A cigarette including a first rolling material of a first area density that is between about 50 and 100 g/m.sup.2 and a hollow body with a support tip arranged inside of a proximal end of the hollow body. The hollow body is loaded with a smokeable material. The cigarette is plugged at a distal end of the body using a second rolling paper with a lower area density compared to the first rolling material. Various other features are disclosed, including a filter tip arranged inside of a proximal end of the hollow body. The cigarette shell includes a second rolling paper with a lower area density compared to the first rolling material, forming a sleeve of which a first portion extends within the body and of which a second portion projects from the body out from a distal end thereof in a longitudinal direction of the body.
