Young adults who do not use tobacco products report higher intentions of using Puff Bar, a leading e-cigarette brand that has a "tobacco-free nicotine" claim, than products with the regular claim of containing nicotine, according to a Rutgers study.

The study, published in the journal Tobacco Control, also found that the claim may reduce young adults' perception that the products might cause health risks and may prompt the use of the Puff Bar brand over other e-cigarette brands and types.
