Abstract
Evidence documents elevated rates of various types of drug use among people with posttraumatic stress disorder (PTSD). However, relatively little research has specifically examined crystal methamphetamine (CM) use among individuals with PTSD. The present study examined the relation between PTSD diagnostic status, PTSD symptom severity within symptom type clusters, and CM use histories among traumatic event-exposed individuals with versus without PTSD. Consistent with expectations, individuals with PTSD were significantly more likely to report CM use than trauma-exposed individuals without PTSD. Additionally, CM users with PTSD reported a longer duration of CM use than trauma-exposed CM users without PTSD. Finally, PTSD avoidance and hyperarousal symptoms, but not re-experiencing, were related to CM use. The potential clinical and research implications of the findings are discussed.
