Abstract

A nicotine composition is provided, including a non-aqueous solvent; at least 0.2 percent by weight of nicotine based on the weight of the nicotine composition; a first ratio by weight of (β-ionone+β-damascenone) to (phenol) of greater than 0.25; and a second ratio by weight of (furaneol+(2,3-diethyl-5-methylpyrazine)*100)) to (nicotine) of greater than 5×10−4. A cartridge including the nicotine composition, and a method of preparing the nicotine composition, are also provided.
