I had smoked for 9 years untill i started using an e-cigarette. First i used both the e-cig in moderation to cigarettes untill i had decided to stop smoking cigarettes alltogether. I found that after using the e-cig I did not have any cravings to cigarettes at all. Also that my clothes, breath, hair, and car did not stink anymore also. After a month or so I noticed that my blood pressure started going back to normal. (I had pre-hypertension). Also I noticed that i had more stamina and my shortness of breath and coughing was gone.
