Cannabis comes in many forms, several of which you can find at dispensaries in Denver, Colorado. One form is cannabis oil.

Like other types of plant-based oil, cannabis is extracted and purified to create a new product with stronger effects. In the case of cannabis, oil is refined in certified laboratories to concentrate cannabinoids, chemicals that naturally occur in cannabis plants. Cannabidiol (CBD) and tetrahydrocannabinol (THC) are two cannabinoids producers seek to concentrate. The percentage of CBD and THC vary by plant, as growers breed plants to get specific mixtures.

There are many different types of cannabis oil, each identified by its plant of origin, cannabinoid content, and uses. One oil that’s made a huge impact on the industry is Rick Simpson oil, also called RSO. Many people claim to experience the benefits of RSO, but what does the scientific data say? Let’s take a look.


Since 2003, Rick Simpson has provided RSO-making instructions. These efforts to make cannabis more widely available made him a well-known figure in medical marijuana activism. He started his efforts when he couldn’t find relief from pharmaceuticals after a fall.

Today, numerous dispensaries, including those in Denver, CO, sell RSO. Many consumers claim Rick Simpson’s oil benefits have improved their well-being.


What exactly is RSO, and how is it different from other cannabis oils? For starters, it has much higher levels of THC, which is the cannabinoid responsible for the “high” feeling partakers get.

Which effects arise and their intensity depends on the strain and how much individuals have. RSO is usually made with Indica strains, purported to have relaxing effects.


One of the reasons cannabis oil is so popular is because you can use it in a variety of ways. For example, you can apply it topically. Individuals do so by putting a small amount on the area they want to affect and rubbing it into the skin.

The topical application targets cannabinoid receptors in the skin, so people seeking pain relief or skin care results generally use this method. Since the THC isn’t processed through the digestive system or absorbed into the bloodstream, this method doesn’t induce psychoactive effects (feeling high).

People seeking more general benefits of RSO usually take it orally. The oil does have a taste, which you can mask by adding it to food and drink. However, taking it this way means you have to wait about an hour for it to take effect. The fastest way to experience results is by placing RSO oil under your tongue, where mucus membranes are located. These mucus membranes absorb the oil, cutting the wait time in half as the THC hits the bloodstream directly.


There are many claims about the benefits of RSO, but what can it actually do? There are anecdotal and scattered medical reports that THC can help patients in their fight against cancer. However, more rigorous studies must be done on the topic.

That said, there is some support for the following benefits of RSO:

  • Reducing nausea
  • Reducing swelling
  • Boosting mood
  • Moisturizing skin
  • Increasing appetite
  • Decreasing body discomfort


If RSO sounds right for you, where can you get it? Rick Simpson is a big supporter of making your own at home, but risks are associated with this.

Extraction involves separating specific chemical compounds from the rest of the plant. There are several ways to do so:

  • Propane and butane extraction
  • Alcohol extraction
  • CO2 extraction

You need special equipment for each of these methods, and you need a large quantity of cannabis. This creates an unnecessary cost for most people.

Additionally, you must carefully follow safety procedures when extracting THC, as the solvents are flammable and may be under extreme pressure. Finally, if certain solvents aren’t properly filtered out, they can be toxic.


It’s much safer and more affordable to get RSO at your local dispensary. Cannabis product manufacturers employ labs with the necessary equipment to extract THC, and these laboratories are held to incredibly high standards. They must adhere to safety regulations and test products to ensure they don’t contain toxic chemicals.


How you use RSO is up to you. Since there are so many ways to take cannabis oil, you can experiment until you find one that works.
