Background - The Gateway Hypothesis argues that there is a sequence in the use of various drugs and that the use of one substance serves as a gateway for the use of another substance. The aim of this thesis was to examine various aspects of the Gateway Hypothesis using data from the Avon Longitudinal Study of Parents and Children (ALSPAC) (unless stated otherwise). Individual summaries of the multiple methodologies applied are described below. Systematic Review and Meta-Analysis - Aim: To conduct a systematic review of current Gateway Hypothesis literature. Methods: Longitudinal studies examining empirical data were selected and study characteristics extracted. Results were combined using metaanalysis. Results: Nineteen articles from 14 studies were included reporting 17 drug exposure and outcome combinations. Meta-analysis provided evidence for association of tobacco use (OR=2.60, 95% CI 1.39-4.85, p=0.003) and alcohol use (OR=1.56, 95% CI 1.16-2.10, p=0.003) with cannabis use, and between cannabis use and other illicit drug use (OR=2.79, 95% CI 2.01-3.87, p
