Plunk AD, et al. – Via analyzing data from 38 states—including 4 with cannabis legalization policies and 7 with cannabis decriminalization policies—researchers investigated whether arrests of youths for possession of cannabis change when cannabis policy focuses on adults. They found that arrest rates of youths significantly decreased in states that decriminalized cannabis possession for everyone but did not decrease in states that legalized adult use. Therefore, the authors suggested that state decriminalization policies should take the additional step to explicitly specify when adolescents/young adults may be arrested for the possession of small amounts of cannabis in order to address this problem.
