Suicidal Thoughts and Alcohol: A Deadly Combination

In much of the world, alcohol is a regular and accepted part of celebrations, sporting events, and meals. Often, we think of alcohol as a normal part of life. However, drinking alcohol is extremely dangerous for anyone experiencing suicidal thoughts. Substance use is strongly correlated with suicidal behaviors, especially among adolescents.[1] Alcohol can cause shifts in mood, ranging from euphoria to hopelessness. Alcohol also lowers inhibitions and may increase impulsivity, which makes it especially lethal since a person who is intoxicated may be more likely to act on impulses (such as attempting suicide) than a person who is sober.

In fact, at least half of all suicides are accompanied by alcohol use.[2] One study estimated that every drink consumed increases risk of suicide attempt by 30% and found that up to 35% of all suicide attempts are attributable to acute alcohol use.[3] This means that if a person is feeling distressed, having just one drink makes them nearly three times more likely to attempt suicide. Clearly, alcohol and suicidal thoughts don’t mix well.

This is especially concerning because many young adults experience depression, anxiety, and/or suicidal thoughts just at the time when they are likely to begin using alcohol. 29% of high school students[4] and 39% of college students[5] reported symptoms of depression within the past year. Meanwhile, approximately 60% of high school students4 and 77% of college students5 report that they have used alcohol in their lifetimes. Where these groups overlap can be deadly.

So what can we do? There are very good reasons to limit one’s alcohol intake and regularly pay attention to whether you or a friend is exhibiting problematic drinking behaviors. People with substance abuse disorders are much more likely to attempt suicide than those who do not suffer from addiction.[6] Also, when you act as a gatekeeper and look for warning signs of distress or suicidal thoughts, keep drinking in mind as well. Sudden changes in substance use or ongoing substance abuse are warning signs of suicide. People with substance use disorders may use substances to cope with underlying mental health issues, or they may develop mental health issues from their use of substances. Professionals can help treat patients with dual diagnoses of mental health and substance abuse concerns.

If you know someone who is intoxicated and seems depressed or starts talking about suicide or exhibiting warning signs while drinking, take them seriously. Even if you don’t believe this person would feel suicidal while sober, they are at high risk while intoxicated. A distressed, intoxicated person should be treated like a distressed sober person—ask them direct questions, stay by their side, and seek professional help—while keeping yourself safe in the process.

If you see that a person is exhibiting warning signs of suicide, try to help them avoid alcohol while they seek professional help. Adding drinking—even moderate social drinking—to other warning signs of suicide can be lethal. And most importantly, never offer alcohol or suggest going out for drinks as a way to help someone who is in crisis. Drinking is not only a negative coping mechanism that can exacerbate depression and other mental health problems, but it can increase impulsivity and make the person more likely to act on suicidal thoughts.
