Risk and protective factors for cannabis use among young people - a population based survey

Abstract

Abstract Background Cannabis is the most commonly used illicit substance in Ireland and globally, with its use most likely to occur in adolescence when the developing brain is more vulnerable to cannabis-related harm. This study aims to ascertain the prevalence of and determine the risk and protective factors for cannabis use among adolescents in the North East of Ireland. Methods This study is a cross-sectional, secondary analysis of the 2021 Planet Youth survey. The population comprised a sample of 4404 adolescents aged 15-16 in Cavan, Monaghan and North Dublin. The outcome of interest was cannabis use in the last 30 days. Independent variables were selected a priori following a literature review. Associations between cannabis use and the independent variables were explored using logistic regression. Results The prevalence of current cannabis use among study participants was 7.3%. The odds of cannabis use were higher among current alcohol users (aOR 2.68, CI 1.79-4.02), smokers (aOR 3.17, CI 2.18-4.60), e-cigarette users (aOR 2.72, CI 1.87-3.96), adolescents who did not perceive its use as harmful (aOR 2.24, CI 1.51-3.32), felt their parents were not against cannabis (aOR 3.71, CI 2.43-5.66), had cannabis-using peers (aOR 9.81, CI 5.76-16.71) or felt peer pressure to use cannabis (aOR 1.91, CI 1.09-3.33). Low parental supervision was associated with higher odds of cannabis use. There was no association between gender and cannabis use. Conclusions This study identified five risk factors and three protective factors associated with cannabis use which can be targeted by policymakers when designing drug prevention strategies.
