my wife smoked since she was 15 years old, now she is 29. she has been vaping for 1 month now. she complained she still craved a cigarette. i got her that cigarette. she smoked 1/2 of it and said it was one of the most nasty things she's done. she threw it out after smoking 1/2 of it. this is a great thing, she has already lost the smokers cough and i think she is already healthier. she said the vape tastes a whole lot better. she went right back to her riva 510. i am very pleased by the results. she is no longer killing herself, she will live longer and healthier thanks to the e cig.
