Serotonin depletion was also found in individuals displaying aggressive and impulsive behavior [139] and was a predictor of both early-onset al.cohol use disorders [141] and suicide attempts among alcoholics [142,143]. Ethanol has been shown to potentiate acutely 5-HT3 receptor function and to modulate chronically 5-HT3-augmented mesolimbic dopaminergic function, but also to regulate alcohol drinking and its reinforcing properties at the ventral tegmental area level [145,146]. The diagnosis of depression is crucial for suicide prevention because treatment of unipolar depression is different from that of bipolar depression, the latter increasing the likelihood of suicide if treated only with antidepressant drugs [228–232]. Incomplete symptomatology, impulsive actions, periodic alcohol abuse, compulsive buying behaviors, acute delusional episodes, medicolegal actions and comorbidities can hide or modify bipolar symptomatology.
In fact, we are so concerned about excessive drinking that we implement initiatives like Dry January where we challenge ourselves not to drink alcohol for a month. Suicide hotlines are designed to assist people contemplating suicide or otherwise in distress by providing emotional support and connecting them with crisis resources. The following resources offer confidential services, so you don’t have to provide any identifying information if you don’t want to. They may think they’re a burden to others and begin to develop a higher pain tolerance and fear of suicide.
- Alcohol abuse is a means of easing one’s psychological stress but, at the same time, impacts on all other factors, rendering suicide more likely.
- In fact, we found that alcohol use increased the risk of death by suicide by a frightening 94 per cent.
- However, such studies do not account for the utility of psychosocial treatment in reducing suicidal ideation and behavior in individuals with OUD, and research on psychosocial interventions for opioid use and co-occurring suicidality remains an outstanding area of study.
- Additionally, chronic opioid use can result in neurobiological changes that lead to increases in negative affective states, jointly contributing to suicide risk and continued opioid use.
Importantly, serotonergic dysfunction may be central to the pathogenesis of depression [66], specifically with regard to 5-HT 1A and 5-HT 1B receptors [67] thought to play a role in mood and reward sensitivity, and regulation of impulsivity and aggression [67]. Thus, serotonergic dysfunction may reflect a common pathway to suicidal outcomes and AUD, perhaps mediated by underlying depression or impulsive aggression. Studies of serotonin metabolites support this; for example, in high- and low-lethality attempters, trait aggression is related to lower concentrations of CSF 5hydroxyindolacetic acid (5HIAA; a major metabolite of serotonin), and high lethality attempters demonstrated lower CSF 5-HIAA [68].
Although the use of alcohol for the purpose of facilitating suicidal behavior has rarely been examined, a large case series estimated that approximately one quarter of suicide attempters with AUA fit this pattern,22 suggesting it is common. Suicide deaths involving heavy alcohol use have increased significantly among women in recent years, according to a new study supported by the National Institute on Alcohol Abuse and Alcoholism (NIAAA). Previous research has shown that alcohol is a risk factor for suicidal behavior and that women have a higher risk than men do for suicide while intoxicated. And in the two decades leading up to 2018, suicide death rates in the United States increased, with the rate among women increasing faster than the rate among men. Methadone is a long-acting full opioid receptor agonist that has been long used for treatment of individuals with OUD [237].
Models of Suicide—Alcohol Relationships and Shared Risk Factors
Their anger is directed to the lost person significantly more than that of spouses whose suicidal partner had no alcohol problems [225]. Alcoholism in any close relationship causes tension and conflicts alcohol use disorder and depressive disorders alcohol research and complicates bereavement. Regarding the noradrenergic system, alcoholics had less alpha2 and beta1 adrenergic binding but more alpha1 adrenergic binding in the ventrolateral and orbital cortex [160].
A meaningful understanding of the different roles that alcohol and opioid use can play in suicidal behavior, however, will require continued study of their shared risk factors, mechanisms, and interventions. For example, further empirical research is necessary to differentiate the acute effects of alcohol and opioid intake on suicidality, separably from chronic or dependent use. Additionally, the gaps in intervention research on co-occurring suicidality and AUD/OUD are substantial, and pharmacological studies do not frequently account for the effects on suicidality, specifically, in addition to mood improvements in mood, in alcohol/opioid users. Given the high prevalence of alcohol/opioid use alongside escalating rates of suicide, there is a compelling need for attention to their cooccurrence. Alcohol and opioid use disorders (AUD/OUD) significantly increase risk for suicidal ideation, attempts, and death, and are the two most frequently implicated substances in suicide risk. We provide a brief overview of shared risk factors and pathways in the pathogenesis of AUD/OUD and suicidal thoughts and behaviors.

Suicide rates rose by 35% in the US over the past two decades [1] despite significant efforts to reverse this pattern by identifying risk factors and preventative interventions [2]. While mood disorders are among the most important risk factors for suicide [3–5], comorbidity with alcohol and substance use disorders (AUD/SUD) vastly increases vulnerability to suicidal ideation [6, 7], attempts [8, 9], and deaths [5, 10, 11]. Additionally, suicidal ideation and behavior are significant clinical concerns among those seeking treatment for AUD/SUD [12], and risk for highly lethal suicide attempts remains to be elevated even after remission from SUD [13]. While all substances elevate the risk for suicidal behavior, alcohol and opioids are the most common substances identified in suicide decedents (22% and 20%, respectively), far above rates of marijuana (10.2%), cocaine (4.6%), and amphetamines (3.4%) [14•].
Alcohol becomes a way of facilitating communication with others and adapting to the environment. Suicide is also both a social and a personal act and is related to conditions that render life difficult. It is possible that when one decides to commit suicide, he/she may select one of the options available to make the act more socially and personally acceptable, and one of these may be alcohol. The results of research do not support the hypothesis that, when a youth gets drunk, this in itself leads to that youth deciding to commit suicide. Altered glutamatergic receptors in the brains of people who died from suicide comprise reduced NMDA receptors [170] and increased caudate metabotropic receptors [171].
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. 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. Wojnar et al. [112] investigated the correlates of impulsive and non-impulsive suicide attempts in 154 hospitalized patients with alcohol dependence.
How Alcohol Use Affects the Risk of Death by Suicide
Bereavement counsellors should be alert for complex grief and mourning responses among this group of suicide survivors. Additionally, cognitive constriction (narrowed attention which reduces perceived potential solutions to a dichotomy—finding an immediate solution or committing suicide) is frequently observed prior to a suicide attempt [178]. Alcohol produces cognitive constriction through alcohol myopia [179], and this process has been confirmed by research showing that inhibition conflict (weighing pros and cons and identifying alternative solutions) mediates the relation between intoxication and social behavior [180].
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]. Several reports13–15 have examined risk factors for suicide attempts and suicide among individuals with AUD. Individuals with AUD share a number of neurobiological characteristics with suicidal individuals. Evidence of impaired serotonin (5-hydroxytryptamine; 5-HT) transmission has been found postmortem in the brains of suicide decedents [62], as well as in the cerebrospinal fluid (CSF) of nonfatal attempters [63, 64]. Reductions in binding of 5-HT1A receptors and serotonin transporter have likewise been found in prefrontal brain regions of alcoholic individuals [65].
These findings are interesting in pointing to alcohol-suicide commonalities in neurochemical alterations but, unfortunately, these post-mortem findings in the brains of suicides are only partially matched by alterations found in brains of non-suicidal people with chronic alcoholism. Notably, GABAA receptors were reduced [172–174], but the subunit compositions only partly overlap with those found in suicides. We hypothesize that use of alcohol alcohol and anxiety among individuals intending to make a suicide attempt, for the purpose of facilitating the suicidal act, may represent a distinct group typified by greater suicide planning, intent, lethality, and potentially co-occurring depression. Such an idea could be tested using a large sample of suicide attempts preceded by AUA whose motivations for alcohol use (among other variables) were retrospectively assessed shortly after the attempt.

Alcohol is the most often detected substance in the body of a person who has committed suicide. 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. However, a case of a cancer patient who committed suicide consuming two bottles of spirit was recently adhd and alcohol investigated and the conclusions are presented. The post-mortem cardiac blood and vitreous humor alcohol level was found to be 9.0 and 6.2 mg/ml respectively. Bartels et al. [255] reported that alcohol use was also correlated with depression and suicidal behavior, and depression alone accounted for over 80% of the explained variance in suicidal behavior.
