I don't know why, but from my very start I inhaled into my mouth and then out my nose. I don't really do lung.
I know my tastebuds get the flavor and my nose gets the smell. As to the nicotine, the vaper clings to my nose hairs or something like that. Anyway, I don't get that throat burn. Not really sure how much I would like it or not like it. It just seemed natural the way I do it.
Good luck exploring!
