1) Alcohol consumption is strongly associated with suicide and self-harm, especially among males. Higher national alcohol consumption from 1970-2000 correlated with increased suicide rates in Ireland. 2) Studies found that over half of young suicide victims in parts of Ireland were very drunk at the time of death, with blood alcohol levels over 160mg%. Alcohol use was also implicated in 40% of hanging deaths in another region of Ireland. 3) Acute intoxication, a history of heavy drinking, and alcohol dependence can all increase risk of suicide and self-harm by enhancing impulsivity, impairing problem-solving, causing emotional instability, and leading to adverse social consequences like relationship and job loss.
