Research into self-help for problem gamblers has shown benefits. A study by Wendy Slutske of the University of Missouri concluded one-third of pathological gamblers overcome it by natural recovery. Anti-addiction drugs Self-exclusion Gambling self-exclusion (voluntary exclusion) programs are available in the US, the UK, Canada, Australia, South Africa, France, and other countries. They seem to help some (but not all) problem gamblers to gamble less often. Some experts maintain that casinos in general arrange for self-exclusion programs as a public relations measure without actually helping many of those with problem gambling issues. A campaign of this type merely "deflects attention away from problematic products and industries", according to Natasha Dow Schull, a cultural anthropologist at New York University and author of the book Addiction by Design. There is also a question as to the effectiveness of such programs, which can be difficult to enforce. In the province of Ontario, Canada, for example, the Self-Exclusion program operated by the government's Ontario Lottery and Gaming Corporation (OLG) is not effective, according to investigation conducted by the television series, revealed in late 2017. |"Gambling addicts ... said that while on the ... self-exclusion list, they entered OLG properties on a regular basis" in spite of the facial recognition technology in place at the casinos, according to the Canadian Broadcasting Corporation. As well, a CBC journalist who tested the system found that he was able to enter Ontario casinos and gamble on four distinct occasions, in spite of having been registered and photographed for the self-exclusion program. An OLG spokesman provided this response when questioned by the CBC: "We provide supports to self-excluders by training our staff, by providing disincentives, by providing facial recognition, by providing our security officers to look for players. No one element is going to be foolproof because it is not designed to be foolproof".
