Gender and impulsivity differences in licit substance use.

Gender differences in ratings of impulsivity have shown increased impulsivity in men. Research also suggests higher impulsivity is correlated with increased use of alcohol, nicotine, and caffeine. In a large sample of young adults (N = 332), self-report data were collected on licit substance use and impulsivity/nonconformity. Among men, significant differences were found between higher and lower impulsivity groups for alcohol and caffeine use but not for nicotine use. Among women, significant differences were found between higher and lower impulsivity groups for alcohol and nicotine use but not for caffeine use. The data suggest the importance of recognizing gender differences in the relationship between personality factors and licit substance use.
