A meta-analysis of cohort studies [34] showed that both alcohol and drug use disorders are strongly associated with suicide. Heavy alcohol consumers had a five-fold higher risk of suicide than social drinkers. The National Comorbidity Survey (NCS), focusing on adolescents, found no causal relationships between alcohol drinking behavior in general and suicide attempts, but reported a significant association between alcohol-related disorders and suicide attempts [35]. An increase in suicidal thinking, but not attempts, with alcohol abuse was found in the NCS-R population, but the strength of the association between suicide and asthma condition in the subpopulation with asthma was weakened by alcohol abuse [36]. An Italian study, carried-out in the context of the European Study of the Epidemiology of Mental Health Disorders, a part of the WHO World Mental Health Survey Initiative, showed that suicidal thinking and planning are increased by having an alcohol-related disorder, but that this increase was not paralleled by an increase in suicide attempts [37]. Psychological autopsy studies have confirmed the association between alcohol use and suicide [38], despite lumping alcohol with other drugs due to sample size limitations [39]. In spite of their limited statistical power, psychological autopsy studies in different nations over different decades have consistently documented that mood and substance use disorders, particularly alcoholism, are the most prevalent disorders in suicides [40–43]. Methodologically different psychological autopsy follow-up and case-control studies [34,44,45] indicate that alcohol- and other drug-related disorders are risk factors for suicide [39,46–49].
