Cannabis Concentrates

What are concentrates?

Concentrates—also known as hash—are a popular way to consume cannabis. Concentrates are created by stripping the marijuana plant matter of its psychoactive and medicinal cannabinoid resin properties, also known as trichomes. The most popular and well-known cannabinoids are THC for its psychoactive properties, and CBD for its medicinal properties, however marijuana contains at least 66 cannabinoids. Typically, all of the cannabinoids that are in the plant’s profile are extracted and end up in the hash during the concentrate extraction process. The fresher the plant material when it is extracted, the higher the quality of the resulting hash.

Consuming marijuana in a concentrated form allows users to receive a stronger dose of cannabinoids while avoiding inhaling burning plant matter. Concentrates are growing in popularity as more consumers are recognizing the benefits of cannabis, but weary of the side effects of 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.
