Rick Simpson Oil (RSO) in Nevada County, Arkansas: The Complete Guide by OilWell Cannabis

For folks in Nevada County grappling with chronic pain, cancer treatment side effects, PTSD, or the kind of sleepless nights that make sunrise feel like a punishment, you’ve probably heard whispers about Rick Simpson Oil. Maybe a neighbor mentioned it at the Prescott diner. Maybe you saw it discussed in an online support group for Arkansas cancer patients. Maybe you’re just tired of driving two hours to Texarkana for another prescription that doesn’t work.

We’re OilWell Cannabis, and we’ve been where you are. Not in Nevada County specifically—we’re based in Houston’s Montrose neighborhood—but our roots run through the same hard soil. Our founder, Colin Valencia, grew up in McAllen, Texas, one of the most dangerous border regions in America. He learned early what it means to live in a place the world forgets, where healthcare is a privilege and self-reliance isn’t a hobby—it’s survival. That’s the same ethos we see in Nevada County’s farming communities, in the timber workers and small business owners who make up your 8,500-strong population. You don’t wait for solutions. You build them.

This guide is our promise to Nevada County: no snake oil, no false hope, just the most comprehensive, honest education about RSO available anywhere. We’ll tell you what Rick Simpson actually made, what the science really says, what’s legal in Arkansas, and how our formulas—which we’ve published open-source below—might fit into your life. We’ll reference your local context: the limited healthcare access, the agricultural heritage that makes you understand plant medicine, and the conservative legal environment that demands we get this right.

What Is Rick Simpson Oil, Really?

Rick Simpson wasn’t a doctor. He was a power engineer from Nova Scotia who got hurt on a job in 1997, suffered a head injury, and found that cannabis gave him relief when prescriptions didn’t. In 2003, he claimed cannabis oil removed three basal cell carcinoma bumps on his arm in four days. He never published medical proof, but he did something revolutionary: he started giving oil away for free to cancer patients, documenting testimonials, and teaching others how to make it.

The traditional RSO protocol is brutally simple: 60 grams of thick, black, tar-like cannabis oil over 90 days. Simpson recommended starting with a dose the size of half a grain of rice, three times daily, and doubling every four days until you’re taking a full gram per day. At that peak dose, you’re consuming 600–900 mg of delta-9 THC daily—far beyond anything studied clinically.

Important context: This protocol was never validated in controlled trials. The starting material was whatever indica strain someone grew, extracted with naphtha (lighter fluid) or isopropyl alcohol in a rice cooker. No lab testing. No standardization. Every batch different. Real risks at those THC doses include severe intoxication, anxiety, tachycardia, and cannabis use disorder [1][13][14][15].

Yet Simpson’s legacy is undeniable. He created the political and cultural space for legal cannabis research to exist. He gave the world a term—RSO—that remains the most recognized name for full-spectrum cannabis extract . He operated from desperation, not greed. And at OilWell, we respect that origin while solving the problems he couldn’t.

The OilWell Origin: A Dog Named Bentley and a Man Who Refused to Give Up

Our story doesn’t start in a corporate boardroom. It starts with a paralyzed dog named Bentley facing euthanasia. In 2019, our founder Colin’s veterinarian said Bentley’s pain meds would destroy his organs. The humane choice was putting him down. Colin had moved tons of cannabis in his life, but he’d never heard of CBD until a rescue worker named Jessica asked: “You’ve moved how many tons of weed and you’ve never heard of CBD?”

That question changed everything.

Colin made Bentley CBD golden paste—a recipe we still publish for free so any Nevada County pet owner facing a similar crisis can try it. Bentley got up. Walked. Brought Colin his ball. This wasn’t placebo—dogs don’t respond to placebo. This was cannabinoid medicine doing what pharmaceuticals couldn’t.

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

• Neurodegeneration → CBG (cannabigerol) for neuroprotection, THCa for PPARγ agonism in brain cells
• Dementia → CBC (cannabichromene) for neurogenesis
• Glaucoma → THC for CB1-mediated intraocular pressure reduction
• Arthritis → Multi-pathway anti-inflammatory approach: CBD, CBG, THCa, and beta-caryophyllene targeting different receptor systems simultaneously

Single cannabinoids weren’t enough. Bentley’s evolving conditions required seven-cannabinoid synergy. That necessity—keeping a loved companion alive—became the foundation of our RSO formula.

Colin also knows pharmaceutical dependence personally. He quit Xanax cold turkey using the same cannabinoid knowledge that saved Bentley. He created our Peace Gummies during midnight experiments while fighting benzo withdrawal. He personally uses our vape form for insomnia and severe PTSD. This isn’t theoretical. He lived what RSO patients live: desperation for relief, failed prescriptions, discovering cannabinoids work when pills don’t.

Why Nevada County Matters: Rural Arkansas Healthcare and the Cannabis Alternative

We understand Nevada County. Your county seat is Prescott, population 3,200. You’ve got the Nevada County Hospital, but for oncology, chronic pain specialists, or PTSD treatment, you’re driving to Texarkana, Little Rock, or Shreveport. That’s hours on the road, gas money, time off work you can’t afford.

Arkansas legalized medical cannabis in 2016, but the program is restrictive. To qualify, you need a medical card and a condition like cancer, PTSD, or chronic pain. Even then, your nearest dispensary might be in Hope or Magnolia—still a significant drive. For many in rural Arkansas, access remains theoretical.

That’s where the 2018 Farm Bill changes everything. Hemp-derived cannabinoids containing less than 0.3% delta-9 THC are federally legal and legal in Arkansas. Our RSO products are hemp-derived and Farm Bill compliant at the point of sale. You don’t need a medical card. You just need to be 21+. We ship directly to Nevada County via USPS Priority Mail (2-3 business days), discreetly packaged with no cannabis branding.

Legal notice: THCa converts to delta-9 THC when heated. Arkansas law focuses on delta-9 THC content at point of sale, which our products meet. You’re responsible for understanding local laws regarding possession and use. We provide full Certificates of Analysis (COAs) and receipts for every order.

The Science: What Each Cannabinoid Actually Does

Our formula contains seven cannabinoids at specific ratios. Here’s what peer-reviewed research says about each—because you deserve honest evidence, not marketing hype.

CBD (4,500 mg in sublingual oil)

• Best evidence: Seizure disorders. The FDA approved Epidiolex for rare epilepsies based on robust clinical trials [1][2].
• Anxiety: A 2024 meta-analysis of 316 participants found significant anxiolytic effects, but authors stress the clinical sample is limited [3].
• Pain: 2024 systematic review calls results “promising but heterogeneous”—trial quality limits confidence [4].
• Sleep: 2023 insomnia review found literature “methodologically weak” with few objective assessments [5].
• Safety: 2023 meta-analysis found real signals for liver enzyme elevation and drug-induced liver injury, especially concerning for concentrated oral products [6].
• Bottom line: CBD has the strongest non-psychoactive evidence, but it’s not a cure-all. It works for specific conditions, modestly for others, and carries liver interaction risks.

CBG (3,000 mg)

• Evidence: Primarily preclinical. 2021 pharmacology review notes CBG interacts with cannabinoid receptors, alpha-2 adrenoceptors, and 5-HT1A signaling [7].
• Potential areas: Neurologic disorders, inflammatory bowel disease, antibacterial activity—all hypotheses from animal/in vitro work [7][8].
• 2024 review: “CBG has distinct pharmacodynamics” but “over-the-counter products are sold despite little evidence establishing clinical efficacy or safety” [8].
• Bottom line: CBG is scientifically credible but clinically immature. We’re including it for its potential in neuroprotection—something Colin saw work for Bentley—but we won’t overstate the evidence.

Delta-8 THC (6,000 mg)

• Evidence: 2022 review found delta-8 and delta-9 have “broadly similar pharmacokinetic and pharmacodynamic behavior,” but delta-8 is less potent [9].
• Public health: 2023 scoping review noted adverse consequences and emphasized manufacturing quality concerns [10].
• Our take: This is not “diet THC.” It’s psychoactive and real. We’re transparent: you will feel this. For Nevada County residents sensitive to THC’s anxiety effects, start with the raw (non-decarbed) option.

THCa (1,500 mg) – The Game-Changer

• What it is: The acidic precursor to delta-9 THC. Non-psychoactive in its raw form.
• Evidence: Preclinical work suggests anti-inflammatory (COX-2 inhibition) and neuroprotective (PPARγ agonism) potential [12].
• Why it matters for Nevada County: You can use this product raw during the day—no impairment, safe to drive, functional for work—then decarb a small amount at night for full psychoactive relief. Patient-controlled potency. You decide, not us.
• Conversion math: Heat at 260°F for 45-60 minutes converts 1,500 mg THCa → ~1,315 mg delta-9 THC. Combined with existing 90 mg delta-9, you get ~1,405 mg total delta-9 THC—comparable to illegal RSO, but legal because you activate it after purchase.

Delta-9 THC (90 mg)

• Evidence: Strongest for chemotherapy nausea, HIV/AIDS appetite, and some pain [1][13].
• Pharmacokinetics: Inhaled: onset in seconds, peak 15-30 min, duration 2-4 hours. Oral: onset 30-90 min, peak 2-4 hours, duration 4-8+ hours [14].
• Risks: 2025 review of high-concentration THC products found “consistent unfavorable associations with psychosis, schizophrenia, and cannabis use disorder” [15]. Anxiety, tachycardia, impaired driving at high doses [1][14].
• Our approach: Only 90 mg in the whole bottle (3 mg/mL) when raw. That’s intentional. We give you THCa to activate at your discretion, not force high delta-9 exposure.

CBN (750 mg)

• Evidence: Weak for sleep. 2021 review screened 99 human-study abstracts and found no clinical trials using validated sleep questionnaires or polysomnography [16].
• Marketing vs. reality: CBN’s reputation as a sleep aid outruns the data. We’re transparent: we’re including it because of its theoretical potential and because customers request it, but we won’t claim it’s clinically proven for sleep.
• Dosing: At 2 mL, you get 50 mg CBN—matching the dosage studied in 2024 sleep literature [17]. At 1 mL, 25 mg—above the 20 mg threshold associated with reduced sleep disturbance in some research.

CBC (750 mg)

• Evidence: 2024 review found “distinct pharmacodynamics” and potential for antinociceptive and antibacterial effects, but stressed products are “sold despite little evidence establishing clinical efficacy or safety” [18].
• Preclinical: Anti-inflammatory, reduced gut hypermobility, possible neurobiological relevance [19].
• Bottom line: Another promising minor cannabinoid that deserves more research. We’re formulating ahead of the curve, but honestly about where the evidence stands.

The Terpenes: More Than Aroma

Our 5% live terpene profile includes seven terpenes. Here’s what science says:

• Limonene: Multi-functional monoterpene with antioxidant and anti-inflammatory properties in non-cannabis literature [21]. Oxidized limonene can be a contact allergen [22].
• Myrcene: Anxiolytic and anti-inflammatory in animal models, but “human studies are lacking” [23].
• Caryophyllene: The standout. Direct CB2 receptor agonist—unusual for a terpene [24]. Anti-inflammatory, neuroprotective potential.
• Pinene & Linalool: “Antioxidant, anti-inflammatory, neuroprotective signals” but “well-designed clinical trials are lacking” [25]. Linalool may have antidepressant mechanisms [26].
• Humulene: Preclinical evidence for anti-inflammatory and possible cannabimimetic effects via CB1 and adenosine A2a [27].
• Terpinolene: Least clinically characterized. 2021 review: evidence “dominated by in silico, in vitro, and animal studies” [28].

The entourage effect: Real but unproven in humans. The 2024 comprehensive review found “robust proof of clinically meaningful entourage effects remains limited” [20][29]. We include terpenes because they’re plausible and improve the experience, not because we can claim proven synergy.

Media Recognition: Why ABC13 Keeps Coming Back

Between 2019-2023, ABC13 Houston featured us seven times across five different reporters. They didn’t come because we paid for PR. They came because when Texas needed to understand Delta-8 legality, when a president pardoned cannabis convictions, when COVID needed community response—we were the credible voice.

What this means for Nevada County: You can verify everything we claim. Watch Colin say, “I’m not trying to sell people snake oil” on ABC13’s broadcast. See the COVID giveaway coverage. Witness the Delta-8 ban response where Colin proactively removed products and warned competitors. This is third-party validation you can trust.

Key moments:

• 2019: First feature where Colin established the “no snake oil” philosophy
• 2021: Delta-8 investigation—Colin’s blunt honesty: “Maybe you want to get high”
• 2021: $35,000 in free product for COVID vaccination—community health leadership
• 2021: Delta-8 banned overnight—Colin removed products before enforcement, warned other operators
• 2022: Biden pardon feature—Colin revealed personal cannabis conviction history, showing he’s not an outsider looking in

The through-line: Consistency, breadth, community action, personal stakes. ABC13’s editorial judgment is the credibility that money can’t buy.

Addressing Nevada County’s Specific Concerns

The Opioid Crisis in Rural Arkansas

Arkansas has one of the highest opioid prescription rates in the nation. Nevada County residents know the cycle: injury → prescription → tolerance → dependency → devastation. Our formula offers an alternative. The delta-8 THC provides pain relief without the respiratory depression of opioids. The CBG and THCa address inflammation through multiple pathways. The CBD can help with withdrawal anxiety. We’re not saying “stop your prescriptions tomorrow.” We’re saying: here’s a tool that helped Colin quit Xanax cold turkey, that helps veterans with PTSD, that might help you taper responsibly under medical supervision.

Cancer Support in a Rural County

If you’re undergoing chemo at the Nevada County Hospital or traveling to Texarkana for treatment, you need relief that travels with you. Our sublingual oil is TSA-friendly (Farm Bill compliant) for flights to MD Anderson. The vape provides instant nausea relief in the parking lot before treatment. The CBN helps with post-chemo insomnia. We are not a cancer cure—we’re explicit about that. But we can help with the side effects that make treatment bearable.

Agricultural Heritage Meets Plant Medicine

Nevada County’s economy runs on agriculture and timber. You understand plants. You know that not every plant medicine is “snake oil”—you’ve seen willow bark work for pain, you know herbal remedies passed down generations. Cannabis is a plant, but it’s also precise chemistry. Our open-source formulas are like a seed catalog: here’s exactly what’s in it, here’s how to grow your own if you want. That transparency respects your knowledge.

The Medical Desert Reality

The nearest comprehensive cancer center is hours away. The pain clinic waitlist is months long. Our same-day shipping to Nevada County means you don’t wait. You order Monday, it’s in your mailbox Wednesday. You have questions about drug interactions? Call us. We’ll talk through your meds (we know about CYP450 enzyme interactions, about blood thinners, about seizure thresholds). We’ll tell you if we think it’s risky. We’ll tell you to consult your doctor—because we know Nevada County’s Dr. Hargis or NP at the hospital is stretched thin, but they’re still your medical home.

Safety: What Nevada County Needs to Know

• Liver enzymes: CBD can elevate liver enzymes, especially with high doses or combined with alcohol, acetaminophen, or other hepatotoxic drugs [6]. If you’re a hardworking Arkansas farmer who enjoys a beer after a long day, be aware.
• Drug tests: Delta-8 THC and activated THCa will cause positive THC tests. Raw THCa will not. If your employer in Prescott or Hope drug tests, use the raw option or disclose your use.
• Pregnancy: Not recommended. Arkansas has high maternal mortality rates; we won’t add risk.
• Driving: Don’t. Not after decarbed doses. Nevada County’s sheriff deputies have enough to handle without impaired drivers.
• Pediatric exposure: Keep products locked up. Our packaging is child-resistant, but Arkansas kids are curious.

The Bottom Line for Nevada County

We didn’t build this company to get rich. We built it because Bentley got up. Because Colin couldn’t breathe without Xanax until cannabis gave him his life back. Because we’ve seen what desperation looks like, and we’ve seen what relief looks like.
