Gambling is an activity in which people risk something of value (like money) on an event that has a high chance of occurring, in the hope of realizing a profit. It has existed in virtually every society since prerecorded history and is incorporated into local customs and rites of passage. While the majority of people who gamble do so without problems, a significant subset become overly involved and develop gambling disorder, an addiction that is recognized by the Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) as a serious clinical problem with lasting and debilitating effects on a person’s quality of life.

The risk of developing a gambling disorder is higher among those who are poor, have low self-esteem or lack effective social support systems. It is also more common in males, adolescents and those who work in casinos or betting shops. In addition, genetic factors can affect the way a person processes rewards and controls impulses.

The first step in recognizing a problem with gambling is to recognize the warning signs. These include: (1) secretive or evasive behaviour (e.g. lying to family members about how much is being gambled, concealing purchases); (2) frequent urges to place bets; (3) difficulty controlling the amount of money spent or putting it aside for other purposes; (4) constant feelings of guilt and anxiety; (5) attempts to cover up losses by borrowing money, forging checks or stealing; and (6) repeated efforts to win back lost funds (also known as “chasing”). Problem gambling has been linked to increased rates of suicide, especially among young people.
