Novak Djokovic complained to the umpire that he could smell cannabis on court during his Rogers Cup semi-final win over French Jeremy Chardy.
After winning the first set, the world No 1 approached the chair, saying: “Someone is smoking weed, I can smell it, I’m getting dizzy.”
“Whoever it is, I hope he doesn’t come back tomorrow. He’s probably on the seventh sky somewhere.”
The Serb said he had also noticed the issue during a doubles match with partner Janko Tipsarevic on August 14.
“Yesterday in the doubles match, today again. Somebody’s really enjoying his life around the tennis court,” he joked.
Novak Djokovic went on to close out a 6-4, 6-4 victory against Jeremy Chardy in the semi-final.
