Gambling is an activity in which a person places something of value on the outcome of a random event. While most people participate in gambling as a social activity for fun and entertainment, a small number become too involved and suffer adverse consequences. These consequences can include family, financial, and mental health issues.

Occasional gambling is a harmless pastime, but when someone loses control of their money and spends more time than they should at the casino or online, it can be a problem. If you suspect that you or a loved one has a gambling disorder, speak to a counselor for referral resources in your area.

Gambling is a widespread international commercial activity in which participants wager something of value, such as money or other items of worth. Historically, the activity has been illegal in many jurisdictions but has continued to be a profitable and popular activity. Gambling can be conducted in casinos, on the internet or at private gaming events. The act of gambling can also involve the use of materials that have a perceived value but do not necessarily represent money, such as marbles, collectible game pieces like Pogs and Magic: The Gathering cards, or other objects of cultural significance. In addition to the possibility of winning or losing money, some gamblers may seek an emotional rush from the games and the prospect of a “big win.” The brain’s reward system is activated during gambling and this can contribute to problematic behavior.
