Ok, first of all. The bowl isn't just the place in a pipe or a name in a pipe. Its mainly reffered to as the amount of weed put into the smoking device. Some people roll there joints with 1 bowl and others use alot more, depending on paper and amount of weed. Bowls Vary for 4 dollars each to over 10 dollars. On average the amount is 5 though. If the bowl your buying is 1 dollar, its either shit or your dealer is high/generous.
