I started using e-cigarettes a week ago today. My wife has been using them for about 2 months and I decided to give them a try. We use the Green Smoke with the battery and disposable cartomizers. I have been reading through the various forums and I am really surprised how big of a deal this e-cigarette thing is. I had no idea of the many different types. I thought they were all like what I have and the disposable ones since that's all I see in my area. Well I guess I can learn all there is to know about e-cigarettes here.
