Cannabis use and mental health problems
研究大麻使用是否导致心理健康恶化，发现当前使用比过去使用影响更大，且使用频率与心理健康问题概率呈剂量反应关系。
Abstract This paper investigates whether cannabis use leads to worse mental health. To do so, we account for common unobserved factors affecting mental health and cannabis consumption by modeling mental health jointly with the dynamics of cannabis use. Our main finding is that using cannabis increases the likelihood of mental health problems, with current use having a larger effect than past use. The estimates suggest a dose–response relationship between the frequency of recent cannabis use and the probability of currently experiencing a mental health problem.
