Hello, Been smoking for 11 years (26 years old + been smoking since 15) Went out and brought an ipv D3 mod and Aspire cleito tank yesterday before class and... yeah, its definitely been my calling. From a guy who smokes a pack a day to go 28hrs and still having a FULL BOX of Newport 100's is really saying something. Getting use to inhaling, been choking like a twisted sick clown, but really prefer this over the cancer sticks.
