Rates and correlates of problems associated with the use of alcohol are reported from the 1993 General Social Survey in Canada. Approximately 1 in 11 drinkers (9.2%) reported that drinking has had an adverse effect on his or her social life, physical health, happiness, home life or marriage, work, or finances in the past year. The most commonly reported problems concerned physical health (5.1%), and financial position (4.7%). Approximately one in eight drinkers (12.9%) had driven a car within an hour after consuming two or more drinks in the previous year. Furthermore, more than two of every five respondents reported that they had experienced some problem due to other people's drinking. In a multivariate analysis, age, marital status, gender, religious attendance and employment status were the strongest predictors of problem drinking. The number of heavy drinking occasions is a stronger predictor of drinking problems than is overall level of consumption.
