ABSTRACT
BACKGROUND: Psychoactive substance use among adolescents has been identified as an important health issue in Nepal. Therefore, this study examined the psychoactive substance use and factors associated with its use among adolescent students in the Rupandehi district of Nepal. METHODS: A school-based cross-sectional study was conducted from December 2017 to July 2018 with 460 school students aged between 15 to 19 years across sampled public and private schools in the Rupandehi district of Nepal. Structured interview schedule was used to collect information on psychoactive substance use. The generalized estimating equation was used to identify the factors associated with the use of psychoactive substances. RESULTS: Over a quarter (27.4%) of school-going adolescents used at least one type of psychoactive substance. Commonly used psychoactive substance included tobacco products (59.3%) followed by cannabis (55.6%), marijuana (35.8%), hashish (23.5%), alcohol (22.2%), heroin (18.5%), nitrogen tablets (14.8%), sulfa (13.6%) and opium (13.6%), respectively. Being male (AOR=2.0, 95% CI: 1.19-3.36), having peers (AOR=1.8, 95% CI: 1.13-3.03) or family members (AOR=2.2, 95% CI: 1.40-3.54) that used psychoactive substances and father's education level (AOR=2.5, 95% CI: 1.05-5.78) were significantly associated with the psychoactive substance use. CONCLUSIONS: This study identified that over a quarter of school-going adolescents reported the use of at least one illegal psychoactive substance. This study provided details on the extent of behaviours, and can be used to develop a comprehensive prevention and control program. Such programs should address the socio-cultural factors that enable substance use and address gaps in knowledge to prevent and control of psychoactive substance use.
