I smoked for over 50 yrs. I have 2 months on the e-cig. I am totally tobacco free. I wanted to quit smoking cigarettes. I was never successful. I had tried every market product, even under Doctors care., Chantix made me very sick. Nothing worked for me. I feel in control with the e-cig. I am reducing my nicotine intake on a gradual basis. This eliminates all the irritability with going cold turkey. A plus in every area of my life, no cigarette butts, no smells, no fire, (lighters, etc.). My local store collects the used cartridges for recycle thru the sales rep. The only negative I can comment on is some times I lose my e-cig and have to get another. I use a rechargeable so will just get another kit. Then the one I lost will turn up. Ha! The e-cig has changed my life for the better and my families. I have NO DESIRE FOR reg tobacco cigarettes. I am done with them.
