Rick Simpson Oil (RSO) in North America: The Complete Guide by OilWell Cannabis
Why RSO Matters in North America
Rick Simpson Oil (RSO) has become one of the most sought-after cannabis extracts in North America, particularly among patients seeking natural alternatives for chronic pain, cancer support, sleep disorders, and anxiety. But what exactly is RSO, and how does it fit into North America’s evolving cannabis landscape?
For many in North America, RSO represents more than just a product—it’s a symbol of hope, resilience, and the growing acceptance of cannabis as a therapeutic option. Whether you’re in a state with legal medical cannabis, a province with regulated access, or an area where hemp-derived products are the only legal option, RSO offers a powerful, full-spectrum approach to wellness.
At OilWell Cannabis, we’ve taken the foundational principles of RSO and refined them with modern science, safety, and accessibility in mind. Our goal? To provide North Americans with a legal, lab-tested, and evidence-backed RSO that respects the tradition while addressing its limitations.
The History of RSO: From Rick Simpson to Modern Formulations
Who Was Rick Simpson?
Rick Simpson was a Canadian power engineer who, in 2003, claimed that concentrated cannabis oil helped him treat his basal cell carcinoma (a form of skin cancer). Though his story was never clinically verified, it sparked a global movement. Simpson began distributing his oil for free, helping people with cancer, chronic pain, and other conditions. His documentary, Run From The Cure (2005), spread his message worldwide, including across North America.
Simpson’s work was groundbreaking in two key ways:
- He made cannabis oil accessible—giving it away for free and teaching others how to make it.
- He challenged the medical establishment—arguing that cannabis could be a viable alternative to pharmaceuticals.
However, Simpson’s approach had significant limitations:
- No standardization—Every batch of his oil was different.
- High THC exposure—His protocol involved consuming up to 900mg of THC daily, far beyond what most people can tolerate.
- Solvent risks—He used naphtha or isopropyl alcohol, which can leave harmful residues.
- No terpenes—The extraction process destroyed the aromatic compounds that contribute to cannabis’s therapeutic effects.
How RSO Evolved in North America
In North America, RSO has become a catch-all term for full-spectrum cannabis oil, but not all RSO is created equal. The legal cannabis industry has refined Simpson’s original method, introducing:
- Lab testing—Ensuring potency and safety.
- Multi-cannabinoid formulas—Beyond just THC.
- Terpene preservation—Enhancing therapeutic effects.
- Legal compliance—Meeting federal and state/provincial regulations.
At OilWell, we’ve taken these advancements further by:
✅ Using seven cannabinoids (CBD, CBG, Delta-8 THC, THCa, Delta-9 THC, CBN, CBC) for a broader therapeutic effect.
✅ Including live terpenes (limonene, myrcene, caryophyllene, pinene, linalool, humulene, terpinolene) for enhanced benefits.
✅ Offering THCa in its raw form—letting you control whether it stays non-psychoactive or converts to THC.
✅ Solvent-free production—Using organic MCT oil for safety and purity.
Why OilWell’s RSO Stands Out in North America
1. Legal & Accessible Everywhere in North America
Unlike traditional RSO, which was often sold illegally, OilWell’s RSO is Farm Bill-compliant, meaning it contains less than 0.3% Delta-9 THC. This makes it legal to purchase and ship across the U.S. and many parts of Canada.
- No medical card required—Available to anyone 21+.
- Same-day delivery in Houston—Free delivery to the Texas Medical Center (TMC), the world’s largest medical complex.
- Nationwide & international shipping—Discreet, temperature-stable packaging with full documentation.
2. Patient-Controlled Potency: Use It Raw or Activated
One of the biggest innovations in OilWell’s RSO is THCa preservation. Traditional RSO was always fully decarboxylated (converted to THC), meaning it was always psychoactive. Our formula includes 1,500mg of THCa, which you can:
- Use raw—Non-psychoactive, great for daytime use (anti-inflammatory, neuroprotective).
- Decarboxylate at home—Convert THCa to THC for full psychoactive effects (pain relief, sleep support).
This gives North Americans full control over their experience—something Simpson’s original oil never offered.
3. Open-Source Formulas: Make It Yourself If You Can’t Afford It
Simpson gave his oil away for free. We honor that spirit by publishing our exact formulas so anyone can make their own version. If you can’t afford our $129.99 sublingual oil or $49.99 vape cartridge, you can source the ingredients and follow our recipe.
4. Solvent-Free & Lab-Tested for Safety
Traditional RSO used naphtha or isopropyl alcohol, which can leave harmful residues. Our RSO is:
- Made with organic MCT oil—No solvents, no contaminants.
- Third-party lab tested—Potency, terpenes, pesticides, heavy metals, residual solvents, and microbials.
- COAs available—Full transparency for North American consumers.
5. Two Formats for Different Needs
We offer RSO in two delivery methods:
| Format | Best For | Onset Time | Duration |
|---|---|---|---|
| Sublingual Oil | Sustained relief, precise dosing, daytime use | 15-45 min | 4-6 hours |
| Vape Cartridge | Fast relief, breakthrough pain, nighttime use | 1-2 min | 2-4 hours |
How OilWell’s RSO Compares to Traditional RSO
| Feature | Traditional RSO | OilWell RSO |
|---|---|---|
| Source Material | Single high-THC strain | Multi-cannabinoid blend |
| Extraction Method | Naphtha/isopropyl alcohol | Food-grade ethanol/CO₂ |
| Cannabinoid Profile | THC-dominant, uncontrolled | 7 defined cannabinoids (CBD, CBG, Delta-8, THCa, Delta-9, CBN, CBC) |
| Terpenes | Destroyed by heat | 5% live terpenes (7 defined) |
| Standardization | None (every batch different) | Lab-tested, 553mg/mL |
| Residual Solvents | High risk | None (tested) |
| THCa Preservation | No (fully decarboxylated) | Yes (1,500mg, patient-controlled) |
| Legal Status | Illegal in most places | Farm Bill-compliant, ships nationwide |
| Dosing Precision | Approximate (syringe-based) | Graduated dropper (0.1mL increments) |
Who Can Benefit from RSO in North America?
RSO is used by North Americans for a variety of conditions, including:
1. Cancer Support (Nausea, Pain, Appetite)
- Delta-8 THC (6,000mg) has strong antiemetic (anti-nausea) effects.
- Delta-9 THC (90mg) helps with chemotherapy-induced nausea and appetite stimulation.
- CBD (4,500mg) may help reduce inflammation and anxiety during treatment.
Recommended Use:
- Pre-chemo: 0.5-1.0mL sublingual 1 hour before treatment.
- Breakthrough nausea: 2-3 vape puffs for immediate relief.
- Sleep support: 1.0-2.0mL sublingual before bed (contains 25-50mg CBN).
2. Chronic Pain (Arthritis, Neuropathy, Fibromyalgia)
- THCa (raw) provides anti-inflammatory effects without psychoactivity.
- Beta-caryophyllene (a terpene) acts as a CB2 agonist, reducing pain signals.
- CBD & CBG work together to modulate pain pathways.
Recommended Use:
- Daytime: 0.3-0.5mL raw sublingual (non-psychoactive).
- Nighttime: 0.5-1.0mL decarboxylated sublingual (for sleep + pain relief).
- Breakthrough pain: Vape as needed.
3. Sleep Disorders (Insomnia, PTSD-Related Sleep Issues)
- CBN (750mg) is a well-known sleep aid.
- Delta-8 THC provides relaxation without the intensity of Delta-9.
- Linalool & myrcene (terpenes) enhance sedative effects.
Recommended Use:
- Before bed: 1.0-2.0mL sublingual (delivers 25-50mg CBN).
4. Anxiety & PTSD
- CBD (4,500mg) has strong anxiolytic (anti-anxiety) effects.
- CBG (3,000mg) may help regulate mood and stress responses.
- Limonene (terpene) has mood-enhancing properties.
Recommended Use:
- Daytime: 0.3mL raw sublingual (non-psychoactive).
- Nighttime: 1.0mL sublingual (full cannabinoid profile).
How to Use OilWell’s RSO Safely & Effectively
General Dosing Guidelines
- Start low, go slow. Begin with 0.25-0.5mL and wait 2-3 hours before increasing.
- Individual responses vary. Factors like body weight, metabolism, and tolerance affect dosing.
- Consult a healthcare provider if you have medical conditions or take medications.
Decarboxylation Guide (Activating THCa)
If you want the psychoactive effects of THC, you can decarboxylate the oil at home:
- Preheat oven to 260°F (125°C).
- Place desired amount of oil in an oven-safe glass container.
- Heat for 45-60 minutes.
- Let cool before use.
Conversion math:
- 1,500mg THCa → ~1,315mg Delta-9 THC
-
- 90mg existing Delta-9 THC = ~1,405mg total Delta-9 THC
Legal & Safety Considerations
⚠️ Important Disclaimer:
- Not FDA-approved for any medical condition.
- May cause impairment—do not drive or operate machinery while using psychoactive forms.
- Consult a doctor if pregnant, nursing, or taking medications.
- Keep out of reach of children.
- Check local laws—while Farm Bill-compliant, some states/provinces have additional restrictions.
