Well, what are you smoking out of?
A Joint: Suck it into the back of your throat a big hit or a little one, then breathe it fast and hard through yoru MOUTH to the lungs, not NOSE to lungs. Then hold it in as long as you can (max 7 seconds) if you want.

Bong/Water pipe: Draw it directly into your lungs and try to push as smoke as you can into your lungs and hold it in.

Pipe: Suck it into your mouth and back throat or directly into your lungs if you can handle it and hold it in.
