Cartridge
A cartridge includes a body with a side wall and at least one lid arranged to cover a top or a bottom, or both. The cartridge comprises a cavity inside the body configured for receiving an aerosol-forming substrate. The lid includes an inner layer facing the cavity and an outer layer facing an outside of the body. The inner layer comprises a weakened region. When the outer layer is removed, the weakened region of the inner layer forms an aperture. The cavity is in fluid communication with an outside of the cartridge body via the formed aperture. The aerosol-forming substrate may include tobacco. The cartridge may be a shisha cartridge and the aerosol-forming substrate may be a shisha substrate, such as hookah tobacco.
