Im using 2mg But Im not sure nic is my issue Im use too cigs with certain things, at work Im a Mechanic/Machinist and run the shop when the boss isnt around ( I run around doing like 10 things at once)sometimes its easier to have the cig In my mouth as opposed to the invader (ive tried its heavy) I think its the mental thing pulling me back which is weird because when I started vaping all I wanted too do was vape
