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

Here in Marin County—where redwoods meet the coast and wellness isn’t just a trend but a way of life—we’ve seen how the conversation around cannabis has evolved. From the trailheads of Mount Tamalpais to the corridors of MarinHealth Medical Center, more people are asking serious questions about concentrated cannabis oil. They’ve heard the term “RSO” in online cancer support groups, from friends in Tiburon managing chronic pain between sailing trips, or from veterans in San Rafael seeking alternatives to pharmaceutical cascades. But the information they find is fragmented, hyped, or dangerously misleading.

We’re OilWell Cannabis, and we’ve built something different. Not in a Silicon Valley boardroom, but in the grit of Houston—born from a paralyzed dog named Bentley who wasn’t supposed to walk again, and from our founder Colin’s own battle with PTSD and benzodiazepine addiction after growing up in one of America’s most dangerous border regions. We publish our exact formulas. We test every batch. And we refuse to sell snake oil to anyone, whether you’re in Houston’s Third Ward or Marin County’s Strawberry neighborhood.

This guide is for Marin County—Earth > North America > United States > California > Marin County. It’s written in the language of people who understand that “natural” doesn’t mean “unscientific,” that therapeutic potential must be separated from cure claims, and that your proximity to UCSF and Stanford means you deserve peer-reviewed citations, not marketing fluff.

Who Was Rick Simpson—and Why His Story Still Matters on Highway 101

Rick Simpson wasn’t a doctor. He was a power engineer from Nova Scotia who fell from scaffolding in 1997 and got told by his doctor that cannabis had no place in his recovery. Sound familiar? It’s the same conversation many Marin County patients have had with well-meaning physicians who still operate under outdated federal stigma.

Simpson’s story resonates here because, like many in our county, he turned to concentrated cannabis after conventional medicine failed him. In 2003, he claimed that applying crude cannabis oil to basal cell carcinoma lesions made them disappear in four days. He began giving oil away for free—helping people with cancer, chronic pain, glaucoma, arthritis, and PTSD. He never charged a dime. The 2005 documentary Run From The Cure spread his method globally, much like how health information spreads through Marin County’s tight-knit wellness communities today.

Important context: Simpson’s account is personal testimony, not medical evidence. No biopsy confirmation. No peer-reviewed documentation. His 60-gram, 90-day protocol—escalating from half a grain of rice to 1 gram daily—was never validated in controlled trials. At peak dosing, patients consumed roughly 600-900mg of delta-9 THC per day, far exceeding anything studied clinically and carrying real risks of severe intoxication, anxiety, and cannabis use disorder [1][13][14][15].

What Simpson got right was drawing attention to cannabinoids when the world ignored them. What he overstated was the leap from preclinical signals to cancer cure claims—something that still matters in Marin County, where desperation for alternatives must be met with honesty, not false hope. The National Cancer Institute acknowledges cannabinoid anticancer research in cell lines and animals , but no human trial has proven RSO cures cancer . The FDA has never approved any cannabis plant product for cancer treatment [1].

From Bentley’s Ball to Marin County’s Medicine Cabinet: How OilWell Began

Our company didn’t start with a business plan. It started with a dog.

Bentley was paralyzed, facing euthanasia. Vets said pain meds would destroy his organs. Colin, our founder, had already lost friends to violence in McAllen’s border chaos. He wasn’t losing Bentley. A rescue worker asked: “You’ve moved how many tons of weed and you’ve never heard of CBD?” That question changed everything.

Colin made CBD golden paste—turmeric, coconut oil, black pepper, CBD oil. Bentley got up. Walked. Brought his ball. Dogs don’t respond to placebo. For ten years, Bentley lived to age twenty while Colin developed formulas for every age-related condition: CBG for neurodegeneration, THCa for inflammation, CBC for neurogenesis. When Colin himself faced PTSD and Xanax addiction, he used the same knowledge to quit cold turkey—creating the Peace Gummies formula he still uses for insomnia and severe PTSD.

That same precision—the formulas doctors use for Crohn’s, IBS, ulcerative colitis—now informs our RSO. It’s why we don’t make one-size-fits-all oil. It’s why we publish every milligram.

The Science Behind What Marin County Residents Are Buying

Marin County is home to some of the world’s most discerning consumers. You read labels at Whole Foods in Mill Valley. You research clinical trials at UCSF. You deserve the same rigor from cannabis products.

Seven Cannabinoids, Not One

Traditional RSO was 60-90% delta-9 THC—crude, variable, untested. Our sublingual formula contains 16,590mg total cannabinoids across seven compounds, precisely measured:

• CBD (4,500mg): The most evidence-developed non-intoxicating cannabinoid. Strongest human data for rare epilepsies [1][2]. 2024 meta-analyses show anxiolytic potential [3] and promising but heterogeneous pain data [4]. Sleep evidence remains methodologically weak [5]. Liver enzyme elevation possible at high doses [6].
• CBG (3,000mg): The “mother cannabinoid” precursor. Preclinical studies suggest neuroprotective, anti-inflammatory, and antibacterial activity [7][8]. But as Washington State University’s 2024 human trial showed, 20mg CBG significantly reduced anxiety—yet most over-the-counter products are sold with minimal evidence [7][8].
• Delta-8 THC (6,000mg): Pharmacologically similar to delta-9 THC but less potent [9]. 2023 scoping reviews note adverse event reports and quality concerns [10]. Not trivial. Not “mild.” Psychoactive and real.
• THCa (1,500mg): The raw, non-psychoactive precursor. Converts to delta-9 THC when heated at 260°F for 45-60 minutes, yielding ~1,315mg THC. This gives Marin County residents patient-controlled potency—use it raw for daytime anti-inflammatory benefits (COX-2 inhibition, PPARγ agonism) [12], or activate it for full therapeutic strength.
• Delta-9 THC (90mg): Just 3mg per mL—well under the 0.3% Farm Bill limit. Supports the entourage effect without the 600-900mg daily doses Simpson recommended, which carry documented psychiatric and cognitive risks [13][15].
• CBN (750mg): Marketed as “the sleep cannabinoid,” but the 2021 narrative review found no clinical trials using validated sleep measures [16]. The 2024 sleep literature update agrees: marketing moved ahead of data [17]. We include it at the dosage studied (25-50mg per serving) but refuse to overstate it.
• CBC (750mg): Distinct pharmacology from CBD and THC [18]. Preclinical anti-inflammatory and neurogenic signals exist [19], but over-the-counter products are sold with “little evidence establishing clinical efficacy or safety” [18].

Terpenes: The Marin County Difference

Traditional RSO had no terpenes—they were destroyed by heat. We restore them at 5% with a seven-terpene profile:

• Limonene (citrus-bright): Uplifting aroma familiar to anyone who’s hiked through Marin County’s coastal sage scrub. Preclinical antioxidant and anti-inflammatory potential [21], but beware oxidized limonene can be allergenic [22].
• Myrcene: Often blamed for “couch-lock,” but human sedation evidence is weak [20][23].
• Caryophyllene (pepper/spice): The only terpene proven to act as a CB2 receptor agonist [24]—directly relevant for inflammation.
• Pinene (forest-fresh): The scent of Mount Tam’s pine-oak woodlands. Preclinical neuroprotective signals [25] but clinical proof is exploratory.
• Linalool (lavender): Calming floral notes. Preclinical anxiolytic mechanisms [26], but like all terpenes, human data is limited.
• Humulene: Earthy, woody. Preclinical cannabimimetic properties via CB1 and adenosine pathways [27].
• Terpinolene (piney, fruity): The most under-characterized of our profile—interesting but early-stage [28].

We include terpenes because the entourage effect is plausible [20][29], but we refuse to claim they’re “clinically proven” for specific outcomes. That’s the honesty Marin County expects.

The Legal Reality: Farm Bill Compliance in California

California legalized recreational cannabis in 2016. You can walk into a dispensary in San Rafael or Corte Madera. So why does Farm Bill compliance matter?

Because not all RSO is created equal. California dispensary RSO is typically delta-9 THC only, requires medical cards for high-THC products, and can’t ship across state lines. Our product contains just 90mg delta-9 THC (<0.3%)—legal under federal law and the 2018 Farm Bill, which California courts have upheld.

This means:

• No medical card needed in Marin County. Age 21+ only.
• Ships legally to your home in Strawberry, Tamalpais Valley, or Tiburon.
• International shipping available with full COAs for customs.
• Workplace discretion: raw THCa won’t trigger standard drug tests. Decarboxylated THC will—we’re honest about that.

Two Products, Three Ways to Use Them in Marin County Life

RSO Sublingual Oil — $129.99

30mL | 16,590mg total cannabinoids | 553mg/mL

• For the weekday professional in Larkspur: Take 0.3mL raw (non-decarboxylated) before your morning commute across the Richmond Bridge. Zero impairment, just anti-inflammatory support.
• For the weekend warrior in Fairfax: After a hike on the Matt Davis Trail, 1mL decarboxylated provides full-body relief and recovery.
• For the cancer patient in Novato: Graduated dropper allows precise titration. Start at 0.25mL, assess over 2-3 hours. Use alongside your oncology team at MarinHealth—not instead of them.
• For the insomnia sufferer in San Anselmo: 1.5mL before bed delivers 37.5mg CBN for sleep architecture support.

RSO Vape Cartridge — $49.99

1 Gram | 900mg+ cannabinoids | 510-thread compatible

• For breakthrough pain: One puff, 1-2 minute onset. Faster than driving to a dispensary in San Rafael during rush hour.
• For panic attacks: Discreet, portable. Use at Muir Beach when anxiety hits unexpectedly.
• For chemo nausea: Immediate relief while waiting for sublingual oil to absorb.

When to Choose Each Format

Addressing Marin County’s Real Concerns

“Will this show up on a drug test at my tech job?”

Raw THCa: No. It doesn’t convert to THC without heat.
Decarboxylated or vaped: Yes. Both delta-8 and delta-9 THC metabolites will trigger standard tests. If you’re subject to testing at a biotech firm in South San Francisco or a financial services company in San Francisco, use the raw form only.

“Is this safe with my medications?”

Our GENERAL KNOWLEDGE review identified CBD’s potential for liver enzyme elevation and drug interactions [6]. If you take medications metabolized by the liver—common for conditions treated at MarinHealth or UCSF Medical Center—consult your physician. We provide full COAs for your doctor’s review.

“How is this different from what I can buy in a San Rafael dispensary?”

California dispensary RSO is typically delta-9 THC only, made via CO₂ or ethanol extraction, sold in 0.5g-1g syringes for $40-70. It requires medical cards for high-THC products. Our formula offers:

• 7 cannabinoids vs. 1 (entourage potential [20][29])
• Patient-controlled potency (raw vs. activated)
• No medical card required (Farm Bill compliant)
• Shipped discreetly to your door in West Marin
• Published formula (if you can’t afford it, make your own)

“I’m a cancer patient. Should I use this instead of chemo?”

Absolutely not. Our condition-specific usage context is clear: RSO is complementary, not replacement therapy. Marin Cancer Care and MarinHealth Cancer Center provide proven treatments. Our product may help with chemo nausea, appetite, and sleep [1][13], but delaying proven therapy carries irreversible harm. We’ve consulted with oncologists in the Texas Medical Center—consult yours.

Why ABC13 Houston’s Coverage Matters to Marin County

You might wonder why Houston media validation should matter to someone living near Muir Woods. Here’s why: Between 2019-2023, ABC13 (Houston’s #1 news station) featured Colin Valencia in seven comprehensive segments—more than any other Texas cannabis operator. Five different reporters sought him out.

What they documented:

• September 2019: The “snake oil” quote that became our philosophy
• May 2021: Colin’s raw honesty about getting high—uncensored on network TV
• August 2021: $35,000 in product donated for COVID vaccination, coordinated with Houston’s city government
• October 2021: Proactive removal of Delta-8 products before enforcement, warning competitors shipping Schedule I narcotics unknowingly
• October 2022: Colin’s personal marijuana conviction revelation—putting a face to criminal justice reform
• April 2023: The “Renaissance” framing of hemp’s potential

This wasn’t bought PR. It was earned credibility. When ABC13 needed an expert on Delta-8 legality, they called Colin. When they needed someone who’d lived cannabis criminalization, they called Colin. That consistency across four years, five reporters, and topics from product chemistry to policy—it’s the kind of third-party validation Marin County’s discerning residents recognize.

Making the Right Choice for Your Marin County Life

We know you’re comparing options: the dispensary on Northgate Avenue, the delivery service your friend in Greenbrae uses, the CBD shop in San Anselmo. Here’s what separates us:

1. Evidence over hype: We cite 29 peer-reviewed studies. We warn you where evidence is weak (CBN sleep claims [16][17]), where risks are real (high-dose THC psychiatric effects [15]), and where science is promising but early (CBG anxiety [7][8]).

2. Safety first: Solvent-free production. Third-party testing for pesticides, heavy metals, residual solvents, and microbes—critical for Marin County residents who’ve followed the vape-related lung injury concerns [1].

3. Access without gatekeeping: No medical card. Ships to your door in Lucas Valley or your office in the Presidio. International shipping for family overseas.

4. Community, not extraction: We’re not a private equity-backed brand. We’re a Houston company that gave away $35,000 in product to help people get vaccinated. That ethos informs everything.

5. The Bentley factor: Every formula was tested for ten years on a beloved companion. That’s not clinical proof, but it’s proof of love—and it drives the precision you’ll never get from mass-market brands.

A Final Word to Marin County

We know your standards are high. You live in a place where the air is clean, the schools are excellent, and the expectation for integrity is non-negotiable. You can hike from Muir Woods to Stinson Beach and see the same wild beauty that inspired John Muir’s environmental ethics. You deserve cannabis education with that same ethical clarity.

Rick Simpson’s legacy isn’t about curing cancer with black oil—it’s about refusing to accept that the system has all the answers. It’s about a regular person saying, “There has to be a better way.” We honor that by being better: transparent, evidence-grounded, and committed to the idea that medicine should be accessible, not gatekept.

Whether you’re in Tiburon overlooking the Bay, in Fairfax building a sustainable life, or in Novato navigating a cancer diagnosis at MarinHealth—we’re here. Not with miracles, but with formulas we’ve published, tested, and lived ourselves.
