Traffic fatalities in Colorado and Washington State before implementation of recreational cannabis laws (RCLs) are best reproduced by a combination of the states listed above (eg, for Washington State, a combination of California, Connecticut, Delaware, New Jersey, and Rhode Island, with New Jersey having the strongest influence on combined estimates). Forty-two states were used in the pool of controls. States implementing RCLs during the study period (Alaska, Massachusetts, Maine, Nevada, Oregon, Colorado, and Washington) and states outside the contiguous 48-state region (Alaska and Hawaii) were not included.
