This report highlights findings from the Youth19 Rangatahi Smart Survey (Youth19) about smoking, vaping, alcohol use, and use of marijuana and other drugs. It is designed to be read with the Youth19 Rangatahi Smart Survey, Initial Findings: Introduction and Methods report, which explains how the survey was conducted, who was included and how to interpret the results. This document and other Youth19 outputs are available at

As part of Youth19, secondary school students answered questions about their substance use. We present an overview of these findings and changes over time, first for the total population (all students combined) and then for Māori, Pacific, Asian, and Pākehā and other European groups. Finally, we outline opportunities for supporting students who face challenges with substance use.
