after you take a big drag (dont inhale it, keep it in your mouth), drop your jaw as low as it can go, and tighten your lips and make them into an O. dont exhale, but instead, slightly close your jaw (but not all the way). the smaller volume of your mouth causes the smoke to leave your mouth in a ring. it might sound complicated, but keep trying it, itll get really easy, and tell us when youve got it down. happy tokin'!
