Gravity bong

As the water flows out of the container, air is forced through the bowl and causes the substance to burn and accumulate smoke in the bong.

While lighting the bowl with (preferably) a lighter or match, the bottle is gradually lifted until it is about to come out of the water or when the substance ceases burning.

[4] Once it is burned and raised, the smoke can simply be breathed in while suspended in the chamber, leaving return of the bottle to the water for additional upward pressure during inhalation essentially a matter of preference.

In its crudest form, it requires only an upper chamber and a taped plastic grocery bag or similar to provide the suction.

A joint can contain from 0.4 g to well over 1 g and blunts can contain up to 3 g of cannabis,[14] while the bucket bong only uses about 0.1 to 0.3 g.[15] In the United States, under the Federal Drug Paraphernalia Statute, which is part of the Controlled Substances Act, it is illegal to sell, transport through the mail,[16] transport across state lines, import, or export drug paraphernalia, meaning that the bong is illegal.

[19][20] In countries and states where use of cannabis is illegal, some retailers insist that bongs are intended for use with tobacco in an attempt to circumvent laws against selling drug paraphernalia.
