Australian tennis star Nick Kyrgios revealed that professional players are allowed to smoke marijuana while on tour, as the US Open got underway this week.
He warmed up for his opening-round match with a Q&A on Twitter, where he also teased that he would quit tennis if he won one of the biggest tournaments in the sport.
Before his match against Aljaz Bedene, Kyrgios was asked by a fan on Twitter: "Are you allowed to smoke weed on tour?"

The 21-year-old offered a simple one-word answer, replying: "Yep."
Although his comments are true, it's important that they're not taken out of context.
According to a WADA spokesperson, marijuana “is a prohibited substance for in-competition testing", but has never been prohibited out-of-competition.
Kyrgios didn't reveal if he personally smokes weed while off the court, but it doesn't look likely judging by his performance in the opening round of the US Open, as there was nothing laid back about his display against Bedene.
He beat the British number three in straight sets, securing a 6-4 6-4 6-4 victory which took just under two hours to complete.
The Australian will be looking to continue his fine form as he goes on through the tournament and may be offered a stronger challenge in the second round at Flushing Meadows.
Another player that's unlikely to smoke marijuana during his off time is Scotsman Andy Murray, who is one of the outright favourites to win the whole tournament after cruising past Lukas Rosol in his opening match.
He beat the Czech 6-3 6-2 6-2 to secure his place in round two and joins four other Brits in the next round.
Murray has had a successful year so far, winning Wimbledon earlier this summer and then following that up by winning gold in Rio at the Olympics.
