All prohibited substances are added to the Prohibited List because they meet two of the three following criteria:
- Use of the substance has the potential to enhance performance;
- Use of the substance can cause harm to the health of the athlete; and
- Use of the substance violates the spirit of sport.
While the CCES does not view cannabis as particularly performance-enhancing, we do have anecdotal accounts of athletes using it therapeutically with the intent to improve performance or recovery by managing pain, stress, or anxiety.
