Rick Simpson Oil (RSO) in Colorado: The Complete Guide by OilWell Cannabis
Colorado has always been ahead of the curve. From the first legal recreational cannabis sales in 2014 to the thriving medical program that’s helped countless patients, our state understands cannabis better than most. But here’s what even seasoned Colorado cannabis consumers often miss: not all “RSO” is created equal, and the original Rick Simpson Oil—the stuff that started this global movement—was never designed for the precision and safety standards we expect today.
We’re OilWell Cannabis, a Houston-based company that spent years perfecting what RSO can be when you combine Rick Simpson’s grassroots vision with modern science, medical-grade precision, and absolute transparency. We ship our complete, lab-tested RSO formulas directly to Colorado—no medical card required, no dispensary visits, no compromise. Whether you’re in Denver’s urban core, Boulder’s wellness community, Colorado Springs’ veteran networks, or the mountain towns where chronic pain is a daily reality, this guide is for you.
What RSO Really Is—and Why Colorado Needs a Better Option
Who Was Rick Simpson? (And Why His Story Still Matters)
Rick Simpson wasn’t a doctor. He wasn’t a scientist. He was a power engineer from Nova Scotia who got hurt on the job in 1997—fell from scaffolding, suffered a head injury, and lived with tinnitus and dizziness that prescription drugs couldn’t fix. When cannabis helped him more than anything his doctor prescribed, he asked for medical support. The doctor refused. That moment—being told “no” by a system that had already failed him—started everything.
In 2003, Simpson claimed three bumps on his arm were basal cell carcinoma. He applied concentrated cannabis oil, covered them with bandages, and said they disappeared in four days. No biopsy. No independent verification. No clinical documentation. But that personal experience became the origin story of RSO. Simpson started giving his oil away for free to cancer patients, chronic pain sufferers, and anyone desperate for relief. He claims to have helped dozens with everything from diabetes to glaucoma to PTSD—always free, always cannabis oil made his way.
Here’s the critical context Colorado consumers deserve: Simpson’s story is historically significant, but it’s personal testimony, not medical evidence. He never conducted a clinical trial. He never published peer-reviewed research. His oil was crude, unstandardized, and made with naphtha or isopropyl alcohol—solvents that can leave toxic residues. Every batch was different because he used whatever high-THC indica strain he could source. There were no lab tests, no Certificates of Analysis, no safety screenings.
And yet, his 2005 documentary Run From The Cure spread worldwide. It reached Colorado’s cannabis community early, influencing how many of our local pioneers thought about concentrated cannabis. The term “RSO” became generic—today, Colorado dispensaries sell “RSO” products that bear little resemblance to what Simpson actually made. Some are improvements. Many are just capitalizing on the name.
The Traditional RSO Protocol (And Why It’s Problematic)
Simpson’s famous 60-gram, 90-day protocol was designed around that crude, variable oil. The goal: consume 60 grams of oil, escalating from half a grain of rice (≈10-15mg) three times daily to 1 gram per day (≈600-900mg of THC) by week five. That’s an astronomical dose—far beyond anything studied in controlled human trials. At peak dosing, patients were consuming 600-900mg of delta-9 THC daily, compared to the FDA-approved drug dronabinol’s typical dose of 2.5-20mg per day.
The risks at those doses are real: severe intoxication, anxiety, panic, tachycardia, hypotension, and cannabis use disorder. For cancer patients—who are medically complex—using unregulated, untested oil as primary treatment carries risks that extend beyond the oil itself. Simpson’s protocol was never validated in a controlled trial. It assumes crude material with unknown potency. It was a product of its time—pre-legalization, pre-testing, pre-science.
Colorado’s cannabis consumers are more sophisticated than that. You expect lab-tested products, precise dosing, and honest evidence. That’s exactly what we built.
Why OilWell’s RSO Is Different: The Colorado Advantage
Our Origin Story: Built from Love, Not Profit
Our company didn’t start in a boardroom. It started with a dog named Bentley.
Bentley was paralyzed, facing euthanasia. Vets said pain meds would destroy his organs. The choice was prolonged suffering or mercy killing. Our founder, Colin Valencia, had already seen too much suffering growing up in McAllen, Texas—one of the most economically challenged and dangerous border regions in America. By sixteen, he’d faced every form of violence. He’d lost friends to prison and death. Giving up on Bentley wasn’t an option.
A rescue worker named Jessica asked Colin: “You’ve moved how many tons of weed and you’ve never heard of CBD?” That question exposed a blind spot. Colin knew cannabis recreationally. He didn’t know it medicinally—until he created a CBD golden paste for Bentley. The result? Bentley got up. Walked over. Brought his ball to play. From paralyzed to playing fetch. Dogs don’t respond to placebo. That was cannabinoid medicine succeeding where pharmaceuticals failed.
Bentley lived ten more years. During that decade, Colin developed formulas for every age-related condition Bentley faced: neurodegeneration (CBG, THCa), dementia (CBC), glaucoma (THC), crippling arthritis (multi-pathway anti-inflammation). Single cannabinoids weren’t enough. Bentley’s life required multi-cannabinoid synergy—precise, measured, effective.
That same precision is now available to Colorado patients.
Colin’s Personal Journey: From PTSD and Benzo Addiction to Freedom
Colin knows pharmaceutical dependence personally. He struggled with PTSD and Xanax addiction. When he quit cold turkey—a notoriously dangerous feat—he used the cannabinoid knowledge he’d built saving Bentley. The Peace Gummies formula that became one of our bestselling products was created during midnight experiments while fighting through benzo withdrawal. Colin personally uses our vape form for insomnia and severe PTSD.
This isn’t theoretical. It’s lived experience. When we say our products help with PTSD, pain, or sleep, we’re speaking from both science and survival.
Our Philosophy: Four Core Principles for Colorado
-
Accessibility Over Gatekeeping
Colorado has legal dispensaries, but they’re not for everyone. Maybe you don’t want to drive to Denver or Fort Collins. Maybe you live in a mountain town hours from the nearest shop. Maybe you don’t want to register in a state database. We get it. No medical card required. Age 21+ only. We ship directly to your Colorado doorstep—whether you’re in Boulder, Grand Junction, Pueblo, or anywhere USPS delivers. Simpson believed medicine should be accessible to everyone. We built a product and distribution model that makes that real, legally. -
Patient-Controlled Potency
Colorado’s active lifestyle demands flexibility. You might ski Vail in the morning and need to drive home. You might work a shift in Denver’s tech corridor and need to stay sharp. Traditional RSO was always psychoactive—you had no choice. Our sublingual oil contains 1,500mg of THCa in its raw, non-psychoactive form. Use it raw for daytime anti-inflammatory relief with zero impairment. Decarboxylate it at home (260°F for 45-60 minutes) to convert that THCa into approximately 1,315mg of delta-9 THC. Combined with our 6,000mg delta-8 THC, you get full psychoactive potency comparable to traditional illegal RSO—entirely at your discretion. You control the medicine, not the product. -
Open-Source Formulas
Simpson gave his oil away free and taught people to make it. We honor that ethos. We publish our complete formulas publicly—every cannabinoid, every milligram, every percentage—so if you can’t afford our $129.99 sublingual oil, you can source ingredients and make your own. We’re the only company that gives you both a professional product and the recipe. That transparency builds trust Colorado consumers deserve. -
Evidence-Informed, Not Evidence-Overstating
Colorado has world-class research institutions. You can spot overhyped claims a mile away. We hold ourselves to the same standards we apply to everyone else. Our products are anchored to peer-reviewed literature. We distinguish what’s well-supported from what’s emerging. We never promise cures. We provide the best information so you can decide what’s right for you.
The Science Behind Every Drop: Cannabinoids and Terpenes
Seven Cannabinoids, One Purpose
Our RSO Sublingual Oil contains 16,590mg total cannabinoids across seven compounds:
CBD (4,500mg): The most evidence-developed non-intoxicating cannabinoid. Strong human data for certain epilepsies, promising signals for anxiety and pain, but we keep claims conservative. We include it for its foundational role in modulating other cannabinoids.
CBG (3,000mg): The “mother cannabinoid” precursor. Preclinical research shows potential for neuroprotection and inflammation, but human trials are still emerging. We include it because Bentley’s neurodegeneration taught us its value.
Delta-8 THC (6,000mg): A psychoactive THC analogue with real pharmacologic activity, though less potent than delta-9. Provides therapeutic effects while allowing our delta-9 THC to stay under 0.3% for Farm Bill compliance. Not “mild”—just different.
THCa (1,500mg): The game-changer. Non-psychoactive in raw form, convertible to THC when heated. Gives Colorado patients the power to choose their experience. This is innovation Simpson never had.
Delta-9 THC (90mg): Just 3mg per mL—well under the legal limit. We include it because it’s the most clinically studied psychoactive cannabinoid, with established benefits for nausea, pain, and appetite. Combined with delta-8 and convertible THCa, it creates a full-spectrum profile.
CBN (750mg): At 25mg per mL, you’re getting the dosage range investigated in sleep research. We include it for sleep architecture support, but we’re honest: the evidence is still developing.
CBC (750mg): One of the most intriguing minor cannabinoids. Preclinical work suggests anti-inflammatory and neurogenic potential. It’s the frontier of cannabinoid science, and we want Colorado’s research-savvy consumers to have access.
Live Terpenes at 5%: The Entourage Effect, Honest Version
Traditional RSO had no terpenes—heat and solvents destroyed them. We preserve and add live terpenes at 5%:
Limonene (citrus-bright): The mood-lifter. Preclinical antioxidant and anti-inflammatory signals, but we love it for the sensory experience that complements Colorado’s sunny disposition.
Myrcene: The relaxer. Often associated with “couch-lock,” but human evidence for sedation is limited. We include it for its aromatic contribution and plausible synergy.
Caryophyllene (β-caryophyllene): The only terpene proven to interact directly with cannabinoid receptors (CB2). This is real pharmacology, not just aroma. Its peppery spice notes ground the formula.
Pinene (forest-fresh): The clarity terpene. Preclinical neuroprotective signals, plus it evokes Colorado’s pine forests—perfect for patients who moved here for the mountain air.
Linalool (lavender): The calm. Known for stress-reduction potential, but the clinical proof is still catching up to the reputation.
Humulene (earthy, woody): The anti-inflammatory hopeful. Rodent studies show promise, but we include it for the full-spectrum complexity.
Terpinolene (piney, fruity, sparkling): The least-studied in our blend, but it adds a bright top note that makes the oil pleasant to use.
Important honesty: The entourage effect is plausible but not clinically proven in humans for these specific terpenes. We include them because they make the product better—aromatically, sensorially, and potentially pharmacologically—not because we can claim they cure anything.

Competitive Context: Why OilWell Wins in Colorado
Colorado’s market is mature. You can walk into any Denver dispensary and buy “RSO.” But here’s what you’re usually getting:
Most Colorado Dispensary RSO:
- Single-strain, THC-dominant (often 70-90% THC)
- No minor cannabinoids (CBG, CBN, CBC)
- Terpenes destroyed in extraction
- Unknown residual solvents
- Requires medical card or recreational ID (state database)
- Limited to in-person purchase
- No formula transparency
OilWell’s Modern Formulated RSO:
- Seven defined cannabinoids at specific ratios (16,590mg total)
- Live terpenes at 5% with seven defined compounds
- Solvent-free, MCT oil base
- Third-party tested (potency, pesticides, heavy metals, microbes)
- No medical card needed—21+ only
- Ships directly to your Colorado address
- Open-source formula published (make your own if you can’t afford it)
The Math: Our $129.99 bottle delivers 16,590mg of cannabinoids. That’s 16.5 times the total actives of typical hemp RSO products that sell for $40-50. You’re not just paying for premium—you’re paying for clinical-strength sophistication.
Condition-Specific Guidance for Colorado
Chemotherapy-Related Nausea and Appetite
Relevant for Colorado’s cancer patients at UCHealth, Penrose-St. Francis, or Swedish Medical Center
- Pre-chemo: 0.5-1.0mL sublingual 1 hour before treatment
- Acute nausea: 2-3 vape puffs for 1-2 minute relief
- Post-chemo: 0.5mL sublingual every 6 hours as needed
- Sleep during treatment: 1.0-2.0mL sublingual before bed (25-50mg CBN)
Evidence base: Delta-8 THC antiemetic research, delta-9 THC’s established nausea control, CBD’s anxiety buffering.
Chronic Pain (Arthritis, Fibromyalgia, Neuropathy)
For Colorado’s active seniors, veterans, and outdoor enthusiasts
- Daytime: 0.3-0.5mL raw sublingual—anti-inflammatory without impairment so you can hike, bike, or work
- Nighttime: 0.5-1.0mL decarboxylated sublingual—full pain relief plus CBN sleep support
- Breakthrough: Vape as needed for rapid onset
Evidence base: CBD and delta-9 THC pain literature, caryophyllene’s CB2 activation, THCa’s COX-2 inhibition.
Sleep Disorders
For Colorado’s high-altitude insomnia, shift workers, and anxiety-driven sleeplessness
- Before bed: 1.0-2.0mL sublingual delivers 25-50mg CBN—the dosage range from 2024 sleep research
- This provides 4-6 hours of sleep support without next-day groaning
Evidence base: CBN sleep studies [16][17], cannabis-sleep review literature.
Anxiety and PTSD
Especially relevant for Colorado’s veteran community and first responders
- Daytime: 0.3mL raw sublingual—CBD and CBG address anxiety pathways with zero high
- Nighttime: 1.0mL sublingual—full profile including CBN for sleep architecture
Evidence base: CBD anxiety research [3], CBG pharmacology, limonene’s mood-lifting potential.
Titration Principle: Start low, go slow. Colorado’s altitude and individual metabolism affect response. Begin with 0.25-0.5mL, assess effects over 2-3 hours, then adjust.
Legal in Colorado? Absolutely.
Colorado has legal recreational cannabis—we know. But OilWell’s products operate under a different, complementary legal framework:
The 2018 Farm Bill legalized hemp products containing <0.3% delta-9 THC at the federal level. Our sublingual oil contains only 90mg delta-9 THC in the entire 30mL bottle—3mg/mL—well under the limit. All cannabinoids are hemp-derived.
What this means for you in Colorado:
- No medical card needed. Anyone 21+ can order.
- Ships directly to your door. No dispensary visit, no state database.
- Legal possession. The product is Farm Bill compliant at point of sale.
- Customer-controlled activation. THCa is non-psychoactive until you heat it. You decide when and if it becomes THC.
Important legal notice: If you decarboxylate THCa into THC, you are creating a psychoactive substance. Colorado law allows home cannabis processing, but you accept responsibility for compliance with local regulations. We provide full documentation, COAs, and receipts for every order.

Media Recognition: Why ABC13 Trusts Us (And Why That Matters for Colorado)
Between 2019 and 2023, ABC13 Houston featured OilWell in seven news segments. Five different reporters sought us out for expertise on business, law, medicine, and community health. That kind of mainstream media validation from a major-market ABC affiliate is a credibility signal that transcends geography.
What the Media Record Shows:
- September 2019: Colin’s foundational quote—”I’m not trying to sell people snake oil”—established our evidence-first philosophy
- May 2021: Steve Campion’s Delta-8 investigation featured Colin’s iconic “Maybe you want to get high” honesty—radical transparency on mainstream TV
- August 2021: We gave away $35,000 in product to encourage COVID vaccination, coordinating with the City of Houston—real community action
- October 2021: When Texas banned Delta-8 overnight, Colin proactively removed all products and warned other operators—ethical leadership in crisis
- October 2022: Feature revealed Colin’s personal marijuana conviction history—proving this isn’t just business, it’s personal justice
For Colorado: We don’t have Denver news clips. But we have something better: four years of documented integrity from America’s fourth-largest city. That’s the kind of track record you can trust, whether you’re ordering to Boulder or Brighton.

RSO Vape Cartridge Formula ($49.99)
| Cannabinoid | Percentage |
|---|---|
| CBD | 30% |
| CBG | 20% |
| Delta-8 THC | 15% |
| THCa | 10% |
| CBN | 10% |
| CBC | 10% |
Live Terpenes: 5%+
Battery: 510-thread universal (works with any Colorado vape battery)
Why vape? 1-2 minute onset for breakthrough moments. Skiing Mary Jane and your knee locks up? Two puffs. In a meeting in Colorado Springs and anxiety spikes? One puff. The vape auto-decarbs THCa at 400-450°F, giving you instant THC conversion when you need it.
Safety: What Colorado Consumers Must Know
Age: 21+ only
Impairment: May cause drowsiness. Do not operate vehicles or machinery while impaired.
Drug Tests: Raw THCa won’t trigger most tests, but decarbed THC and delta-8 will. Be honest with employers.
Pregnancy: Not recommended. Consult your provider.
Interactions: CBD can interact with medications. Talk to your Colorado doctor, especially if you’re on blood thinners or seizure meds.
Storage: Colorado’s dry climate is perfect for stability. Keep in a cool, dark place. THCa will slowly convert to THC over time at room temperature—refrigerate to preserve raw form.
The Bottom Line for Colorado
You live in a cannabis-savvy state. You know the difference between hype and science. You’ve seen dispensaries come and go. You’ve heard every claim.
OilWell is different because we’re honest. We know Bentley’s story is powerful, but we don’t claim it cures cancer. We know the evidence for CBN sleep benefits is emerging, but we include it at the research-validated dose. We know delta-8 THC is psychoactive, and we tell you straight up. We know you can make this yourself, and we give you the recipe.
We’re a Houston company reaching out to Colorado because your state deserves this option. You have legal dispensaries, but you don’t have this level of multi-cannabinoid precision, terpene preservation, and patient-controlled potency. You don’t have a company that spent ten years formulating for a dying dog and then published the formula for free.
Colorado’s cannabis community helped change the world. We’re here to give you the next evolution.
