A non-combustible simulated cigarette inhaler device includes a hollow cylindrical tube having an open air inlet end and an opposed open air outlet end to be placed in the mouth of a user. A first element of air permeable material is located within the hollow tube across a segment of the transverse cross-sectional area of the tube and a second element of air permeable material is located within the hollow tube across the remaining segment of the transverse cross-section of the tube. The first element is impregnated with a nicotine free base material. The second element is impregnated with an acid which is reactive with the free base to form a salt having a pH in the range of approximately 5 to 7. Examples of such acids are 2-butenoic acid, 2-methyl-2-butenoic acid, isocaproic, caproic, and caprylic acids. |
