E-cigarette users are possibly putting themselves at risk for developing heart disease, lung and bladder cancers, according to a new report. The study, conducted by researchers from the New York University School of Medicine, exposed mice to e-cigarette smoke (ECS) for 12 weeks at a dose and duration equivalent to light e-cigarette smoking for 10 years in humans. Another study, published August 2017, compared cancer potencies of e-cigarettes and tobacco smoke and found most ECS to have a cancer risk of less than 1 per cent of that from smoking. Many are worried that the mild flavour of ECS will hook young people on nicotine, encouraging teenagers to smoke tobacco in the future. Tumors can’t develop in 12 weeks-the length of the study-and if tobacco smoke-induced cancer is indeed a model for e-cigarette smoking-induced cancer, then meaningful human evidence won’t be available for at least another decade.
