Cannabis Oil

Cannabis oils are highly concentrated extracts, they are usually made by adding cannabis plant material to a solvent, after the solvent has extracted the cannabinoids from the plant material the solvent is then evaporated away leaving behind the extracted concentrated cannabinoid oil. Here is a brief guide to the different forms

BHO: Butane Honey Oil

This is extracted using butane gas. Butane has a low boiling point of 0.5 °C (31.1 °F) and using butane is very dangerous and it must always be performed outdoors. There have been many instances of fires caused by people using butane as an extraction solvent and some fire departments in the U.S. have gone so far as to issue warnings against its use. There are many companies who sell ready made Butane gas extraction kits and they are readily available online. The best advice we can give is to not attempt this extraction process, if you decide to do so then wear protective clothing and always carry out the procedure outdoors away from any flame source.

   
These injuries were sustained attempting to make Butane extracted honey oil. The individuals cotton sports pants caught fire and injuries to the legs and groin area were extensive with serious burns to the penis and testicles, his hair caught fire and he sustained severe burns to the scalp and face resulting in noticeable scarring. Butane is a highly volatile gas and should never be used to extract cannabis oil for medical use, it is far too dangerous. Injury from Butane gas extraction

QWISO

This refers to Quick Wash Isopropyl, which literally means a ‘quick wash’ in Isopropyl alcohol, the cannabis is typically in the alcohol for under a minute, this method can produce a very high quality oil.

FECO

Full Extract Cannabis Oil, differs from QWISO as the cannabis has more of a soak than a wash, FECO fans often use Everclear® a 190° proof Grain Alcohol. It produces a very good quality oil.


Everclear grain alcohol

Everclear grain alcohol, is the brand name of a colorless, unflavored, distilled beverage sold in some states in the U.S. and bottled at two different high strengths: 151-proof and 190-proof, meaning respectively 75.5% and 95% alcohol by volume, 190-proof spirits are the strongest that are available and they are ideal for this basic method of making cannabis oil. It is illegal to sell 190-proof Everclear in California, Florida, Hawaii, Iowa, Maine, Massachusetts, Minnesota, Nevada, New Hampshire, North Carolina and Virginia. It can be purchased in Ohio but only under severe restrictions. In Canada, Everclear is sold in the province of Alberta but not in other provinces. In British Columbia, it is available for purchase only with a permit for medical, research, or industrial use. Everclear is difficult to obtain in the E.U, it is however possible to distill your own solvent.
 

Hemp seed oil

This is usually referred to as ‘Cold pressed hemp oil’ and is made by ‘pressing’ non psychoactive cannabis hemp seeds, the extracted oil is very healthy and nutritious but it is not suitable for curing medical conditions as the seeds do not contain cannabinoids.

Cannabis Oil Infusion

Infused oil differs from an extracted oil in that it's not as concentrated; but Hemp or Olive oil infused with cannabis makes a versatile edible

Rick Simpson Oil

RSO refers to the oil promoted as a cure by cancer sufferer Rick Simpson, it is made by extracting cannabinoids by the use of a solvent, such oils are high in cannabinoid content. The use of the name ‘Hemp Oil’ to describe this extraction is confusing to say the least (see below). Rick’s process and instructional videos are available on his site www.phoenixtears.ca

Solvents commonly used to make cannabis oil

With all extraction methods, extreme caution must be taken when using solvents.

Naptha (boiling point between 30 °C and 200 °C).

Naptha is extremely volatile and can explode on exposure to high temperature so great care must be taken when it is used. Naptha is recommended by Rick Simpson, however there are concerns expressed by some that naphtha can be carcinogenic. Some commonly available forms of Naptha contain impurities which may also have harmful properties of their own.

Acetone Boiling point 57 °C (135 °F).

Easily available as a solvent and degreaser, Acetone evaporates rapidly and it is a popular solvent and is recognized to have low acute and chronic toxicity if ingested and/or inhaled. Acetone has been internationally rated as a GRAS (Generally Recognized as Safe) substance for food use and is produced and disposed of in the human body through normal metabolic processes. The most hazardous property of acetone is its extreme flammability. At temperatures greater than acetone's flash point of -20 °C (-4 °F), air mixtures of between 2.5% and 12.8% acetone, by volume, may explode or cause a flash fire. Vapors can flow along surfaces to distant ignition sources and flash back.
