I've never done that with a joint, but using a blunt works pretty well.

We've always called it shotgunning. What's fun is to take a shotgun, flip the blunt around, and then before exhaling, give a shotgun back.

You can go back and forth on a blunt and watch the smoke get darker and darker and darker.
soteksguard Reviewed by soteksguard on . blowback question Hey sup, So I know a blowback is when you put a lit joint backwards into your mouth and blow un-inhaled smoke into the other person's mouth. But suppose you take a hit from a pipe and blow the smoke you took into yourself into your partner's mouth and she inhales it fast. Would this get her blazed or is it just a waste. Also, is this also called a blowback. Thx a lot, peace. Rating: 5
