Well, I can't do the direct to lung inhale easily for some reason My body just doesn't seem to want to co-operate. I've tried it but didn't really get the hang of it or enjoy doing it.
I inhale vapour into my mouth, savour the taste, open my mouth slightly and take a breath so vapour and air go into my lungs. I find this pretty satisfying, half the pleasure is feeling the vapour in my mouth.
There might be a difference with absorption of nicotine from vapour that could be taken into account too. Like cigars and pipe tobacco which aren't supposed to be inhaled, our vapour has high pH. That suggests there is better absorption through the mucus membrane of the mouth and throat. Cigarette smoke is more acidic which is said to be better for lung absorption.
