ABSTRACT
Psychoactive substances act on the central nervous system producing changes in mental processes, such as perception, consciousness, cognition or mood and emotions. The present study aims to identify: (i) the most used psychoactive substances, (ii) how psychoactive substances are acquired, (iii) and possible reasons for the use of psychoactive substances amongst university students. A literature search was carried out without language restrictions and included articles published between 2019 and 2020 in journals indexed in the electronic databases of Pubmed and Scielo. The inclusion criteria considered were: (i) original articles, (ii) studies carried out with university students, (iii) providing data on the use of psychoactive substances. 15 studies were included in this review, of which: 4 studies addressed possible reasons that lead to use of psychoactive substances, 10 studies reported usage profile and demographic data, and 1 study addressed how students acquire psychoactive substances. Reasons that led to the consumption of psychoactive substances include: feelings of loneliness after moving away from family; difficulty making new friends; poor academic performance and susceptible environment to acquisition of these substances. In the selected studies, alcohol was identified as the main drug used. In light of the findings reported in this review, new prevention and harm reduction measures can be formulated, based mainly on the reasons that lead to the use of psychoactive drugs, consumption patterns and how the drugs were acquired by university students.
