Butane Hash Oil

Butane hash oil, or “BHO” for short, took the cannabis world by storm. Budder, buddha’s ear wax, crumble, pie crust, honeycomb, and sap are names given to describe different textures and consistencies of concentrate. Different levels of moisture and agitation will produce waxes of different textures and consistencies. Weed scientists quickly tweaked the process a thousand different ways to produce hash oils of different textures and consistencies. BHO is created by blasting pure butane through ground cannabis plant matter, extracting just the cannabinoids like THC, terpenes, and flavonoids. Cannabinoids like THC are responsible for the psychoactive effects of cannabis while terpenes provide most of the flavors and smells associated with concentrates. Separating the oils from the plant allows the user to consume higher percentages of THC in smaller doses. The major downfall of BHO is the potential presence of residual solvents in the final product. Trace amounts of butane left behind can irritate the lungs and cause potential health problems long term. Other non-toxic solvents may provide a healthier alternative.

Propane Concentrates

Propane extraction produces a similar end product to butane although propane concentrates tend to be soft and buttery in consistency. The process for producing propane hash is similar to butane, though propane evaporates at lower temperatures resulting in a smoother texture. Propane solvents preserve different levels of terpenes than butane hash which means that the same weed processed both ways will result in different flavors. For this reason, many concentrate manufacturers use a combination of propane and butane for extraction to preserve more of the true terpenes.

Live Resin

Live Resin is made the exact same way as BHO except that it’s made with fresh flowers that are promptly frozen after harvest, to retain their terpenes. The cannabis buds are kept frozen throughout the entire extraction process. Live resin is extracted in labs with specialized extraction tools. Through a process of chilling butane, while passing it through the frozen cannabis buds, the trichomes maintain their structure, making it easier to remove the butane from the solution and purify the concentrate. The final step in the process uses water to warm the extraction, evaporating any residual solvent. The final product is an extremely pungent and flavorful wax that will tingle your nose and titillate your senses while you take a dab.

Terp Sauce

Terp sauce is a new type of BHO product that is extracted to preserve the full spectrum of cannabinoids and terpenes. Terp sauce has an incredibly high potency due to the “entourage effect,” an increased high caused by ideal combinations of cannabinoids and terpenes. Terp sauce contains crystals of undissolved THC-A which when dabbed convert to THC for even more intensity.

CO2 Oil

Liquid CO2 is a non-toxic solvent used to extract cannabinoids like THC and CBD, and terpenes from cannabis plants. CO2 oil is made by exposing the bud to Liquid CO2 under extremely high pressure. The extraction process preserves fewer terpenes than BHO resulting in a less pungent taste-making CO2 oil an excellent option for making edibles. Although CO2 oil tends to be less potent than butane hash oil, CO2 solvent evaporates entirely from the finished product, reducing the risk of inhaling any residual solvent. CO2 oil is the concentrate most commonly used to fill vape pens. Although this extract is less flavorful than BHO, CO2 oil manufacturers can reintegrate the original terpene profiles into the finished product giving the vaped oil a more satisfying flavor.

Alcohol-based Concentrates

Alcohol is a solvent most commonly used in the production of tinctures. Tinctures are popular among medical users for the potency and convenience. Tinctures can be taken orally, or added to beverages and cooked food. Alcohol tinctures are made by soaking decarboxylated ground weed in ethanol to infuse the alcohol with THC. Isopropyl alcohol can also be used to extract hash oil from ground cannabis. After soaking the Cannabis in alcohol, the liquid is filtered removing plant material and all solids. Next, heat is applied to purge the alcohol. The major difficulty with alcohol extraction is preventing the bitter tasting chlorophyll from being dissolved into the concentrate along with the cannabinoids and terpenes. This can be achieved in a lab by carefully regulating the temperature and pressure during the purge. Alcohol-based concentrates are quite safe to use as all of the primary alcohol can be purged from the final product. RSO (Rick Simpson Oil) is popular at home extraction method, famous for its medicinal properties.

THC-A Crystalline

THC-A Crystalline is the purest form of THC-A extraction, coming in at 99.997% pure. These cannabis crystals closely resemble other high potency drugs, but only in their looks. It’s colorless, flavorless, and lacking in the flavorful terpenes that cannabis concentrates usually contain. THC-A is the non-carboxylated form of THC, meaning the psychoactive properties have not been activated in these crystals. In its pure, unheated form, it won’t get you high, but if you were to take a dab you may reach new heights, that would surprise even the most expert dabbers.

Solvent-less Cannabis Concentrates

Until recently the options for solvent-free extracts were slim. Kief, bubble hash and old school pressed hash were the only concentrates on the rolling tray that didn’t contain the Butane or CO2 in the extraction. One day, a bright household cannabis scientist placed a few nugs onto wax paper and pressed them in their mom’s hair straightening iron, and rosin was born. At least this is how I imagine it happened. The discovery of pressed rosin changed the game for the solvent-less concentrates market. The ability to create stable rosin from plant matter and heat opened the door for new products to be imagined, and new concentrates to dab with.

Kief

The yellow-green powder at the bottom of your grinder is called kief. Those tiny particles of trichomes contain high levels of terpenes and THC. Kief is essentially the basis of every hash and concentrate, this is the extracted plant material before it gets processed.Try sprinkling kief, the most basic form of a concentrate, on top of a bowl pack or throughout a joint or for an extra potent punch. Roll your joints and nugs in oil and powder them with kief (also known as cannabis caviar) for twaxed joints and or moonrocks, respectively. Prepare yourself to blast off. Try pressing your kief with a straightening iron to make your removepure mely rosin, or even add it to your cannabutter. If you want to collect larger amounts of kief, separate it from your bud with a process known as dry sifting. Using silkscreen materials, kief can be manually extracted in a larger scale with manual agitation. By stacking 3-4 different sized mesh screens, you’ll be able to separate the kief from the finest particles or plant material. The highest quality of dry sift is called “full melt”.

Ice Hash

Ice Hash is created using a process of separating trichomes from buds by freezing them, soaking them in ice water and agitating them manually with screened “bubble bags”. For this reason, Ice hash is also known as bubble hash. This arduous process yields a pure hash that is solvent free. Full-Melt Ice hash will melt down into a golden liquid known as ice wax.

Rosin Press

The first rosin press began with an at home experiment with parchment paper and a hair straightener, it’s true, even larger quantities of rosin were produced using a modified tee shirt press. Heat and pressure are all you need to extract rosin from your cannabis buds. This process yields a yellow honey-like substance that can be used by dabbing. Professional extractors use high-pressure presses to remove large quantities of rosin from each nug.
