Cannabis concentrate is any cannabis product that has been processed to keep only the most desirable compounds, primarily THC and terpenes, while removing plant material. The result is a product that typically contains 50 to 95% THC, compared to roughly 15 to 25% in regular flower. Concentrates come in many forms, from glassy shatter to creamy wax, and they can be made through several different extraction methods.
How Concentrates Compare to Flower
The simplest way to understand concentrates is by the numbers. In 2022, Washington State data showed flower averaged 21% THC while concentrates averaged 69%. Some concentrate types, particularly distillates, test above 90%. Kief and traditional hash sit on the lower end, around 50 to 80%, while products like wax, rosin, and shatter generally range from 60 to 90%.
Beyond potency, concentrates differ from flower in their chemical makeup. Terpenes, the aromatic compounds responsible for flavor and scent, are the second most abundant class of compounds in concentrates after cannabinoids. How those terpenes survive the extraction process (or get added back in afterward) shapes the flavor, aroma, and overall experience of the final product.
Solvent-Based Extraction
Most commercial concentrates are made using chemical solvents that dissolve the cannabinoids and terpenes out of the plant material. Common solvents include butane, propane, ethanol, and carbon dioxide (CO2). In butane or propane extractions, the gas is cooled or pressurized into a liquid, passed through cannabis flower, and then evaporated off in a step called purging. What’s left behind is a concentrated oil rich in THC and terpenes.
The purging process is critical. If solvents aren’t fully removed, they can remain as residue in the final product. Pressurizing flammable gases like butane also creates serious safety hazards, which is why professional extraction happens in closed-loop systems in licensed facilities. How the purging is done, along with variations in moisture and heat, determines the final texture of the concentrate. The same basic extraction can produce shatter, wax, budder, or crumble depending on post-processing conditions.
Solventless Extraction
Solventless methods use only physical force, temperature, or water to separate trichomes (the tiny resin glands on cannabis flowers) from the plant. The three traditional approaches are hand-rubbing, dry-sifting, and ice water extraction. Dry sift, often called kief, is made by agitating dried flower across fine screens so the trichome heads break away. Ice water extraction, which produces “bubble hash,” works by soaking plant material in ice water to make trichomes cold and brittle, then agitating them loose with spinning, stirring, or vibration.
Rosin takes solventless extraction a step further. A rosin press uses two heated metal plates to squeeze hash or flower under high pressure, forcing the resin out as a golden, dab-ready oil. Because no chemical solvents are involved, rosin has become popular with consumers who want a cleaner product. The tradeoff is typically lower yields compared to solvent-based methods.
Common Types and Textures
The names you see on dispensary shelves mostly describe physical texture rather than fundamentally different products. Many are made through the same butane or propane extraction, just finished differently.
- Shatter: Glassy and brittle, it snaps when bent. Produced by purging at lower temperatures with minimal agitation.
- Wax: Soft and creamy, easy to scoop. More agitation during purging introduces air and creates the waxy consistency.
- Budder: Whipped during processing, giving it a smooth, butter-like texture.
- Crumble: Dry and crumbly, it breaks apart easily. Made by purging at lower heat for a longer time.
- Kief: Loose, powdery trichome heads collected from dry sifting. Lower potency than other concentrates, typically 50 to 80% THC.
- Rosin: Solventless oil pressed from hash or flower using heat and pressure.
Live Resin and Live Rosin
Most concentrates start with dried and cured cannabis. Live resin is different. The plant is flash-frozen immediately after harvest to subcritical temperatures, then extracted using solvents like butane or CO2 while still frozen. This preserves a much broader spectrum of terpenes and cannabinoids that would otherwise degrade during the weeks-long drying and curing process. The result is a concentrate with noticeably stronger flavor and aroma that more closely captures the scent of a living cannabis plant.
Live rosin follows the same fresh-frozen philosophy but uses solventless methods. The frozen flower is processed into bubble hash through ice water extraction, then pressed into rosin. It’s widely considered a premium product because it combines the terpene preservation of fresh freezing with the chemical-free appeal of solventless processing.
Full Spectrum vs. Distillate
These two categories describe how much of the original plant chemistry makes it into the final product. Full-spectrum concentrates preserve the plant’s natural range of cannabinoids, terpenes, and flavonoids. The idea is that these compounds work together in what’s often called the “entourage effect,” where the combined profile produces a more balanced, nuanced experience than any single compound alone.
Distillate goes the opposite direction. The oil is refined to isolate a single cannabinoid, usually THC, producing a nearly flavorless product that can test above 90% THC. Terpenes are often reintroduced afterward for flavor, but the natural complexity of the plant is largely gone. Distillate is the base for most vape cartridges and many edibles because of its potency and versatility. If you want maximum THC strength, distillate delivers that. If you care about flavor and a more well-rounded effect, full-spectrum is the better fit.
How Concentrates Are Used
The most common method is dabbing, which involves heating a small amount of concentrate on a hot surface (called a nail or banger) and inhaling the vapor. Temperature matters significantly. Low-temp dabs between 400 and 450°F produce smoother, more flavorful vapor because terpenes vaporize gently at those temperatures. At 450°F, you start getting denser vapor with a stronger effect while retaining good flavor. Temperatures above 600°F are harsh, can burn lung tissue, and should be avoided.
Vape pens offer a more portable option. Pre-filled cartridges, usually containing distillate or live resin, attach to a battery and heat the oil at controlled temperatures. Some concentrates like crumble or kief can also be sprinkled on top of flower in a bowl or joint to boost potency.
Onset and Duration of Effects
When inhaled through dabbing or vaping, concentrates take effect almost immediately, within seconds to a few minutes. Because THC levels are so much higher than flower, the effects are considerably more intense. This rapid onset and high potency is worth keeping in mind if you’re new to concentrates. The effects typically last 2 to 4 hours, shorter than edibles or tinctures.
Concentrates also appear in oral products. Cannabis oil placed under the tongue takes roughly 45 to 60 minutes to kick in and lasts 4 to 6 hours. Edibles made with distillate can take 30 minutes to 2 hours to fully develop and last 6 to 8 hours. The route of consumption changes the experience substantially, even when the starting material is the same concentrate.
