Addiction, substance misuse and suicide risk

Substance misuse is the incorrect or harmful use of substances such as alcohol, illegal drugs, prescription and over the counter medications. 

The link between alcohol and substance misuse and suicide is complex. But research shows that alcohol and substance misuse can increase suicide risk and contribute to suicidal behaviours.

People at risk for suicide may struggle with both addiction and other risk factors at the same time. 

Using substances as a coping mechanism - substance misuse can be a sign of unresolved underlying issues. Some people use alcohol and substances as a form of self-medication to help cope with emotional and/or physical pain but unfortunately substance misuse can worsen, and trigger other symptoms. Longer term, it can increase suicidal thoughts and behaviours.

Affect on mental health - excessive use of substances can negatively affect a person’s daily life. It increases health risks and can lead to dependence and addiction changing a person’s mood, thinking and behaviour. Alcohol is known to have a depressive effect and there is a strong association between regular heavy drinking and suicidal thoughts, suicide attempts, and death from suicide.

Impaired judgement - substance misuse can negatively affect someone’s decision-making and judgment, leading them to act impulsively or make decisions they wouldn't otherwise make. Many substances can heighten impulsivity, making individuals more likely to act on suicidal thoughts without foreseeing the consequences.

Impulsivity - substance misuse can increase impulsivity, which can lead to suicide attempts.

Disinhibition - substances like alcohol can lower inhibitions, reducing the mental barriers that prevent someone from attempting suicide.

Affect on physical health - long-term substance misuse can lead to various physical health complications, including liver disease, cardiovascular problems, and neurological damage, which can worsen feelings of despair and hopelessness.

Stigma -  stigma associated with both substance misuse and mental health issues can prevent individuals from seeking help and accessing treatment. This can further isolate them and worsen their problems. 

Empathy and understanding can help us challenge stigma and create supportive environments that promote and encourage recovery.

It can be difficult to know what to do and it's not always easy and straight forward but some of the things you can do include:

  • Listen without judgement
  • Let them know you care
  • Remind them they’re not alone
  • Encourage them to get help
  • Encourage healthy coping mechanisms

If you have a substance misuse problem, or you know someone who does, support and advice is available.

Booking an appointment with the GP is a good place to start. There is also a wide range of helpful information and resources online that could help.
