Gambling is the act of risking something of value (money or assets) on an event that has an uncertain outcome with the primary intent to win money or material goods. Gambling includes buying lottery tickets, playing poker or casino games for money, betting on sports events, keno, bingo and baccarat.

Problem gambling is associated with significant harms to health including relationship breakdown, family violence, mental illness and suicide. Harms also include the diversion of funds from essential household spending to gambling, leading to food insecurity and housing problems. These are often compounded by the social stigma, financial stress and criminal activities of some gamblers. The legacy of gambling harm can extend through generations and can have a serious impact on families, children and communities.

A clear definition of gambling helps to establish appropriate regulatory measures that protect people and ensure fairness. It is also a crucial factor for addressing the global expansion of legal, illegal and offshore gambling markets. This poses challenges to the delivery of international agreements and commitments on health, poverty eradication, sustainable development and other global priorities.

Gambling can be a fun activity, but it is important to understand the risks. The act of gambling triggers a number of biological responses in the brain, which can lead to addictive behavior. These include the release of dopamine, a neurotransmitter that makes us feel excited and euphoric when we win. However, it is important to remember that the odds of winning are less than the odds of losing. This is because of the ‘house edge’, which is built into all gambling games.
