Hoping you can tell me, is tobacco-free and nicotine-free e-cigarette safe to quit smoking with?

Not nicotine free: E-cigarettes are not nicotine free ; not advised to quit. They are not regulated, we don't know much about the levels of nicotine and other chemicals, and there's no research showing they help smokers quit. More info found at http://smokefree.Gov/e-cigarettes the best ways to quit are to use coaching and approved treatments such as nicotine patch, gum or lozenge or prescription medications.
