Gambling is the staking of something of value, usually money, on an uncertain event with awareness of the risk and in the hope of gaining. It varies from the simple buying of lottery tickets to the sophisticated gambling of the wealthy in casinos. In some cultures, it is considered to be a socially acceptable pastime and many people participate for fun, excitement and a sense of anticipation. However, for others, it is a serious addiction that can cause problems for themselves and their families.

Some people gamble because it gives them a natural high, a feeling of adrenaline and pleasure that they feel from the game and from winning. This is similar to the feelings they get from taking risks in life, such as going skydiving or driving recklessly. There are also some who find it hard to control their spending and are unable to quit gambling even when they are in financial trouble. They often find themselves sourcing for more funds by getting deeper into debt or even engaging in illegal activities. This can strain relationships and make loved ones feel betrayed, resentful and angry.

Gambling can have positive impacts on society when it is conducted responsibly. These benefits include creating employment opportunities, bringing in tax revenue for government operations and stimulating local economies. However, studies have mostly ignored the social impacts of gambling, focusing on only economic costs and benefits which are easy to measure. It is important that all impacts are assessed on their own and not combined, because this can lead to misleading conclusions.
