Cigarette and cigarette filter

Abstract

A basic amino acid or a basic amino acid salt is added to a cigarette or a cigarette filter. It is desirable for the basic amino acid or the basic amino acid salt to be added in an amount of at least 1 mg/cigarette. It is also desirable for the basic amino acid or the basic amino acid salt to be added to the cigarette or the cigarette filter in the form of an aqueous solution. Also, it is possible to add a surfactant to the cigarette or the cigarette filter together with the basic amino acid or the basic amino acid salt.
