York United's Osaze De Rosario banned for one month after positive cannabis test

York United FC striker Osaze De Rosario has been suspended for one month after testing positive for THC, a component of cannabis.

De Rosario, the son of former Canadian international star Dwayne De Rosario, tested positive at an in-competition urine test on Oct. 1 and was sanctioned by the Canadian Centre for Ethics in Sport (CCES).

THC is included on the World Anti-Doping Agency's (WADA) list of prohibited substances.

The CCES notes that the WADA's prohibited list is not affected by changes in Canadian law that legalized recreational cannabis, adding cannabis is just one of many substances that are legal in Canada yet prohibited in sport.

"Last September, I unknowingly consumed THC after eating an unlabelled dessert at a dinner gathering I attended days before a match," De Rosario said in a statement. "I understand that cannabis is legal in Canada but is also prohibited in-competition in some professional sports.

The 22-year-old De Rosario is ineligible to participate in any capacity with York United during the suspension. He has three goals in 18 appearances this season and leads York with two assists and 27 shots.

York president and GM Angus McNab called the situation "regrettable."

"We are satisfied that Osaze consumed the THC inadvertently and out of competition," he said. "While we support his decision to comply with the CCES' sanction, it is disappointing that a sanction is required under these circumstances."

"We appreciate the important work done by the CCES, but we are disappointed that THC, a substance that is legal to consume in Canada, remains on WADA's prohibited list."

The suspension also drew reaction from Jozy Altidore, a former Toronto FC and U.S. international star forward.

"Change this rule ASAP.
