Gambling is an activity where people place a bet on something that has value, but the outcome is determined at least partly by chance. It can involve betting on sports events, elections and horse races; casino games such as blackjack or poker; video games involving money (e.g., slots or video-draw poker machines); and speculating on business, insurance or stock markets.

Many people enjoy gambling for entertainment, and it is an important source of income in some countries. Some studies have shown that it can even increase happiness levels.

The most serious problem with gambling is when a person becomes dependent on it to the point where they are unable to control their behavior and live normally. A person who is addicted to gambling will lie, steal and borrow to fund their habit, often jeopardizing relationships and work opportunities. They may also be secretive about their gambling and continue to gamble despite mounting losses, attempting to “chase” their losses (American Psychiatric Association 2000).

Therapy can help compulsive gamblers change unhealthy behaviors and false beliefs that drive their addiction. Cognitive-behavioral therapy can teach a person to recognize and resist gambling urges, and address other issues that cause or worsen the problem, such as relationship, financial or career problems. A therapist can also recommend treatment for any underlying conditions that contribute to the gambling disorder, such as substance abuse or depression. In addition to family and individual counseling, groups like Gamblers Anonymous can provide support and assistance for a loved one struggling with an addiction to gambling.
