I quit by vaping. For a while (~6 months), I was just happy that my smoking had reduced from a whole pack to 2-3 cigarettes per day. I used the e-cigarette indoors, but wanted a REAL cigarette while walking to the subway or the store. Then, at a certain point, I just didn't want a cigarette anymore. I can't explain it. Gone. No craving. Now, when I pass someone smoking it smells repulsive. I still vape. I know that every smoker is different, but this worked for me. I'm sure that e-cigarettes are not 100% safe (nothing is), but I know that they are significantly safer than cigarettes.
Has anyone else here tried vaping to quit?
