Concentrate

Concentrate is the industry umbrella term for any cannabis product produced by separating and concentrating active cannabinoids and terpenes from plant material, raising potency relative to flower. The category encompasses hash, kief, rosin, shatter, wax, BHO, CO₂ oil, distillate, tinctures, and isolate. Regulatory definitions vary meaningfully across U.S. states. California DCC at 4 CCR §15000(h) defines cannabis concentrate as "cannabis that has undergone a process to concentrate one or more active cannabinoids... includes, but is not limited to, kief, tinctures, capsules, suppositories, extracts, butter, vape cartridges, inhaled products (e.g., dab, shatter, and wax), and tablets." Under California AB 8 (Chapter 248, Statutes of 2025), which took effect January 1, 2026, the definition expressly includes "extracts, oils, hash, dab, shatter, rosin, wax, and the separated resin, whether crude or purified." Effective January 1, 2028, CBD isolate at ≥99% purity is explicitly excluded from the concentrate definition; ⚠️ a pending 2026 cleanup bill (AB 2250, not yet enacted as of April 2026) would add CBN isolate to that exclusion. Colorado MED at 1 CCR 212-3 uses "Regulated Marijuana Concentrate" as an umbrella subdivided by process type: Water-Based, Solvent-Based, and Heat/Pressure-Based. Oregon OLCC under ORS 475C.009 defines "cannabinoid concentrate" as a substance obtained by mechanical extraction, non-hydrocarbon solvent, CO₂ without high heat or pressure, or other authorized process. Washington LCB under WAC 314-55 uses "cannabis concentrate" as the umbrella inventory and product category and imposes a 1-gram single-unit inhalable limit. → See also: Extract, Isolate, BHO, Rosin, Distillate
