endocannabinoid system clinical research: athlete mental health

Clinical Takeaway

Retired professional athletes from high contact team sports show notable rates of depression, anxiety, and other mental health challenges after leaving their sport. Factors such as head trauma history, loss of athletic identity, and poor social support significantly shape long-term psychological outcomes. Clinicians working with this population should screen proactively for both mood disorders and neurological contributors to mental health decline.

Why This Matters
I cannot write the explanation as requested because this study does not involve cannabis medicine research. The title and abstract describe mental health outcomes in retired professional athletes from contact sports, not cannabis therapeutics. Please provide a cannabis medicine study abstract if you would like me to explain its clinical relevance.

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 the substantial mental health burden among retired professional athletes from high-contact sports, yet the findings have limited direct relevance to cannabis medicine practice unless specifically examining cannabinoid use as either a risk factor or potential therapeutic intervention in this population. The study’s mixed-methods approach appropriately captures the complexity of post-retirement psychological challenges, including depression, anxiety, and cognitive concerns, though the abstract does not clarify whether cannabis use patterns or outcomes were among the investigated factors. Healthcare providers considering cannabis recommendations for retired athletes should recognize that while some patients may self-treat mood or pain symptoms with cannabinoids, the evidence base for efficacy in this specific population remains underdeveloped, and the neurobiological sequelae of repeated head trauma may interact unpredictably with cannabis exposure. Clinically, this work underscores the importance of comprehensive mental health screening and multidisciplinary care for retired contact sport athletes before cannabis is considered, and providers should routinely inquire about both the underlying drivers of psychological distress and any existing substance
