Abstract
Methods of filling a tank reservoir of an electronic cigarette or cartridge for an electronic cigarette with a vaporizable material so that air is not entrapped within the cartridge. In particular, described herein are methods of filing a tank volume of a cartridge for an electronic cigarette from a bottom or side surface opposite a wick so that the wick remains at least partially dry and can vent air during filling until the tank volume is full.
