A simple vaporizing device with four concentric tubes and a wire mesh wick for volatizing, by vaporization, and inhaling one or more constituents of various vaporizable substances. The device is operated using the flame from a standard butane cigarette lighter or other flame producing devises as the sole heat source, and the user's inhalation process for air flow. Concentric tubes, an inner tube with two open ends to provide a direct pathway for the flow of air and vapor; and outer tubes with open ends, one moveable, are arranged to provide for the application, vaporization, and delivery of the vaporizable substance as a single dose.
