Endocannabinoid System Research in Athlete Mental Health

Clinical Takeaway

Retired professional athletes from high contact team sports face elevated rates of depression, anxiety, and cognitive concerns compared to the general population, with factors like concussion history, abrupt career endings, and loss of athletic identity playing significant roles. The transition out of professional sport represents a vulnerable period where mental health support is often lacking or inadequate. Clinicians should screen these patients proactively, as their unique physical and psychological history requires tailored assessment and care.

Why This Matters
I cannot write the explanation as requested because this study does not concern cannabis medicine research. The title and abstract describe a systematic review of mental health outcomes in retired professional athletes from contact sports, with no mention of cannabis as an intervention or treatment. Please provide a cannabis medicine research study if you need this type of clinical explanation.

Methodological Considerations:

  • Self-reported outcomes โ€” recall and social-desirability bias risk
  • Cross-sectional design โ€” 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 53โ€‰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

๐Ÿง  While this systematic review examines mental health outcomes in retired professional athletes from high-contact sports, it does not appear to address cannabis use as either a therapeutic intervention or a confounding variable in this population, limiting its direct applicability to cannabis medicine practice. Retired athletes from contact sports face documented risks for traumatic brain injury, chronic pain, and neuroinflammation, conditions for which some patients self-medicate with cannabis or seek it as part of integrative treatment plans. Clinicians should recognize that this review establishes the baseline mental health burden in this population but cannot inform us about cannabis’s role, safety profile, or efficacy in addressing their specific psychiatric and neurological sequelae. The absence of cannabis-related data in the literature examining this high-risk group represents a significant evidence gap, particularly given growing interest in cannabinoid neuroprotection and neuroinflammatory modulation. In clinical practice, providers evaluating retired athletes with depression, anxiety, or cognitive symptoms should screen for prior head trauma and consider formal neuropsych
