Teenagers who use electronic cigarettes are exposed to cancer-causing chemicals found in tobacco even when the e-cigarettes don’t contain nicotine, according to a new study.
Researchers at University of California San Francisco analyzed urine and saliva from 67 teens who used e-cigarettes and found they had been exposed to some of the same chemicals in tobacco that cause cancer.
Under-18s are almost three times more likely to use e-cigarettes than adults, according to the most recent data from the Centers for Disease Control and Prevention.
