"The results showed elevated rates of alcohol dependence in women with PTSD. One in three of the women suffering from PTSD developed alcohol dependence, but it was not just women who developed PTSD after experiencing a traumatic event who were at higher risk for becoming alcohol dependent. Although these women had the highest rates of alcohol dependence, women who experienced trauma but did not develop PTSD had double the rates of alcohol dependence of women with no history of trauma: 14.8 percent to 7.3 percent."
