Butane Hash Oil or C02 Hash Oil?

In the present times, a large majority of marijuana smokers are shifting from the conventional dried and crushed form used in joints, to the purer form usually known as concentrates. More often than not, concentrates are obtained through a meticulously formulated extraction process. Not only are these concentrates highly potent, but also take a lot lesser time to cause the desired effect.
The extraction process for cannabis concentrates requires the resin of the marijuana to be extracted from the leaves as well as the buds of the plant. The extraction process makes use of the various solvents, the most well-known of which are the butane, and carbon dioxide.

Butane Hash Oil (BHO)

The concentrates prepared using butane is known as Butane Hash Oil or BHO. In this case, cannabis trimmings are cleared through butane in a container which is airtight. Here, the trimmings remain intact, while the resin of marijuana is forced out in a way that it gets mixed with the butane.
While the preparation of BHO is comparatively easier, the product is rather controversial. Given that a chemical solvent is used to formulate the concentrate, its effect on the overall health of the patient is uncertain. Moreover, butane is essentially a combustible gas, which makes its unsupervised use, susceptible to various hazards.

CO2 Hash Oil

As in the case BHO, CO2 Hash Oil gets its name from its solvent carbon dioxide. The extraction of cannabis through liquefied carbon dioxide is a rather complex process. Known as Supercritical Fluid Extraction (SCFE), this process has the benefit of getting rid of molds, mildews and other contaminants that are usually found in concentrated Santa Barbara Cannabis
. In this process, oil is obtained through passing liquefied CO2 through marijuana buds under extremely high pressure, after which cannabis sugar trim is obtained.
Given that CO2 is an inert gas, and the process of extraction does not involve any combustible gas, CO2 Hash oil is usually preferred over its counterpart created using Butane.


While the extraction of Cannabis though CO2 is preferable due to the fact that it is safer, both with respect to its processing as well as in terms of the effect that it has on the human body, due to the absence of any unwanted chemicals. As a matter of fact, the cannabinoids and terpenes are completely removed from the marijuana buds in case of C02 hash oil, while In addition BHO is known to leave traces of heavy metal, even after the complete evaporation of butane.
However, the procedure of extraction of Cannabis using CO2 requires sophisticated machinery, which adds to the cost of its production. Moreover, the skill set required to produce CO2 hash oil is quite specialized, thus creating a need for workers with a higher pay scale. It is due to this fact that CO2 hash oil isn’t as readily available as CO2 hash oil.

Both the types of Hash Oil contain a high content of THC, ranging anywhere from 50% to 75%.
