Abstract

A smoking article 1 comprises a tobacco rod 3 with at least two tobacco portions 4, 5 and a wrapper 6 surrounding the tobacco portions, with the portions being spaced from each other to form a cavity 7 therebetween. The wrapper 6 is formed with a reduced propensity to burning in a region of the cavity 7. This region forms a burn suppressant zone operable to extinguish the smoking article, with the region also being provided with at least one line of weakness 10, 11. The burn suppressant zone in the wrapper 6 may be provided by treatment with material to reduce its propensity for burning and/or providing the wrapper with a section having lower ait permeability compared to the remainder of the wrapper. The smoking article preferably includes an outer tobacco portion 4, an inner tobacco portion 5 and a filter 2, with the line(s) of weakness 10, 11 enabling removal of a burnt end of the outer tobacco portion. The remaining wrapper 6 which originally surrounded the cavity 7 may be used to protect the tobacco in the inner portion 5 for later use (figure 3).
