I smoked for about 35 years and was up to 1-2 packs per day when I discovered e-cigarettes. It took me awhile to find the right combination of equipment, but I was very quickly off of cigarettes completely. I have not smoked a regular cigarette in 4 years. I use 510 based ecigarette batteries and atomizers, with 24mg strength PG/VG juice. I had tried quitting cold turkey a few times throughout my smoking years, with no luck. I do not have the willpower. If e-cigs become unavailable, I believe I will inevitably have to start smoking again. This would be devastating!
