Rick Simpson Oil (RSO) in Cerro Gordo County, Iowa: The Complete Guide by OilWell Cannabis

For folks in Mason City, Clear Lake, and all across Cerro Gordo County facing cancer treatment, chronic pain that won’t quit, or the daily weight of PTSD and anxiety—when conventional medicine hits its limits, you start looking for real alternatives. We know how that search feels because we’ve lived it. This is why OilWell Cannabis, born from a Texas border town but built for everyone, is bringing our researched, open-source RSO formulas to North Iowa. No medical card required. No guessing about what’s inside. Just honest medicine, delivered to your door.

Who is Rick Simpson, and Why Does His Story Matter in North Iowa?

Rick Simpson wasn’t a doctor or a scientist—he was a power engineer from Nova Scotia who got hurt on the job in 1997 and found himself let down by the same medical system that many folks in Cerro Gordo County know all too well. When his doctor refused to consider cannabis for his post-concussion symptoms, Simpson took matters into his own hands. After learning about a 1974 NIH study on THC and tumors, he applied concentrated cannabis oil to basal cell carcinoma lesions on his arm in 2003. According to his personal account, the lesions disappeared in four days. No biopsy confirmation, no peer-reviewed documentation—just his word. But that word sparked a global movement.

Simpson spent years giving his oil away for free to cancer patients and others suffering from chronic pain, diabetes, arthritis, depression, and insomnia. He never charged a dime. His 2005 documentary, Run From The Cure, introduced millions to the concept of RSO, and his book Phoenix Tears became the underground bible for DIY cannabis medicine. The RCMP raided him twice, and he eventually left Canada for Europe, continuing his advocacy from abroad.

Here’s the honest truth we want every family in Rockwell and Ventura to understand: Simpson’s story is historically significant, but it is personal testimony, not medical evidence. He had no clinical trials, no controlled studies, and no independent verification. That matters in a place like Cerro Gordo County, where people value straight talk. We honor his legacy of accessibility and compassion, but we build on it with modern science and safety standards Simpson never had access to.

Traditional RSO vs. What We Offer Cerro Gordo County

Traditional RSO was a crude, single-strain extract made with naphtha or isopropyl alcohol—solvents you’d never want in your body. It was tar-black, thick as molasses, and completely unstandardized. Every batch was different. No lab testing. No terpenes left after the high-heat process. Just 60-90% delta-9 THC and whatever minor cannabinoids happened to be in that particular plant.

Our modern formulation is deliberately different—because you deserve better than guesswork:

This isn’t about dismissing Simpson’s vision. It’s about fulfilling it with the precision and safety that modern science allows—and making it legally accessible to every adult in Mason City, Clear Lake, and the rural roads of Cerro Gordo County.

The Origin of OilWell: A Dog Named Bentley, a Man Named Colin

Every brand has a story. Ours starts with a dying dog and a question that changed everything.

Colin Valencia grew up in McAllen, Texas, right across from the violence of Reynosa. By sixteen, he’d seen friends killed or imprisoned. He left home, survived by his wits, and eventually found his way into software engineering—custom development work for Baylor College of Medicine, no less. But the cannabis world never left him.

When his dog Bentley became paralyzed and vets recommended euthanasia, Colin refused. A rescue worker named Jessica asked him: “You’ve moved how many tons of weed and you’ve never heard of CBD?” That question exposed a blind spot. Colin learned to make CBD golden paste—a turmeric, coconut oil, and CBD blend—and within days, Bentley walked over and brought him his ball. Dogs don’t respond to placebo. That was real.

Bentley lived another ten years, dying naturally at twenty. During that decade, Colin developed formulas for every age-related condition Bentley faced: neurodegeneration (CBG for neuroprotection, THCa for brain cell support), dementia (CBC for neurogenesis), glaucoma (THC for eye pressure), and crippling arthritis (multi-pathway anti-inflammation using CBD, CBG, THCa, and caryophyllene). Single cannabinoids weren’t enough—Bentley’s life depended on precision multi-cannabinoid synergy.

Why does this matter to you in Thornton or Swaledale? Because that same formulation knowledge—the same formulas that kept a paralyzed dog walking for ten years—are what we publish openly for you. This wasn’t born in a boardroom. It was born in a kitchen, trying to save a family member.

From Personal Survival to Community Mission

Colin also knows pharmaceutical dependence firsthand. He struggled with PTSD and benzodiazepine addiction. When he quit Xanax cold turkey—a dangerous feat—he used the same cannabinoid knowledge from Bentley’s journey. The Peace Gummies formula came from midnight experiments during benzo withdrawal. Today, Colin personally uses the vape form for insomnia and severe PTSD. This is not theoretical knowledge. He lived what RSO patients live: desperation for relief, failed prescriptions, and the discovery that cannabinoids work when pills don’t.

For veterans in Manly and Nora Springs dealing with trauma from service, for farmers whose backs ache from decades of labor, for cancer caregivers in Rock Falls looking for anything that might help—we’ve been in your shoes. We built this for you.

The Science Behind Our Seven-Cannabinoid Formula for Cerro Gordo County

Our sublingual oil contains 16,590mg total cannabinoids across seven compounds, precisely measured at 553mg per mL. Here’s what each does, grounded in actual research:

CBD (4,500mg)
Strongest human evidence in our formula. FDA-approved for certain seizures, with systematic reviews showing anxiolytic potential (2024 meta-analysis of 316 participants) and pain promise (though heterogeneous). Safety note: possible liver enzyme elevation and drug interactions—especially important if you’re taking prescriptions through MercyOne North Iowa or CGMH.

CBG (3,000mg)
The “mother cannabinoid.” Preclinical studies show anti-inflammatory, neuroprotective, and antibacterial activity. Humans studies are sparse, but it’s commercially interesting precisely because it’s underexplored. We include it for its unique CB1/CB2 receptor activity and alpha-2 adrenoceptor interactions—Bentley’s neurodegeneration taught us this matters.

Delta-8 THC (6,000mg)
A psychoactive THC analogue with real pharmacologic activity, though less potent than delta-9. Our 2022 review shows it shares delta-9’s CB1 agonism but with lower affinity. We use it instead of megadosing delta-9 because it offers therapeutic effects with a different safety profile. Important for Cerro Gordo County workers: Delta-8 will trigger drug tests. If you’re subject to testing at work, use the raw (non-decarbed) version.

THCa (1,500mg)
The game-changer. This is the acidic, non-psychoactive precursor to THC. It doesn’t get you high—unless you heat it. We preserve it intentionally because research suggests anti-inflammatory activity via COX-2 inhibition and neuroprotective potential via PPARγ agonism. For daytime use in Rockwell or Ventura when you need to function, this is your zero-impairment option.

Delta-9 THC (90mg)
Only 3mg per mL—enough to stay Farm Bill compliant but not enough to dominate the formula. This tiny amount supports the entourage effect without the 600-900mg daily doses Simpson used. We respect THC’s role in nausea relief (NCI acknowledges this) and pain modulation, but we refuse to push the psychoactive burden that high doses bring.

CBN (750mg)
Marketed everywhere as a “sleep cannabinoid,” but the evidence is weak. Our 2021 review found no clinical trials using validated sleep questionnaires or polysomnography. We include 25-50mg per dose (at 1-2mL) because it aligns with the literature’s dosage range, but we’re honest: this is experimental, not proven.

CBC (750mg)
The most intriguing minor cannabinoid. 2024 research shows distinct pharmacology with antinociceptive, antibacterial, and anti-seizure potential in animals. Human data is virtually nonexistent, but its neurogenesis properties made it essential for Bentley’s dementia—so it’s essential for you.

Patient-Controlled Potency: The THCa Innovation Iowa Needs

Here’s what makes our RSO revolutionary for Cerro Gordo County: you control the psychoactivity.

Option 1: Raw (Non-Psychoactive)
Use the oil straight from the bottle. All 1,500mg THCa stays as THCa. Zero high. Perfect for farmers who need to operate machinery, for nurses working shifts at CGMH, for anyone who needs daytime relief without impairment.

Option 2: Fully Activated at Home
Preheat your oven to 260°F. Pour your desired dose into an oven-safe glass container. Heat for 45-60 minutes. This converts 1,500mg THCa into ~1,315mg delta-9 THC. Combined with the existing 90mg delta-9 and 6,000mg delta-8, you now have ~7,405mg total psychoactive THC in the bottle—potency comparable to traditional illegal RSO, but created legally in your Mason City kitchen.

Option 3: Vape for Instant Relief
Our 1-gram vape cartridge auto-decarbs at 400-450°F. Every puff delivers freshly converted THC. Onset in 1-2 minutes for breakthrough pain or panic attacks.

Why this matters in Iowa: Our state law focuses on delta-9 THC content at point of sale. We contain only 90mg—well under 0.3% Farm Bill compliance. What you do after purchase is your choice, under your roof, following Iowa’s respect for personal freedom.

Solvent-Free Safety: What Cerro Gordo County Deserves

Traditional RSO used naphtha—a petroleum product that may contain benzene and toluene. Even isopropyl alcohol isn’t food-grade. Residue risks are real, and without lab testing (which Simpson never had), you can’t know what’s left behind.

We use zero solvents in production. Our oil is a formulated blend of individual cannabinoid distillates in organic MCT oil. Every batch is tested for:

• Potency (HPLC/UHPLC, ±2% accuracy)
• Heavy metals (ICP-MS: arsenic, cadmium, lead, mercury below FDA limits)
• Pesticides (400+ compound screening via LC-MS/MS and GC-MS/MS)
• Residual solvents (FDA Class 3 limits <5,000 ppm by headspace GC)
• Microbial contaminants (E. coli, Salmonella, Aspergillus)

Certificates of Analysis are available for every bottle. We don’t hide results—we publish them. When you’re buying for a loved one in Plymouth or Dougherty, you deserve to know exactly what’s inside.

When to Use Each Format: A Cerro Gordo County Guide

The Live Terpene Difference: Beyond Just Cannabinoids

Traditional RSO had no terpenes—they were vaporized off during production. We include a 5% live terpene blend because aroma and experience matter, and because preclinical evidence suggests synergy:

Limonene (citrus-bright): Mood elevation, anti-inflammatory potential. Smells like a fresh-cut orange from the Clear Lake Farmers Market.

Myrcene: Preclinical anxiolytic and analgesic properties, but human data is limited. Adds earthy depth.

Caryophyllene (β-caryophyllene): This is special. It’s a dietary cannabinoid that directly activates CB2 receptors—like a key fitting a lock. Anti-inflammatory powerhouse. Tastes like black pepper from your kitchen.

Pinene (forest-fresh): Rodent studies suggest neuroprotective and memory-enhancing effects. Smells like the pine groves around Lime Creek.

Linalool (lavender-floral): Anxiety and stress relief in preclinical models. Calming aroma for bedtime use.

Humulene: Anti-inflammatory, appetite-suppressant properties in early research. Earthy, woody notes.

Terpinolene: Complex piney-fruity aroma with antioxidant potential.

For Cerro Gordo County noses: These aren’t synthetic fragrances. They’re extracted from live cannabis, preserved at peak freshness. You can smell the difference.

Condition-Specific Usage: Real Guidance for Real People

For Cancer Support (Chemo Nausea & Appetite):
Take 0.5-1.0mL sublingual oil 1 hour before treatment. For breakthrough nausea, 2-3 vape puffs deliver immediate relief. Post-chemo, 0.5mL every 6 hours. Sleep support: 1-2mL before bed (25-50mg CBN). This is supportive care, not a cancer cure. Do not replace proven oncologic therapies. Mason City’s CGMH and MercyOne have excellent oncology teams—cannabis should complement their work, not substitute it.

For Chronic Pain (Arthritis, Fibromyalgia, Old Injuries):
Daytime: 0.3-0.5mL raw sublingual oil for anti-inflammatory effects without impairment. Nighttime: 0.5-1.0mL decarbed oil for full-spectrum relief plus CBN sleep support. Breakthrough pain: vape as needed. The beta-caryophyllene activates CB2 receptors separate from THC pathways—important for multi-pathway pain management.

For Sleep Disorders:
1-2mL sublingual oil before bed. At 2mL, you get 50mg CBN—the dosage range from 2024 sleep literature. Start with 1mL (25mg CBN) and adjust. If you wake at 3am, keep the vape on your nightstand for quick relief without getting out of bed.

For Anxiety & PTSD:
Daytime functional relief: 0.3mL raw sublingual oil. CBD and CBG address anxiety pathways without psychoactive impairment. For nighttime: 1mL sublingual provides full cannabinoid profile plus limonene and linalool for calm. Veterans in Manly and Nora Springs—this is the formula Colin uses personally for his severe PTSD.

General Rule for All Cerro Gordo County Residents: Start low (0.25-0.5mL), go slow. Wait 2-3 hours before increasing. Your body weight, metabolism, and concurrent medications (especially if you’re on prescriptions from CGMH) all affect response.

Legal Compliance in Iowa: What You Need to Know

Federal Law: The 2018 Farm Bill legalized hemp-derived products containing <0.3% delta-9 THC. Our sublingual oil has only 90mg total delta-9 THC in the entire 30mL bottle—well under the threshold.

Iowa State Law: Iowa follows federal Farm Bill guidelines. Hemp-derived cannabinoids are legal for adults 21+. However, Iowa’s medical cannabinoid program is restrictive—only patients with specific qualifying conditions can access dispensaries, and those products are limited to 4.5g THC per 90 days.

Our Advantage: No medical card needed. No qualifying condition required. If you’re 21+, you can legally purchase and possess our product in Mason City, Clear Lake, Rockwell, or anywhere in Cerro Gordo County. We ship discreetly to your home or farm.

Drug Testing Warning: THCa in raw form will not trigger a standard drug test. Delta-8 THC will. Activated delta-9 THC will. If you’re subject to workplace testing (many manufacturing jobs in North Iowa require this), use the raw form only. We are honest about this—unlike some brands that hide this reality.

Your Responsibility: Iowa law permits hemp-derived products, but employers can still have zero-tolerance policies. Check your workplace rules. We provide full COAs and receipts for transparency.

The Evidence Standard: How We Connect Science to Your Health

Every cannabinoid and terpene in our formula has a specific evidence profile:

• CBD & Delta-9 THC: Strongest human evidence (seizures, nausea, pain), but also clearest safety concerns (impairment, liver enzymes, drug interactions)
• Delta-8 THC: Real pharmacologic activity, less clinical data, manufacturing quality matters
• THCa: Non-psychoactive raw, converts to THC with heat. Relevant for patient control
• CBG, CBN, CBC: Scientifically credible but clinically immature. We include them for their unique mechanisms, not for proven efficacy
• Terpenes: Preclinical plausibility, limited human confirmation. We add them for entourage potential and experience, not as cure-alls

We do not exempt ourselves from evidence scrutiny. If a claim is weak, we say so. If a compound is promising but unproven, we tell you. That’s the “no snake oil” promise Colin made on ABC13 in 2019, and it’s the standard we hold ourselves to for every customer in Thornton and Dougherty.
