Resin

Resin is a polysemous term in cannabis with three meanings that must be distinguished. First, plant resin (natural) refers to the sticky trichome exudate containing cannabinoids, terpenes, and flavonoids — the raw material underlying every concentrate. Second, cured resin (concentrate) refers to a solvent-extracted concentrate made from dried and cured cannabis, in contrast to live resin made from fresh-frozen material. Third, reclaim resin refers to the oxidized, darkened residue that accumulates inside dab rigs, vaporizers, and pipes after use — technically consumable but chemically degraded. Resin in the cured-concentrate sense is distinct from rosin, which is a solventless heat-and-pressure product. The two are near-homophones and are frequently confused by new consumers; the one-letter difference carries the entire solvent/solventless distinction. Cured resin potency generally runs 60–85% THC with an amber to dark brown color profile, reflecting the oxidation of chlorophyll and minor compounds during drying and curing of the source flower. → See also: Live resin, Rosin, BHO, Reclaim [Part 4]
