Not really. 12mg is a good start. It's 12mg/ml and u won't vape 1ml (12mg) in a matter of 5 mins like u would an analog.
Most locals here vape at 12mg. Some go as high as 18-24.
Btw, e amt of nicotine vaporized might not be 12mg, could be much lesser, unless u drink it ir rub it on yr skin like u would a patch.
