I do well on 6mg and don't feel bad if I vape a lot at times...maybe you need a longer draw..
Maybe.
I also don't inhale. Do you?
And I don't blow the smoke out through my nose at all...that just feels weird to me.
So i just take about a 6 second draw, hold it in my mouth, and exhale.
I read on here that inhaling with e cigarettes is different as the particles aren't as small as in real cigarette smoke...so they won't get absorbed by the lungs as much, so a lung hit won't do as much with an e cigarette.
