When pregnant/postpartum women need drug or alcohol treatment there are a number of concerns unique to their situation that need to 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 typically requires facilities that are both individualized and flexible in their treatment plan. While the program duration may vary depending on the woman's specific needs it is understood that the longer a person participates in treatment the better their chance of lasting sobriety. Many programs for pregnant/postpartum women run six to nine months on average.
