A brand new research, printed in JAMA Inside Drugs, led by researchers from the College of California San Diego Qualcomm Institute and Faculty of Drugs, reveals a dramatic enhance in sports activities betting and playing habit help-seeking for the reason that landmark Murphy v. NCAA Supreme Courtroom resolution in 2018 paved the best way for states to legalize sports activities betting.
“When the Supreme Court legalized sportsbooks—a venue where people can wager on various sports competitions—in Murphy v. NCAA, public health experts paid little attention,” mentioned the research’s senior writer John W. Ayers, Ph.D., who’s vice chief of innovation within the Division of Infectious Illness and International Public Well being, deputy director of informatics at UC San Diego Altman Scientific and Translational Analysis Institute (ACTRI), and Qualcomm Institute scientist.
“Now, sportsbooks have expanded from a single state to 38 states, with hundreds of billions of wagers, mostly online, coinciding with record-breaking demand for help with gambling addiction as millions seek help.”
Unprecedented development in sports activities betting
Because the 2018 Supreme Courtroom ruling, the research paperwork staggering development within the sportsbook business:
The variety of states with operational sportsbooks grew from one in 2017 to 38 in 2024.
Complete sports activities wagers skyrocketed from $4.9 billion in 2017 to $121.1 billion in 2023, with 94% of wagers throughout 2023 positioned on-line.
“Sports betting has become deeply embedded in our culture,” mentioned Matthew Allen, a third-year medical pupil. “From relentless advertising to social media feeds and in-game commentary, sportsbooks are now everywhere. What was once a taboo activity, confined to the fringes of society, has been completely normalized.”
The researchers word these developments are projected to develop, in no small half as a result of business’s funding in sportsbooks as the way forward for playing, as evidenced by Caesars Leisure’s rebranding to Caesars Sportsbook and On line casino.

A public well being blind spot
“Despite gambling addiction as a recognized disorder in the Diagnostic and Statistical Manual of Mental Disorders, it remains largely overlooked in health care and public health with no formal ongoing surveillance,” mentioned Kevin Yang, M.D., a third-year resident doctor within the Division of Psychiatry. “Without systematic surveillance, we are flying blind while millions bet on sports.”
To fill this hole, the analysis staff analyzed mixture Google search developments for queries that talked about playing, habit, addict, nameless or hotline, from January 1, 2016, by June 30, 2024.
“Many people struggling with addiction don’t openly discuss it, but they do turn to the internet for answers,” mentioned Davey Smith, M.D., professor of medication and director of ACTRI. “By analyzing search trends, we can gain real-time insight into the true scale of gambling addiction in the U.S.”
Document ranges of playing habit assist searching for
Parallel with the expansion in sportsbooks, web searches for assist with playing habit, akin to “am I addicted to gambling,” have cumulatively elevated 23% nationally since Murphy v. NCAA by June 2024. This corresponds with roughly 6.5 to 7.3 million searches for playing habit help-seeking nationally, with 180,000 month-to-month searches at its peak.
By state, the opening of sportsbooks persistently corresponded with elevated demand for playing habit assist searching for. Illinois (35%), Massachusetts (47%), Michigan (37%), New Jersey (34%), New York (37%), Ohio (67%), Pennsylvania (50%) and Virginia (30%) all skilled important will increase in playing addiction-related searches following the opening of any sportsbooks of their state.
“The significantly higher search volumes observed in all eight states make it virtually impossible that our findings occurred by chance,” mentioned Atharva Yeola, a pupil researcher on the UC San Diego Qualcomm Institute. “Statistically speaking, the probability of these results happening randomly is less than one in 25.6 billion.”

On-line sportsbooks drive even higher danger
The research discovered that on-line sportsbooks had a considerably higher influence on playing habit help-seeking than conventional brick-and-mortar sportsbooks. For instance, in Pennsylvania:
The introduction of retail sportsbooks led to a 33% enhance in playing addiction-help-seeking searches through the 5 months earlier than on-line sportsbooks launched.
When on-line sportsbooks turned out there, searches surged 61%—a considerably higher and extra sustained enhance that persevered for years.
“This pattern highlights the amplified risks associated with the accessibility and convenience of online sports betting,” added Adam Poliak, Ph.D., assistant professor of laptop science at Bryn Mawr School.
Coverage and public well being reforms wanted
“The expansion of legalized sports betting to always be at arm’s reach has outpaced our ability to understand and address its public health consequences,” mentioned Nimit Desai, a third-year medical pupil. “Our findings are a wake-up call for policymakers, health care professionals and public health advocates to act now.”
To mitigate the dangers posed by the growth of sports activities betting, the researchers advocate the next interventions be explored:
Elevated funding for playing habit providers utilizing sportsbook tax revenues to make sure accessible, evidence-based therapy applications.
Enhanced promoting rules just like these carried out for tobacco and alcohol to limit the place merchandise might be marketed and who might be focused.
Scientific coaching applications for well being care professionals to enhance playing habit analysis and therapy.
Stronger safeguards for on-line sportsbooks, together with betting limits, age limits, enforced breaks and restrictions on bank card use for playing.
Expanded public consciousness campaigns highlighting the dangers and warning indicators of playing, lowering stigma and inspiring early intervention.
Ongoing information sharing and analysis collaborations, uniting regulatory our bodies, well being care suppliers and regulators to evaluate the effectiveness of interventions and refine insurance policies in actual time.
“Sportsbook regulations are lacking because the Supreme Court, not legislators, legalized them,” concluded Ayers.
“Congress must act now by passing commonsense safeguards. History has shown that unchecked industries—whether tobacco or opioids—inflict immense harm before regulations catch up. We can either take proactive steps to prevent gambling-related harms or repeat past mistakes and pay the price later.”
