Reactions to Warnings on Hookah Ads

Participants will view 24 ads with and without health warnings. Additionally, 16 control non-tobacco ads matched for graphical content, presence of text, people, and other factors will be randomly distributed among these ads.

Participants will view at random 24 ads twice, each ad will have a different health warning chosen at random with the caveat that each health warning will be seen 3 times. The 16 control ads will have text disclaimers to control for physical features of the ads.

This arm is identical to the text only intervention except a graphic will be added to the health warning. Thus, each ad will be seen twice; the text + graphic warnings will be seen three times. The 16 control ads will have text disclaimers and logos or other images to control for physical features of ads.
