A Bong is a glass water pipe used for the consumption of cannabis, tobacco, or other herbals. Suction is created when a carb is closed by a slide which is removed when the user is ready to inhale the smoke. The word is derived from the Thai word baung (บ้อง), which refers to a bamboo pipe used for smoking marijuana. The use of bongs date all the way back to the 16th century. It was introduced to China through the silk road and remains a culturally significant pipe for those who smoke weed.
