Cannabis Extracts
A fundamentally different animal

Bubble hash is made by agitating cannabis in ice water, causing the trichome heads to snap off and fall through a series of mesh screens. The finest fractions — collected at the 90–120 micron range — produce the cleanest, most intact trichome heads. That's what ends up in 6-star.

The name "full melt" describes exactly what happens when you apply heat: it bubbles, liquefies, and vaporizes with almost nothing left behind. That clean melt behavior is the defining trait. Most hash labeled "full melt" on the market is realistically 5-star.

What makes 6-star rare: Top-tier starting material (fresh-frozen preferred), skilled washing technique, careful micron selection, and ideal drying — typically a freeze dryer. Any one of these done poorly drops you a star. Within cannabis culture, 6-star is a connoisseur product. It gets judged at competitions like the Emerald Cup. It's considered closer to the original expression of the plant than anything made with solvents.

Rosin is solventless cannabis oil made by pressing cannabis material between heated plates at controlled pressure. Heat and pressure force the trichome oils out of the plant material. No solvents involved — ever. What you get is a complete-spectrum extract: THC, terpenes, minor cannabinoids, all preserved.

Flower rosin uses dried cannabis buds — accessible, but lower yields and more plant material contamination. Hash rosin starts from bubble hash, giving you a cleaner, more concentrated result. Live rosin starts from fresh-frozen plant material, preserving the full terpene profile that drying destroys. It's the cleanest, most flavorful expression of rosin — and the most expensive.

Rosin consistency ranges from sappy and translucent when fresh to a whipped, butter-like badder texture after processing. Temperature during pressing and post-processing determines final consistency.

Live resin is made from cannabis that's flash-frozen immediately after harvest — before any drying or curing. That matters because terpenes (the aromatic compounds responsible for flavor, effect, and entourage interactions) degrade significantly during the drying process. Freezing the plant immediately preserves the full terpene profile.

The frozen material is then extracted with a solvent — typically butane or propane — at very cold temperatures to minimize contamination. After extraction, the solvent is purged. Done properly, residual solvent levels should be well under legal limits (often a ceiling around 500 ppm for butane/propane, though exact limits vary by state). The result is a sauce-like, terpene-rich extract that's considered closer to the living plant than most BHO products.

Live resin is the gold standard of solvent-extracted concentrates. If you're going BHO, this is what you want.

BHO is the broad category covering most solvent-extracted cannabis concentrates. The names — shatter, wax, badder, sugar, crumble — all refer to texture and consistency, not fundamentally different products. They're the same basic extract processed differently.

Shatter is a hard, glass-like sheet — stable, easy to handle, made by not agitating the oil during purging. Wax and badder have been whipped or agitated, creating a soft, opaque consistency. Sugar has a wet, granular texture from partial crystallization. Crumble is dry and brittle, purged at higher temps or longer durations. Different textures suit different consumption methods and storage environments.

Quality varies enormously. BHO from a licensed producer using a closed-loop system and proper purging is a different product from anything made in an uncontrolled environment. Residual solvent is the main concern — reputable producers test for it.

Distillate is the most refined form of cannabis extract — a near-pure isolation of THC or CBD through a short-path distillation process. Everything else is removed: terpenes, waxes, lipids, minor cannabinoids. What remains is a clear, odorless, tasteless oil of extreme potency.

It's the most widely used extract in the commercial cannabis industry because it's consistent, shelf-stable, and easy to work with. It's what fills most vape cartridges. When terpenes are added back post-distillation (as they often are in cartridges), those are frequently botanical terpenes from other plants — not cannabis-derived.

The tradeoff: distillate loses the entourage effect. The minor cannabinoids and terpenes that modulate how THC feels are gone. Many experienced consumers find high-distillate products feel "thin" or "flat" compared to full-spectrum extracts. Higher potency doesn't equal better experience.

THCA diamonds are crystalline structures of nearly pure tetrahydrocannabinolic acid — the non-psychoactive precursor to THC. THCA becomes THC when heat is applied (decarboxylation). The diamonds form naturally when a high-quality extract is left to "crash out" over time, separating the cannabinoid crystals from the terpene-rich liquid around them — the "sauce."

Diamonds and sauce are often sold together. The diamonds provide extreme potency; the sauce provides flavor and the entourage modulation that pure crystalline THC lacks. Dabbing them together gives you the best of both — maximum cannabinoid delivery plus full terpene expression.

Diamonds alone, without sauce, are essentially the cannabis world's version of pure pharmaceutical THC. They're effective but experientially flat.

Isolate is exactly what it sounds like: a single cannabinoid, isolated to 99%+ purity. THC isolate is a white crystalline powder. CBD isolate is the same. No terpenes, no other cannabinoids, no flavor, no smell.

CBD isolate is widely available and legal in most of the US. It's commonly used in DIY formulations — tinctures, capsules, topicals — where precise dosing matters and you want zero THC. THC isolate is rarer and available primarily in legal cannabis markets.

The limitations are the same as distillate and diamonds: without the supporting cast of minor cannabinoids and terpenes, the entourage effect is absent. For therapeutic applications where you're targeting a specific cannabinoid mechanism, isolate is appropriate. For recreational use or whole-plant therapeutic applications, you're giving something up.

RSO is a thick, dark cannabis oil made by extracting the entire plant — flower, leaves, everything — in ethanol, then evaporating the solvent to leave a concentrated, full-spectrum oil. It looks like tar. It's not pretty. It's also not trying to be.

Rick Simpson began making and distributing it in the early 2000s after claiming it helped him treat his own skin cancer. That specific claim has never been validated in clinical trials, and RSO is not a proven cancer treatment. What it is: an extremely high-potency, full-spectrum cannabis extract used by medical patients for pain management, sleep, nausea, appetite stimulation, and other applications.

Because it's full-spectrum — meaning all the cannabinoids and much of the terpene content of the plant are preserved — RSO contains the complete entourage of compounds that more refined extracts strip out. That's either a feature or a bug depending on your goal. For patients seeking maximum therapeutic coverage, it's a feature.

RSO is exceptionally potent. A rice-grain-sized amount is a significant dose. It's typically consumed orally (under the tongue or in food) rather than dabbed, because the plant waxes and chlorophylls it contains would produce harsh, unpleasant vapor.
