Hand pipes are smoking devices used to inhale tobacco, herbs, or other substances. They are typically small, portable, and designed to be held in one hand. Hand pipes come in various shapes, sizes, and materials such as glass, wood, metal, or ceramic. They usually consist of a bowl where the smoking material is placed, a chamber to hold the smoke, and a mouthpiece for inhaling. Hand pipes are popular among smokers for their convenience, ease of use, and portability.
