The Master List of Hash and Cannabis Terminology

Updated: May 25

This will be a working list because attempting to conquer it at once has prevented me from starting the project. This way I can simply add to it as I go. Don't take it too seriously.

Open to interpretation and almost always up for discussion. No fixed definitions and regional and cultural influence may apply. Leave comments or drop a term on the Forum, anywhere I'll see it, and I will add the appropriate ones to the list.


A word that only a true "custy" would know to use.

Cannabis Concentrates: Terminology and Concepts

Hash, Hashish-

Concentrated Cannabis made without the use of chemical solvents. Solvents rupture trichome glands to extract molecules from inside the trichome gland, while hash removes trichomes. Hash has become a catchall term for concentrates, although it is more appropriate for solventless products alone.

Solventless methods differ entirely by sieving or removing trichome glands from the surface of the plant and preserving them. I use hash for all solventless varieties originating from an ice water process or other method of mechanical separation. Fancy talk for shaking weed around and collecting the trichomes falling off. And or pressing collected trichomes into a more traditional hashish (dried cannabis flowers) or live rosin (freshly frozen flowers). Hash is a process of refinement and preservation that does not extract but removes trichomes from the surface of cannabis material.

  • Ice-Water Hash-

Hashish made from Cannabis that's frozen moments after harvest. Ice Water hash is graded from one to six stars. Only five and six star quality ice water hash is capable of being "dabbed" alone.

  • Bubble Hashish-

Made the same way in ice and water, but with dried Cannabis flowers.

Solventless-(see Hash)

Hash made the way it was meant. Solventless uses ice and water or other methods to concentrate cannabis without chemical solvents. Not to be confused with Solvent-Free, solventless hash and or rosin products, remove and preserve trichomes naturally.

Rosin- (all consistencies here)

A process that uses pressure and heat to remove cannabinoids and terpenes from cannabis. Hydraulic or pneumatic presses are used to squeeze cannabis flowers or hashish into a dabbable concentrate. Lots of varieties of rosin exist as explained in full detail here.

Live Rosin-(see rosin)

Live rosin, much like live resin, uses fresh-frozen cannabis flowers to begin with. It also becomes a live rosin when ice water hash is pressed, rather than pressing whole cannabis flowers.

Flower Rosin-(see rosin)

Flower rosin uses the same process, hydraulic or pneumatic pressure to squeeze the contents directly from cannabis flower material.

Cold Cure Rosin or Rosin Badder-(see rosin)

Rosin is left to sit or cure, and whipped or stirred to make fresh press rosin into a rosin badder.

Rosin Sauce, Jam, (Jar-Tech)- (see rosin)

Rosin badder that uses pressure, heat, and time to allow terpenes to naturally separate from THC-A, which crystalizes. The final texture of rosin sauce can be full of micro-crystallization, mimicking the texture of a chemical extract like live resin.

BHO or Chemical Solvent Extractions

These products sold and marketed responsibly, will pride themselves on transparency. They will readily reveal their style of technology and be happy to call it BHO to distinguish it from hash. Due to the solvents dissolving trichome glands from the plant, it becomes a process of extraction, rather than solventless refinement. There's a list of different solvents used, such as Butane, Propane, Hexane, Ethanol, and more. They can all be labeled as BHO or hydrocarbon extractions.

Hydrocarbon Extractions

Hydrocarbon extracts are a great way to make use of leftover trim material or cannabis flower that refuses to produce in ice water hash. Most of these extracts use similar chemical processes as major consumer brands, who extract and concentrate nutrients, vitamins, minerals, and essential oils from organic material. Problem is cannabis doesn't work the way large producers had hoped.

The recreational and therapeutic effects of cannabis are not caused by the THC molecule alone, throwing a serious kink in the plans of chemical industries. Thank You Hash Gods. In fact, the chemical solvents used destroy hundreds if not thousands of cannabinoids and terpenes that lead to maximum results, aka The Entourage Effect, when present. An affordable method of extraction, but one that cannot compare with solventless methods.

Solvent-Free- (see BHO)

Here we go with the market manipulation. Often used to describe cold-pressed CO2 extractions. Solvent-free is anything but. Solvent-free uses chemical solvents but purges them 100% clean from the final product. Problem is, we aren't worried about leftover or residual solvents as much as we are concerned with cannabinoids and terpene content. While solvent-free may be 100% clean of residual solvents, it doesn't change the fact that trichome glands were ruptured and dissolved in the process of collection. Furthermore, solvents and rupturing trichome glands cause volatile terpenes to off-gas and be missing from the final product.

Distillate-(see also BHO)

A distillate uses the process of distillation, not unique to cannabis, to not only extract cannabinoids from inside cannabis trichomes, but to isolate single cannabinoid molecules, namely THC or CBD. As is the case for all chemical extractions, they remove cannabinoids from inside each trichome gland growing on the surface of the cannabis plant. Distillation provides an isolated distillate, containing pure THC, used widely across the industry.

Distillates provide only one of over 200 cannabinoids, and depletes the product of all terpenes. It's an economic way to remove THC from cannabis byproduct, trim, waste, etc., but provides the least effective results of any cannabis product.

CBD Extractions

Right now, they're running with this CBD thing after decades of propaganda in support of the single molecule (read above on hydrocarbon). It's the latest molecule to be exploited for all its worth, as the cure-all, despite evidence of THC-A's necessary interaction. They fail to distinguish CBD made from hemp, that lacks even minimal traces of THC proven to aid dramatically in the absorption and efficacy of CBD .

Yes, CBD is highly beneficial, that is not where my gripe lies, but CBD alone cannot compare to the medicinal value of CBD in combination with THC and hundreds of terpenes and cannabinoids. Furthermore, whether it comes from cannabis or hemp is too often ignored. I support one company for CBD products. Ask me and I'll tell.


Can be made with or without the use of chemical solvents. Mixed, whipped, or stirred BHO or Solventless Rosin.


6 star Ice Water Hash that has full melt-ability for clean and functional dabbing. Rated from one to six stars, Full-Melt hash is considered technically to be six-star hash. Dabbed at the proper temperature it will leave almost no residue behind. A slight char is all that will remain after dabbing full melt on quartz.

"Buddered" or "Cured" Rosin

Buddered, buttered, cured, or Dry rosin. Rosin is pressed clear, but turns to an opaque solid once removed from cold storage. This process is readily apparent ,as clear rosin will completely changes texture and appearance. It will often marbleize, get milky, and turn to a solid.


This is the worst thing that can happen to ice water hash. Similar to rosin, Ice water Hash can become dried up and turned into a hardened and "caked" consistency. There's no coming back as many terpenes will have dissipated. It's still fine for consumption, but is missing much of what sets ice water hash apart to begin with.

Growing Terminology and Concepts


noun: landrace; plural noun: landraces

  1. a local cultivar or animal breed that has been improved by traditional agricultural methods.

Landrace "strains", more appropriately called cultivars, are cultivars growing naturally without influence or human selection. In this day and age, landrace cultivars are nearly impossible to locate, if any exist at all. Only a handful of places on Earth had landrace genetics free from outside influence. These landrace strains have evolved to survive whatever conditions or environments they have grown in. All of today's modern genetics combine numerous Landrace genetics.

Strain/Cultivar/Variety (genetic)

noun: cultivar; plural noun: cultivars

  1. a plant variety that has been produced in cultivation by selective breeding. Cultivars are usually designated in the style Taxus baccata “Variegata.”.

Strain never sat well with the big bosses and is a term leftover from black market ideas. More aptly titled cultivar, a cultivar is the specific genetic of cannabis plant. It is the specific variety of cannabis such as, "Blue Dream" or "Purple Haze". For the young bloods, "Papaya" or "GMO" are two different varieties or cultivars .


noun: phenotype; plural noun: phenotypes

  1. the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.

Each of our genetic cultivars makes up specific phenotypes. The phenotype is often labeled with a number such as "Papaya #35". Papaya is the genetic or the cultivar and it is the 35th phenotype.

This is where pheno hunting comes in. Having ten Papaya seeds, each one will become a different phenotype. Not all seeds from the same cultivar or genetic will produce the desired characteristics in its environmental settings. These types of specifics were largely out of play to the consumer until solventless hash making took off. With the extremely low yields of ice water refinement, selecting ideal phenotypes can make or break solventless success.

Trichomes are what we harvest for ice water hash. There are three different types of cannabis trichomes:

Bulbous trichomes are tiny bulbs that dot the surface of the plant. They cannot be seen without a microscope and their production of cannabinoids is still in question. They add a sheen to the cannabis plant and add to the stickiness of the flower. Bulbous trichomes are distributed throughout the entire surface of the plant.

Capitate-sessile trichomes are more abundant than bulbous trichomes, but still typically only visible with a microscope. Like bulbous trichomes, capitate-sessile trichomes have large bulbs, but with more of a classic mushroom-shaped structure. This trichome is primarily found on the underside of sugar and fan leaves.

Capitate-stalked trichomes are the ones we're after. Shaped like mushrooms and containing a large bulb or "head" at the top of a stalk. These are the largest and most abundant trichomes on cannabis, (yes!) and most familiar to consumers. The capitate-stalked trichomes are primarily found on the surface of cannabis flowers and are rarely seen on fan leaves or stems.

Vintage Variation

The different batches of the same cannabis genetic or variety can be attributed to vintage variations, where each batch is slightly different and especially across different growing styles and locations. Batches grown outdoors are influenced by nature and weather patterns. With modern hashish we are able to really key-in and taste the dynamic flavors and nuanced changes from one batch to another. With the same producers, we should be able to notice slight changes in the same genetic from year to year.
