Cannabis concentrates are highly potent products created by extracting the most desirable compounds from the cannabis plant. These typically include cannabinoids such as THC or CBD, along with aromatic terpenes that contribute to flavor and effects. By removing excess plant material, concentrates deliver a stronger experience using a smaller amount of product.

Concentrates are available in several forms—such as wax, shatter, budder, resin, and rosin—each differing in texture, strength, and extraction method.

THCa hash rosin is a solventless concentrate. The trichomes are washed off fresh frozen flower with ice water, dried into hash, and then pressed with low heat and pressure into rosin. No butane, ethanol or other solvents are used, so it keeps the strain's full terpene profile, and ours has zero additives and no plant matter. Our THCa hash rosin comes in indica and sativa strains, and our current strains test between 79% and 86% THCa. Each product tile shows its batch's number. To learn more, read what hash rosin is and why you should care.

THCa diamonds are THCa in its purest crystalline form. Ours start as a hydrocarbon extract called sauce. Diamond mining then grows it into crystals, and the solvents are removed. Our 99% THCa Diamonds lab tested at 99.6% THCa and have zero additives. Because they're nearly pure THCa, they have little flavor of their own and are the strongest product we sell, so start with a very small amount.

Choose hash rosin for flavor and a strain-specific experience. It's solventless, rich in terpenes, and comes in indica and sativa strains. Choose diamonds for maximum potency at a lower price per gram. They're 99% THCa with little taste of their own, and you can crush them over a bowl or joint of THCa flower to make it stronger.

Use a dab rig or an electronic rig (e-rig) such as a Puffco. Heat the banger or chamber, add a portion about the size of a grain of rice, and inhale slowly. The heat turns the THCa into THC, so effects come on within moments. Lower temperatures keep more of the flavor. You can also add a little to the top of a bowl or joint. For more, read dabbing vs smoking: pros and cons.

Both come in 1 g and 3 g. THCa hash rosin is $43.98 for a 1 g jar and $129.98 for a 3 g jar. THCa diamonds are $21.99 for 1 g and $61.99 for 3 g. Orders of $100 or more ship free, and orders placed Monday through Friday before 1:00 pm ET ship the same day.

Every batch is tested by an independent third-party lab, and the certificate of analysis (COA) is linked on each product page. THCa diamonds also have a separate safety test report. To check the exact batch you received, enter the lot number from your label in our lab report library, which holds more than 770 reports.

Cannabis concentrates may contain THCa, THC, or a combination of both, depending on how the product is made and how it’s consumed. In its natural state, cannabis produces THCa, which is non-psychoactive and only becomes THC when exposed to heat through a process known as decarboxylation.

Certain concentrates, such as hash rosin or THCa diamonds, are high in THCa until they are dabbed or vaporized. Once heat is applied, the THCa converts into THC, producing psychoactive effects. Other concentrates, like distillate, are already converted into active THC and can be used right away in vapes, edibles, or tinctures.

Arete concentrates may contain trace amounts of THC but always remain within legal limits. Even so, consuming concentrates can still result in a failed drug test.

Cannabis concentrates stand out from traditional flower because of their increased strength and refined composition. With a much higher concentration of cannabinoids, concentrates allow users to achieve their desired effects using significantly less material.

By removing excess plant matter, concentrates often deliver a smoother and more flavorful experience. Whether consumed through vaping, dabbing, or infused into edibles, they offer an efficient and elevated way to experience cannabis.
