This article offers more questions than answers around the use of cannabis within sports and the authors are quick to indicate limitations of this review, such as that it is not targeted to a single specific sport, that no objective characteristics regarding the competitive level of the sport are provided and that no quantitative data on the possible pain and sleep outcome measures in elite athletic groups are provided.
Nevertheless, this article does build on the existing known literature supporting the use of cannabis to improve neuropathic and centralised pain, as well as sleep management.
While this is a very preliminary analysis, it raises some interesting questions about what performance enhancement is. Athletes may be using cannabis not for what it can do for performance, but rather for recovery.
Considerably more research is needed to verify whether cannabis is helpful or harmful in cases of sleep/ mood management, and recovery from specific training. But as cannabis use becomes more easily accessible world-wide, treating clinicians should be aware of reasons why some athletes would consider cannabis use.
