Rick Simpson Oil (RSO) in Mendocino County: The Complete Guide by OilWell Cannabis

Mendocino County has always moved to its own rhythm. Tucked between the soaring redwoods and the rugged Pacific coastline, our corner of Northern California has spent decades cultivating a relationship with cannabis that’s as complex and layered as the fog that rolls through our valleys. We know this plant. We’ve lived with it through prohibition and persecution, watched it save lives in our communities, and witnessed the Emerald Triangle’s legacy shape everything from our economy to our cultural identity.

So when Rick Simpson’s story started circulating through Fort Bragg farmers’ markets, Ukiah healing circles, and Willits back-to-the-land gatherings, it landed differently here. We recognized the desperation in his voice—the same desperation we’ve seen in our neighbors when the medical system failed them. But we also know something Simpson didn’t: that real medicine demands precision, safety, and intellectual honesty.

That’s why OilWell Cannabis—born in Houston’s medical innovation hub but built for communities exactly like ours—is reaching out to Mendocino County with something unprecedented. This isn’t just another RSO product. It’s the evolution of the RSO concept, grounded in the same rebel spirit that built the Emerald Triangle, but elevated by medical-grade science, legal compliance, and a commitment to transparency that would make our region’s craft cannabis pioneers proud.

If you’re reading this in your cabin outside Philo, in a clinic in Redwood Valley, or on your phone during a break from trimming in Anderson Valley, this guide is for you. We respect what you know about cannabis. We honor the generations of Mendocino growers who perfected this plant in secret. And we’re here to offer something that builds on that legacy rather than exploits it.

Who Was Rick Simpson, and Why Does His Story Still Matter in Mendocino?

Rick Simpson wasn’t a doctor. He wasn’t a scientist. He was a power engineer from Nova Scotia—a blue-collar tradesman whose life shattered when he fell from scaffolding in 1997. The medical establishment gave him pills that didn’t work and dismissed his questions about cannabis. Sound familiar? It should. We’ve all heard similar stories at the Mendocino Farmers Market, around campfires at Russian River, or in whispered conversations at the Ukiah Co-Op.

When Simpson discovered that 1974 NIH study showing THC could shrink tumors in mice, it lit a fire in him—just like discovering cannabis medicine has lit fires in countless Mendocino households. When three bumps on his arm were diagnosed as basal cell carcinoma in 2003, he applied crude cannabis oil, covered them with bandages, and claimed they disappeared in four days. No biopsy. No medical verification. No follow-up. But that personal testimony became the origin story for what we now call RSO.

Important context: We present Simpson’s story exactly as he told it—personal testimony, not medical evidence. In Mendocino County, where we’ve seen cannabis perform miracles that science can’t yet explain, we understand why anecdotal stories carry weight. We also know the difference between hope and proof.

The Crusade That Reached Mendocino’s Shores

After 2003, Simpson began giving away his oil for free. He helped people with cancer, chronic pain, diabetes, infections, glaucoma, arthritis, depression, insomnia—conditions we see every day in our Redwood Valley clinics, Fort Bragg senior centers, and Willits veterans’ halls. In 2005, the documentary Run From The Cure spread his story globally, and it didn’t take long for those ideas to cross the Canadian border, travel down the West Coast, and take root in the Emerald Triangle’s fertile soil.

The Royal Canadian Mounted Police raided Simpson in 2005 and 2009. He was charged, convicted, and eventually fled to Europe. In Mendocino County, we know that story too well—our own neighbors have faced similar persecution, our own communities have been targeted by federal raids, and our own legacy growers have had to choose between their medicine and their freedom.

What Traditional RSO Actually Was

To understand what makes our formula different, you need to understand what Simpson actually made:

Source material: Single high-THC indica strains with no standardization. If you know Mendocino growers, you know what that means: every batch was different depending on genetics, soil, weather, and grower technique.

Extraction method: Simpson used naphtha (petroleum-based lighter fluid) or 99% isopropyl alcohol. Neither is food-grade. Both carry serious residual solvent risks. In our fog-damp Mendocino climate, those solvents are even more dangerous—flammable vapors linger, and incomplete purging leaves toxic residues that are hard to detect without lab equipment.

Cannabinoid profile: 60-90% delta-9 THC, with minor cannabinoids at whatever ratio the plant happened to produce. No control. No measurement. No consistency.

Terpene content: Essentially zero. The solvent and heat destroyed the volatile terpenes that give cannabis its character and potential entourage benefits. In Mendocino, where terpene preservation is practically a religion among craft growers, this is a fundamental flaw.

Standardization: None. Every batch was unique. No lab testing. No Certificate of Analysis. For a community that values artisanal consistency, this is unacceptable.

Simpson’s 60-Gram Protocol: The Numbers Don’t Lie

Simpson’s famous 90-day regimen requires consuming 60 grams of oil, titrating up to 1 gram per day divided into three doses. At peak dosing, that’s approximately 600-900mg of delta-9 THC daily—doses far exceeding anything studied in controlled trials. The FDA-approved synthetic THC drug dronabinol is typically dosed at 2.5 to 20mg per day. Simpson’s protocol delivers 30 to 300 times that amount.

Critical context: This protocol was never clinically validated. No controlled trials. No dose-finding studies. No pharmacokinetic modeling. For Mendocino County residents considering this approach—perhaps for a loved one at the Mendocino Coast District Hospital or someone in palliative care at Ukiah Valley Medical Center—this matters enormously. High-dose THC carries real risks: severe intoxication, anxiety, panic, tachycardia, hypotension, cannabis use disorder, and dangerous interactions with medications [1][13][15].

What the Science Actually Says About Cannabis and Cancer

We need to be brutally honest here, because that’s what Mendocino County deserves:

What preclinical studies show: In lab dishes and animal models, THC and CBD can induce apoptosis (programmed cell death), inhibit tumor proliferation, and reduce angiogenesis . These findings are scientifically interesting but have NOT translated into proven human cancer cures. The gap between in vitro results and human clinical outcomes is vast—this is true across all of oncology research, not just cannabis.

What human trials show: No published randomized controlled trial has demonstrated that RSO or any cannabis oil cures cancer. Several small exploratory trials in glioblastoma patients have been conducted, but they were not designed to prove cure claims .

What institutions say: The National Cancer Institute acknowledges the preclinical research but does not endorse cannabis as a cancer treatment . The FDA has approved zero cannabis plant products for cancer treatment. Health Canada has never approved RSO for cancer.

Historical truth: Simpson was right that cannabis deserved serious biomedical research. He was wrong that his oil cured cancer. In Mendocino County, where we’ve lost friends and family to this disease, we understand the desperation for hope. But hope cannot replace proven treatment. Using unregulated oil instead of surgery, radiation, chemotherapy, or immunotherapy can cause irreversible harm.

The Legacy: From Black Tar to Modern Medicine

The term “RSO” has become generic. Walk into any dispensary from Eureka to Santa Rosa, and you’ll see products labeled RSO that bear no resemblance to Simpson’s original. Some are distillates. Some are CO₂ extracts. Some are blends. The name has lost its meaning.

Rick Simpson himself has been critical of commercialization. He gave his oil away for free and taught people to make it. OilWell honors that ethos differently: we sell a professionally manufactured, lab-tested, standardized product for those who can afford it, and we publish the complete recipe for those who can’t. For the DIY growers in Anderson Valley, the retired nurses in Willits, the veterans in Fort Bragg living on fixed incomes—this matters.

The OilWell Story: Why a Houston Company Understands Mendocino

OilWell Cannabis was founded by Colin Valencia in Houston, Texas. But Colin’s story begins where many Mendocino stories do: in a place of hardship and resilience.

He grew up in McAllen, Texas, right across the river from Reynosa, Mexico—a border region as economically challenged and violence-scarred as any place in America. By sixteen, he’d seen friends killed or imprisoned. He’d navigated cartel territory and learned to hustle just to survive. He chose cannabis over darker paths, seeing it as the safer, more beneficial alternative—a decision that echoes the choices many Emerald Triangle pioneers made decades ago.

Colin became a software engineer and did custom development for Baylor College of Medicine, one of America’s most prestigious medical institutions. That combination—deep cannabis plant knowledge plus medical-grade technical precision—defines everything OilWell does.

Bentley: The Dog Who Started It All

The company’s origin story isn’t about business plans or venture capital. It’s about a dog named Bentley.

Bentley was family. When veterinarians said his paralysis meant only euthanasia could end his suffering, Colin refused. A rescue worker named Jessica asked the question that changed everything: “You’ve moved how many tons of weed and you’ve never heard of CBD?”

Colin created a CBD golden paste. Bentley got up. He walked. He brought Colin his ball. From paralyzed to playing. This wasn’t placebo—dogs don’t respond to placebo. This was real medicine performing miracles that pharmaceuticals couldn’t.

Bentley lived another ten years, dying naturally at age twenty. During that decade, Colin developed formulas for every condition Bentley faced:

• Neurodegeneration → CBG for neuroprotection, THCa for PPARγ brain cell protection
• Dementia → CBC for neurogenesis
• Glaucoma → THC for CB1-mediated intraocular pressure reduction
• Arthritis → Multi-pathway anti-inflammation using CBD, CBG, THCa, and beta-caryophyllene

Those ten years of formulation, precision, and love became the foundation of the RSO formula we offer Mendocino County today.

Colin’s Personal Battle: PTSD and Benzo Withdrawal

Colin knows pharmaceutical dependence firsthand. He struggled with PTSD and benzodiazepine addiction. When he quit Xanax cold turkey—one of the most dangerous withdrawals imaginable—he used the same cannabinoid knowledge that saved Bentley.

The Peace Gummies formula that helps so many Mendocino veterans with PTSD and insomnia was created during midnight experiments while Colin fought through benzo withdrawal. He personally uses the vape form for his severe PTSD. This isn’t theoretical knowledge from a lab in Houston—it’s survival knowledge from someone who lived what many of our neighbors in Mendocino live every day.

The OilWell RSO Philosophy: Four Principles for Mendocino

Our approach to RSO is guided by four core principles that directly address the limitations of traditional RSO while honoring its rebel spirit:

1. Accessibility Over Gatekeeping

No medical card required. In Mendocino County, where many residents live rurally and can’t easily access doctors for cannabis recommendations, this matters. If you’re twenty-one or older in Ukiah, Willits, Fort Bragg, or anywhere along the Mendocino Coast, you can order our products directly. We ship to your doorstep.

Same-day delivery in Houston; nationwide shipping to Mendocino. We don’t have a physical location in Mendocino County (yet), but we understand your geography. Whether you’re on the coast where fog makes everything damp, in the inland valleys where summer heat is intense, or deep in the redwoods where UPS drivers might need directions—we’ve got you covered. Free delivery to the Texas Medical Center demonstrates our commitment to patients; we’ll extend that same care to Mendocino County addresses.

2. Patient-Controlled Potency

Traditional RSO was always psychoactive. The heat of production converted all THCa to delta-9 THC. You had no choice.

Our sublingual oil contains 1,500mg of THCa in its raw, non-psychoactive form. You decide:

• Raw (no heat): All 1,500mg stays as THCa. Zero psychoactivity. Perfect for daytime use in Mendocino County, whether you’re driving Highway 1, working in the vineyards, or hiking the Lost Coast Trail. You get anti-inflammatory benefits via COX-2 inhibition and neuroprotective effects via PPARγ agonism without any high.

• Fully activated (home decarb): Bake at 260°F for 45-60 minutes. This converts THCa to ~1,315mg delta-9 THC. Combined with our existing 90mg delta-9 and 6,000mg delta-8, you achieve psychoactive potency comparable to traditional illegal RSO—100% legally, because you performed the conversion after purchase.

• Partial activation: Decarb only what you need, preserving the rest raw. This flexibility is revolutionary for Mendocino County’s diverse population—whether you’re a retiree in Fort Bragg managing chronic pain or a young farmer in Anderson Valley dealing with acute stress.

The conversion math: 1mg THCa = 0.877mg delta-9 THC after decarboxylation. We show our work because that’s what transparency looks like.

3. Open-Source Formulas

Rick Simpson gave his oil away for free and taught people to make it. We honor that ethos in the modern era.

Our complete formulas are published publicly—every cannabinoid, every milligram, every percentage. If you’re a DIY cultivator in Mendocino’s Emerald Triangle, someone who knows how to source distillates and prefers to blend your own, or simply can’t afford $129.99 for our sublingual oil—you can make it yourself.

The Bentley Golden Paste Recipe (Published for Free)

We didn’t start with RSO. We started with this:

Ingredients:

• 1/2 cup organic turmeric powder
• 1 cup water
• 1/3 cup coconut oil (unrefined, organic)
• 1-2 teaspoons freshly ground black pepper
• CBD oil (dosage depends on size/needs; consult veterinarian)

Instructions:

1. Mix turmeric and water in a saucepan, stir over low heat until thick paste forms (7-10 minutes)
2. Add coconut oil and pepper, mix thoroughly
3. Cool and store in refrigerator (up to 2 weeks)
4. Add CBD oil before serving

Serving: Mix small amount with pet’s food 1-2x daily. This is the exact recipe that saved Bentley. We published it before we ever sold a product because that’s who we are.

4. Evidence-Informed, Not Evidence-Overstating

Colin’s 2019 ABC13 quote captures our philosophy: “I’m not trying to sell people snake oil… 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.”

This entire document is our evidence foundation. We apply the same rigorous standards to our own products that we apply to Rick Simpson’s claims. No double standard. No special pleading.

The Science: What Mendocino County Needs to Know

We could fill a redwood grove with the cannabis misinformation circulating in Mendocino County. Let’s cut through it.

Our Evidence Hierarchy

We prioritize sources in this order:

1. Human clinical trials (what works in real patients)
2. Systematic reviews and meta-analyses (what patterns emerge across multiple studies)
3. NIH and institutional summaries (what major health authorities conclude)
4. Preclinical/mechanistic literature (how things might work, but haven’t been proven in humans)

What the NIH Says

The National Center for Complementary and Integrative Health (NCCIH) identifies the strongest cannabinoid evidence for:

• Certain rare epilepsies
• Chemotherapy-related nausea/vomiting
• HIV/AIDS-related appetite/weight loss

Only modest evidence exists for chronic pain and multiple sclerosis symptoms. No strong evidence supports most other marketed uses.

The FDA has approved ZERO cannabis plant products for medical use. Only purified CBD (Epidiolex) and synthetic THC analogues (dronabinol, nabilone) have specific approvals.

Critical Safety Concerns for Mendocino Residents

Before you consider any RSO product, understand these risks:

Impairment and Driving: Mendocino County’s winding coastal roads and isolated highways make this especially dangerous. Delta-9 THC impairs motor coordination and reaction time. Our raw THCa option exists specifically so you can medicate without risking a DUI on Highway 1.

Cannabis Use Disorder: High-concentration products can lead to dependency. The 2025 systematic review found consistent links between potent THC products and negative mental health outcomes, including psychosis, anxiety, and depression [15].

Drug Interactions: CBD inhibits liver enzymes (CYP3A4, CYP2C19) that metabolize many medications. If you’re a senior in Fort Bragg on multiple prescriptions, or a cancer patient in Ukiah undergoing chemotherapy, this matters. Consult your physician.

Pregnancy: NCCIH explicitly warns against cannabis use during pregnancy due to risks to fetal brain development.

Product Quality: The unregulated market (including some products in Mendocino County) often contains inaccurate labeling, contaminants, or dangerous synthesis byproducts. Always demand third-party lab testing.

The Truth About CBD

CBD has the strongest human evidence in our formula, but even here, the evidence is concentrated in specific indications, not broad wellness claims.

Seizure disorders: Strong evidence in rare pediatric epilepsies [2].

Anxiety: A 2024 systematic review of 316 participants found significant anxiolytic effects, but authors stressed the limited clinical sample [3].

Pain: A 2024 review concluded the literature is “promising but heterogeneous,” with trial quality limiting confidence [4].

Sleep: A 2023 review found methodological weaknesses, with few objective sleep assessments [5].

Liver safety: A 2023 meta-analysis found real signals of liver enzyme elevation and possible drug-induced liver injury, especially concerning for concentrated oral products [6].

The Truth About CBG, CBN, CBC, and Delta-8

CBG: Review-level evidence only. Human trials are sparse. Interesting pharmacology but not clinically validated [7][8].

CBN: Marketing has far outpaced data. The 2021 review screened 99 human-study abstracts and found NO clinical trials using validated sleep measures that could substantiate strong sleep-promoting claims [16]. The 2024 sleep review concluded cannabinoid sleep research doesn’t match real-world use scale [17].

CBC: Emerging preclinical evidence. Over-the-counter products are already sold despite little evidence establishing clinical efficacy or safety [18][19].

Delta-8 THC: Pharmacologically similar to delta-9 THC but less potent. A 2022 review found comparable pharmacokinetics [9]. A 2023 scoping review noted adverse consequences and regulatory concerns [10]. It is psychoactive and will cause impairment.

The Entourage Effect: Hope vs. Hype

The 2024 comprehensive review concluded that terpene bioactivity is plausible, but robust proof of clinically meaningful entourage effects in humans remains limited [20]. Most terpene claims come from preclinical models, essential oil studies, or non-cannabis plants.

For Mendocino County’s terpene-conscious consumers: We include live terpenes at 5% because the science is plausible and the sensory experience matters. But we won’t claim they cure anything the evidence doesn’t support.
