Gambling and health

Updated: Jan 18, 2022

Publicly the industry denied and continues to deny the significance of gambling harm on a population level. This refusal to accept the reality is compounded by the industry's lack of funding in public health research, despite the WHO commenting on the need to prioritise gambling-harm on agendas due to the magnitude of harm from gambling being comparable to the harm accrued by alcohol-use disorder or major depressive disorder.

Harms in affected others challenge the industry in two ways. First, measures to raise awareness and prevent gambling harms in individuals who do not gamble will reduce the appeal of gambling and contribute to its social unacceptability. Second, the 'freedom to gamble' argument is confounded if individuals who do not gamble are harmed.

The industry has largely refused to acknowledge the significance of harms in affected others, individuals who gamble and suffer low-risk harms, moderate-risk harms, and legacy harms due to previous gambling. This situation has not been helped by the chronic underfunding and lack of independence in research, education, and treatment.


“The gambling-related burden of harm appears to be of similar magnitude to harm attributed to major depressive disorder and alcohol misuse and dependence. It is substantially higher than harm attributed to drug dependence disorder.”

WHO: The epidemiology and impact of gambling disorder and other gambling-related harm 2017 1

Gambling addiction was first formally recognised as a mental disorder by professionals in the US through the Diagnostic and Statistical Manual of Mental Disorders-III in 1980. Over the past two decades, gambling harm has emerged as a pressing public health issue globally. Domestic and international studies have reported statistical links between gambling harm in adults and suicide, mortality, and poor health. When faced with evidence of the links of gambling and harm to health, industry lobbyists have commonly steered away from admitting any responsibility; instead, they have promised research, reform, or reiterated commitments to safer gambling standards. Moreover, the industry has worked to associate itself with the NHS and other health organisations.

Gambling harm may be experienced by individuals that gamble, affected others of people who gamble, and by communities. Research from Australia in 2016 reported a taxonomy of harms over eight domains: financial, relationship, emotional, health, cultural, work or study, criminal activity, life course and intergenerational harms.

Responsible gambling mantras have largely replaced public health messaging in Great Britain. Meanwhile, ideas of risk-free gambling and safer gambling have been furthered. Current safer gambling ads seldom reflect the significance of gambling harm, especially on affected others, due to them being industry-supported. Similarly, specialist treatment options and awareness among health care workers remain challenges and are limited by such efforts being primarily managed with voluntary donations.

Moreover, public health research in New Zealand and Australia have explored the significance of gambling harm on quality of life by reporting disability weights. These disability weights allow researchers and public health stakeholders to understand the significance of gambling harm on the individual and the population through comparison to other health states. Based on this research, a WHO report found an "urgent need to place gambling on national and international public health agendas", among other things.

At the time of writing, little is known about the significance of harm in young people, individuals who previously gambled, and former affected others (legacy harm). Whereas gambling-harm has featured in Australia's Monash guidelines for healthcare professionals for over a decade, the UK's National Institute for Health and Care Excellence (NICE) is yet to begin reviewing the evidence on gambling harm.

What the industry said?

Michael Dugher, CEO of the Betting Gaming Council 12

"The UK's addiction rate stands at 0.5% of the adult population, which is low compared to the international standard. The rates have also remained 'broadly steady around or below one percent for the past 20 years."

Dugher frames the topic of gambling harm on the segment of adults suffering the most severe harms due to gambling in the past 12 months while omitting the experiences of affected others, individuals who previously had gambled, and individuals experiencing subclinical levels of gambling harm. Moreover, there are significant concerns with measuring gambling harm using self-completion forms included in health surveys, and as such, the stated 0.5% is expected to be a significant underestimate.

The industry rarely comments on affected others as it recognises that this is likely to be the most damaging to their public relations strategies. Instead, the industry benefits from the fallacious societal stigma that gambling addiction is the individual's fault; however, the same cannot be easily argued for loved ones, especially the children who suffer harm.

Gambling Commission in a briefing paper for Local Authorities and local Public Health providers February 2018 13

“The numbers of those who experience harm as a result of gambling by others will be considerably greater than the number of people who harm themselves.”

“These are not small numbers. They suggest a significant public health issue which has received remarkably little attention relative to other population level concerns.”

The Gambling Commission makes clear why gambling harm should be considered as a public health issue. Identifying gambling as a significant public health issue is in direct contrast to how the Gambling Commission falls under the remit of the Department of Culture, Media and Sport (DCMS) instead of the Department of Health and Social Care.

Michael Dugher, CEO of the Betting Gaming Council 14

“NHS Charities said it wouldn't be possible for betting co's to make a direct donation, but they were happy for us to donate all the profits from this special fun virtual Grand National to help the NHS at this difficult time. Most people agree there's nothing wrong with this...”

Dugher states that NHS Charities were not accepting a direct donation from the gambling industry. This quote demonstrates the BGC’s interest in associating with the NHS for the 4.8m viewers who tuned in to watch this virtual horse race which raised £2.6m. 15

“You don’t have to bet. If you don’t want to have a bet, please make a donation direct to NHS Charities. But millions of people do enjoy an occasional flutter & do so responsibly & safely.”

Dugher argues that millions of people enjoy an occasional flutter while ignoring the millions that suffer gambling harm and the individuals who gamble frequently and make up significant amounts of the industry’s profit.

Betting and Gaming Council 16

“Suicide is a complex issue and the examination of any links to gambling or disordered gambling requires great care and sensitivity. We suggest that a collaborative and careful approach to understanding linkages is required. The aim of research should be to explore what is clearly a difficult subject and provide pragmatic solutions.”

The BGC creates an aura of doubt around gambling-suicide, despite evidence from studies across the world reflecting that individuals with gambling-disorder are many times more likely to suffer from suicidal harm.

“Through continued funding by our industry over more than 20 years, these charitable services are able to provide free of charge treatment, support & advice services for anyone affected by gambling.”

The BGC boasts of their voluntary funding for treatment services for harms caused by their industry. Thus, the industry demonstrates that treatment services are available due to the industry's generosity while ignoring issues with treatment access, awareness, and chronic underfunding.

Mark Etches, CEO of GambleAware 17

[Britain was] “in great danger of sleepwalking into a future public health storm over gambling-related harm”.

Etches reflects on the numbers of 11–16 year olds with a gambling disorder and signifies concern for the future. Contrastingly earlier that year, evidence reported on by the World Health Organisation (WHO) reflected a worryingly significant ongoing neglected public health crisis with an “urgent need to place gambling on national and international public health agendas”. 1
