Cigarette with a composite wrapper consisting of two superposed thin sheets of paper fabricated of vegetable fiber stocks. The outer sheet is a porous conventional cigarette paper of good combustibility and ashing qualities. The inner sheet which is in contact with the tobacco is fabricated of uncoated, unsized and unimpregnated vegetable fiber stock and is essentially so poreless as to be practically impervious to the passage of air therethrough. The inner wrapper sheet burns at a rate slower than the tobacco underneath and the outer sheet in such wise that substantially all the air which is drawn through the cigarette during combustion is constrained, like in cigars and pipes, to pass axially through the burning coal, and thus to be less oxidizing than in conventional cigarettes. The produced smoke gives the feeling of being richer than that from conventional cigarettes made with the same tobacco, and tends to reduce inhalation.
