Gambling is the betting or staking of something of value (usually money) on an event that involves some element of chance and has the potential to yield a substantial prize. Events that may be the subject of gambling include lotteries, casino games, scratchcards, dice, horse racing, dog races, and sports events. In general, people gamble with money that they have, but some will also use credit cards, borrowing from family and friends, or even steal to fund their addiction.

The act of gambling has been around for thousands of years. Evidence of the earliest forms of gambling date to about 2,300 B.C., with tiles discovered in China that were believed to have been used for a rudimentary game of chance. Today, people gamble in a wide variety of settings, including casinos, racetracks, and online. Although most people who gamble do not have problems, a significant number of people develop compulsive gambling disorder, which is defined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) as a recurrent pattern of problematic gambling that leads to distress or impairment.

Many factors can contribute to the development of gambling disorders, including genetics, a person’s environment, and certain medical conditions. People who have a family history of gambling disorders are more likely to develop them themselves. In addition, a person’s age at the time of first gambling can influence whether or not he or she develops a problem. Typically, younger people start gambling earlier than older adults and are more likely to develop a problem.

One of the most useful research tools in identifying risk factors for problematic gambling is longitudinal studies. Such investigations can shed light on the dynamic relationship between an individual’s behavior and his or her gambling participation, thereby enabling the identification of factors that moderate and exacerbate an individual’s participation in gambling. Compared with other research designs, longitudinal data allow researchers to determine causality.

Gambling is not only dangerous for the person who has a problem, but also for his or her family and loved ones. When someone has a gambling problem, they often jeopardize their financial stability, work performance, and relationships. They often lie to their family members and therapists about how much they gamble, and may even borrow or steal to pay for their gambling habits. They often feel compelled to gamble even when they have spent all of their money, and may even return the next day to try to make up for past losses (“chasing” their losses).

In addition to receiving treatment for a gambling disorder, it is important to address any mood disorders that are contributing to the problem, such as depression or anxiety. There are no medications currently available that treat gambling disorders, but some can help with co-occurring conditions. Lastly, a person who has a problem with gambling should seek support from family and friends. It is not a sign of weakness to ask for help. In fact, it is often a sign that the person’s situation has become serious.
