San Diego Suicide Study. II. Substance abuse in young cases.
Fifty-three percent of 133 consecutive young suicides had a principal psychiatric diagnosis of substance abuse. Twenty-four percent had an additional principal diagnosis of atypical depression, atypical psychosis, or adjustment disorder with depression. The relationship of the substance abuse to the additional diagnosis was usually obscure, though this subgroup was similar to the group with only substance abuse on a number of factors. Typically, substance abuse was a chronic condition present for nine years. Multiple substance abuse was the norm in these cases, and marijuana, alcohol, and cocaine were the most frequently abused substances. Substance abusers without other principal diagnoses received psychiatric care less frequently than those with additional principal diagnoses.
