To the Editor Anderson et al¹ claimed that data from 7 states with recreational marijuana laws (RML) supported the hypothesis that teen marijuana use decreased because “it is more difficult for teenagers to obtain marijuana as drug dealers are replaced by licensed dispensaries that require proof of age.”¹ However, their conclusion is erroneous because they do not have data from 7 states following the initiation of legal commercial sales of recreational marijuana by these age-verifying stores. In fact, they only have data from 2 states following legal sales,² and neither state saw teen use drop more than the national average.

挑战青少年大麻使用与大麻法律的关联

致编者Anderson等人¹声称，来自具有娱乐性大麻法律（RML）的7个州的数据支持了青少年大麻使用量减少的假设，因为“由于由需要证明的毒品交易所代替，毒品贩子使青少年更难以获得大麻年龄。” ¹但是，他们的结论是错误的，因为在这些年龄验证商店启动休闲大麻的合法商业销售之后，他们没有来自7个州的数据。实际上，他们只有来自合法销售后的2个州的数据，²而且没有哪个州的青少年使用率下降幅度超过了全国平均水平。
