Prevalence of Suicide

In any given year, about 44,000 people will die of suicide, which amounts to approximately 121 suicides per day. The vast majority of people who die by suicide—at least 90%—are battling a psychiatric disorder. But a large number of people who die by suicide also might be using substances or alcohol. In fact, people who have alcohol or drug abuse disorders are 10 to 14 times more likely to die by suicide.

According to the Substance Abuse and Mental Health Services Administration (SAMHSA):

  • 22% of suicides involve alcohol inebriation
  • Opiates (prescription painkillers and heroin) are found in 20% of deaths involving suicide
  • Marijuana use is present in 10.2% of suicides
  • Cocaine use in a factor in 4.6% of suicides
  • Amphetamine usage is found in 3.4% of suicides

In addition to deaths, alcohol is a factor in suicide attempts, with 30% to 40% of suicide attempts involving alcohol intoxication. In addition, suicide attempts land about 650,000 people in emergency rooms in any given year.

How Alcohol and Drugs Increase Suicide Risk

There are several different ways that alcohol and drug use increases suicidal thoughts and behaviors. Research shows that substance abuse in and of itself can increase these risks, especially among those who engage in chronic substance use.

Some of the ways that substance use increases suicidal risk include:

  • Reductions in sound judgment and impulse control
  • Drugs and alcohol can disrupt neurotransmitter pathways, resulting in inhibition loss
  • Substance misuse can lead to neurological damage and serious medical complications, which can increase the risk of psychiatric diseases linked to suicide

Different substances may have varied effects on the body, and create unique suicide risks. Drugs can have stimulant effects, depressing effects, or a combination of both. For example:

  • Stimulants (cocaine, amphetamines) can lead to decreased inhibitions, erratic behavior, and impulsiveness, all of which increase the risk of suicidal behaviors
  • Depressants (alcohol, opiates) may be linked to the feelings of hopelessness and depression common among people with suicidal behaviors

Additionally, people who are contemplating suicide may believe that being under the influence of drugs or alcohol during a suicide attempt will decrease pain or make them more likely to follow through. Substance abuse also reduces the chance that a person will be able to use their cognitive skills to consider alternatives to suicide or to think clearly enough to reach out for mental health support.

Other Risk Factors for Suicide

Substance abuse alone can increase your risk of suicide. Still, in most cases, people who use substances and die by suicide experience co-morbid psychiatric conditions. In addition, age and other socioeconomic determinants may increase risk.

People who have psychiatric disorders along with substance use disorders are at a higher risk of suicide.

Here’s what to know:

  • People at highest risk are those with bipolar disorder and clinical depression
  • Schizophrenia and anxiety disorder also increases the risk
  • Males with both depression and alcoholism have the highest risk of suicide
  • People who have bipolar disorder and alcohol use disorder have a 21% to 42% increased risk of suicide attempts
  • People who have both bipolar disorder and substance use disorder have an increased risk of suicide attempts in comparison to people who experience bipolar disorder only

Certain individuals who have substance use issues may be at increased risk of suicide:

  • Young people with substance use issues are at higher risk of suicide
  • Among American and Alaskan native people, a combination of alcohol and depression is the most prevalent risk factor for suicide
  • Depression, social problems, and financial issues along with substance use issues increase suicide risk
  • People who are generally prone to impulsive behavior and who use drugs or alcohol are at an increased risk of suicide

Getting Help

When it comes to preventing suicide, a multi-factorial approach works best. Addressing psychiatric conditions, social conditions, and life circumstances, along with any substance use issues, is vital when it comes to decreasing the risk of suicide.

First, it’s important to understand and recognize the signs of suicide ideation, as well as substance use.

Some warning signs may include:

  • Increased use of drugs and alcohol
  • Isolating oneself from family and friends
  • Feeling detached, without hope, or numb
  • Noticeable changes in sleeping and eating
  • Intense mood wings
  • Uptick in risky and impulsive behaviors
  • Giving away or donating your personal items
  • Sharing thoughts of wanting to die, or wanting to be gone from life
  • Making active plans for dying by suicide

If these warning signs apply to you or someone you know, get help as soon as possible, particularly if the behavior is new or has increased recently. All too often, people who die by suicide have been showing warning signs, but they may not have been taken seriously. Therapy, psychiatric care, and medications can help address any psychiatric conditions that are contributing.

People who experience substance use or misuse may find substance use counseling helpful. Others may require in-patient care at a substance abuse treatment center. You can go to to find a substance abuse treatment center near you.

At other times, it may be important for you or your loved one to seek emergency care for suicide. If you or your loved one is at immediate risk of self-harm or suicide, there is effective and confidential care available to you.

A Word From Verywell
