I think I know why you cough like a rookie sometimes. It is might not be the girly lungs, but the fact you don't inhale deep enough to get past your throat. Maybe a tweek in your technique where you don't let that smoke escape and you totally bomb it in a huge breath right into your lungs and get through your throat will do it. More absorption in your lungs for high, and less irritation of the throat and larynx.
