frozen mugs are real cool.freeze a glass mug get a straw joint in one end slowly shotgun into the botom of the mug.when the mug is 1/4 to 1/2 way full of smoke tilt glass to lips and the smoke will actually go down without trying to inhale.there is no need to try to hold it in either it will stick to your lungs and very little smoke will comeout.be warned this is not for rookies.on top of coughing your ass off it really fucks you up.
