Gambling involves risking money or something else of value to predict the outcome of a game involving chance, such as scratchcards, fruit machines, two-up, roulette and horse and greyhound races. It can also involve betting on sports events or elections, or speculating on business, insurance and stock markets. Some people consider it fun and exciting but for many it can become a serious problem. There are a number of ways to gamble, some more risky than others, and the consequences can be severe.

Gamblers often have genetic or psychological predispositions that make them prone to going overboard. This can cause dramatic alterations in the way the brain sends chemical messages and leads to addiction. They are also more sensitive to losses than gains of equal value, so will invest more time and money in order to try to’make up’ for their losses, creating a vicious cycle.

The pleasure that gambling can provide is a result of the brain’s reward system being stimulated. However, like any other drug, repeated use can lead to a tolerance and eventually stop the same rewards being felt. Taking control back from the addictive behaviour can be hard, but there are plenty of resources available for help and support.

It is important to build a strong support network. This can be in the form of family and friends or peer groups such as Gamblers Anonymous, which is based on the principles of Alcoholics Anonymous. Professional help is also available, including one-to-one therapy, relationship and credit counselling, and specialist interventions such as family mediation or a debt management plan.
