Interventions

Type	Name	Description
BEHAVIORAL	Ads Only	Participants will view 2 ads without replacement.
BEHAVIORAL	Ads with text-only health warning labels (HWLs)	Participants will view HWLs in one of four domains: long- and short-term health events, toxicants, and addiction; participants viewed two HWLs within each domain - there were two HWLs per domain. The text HWLs were placed randomly on two ads out of the possible four ad themes without replacement. Thus, participants viewed two HWLs within the same domain, with each warning being placed on a different ad.
BEHAVIORAL	Ads with text + graphic health warning labels (HWLs)	Participants will view HWLs in one of four domains: long- and short-term health events, toxicants, and addiction; participants viewed two HWLs within each domain - there were two HWLs per domain. The text + graphic HWLs were placed randomly on two ads out of the possible four ad themes without replacement. Thus, participants viewed two HWLs within the same domain, with each warning being placed on a different ad.
