MONTREAL (AFP) - World No. 1 Novak Djokovic was bothered 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."

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.

A break of serve in each set was enough for the top seed to stay comfortably in control of his 49th-ranked opponent, playing a Masters semi-final for the first time.

"It was good to get a quick win likes this," said Djokovic.

"I was glad to do it with two breaks. Jeremy played well, but I was totally concentrated and stayed in control of the baseline.

"I'm excited about reaching the final. All of these events are important and it would be great to win another final this season."

Djokovic will be looking for a 25th Masters 1000 title in the Sunday final.

He leads Murray 19-8 and hold a 4-2 record over Nishikori in career rivalries.
