Gambling is a recreational activity in which people place something of value (typically money) at risk on an event with an element of chance, such as a football match or scratchcard. People choose what they want to bet on by choosing a number or event, which then matches up with ‘odds’ set by the gambling company – for example 5/1 or 2/1, and these odds determine how much money could be won if you are successful.
Problem gambling can cause harm to a person’s health and relationships, performance at work or school, and can lead to serious debt and even homelessness. It can also lead to a wide variety of other psychological problems, such as depression and anxiety.
Whether or not you are a gambler, you can take steps to protect yourself from gambling. You can limit the amount of money you spend by avoiding credit cards, putting someone else in charge of your finances, having your bank make automatic payments for you, closing online betting accounts and only keeping a limited amount of cash on you.
There is some evidence that problem gambling has negative effects on the gambler’s quality of life, but most research on this subject is sparse. Using a public health approach, it would be beneficial to examine the positive and negative impacts of gambling at the personal, interpersonal, and community/society level (Fig. 1). This can help researchers and policymakers assess the costs and benefits of different gambling policies.
