A literature review and meta-analyses of cannabis use and suicidality

Cannabis use disorder and suicide attempts in Iraq/Afghanistan-era veterans

“…A recent review and meta-analysis (Borges et al, 2016) on cannabis use and suicidal behavior (i.e., suicidal ideation and attempts) identified five studies examining the association between suicidal ideation and heavy cannabis use and six studies examining the association between suicide attempts and heavy cannabis use. Meta-analysis indicated that heavy cannabis use was likely to be associated with both suicidal ideation ( OR = 2.53, 95% CI: 1.00 – 6.39) and suicide attempts ( OR = 3.20, 95% CI: 1.72 – 5.94); however, the authors of this review noted the limited number of studies examined as well as several key issues to be addressed in future research, such as inclusion of more diverse samples, inclusion of patients with and without comorbid mental disorders, and use of clinical interviews to diagnose cannabis use disorders (CUD).…”

The relationship between anger control, suicide behavior and attention deficit hyperactivity disorder among outpatients with cannabis use

“…24 Nevertheless, in a metaanalysis, suicide behavior has been reported to be more frequent especially in chronic cannabis use. 25 Also in a case-control study, the rate of severe suicide attempt was found significantly higher in individuals with cannabis use than those who did not use cannabis. 26 This study also states that comorbide psychiatric disorders may be associated with the use of cannabis or may increase the risk of suicidal behavior itself.Finally, it is stated that cannabis may increase the risk of mental disorders (including suicide attempt).…”

Impact of the study of marijuana and suicide in Mexico

“…This study also highlighted the lack of epidemiological studies addressing acute marijuana use and suicidal behavior and the limitations of chronic consumption studies due to the variety of definitions of exposure that have been used, the number of suicide cases observed and the concentration of research in certain countries or geographic areas (Borges et al, 2016). In the specific case of the population in the metropolitan area of Mexico City, the analysis of the cohort of the Mental Health Survey on Mexican Adolescents made it possible to estimate, for the first time in a representative epidemiological study in Mexico, that the eight-year for suicidal ideation and intent, is higher among marijuana users than non-users, particularly among those who begin to use it before adolescence, and those who used larger amounts of the substance during the year prior to the baseline measurement (Borges, Benjet, Orozco, Medina-Mora & Menendez, 2017).…”

“…The World Health Organization has published a report on the health and social effects of recreational cannabis use (WHO, 2016). This publication included the results of a systematic review of the association between marijuana and suicide (Borges, Bagge & Orozco, 2016), a mental health issue that had rarely been addressed in previous publications, yet one of great importance due to the magnitude of the problem of suicide, especially in middle-income countries (WHO, 2014).…”
