US Open Faces Marijuana Smoke Issue: The Governance Border Between a Grand Slam and a Public Park

Aryna Sabalenka raised her hand to complain to the umpire while serving in the fourth game of the opening set. The score was 30-0, she was leading 3-0, and the world number one fully controlled the match. But she stopped, not because of shoulder pain, not because of tactics, but because of the smell of marijuana smoke drifting down from the outer courts. That seemingly small moment is a symbol of a problem that has lasted for many seasons: the US Open is being surrounded by marijuana smoke from the public park beside the tennis center. I have followed the US Open for years and watched this issue return every summer in New York. When I sat on Court 5, where Sabalenka faced Kamilla Rakhimova in the third round, I realized this was no longer an isolated story. Many other players had spoken out: Maria Sakkari was bothered during a match in 2026; Casper Ruud complained about the practice courts; Katie Boulter, Fran Jones and Harriet Dart also pointed to the courts facing the park. Novak Djokovic, who rarely fuels controversy, confirmed the smell exists at the tournament. Alexander Zverev joked that the outer courts felt like Snoop Dogg's living room. Where is the problem? The US Open is the only Grand Slam whose tennis center is close to a large public park. The Billie Jean King complex sits right next to Flushing Meadows-Corona Park, where New Yorkers have had the right to use recreational marijuana since 2026. The USTA bans smoking on its grounds, but cannot ban people outside the fence. The organization admitted it can only cooperate with the NYPD and park authorities, not control what happens just outside the border. This is a structural governance gap, not a matter of effort. I want to dig deeper. In injury and sports-data analysis, I always start with the question: where did we measure incorrectly? Here, the right question is not whether marijuana hurts tennis, but how badly we have misread the competitive fairness of the environment. Data never lies; only our way of reading it is wrong. Looking at the numbers, I see three things. First, the smoke is concentrated on outer courts facing the park, not on Arthur Ashe or Louis Armstrong stadiums. That creates a random court disparity: a seeded player scheduled at night on center court does not face the same inconvenience as a mid-ranked player during the day on an outer court. Court 17, where Zverev once played, is often cited as a hot spot. If we measured focus disruption or the number of mid-point stops, the outer courts would clearly have higher numbers. Second, the complaint rate is rising. In 2026 Sakkari stopped to talk to the umpire about the smell. In 2026 Sabalenka did the same at an important moment. Katie Boulter said it happens not just in her own match but also on the practice courts. Djokovic says the smell seems to bother some players more than others, but when so many players speak out, the problem is no longer rare. One incident may be random; repeated incidents are a pattern. Third, and this is what I find most interesting, the effect on match results remains unproven. Sabalenka still won easily despite the disruption, extending her US Open winning streak to 16 matches. Casper Ruud, Zverev and Djokovic did not lose because of smoke. Sakkari said she did not want to use the smoke as an excuse. So is the media exaggerating? Perhaps. But that does not mean the issue should be ignored. I believe in verified numbers, but I also believe in nuanced thinking. If we simply count complaints, we miss the blind spot. Who is hurt the most? Not Sabalenka, not Djokovic, but lower-ranked players, those in qualifying or early rounds on outside courts. They do not have large teams, they cannot easily rent private practice courts off campus, and they have less voice to force action. If one has asthma or a respiratory condition, the outcome could be not just a loss, but a medical and liability issue. What can the USTA do? I have watched tournaments for years and know that the solution is not just more security guards. Partnering with the NYPD is useful, but New York police are unlikely to target cannabis users in the park during a tennis tournament. Physical barriers and air filtration on outdoor courts are not cost-effective. Adjusting the schedule to reduce exposure during peak hours is possible but complex and risks new inequalities. I do not believe in luck; I believe in verified numbers. But paradoxically, this issue lies in a place where there is no data. Nobody is measuring smoke density at each court. Nobody is recording how many times a player complains during a match. Nobody is tracking double-fault rates on courts near the park to compare with others. With those numbers, we would know the true impact. Right now, all we have are subjective feelings from players. Data never lies; only our way of reading it is wrong. Our current reading blames marijuana or the police, but the gap lies in our measurement. This season, other Grand Slams can learn from the US Open. Australia, Wimbledon and Roland-Garros are not adjacent to huge public parks in this way, but other U.S. states and Canada also legalized cannabis. If this trend spreads, many tournaments will face the same issue. The root problem is not marijuana itself, but the tennis industry's ability to respond to an environmental phenomenon outside its direct control. Think further: if a player officially asks for a match to be suspended because of smoke, does the USTA have the authority to change anything? Nobody has gone that far, but many top players speaking up for years could be the precursor for a bigger event. Instead of turning this into an annual joke, we should see it as a new risk for sport in the legalization era. For Sabalenka, this can be a strange detail in her title defense. But for players without a big name, for those trying to reach the second or third round, marijuana smoke is not a joke. It is a distraction on courts that already have fewer spectators. We often measure success by score, but forget the quality of playing conditions. Paris, London and Melbourne do not have this problem, so why does New York? The answer lies in the gap between cannabis culture and urban planning. I have watched tennis for years and learned that an on-court incident almost always reflects a larger off-court truth. Marijuana smoke at the US Open is not a story about inconsiderate users, but about institutional response. The USTA cannot solve it alone, but they can still build a better response system: measuring air quality at each court, logging complaints systematically, and talking with local authorities to create dedicated smoking zones far from the fence. If no one measures, no one knows how bad it is. A risk model saves no one; it only tells you where to look. The US Open will remain one of the biggest events of the year. Marijuana smoke will not lower its commercial value or drive away stars. But the entertainment angle may hide a health and equity issue. If a top seed is disturbed, the story lasts a day. If a player ranked 200 starts coughing, has bronchospasm and retires, will people see it differently? I do not want to wait until then. I want to look at the data now. The final question for the organizers: are they ready to listen to an unknown athlete who says they cannot breathe normally on court? Or will the issue only get attention when Djokovic or Sabalenka use their influence to demand changes? Fairness in sport does not only come from measuring time and double faults, but also from ensuring every player can compete in an environment free from unwanted smoke, no matter how legal that smoke is.
