It’s standard for professional athletes to be tested for cannabis use, but does cannabis enhance physical capacity? Perhaps it impairs it? This review suggests neither. Researchers found no significant difference in athletic performance between chronic recreational cannabis users and non-users. Meaning, it is possible that athletic aptitude is not affected by cannabis use. Cannabis users can rest assured that physical activity will not be affected, and this could mean good news for professional athletes too: If future studies indicate that cannabis doesn’t affect athletic capabilities and official sport organizations stop its prohibition, then athletes could begin using it for therapeutic purposes.
