Gambling addiction
In the United States, according to R. Volberg (1996), the number of “problem players” - addictive gamblers so dependent on slot machines that their lives are completely subordinated to this passion - reaches 5% of the population. Data from other researchers (Ladouceur et al., 1999) indicate that in the first half of the 1990s alone, the number of problem players in Canada increased by more than 75%.
