Cross sectional study that aims to understand the patterns of polydrugs use and its gender, social and legal implications among undergraduate students. 275 undergraduate students from the Faculty of Health Sciences from one university in Santo André, Brazil, participated in the study. The simultaneous polydrug use was detected in 27.9% of the sample. Combinations: alcohol + cannabis; alcohol + prescription drugs; alcohol + tobacco + cannabis; tobacco + cannabis; and tobacco + prescription drugs. Reasons: To help relaxing, to lose inhibitions, to help staying awake, to help on doing something upsetting, and to improve the effect of other substances. There was no observed association between legal and social circumstances, men used more poly consumption than women, and religion represented a protective factor to simultaneous polydrug use, which was lower than described in the literature. Considering that subjects in the represent future health care professionals, institutional policies should be discussed in order to reduce exposure and vulnerability to these substances.
