Pathological gamblers are most likely to get in financial trouble by betting on sports, poker, horse races, and lotteries, according to a study from the University of Sydney.
Researchers from the Department of Psychology interviewed people in rehabilitation centers being treated for compulsive gambling. Over 85% had been betting on sports and no-limit poker games. Playing poker while intoxicated raised the risk for financial difficulties by 15,000%. Blackjack games were mentioned by only one percent in the study.
