Concentrates & Rosin
Concentrates are cannabis extracts that isolate and concentrate cannabinoids and terpenes from the plant material. Rosin, live resin, hash, and distillate are all concentrates, but they're produced very differently and matter to patients for very different reasons. Concentrates are typically 60–90% cannabinoids by weight — many times more potent than flower.
Within minutes (vaporized) or 45+ minutes (in edibles or infusions)
1–3 hours vaporized; longer if consumed orally
Similar to vape (inhaled) or edible (oral)
Best for
- • Patients with high tolerance where flower or standard vape isn't sufficient
- • Precise, potent dosing for severe chronic pain or intractable symptoms
- • Patients seeking full-spectrum extracts (live rosin) with intact terpene profiles
- • Cancer patients using RSO (Rick Simpson Oil) style extracts under practitioner guidance
Watch-outs
- • Very easy to over-medicate — dose by grain of rice, not by dab
- • Solventless concentrates (rosin) are cleaner than solvent-extracted (BHO, PHO) — check residual solvents on COA
- • Tolerance rises fast with regular concentrate use
- • Concentrates are the format most likely to intimidate new patients — start with tincture or vape first
Kentucky-compliant concentrates must show residual solvents testing on the COA. Rosin (solventless) and live resin (BHO-extracted) are distinct products with different processing profiles.
