A cannabis concentrate is a product made by removing plant material from cannabis to leave a dense form of cannabinoids and terpenes. Concentrates often test between 60% and 90% cannabinoid content, compared with 15% to 30% in dried flower. That jump in potency is why dose control matters more with a cannabis concentrate than with any other form of the plant.
What forms do cannabis concentrates take?
Concentrates split into two groups based on how the resin is pulled from the plant: solventless and solvent-based. Solventless products use heat, pressure, water, or ice. Solvent-based products use butane, propane, or ethanol to strip out cannabinoids, then purge the chemical.

Solventless concentrates
- Kief: the trichome dust that collects in a grinder. The least processed option.
- Hash: kief pressed with heat until it forms a solid block.
- Bubble hash: resin separated with ice water and filter bags.
- Rosin: flower or hash squeezed between heated plates. No chemicals involved.
Solvent-based concentrates
- Shatter: a glassy, brittle slab with a stable shelf life.
- Wax and budder: whipped extracts with a soft, creamy texture.
- Live resin: made from fresh frozen plant, which preserves more terpenes.
- Distillate: refined to a single cannabinoid, often above 90% purity.
- RSO: a thick, dark full-spectrum extract made with ethanol.
What is the difference between THC and CBD concentrates?
THC and CBD concentrates use the same extraction methods, but the source plant and final cannabinoid profile differ. THC concentrates come from marijuana and produce intoxicating effects. CBD concentrates come from hemp, which federal law caps at 0.3% THC or less, so they do not get you high.

Both kinds can be sold as full-spectrum (keeping other cannabinoids and terpenes) or as isolate (one purified compound). Full-spectrum CBD distillate usually lands between 70% and 90% CBD, while CBD isolate can reach 99% purity.
How potent are cannabis concentrates?
Potency depends on the starting material, the extraction method, and how much refining happens afterward. Kief and hash sit at the low end of the scale. Distillate sits at the top.
- Kief: 20% to 50% THC
- Hash: 40% to 60% THC
- Rosin, shatter, wax, live resin: 60% to 85% THC
- THC distillate: 85% to 99% THC
- CBD distillate and isolate: 70% to 99% CBD
Package labels are not proof. A Certificate of Analysis from an accredited lab is the only reliable potency number.
How do you use a cannabis concentrate?
Inhaled concentrates go into a dab rig, an e-rig, or a concentrate vaporizer pen. Most dabbing happens between 450°F and 600°F. Higher heat burns off terpenes and produces harsh vapor.
Concentrates also work as an add-on. Sprinkle kief or hash over a bowl, fold rosin into a joint, or stir distillate into a batch of edibles. Any concentrate you plan to eat needs decarboxylation first.
What should you check before buying a cannabis concentrate?
- Lab results. Look for a batch-specific COA, not a generic one.
- Residual solvents. Solvent-based extracts should show them below state limits.
- Contaminants. Pesticides, heavy metals, and mold tests should all pass.
- Cannabinoid profile. Confirm total THC, total CBD, and the ratio between them.
- Hemp compliance. For CBD products, verify the THC level is 0.3% or lower.
How should you store cannabis concentrate?
Heat, light, and air break down cannabinoids and terpenes. Keep concentrates in a sealed glass jar, out of sunlight, at room temperature or cooler. Avoid plastic, which can cling to sticky extracts and pull terpenes out of the product.
Shatter and rosin hold up for months in a fridge. Distillate syringes last even longer. Soft waxes and live resins lose flavor fast, so plan to finish them within a few months.
Is cannabis concentrate legal in the US?
The 2018 Farm Bill made hemp-derived concentrates with 0.3% THC or less legal at the federal level. Marijuana-derived concentrates remain illegal under federal law, though many states permit them for medical or adult use.
State rules set possession limits, purchase amounts, and where you can consume. Check your state cannabis authority before ordering anything.
What are the risks of using cannabis concentrate?
High potency raises the odds of anxiety, paranoia, and impaired coordination. New users face the highest risk. Start with a dose the size of a grain of rice and wait at least 10 minutes before taking more.
Inhaled concentrates carry lung risks. The CDC tied vitamin E acetate in THC vaping products to an outbreak of EVALI, a severe lung injury, in 2019. Buy from licensed sellers that publish lab results and skip unregulated cartridges.
Frequently asked questions
Is a cannabis concentrate the same as CBD oil?
No. CBD oil is a carrier oil infused with CBD, usually at 5% to 20% strength. A concentrate is a purified extract with a far higher cannabinoid content, and it gets diluted to make oils.
Can you eat cannabis concentrate?
Yes, if it has been decarbed. Raw extract holds acidic cannabinoids like THCA and CBDA, which behave differently in the body. Heat converts them into THC and CBD.
Which concentrate suits a beginner?
Low-potency options such as kief, hash, or a full-spectrum CBD concentrate. Pair them with a vaporizer you can control, so doses stay small and measured.
