The pipe is an ancient piece of smoking technology, dating back thousands of years. It’s a primitive smoking tool with a bowl and a reservoir leading from the cavity to the user’s mouth. Some pipes are more advanced and have a hole in the side that allows for air intake, this hole on the side is called a carb. Covering the carb allows a hit build up in the hollow of the pipe. Releasing the carb pushes all the smoke at once to the user as opposed to a long drag.
