Quality Grown From Experience AbsoluteXtracts—ABX—is a homegrown Northern California company committed to providing patients with pure, safe, and potent cannabis concentrates. These cannabis plant-starts are grown in greenhouses and on small family farms throughout Northern California. When ready, they’re harvested and transported to Santa Rosa for processing. The plant materials are tested for pesticides, molds and bacteria. After passing inspection, the herb is dried, cured and processed in a pharmaceutical grade “clean” room. We use clean, high pressure carbon dioxide at low temperatures to extract the cannabis oil. We employ proprietary methods to preserve the terpenes, that give each strain its distinctive smell and flavor. We package our cannabis oil in our own specially made cartridges that are designed to ensure easy flow and a reliable draw. We add absolutely no additives.
