What is shatter?
Shatter is a cannabis concentrate. It forms a glass-like sheet that snaps when bent. The name comes from that texture. Makers pull cannabinoids and terpenes from plant material with a solvent, then purge the solvent with heat and vacuum. The finished product is thin, amber, and brittle.
Most shatter on the market is THC shatter. Lab tests from state-licensed programs put THC content between 60% and 90%. CBD shatter is a separate product. It is made from hemp and carries 0.3% THC or less.

How shatter is made
- Extraction: butane, propane, or ethanol strips cannabinoids from plant material.
- Winterization: chilled ethanol separates fats and waxes.
- Purging: vacuum and heat remove leftover solvent.
- Pressing: the extract spreads into a film and cools into a sheet.
Solvent residue is the main quality control point. State labs test for butane, propane, and ethanol. Limits differ by state and sit in the hundreds to thousands of parts per million. Ask for a residual solvent panel, not just a potency panel.
THC content and effects
Dab hits deliver a large THC dose in one inhalation. Users report fast onset, in the range of seconds to a few minutes. Effects include dry mouth, elevated heart rate, and impaired short-term memory. High doses raise the risk of anxiety and paranoia. Tolerance builds fast with daily use.
The Ultimate Guide to Rosin Extraction for CBD
Shatter vs other concentrates
- Wax and budder: softer, opaque, more malleable.
- Live resin: made from fresh frozen plant, higher terpene content.
- Rosin: pressed with heat and pressure, no solvent.
- Distillate: refined to near-pure THC, few terpenes.
Shatter holds terpenes less well than live resin. Terpenes evaporate at low heat, so a stable sheet often means a milder smell.
Legal status in the US
Cannabis sits on Schedule I under federal law. THC shatter is legal only under state medical or adult-use programs. Rules on possession limits, purchase caps, and packaging differ by state.
Hemp is treated as a separate crop. Hemp-derived products must stay at or below 0.3% THC on a dry weight basis. CBD shatter falls in that category. Some states add their own limits on hemp extracts, so check state law before you buy.
Is there CBD shatter?
Yes, but supplies are thin. Pure CBD isolate is a crystalline powder, not a sheet. A product labeled CBD shatter usually blends CBD distillate with terpenes to reach a brittle texture. Labels should show a batch test from an ISO 17025 lab. Look for three numbers: total CBD in milligrams per gram, THC percentage, and a solvent panel. If a listing shows none of them, treat the shatter as unverified.
Risks
Dabbing uses a torch or an e-nail at 400 F to 600 F. Contact burns are common. Case reports document lung injury tied to high-temperature concentrate use. Untested shatter can carry residual solvent, pesticide, or mold. High-THC shatter raises the chance of a bad reaction in new users.
What to check before you buy
- Batch-specific lab report with a date inside 12 months.
- Total THC on the label, not just total cannabinoids.
- Residual solvent results with values below your state limit.
- Terpene list, if the seller claims a strain profile.
- Storage advice: cool, dark, and sealed, since heat turns shatter sticky.
Unknown: no federal standard exists for concentrate labeling. Numbers on a jar come from the maker and the state program that tested it.
