What This Study Found

There is no direct evidence of cannabis as a performance-enhancing drug. Evidence for serious health harms in athletes is limited but potential for abuse and mental health issues should be considered. Cannabis use is associated with certain high-risk sports. The potential role of cannabis in pain management and concussion-related symptom relief deserves further attention.

Key Numbers

Cannabis use prevalence among elite athletes is not well-known. No evidence for performance enhancement. Limited evidence for both serious harms and benefits. Associated with high-risk sports.

How They Did This

Non-systematic literature review of Medline and PubMed for articles on cannabis/marijuana and sports/athletic performance.

Why This Research Matters

Cannabis is prohibited in competition by WADA despite no evidence of performance enhancement. As legalization expands, athletes and sports medicine providers need evidence-based guidance rather than policy-driven assumptions.

The Bigger Picture

The shifting cultural and legal landscape around cannabis is creating pressure to re-evaluate its place in sports. This review highlights that the evidence gap is large and cuts both ways - neither harms nor benefits in athletes are well-documented.

What This Study Doesn't Tell Us

Non-systematic review may miss relevant studies. Limited evidence base across all areas. Cannabis products vary enormously in composition. Athletic populations are understudied.

Questions This Raises

  • ?Should WADA reconsider cannabis prohibition given no evidence of performance enhancement?
  • ?Could CBD products benefit athlete recovery without performance concerns?
  • ?What are the risks of cannabis use for concussion management?

Trust & Context

Key Stat:
Zero evidence for cannabis as a performance-enhancing drug, but potential benefits for pain management and concussion symptoms deserve investigation.
Evidence Grade:
Preliminary - non-systematic review of a sparse evidence base.
Study Age:
Published in 2018. WADA has since raised the THC threshold and cannabis in sports remains under review.

Frequently Asked Questions

Does cannabis help or hurt athletic performance?

This review found no evidence that cannabis enhances performance. Evidence for serious harms in athletes is also limited. The most promising area for athletes is potential benefits in pain management and concussion symptom relief.

Why is cannabis banned in sports?

Cannabis is prohibited in competition by WADA, but this review found no evidence it enhances performance. The prohibition may reflect health and safety concerns rather than competitive fairness issues.
