Generally, athletes who take drugs do it for one reason. It's so they can compete at the top of their sport and earn more money.
Curling is not a sport where there's a lot of money going around, so it'll probably come as a surprise to hear that a Canadian curler, Matt Dumontelle, has been suspended by the Canadian Curling Association for two years after he tested positive for Methandienone Metabolites.
The positive test happened after the gold medal game in the Men's World Championships in Victoria which Canada won. Dumontelle was only an alternate player though, so Canada still retain the gold.
Quoted on TSN.ca, Dumontelle said:
"I take full responsibility for the findings of the positive test at the World Championship in Victoria. I am truly sorry for letting down my teammates, the Canadian Curling Association and curling fans across Canada,"
"I was taking a workout supplement that I believed was safe; clearly, it was not and I regret that decision. I had no intentions of trying to 'beat the system.'
I was made aware by our Canadian Curling Association High Performance staff of my responsibilities to respect and follow the rules as set down by the World Anti-Doping Agency.
At the end of the day I accept that it was, and is, my responsibility to make sure that I am playing by those rules."
I guess all that sweeping requires real stamina.
