(NewsNation) — The legalization of marijuana is linked to a rise in heart-related hospitalizations in the United States, a new study finds.
该研究发表在《BMJ Open》上，考察了西部各州通过投票措施将大麻合法化后的住院率。
The research, published in BMJ Open, examined hospitalization rates following ballot measures legalizing cannabis in Western states.
