Objective: To demonstrate the link between gambling, alcohol and drug
problems among Ontario adults and to present information on the relati
onship between expenditures on gambling and type of gambling with gamb
ling problems. Method: Using data collected in a 1994 telephone survey
of 2,016 randomly chosen Ontario adults, gambling problems are relate
d to the CAGE scale of alcohol problems and the ICD-10 measure of alco
hol dependence, as well as smoking, other drug use, and demographic va
riables. Descriptive tables based on crosstabulations and means are pr
ovided, as well as a series of 9 logistic regression models. Results:
The most significant predictor of gambling problems was the amount spe
nt on gambling in the preceding 30 days, with alcohol dependence on th
e ICD-10 scale and age also important predictors. Lottery players, com
pared to other gamblers, are more likely to be male, relatively less a
ffluent, older on average, more likely to report alcohol problems (but
not dependence) and be currently smoking. Conclusions: The results ma
ke clear that heavy drinking and drinking problems are associated with
higher levels of spending on gambling and reports of gambling problem
s. This leads to the suggestion that treatment programs for those with
gambling, alcohol or other drug problems should assess that possiblit
y of comorbidity, since the presence of more than one of these problem
s can significantly affect the success of treatment and contribute to
relapse.
