Cannabis Concentrates

What are concentrates?

Concentrates, also known as hash, are a popular way of consuming cannabis. Concentrates are made through the process of stripping the marijuana plant matter of its psychoactive and cannabinoid resin properties (trichomes). The most popular and commonly known cannabinoids are THC, due to its psychoactive properties, and CBD, known for its therapeutic effects. That said cannabis contains over 66 cannabinoids, each with a unique set of properties and effects. During the extraction process, cannabinoids within the plant profile are extracted finding their way into the final product—hash. Plant material that is fresh at the time of extraction results in a higher quality hash.

Enjoying cannabis in the form of a concentrate allows consumers to receive a strong dose of cannabinoids without inhaling burnt plant matter. Concentrates continue to grow in popularity as more consumers look for an alternative to smoking marijuana.

How are concentrates extracted?

There are multiple ways to extract the trichomes from the marijuana plant matter. Most involve using a cold process to freeze the trichomes, allowing them to easily break off from the plant.

Ice Water Extraction

This process uses marijuana plant material, ice and water. Once blended, the trichomes fall off the plant and are sifted through pollen-extracting screens to remove the plant matter from the concentrate. This process yields “bubble hash,” or in circumstances where the concentrate is exceptionally high quality, it is considered to be a “full melt” product. Ice water extraction is typically thought to be the cleanest and safest way to extract hash, since no solvents or extreme heat are involved, thereby eliminating byproducts that could potentially cause impurities in the flavor and quality of the concentrate.

BHO (Butane Hash Oil)

This process of concentrate extraction uses cannabis plant material and butane as the solvent for extraction. BHO concentrate typically tests higher for concentrated cannabinoids than other forms of extraction. The extreme cold of the butane allows the trichomes to fall off the plant matter easily, breaking down the cell wall and creating a slab of trichomes.

The processor then removes the residual butane from the concentrate product using a closed-loop hash BHO machine, where a high percentage of the butane is recycled out of the product. Any remaining solvent gets removed during the purging process, when the slab of concentrate is baked in a low-temperature vacuum oven for a minimum of 12 hours. BHO extraction typically yields shatter, wax or live resin.

PHO (Propane Hash Oil)

Concentrates extracted with PHO are made exactly the same way as with the BHO process, except the processor uses propane as the solvent instead of butane.

CO2 Hash Oil

With this type of concentrate extraction, CO2 is used as the cold solvent. Since CO2 is not purged from the oil, it usually comes in a liquid form. This product is considered to be cleaner than BHO or PHO extracted concentrate because CO2 is not a combustible. This product is often more expensive than other forms of concentrate due to the expensive extraction process and limited market availability.
