Cannabis smell at US Open is distracting - Boulter

British number one Katie Boulter has complained that the smell of cannabis is putting her off her game at the US Open.

On Sunday, the final major of the season begins at Flushing Meadows in New York, where cannabis is legal for adults aged 21 and over.

Though smoking is not permitted on site, the smell of cannabis wafts on to court from nearby Corona Park and has bothered a number of players in previous years, including Novak Djokovic and Alexander Zverev.

Boulter, who is preparing to face American wildcard Carol Young Suh Lee in the first round, says it is possible to smell cannabis "a lot" on the practice courts.

"I'm not a huge fan of it," said Boulter, the world number 60. "I know a lot of players have complained on some of the specific courts. I've played on one before and I did smell it during my match.

"It's something that I wouldn't like to smell in the middle of my match. I'm trying to focus and then obviously, it takes you out of the moment and you really don't want to.

"You don't need distractions. So yeah, I wasn't a huge fan of it."

The smell of cannabis has been a persistent issue at the US Open.
