VAPING BEATS STANDARD NRT METHODS - NEW ENGLAND JOURNAL OF MEDICINE
Early in the study, both groups used their treatments nearly every day. Over time, though, a strong difference emerged. Some 40 per cent of smokers in the e-cigarette group were still vaping at one year while only 4 per cent in the NRT group were still using their nicotine replacement product. Among those not smoking at one year, the proportion using e-cigarettes was 80 per cent, and using NRT was 9 per cent.
