Quick answer. Cannabis concentrates are extracts that strip the cannabinoids and terpenes out of flower into a much more potent form — usually 60% to 90%+ THC, versus 15% to 30% for flower. The names (shatter, wax, badder, sauce, diamonds, live resin, live rosin) mostly describe texture and how the extract was made. Solventless options like live rosin sit at the top for purity and flavor.
If the concentrate menu reads like a foreign language, you're not alone. Here's what each term actually means, how strong these products are, and how to pick one.
What is a cannabis concentrate?
A concentrate is what you get when you separate the active parts of the cannabis plant — the cannabinoids (THC, CBD) and the aromatic terpenes — from the plant material around them. Strip away the leaf and stem and you're left with a thick, potent extract.
That concentration is the whole point. A gram of flower might be 20% THC; a gram of concentrate is routinely 70-90%. A little goes a long way, which makes concentrates efficient — and easy to overdo if you treat them like flower.
The main types, by texture
Most of the names on a concentrates menu describe consistency rather than strength:
- Shatter — hard and glassy, snaps like brittle candy. Stable and potent, a little less terpene-forward.
- Wax / budder — opaque and soft, like the name suggests. Easy to scoop and handle.
- Badder / batter — whipped to a cake-frosting texture. Big flavor, very workable.
- Sugar — a wet, grainy texture that looks like coarse sugar, rich in terpenes.
- Sauce — a syrupy, terpene-heavy extract, often studded with crystals. The most flavorful end of the menu.
- Diamonds — near-pure THCA crystals, the highest-potency option, usually dabbed alongside a little sauce.
- Hash & rosin — traditional hash and its pressed cousin, rosin (more on this below).
Solvent vs. solventless
How a concentrate is made tells you a lot about it.
Solvent extractions use butane (BHO), CO2, or ethanol to dissolve the cannabinoids out of the plant, then purge the solvent off. This is efficient and affordable, and it produces most shatter, wax, and distillate. In Massachusetts, every solvent-extracted product is lab-tested for residual solvents, so a licensed BHO product has to meet a strict purge standard.
Solventless extractions use only ice water, heat, and pressure — no chemicals at all. Ice-water hash and live rosin are the headliners here. Solventless is the cleanest, most prized end of the menu, and it costs more because it's labor-intensive.
"Live," cured, and why fresh-frozen matters
You'll see the word live a lot — live resin, live rosin. It refers to the starting material. Live concentrates are made from flower that was frozen fresh at harvest, locking in the terpenes that give cannabis its truest smell and flavor. Cured concentrates come from dried, cured flower — still excellent, but with a deeper, less bright profile.
So the two big "live" products break down like this:
- Live resin = fresh-frozen flower + solvent extraction. Terpene-rich and flavorful.
- Live rosin = fresh-frozen hash + heat and pressure, no solvent. The connoisseur's pick.
How strong are they, really?
Most concentrates test between 60% and 90% THC. THCA diamonds can push past 90%. Compared with flower, that's roughly three to five times the potency by weight — which is why dabs are measured in rice-grain-sized amounts, not bowls.
If you're new to concentrates, start with the smallest dab you can manage and wait. You can always take more; you can't take less.
How to consume concentrates
There's more than one way in:
- Dab rig or e-rig — the classic method. Heat the nail (an e-rig sets the temperature for you), drop a small dab, and inhale. Lower temperatures (around 500-580°F) preserve flavor; higher temps make bigger, harsher clouds.
- Top a bowl — lay a bit of badder or rosin on top of flower in a pipe or bong. No special gear required.
- Vape cartridges — many vape carts are filled with concentrate (distillate, live resin, or live rosin), which is the most beginner-friendly way to enjoy a concentrate.
Storing concentrates
Light, heat, and air degrade both potency and terpenes. Keep concentrates in an airtight, non-stick container — silicone or glass — somewhere cool and dark. Sticky, wet textures like sauce can be firmed up briefly in the fridge for easier handling. Always scoop with a dab tool rather than your fingers.
Buying concentrates in Western Massachusetts
Every concentrate sold by a licensed Massachusetts dispensary comes with a Certificate of Analysis (COA) confirming its potency and clearing it for solvents, pesticides, heavy metals, and microbials. That testing is exactly what separates a regulated product from anything bought outside the legal market.

Frequently asked questions
What is the strongest cannabis concentrate?
THCA diamonds are typically the most potent, often testing above 90% THC. Most other concentrates — shatter, wax, badder, live resin, live rosin — land somewhere between 60% and 90%, far above flower's usual 15-30%.
What is the difference between live resin and live rosin?
Both start from fresh-frozen flower, so both are terpene-rich. The difference is the method: live resin uses a solvent (usually butane) to extract, while live rosin is solventless, pressed with only heat and pressure. Live rosin is cleaner and pricier.
Do I need a dab rig to use concentrates?
Not always. A dab rig or electronic e-rig is the classic way, but you can also add a small amount of badder or rosin on top of a bowl of flower, or buy a concentrate already loaded into a vape cartridge.
Are cannabis concentrates safe?
Concentrates sold by a licensed Massachusetts dispensary are lab-tested for potency, residual solvents, pesticides, heavy metals, and microbials before they can be sold. The main risk is dosing — they are far stronger than flower, so start small.
How much concentrate can I buy in Massachusetts?
Massachusetts caps adult-use concentrate purchases at 10 grams per person per day, tracked statewide through the Metrc system.
