To smoke a popper, you pull very slowly, making the smoke come out very thick. Another method of packing a popper is to use a normal down-stem and bowl, and squeeze the tobacco out of the end of the cigarette into your bowl, then packing the weed on top. The cigarette will get stuck, then you pack however much weed you want on top of it. Common methods of packing poppers include cutting part of a cigarette off (about a 1/4 centimeter or more) and putting it in a metal tube, known as the popper piece or popper cannon, which you will use as a replacement for your downstem. Less commonly referred to as a yacht, a popper is a method in smoking marijuana in which the smoker packs tobacco under his weed.
