The 8.4% prevalence of alcohol abuse/dependence estimated by the present study (13.1% for men and 4.1% for women) is above the average value of 6% that Galduroz et al8 (2003) found in a survey performed in 1999.
Dependence on alcohol and tobacco also is correlated: People who are dependent on alcohol are three times more likely then those in the general population to be smokers, and people who are dependent on tobacco are four times more likely than the general population to be dependent on alcohol (3).
