Gambling Harm Linked to Financial Stress and Mental Risks

Gambling Harm Is Broader and Deeper Than Problem Gambling Alone

16 September 2026

The harms of gambling are far more extensive and multifaceted than the addiction risks that have dominated its public perception. Expanding beyond those troubling consequences, gambling causes financial distress, mental health risks, social ripples, and even increases the likelihood of suicide, the evidence indicates.

In one of the most striking studies to date, the Institute for Clinical Evaluative Sciences in Ontario reported in 2022 that hospital emergency department visits related to gambling disorders nearly doubled over a 14-year period, reaching a total of 952 visits from 757 individuals. "By the end of the study period, gambling disorder ED visits were 154% higher than expected among males aged 10 to 29 and 116% higher than expected among males aged 30 to 44," the researchers found. Worryingly, almost three-quarters of the affected individuals were men, a sign that the impact may be acute in this segment of the population.

Study Lead Author Dr Shira Goldman suggested that the escalation in gambling disorder ED visits parallels the expansion of gambling opportunities in Ontario. After the province set up a government-run online-sports-betting monopoly and extended access to single-event betting, gambling opportunities became more plentiful, accessible, and exciting. Researchers tied those changes "to the rise in teens and young adults visiting emergency rooms because of severe gambling issues," Dr. Goldman said.

In an earlier study in 2020, a team in the United States found another way in which gambling may drive broader societal harm. Using credit bureau data, they found that in U.S. states where online gambling became available, credit card debt for households rose by 11.9%, equivalent to a cumulative increase of $800 per capita in those households. "Importantly, we find that this effect increases over time and is concentrated on households headed by those most vulnerable," wrote Lead Author Dr. [REDACTED], as the study was embargoed. "We find the greatest change in outstanding credit card debt among households headed by those with less education, non-white households, and households with a young man ages 21-45," the author added. These vulnerable groups also tend to be underprotected by debt relief systems, according to a 2020 study in the *Journal of Economic Perspectives.*

But the harms of gambling are not limited to financial distress and emergency medical care. Taking a broader view, a 2018 literature review in *Public Health* by Robert C. Owens described how gambling problems can ripple into the gambler's relationships, work, and wider life. "Research suggests a continuum of gambling problems, rather than an all-or-nothing either-or," Owens wrote. "Even lower-level gambling problems are linked to significant harms, such as financial losses, reduced savings, emotional distress, and relationship problems." A more recent analysis of all evidence to date came to a similar conclusion, calling for a "synergistic approach" to gambling risk that takes account of mental health, financial stress, and wider risk factors throughout society.

Taken together, the clinical, financial, and review literature tells a troubling story. Gambling is linked to harms that impact not just the individual problem gambler, but also the people around them, the public health system, and society as a whole. And while much more work is needed to estimate the scale of these harms, a sensible interpretation of the evidence is that they may be extensive.

In terms of policy, a sensible interpretation of these findings would be a fresh look at companies and individuals bearing the costs of these harms. Gamblers who end up with debt, mental health risks, or problems in other areas of their lives do not exist in a social vacuum, while their problems are not a free lunch for society—or for the gambling operators monetizing their vulnerability. How to address this who-pays-what market failure is not baked into these research findings. But they should caution healthcare authorities, legislators, and gambling operators that the current approach may not be a sustainable one, or one that serves the broadest societal good.
