I smoked Blue camels, around half a pack a day, but never less and sometimes closer to 1 pack for around 8 years.
I just recieved my Tornado tank this morning, and i feel almost high from my 12-16mg prefilled cartridges(Mid. strength from Totally wicked). The throat-hit is insane and next time i order liquid i will buy som low strength liquids, thats for sure!
...which takes me to my point, i thought i needed around 18 atleast, but man, apparently not!=)
