I am going to college for singing and often times I can't afford to take full on hits because of my lungs. Often times we will shotgun through kissing when I need to conserve, it pulls the heat from the hit and it isn't as strong.

When I'm with friends I either use a toilet paper roll or lock pinky fingers then close your fists loosely and breath through the tunnle created by your closed hands.

It's sometimes cool to shotgun through the nose. If you're with someone you don't mind putting their mouth over your nose you can breath through the nose. :thumbsup:
