Gambling involves betting something of value on a random event that cannot be predicted or controlled (for example, the outcome of a football match or a scratchcard). Skills can improve the odds of winning but the final outcome is still determined by chance. For instance, knowledge of the rules of poker may help predict a winner in a game of cards or knowledge of horses and jockeys might improve predictions about probable outcomes in a horse race. However, this does not prevent gambling from being addictive if it becomes more than just entertainment.

People gamble for a number of reasons: to win money, to relieve boredom or stress, or as a coping mechanism. It is important to remember that these motives don’t absolve the person from responsibility for their behaviour but can help us understand why they keep going despite the consequences of their actions.

When a gambler wins, their brain releases dopamine and this can make them feel good for a short time but the long term effects of problem gambling can be damaging to relationships and finances. For this reason, it is important to seek support if you or someone you know has a gambling addiction.

Treatment options include counselling and peer support groups like Gamblers Anonymous, which is based on the 12-step model of Alcoholics Anonymous. There are also residential or inpatient rehabilitation programs for people who need round-the-clock care. Other treatments, such as family therapy and marriage or career counselling, can help deal with the specific issues created by problem gambling and lay the foundations for a more stable future.
