The invention relates to a cigarette paper having the conventional burning additives and fillers containing from 20 to 50% by weight of bast fibres of fine fibrillation, with which a degree of grinding of at least 85 SR is produced. The cigarette paper produced according to this formulation has a pore structure which greatly promotes diffusion, in particular diffusion of carbon monoxide.
