to let smoke out slow to bull up your nose or blow smokerings or whatever, you just inhale into your mouth and then open your mouth and 'push' the smoke out. you can use your face muscles to push the smoke out sorta like you are trying to make a fish face... or breathe it straight into your lungs and then exhale really, really slow.
okay im shitty for directions but thats the best i can give ya for now, haha.
