A pre-filled container of cannabis oil or concentrate designed for use with an e-cigarette or vape rig. Weed cartridges, or “carts,” are offered in multiple formats, from 510-threaded cartridges that twist onto a battery to pods that magnetically snap into place. Pre-filled vape cartridges built with ceramic tanks run less of a risk of ruining the flavor, as they do not rely on a wick or metallic coil to vaporize the oil.
