A large-scale US review has revealed an increased risk of visual impairment among users of e-cigarettes (vapers).
Led by Dr Abhinav Golla, from the University of California in Los Angeles, the study of nearly 1.2 million over-18s found that those who were current e-cigarette users had a 34% higher risk of being visually impaired, while former vapers had a 14% higher risk of visual impairment, when compared with those who had never vaped.
Researchers said they adjusted for multiple factors that included tobacco cigarette use, age, sex, race/ethnicity, marital status, education, employment status, family income and heavy use of alcohol, but further study of vaping alone is warranted.
