Shisha cartridge

Abstract

A shisha cartridge comprises a body defining a cavity. An aerosol-forming substrate is disposed in the cavity. The cartridge also comprises a heatable surface area. The ratio of the heatable surface area of the cartridge to the volume of the cavity is in a range from about 1 cm −1 to about 4 cm −1 . The maximum inner width of the cavity may be 4 cm. The height of the cavity may be 3 cm or greater.
