Rick Simpson Oil (RSO) is a potent, full-extract cannabis oil made famous for its high THC content and therapeutic reputation among patients and researchers alike.
Introduction: What Exactly Is RSO?
If you’ve been researching cannabis oils, you’ve probably come across the name Rick Simpson Oil, or simply RSO. Known for its deep amber color and thick, sticky texture, RSO is one of the most concentrated forms of cannabis extract available today. It was created by Rick Simpson, a Canadian engineer who used it on his own skin condition and later shared his process with the world through his website phoenixtears.ca.
Unlike typical CBD oils you might find at a health store, RSO is high in THC, the psychoactive compound in cannabis. That means it can produce strong effects and should always be used carefully and responsibly.
The Story Behind Rick Simpson Oil
Rick Simpson’s story began in the early 2000s. After a workplace accident exposed him to toxic fumes, he experienced chronic health issues and later discovered cannabis could help him recover. When he developed skin spots that doctors struggled to treat, he applied a homemade cannabis extract topically—and according to his own account, saw the spots fade away.
This inspired him to share his process publicly. His website, Phoenix Tears, became a hub for people seeking educational information about making and using RSO. While his story is personal and not a substitute for medical advice, it sparked global interest in the potential of full-extract cannabis oil.
How RSO Is Made
RSO is created by extracting the full spectrum of cannabinoids, terpenes, and plant compounds from the cannabis flower using a solvent-based process. While Rick Simpson originally used naphtha or isopropyl alcohol, many modern producers use ethanol or CO₂ extraction for a cleaner, safer result.
The process typically involves:
-
Soaking cannabis flower in the solvent to dissolve cannabinoids.
-
Filtering the plant material.
-
Evaporating the solvent gently until a thick, tar-like oil remains.
-
Storing the oil in a syringe or small vial for accurate dosing.
Important note: Making RSO at home can be dangerous due to flammable solvents. Always source your oil from licensed dispensaries or verified suppliers instead of attempting DIY extraction.
RSO vs. Other Cannabis Oils
People often confuse RSO with other cannabis extracts like CBD oil, distillate, or rosin. Here’s how they differ:
|
Type |
Main Compound |
Solvent Used |
Typical Use |
|---|---|---|---|
|
RSO |
THC-dominant |
Alcohol-based (full extract) |
Medical and therapeutic |
|
CBD Oil |
CBD-dominant |
CO₂ or ethanol |
Wellness, relaxation |
|
Rosin |
THC or CBD |
None (heat and pressure) |
Smoking or dabbing |
|
Distillate |
THC or CBD |
Multiple refinement steps |
Vape pens, edibles |
RSO is unrefined and intentionally retains chlorophyll and other plant compounds for what’s often called the “entourage effect.”
How to Use RSO
RSO can be consumed orally, sublingually, or topically—depending on your goals. It’s extremely potent, so always start with a grain-of-rice-sized drop.
Common methods:
-
Oral ingestion: Swallow or place under your tongue for long-lasting effects (up to 6–8 hours).
-
Topical application: Some apply it directly to the skin for localized relief.
-
Capsules or edibles: Mix small doses with food or oil for controlled use.
💡 Pro Tip: Effects usually begin within 45–90 minutes after ingestion. If you’re wondering how long RSO takes to kick in, it’s slower than smoking or vaping—but lasts much longer.
RSO Dosage Basics
Because RSO is so strong, dosing must be approached gradually. Many educational sources recommend a 90-day “RSO regimen” that slowly increases the dose.
Here’s a simplified outline:
-
Weeks 1–2: Start with a drop the size of half a grain of rice daily.
-
Weeks 3–4: Gradually double your intake every few days as tolerated.
-
Week 5 onward: Work up to 1 gram per day if your system allows.
