I smoked for over 20 years at 2 packs a day. I quit the day I tasted ejuice in a Vaporizer. I tried the ecigs but they were not good enough. My husband also quit smoking by vaping. I just got my Mother switched from smoking for over 50 years. I can climb stairs without losing my breath and I feel better than ever. I hear so many others who feel better yet nobody wants to admit in the media or the FDA that ecigs/vaping is safer. Facts are facts.
