School-type differences in e-cigarette use and its correlates among Chinese adolescents

“…Our finding that, regardless of school type, the association between tobacco use and e-cigarette use, as well as morning craving, is consistent with existing findings that e-cigarette use was associated with morning smoking urge 20 and ever tobacco use 11,20 .

Patterns of awareness and use of electronic cigarettes in Mexico, a middle-income country that bans them: Results from a 2016 national survey

Indeed, a recent longitudinal study of Mexican adolescents found similar results; 19 however, more research is sorely needed to better understand the patterns of use and potential public health impact of e-cigarettes in low- and middle-income countries (LMICs).…”
