Eve, been vaping now for 3 years, I stopped smoking mothers day in 2014. I found out that the carcinogens in regular cigs were the cause of affecting my PTSD and causing me to explode violently. Luckily I never hurt anyone or my family but it scared the hell out of me when I realized it, I drop cigs right then and started vaping cigalikes, moved up to the ego pens, and from there I have been using my IPV2 black edition with a Lemo II tank. Since then my wife said I am a new man.
