Alcohol, suicide and self-harm
There is a strong link between alcohol, suicide and self-harm.¹,²
Alcohol is a risk factor for suicide
Usually a number of factors together increase a person’s risk of suicidal behaviour. These include mental health problems, social isolation, drug use, traumatic life events and family history of suicide. Alcohol is an important risk factor.3 In Ireland, alcohol is a factor in:
- More than half of all completed suicides4
- Over 1 in every 3 cases of deliberate self-harm5
Hospital emergency departments see far more cases of self-harm on days when people are likely to have been drinking, such as after public holidays and weekends.6
The World Health Organisation (WHO) has estimated that the risk of suicide when a person is currently abusing alcohol is 8 times greater than if they were not abusing alcohol.
Alcohol is a risk factor we can influence. For people at risk of self-harm and suicide, it is important to recognise how alcohol can increase the risk and keep within the low-risk drinking guidelines.
Men are particularly at risk of suicide, and our youth suicide rate is high
- Overall, the male suicide rate is approximately four times the female rate.7
- Suicide is the leading cause of death among young Irish men aged 15 to 24.
A study of suicide in Ireland revealed that alcohol was more likely to be found in the younger age group at autopsy and up to 16% also had some type of drugs detected in their system - the ratio of males to females was five to one.8
The drinking and binge drinking culture in Ireland, which is especially strong among young people, is a factor in this.
It has been estimated that reducing Irish adolescents’ heavy drinking should reduce their rate of deliberate self-harm by at least 17%.9
