Alcohol use and death by suicide: A meta-analysis of 33 studies
However, 5-HT3 receptors were not found to be altered postmortem in suicides [147]. Figure 1 indicates the impact of alcohol abuse and misuse on suicide risk and the importance of the detection and treatment of alcohol use disorders for suicide prevention. Therefore, suicide prevention should focus on the diagnosis and treatment of alcoholism [63] and other substance-related disorders.
Trends Over Time
Whether you’re seeking treatment for yourself or you’re concerned about a loved one, know that there are many ways to help prevent suicide and stop alcohol misuse. Many people in similar situations have benefited from a combination of mental health and substance use disorder treatment. Alcohol is the most often detected substance in the body of a person who has committed suicide. It may be used to reduce the last instinctive hestitations to taking one’s own life. People with cancer-related depression often use alcohol as a means of coping but they very rarely use it in order to kill themselves through acute intoxication.
- A study [52] assessed the association between AUD and suicide in two different countries (the USA and France) concurrently.
- From 2016–2017 to 2020–2021, the average annual number of U.S. deaths from excessive alcohol use increased by more than 40,000 (29%), from approximately 138,000 per year (2016–2017) to 178,000 per year (2020–2021).
- Research shows that teens and college-age young adults often engage in binge drinking and high-intensity drinking.
- In order to explore the sources of heterogeneity, we performed meta-regression analysis considering mean age, gender (percent of men), adjusted/unadjusted effect estimates, and a high/low risk of bias as covariates (Table 2).
- Suicide prevention is primary with respect to alcohol use, but must take into account the alcohol abuse especially in cases where the alcohol use facilitates suicide behavior.
Statistical Analysis
However, despite higher rates of impulsive attempts and a higher level of lethality in patients with alcohol use disorders, the use of alcohol at the time of attempt did not differ significantly between impulsive and non-impulsive attempters [113–115]. We each have unique tolerances, relationships, and reactions to alcohol. If you struggle with other mental health disorders, alcoholism can worsen depression and suicide ideation. If you’re with someone who might have drunk too much, call 911 right away.
More on Substance Abuse and Addiction
Knowledge about who is at risk of suicide is crucial, and a number of interventions show promising effects. Future research must focus on the development of suicide-prevention based on specific assessment and treatment protocols. Aharonovich et al. [258] found that all subtypes of depression increased the risk for making a suicide attempt in patients with substance dependence abuse. Major depression occurring before the patient became substance dependent predicted the severity of suicidal intent, while major depression during abstinence predicted the number of attempts. Using the psychological autopsy method, Heilä et al. [254] investigated schizophrenic subjects in whom active illness and depressive symptoms were highly prevalent immediately before suicide and a history of suicide attempts was common. Women were more likely to have committed suicide during an acute exacerbation of the illness.

This means that alcohol-related suicide is mainly a male phenomenon, as was shown in previous studies [96,97]. Follow-up studies suggest that alcoholics may be between 60 and 120 times more likely to complete suicide than those free from psychiatric illness [12]. Studies of samples of completed suicides indicate that alcoholics account for 20–40% of all suicides [99].
It is necessary to analyze suicide statistics in Poland very carefully [23]. A study conducted between 2007 and 2009 by Frost et al. [34] in Norway estimated that toxicological investigations were performed in 361 of 365 autopsies. The collected matrices, blood, and urine were analyzed by GC, LC–MS and revealed the presence of benzodiazepines, alcohol, opioids, and psychoactive drugs. Another study [36], conducted retrospectively on 588 autopsy cases related to suicides, revealed that 30.6% of the cases were of suicide by the intentional consumption of organophosphates and local plants, followed by other compounds in agricultural use. The mean age was about 25 years, with no particular gender difference. A positive history of suicide attempts was present in 14% of the cases; meanwhile, in 22% of the cases, there was a history alcohol intake.
Moreover, literature studies are often not homogeneous, leading to inconsistent and non-representative socio-demographic and public health analyses of such phenomena. Socio-cultural background and legislation influence rates and methods of suicide. effects of ayahuasca on mental health and quality of life in naïve users Therefore, significant differences can be observed between countries [6,11]. Intentional self-poisoning is one of the most frequently used methods of committing suicide, along with using firearms and committing suicide by hanging [12].
Alcohol misuse is an important risk factor for suicide in elderly people [208]. Psychiatric disorders, especially depression, are common in suicides in Western [208], as well as in Eastern countries [209]. Depression on the other hand, is frequently comorbid with alcohol abuse/dependence in the aged [210–212].
They have contradictory affective reactions and are often confused as to whether others love or hate them and whether they love or hate others. They have difficulty in distinguishing between the good and evil impulses in themselves and other people. Copello et al. [220], after reviewing the literature, concluded that people with drug and alcohol use disorders often behave in ways destructive to family life and relatives. Translated, this mean that one out of four youths regularly engages in binges and that about the same proportion has started taking alcohol early in their life when their brain is still maturating. Among people with depression, those who consumed substances or alcohol have a higher probability of attempting suicide as compared with depressed individuals who did not [201]. The existence of a link between alcohol use and suicide was known to Kraepelin [6].

The aim of this publication was to juxtapose the data from two sources to compare the discrepancies between them. To date, there have been few articles addressing suicide poisoning, and not a single paper has been written that analyzes suicide poisoning statistics over the past 21 years with two data sources. Additionally, in the case of suicide poisoning, knowing what substances are used in suicide attempts may be helpful in limiting access to these substances. Suicidal behavior (suicide method in particular) varies across countries. In other countries, hydrogen sulfide and helium are used for suicide purposes (e.g., Japan) [4]. Research on suicide methods is still inadequate, especially in some geographic areas.
We can have high confidence based on the current evidence that AUD increases the risk of suicide. Therefore, further research is very unlikely to change our confidence in the estimate of effect. This finding supports the alcohol cessation programs to reduce alcohol use among the general population. However, there is insufficient evidence in regard to the dose-response relationship between alcohol drinking and risk of suicide. Further investigation based on observational studies are needed to expect the dose-response pattern of alcohol-related suicide. Measures of alcohol effect were expressed as risk ratio (RR) and odds ratio (OR).
We did not examine other factors (e.g., alcohol use disorders, availability of alcohol) that might also influence associations between acute alcohol use and method of suicide. About 28% of decedents were not tested for alcohol, with the potential to bias results. The amount of time from the act of suicide to death was not routinely available in NVDRS. Such time might affect BAC results because death generally takes minutes with firearms and hanging, but can take several hours in self-poisonings, providing more time for alcohol metabolism in this group. Data on access to medical care was also not available in NVDRS, another factor that might affect time to death.
A study [52] assessed the association between AUD and suicide in two different countries (the USA and France) concurrently. Thus, this study is presented twice in Table 1 as well as the forest plots. Eight studies teen drug abuse reported the association between AUD and suicidal ideation, 15 studies reported the association between AUD and suicide attempt, and 14 studies reported the association between AUD and completed suicide.
A further 7.3% of suicides were estimated to be among people in their second year after release from jail. These findings simultaneously highlight the extraordinary concentration of disease burden, including suicide deaths, among people who have experienced incarceration, and the need for greater investment in improving the health of this population. Because suicide is a complex problem, no single approach is likely to contribute to a significant, substantial decline in suicide rates. Clinical studies of suicide prevention are hindered by methodological and ethical problems, especially since many people at risk do not have contact with clinical services.
