“…To assess participants’ awareness of FDA’s authority to regulate tobacco products, we adapted a measure from the 2015 Health Information National Trends Survey (HINTS) ( Peterson et al, 2019 , National Institutes of Health, 2015 ) that asked participants, “Who do you believe regulates tobacco products in the U.S.?” Participants selected all who they thought applied from a list of six entities (Centers for Disease Control and Prevention, Federal Trade Commission, FDA, National Institutes of Health, Surgeon General, and tobacco industry/companies) or selected “None of the above.” We also asked participants, “Has the government put rules in place designed to make tobacco products less harmful?” ( Fix et al, 2011 ) Participants could select “yes,” “no,” or “I don’t know”.…”
