Visual attention to blu's parody warnings and the FDA's warning on e-cigarette advertisements.

Objectives: In 2017, the e-cigarette brand, blu, released advertisements featuring large, boxed, positively-framed messages. These messages mimicked the format of FDA-mandated warnings that would appear on e-cigarette advertisements in the United States in 2018. We compared attention to blu's parody warnings and FDA-mandated warning appearing on blu advertisements.
