Early drinkers tend to be heavy drinkers for life. In contrast, those who begin drinking after age 21 have low rates of heavy drinking. This is due to the relative societal approval and acceptance of drug use in the form of alcohol consumption as compared to illicit drug use. Several studies indicate that students have definite perceptions about alcohol related behaviors and attitudes of other students, which in-turn influences their own pattern of use. Cultural factors are exploited to influence alcohol use patterns, primarily to promote sales.
