Brent Laing, who plays for the Canadian men’s team, said he had no idea how meldonium would enhance performance.

“Outside of beer and Advil, that’s the only painkillers I’ve ever heard of for curling,” Laing said. “I imagine it wasn’t that. Hopefully not, or else I’d be in trouble.”

Russia was barred from the Olympics in December after an investigation into a state-backed doping program. The International Olympic Committee, however, later cleared more than 160 Russian athletes to compete here in Pyeongchang as Olympic Athletes From Russia under the Olympic banner.

Moiseeva, whose team lost to Switzerland on Monday morning, said she thought about reaching out to Krushelnytsky and Bryzgalova but decided against it. She would not have known what to say to them, she said.

“It’s impossible to believe,” Moiseeva said in Russian, adding: “We delighted in the results and in the success of the pair. It’s impossible to believe that someone could do such a thing and sleep calmly at night and ruin not just the life of one person but those of a large number of people.”

She went on, “We always said it was so great to be involved in a sport where you wouldn’t have such scandals because this is simply not necessary. You don’t need to be faster, higher and stronger. You need to be more accurate, not necessarily stronger. I can’t even understand what medication would be necessary and what you could use it for in curling. For that reason, it’s very hard to believe.”
