In the Original Investigation entitled “Cannabinoids for Medical Use: a Systematic Review and Meta-analysis” published in the June 23, 2015, issue of JAMA,1 the axis labels for Figure 4 were mislabeled. The label on the left should read: “More Adverse Events With Placebo” and the label on the right should read: “More Adverse Events With Cannabinoid.” This article was corrected online.
