The invention discloses a determination method for a suction easiness degree of a cigarette. The determination method has the technical characteristics that the suction easiness degree of the cigarette is defined by certain cigarette suction pressure and effective cigarette suction amount under suction time; the cigarette suction pressure is superficially characterized by a suction vacuum degree before cigarette suction; and the effective cigarette suction amount is superficially characterized by adopting a fourier transform infrared spectrum (FTIR) method through signal strength of a Gram-Schmidt spectrum measured by continuous scanning. The determination method disclosed by the invention can do scientific and simple definition on the suction easiness degree of the cigarette and can conveniently apply an instrument analysis manner to measure; and the fourier transform infrared spectrum method is used for determining the effective cigarette suction amount and the determination method has the advantages of simplicity in operation, fast analyzing speed, high sensitivity and good experiment repeatability.
