Gambling is defined as an activity where you wager something of value on an uncertain outcome. You may play poker, bingo, or even the lottery. You can also engage in games of chance, such as betting on sports teams or horse racing.

Gambling has a wide range of negative impacts on individuals, families, and communities. Gambling can cause stress, financial ruin, and family disintegration. It also can lead to the development of compulsive gambling. The problem can be especially damaging to young people.
