When pregnant/postpartum women need drug rehabilitation there are numerous factors 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 often requires facilities that are both individualized and flexible in their recovery plan. While the length of stay 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 a successful recovery. Many programs for pregnant/postpartum women run six to nine months on average.
