By now it is hard to ignore the studied and reported health benefits for smokers who switch to e-cigarettes. Study after study has concluded that using e-cigarettes, like Juul, is eminently safer than smoking cigarettes since they deliver nicotine — what smokers are after — while eliminating 95 percent of the harm of smoking regular cigarettes. New research also finds that “switching entirely to Juul reduced smokers’ exposure to biomarkers, or signals of exposure to cigarette smoking, 99.6 percent as much as abstaining entirely from cigarettes.”
