About The Study: In this pooled analysis involving firearm laws and firearm-related deaths from 2000 to 2019 in the 48 contiguous states, a permit requirement for purchasing all firearms had an interstate association with decreased total firearm-related deaths and homicide, whereas the prohibition of firearm possession for individuals who have committed a violent misdemeanor had an interstate association with decreased firearm suicide. These findings suggest that synergic legislative action to implement firearm laws in proximate states may help prevent firearm-related deaths.
