Blunts are often made with blunt wraps: tobacco-based wraps — often flavored — that are related to the wraps used on a blunt cigar and are often used to roll cannabis Blunts can also now be rolled with Hemp wraps that do not contain Nicotine. There are several types available in varying flavors as an alternative to using a cigar wrapper, for those people who don't desire the nicotine. Reusable materials Pipe or bowl Pipes made for smoking cannabis, sometimes called pieces or bowls, are made of a variety of materials, including metal fittings, ceramic, borosilicate glass, stone, wood, bamboo among other materials. Subtypes include one-hitters, bubblers, chillums, glass blunts, corn cob pipes, and standard hand pipes. Pipes vary greatly in shape and materials, and most are handmade. The common thread between them is having a narrow screened receptacle ("bowl"), a "stem" (which may be a long flexible tube as on hookahs and vaporizers), and a "mouthpiece". The smoking material is placed in the receptacle and affected with a heat source while air is drawn through the bowl and stem to the user. Blown-glass pipes and bongs are often intricately and colorfully designed. In India and Jamaica, the most commonly used pipe is the chillum.; in the UAE, midwakh; in Morocco, sebsi''. A one-hitter is a device used for a single serving (usually 25 mg). Chalice is a cannabis smoking pipe used most often by members of the Jamaican Rastafari movement. Bubbler A bubbler is a mix of a bong and a pipe. They tend to look like small bongs and are another way to smoke cannabis. A bubbler contains a chamber for water, commonly with a down stem directly connected to the bowl of the piece. A bubbler normally has a dedicated carburetor, a hole which is usually covered with the finger then opened for mixing clean air with the smoke to make inhaling easier. Because of the carburetor there is no need to pull the stem as you would with a bong. Bong A bong is similar to a pipe, only it has a water-chamber through which cannabis smoke passes prior to inhalation. Users fill the bong with water, sometimes also adding ice in order to cool the smoke. This cooling effect reduces the discomfort caused by the heat of the smoke. The bowl and stem assembly of most bongs is removed briefly after the cannabis is burned,
