Hash Oil – an overview

Hash Oil

Hash oil is a concentrated cannabis extract that can be smoked, vaped, eaten, or rubbed onto the skin. The use of hash oil is sometimes called “dabbing” or “burning.”

Hash oil comes from cannabis plants and contains THC (delta-9-tetrahydrocannabinol), the same active ingredient as other marijuana products.

But hash oil is more potent, containing up to 90 percentTrusted Source THC. By contrast, in other cannabis plant products, the average THC level is approximately 12 percentTrusted Source.

Read on to find out more about hash oil and other marijuana concentrates, including uses, benefits, and risks.

About marijuana concentrates

Marijuana concentrates, including hash oil, are potent extracts from cannabis plants. The products available vary in form. The table below outlines some common forms of hash oil.

NamesFormConsistencyTHC Level

butane hash oil (BHO), butane honey oil, honey oilliquidgooey70 to 85 percent

Most of the items listed above range in color from golden to amber to dark brown. They may be translucent or opaque.

Due to their potency, concentrates are often sold in small quantities, and may cost more relative to other marijuana products.

Hash Oil


The potential benefits of hash oil are similar to those associated with marijuana. Hash oil may trigger a sense of euphoria and help to treat nausea, pain, and inflammation.

Since hash oil is more potent than other forms of marijuana, its effects tend to be stronger as well. As a result, it may provide greater symptom relief for people who use marijuana to treat medical conditions, such as chronic pain or cancer.

More research is needed to understand the unique benefits of hash oil and related products.

Types Of Cannabis Resin Products

There are several types of resin products. Some of the most common include:


This traditional cannabis concentrate has been used for many decades. When consumed, a hash can provide a feeling of euphoria. It is made by separating trichome crystals before rolling the substance into a ball or pressing it into a brick.

Butane Hash Oil

Abbreviated as BHO, butane hash oil is one of the most popular forms of cannabis concentrate. It is commonly used in dabs due to its potency and fast onset. BHO is made through the process of removing fatty trichome resin glands from the cannabis plant with butane.

Live Resin

Live resin is made from cannabis plants that have been flash-frozen immediately post-harvest. By freezing directly after harvest, terpenes and other cannabis compounds do not have the chance to degrade.


Rosin does not require solvents and is made by applying pressure and heat to dried cannabis plants.

CO2 Oil

CO2 oil is a type of cannabis concentrate derived from cannabis resin that has been extracted from a plant with a solvent. However, instead of using butane like hash oil, CO2 is used.

How To Smoke Resin

How you smoke cannabis resin will depend on the type of product you purchased. Hash oil concentrates are typically sold in oil cartridges that can be attached to a smoking device. Other concentrates, such as rosin or “dabs,” are best enjoyed with a rig or dab pipe. The simplest way to ensure that you use up all of the resin in your bong or pipe is to apply heat to the outer surface. As the resin evaporates, you can inhale the vapors.

Shop Cannabis Resin

When shopping for cannabis concentrates, you are likely to come across resin. Resin delivers many of the same benefits as other concentrates. To learn more about resins or to shop our selection of cannabis concentrates, contact Pure Oasis.

Effects of BHO

There is no safe level of drug use. Use of any drug always carries some risk. It’s important to be careful when taking any type of drug.

Butane hash oil affects every individual differently. Even the same person may have a different experience on separate occasions or over the course of their life. Some of the factors that influence these differences appear to be: 

Hash Oil
  • size, weight and health
  • whether the person is used to taking it
  • whether other drugs are taken around the same time
  • the amount taken
  • the strength of the drug
  • expectations of consuming cannabis
  • the environment of the individual
  • the individual’s personality.

Low to moderate use of cannabis may produce the following effects:

  • feelings of relaxation and euphoria
  • spontaneous laughter and excitement
  • increased sociability
  • increased appetite
  • dry mouth.

High strength cannabis in the form of butane hash oil may produce the following effects:

  • relaxation
  • reduced nausea
  • changes to heart rate and blood pressure
  • Pain relief
  • excitement and restlessness
  • confusion and paranoia
  • anxiety and panic
  • reduced attention rate
  • decreased reaction times
  • detachment from reality

Long term effects

Long-term effects are dependent on how much and how often the cannabis is consumed and may also be affected by how the cannabis is consumed (e.g. vaporising a concentrate versus smoking the flower). Heavy, regular use of cannabis may eventually cause: 

  • tolerance to the effects of cannabis
  • dependence on cannabis
  • reduced cognitive functioning

Side effects

The side effects of hash oil are similar to those associated with marijuana. However, since hash oil is more potent than marijuana plant products, the side effects may be more severe.

Short-term side effects may include:

  • altered perception
  • changes in mood
  • impaired movement
  • impaired cognition
  • impaired memory
  • dizziness and fainting
  • anxiety and paranoia
  • hallucinations
  • psychosis
  • cannabinoid hyperemesis syndrome (CHS)
  • dependence

More research is needed to understand both the short- and long-term side effects of hash oil use.


There are a variety of ways people use hash oil.

Dabbing refers to the use of a special pipe to heat and vaporize hash oil. Sometimes called an “oil rig” or a “rig,” this apparatus consists of a water pipe with a hollow “nail” that fits into the pipe’s gauge. Alternatively, some people use a small metal plate called a “swing.”

The nail or swing is typically heated with a small blowtorch before a small amount of hash oil is applied to its surface with a dabber. With the heat, the hash oil vaporizes and is inhaled through the pipe, and it’s usually inhaled in a single breath.

This method is more dangerous than other methods because of the blowtorch, which poses a risk of burns.

Hash oil can also be smoked, vaporized, ingested, or applied to the skin.


Hash oil, and especially illegal hash oil, poses unique risks. Some of these include:

Safety. There are few studies available documenting the risks of hash oil. As a result, we don’t know for sure whether it’s actually safe to use, and if so, how often and at what dose.

Potency. Hash oil is four to five times more potent than regular marijuana. As a result, it may be more likely to cause a strong high and undesirable side effects, especially among first-time users.

Tolerance. Since hash oil contains so much THC, it could increase your tolerance to regular marijuana.

Burn risk. Dabbing involves the use of a small blowtorch. Using a blowtorch, especially when you are high, could result in burns.

Chemical impurities. Illegal hash oil is unregulated, and may contain dangerous levels of butane or other chemicals.

Lung injuries. A 2019 case studyTrusted Source suggested a potential link between the use of a dabbing apparatus and lung symptoms similar to those of pneumonia.

Cancer risk. A 2017 study reported that the vapors produced by dabbing contain carcinogenic substances.
