Although several risk factors for suicidal ideation (SI) have been identified in the research literature, there is a pressing need for studies evaluating markers of risk differentiating ideators from people who have attempted. According to the interpersonal theory of suicide, habituation to painful or provocative experiences increases one's acquired capability for suicide, a necessary component for the transition from SI to attempts. This theory further posits that the acquired capability for suicide should be unrelated to risk for SI. This study tested this theory by examining injection drug use, relative to less painful means of drug use, in relation to SI, suicide plans, and suicide attempts.
