Tell you what, a high nic level and I am bonked, I may be more into flavor because I don't like the dizzy feeling. Didn't realize I was such a light weight. Lol I even smoked Kool Regulars from time to time and they are non-filtered!!! I read a post somewhere, guy said ten drags on the ecig and then if that wasn't enough then he would have the analog but never did... What is your highest nic level cart/juice V??
