When pregnant/postpartum women need drug treatment there are a number of issues unique to their situation that must 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 programs that are both individualized and flexible in their treatment plan. While the length of stay 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 a successful recovery. Many rehab facilities for pregnant/postpartum women run six to nine months on average.
