The primer puff really becomes second nature. I do a tiny puff, then another...when it feels warm on my tongue I do a nice long drag,
I did the same thing when I used to smoke analogs,
If they sat for a moment without a drag, I just didn't get the warmth and hit I wanted so I did the little 'primer' puff first so as not to fill my mouth and lungs with a mix of mostly cool air,
