Montreal - World No 1 Novak Djokovic was unnerved by the smell of marijuana smoke on Saturday as he advanced to the final of the ATP Rogers Cup by defeating France's Jeremy Chardy.
During his 6-4, 6-4 victory, Djokovic complained to the umpire about the smell of marijuana smoke.
After the match he addressed the issue, which he said had distracted him in a prior match as well.
"Oh my God," Djokovic said. "You can't believe how bad it was.
"Whoever it is, he's pretty high and I hope he doesn't come back tomorrow. Because it's a pretty bad smell. I didn't enjoy it much."
The Serb said later that the same situation happened to him in a Friday doubles win.
"Yesterday in the doubles match, today again. Somebody's really enjoying his life around the tennis court" he joked.
"I think it stopped after a while. Whoever it was .... he was probably on the seventh sky somewhere.
"I felt I was playing better as I was inhaling."
Djokovic advanced in 80 minutes to win his 10th match against Chardy without a loss in the series, taking his 52nd match of the season against just three defeats.
