A chillum is one of the easiest pipes you will use. First, grind your dry herbs. Then, lightly pack the dry herbs into the front-facing bowl of the chillum pipe. Then, apply a flame to the dry herbs and slowly draw in the smoke. When the bowl is depleted, dump out the ashes and safely store the chillum. Other specific chillum pipes may have other features, like a carb hole, but these general steps are a good place to start when using a chillum for the first time.
