i used to smoke close to two packs a day, smoked for 3 years or so. i first tried vaping because alot of my friends switched to vaping so, so did i. i immeidatly swicthed like 2 years ago i started with an ego and a cartomizer tank. i liked that i got to choose from unlimited ammount of flavors, and strengths. now i vape on a 150w box mod and an RDA. its great. if you take this from me i will definately go back to smoking those coffin fusez. my family is a lot happier with my truck not smelling like smoke.
