A dab pen, also known as a wax pen or vape pen, is a portable and discreet device used for vaporizing cannabis concentrates such as wax, shatter, or oil. It typically consists of a battery, a heating element (atomizer or coil), and a mouthpiece. Users can load a small amount of concentrate onto the heating element, which then vaporizes the material into an inhalable vapor. Dab pens are popular among cannabis enthusiasts for their convenience, ease of use, and ability to provide potent and flavorful vapor without the need for a traditional dab rig or smoking device.
