Gambling has moved far beyond the casino floor. It now sits in mobile apps, sports broadcasts and social media feeds, reaching people in places where the activity may even be prohibited by law. Globally, an estimated 5.5% of women and 11.9% of men experience some level of harm from gambling, and the consequences extend well beyond the individual who places the bet.
A Public Health Issue, Not Just a Personal Choice
Gambling disorder is now classified alongside substance use disorders in both the DSM-5 and ICD-11, reflecting growing recognition that it functions as a behavioural addiction with serious clinical dimensions. The ICD-11 defines it through three markers: impaired control over gambling, escalating priority given to it over other life activities, and continued gambling despite clear negative consequences. But harm does not begin only at diagnosis. Households can experience food insecurity, housing instability and reduced access to healthcare well before any clinical threshold is met, simply because money meant for essentials is diverted toward gambling.
The ripple effects are wide. Research cited by public health bodies suggests that for every person gambling at high-risk levels, roughly six others - often family members who do not gamble themselves - are affected. In kinship-based cultures, including many Indigenous communities, that number is likely higher still. A Swedish study found people with gambling disorder were fifteen times more likely to die by suicide than the general population, and in the Australian state of Victoria, at least 4.2% of suicides were linked to gambling.
Why Self-Regulation Keeps Falling Short
The gambling industry has long favoured "responsible gambling" as its preferred regulatory framework - an approach that places the burden of moderation on the individual rather than on product design or market structure. Evidence suggests this model is frequently ineffective, particularly when protective tools like self-exclusion or spending limits remain optional. Electronic gambling machines, for instance, can be engineered with features that encourage extended, near-continuous play, while warning messages are sometimes framed in ways that subtly normalize continued use rather than clearly communicating risk.
Unlicensed and offshore operators compound the problem. Because there is no global consensus on how to regulate online gambling, consumers can often access unregulated platforms regardless of local law, undermining consumer protections and depriving governments of legitimate tax revenue.
What Effective Prevention Looks Like
Public health experts point to population-wide interventions as more effective than approaches relying on individual willpower. These include:
- Ending gambling advertising, promotion and sponsorship in sport and cultural events
- Mandatory, rather than voluntary, account registration with binding pre-commitment limits
- Universal loss limits, maximum bet sizes and required breaks during play
- Well-resourced regulatory enforcement against non-compliant operators
- Reducing the stigma that discourages people from seeking help
Treatment uptake remains strikingly low - an estimated 0.14% of the population seeks formal or informal help for gambling problems, a gap often attributed to shame and the misplaced belief that harm reflects personal failure rather than product design.
The Regulatory Tension Governments Face
Legalized gambling markets generate substantial tax revenue, which can create a structural disincentive for governments to impose stricter controls. Industry groups, meanwhile, actively lobby against high-impact regulation and have been shown to influence research funding and agendas. The World Health Organization has flagged gambling's potential to undermine progress on several Sustainable Development Goals, including those tied to health, inequality and strong institutions, and is coordinating international expert groups to improve diagnostic tools and share effective regulatory models - particularly for lower-income countries where commercial gambling is expanding quickly.
