In this issue of JAMA Pediatrics, a study by Plunk et al1 using evidence from 4 states that legalized cannabis and 7 states that decriminalized cannabis found that legalization of cannabis significantly reduces arrests for possession of cannabis for adults but not for minors. In contrast, decriminalization policies lead to significantly lower rates of arrest for possession of cannabis (on the order of –75%) for both age groups. Although this result is perhaps unsurprising, it stands in contrast to prior work.2
