我们研究大麻使用对性活动，避孕和出生计数造成的行为变化，通过应用差异中的差异方法，利用各州之间引入医用大麻法律（MML）的时间变化。我们发现MML会导致性活动增加、以发生性行为为条件的避孕药具使用减少以及出生人数增加。也有暗示性的证据表明，在国家一年淋病率暂时增加。这些变化可能归因于行为反应，包括增加对性接触的即时享乐效应的关注，增加性频率，以及延迟贴现和忽视与性相关的未来成本。我们在生育方面的发现表明，行为因素可以抵消大麻使用导致的生理变化，这些变化往往会降低生育能力。我们的发现对一系列广泛的测试都是可靠的。(C)2019年爱思唯尔出版
We study the behavioral changes caused by marijuana use on sexual activity, contraception, and birth counts by applying a differences-in-differences approach that exploits the variation in timing of the introduction of medical marijuana laws (MMLs) among states. We find that MMLs cause an increase in sexual activity, a reduction in contraceptive use conditional on having sex, and an increase in number of births. There is also suggestive evidence on temporary increases in the state-year gonorrhea rate. These changes may be attributed to behavioral responses including increased attention to the immediate hedonic effects of sexual contact, increased sexual frequency, as well as delayed discounting and ignoring the future costs associated with sex. Our findings on births suggest that behavioral factors can counteract the physiological changes from marijuana use that tend to decrease fertility. Our findings are robust to a broad set of tests.
