Teenagers who vape often could be at a higher risk of exposure to toxic metals, potentially harming brain or organ development, a study has suggested.
Sweet e-cigarette flavours could also pose additional risks, according to researchers. US academics used responses from part of the Population Assessment of Tobacco and Health (PATH) study, which included American teenagers aged between 13 and 17.
Some 200 teenagers who vaped were included in the analysis, which has been published in Tobacco Control.
