There is some evidence to support the incremental utility of psychosocial interventions in combination with pharmacotherapy for OUD 274, 275. These interventions include contingency management (CM) and other cognitive-behavioral therapies (CBT), as well as supportive psychotherapy 276. In opioid-using adolescents and young adults, motivational enhancement therapy (MET) and CBT, as well as combined MET/CBT, have demonstrated efficaciousness in compared to a community reinforcement approach, although findings appeared to be mediated by sex and age 277. Other meta-analytic work conclude that structured psychosocial interventions contribute little to opiate substitution programs beyond the routine counseling provided with pharmacological treatment 278. 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. Alcohol use has been one factor that has been shown time and time again to increase the risk of suicidal behaviours.

• For example, being younger or having served time in the military does not mean that suicidal behaviour is inevitable.
• Furthermore, the data and clinical history are self-reported, as in most other studies on this issue.
• Notably, impulsive suicide attempts may be a strong indicator of relapse risk after discharge.
• Accumulating evidence suggests that kappa antagonism properties of buprenorphine may underlie its antisuicidal properties via reducing negative affect responses in the amygdala and enhancing activity of regulatory frontal regions.

Opioids

A state of intoxication may trigger self-inflicted injuries, not only by increasing impulsivity, but also by promoting depressive thoughts and feelings of hopelessness, while simultaneously removing inhibiting barriers to hurting oneself 177. Indirect mechanisms, including alcohol consumption as a form of self-medication for depression, or alcohol use as a marker for other high-risk behaviors, may also be relevant. Although we are far from understanding the relationships between alcohol use and suicidal behavior, a number of possible direct mechanisms for the association have been proposed. Taken together, these results remain highly suggestive, but not conclusive, for a neurobiological link between alcohol misuse and suicidal behavior. Alcohol influences brain chemistry and function, contributing to the emergence or intensification of suicidal thoughts. As a central nervous system depressant, alcohol slows brain activity, which can exacerbate existing feelings of the link between alcohol and suicide sadness or despair.

Signs and symptoms

Animal studies suggest that an activated kappa receptor system is a key mediator of dysphoria-related symptoms and depressive-like behavior 215–220, both relevant to mood disorders and chronic drug use/dependence 221–228. In humans, increased expression of kappa receptors has been found postmortem in the brains of suicide victims 229. Moreover, kappa receptors availability in the amygdala-anterior cingulate-striatal circuitry were shown to mediate the phenotypic expression of dysphoria 230.

• The studies addressing the association between AUD and suicide among drug abusers or among patients with mental disorders were excluded.
• People who abuse drugs or have an alcohol addiction are up to 14 times more likely to die by suicide than others.
• If you struggle with other mental health disorders, alcoholism can worsen depression and suicide ideation.
• Ultimately, clinicians like Stafford and Humphreys said they hope people who decide to drink alcohol do it consciously, armed with knowledge about its risks.
• Emerging research suggests that some individuals with particular types of substance use and abuse may be more likely to engage in suicidal behaviors.
• Receiver operating characteristic (ROC) analyses were used to identify patients who were at risk of having attempted suicide in the last 3 months.

Alcohol withdrawal

The U.S. surgeon general recently declared alcohol the third-leading preventable cause of cancer. Yet, despite increasing evidence linking alcohol consumption to the disease, little is known about the biological mechanisms behind the association. In the United States, the Diagnostic and Statistical Manual of Mental Disorders (DSM) is the most common diagnostic guide for substance use disorders, whereas most countries use the International Classification of Diseases (ICD) for diagnostic (and other) purposes.

Our 2023 report explores the relationship between alcohol and suicide for LGBTQ+ people in England in their own words.

We screened 8548 retrieved references and included 31 eligible studies in the meta-analysis involving 420,732 participants. Thus, the evidence was sufficient to make a robust conclusion regarding the objective of the study for estimating the association between AUD and suicide. The low incidence rate of suicidal behavior in most populations may make it impractical to study drinking immediately prior to suicidal behavior using intensive prospective study designs such as experience sampling where data may be gathered several times per day. Moreover, asking an individual to continue to document their drinking during an unfolding suicidal crisis raises ethical concerns and would presumably require the investigator to intervene whenever possible, altering the course of the phenomena under study.

Statistical analyses of psychological autopsies of suicide deaths provide evidence that AUD is a strong risk factor. Based on the available studies, it can be concluded that the probability of suicidal behavior is about three times higher in persons with AUD than in those without AUD. Even higher values were found based on cohort studies that looked at people with AUD undergoing treatment. This bias can be explained by the fact that this group of people exhibits more severe symptoms than the general population. We added 8 sessions of CBT (2 sessions a week for 4 weeks) for suicidal thoughts and behaviors to standard residential drug treatment.

Suicide is a major public health concern and a leading cause of death in the US. 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.

1. Suicide and Alcohol Abuse in Adolescents

Mood shifts are also indicators, ranging from extreme agitation, rage, or anxiety to a sudden, unexpected calmness after a period of distress. This sudden calmness might suggest a decision to end their life has been made. Any combination of these signs, especially when alcohol is involved, warrants immediate attention. Identifying the warning signs of suicidal thoughts, especially when alcohol is involved, is important for intervention. Verbal cues can include direct statements about wanting to die, feeling like a burden, or expressing a lack of purpose in life. There is so much concern about Canadians’ drinking that some policymakers are advocating for warning labels on alcohol bottles like those on cigarette packages.

The two manuals use similar but not identical nomenclature to classify alcohol problems. For practical reasons, these studies should be based in settings that frequently treat those with AUDs who may be experiencing suicidal thoughts, such as AUD treatment programs, emergency departments, inpatient psychiatry units, and detoxification units. There is a clear need to conduct randomized trials of interventions for those with AUDs who are experiencing suicidal ideation.

Another theory of suicide suggests the severity of depressive symptoms, such as a hopeless sense of not belonging, is directly proportional to the likelihood of a lethal suicide attempt. Due to the cross-sectional study design and the lack of a second survey of the same participants or a long-term follow-up, no data on changes in suicidal ideation in and beyond the initial treatment can be derived. Correlations between dependence, self-assessment of suicide risk and self-assessed probability of a future suicide attempt.

Despite significantly elevated suicide risk in individuals with AUD/OUD, there is a dearth of research on pharmacological and psychosocial interventions for co-occurring AUD/OUD and suicidal ideation and behavior. Based on the above-mentioned studies, it is evident that several data sets from international publications are available regarding the interrelationship between alcohol use disorder and an increased risk of suicidal behavior. There definitely are cultural and demographic differences for the regions covered by the above studies. Nevertheless, international studies show that people with AUD represent a high-risk group for suicidal behavior. Unfortunately, there are only a limited number of quantitative studies on SUD, suicidality, co-morbidity, and psycho-social factors available especially in German-speaking countries. A similar study 30 investigated the relationship between suicide attempts and remitted substance use disorder, evaluating comorbidity and psychosocial factors in 354 patients with SUD in remission who had made at least one suicide attempt.

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. 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. Lower concentrations of 5HIAA have also been found in alcoholic individuals compared to controls 69 and in impulsive violent offenders compared to premeditated offenders 70.

Further research in this area can contribute to the development of reliable instruments for risk assessment and treatment approaches for substance users with suicidal tendencies. The results of the current study may contribute to improving early detection of individuals at risk. In clinical practice, suicidality should be given greater attention in patients with SUD.
