People who vape have lower levels of exposure to a tobacco-related carcinogen than cigarette smokers, according to a new study of urinary biomarkers.
Lower concentrations of a carcinogen metabolite in urine suggest that "switching completely from combustible cigarettes to e-cigarettes may provide significant health benefits," said Hongying Daisy Dai, PhD, professor and associate dean of research in the College of Public Health at the University of Nebraska Medical Center in Omaha, who is the corresponding author of the study.
