to be addressed. This particular 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 typically requires programs 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 stays in treatment the better their chance of lasting sobriety. Many programs for pregnant/postpartum women run six to nine months on average.
