Online gambling allows people to place bets on sports events, casino games, poker or lottery-type games. Some states regulate these activities and provide for licensed operators and fair play. Others prohibit the practice, and some even prosecute people who gamble online without a license or in violation of state law. However, most of the gambling sites are run by reputable companies that offer fair play and allow players to set loss limits. They also promote responsible gaming and make it easy to self-exclude from the site when necessary.
The Internet has made it easier for individuals to gamble than ever before. The first online casinos appeared in the late 1990s, and a number of major gambling companies have established a presence on the Web. Some of these sites have a physical location in the United States, but most operate through servers located in offshore jurisdictions such as Antigua and Barbuda or the Caribbean islands. The legality of online gambling is a hotly debated issue. Some states, such as Utah and Hawaii, ban the activity entirely because of their religious beliefs; other states, such as New Mexico, have loosened their laws to permit it.
Many Web-based gambling sites require a visitor to download software from the site before they can play for real money. Once downloaded, the software will run through a program at the Web site and allow the player to interact with other users. The software will also track a user’s winnings and losses. Winnings are then either deposited into the user’s account or paid via a check sent to the winner.
Most research on the effects of online gambling has used cross-sectional designs, which do not allow for the determination of causality and are heavily reliant on self-report. Despite these limitations, several studies have found that for some problem gamblers, Internet gambling is the proximal cause of their problems. For example, George T. Ladd and Nancy M. Petry conducted a study of Internet gamblers among people seeking free or reduced-cost medical and dental services at the University of Connecticut. The researchers found that a large proportion of the respondents reported having gambled at least once in their lives. Some had gambled recently, and others had gambled on a weekly basis.
They reported that during the COVID-19 pandemic, 12% of their sample gambled less frequently, 33% stayed the same and 14% began gambling more frequently. This increase in gambling was unrelated to depression, anxiety, alcohol use or sex and was associated with a greater severity of gambling problems. The authors suggested that the COVID-19 pandemic had a significant impact on gambling behavior and that this may have been because of changes in psychological motivation. The authors further suggested that further research is needed into the impact of the COVID-19 pandemic on gambling behavior and regulation. A broader range of data collection methods, including longitudinal designs, should be used in future studies. The research should focus on a broader population of online gamblers and include more rigorous methods of analysis.
