Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Hookah Tobacco Smokers; Young adults, ages 18-34, who smoke hookah tobacco	Behavioral: Control; 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.; Behavioral: Text Only; 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.; Behavioral: Text + Graphic; 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.
Active Comparator: Open to Smoking Hookah Tobacco; Young adults, ages 18-34, who do not smoke hookah tobacco but are open to trying	Behavioral: Control; 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.; Behavioral: Text Only; 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.; Behavioral: Text + Graphic; 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.
