exhale

For one inhale do you have one exhale? I feel like that should be the case but with weed and just cigarettes too I inhale, exhale as much as I can then have to inhale, exhale repeat a few times until all the smoke is gone out my lungs. I doesn't hurt or feel uncomfortable or everything but I can't remember if I always had to do this.

Can't tell if I'm really high and being retarded or something doesn't add up lol
