This meta-analysis revealed that AUD was significantly associated with an increased risk of suicidal ideation, suicide attempt, and completed suicide. Alcohol and psychiatric disorder have a complicated relationship. Alcohol drinking can have negative effects on mental health, causing psychiatric disorders and increasing the risk of suicide [54]. Countries that have higher rates of alcohol use generally also have higher rates of suicide [55]. Furthermore, current evidence indicates an association between alcohol dependence and impulsive suicide attempts [56,57]. In addition, there is a close link between alcohol abuse and depression and it is often difficult to determine which of the two is the main leading condition [58]. Pompili et al have suggested that people with alcohol disorder should be screened for suicidality as well as psychiatric disorders [59].
