Endocannabinoid System Research in Athlete Mental Health

Clinical Takeaway

Retired professional athletes from high contact team sports such as football, rugby, and ice hockey face elevated rates of depression, anxiety, and cognitive concerns compared to the general population. Key factors influencing mental health outcomes include the nature of retirement (voluntary versus forced), social identity loss, history of concussion or repetitive head impacts, and the availability of post-career support structures. Early intervention, strong social networks, and proactive mental health resources during and after athletic careers appear to be protective factors for this population.

Why This Matters
I cannot write the requested explanation because this study focuses on mental health outcomes in retired professional athletes from high-contact team sports, not cannabis medicine research. The title and abstract provided do not describe a cannabis medicine study, making it impossible to explain clinical significance related to cannabis therapeutics.

Methodological Considerations:

  • Self-reported outcomes — recall and social-desirability bias risk
  • Cross-sectional design — causal inference not possible

Abstract: OBJECTIVE: To report the prevalence of mental health symptoms and influencing factors in retired professional high contact team sport (HCTS) athletes. DESIGN: Mixed-methods systematic review. DATA SOURCES: PsycINFO, Embase, Medline, SPORTDiscus and Scopus were searched in July 2023 and March 2025. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Studies that investigated mental health and/or influencing factors within retired professional HCTS athletes were included. Studies that were non-peer-reviewed, could not obtain full text, used secondary data or focused on non-elite/individual/low-contact sports were excluded. RESULTS: 85 studies were included in the final review, comprising 53 996 participants (females; n=247, 0.46%) from six sports (Australian Football League, Canadian Football League, football/soccer, ice hockey, National Football League and rugby). Prevalence ranges varied for each condition; smoking (0.9%-16%), depression (3%-49%), anxiety (4.3%-42%), cannabis use (5%-15.7%), adverse alcohol use (6.4%-68.8%), opioid use (7%-23.6%), stress (8.7%-26.9%), illicit drug use (10%-63.2%), anxiety/depression (10.2%-39%) and adverse nutritional behaviour (23.8%-64.5%). Of the studies including M and SD of validated scales, scores for depression, anxiety and sleep disturbance were equivalent to population norms, whereas mild or higher scores were reported for stress and adverse alcohol use. Concussion, pain, injury, neurological factors and declined physical function were shown to have a negative influence on mental health. Both negative and positive influences were observed for: athletic identity, psychosocial support, retirement autonomy, life events, osteoarthritis, retirement and cognitive function. 48% of studies had good methodological quality; however, most studies were cross-sectional, relied on self-report measures and lacked follow-up data and female athletes. CONCLUSION: Retired HCTS athletes experience high levels of psychological distress and adverse alco

Clinical Perspective

🧠 This systematic review highlights significant mental health vulnerabilities in retired professional athletes from high-contact sports, documenting elevated rates of depression, anxiety, and cognitive concerns likely related to cumulative traumatic brain injury and loss of identity post-retirement. While the study appropriately catalogs these psychiatric sequelae, cannabis is not discussed as either a therapeutic intervention or potential confounding substance in this population, despite emerging anecdotal reports of athlete self-medication and the known risks of cannabis use in individuals with repetitive head trauma or pre-existing mood disorders. Clinicians should recognize that retired contact athletes presenting with mental health symptoms may have underlying neurobiological vulnerabilities that warrant careful assessment before recommending cannabis, and should instead prioritize evidence-based interventions including cognitive behavioral therapy, structured peer support, and medical evaluation for chronic traumatic encephalopathy. The complexity of disentangling primary mood disorders from organic brain injury in this cohort means that cannabis, while potentially appealing for symptom relief, risks masking neurodegenerative processes and may
