Gambling is an activity in which people place bets on events with uncertain outcomes, such as the outcome of a football match or a scratchcard. The act of gambling evokes a sense of anticipation and excitement, and it can relieve boredom by providing an alternative to other pastimes such as watching television or playing video games. Furthermore, gambling has the potential to stimulate brain activity by encouraging the development of new neural connections. It can also help people develop social relationships with others who share the same interests, for example, by encouraging them to meet in person and play casino games.

Many studies have identified negative effects of gambling at the individual level, including financial, labor, and health/wellness impacts. However, the literature on interpersonal and community/societal level costs is limited. Interpersonal costs include invisible costs that affect a gambler and their significant others, while societal/community level external impacts can be measured using measures such as quality of life weights and the cost of problem gambling.

In addition, gambling can promote economic benefits at the local level. For example, it helps generate revenue for governments from taxation. It can also provide employment opportunities, such as in casinos and sports betting sites. These jobs can support the local economy by creating more income and reducing unemployment rates. Furthermore, gambling can be a fun way for people to interact with one another, such as when playing poker or blackjack. The social interactions can reduce stress and help people feel more connected to their community.
