Gambling is risking money or something of value on an activity based on chance, such as playing games like lottery tickets or scratch-offs, video poker, or betting with friends. It has existed in almost every culture, and is sometimes a part of local customs or rites of passage. It is estimated that the global gambling industry is worth $335 billion.

While most people gamble for fun, some become compulsive about it, and continue gambling despite significant negative personal, family and financial consequences. Compulsive gambling is a mental health disorder, and is often triggered by depression or other mood disorders. It also carries the highest suicide risk of any addiction or mood disorder, and can be made worse by stress, drug use, or other lifestyle factors.

Scientists believe that problem gambling is partly a result of the brain’s reward pathway being modified to respond to the excitement and dopamine release that comes from gambling. It’s a bit like shooting basketballs into a net, where your brain rewards you for each successful shot, encouraging more skillful behaviours.

Keeping control of your finances is a key strategy to help you stop gambling. You can reduce your risk by: taking control of credit cards, putting someone else in charge of your money, closing online betting accounts, and carrying only a small amount of cash with you at all times. Seek support from a family member or friend, and consider joining a gambling peer group like Gamblers Anonymous.
