Casino gambling’s arrival in Pennsylvania a decade ago failed to produce the predicted surge in problem gambling behavior, according to a local nonprofit group.

Last week, the Council on Compulsive Gambling of Pennsylvania (CCGP) held its annual conference in Pittsburgh, at which the group presented statistics showing that the number of gambling addicts attending Gamblers Anonymous meetings is down from what it was 10 years ago, before the state authorized casino gambling.

What’s more, the volume of calls to state-run gambling addiction hotlines declined last year from the number of calls in 2015. And while about 1,500 individuals add their name each year to the Pennsylvania Gaming Control Board’s self-exclusion list, the pace of this growth has been steady rather than dramatic.

Elizabeth Lanza, the Board’s director of compulsive and problem gambling, told the Pittsburgh Post-Gazette that gambling addiction is “a huge, enormous problem for a very small percentage of people.”
