The name Ross Rebagliati brings two things to mind — Olympic snowboarding and marijuana.
The Vancouver-born athlete won gold at the first ever Olympic snowboarding competition in 1998. His medal was then stripped after he tested positive for THC, a chemical compound found in cannabis.
"It was a clash of a nightmare and dream coming true all at the same time," he told Stephen Quinn, host of CBC's The Early Edition.
The decision to disqualify Rebagliati was overturned and his medal was reinstated within a week of winning.
At that time, marijuana wasn't on the International Olympic Committee's list of banned substances although it was banned by other organizations like the International Ski Federation. The IOC followed suit in 1999.
Two decades later, marijuana is legal in several states in the U.S., while Canada is preparing to legalize recreational use in July.
"Athletes are living more and more in a cannabis culture," Rebagliati said.
International sporting regulations are still catching up, though.
Cannabis, hashish, marijuana and THC are on the World Anti-Doping Agency's prohibited list during competitions.
The threshold was relaxed in 2013 to allow for 150 nanograms of cannabinoids per millilitre of urine instead of 15.
Under the new rules, Rebagliati would not have had his gold medal retracted.
Rebagliati, a cannabis advocate, says the stigma around athletes using it as a performance-enhancing drug is slowly dissipating.
He started Ross' Gold, a dispensary franchise that promotes medical and recreational marijuana for athletes.
"It's just a perception of what people have in their minds of what performance enhancing means," he said. "It's all about wellness and mental wellness too, which is a big part of an athlete's life."
He said in particular the cannabis compound CBD, which is used to treat medical conditions like epilepsy, is gaining favour among athletes.
Unlike other extracts, it's not psychoactive and is used for sleep regulation, inflammation and anxiety.
"For me as an athlete, I use cannabis for all of those things, including motivation to keep [training]," he said. "CBD has really been the talk of the town."
As of the beginning of 2018, CBD is no longer considered a banned substance by WADA.
"I really think this was a step in the right direction for the cannabis industry worldwide," Rebagliati said.
