Effects of state education requirements for substance use prevention
利用1976-2010年超百万青少年的数据，研究发现州法律要求学生接受酒精、烟草等药物教育，使高中生近期饮酒和吸大麻的比例下降1.6-2.8个百分点，约占同期总降幅的8-10%。
We provide the first evidence on the effects of state laws requiring students to receive education about alcohol, tobacco, and other drugs using data on over a million youths from the 1976-2010 Monitoring the Future study. In difference-in-differences and event-study models, we find robust evidence that these laws significantly reduced recent alcohol and marijuana use among high school seniors by 1.6-2.8 percentage points, or about 8-10% of the overall decline over this period. Our results suggest that information interventions can reduce youth substance use.
