A study, published in Cancer Epidemiology, Biomarkers & Prevention, examined the use of e-cigarettes as well as changes in smoking behaviors.
Researchers studied 68 smokers, of which 46 were randomized into a group that could use e-cigarettes as they wished and 22 were randomized into a control group. The study subjects were followed for four months. The e-cigarette group received a vaping device with either high or low doses of nicotine.
The study shows that smokers who use e-cigarettes tend to smoke less and have more quitting attempts, as compared to the control group. Additionally, smokers who were given e-cigarettes without any instructions or requirements for use, tended to take up vaping and many purchased their own e-cigarettes.
The study also shows those using e-cigarettes smoked an average of 37 percent fewer cigarettes than the control group through the study period.
The study was funded by the National Institutes of Health.
