When pregnant/postpartum women need drug or alcohol rehabilitation there are a number of factors 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 facilities that are both individualized and flexible in their recovery plan. Although the program duration may vary depending on the woman's specific needs it is recognized that the longer a person participates in treatment the better their chance of a successful recovery. Many programs for pregnant/postpartum women run six to nine months on average.
