Data from the Gambling Impact and Behavior Study (GIBS), a national survey of 2417 U.S. adults, were examined by multivariate analysis to investigate characteristics of past-year recreational gamblers who participated in casino-only, non-casino-only, and both casino and non-casino gambling. Compared to non-casino-only gamblers, individuals who gambled in both locations had higher rates of alcohol use and abuse/dependence, lower rates of drug use, more frequent gambling, and larger wins and losses. Compared to casino-only gamblers, individuals who gambled in both locations reported less drug use, poorer subjective health, earlier age of gambling onset, greater frequency of gambling, and larger wins and losses. Compared to casino-only or non-casino-only gambling, gambling in both locations was associated with more frequent and heavier gambling. Findings suggest aspects of recreational gambling, such as gambling venue, may have important public health implications and should be considered in guidelines for responsible gambling.
