Rick Simpson Oil (RSO) in North America: The Complete Evidence-Based Guide by OilWell Cannabis
For decades, North Americans living with cancer, chronic pain, PTSD, and other debilitating conditions have searched for alternatives when conventional medicine falls short. From the oncology wards of Toronto’s Princess Margaret Hospital to the VA clinics across Texas, from the chronic pain support groups in rural Montana to the anxiety communities of coastal California, the story is the same: people are looking for options that work, that they can control, and that they can access without jumping through bureaucratic hoops. This guide is for every North American who has ever typed “RSO near me” into a search bar at 2 AM, hoping for something real.
We are OilWell Cannabis, a Houston-based cannabinoid company born not in a boardroom, but in the crucible of real suffering and real healing. We didn’t start with a business plan—we started with Bentley, a paralyzed dog facing euthanasia, and a question that changed everything: “You’ve moved how many tons of weed and you’ve never heard of CBD?” That question came from a rescue worker named Jessica in 2013. It led us down a path that would eventually create the most transparent, evidence-grounded, and accessible RSO formulation available in North America today.
This isn’t traditional Rick Simpson Oil. It’s something better: a modern, multi-cannabinoid, patient-controlled formula that honors Simpson’s original vision of accessibility while solving the safety, standardization, and legal problems that made his underground product impossible to scale across a continent as vast and legally complex as North America.
Who Was Rick Simpson, and Why Does He Still Matter in North America?
Rick Simpson was born in 1949 in Amherst, Nova Scotia—just across the border from Maine, in a region where Atlantic Canadians and New Englanders share more than geography. He wasn’t a doctor, oncologist, or researcher. He was a power engineer, a blue-collar tradesman who understood machinery, heat, and pressure. His story begins where too many North American stories begin: with a workplace injury and a medical system that failed him.
In 1997, Simpson fell from scaffolding at a hospital in Moncton, New Brunswick. The concussion left him with tinnitus, dizziness, and chronic pain that pharmaceuticals made worse, not better. When he asked his doctor about cannabis, the answer was no—just as it was for millions of North Americans in the 1990s, before medical programs existed in Canada or the United States. This is the universal North American experience that still resonates: being told your pain isn’t real enough for effective treatment, or that your only option is addictive medication that trades one problem for another.
Simpson’s pivot point came in 2003 when he developed basal cell carcinoma on his arm. Instead of surgery, he applied concentrated cannabis oil he made himself. According to his account—documented in his book Phoenix Tears and the 2005 documentary Run From The Cure—the lesions disappeared in four days. No biopsy confirmed it. No oncologist examined the outcome. But in an era when North Americans were just beginning to discover cannabis as medicine, his personal testimony became a catalyst.
Important Context for North American Readers: Simpson’s story is historically significant, not medically verified. For every patient in Vancouver’s Downtown Eastside, every veteran in Phoenix, every cancer survivor in Newfoundland who swears by RSO, the evidence remains anecdotal. That doesn’t diminish the story’s importance—it simply means we must distinguish between personal testimony and clinical proof. North Americans deserve that honesty.
The Traditional RSO Protocol: What North Americans Need to Know
Simpson developed a specific 60-gram, 90-day oral protocol that became legendary across North America:
- Week 1: Half a grain of rice-sized dose (10-15 mg) three times daily
- Weeks 2-5: Double every four days until reaching 1 gram per day
- Weeks 5-12: Maintain 1 gram daily in three divided doses
- Administration: Primarily sublingual/oral; topical for skin cancers
The goal was 600-900 mg of THC per day at peak dosing—amounts that would render most North Americans unable to work, drive, or parent. Simpson claimed tolerance would build in 3-4 weeks, but that timeline doesn’t match the pharmacokinetic reality for most people on this continent.
Critical Safety Context for North America:
- No controlled trials validate this protocol for any condition
- Traditional RSO was crude, unstandardized, and varied batch-to-batch
- The THC exposure (600-900 mg/day) is 30-45 times higher than FDA-approved dronabinol dosing
- Real risks include severe intoxication, anxiety, tachycardia, and cannabis use disorder
- For North Americans with complex medical conditions—especially cancer patients undergoing chemotherapy—this protocol introduces medical complexity without clinical oversight
What Traditional RSO Actually Was (And Why It Wouldn’t Work in Modern North America)
Traditional RSO was made using naphtha or 99% isopropyl alcohol—neither food-grade. The extraction process destroyed terpenes and left residual solvent risks that no modern North American consumer should accept. Every batch was different because it depended on whatever single indica strain was available. There was no lab testing, no Certificate of Analysis, no consistency.
The product was tar-like, black, and carried a solvent odor. It was fully decarboxylated—meaning all THCa converted to THC—so it was always psychoactive. There was no option for daytime use without impairment, no ability to separate anti-inflammatory benefits from intoxication.
This approach couldn’t scale across North America’s legal patchwork. It couldn’t ship from Houston to Halifax, from Miami to Minneapolis. It couldn’t be sold in licensed dispensaries or meet the quality expectations of North American medical patients who now demand third-party testing.
How OilWell’s Formulas Diverge: Solving North America’s RSO Problems
Our RSO is deliberately different in five evidence-motivated ways that directly address North American market needs:
1. Multi-Cannabinoid Approach Instead of THC Monoculture
Traditional RSO was 60-90% delta-9 THC. Our sublingual formula spreads 16,590 mg across seven cannabinoids:
- CBD: 4,500 mg (anxiolytic, anti-inflammatory)
- CBG: 3,000 mg (neuroprotective, gut health)
- Delta-8 THC: 6,000 mg (pain relief with less anxiety than delta-9)
- THCa: 1,500 mg (non-psychoactive anti-inflammatory, customer-controlled)
- Delta-9 THC: 90 mg (legal under 0.3% Farm Bill threshold)
- CBN: 750 mg (sedative potential, sleep architecture)
- CBC: 750 mg (neurogenesis, mood modulation)
This matters for North Americans because single-cannabinoid approaches fail complex conditions. A veteran in Colorado with PTSD and chronic pain needs more than just THC. A cancer patient in Quebec dealing with chemo nausea and anxiety needs a full spectrum. A fibromyalgia sufferer in Washington State needs multi-pathway anti-inflammation. Our formula delivers that.
2. Terpene Preservation and Addition
Traditional RSO had zero terpenes due to heat destruction. We include live terpenes at 5% with a specific seven-terpene profile:
- Limonene: Citrus-bright mood elevation, anxiety mitigation
- Myrcene: Relaxation and sedation potential
- Caryophyllene: Direct CB2 agonist for inflammation without psychoactivity
- Pinene: Memory and respiratory support
- Linalool: Floral calm for anxiety and stress
- Humulene: Earthy anti-inflammatory
- Terpinolene: Complex piney-fruity spark
For North American consumers already educated about terpenes from legal markets in California, Oregon, Washington, and Canada, this transforms RSO from crude extract to sophisticated formulation.
3. THCa as a Separate Ingredient for Patient-Controlled Potency
Traditional RSO forced psychoactivity. Our formula preserves 1,500 mg THCa in its raw form, giving North Americans three distinct usage pathways:
Option 1: Raw (Non-Psychoactive)
Use straight from the bottle. THCa provides anti-inflammatory benefits via COX-2 inhibition and neuroprotection via PPARγ agonism—without impairment. Perfect for North Americans who work, drive, parent, or operate machinery. No high. No failed drug test risk. Just therapeutic cannabinoid action.
Option 2: Fully Activated at Home
Heat the oil at 260°F for 45-60 minutes. This converts 1,500 mg THCa → ~1,315 mg delta-9 THC. Combined with existing 90 mg delta-9 and 6,000 mg delta-8, you get ~7,405 mg total psychoactive cannabinoids—potency comparable to traditional illegal RSO. All derived from legal hemp. You control the activation, not us.
Option 3: Vape for Instant Relief
Our vape cartridge auto-decarbs THCa at 400-450°F. Every puff delivers freshly activated cannabinoids with 1-2 minute onset—fastest relief available in North America for breakthrough pain, panic, or nausea.
This customer-controlled model solves the biggest limitation of North American medical cannabis programs: lack of dosage flexibility. In Texas, where our Compassionate Use Program caps THC at 1% and requires strict qualifying conditions, our product offers legally accessible potency control. In Canada, where regulated products are often expensive and standardized, we offer customization. In Mexico, where legal frameworks are evolving, we provide a clear legal pathway.
4. Reduced Delta-9 THC Dominance
Simpson’s oil delivered 600-900 mg delta-9 THC daily. Our entire 30 mL bottle contains only 90 mg—3 mg per mL. This dramatically reduces impairment risk while still delivering therapeutic cannabinoids through CBD, CBG, delta-8, and THCa. For North Americans concerned about drug testing, mental health stability, or functional daily use, this is game-changing.
5. Product Format Innovation
Traditional RSO was one thick oil. We offer two formats:
- Sublingual Oil: 30 mL bottle, 553 mg/mL, 15-45 min onset, 4-6 hour duration, 13-19% bioavailability
- Vape Cartridge: 1 gram, 900+ mg, 1-2 min onset, 2-4 hour duration, 10-35% bioavailability
This matters across North America’s diverse geography. A Vancouver Island patient with chronic pain needs sustained relief. A Chicago commuter with sudden panic attacks needs fast-acting vape. A Montreal cancer patient needs precise sublingual dosing. We serve all of them.
The THCa Legal Framework: Why This Works Across North America
Our formula contains less than 0.3% delta-9 THC by dry weight, making it Farm Bill compliant at the federal level in the United States. This same framework enables shipping to Canada under Health Canada’s Industrial Hemp Regulations (IHR) for hemp-derived products with <0.3% THC. For Mexico, where cannabis legalization is evolving, our product meets the legal definition of industrial hemp product.
For North American Customers:
- U.S. Customers: Legal in all 50 states under the 2018 Farm Bill. Ships via USPS, FedEx, UPS. No medical card required. Age 21+.
- Canadian Customers: Legal under IHR for hemp products. We provide full COAs and customs documentation. Note: Canadian law treats THCa differently than delta-9 THC, but our product’s low delta-9 content ensures compliance.
- Mexican Customers: Legal under Mexico’s evolving hemp framework. We ship with full documentation. Customer assumes local legality responsibility.
The conversion math is transparent: 1 mg THCa = 0.877 mg delta-9 THC after decarboxylation. Our 1,500 mg THCa converts to ~1,315 mg delta-9. Combined with 90 mg existing delta-9, that’s ~1,405 mg total. Add 6,000 mg delta-8, and you have a product that can scale from non-psychoactive to highly potent based entirely on customer choice.
Legal Notice for North America: Customers are responsible for understanding their jurisdiction’s laws. We ship with Certificates of Analysis, receipts, and full documentation. International customers accept all customs and legal risk. Void where prohibited.
Open-Source Formulas: The Simpson Ethos Meets North American Transparency
Rick Simpson gave his oil away for free. We can’t do that at scale, but we can publish every milligram of our formula so any North American who can’t afford $129.99 can source ingredients and make their own. This is our commitment to accessibility across a continent with vast economic disparity.

- 1 cup water
- 1/3 cup unrefined organic coconut oil
- 1-2 tsp freshly ground black pepper
- CBD oil (dose per pet weight)
- Simmer turmeric and water into thick paste (7-10 min)
- Add coconut oil and pepper, mix thoroughly
- Cool, store refrigerated up to 2 weeks

This is what we mean by open-source. We’re not protecting a secret formula. We’re sharing the knowledge so North Americans can make informed choices, whether they buy from us or not.
Why Our Origin Story Matters for North America
Colin Valencia grew up in McAllen, Texas—minutes from Reynosa, Mexico—in one of North America’s most economically challenged and dangerous border regions. The Borderplex taught him what desperate people will do when systems fail them. He lost friends to violence and prison. He left home at sixteen. He chose cannabis over darker paths, learning the plant intimately in the underground years before North American legalization.
That border experience shaped our mission. We understand that a cancer patient in Nuevo Laredo has the same desperation as one in Laredo, but different legal access. We know that a veteran with PTSD in Tijuana faces the same pharmaceutical failures as one in San Diego. North America’s border dynamics mean legal status shouldn’t determine who gets relief.
When Colin worked as a software engineer for Baylor College of Medicine in the Texas Medical Center—the largest medical complex in the world—he learned medical-grade precision. When his own PTSD and Xanax addiction hit bottom, he used cannabinoid knowledge from Bentley’s decade of formula refinement to quit benzodiazepines cold turkey. The Peace Gummies formula—now one of our top products—was created during midnight withdrawal experiments. Colin personally uses the vape form for insomnia and severe PTSD.
This isn’t corporate marketing. This is lived North American experience: border hardship, medical system frustration, pharmaceutical failure, and cannabinoid discovery. That’s why doctors across North America use our formulas for Crohn’s, IBS, ulcerative colitis, PTSD, benzo addiction, and insomnia. That’s why we design for vegans, diabetics, and specific health needs.
ABC13 Media Recognition: Independent Verification for North America
Between 2019 and 2023, ABC13 Houston featured us in seven news segments. Five different reporters—Tom Abrahams, Steve Campion, Shelley Childers, Nick Natario, KTRK staff—sought us out. No other Houston cannabis operator matches that frequency or breadth. For North American customers skeptical of cannabis marketing, this is third-party validation from a major-market ABC affiliate.
Key Moments:
-
2019: First feature. Colin’s quote: “I’m not trying to sell people snake oil… I’m not trying to sell people hope, but there’s enough research out there that people just need to know and try and have the best possible version to base their opinions off of to give it a fair shot as to whether it’s right or wrong for them.” That principle still guides every word in this guide.
-
2021 Delta-8 Feature: Steve Campion asked why someone would smoke Delta-8. Colin’s unfiltered answer: “Maybe you want to get high.” That honesty—aired uncensored on ABC—establishes our credibility. We don’t hide what these products do.
-
2021 COVID Giveaway: We donated $35,000 in caviar pre-rolls to encourage vaccination. We coordinated with the City of Houston. No political agenda—just community health. That’s the North American spirit of mutual aid.
-
2021 Delta-8 Ban: When Texas reclassified Delta-8 as Schedule I overnight, Colin removed all products before enforcement, warned other operators they were shipping narcotics, and absorbed the revenue loss. Ethical action before profit.
-
2022 Biden Pardon: Colin revealed his personal marijuana conviction history on camera. “I would love to see people not get hurt for this anymore.” This isn’t theoretical—it’s lived.
-
2023 Renaissance: “Right now is actually a pretty—like Renaissance—pretty important time that should be enjoyed now.” We’re building the future of North American cannabis access.

How Our Formulas Connect to Evidence
Every cannabinoid and terpene in our formula is anchored to peer-reviewed literature from the General Knowledge section. We don’t exempt ourselves from evidence standards.
- CBD (4,500 mg): Strongest human evidence for epilepsy, emerging for anxiety/pain, safety concerns for liver enzymes and drug interactions [1][3][4][6]
- CBG (3,000 mg): Promising minor cannabinoid, mostly preclinical, sold commercially ahead of data [7][8]
- Delta-8 THC (6,000 mg): Psychoactive, pharmacologically close to delta-9, less potent but real effects [9][10][11]
- THCa (1,500 mg): Non-psychoactive acidic precursor, converts with heat, relevant anti-inflammatory potential [12]
- Delta-9 THC (90 mg): Established for nausea/appetite, carries psychiatric and intoxication risks [1][13][15]
- CBN (750 mg): Reputation as sleep aid outpaces clinical evidence [16][17]
- CBC (750 mg): Emerging, preclinical, distinct pharmacology [18][19]
- Terpenes: Plausible bioactivity, limited human cannabis-specific trials, entourage effect still developing [20][29]
We hold ourselves to the same scrutiny we apply to the field.
