Abstract: A handheld vaporization device comprises a heating chamber for heating a substrate of volatile compound so as to yield vapour including the volatile compound. The heating chamber includes a closable opening, for example using a plug, to receive the substrate. The heating chamber also includes scavenging channels for allowing air to enter therein. The handheld vaporization device further comprises a vapour chamber mounted to the heating chamber so as to be in fluid communication therewith for receiving the vapour scavenged therefrom and has a vapour outlet for releasing the vapour including the volatile compound. By applying heat to the exterior of the handheld vaporization device's heating chamber, with a flame or any heating device, the confinement resulted from the heating chamber and the emissivity of its walls create a uniform heat across the substrate which is deposed into it. Heating the substrate in this manner permits great efficacy in extraction of undiluted organo-volatile elements.
