However, mRNA for CRF1, but not CRF2 receptors, were found to be reduced in the frontal cortex of suicides, along with mRNA for the alpha1, alpha3, alpha4, and delta receptor subunits of the GABAA-benzodiazepine receptor cortex 167. It has to be mentioned, however, that CRF receptor numbers and affinity have been reported to be either reduced 168 or unchanged by different groups of investigators 169. There is so much concern about Canadians’ drinking that some policymakers are advocating for warning labels on alcohol bottles like those on cigarette packages. 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.
Interestingly, suicidal behavior has been found in a man with cerebellar agenesis 138. Reduced serotonin function has been identified in suicides and possibly in serious suicide attempters (see 139 for a review) and alcohol dependent patients 140. 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.
However, in a later study conducted in Canterbury, New Zealand, Conner et al. 63 failed to detect an effect of gender in mediating the association between alcohol dependence and serious suicide attempts. Methadone is a long-acting full opioid receptor agonist that has been long used for treatment of individuals with OUD 237. Although methadone treatment in persons with OUD and comorbid depression may lead to modest improvement in depressive symptoms, they often require antidepressant medications to produce meaningful reductions in depressed mood 237.
Data Availability Statement
The reference lists of all included studies were scanned and the authors of the identified studies were contacted for additional eligible studies. Participants were asked ‘Have you ever made an attempt to take your life, by taking an overdose of tablets or in some other way? ’, ‘Have you ever thought of taking your life, even though you would not actually do it? ’ and ‘Have you ever deliberately harmed yourself in any way but not with the intention of killing yourself? Those who answered positively to either of these questions were asked a follow-up question on when this had last occurred.
Data collection and analysis
- We included observational (cohort, case-control, and cross-sectional) studies addressing the association between AUD and suicide.
- We found evidence of a linear association between total AUDIT score and suicide attempt, suicidal thoughts and non-suicidal self-harm in a representative English general population sample.
- Alcohol prevention programs may positively impact public mental health and help reduce suicide risk indirectly.
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. Preuss et al. 87, in a large study involving 3190 individuals with alcohol dependence, demonstrated an association between suicide attempts and current situation of unemployment, separation or divorce and fewer years of education. The existence of a link between alcohol use and suicide was known to Kraepelin 6. This link has been advanced more convincingly since the mid-1960s 7–9 and confirmed in recent years 10–13.

Alcohol and depression
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•. In this review, we summarize literature on the role of AUD and opioid use disorder (OUD) in contributing toward the risk of suicidal thoughts and behavior and discuss treatment interventions. 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. In view of the strong link between alcoholism and suicide, there is a clear need to provide public health education regarding sensible drinking.
