A prefilled container of cannabis oil, most often sold in .5g, 1g, and 2g volumes, with a built-in heating element and mouthpiece. It attaches to a rechargeable battery that is sold separately. Most use the universal "510" screw thread, so one battery works with cartridges from many makers.

The battery heats the cartridge's heating element, turning the oil into an aerosolized vapor that you inhale. The oil inside a cartridge varies: distillate with added terpenes, live resin, live rosin, etc. The menu/product listing and lab report should state which type of extract the cartridge contains.

A cannabis concentrate made without solvents (solventless). Live rosin is made by pressing ice-water hash extracted from fresh-frozen plant material. Keeping the material frozen, or "live", preserves volatile compounds that may be lost during the drying/curing process.

On a menu, "Indica" signals the effects the seller expects: relaxing, sedating, felt more in the body, suited to evening. That expectation is tradition, not a measured property of the product.
