Age differences in alcohol and cocaine expectancies and attitudes

Positive and negative expectancies regarding the behavioral effects of alcohol and cocaine were assessed and used to predict attitudes toward their use across four age groups (5-7, 8-10, 11-14, and 18-25, N = 121). Regardless of gender and minority status, children and early adolescents appeared to overgeneralize their beliefs about alcohol to a less familiar drug, cocaine, perceiving the effects of the two drugs similarly. Only college students differentiated between drugs, perceiving cocaine as less likely than alcohol to produce drunkenness and more likely to have stimulant and elation/empowerment effects. With age and other expectancies controlled, expectancy of drunkenness was the best predictor of disapproval of alcohol use; attitudes toward cocaine use were unrelated to expectancies but became more negative with age. Drug prevention programs should rest on data regarding children's preexisting beliefs about the consequences of drug use and should help them understand that different drugs (for example, stimulants and depressants) pose different dangers.
