Gambling is an activity in which a person risks something of value on an event that is determined at least in part by chance, with the intent to win something else of value. While most people who engage in gambling do not experience problems, a small percentage develops an addiction to the behavior and experiences serious consequences. While most adults and adolescents have gambled, some do not know that buying a lottery ticket, playing bingo, betting on office pools, or even placing bets with friends are all forms of gambling. The practice can also lead to problems in the workplace and home, including conflicts with coworkers, strained relationships, and increased stress levels.

While gambling can be a fun way to socialize with friends, it can also lead to debt and other financial issues. Problem gambling has a direct effect on a person’s financial well-being, which can affect their ability to meet basic needs and may even threaten their housing or employment status. It can also cause depression and anxiety, as well as increase feelings of powerlessness. Some people find relief by pursuing other activities, such as exercising, spending time with friends, or engaging in cognitive behavioral therapy.

In the United States, 2.5 million adults (1%) are estimated to have a severe gambling disorder in any given year. Many more people, between 5-8 million (2-3%), have mild or moderate gambling disorders. Those with serious disorders may be unable to control their gambling and experience significant distress or impairment in their everyday lives.

Some factors that contribute to the development of a gambling disorder include family history, age, gender, and education level. Psychiatrists note that young people, especially boys and men, are particularly vulnerable to becoming compulsive gamblers. They often have more to gain with a large win, which can result in the compulsion to gamble again and again. In addition, these individuals may be attracted to video and mobile gaming that require a high level of concentration and strategic thinking.

While gambling has its own unique set of impacts, these can be structuralized into three classes: negative and positive; costs and benefits. Negative impacts occur at the personal and interpersonal levels, while positive impacts are observed at the societal/community level. The most common method for assessing costs and benefits involves health-related quality of life (HRQL) weights, or disability weights, which quantify the intangible effects on a person’s well-being. This is an important tool for analyzing the costs and benefits of gambling, both on gamblers themselves and on their significant others. This methodology can help inform gambling policies that will reduce the costs and maximize the benefits.
