Rick simpson oil: everything you need to know

If you have decided to open this article, you are part of that group of curious people who would like to know more about Rick Simpson oil.

Many have wondered whether it is a beneficial product and, more importantly, whether its presence of THC makes it dangerous.

So, how do things stand?

In this article, we will try to understand what RSO is, how it is produced and its potential benefits.

Do you already have the impression that this article is for you?

Let’s get started!

What the RSO is

Let’s cut to the chase: what is RSO?

Simply put, RSO is an oil derived from cannabis, which contains all the cannabinoids, terpenes and additional compounds of the entire plant.

The extraction process is complex and rather lengthy. However, similar to the preparation of a tincture, the colour is typically close to black, and the taste is not exceptional due to the high amount of plant matter.

RSO recipes typically call for high-THC, indica-dominant cannabis (although CBD-rich options do exist). THC binds to the CB1 receptors of the endocannabinoid system, most of which are concentrated in the brain and nerve cells, and when this occurs, it appears to play a significant role in decreasing chronic pain.

RSO has been created as a therapeutic drug for cancer and other chronic health conditions, such as multiple sclerosis and asthma.

Although Rick Simpson no longer produces the oil himself, it remains a key ingredient in treatment plans for patients across North America.

Yes, that’s right, Rick Simpson.

But who is this person after whom the oil is named?

The story of Rick Simpson

Rick Simpson did not want to become a marijuana icon.

He was a Canadian engineer working in a hospital in 1997, assigned to work on some asbestos-covered pipes inside a boiler. Poor ventilation and toxic fumes caused him to faint and fall down the stairs.

Soon afterwards, he developed tinnitus and dizziness, and no prescribed medication seemed to help him. Despite his illegality and against his doctor’s advice, Simpson began using medical marijuana, which immediately proved to be very beneficial and able to alleviate his symptoms.

In 2003, he was diagnosed with basal cell carcinoma, a type of skin cancer.

By then, Canada had legalized cannabis for medicinal purposes, but Simpson had difficulty finding a doctor who supported its use. Simpson always claimed that applying RSO to the skin and leaving it bandaged for four days cured cancer, although this has not been scientifically verified.

From then on, he began mass-producing the oil and distributing it free of charge to thousands of patients. Then, in 2009, his property was raided by the Royal Canadian Mounted Police, and thousands of cannabis plants were confiscated.

To escape legal persecution, Simpson now lives in Croatia and runs a website for his RSO recipe, dosage guide and books.

He suffered a stroke in 2018 and has since retired from public life, but he continues to advocate for RSO and medical cannabis.

The benefits of RSO

Despite Rick Simpson’s near-miraculous recovery from cancer and tinnitus, the scientific community has no research to back up these claims.

There have, however, been promising reports attesting to the efficacy of RSO, such as a 2013 article demonstrating that its use significantly reduced leukaemia cells in a 14-year-old terminal patient with no toxic side effects.

In addition, RSO has helped patients manage conditions such as:

  • multiple sclerosis;
  • epilepsy;
  • cancer;
  • insomnia;
  • chronic pain;
  • asthma.

As an incredibly potent THC product, RSO offers potential therapeutic effects, such as pain relief and appetite stimulation, and may help with sleep and nausea. But since no studies have been conducted, we cannot guarantee that RSO provides these benefits.

Despite the high concentration of THC, no amount of this oil can cause overdose, death, or lasting side effects. However, the risks associated with taking RSO are the same as those related to taking a high dose of any cannabis product, such as an edible, concentrate or a more significant amount than prescribed.

In short, there is no need to worry.

A 2021 study indicated that although many cancer patients use cannabis with cancer treatments, their primary care teams have not figured out how to integrate cannabis into a regimen.

Much more research needs to be done on how best to use RSO to amplify treatment.

Finally, among other possible benefits, RSO may help alleviate back pain.

Indeed, one of the most common uses of RSO—and cannabis in general—is for chronic pain. Back pain is one of the most common forms of physical pain, with as many as 80% of people experiencing it at some point in their lives.
