Heated Tobacco Product Awareness, Use, and Perceptions in a Sample of Young Adults in the United States.

In Fall 2019, as IQOS was launching in the US, there were relatively low rates of awareness, use, and use intentions in this sample of young adults with high proportions of other tobacco use. However, this sample reported relatively positive perceptions of HTPs with regard to potential addiction and harm, as well as social acceptability. They also reported accessing HTPs via various channels, underscoring how pervasive the availability to HTPs already has become and may increasingly become. Moreover, certain subgroups (ie, other tobacco users, men) are particularly likely to use HTPs.
