The reasons people use e-cigarettes are shifting: Fewer people are using them to quit smoking, and more people are using them to boost their social image, a new study finds.
The findings could have important implications for public health, as they could help guide initiatives seeking to discourage e-cigarette use, the researchers said.
Although scientists have previously looked at why people choose to use e-cigarettes, the researchers of the new study noted that the surveys used in past research typically limited the participants' responses.
For example, surveys may have included a series of yes-or-no questions, or multiple-choice questions, and didn't allow respondents to answer in their own words.
