  1. Internet search rates were obtained using Google Trends for 2016 and these rates were observed for associations to the National Survey on Drug Use and Health for 2016–17 statistics (National Institute on Drug Abuse 2019) and access to legal cannabis grades using a linear regression for the beta coefficient values in Stata 15.1. State-Level Drug Use Characteristics were from the National Survey on Drug Use and Health (National Institute on Drug Abuse 2019). Access to legal cannabis was based upon the American’s for Safe Access state cannabis grade (Reports [Internet] 2020)
