Figure 4

Random-effects meta-analysis of N = 5 studies on anxiety + depression vs. cannabis use/no use. Notes: The forest plot (top) shows that there was an overall positive association between anxiety+depression and cannabis use in N=5 studies (overall mean weighted OR=1.68, 95% CI: 1.17-2.40). The funnel plot (bottom) was symmetrical suggesting that there was little evidence for a publication bias in the current analysis.
