[Perceived norms among Honduran university students about peers and tobacco, alcohol, marijuana and cocaine use].

The purpose of this study was to assess the difference between perceived norms and peers' drug use among sophomore and junior university students (from the field of education) aged 18 to 24 years. The Social Norms Theory was used as the theoretical framework. In total, 286 students participated in the study, 67% of which reported having consumed alcohol at least once in a lifetime and 28% stated being daily users. Students perceived that 62% of their peers used tobacco and 63% used alcohol. The perceived norm for drug use was slightly higher in women than in men. In conclusion, there is an overestimation between the perceived norm and use of alcohol, tobacco, marijuana and cocaine.
