Protocol for creating a dataset of U.S. state alcohol-related firearm laws 2000-2022

Firearms are a major source of preventable morbidity and mortality in the United States, contributing to over 48,000 deaths in 2022 and generating societal costs in excess of $500 billion. A body of work has examined the relationship between US state level firearm laws and health outcomes, generally finding that some firearm regulations are associated with lower firearm-related mortality. Alcohol has been identified as an additional risk factor for both homicides and suicide and stronger state alcohol laws have been associated with lower rates of suicide. To date, there are no empirical studies that have investigated the impact of laws over a long period of time that target the intersection of alcohol and firearm. One reason for this may be because there is no existing dataset that includes the range of these state laws over time. This study describes the protocol for collecting, coding and operationalizing these legal data.
