There is provided a vaporizable formulation comprising (i) one or more solvents; and (ii) less than about 1 wt % of a cooling agent based on the weight of the vaporizable formulation; wherein the cooling agent volatilizes at a higher temperature than menthol at atmospheric pressure. There is also provided a vaporizable formulation comprising (i) one or more solvents; and (ii) less than about 12 wt % of a cooling agent based on the weight of the vaporizable formulation; wherein the cooling agent volatilizes at a higher temperature than menthol at atmospheric pressure and is a compound of formula (I) or a salt and/or solvate thereof as defined herein.
