Error in Methods Section and Figure

In the Original Investigation titled “Assessment of Exposure to High-Performing Schools and Risk of Adolescent Substance Use: A Natural Experiment,” there were errors in the Methods section and Figure 1. In the Methods section, the number of potential participants identified should be 1995 instead of 1996, and the number of ineligible participants should be 486 instead of 487. Likewise, in Figure 1, the total number of potential participants should be 1995, and the number of ineligible patients should be 486. In addition, the number of individuals unable to be contacted or had moved should be 319 rather than 320. Under intervention baseline, the number of individuals who were unable to be reached and individuals who refused were switched. This article was corrected online.
