A bong is a device used to smoke cannabis. It is typically made of glass or acrylic and consists of a bowl, a stem, and a base. The bowl is where the cannabis is placed, the stem is where the smoke travels, and the base is where the water is placed. When you inhale from a bong, the smoke is cooled and filtered by the water, making it smoother and less harsh on the lungs.
Bongs have been used for centuries to smoke cannabis and other herbs. They are a popular choice among cannabis users because they provide a smooth and flavorful smoking experience. Bongs are also relatively easy to make at home, which makes them a great option for those who want to save money or who want to customize their smoking experience.
