1. A cartridge for use with a vaporization device, the cartridge comprising:
a reservoir configured to contain a vaporizable material;
a wick configured to draw the vaporizable material from the reservoir to a vaporization region, the wick including a porous wicking material surrounding at least a part of a hollow core, the porous wicking material allowing a radially directed absorption of the vaporizable material from the hollow core towards an outer surface of the wick, the porous wicking material further allowing an axially directed absorption of the vaporizable material along a length of the wick; and
a heating element disposed within the vaporization region and adjacent the wick, the heating element configured to heat the vaporizable material drawn from the reservoir.
