Rick Simpson Oil (RSO) in North America: The Complete Guide to Modern Multi-Cannabinoid Formulas by OilWell Cannabis

Understanding Rick Simpson Oil: From Nova Scotia Roots to North American Accessibility

Rick Simpson was not a doctor. He was not a scientist. He was a power engineer from Amherst, Nova Scotia, who suffered a catastrophic workplace injury in 1997 that left him with persistent tinnitus, dizziness, and post-concussion symptoms that conventional medicine failed to resolve. When he asked his physician about cannabis as an alternative, the request was refused. That moment of dismissal sparked a journey that would eventually create the most recognized name in full-spectrum cannabis extracts: Rick Simpson Oil.

Simpson’s pivotal moment came in 2003, when he applied concentrated cannabis oil to three bumps on his arm that had been diagnosed as basal cell carcinoma. According to his personal testimony, the lesions disappeared within four days. No independent medical verification was ever published. No biopsy confirmation exists in peer-reviewed literature. Yet this unverified personal experience became the foundation of a global movement.

After 2003, Simpson committed himself to producing and distributing concentrated cannabis oil from his property in Maccan, Nova Scotia. He gave it away for free to cancer patients and others suffering from chronic pain, diabetes, infections, glaucoma, arthritis, depression, and insomnia. He charged nothing. His 2005 documentary, Run From The Cure, distributed freely online, introduced the concept of RSO to cannabis communities worldwide. But his advocacy brought him into direct conflict with Canadian law. The Royal Canadian Mounted Police raided his property in 2005 and again in 2009. Facing continued legal pressure, Simpson eventually left Canada for Europe, continuing his advocacy from abroad while maintaining that pharmaceutical companies and government agencies were actively suppressing cannabis cures.

Simpson’s traditional RSO protocol was specific and intensive: 60 grams of concentrated oil consumed over approximately 90 days, starting with a dose the size of half a grain of rice and escalating to roughly 1 gram per day. He recommended oral administration as primary, topical for skin conditions, and acknowledged inhalation only for immediate symptom relief. He maintained that patients would develop tolerance to psychoactive effects within three to four weeks, and he urged them not to let the high discourage them from continuing treatment.

However, the traditional RSO that Simpson produced was fundamentally different from what modern science and manufacturing can offer. His source material was single-strain, high-THC indica cannabis with no standardization. His extraction solvent was naphtha—a petroleum-based lighter fluid—or 99% isopropyl alcohol, neither of which is food-grade. The extraction process involved agitating plant material in solvent, filtering through cheesecloth, and evaporating the solvent in a rice cooker at temperatures that destroyed virtually all terpenes and fully decarboxylated all THCa into delta-9 THC. The result was a nearly black, tar-like oil with estimated THC concentrations of 60-90%, no cannabinoid ratio control, no terpene content, no lab testing, and significant residual solvent risk.

At peak dosing, Simpson’s protocol delivered approximately 600 to 900 milligrams of delta-9 THC daily—doses far exceeding anything studied in controlled clinical settings and carrying serious risks including severe intoxication, impairment, anxiety, and cannabis use disorder. The protocol was never validated in randomized controlled trials, and no human clinical trial has ever demonstrated that traditional RSO cures cancer.

Yet Simpson got something profoundly right: he drew attention to cannabinoids as a serious area of biomedical research when the world was ignoring them. He helped create the political and cultural conditions for the legal cannabis industry that now serves millions across North America. The term “RSO” remains the most recognized name for full-spectrum cannabis extract in the consumer vocabulary.

The Evolution from Traditional to Modern RSO

Today, the term RSO is used broadly across North American dispensaries, often referring to any full-spectrum extract in a syringe format, regardless of quality or composition. Many products bearing the RSO label bear little resemblance to what Simpson originally made. Simpson himself has been critical of commercial products that use the RSO name while departing from his original method, and he maintained an anti-commercial philosophy—giving oil away for free and urging people to make their own rather than buy from companies.

We respect that ethos. We also recognize that modern RSO has evolved substantially from its origins, and those changes matter for patients across North America who seek safe, standardized, effective cannabinoid medicine.

Traditional RSO vs. Modern Formulated RSO

Dimension Traditional RSO OilWell Formulated RSO
Source Material Single high-THC indica strain, uncontrolled Multi-cannabinoid blend from multiple sources, standardized
Extraction Method Naphtha or isopropyl alcohol Modern food-grade ethanol or CO₂ methods, solvent-free final product
Cannabinoid Profile THC-dominant (60-90%), uncontrolled Seven defined cannabinoids at specific ratios: CBD, CBG, Delta-8 THC, THCa, Delta-9 THC, CBN, CBC
Terpene Content Destroyed by high-heat process Live terpenes at 5% with defined seven-terpene profile
Standardization None—every batch different Lab-tested with specific mg/mL targets (553mg/mL total cannabinoids)
Residual Solvents Significant risk with naphtha Controlled and tested—organic MCT oil base
Dosing Precision Approximate, syringe-based Measured per mL with graduated dropper (0.1mL increments)
Product Formats Single thick oil only Sublingual oil (30mL) and vape cartridge (1g) with format-specific formulas
THCa Preservation No—fully decarboxylated by heat Yes—THCa included as distinct ingredient at 1,500mg
Delta-9 THC Content 600-900mg/day at peak dosing 90mg total in bottle (3mg/mL)—well under 0.3% Farm Bill threshold
Evidence Approach Anecdotal, personal testimony Research-backed, evidence-weighted with 29 peer-reviewed citations

The OilWell Story: From the Borderplex to Houston’s Medical Center

OilWell Cannabis was founded by Colin Valencia in Houston, Texas, but the company’s roots trace back to McAllen, Texas—right across the river from Reynosa, Tamaulipas, Mexico. The McAllen-Reynosa area, known as the Borderplex, is one of the most economically challenged and dangerous regions along the U.S.-Mexico border. Colin’s childhood was marked by exposure to violence, cartel activity, and the loss of friends to prison or death. By sixteen, he had left home for good, choosing cannabis over darker paths available to him in that environment.

Despite these challenges, Colin did not fall into the darkest options. He focused on cannabis, seeing it as a safer alternative to harder substances, and grew up in the traditional cannabis world long before legalization. Later, he became a formally trained software engineer and did custom development work for Baylor College of Medicine—one of the most prestigious medical institutions in the Texas Medical Center. That combination of deep cannabis plant knowledge plus medical-grade technical precision defines OilWell’s approach.

But the company’s true origin story begins with a dog named Bentley.

Bentley was paralyzed in his back legs, facing euthanasia. Veterinarians said pain medications would destroy his internal organs, leaving only the choice between prolonged suffering and mercy killing. In a desperate search for alternatives, a rescue worker named Jessica asked Colin: “You’ve moved how many tons of weed and you’ve never heard of CBD?”

That question changed everything. Colin created CBD golden paste for Bentley—a formula combining organic turmeric powder, coconut oil, black pepper, and CBD oil. Bentley got up. He walked over to Colin and brought him his ball to play. From paralyzed and facing euthanasia to fetching his ball. Dogs do not respond to placebo. This was cannabinoid medicine doing what pharmaceuticals could not.

Bentley lived another ten years, passing naturally at age twenty. During those ten years, Colin developed specialized cannabis formulas for every age-related condition Bentley faced: neurodegeneration (CBG neuroprotection, THCa PPARγ agonism), dementia (CBC neurogenesis), glaucoma (THC CB1 agonism), and crippling arthritis (multi-pathway anti-inflammatory approaches using CBD, CBG, THCa, and beta-caryophyllene). Single cannabinoids were not enough. Bentley’s evolving conditions required multi-cannabinoid synergy.

Colin also knows pharmaceutical dependence personally. He struggled with PTSD and benzodiazepine addiction, eventually quitting Xanax cold turkey—a feat that is notoriously difficult and dangerous—using the cannabinoid knowledge he had developed keeping Bentley alive. The Peace Gummies formula that became an OilWell product was created during midnight experiments while fighting through benzo withdrawal. To this day, Colin personally uses the vape form of that formula to manage his insomnia and severe PTSD.

This is not theoretical knowledge. This is lived experience.

Media Recognition: Houston’s Go-To Cannabis Authority

Between September 2019 and April 2023, ABC13 Houston (KTRK)—the ABC affiliate serving America’s fourth-largest city—featured Colin Valencia and OilWell Cannabis in seven distinct news segments spanning business, law, medicine, community health, and politics. Five different reporters sought Colin out across those years. No other Houston cannabis operator appears with that frequency or across that breadth of subject matter.

In September 2019, Colin told ABC13: “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 quote became the philosophical foundation of OilWell.

In May 2021, when ABC13 investigated Delta-8 THC, Colin offered radical honesty on mainstream television: “I don’t give a sh* if it’s wrong to say you’ll get high off it. Maybe you want to get high.”* The network aired it uncensored, balancing his stance with medical caution from UTHealth and regulatory advocacy from Texans for Responsible Marijuana Policy.

In August 2021, OilWell gave away 1,000 special edition caviar pre-rolls—approximately $35,000 in product—to encourage COVID-19 vaccination, coordinating with the city of Houston to help as many people as possible. In October 2021, when Texas suddenly classified Delta-8 as a Schedule I controlled substance, Colin proactively removed all Delta-8 products from shelves before enforcement began, then warned other operators who were unknowingly shipping what had become felony-level narcotics overnight.

In October 2022, Colin revealed to ABC13 that he has personally faced charges for marijuana possession—transforming every prior quote about therapy, pain, and justice with the weight of lived experience. He told reporter Nick Natario: “I would love to see people not get hurt for this anymore.”

By April 2023, Colin was explaining industry dynamics on camera with the confidence of a sector leader, framing the present as a “Renaissance” period for legal cannabis innovation.

This media record—spanning four years, five reporters, and seven features—represents independently verified credibility that cannot be purchased, only earned.

The OilWell RSO Philosophy: Four Core Principles

OilWell’s RSO is not traditional Rick Simpson Oil. It is a formulated, multi-cannabinoid product informed by the RSO tradition but departing from it in deliberate, evidence-motivated ways.

1. Accessibility Over Gatekeeping
No medical card is required. Anyone age twenty-one or older can purchase. We ship nationwide across the United States and internationally to customers who verify local legality. Simpson believed medicine should be accessible to everyone; we built a product and distribution model that makes that accessible legally.

2. Patient-Controlled Potency
THCa is sold in its acidic, non-psychoactive form. You decide whether to use it raw for non-psychoactive benefits or to decarboxylate it into delta-9 THC for full psychoactive potency. Simpson believed patients should control their own medicine; we engineered a product that puts that control in your hands through chemistry rather than rhetoric.

3. Open-Source Formulas
We publish our complete formulas publicly—every cannabinoid, every milligram amount, every percentage—so that anyone who cannot afford the product can source ingredients and make their own version. Simpson gave his oil away for free and taught people how to make it; we adapted that ethos for the modern cannabinoid marketplace by selling a professionally manufactured product and publishing the recipe.

4. Evidence-Informed, Not Evidence-Overstating
We commit to honest education about what the science actually says. Where Simpson operated without access to peer-reviewed literature or clinical trial data, we have that access and use it to distinguish between what is well-supported, what is emerging, and what is overstated.

The Science Behind the Formulas

Our formulations are anchored to peer-reviewed evidence using a formal hierarchy: human clinical evidence first, then systematic reviews and meta-analyses, then institutional summaries, then preclinical and mechanistic literature. This matters because the evidence base is not evenly distributed.

CBD (4,500mg in Sublingual Oil)
The strongest human evidence in our formula set. Purified CBD has credible human evidence in seizure disorders, with additional promising but heterogeneous data for anxiety and pain. A 2024 systematic review and meta-analysis covering 316 participants across eight studies reported statistically significant anxiolytic effects, though more trials are needed. For pain, a 2024 review concluded the literature is promising but limited by trial quality and consistency. Safety considerations include potential liver enzyme elevation and drug-drug interactions, especially relevant for concentrated oral products.

CBG (3,000mg)
The biosynthetic precursor to several major cannabinoids, CBG appears pharmacologically distinct from both THC and CBD. Review literature describes interactions spanning cannabinoid receptors, alpha-2 adrenoceptors, and 5-HT1A-related signaling. Published reviews discuss possible relevance to neurologic disorders and inflammatory bowel disease, but these are primarily pharmacology-led hypotheses rather than mature human therapeutic conclusions. CBG is commercially interesting precisely because it is underexplored, but claims should remain conservative.

Delta-8 THC (6,000mg)
Pharmacologically relevant, psychoactive, and much less clinically characterized than delta-9 THC. A 2022 review concluded that delta-8 and delta-9 THC have broadly similar pharmacokinetic and pharmacodynamic behavior, with delta-8 acting as a partial CB1 agonist that appears less potent than delta-9, likely due to weaker CB1 affinity. However, a 2023 scoping review found that much of the delta-8 evidence base is still dominated by animal studies and public-health concerns rather than strong modern human trials, with reports of adverse consequences and regulatory uncertainty.

THCa (1,500mg)
The acidic precursor to THC, THCa represents a significant share of THC-related content in raw plant material. Critically, THCa itself does not produce psychoactive effects associated with THC, but heating or processing converts it to THC. In vitro and rodent literature suggest anti-inflammatory, immunomodulatory, neuroprotective, and antineoplastic possibilities, but these are not equivalent to established human outcomes. Our product preserves THCa as a distinct ingredient, giving you the choice to use it non-psychoactively or convert it through decarboxylation.

Delta-9 THC (90mg)
The most evidence-developed psychoactive cannabinoid, with established relevance to chemotherapy-related nausea, appetite and weight loss in HIV/AIDS, and some pain-related outcomes. However, it carries the clearest adverse-effect burden, including impairment, motor vehicle crash risk, cannabis use disorder, and potential psychiatric effects at high concentrations. Our formula contains only 90mg total delta-9 THC in the entire 30mL bottle—3mg per mL—well under the 0.3% Farm Bill threshold, dramatically lower than traditional RSO’s 600-900mg daily exposure.

CBN (750mg)
Often marketed for sleep, but the clinical support is far thinner than the marketing suggests. A 2021 narrative review screened 99 human-study abstracts and found no clinical trials using validated sleep questionnaires or formal polysomnography that could substantiate strong sleep-promoting claims. While culturally associated with sedation, current evidence supports cautious phrasing rather than firm promises.

CBC (750mg)
Emerging and intriguing, but overwhelmingly preclinical. A 2024 review highlighted antinociceptive, antibacterial, and anti-seizure areas as interesting research targets, but noted that over-the-counter CBC products are already being sold despite little evidence establishing clinical efficacy or safety.

The Terpene Profile (5% in Both Products)
Our seven-terpene profile includes limonene (citrus-bright), myrcene, caryophyllene (pepper/spice), pinene (forest-fresh), linalool (floral/lavender), humulene (earthy/woody), and terpinolene (piney/fruity). Terpene bioactivity is plausible—beta-caryophyllene is a selective CB2 receptor agonist, limonene shows antioxidant and anti-inflammatory signals in preclinical work, and pinene and linalool have neuroprotective hypotheses—but robust proof of clinically meaningful entourage effects in humans remains limited. We include these terpenes because the science is plausible and the sensory experience matters, not because we overstate the evidence.

The Decarboxylation Choice: Legal Cannabis Access Through Chemistry

The 2018 Farm Bill legalized hemp and hemp-derived products containing less than 0.3% delta-9 THC by dry weight at the federal level. Our RSO Sublingual Oil contains only 90mg of delta-9 THC in the entire 30mL bottle—well under the 0.3% threshold. All cannabinoids are hemp-derived.

THCa is the acidic, non-psychoactive precursor to delta-9 THC. It is not itself delta-9 THC, making it Farm Bill compliant at the point of sale. However, you can decarboxylate THCa into delta-9 THC at home by heating the oil at 260°F (125°C) for 45 to 60 minutes in an oven-safe glass container. This converts 1,500mg of THCa into approximately 1,315mg of delta-9 THC. Combined with the existing 90mg, this yields approximately 1,405mg of total delta-9 THC—giving the product psychoactive potency comparable to traditional illegal RSO, entirely at your discretion after purchase.

This means the same product can function as:

  • Non-psychoactive anti-inflammatory (used raw, THCa stays inactive, zero impairment, compatible with work and driving)
  • Full-potency psychoactive medicine (after home decarboxylation)
  • Fast-acting relief (via the vape cartridge, which auto-decarboxylates THCa at 400-450°F with each inhalation)

The conversion chemistry: 1mg THCa = 0.877mg delta-9 THC after decarboxylation, reflecting the loss of a CO₂ molecule during the reaction.

This framework creates legal cannabis access across North America. A cancer patient in Canada, a chronic pain sufferer in Mexico, or a veteran in the United States can access the same clinical-strength multi-cannabinoid RSO formula that a Houston resident receives via same-day delivery—legally, because the product ships as a hemp-derived, sub-0.3% delta-9 THC product that you activate according to your needs and local laws.

The Open-Source Commitment: Bentley’s Golden Paste and the RSO Recipe

We publish our complete RSO formulas publicly. If you cannot afford our products, you can see exactly what the formula contains, source the individual cannabinoid distillates and isolates, and make your own version.

This philosophy started with Bentley. On our About Us page, we published the actual CBD golden paste recipe that saved his life:

CBD Golden Paste for Pets

  • 1/2 cup organic turmeric powder
  • 1 cup water
  • 1/3 cup coconut oil (unrefined, organic)
  • 1 to 2 teaspoons freshly ground black pepper (important for absorption)
  • CBD oil (dosage depends on pet size; consult a veterinarian)

Mix turmeric and water in a saucepan over low heat, stirring until thick paste forms (7-10 minutes). Add coconut oil and pepper. Cool and store in refrigerator for up to two weeks. Mix with food once or twice daily.

This recipe—published for free, years before our RSO formulas—demonstrates that the open-source pattern is consistent. We give away the formula that saved Bentley, and we give away the formula designed for people. The open-source ethos is not a marketing strategy. It is foundational behavior.

Quality Assurance and Safety

Our RSO is not an extraction product in the traditional sense. It is a formulated blend of individual cannabinoid distillates and isolates combined at specific ratios in a controlled production environment. No naphtha. No isopropyl alcohol. No butane. No extraction solvents are present in the finished product.

We use organic MCT oil (medium-chain triglycerides) as the carrier base—a food-grade lipid that facilitates cannabinoid absorption through sublingual tissue and provides a neutral taste profile, a significant improvement over the tar-like consistency and solvent-residual odor of traditional RSO.

Third-party lab testing covers:

  • Potency testing: HPLC/UHPLC analysis confirms every cannabinoid to ±2% accuracy
  • Heavy metals screening: ICP-MS testing for arsenic, cadmium, lead, mercury below FDA limits
  • Pesticide analysis: 400+ compound screening via LC-MS/MS and GC-MS/MS
  • Residual solvents: FDA Class 3 limits (<5,000 ppm) verified by headspace GC
  • Microbial testing: Comprehensive pathogen screening including E. coli, Salmonella, Aspergillus

Certificates of Analysis (COAs) are available on request.

Competitive Context: Why OilWell RSO Differs

vs. Texas TCUP Dispensary RSO
TCUP (Texas Compassionate Use Program) dispensary RSO typically offers THC-only products (approximately 420mg THC per 0.5g syringe) with zero CBG, CBN, or CBC, requiring a medical card with qualifying conditions. Our formula offers seven cannabinoids including 3,000mg CBG and 750mg CBN, with no medical card required and patient-controlled potency via THCa preservation.

vs. Hemp CBD RSO (e.g., Lazarus Naturals)
Typical hemp CBD RSO offers approximately 1,000mg total cannabinoids per 10mL. Our sublingual formula offers 16,590mg total cannabinoids per 30mL—over sixteen times the cannabinoid density—with the addition of Delta-8 THC, THCa convertible to Delta-9 THC, and a full terpene profile.

vs. Traditional Illegal RSO
Traditional RSO uses toxic solvents (naphtha/isopropyl), has no lab testing, no terpene content, and forces 600-900mg daily Delta-9 THC exposure. Our product uses solvent-free production, full panel testing, live terpenes at 5%, and gives you control over your Delta-9 THC exposure—from zero (raw) to approximately 1,405mg total (if fully decarboxylated).

Conclusion: More Than a Brand

OilWell Cannabis is more than a brand—it is a promise to deliver the best, most thoughtful cannabis products available. We are not here to follow trends. We are here to set them.

From the moment Bentley got up, walked across the room, and brought his ball to play, we understood that cannabinoid medicine is real, that multi-cannabinoid synergy matters, and that patients deserve both scientific precision and human compassion.
