Gambling is an activity where participants place bets on events with a variable outcome. It may involve a bet on a team or player winning a football match, a slot machine or scratchcard. People gamble because they want to win money or other prizes. It can also have a number of psychological benefits, such as soothing anxiety and promoting curiosity and hope. However, gambling can also be harmful to individuals and society as a whole. It can cause serious harms such as financial stress, relationship breakdown and even mental illness. These problems can last a lifetime and have significant effects on family members and communities.

Despite these negative effects, the vast majority of gambling is responsible and the industry is regulated by governments and private entities. Many countries and states have legalized casinos, state lotteries and sports betting. It has never been easier to place a bet, with easy access to casinos, mobile and online gambling products. The widespread availability and promotion of gambling has increased the prevalence of harmful gambling and contributed to a sense of normalization.

There are many factors that can make someone more susceptible to gambling harm, including mood disorders (such as depression and anxiety), substance abuse, coping styles, social learning, beliefs, and environment. Psychological disorders, such as schizoid personality disorder, borderline personality disorder and narcissistic personality disorder, can also increase the risk of gambling problems. Other risk factors include low income, young people and males.
