To the Editor: The Commentary by Dr Katz1 considered structural interventions to address chronic health problems. In discussing the cost of such interventions, Katz wrote “ . . . structural interventions that require only changes in policies (eg, removal of vending machines) or enactment of laws (eg, tobacco bans) may cost little to enact.” However, available literature suggests otherwise.
