When pregnant/postpartum women need drug rehabilitation there are numerous factors unique to their situation that should 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. Although the length of stay may vary depending on the woman's particular needs it is recognized 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.
