A cigarette paper is disclosed, which contains at least one combustible salt, the concentration c(x) of which varies along a direction x of the cigarette paper. For the location-dependent concentration c(x) over an interval of length L, the following applies for all x from the interval [0, L]: f(x) — Δ c ≤ c(x) ≤ f(x) + Δ c . In this respect 3 cm ≤ L ≤ 11 cm, f(x) is a function that is monotonic over the interval [0, L] but not constant over the entire interval, and Δ c ≤ 1% by weight, preferably ≤ 0.7% by weight, particularly preferably ≤ 0.5% by weight, very particularly preferably ≤ 0.3% by weight and in particular preferably ≤ 0.15% by weight and Δ c > 0% by weight, in each case in relation to the mass of the cigarette paper. |
