The study included more than 1,400 students, aged 18 to 23, at four colleges/universities in upstate New York who took part in an online survey.
More than 95% of the respondents knew about e-cigarettes, and nearly 30% said they had tried e-cigarettes, the survey found. Those most likely to report current or previous use of e-cigarettes included: males, younger students, whites, those with average or below average school grades, and those who have ever smoked or tried cigarettes.
The survey results also showed that students who considered e-cigarettes to be less harmful than traditional tobacco products were also more likely to use e-cigarettes.
Among e-cigarette users, 87% said they used another nicotine product before trying e-cigarettes, and nearly 35% said they used tobacco products other than cigarettes, and/or alcohol (about 65%) in the past 30 days. In addition, nearly 36% said they used marijuana in the past year.
The study was published recently in the journal Drug and Alcohol Dependence.
