All WSWC and Wake Canada National Championship events are subject to drug testing by the Canadian Centre for Ethics in Sport. This is outside the control of WSWC and Wake Canada. However, it is possible that CCES will show up for drug testing at any nationals event.
Since Monster Wake Nationals Presented by Nautique in Bala, ON are a month away, this is just a friendly reminder that Marijuana is a banned substance. Marijuana is a common source of doping violations in all sports. Traces of it can remain in the body for a month or more. For more information check out the CCES website.
All banned substances can be found here on the prohibited list.
