I haven't had a cigarette in months now. I've completely switched to vapor and love it. I feel a lot better, don't cough in the mornings any more, and my breathing is great now.
I smoked for over 35 years and was up to 3 packs/day.
Today I bought my 8th "mod". It's a monster and I love it.
Here's a photo of it between two other mods that are considered to be large. It's a fracking beast.
