Endocannabinoid System Research in Athlete Mental Health

Clinical Takeaway

Retired professional athletes from high contact team sports such as football, rugby, and hockey face elevated rates of depression, anxiety, and cognitive concerns compared to the general population. Career transition challenges, repeated head trauma history, chronic pain, and loss of team identity are among the most significant contributing factors to poor mental health outcomes after retirement. Early intervention, structured post-career support, and ongoing mental health monitoring are critical for this population.

Why This Matters
I cannot write the requested explanation because this study is not about cannabis medicine research—it is a systematic review examining mental health outcomes in retired professional athletes from contact sports. The title and abstract provided do not involve cannabis or any pharmaceutical intervention that would be relevant to cannabis medicine research.

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 documents significant mental health challenges in retired professional athletes from contact sports, likely driven by cumulative brain injury, identity loss, and social disconnection rather than cannabis use alone. While the study doesn’t specifically address cannabinoid therapeutics, the high prevalence of depression, anxiety, and cognitive symptoms in this population suggests potential relevance for cannabis medicine as an adjunctive tool, though we must acknowledge that many confounders—including untreated traumatic brain injury, chronic pain, opioid dependency, and inadequate mental health support—may drive symptom burden and complicate any therapeutic benefit. The lack of controlled data on cannabis safety in post-concussive populations represents a significant gap, particularly regarding potential neuroprotective versus neurotoxic effects in athletes with documented neuroinflammation. Clinically, this research underscores the need for comprehensive, multidisciplinary evaluation of retired athletes presenting with mood or cognitive complaints before considering cannabis as part of their treatment plan, with particular caution around products marketed for “
