This is not just for Volcano, which I currently use, but for e-cigs altogether... I ordered mine off the internet 4-1/2 years ago and the day it come in the mail was the last day I smoked a cigarette. Gum, lozenges and patches do everything for the chemical aspect of the addiction, but only e-cigs treat both the chemical as well as the physical aspect of the addiction. There are so many advantages to e-cigs that I could delve in depth on each one, but the bullet points are: Per a doctor, nicotine is as bad for a person as caffeine, With the cost of cigarettes topping $7 a pack, if you only smoked a pack a day, that computes to over $200 a month while e-cigs cost about $40 a month. I can laugh without coughing, enjoy physical activity again, and sing without having to take several breaths to get through a verse. E-cigs are by far the best invention for smokers ever invented. Congratulations to all who quit smoking cigarettes through the use of e-cigs!
