Marijuana Legalization and Suicides Among Older Adults
研究发现，美国老年人自杀率上升的同时，医用和娱乐用大麻合法化后，娱乐性大麻店的开业降低了老年人自杀率，尤其对低教育水平的白人群体影响显著。
ABSTRACT Suicide rates among older adults have been rising over time in the United States. At the same time, more individuals have been suffering with chronic pain and illness, which are often underlying risk factors for suicide. As self‐medication with marijuana has become common, we ask whether access to legal marijuana for medical and recreational purposes reduces suicide rates among older individuals. We find that suicide rates among older age groups decline following the opening of recreational marijuana dispensaries, especially among older Whites, and middle‐aged White males and females with low levels of education.
