Gambling is an activity in which people wager money or something else of value on the outcome of an event that depends on chance. It is a worldwide phenomenon that takes place in many forms, including pari-mutuel betting (horse and dog tracks, off track betting parlors, jai alai), casinos, lotteries, online gaming, credit card gambling, poker, dice games and even some video and board games. There are also activities that are not formally considered gambling but which can have a similar effect, such as insurance and betting against one’s own team (the latter being known as a ‘degenerate gambler’ by bookmakers) (Bolen & Boyd, 1968).

The term gambling has a wide variety of meanings and interpretations, depending on the cultural context in which it is used. The word is a common part of the vocabulary of many cultures around the world, with its roots in Latin. The noun, “gamble”, is derived from the Latin word for “fate”, and the verb, “to gamble”, is rooted in the Latin word for ‘to risk’.

Gambling can take many different forms, from the simplest form of placing a bet to the most complex. Generally speaking, it involves putting a bet on an event that is uncertain or that is based on chance with the aim of winning a prize. A bet may be made with real or virtual money, or with other things of value such as food, clothing or a car.

There are a number of factors that contribute to the development of problem gambling, including: impaired judgment, diminished mathematical skills, cognitive distortions and mental illness. However, it is important to note that gambling does not necessarily imply any of these conditions and many people who gamble do so responsibly.

For many, the attraction of gambling is that it offers a way to enjoy risk taking and excitement in a social environment, with the potential to win something valuable. It is also often seen as a way to relieve boredom, stress, anxiety or depression. The media also reinforces this perception by portraying gambling as fun, sexy and glamorous.

Problem gambling is generally viewed as a disorder with a range of severity from mild to severe, with the most serious cases falling into the diagnostic category of pathological gambling in the DSM-5 (American Psychiatric Association, 2013). A key distinction is that those who experience problem gambling have mixed motives; they have healthy reasons for gambling but these can be distorted by the darker motivations of addiction.

Research shows that if you know someone who is struggling with a gambling problem, it is important to talk to them about it and to offer support and advice. It is also useful to know about the effective treatment options available for gambling disorders, as well as local support services that can help them to get the help they need. For example, if they are experiencing financial problems, a debt management service could be helpful. They can also find out about free and local treatment programmes for gambling addictions, as well as information about how to get help in other countries.
