I go through about 100 ml week of 3mg liquid, about 15 ML a day. Is this average or above norm? When I first switched from smoking to vaping, I was only using about 2 ml a day but it was 45mg in a low vapor device. As I lowered the MG on nic, the ml used increased. Still less nicotine per day though than when I started. Okay so how much are you going through in a day or week everyone?
