Researchers at Western Psychiatric Institute & Clinic found that the proportion of alcohol-related suicides (1968-83) increased 3 1/2-fold. Successful suicide intervention programs must include data about substance abuse prevention. 5 stages of progressive drug use are described: experimental, social/recreational, circumstantial/situational, intensified, & compulsive. Alcohol subdues emotional pain, but may disinhibit suicidal behavior. Suicide by firearm & alcohol are linked.
