All organic terpenes! Live resin is a form of cannabis concentrate produced using fresh flower as opposed to dried and cured buds. This method retains the terpenes that are lost during the drying and curing process. Because the flavorful terpenes remain intact, live resin is considered a high-quality, connoisseur-level product.

Note: Live Resin will oxidize at the top (turning darker) and produce small bubbles inside the cartridge which is normal.
