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

If you’re reading this in Grundy County—whether you’re in Grundy Center, Conrad, Dike, or out in the rural stretches between our tight-knit communities—you’ve likely heard whispers about Rick Simpson Oil. Maybe someone at the Grundy County Memorial Hospital mentioned it. Maybe a neighbor farming the fertile Iowa prairie shared their experience. Or maybe you’re sitting in your kitchen in Reinbeck, researching alternatives after conventional medicine left you with more questions than answers.

We get it. We’ve been there. And we’re here to give you the most honest, comprehensive RSO education available anywhere—tailored specifically for Grundy County.

Who is Rick Simpson, and Why Does His Story Matter to Grundy County?

Rick Simpson wasn’t a doctor. He wasn’t a scientist. He was a power engineer from Nova Scotia—a tradesman, a blue-collar worker, not unlike many folks here in Grundy County who’ve built their lives around honest work and practical know-how. His journey into cannabis medicine started the way so many medical journeys do: the system failed him, and he got desperate.

In 1997, Simpson suffered a serious head injury from a scaffolding fall. The aftermath—persistent tinnitus, dizziness, post-concussion symptoms—wasn’t something his doctors could fix. The medications they prescribed either didn’t help or made things worse. When he asked his physician about cannabis, they dismissed it.

Sound familiar? In Grundy County, where we pride ourselves on self-reliance but also respect our medical institutions, there’s a quiet frustration when the system runs out of answers. Whether it’s chronic pain from years of farm work, the exhaustion of caring for aging parents in Shell Rock, or the anxiety that creeps in during those long Iowa winters—sometimes the standard treatments just don’t cut it.

Simpson’s pivotal moment came in 2003 when he claimed that applying concentrated cannabis oil to basal cell carcinoma lesions on his arm made them disappear in four days. Important context: no doctor verified this, no biopsy confirmed it, and no clinical study documented it. It was his personal testimony, not medical evidence. But that experience became the origin story for what we now call Rick Simpson Oil.

The Traditional RSO Protocol: What It Is and Why We Need to Talk Honestly About It

Simpson created a specific regimen that spread worldwide: 60 grams of oil over 90 days. Here’s exactly what that looked like:

Week 1: Start with a dose the size of half a grain of rice—about 10-15mg—three times daily. That’s roughly 30-45mg per day total.

Weeks 2-5: Double the dose every four days, slowly building tolerance to THC’s psychoactive effects. By week five, you’re taking approximately 1 gram (1,000mg) per day, split into three doses of about 333mg each.

Weeks 5-12: Maintain that 1 gram daily dose until you’ve consumed all 60 grams.

Sounds straightforward, right? But here’s the critical context that matters for Grundy County:

• No clinical trials ever validated this protocol. Not one.
• No standardization. Traditional RSO used whatever high-THC indica strain was available—potency varied wildly.
• Extremely high THC exposure. At peak dosing, that’s roughly 600-900mg of delta-9 THC per day. For perspective, the FDA’s synthetic THC drug dronabinol is typically dosed at 2.5-20mg per day. We’re talking about doses that have never been studied in controlled human trials.
• Real risks at those doses: severe intoxication, anxiety, panic, tachycardia, cannabis use disorder. These aren’t hypotheticals—they’re documented in the literature[1][13][14][15].
• Residual solvents. Traditional RSO was made with naphtha (lighter fluid) or 99% isopropyl alcohol—none of which are food-grade. Without lab testing (which didn’t exist in the underground market), there’s no way to know if harmful solvent residues remained.

In Grundy County, where we value safety and practicality, this information matters. We can’t gloss over these realities just because the story is compelling. People here deserve honesty, not hype.

What Traditional RSO Actually Was (The Product Specs)

Traditional RSO was:

• Source material: Single, unstandardized indica-dominant cannabis strains
• Extraction: Naphtha or isopropyl alcohol in a rice cooker
• Appearance: Nearly black, thick, tar-like oil with possible solvent-residual smell
• Cannabinoid profile: 60-90% delta-9 THC (estimated, never lab-verified), with minor cannabinoids at whatever natural ratios the strain had
• Terpenes: Effectively zero—destroyed by heat and solvent
• Standardization: None. Every batch was different.
• Testing: None. No Certificates of Analysis, no contaminant screening.

If you’ve seen “RSO” on a shelf in Iowa, chances are it bears little resemblance to what Simpson actually made. The term has become generic, like “Kleenex” for tissues.

How We Diverge From Traditional RSO (And Why It Matters for Grundy County)

OilWell’s RSO is not traditional RSO. We’ve deliberately evolved the formula based on what the evidence actually shows—not what we wish it showed. Here’s the comparison that matters for your decision-making:

Why We Publish Our Formulas (The Open-Source Promise)

Rick Simpson gave his oil away for free. He taught people how to make it because he believed medicine shouldn’t be locked behind corporate gates. We share that ethos, but we’ve adapted it for 2025.

We publish our complete formulas publicly—every cannabinoid, every milligram, every terpene percentage. If you can’t afford our products (we get it, farming in Iowa has tight margins), you can see exactly what’s in them and source the ingredients yourself.

This isn’t marketing. This is the same principle that saved Bentley.

Bentley’s Story: The Real Reason We Exist

Bentley was Colin’s dog—family, not a pet. When Bentley became paralyzed, vets said euthanasia was the only humane option. The pain meds would destroy his organs, they said. Colin refused to accept that.

A rescue worker named Jessica asked him: “You’ve moved how many tons of weed and you’ve never heard of CBD?” That question changed everything.

Colin created a CBD golden paste. Bentley got up. He walked over and brought Colin his ball to play. From paralyzed to playing fetch. Dogs don’t respond to placebo. That was real.

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

• Neurodegeneration → led to CBG’s neuroprotective properties
• Dementia → led to CBC’s role in neurogenesis
• Glaucoma → led to THC’s CB1 agonism for eye pressure
• Arthritis → led to multi-pathway anti-inflammatories (CBD, CBG, THCa, caryophyllene)

Single cannabinoids weren’t enough. Bentley needed seven. That’s why our RSO has seven. It wasn’t a marketing decision—it was born from necessity and love.

Our Four Core Principles (What Makes OilWell Different)

1. Accessibility Over Gatekeeping

No medical card required. In Iowa, where our medical cannabis program is one of the most restrictive in the country (only about 10,000 active patients compared to Florida’s 700,000), that’s a big deal. If you’re in Grundy County dealing with chronic pain, PTSD, or insomnia, you don’t need to wait for the state to decide you qualify. You’re 21 or older? You can order.

We ship nationwide and internationally. That means whether you’re in Grundy Center, Reinbeck, or anywhere in Iowa’s 4th Congressional District, you can access the same product someone in Houston gets—delivered discreetly to your door.

2. Patient-Controlled Potency

This is the game-changer for Grundy County’s working folks.

Our sublingual oil contains 1,500mg of THCa—the non-psychoactive precursor to THC. You have three choices:

Option 1: Raw (No Heat)
All 1,500mg stays as THCa. Zero psychoactive effects. Perfect for daytime use when you need to work your farm, drive into Waterloo for supplies, or attend your kids’ 4-H events in Conrad. You get anti-inflammatory benefits without impairment.

Option 2: Fully Activated (Home Decarb)
Heat the oil at 260°F for 45-60 minutes. That converts 1,500mg THCa into approximately 1,315mg delta-9 THC. Combined with the existing 90mg delta-9 and 6,000mg delta-8, you now have a full-potency psychoactive product comparable to traditional illegal RSO—100% legally, because you control the activation after purchase.

Option 3: Vape (Instant Decarb)
Our vape cartridge automatically decarboxylates THCa at 400-450°F. Each puff delivers freshly activated cannabinoids with 1-2 minute onset.

One product. Three completely different experiences. You decide, not us.

3. Open-Source Formulas

We don’t hide behind “proprietary blends.” Here’s exactly what’s in our sublingual oil:

That’s 553mg of active cannabinoids per mL. A 30mL bottle gives you 40-60 doses depending on your needs.

If $129.99 doesn’t fit your budget (and we understand—Grundy County’s median household income is around $65,000, and farming has been tough), you can source these cannabinoids yourself. The recipe is right here. That’s the Bentley principle: if you need it, you should have access to it, period.

4. Evidence-Informed, Not Evidence-Overstating

We’re not here to tell you RSO cures cancer. Rick Simpson did that, and we think he went too far. What we are here to do is give you the best possible version of the information so you can make your own informed decision.

Every claim we make is tied to peer-reviewed research. That’s why this guide includes 29 references. When we say CBD has anxiolytic potential, we cite the 2024 meta-analysis[3]. When we discuss delta-9 THC’s pain evidence, we note both the benefits and the risks of dizziness and sedation[13]. When we talk about CBN for sleep, we’re honest that the evidence is weak[16][17].

In Grundy County, where we value straight talk and honest dealing, that matters. You deserve the truth, not hype.

The Evidence: What We Know (And What We Don’t)

The Strongest Evidence: CBD and Delta-9 THC

CBD has the most robust human data:

• Epilepsy: FDA-approved Epidiolex for rare seizure disorders[1][2]
• Anxiety: 2024 meta-analysis showed significant anxiolytic effects in 316 participants[3]
• Pain: Promising but heterogeneous results across studies[4]
• Safety: Can elevate liver enzymes and interact with medications[6]

Delta-9 THC has established but narrow FDA approvals:

• Chemotherapy nausea and HIV/AIDS appetite loss[1]
• Pain relief possible but with significant side effects (dizziness, sedation, nausea)[13]
• High-concentration products linked to psychosis and cannabis use disorder[15]
• Onset in 15-30 minutes when inhaled, 1-2 hours when ingested; duration 2-6 hours[14]

The Emerging Evidence: Minor Cannabinoids

CBG is pharmacologically interesting with potential for neurologic disorders and inflammation, but human trials are sparse[7][8]. We include it because Bentley needed it, and the preclinical data is compelling.

Delta-8 THC is psychoactive and pharmacologically similar to delta-9, but less potent and with less clinical validation[9]-[11]. We use it strategically for its therapeutic profile while maintaining Farm Bill compliance.

THCa shows anti-inflammatory and neuroprotective potential in preclinical studies[12], but human data is limited. We preserve it in its acidic form so you control whether it stays non-psychoactive or converts to THC.

CBN is marketed heavily for sleep, but the evidence is weak—no validated clinical trials using polysomnography[16][17]. We include it at 750mg (25mg per mL) because some users report benefits, but we’re transparent about the science gap.

CBC is one of the most understudied cannabinoids, with promising preclinical work on neurogenesis and inflammation[18][19]. It’s in our formula because Bentley’s dementia taught us that neurogenesis matters.

The Terpene Story: Why Aroma Matters (But Isn’t Magic)

Our products contain 5% live terpenes:

Limonene (citrus-bright): Reviewed for anti-inflammatory and antioxidant properties, but most studies are preclinical[21]. Can cause contact allergies when oxidized[22].

Myrcene: Commonly associated with sedative effects, but human evidence is lacking[23]. It’s in there for entourage potential, not as a proven sleep aid.

Caryophyllene (pepper/spice): The standout—it’s a selective CB2 receptor agonist, giving it cannabinoid-system relevance[24]. This is why we emphasize it for anti-inflammatory support.

Pinene (forest-fresh): Plausible neuroprotective effects in preclinical models[25], but human cognition claims are exploratory.

Linalool (lavender): Associated with stress relief in aromatherapy, with some antidepressant mechanisms studied[26], but clinical cannabis-specific data is limited.

Humulene (earthy/woody): Shows anti-inflammatory promise in rodent studies[27], but human data is minimal.

Terpinolene (piney/fruity): Least studied of our profile, mostly in vitro and animal work[28].

The honest take: Terpenes make the product smell and taste better, and the preclinical data is intriguing. But robust human proof of cannabis-specific entourage effects remains limited[20][29]. We include them because Bentley taught us that plant complexity matters, but we won’t overstate what the science shows.

Condition-Specific Guidance for Grundy County Residents

Critical Disclaimer: These are informed by research, not medical prescriptions. Consult your healthcare provider—especially if you’re receiving treatment at Grundy County Memorial Hospital or seeing specialists in Waterloo. Do not replace proven medical care with RSO. Do not operate vehicles or machinery while using psychoactive cannabinoids.

Chemotherapy Support

If you’re making the drive from Grundy County to oncology centers in Waterloo, Cedar Rapids, or Iowa City:

• Pre-chemo: 0.5-1.0mL sublingual 1 hour before treatment (delivers delta-8 and delta-9 for nausea prevention[9][13])
• Breakthrough nausea: 2-3 vape puffs (1-2 minute onset)
• Post-chemo: 0.5mL every 6 hours as needed
• Sleep during treatment: 1.0-2.0mL before bed (25-50mg CBN)

Chronic Pain (Farm Work, Arthritis, Neuropathy)

We know the physical toll of agriculture in Iowa:

• Daytime: 0.3-0.5mL raw sublingual (non-psychoactive anti-inflammatory via CBD[4], CBG[8], THCa[12], caryophyllene[24])
• Nighttime: 0.5-1.0mL decarbed sublingual (full cannabinoid profile + CBN for sleep[16][17])
• Breakthrough pain: Vape as needed for rapid relief

Sleep Issues

Common in our rural communities, where stress and isolation run deep:

• Before bed: 1.0-2.0mL sublingual
• At 2.0mL, you get 50mg CBN—the dosage level actually studied in 2024 sleep literature[17]
• Even at 1.0mL (25mg CBN), you’re above the 20mg threshold associated with reduced sleep disturbance[16]

Anxiety and PTSD

For veterans in Grundy County, for farmers facing uncertainty, for anyone struggling:

• Daytime functional relief: 0.3mL raw sublingual (CBD[3] and CBG[8] without impairment)
• Nighttime: 1.0mL sublingual (full profile including CBN)

General Titration Principle

Start low, go slow. Begin with 0.25-0.5mL and assess effects over 2-3 hours before increasing. Body weight, metabolism, and concurrent medications (especially if you’re on prescriptions from Grundy County providers) all affect response.

When to Use Which Format

Legal Status: The Iowa Reality

Here’s what Grundy County residents need to know:

Federal Law: The 2018 Farm Bill legalized hemp-derived products containing less than 0.3% delta-9 THC. Our sublingual oil contains only 90mg delta-9 THC total in a 30mL bottle—well under that threshold.

Iowa Law: Iowa’s Hemp Act aligns with federal law, but the state has been aggressive about enforcing delta-8 bans. As of our last update, delta-8 exists in a legal gray area in Iowa. However, our product’s delta-8 content is disclosed and compliant with the Farm Bill at point of sale. Customers in Grundy County should be aware that Iowa law enforcement has taken a hard line on psychoactive hemp products.

Your Responsibility: You must verify current Iowa and Grundy County regulations before ordering. We provide full documentation, Certificates of Analysis, and receipts with every shipment. International customers (if you’re ordering from Canada or elsewhere) accept all customs and legal risk.

Drug Testing: If you’re subject to workplace drug testing (common in Grundy County’s manufacturing and agricultural sectors), be aware:

• Raw THCa will not trigger a standard THC test
• Decarbed THCa and delta-8 THC will trigger tests
• Vape will trigger tests

Be honest with your employer. We are.

The Evidence Connection: Why This Matters for Your Decision

Every cannabinoid and terpene in our formula is linked to specific peer-reviewed citations in this guide. We don’t hide behind proprietary secrets. We show our work.

When we say our sublingual oil delivers 553mg/mL, that’s verifiable by any third-party lab. When we say it contains 1,500mg THCa, that’s measured by HPLC/UHPLC with ±2% accuracy. When we say it’s solvent-free, we provide residual solvent tests showing compliance with FDA Class 3 limits (<5,000 ppm).

This matters in Grundy County because you can’t afford to guess. When you’re dealing with health issues—whether it’s supporting a family member through cancer treatment at the Cedar Rapids oncology center, managing chronic pain from decades of physical labor, or trying to sleep through the night without pharmaceutical side effects—you need products you can trust.

Final Thoughts: Why We’re Telling Grundy County All This

We could have written a simple product page. We could have said “Buy our RSO, it’s the best” and left it at that. But that’s not who we are.

OilWell Cannabis was born from desperation—a man trying to save his dog when veterinarians gave up. It grew from personal suffering—Colin quitting Xanax cold turkey with cannabinoids he formulated himself. It evolved through community—giving away $35,000 in product to help Houston get vaccinated, warning competitors when the law changed overnight, standing up and saying “I have a conviction too” when the President announced pardures.

We’re bringing that same honesty to Grundy County.

If you’re in Grundy Center reading this, or in Dike, or farming outside Holland—you deserve the same level of transparency. You deserve to know exactly what you’re putting in your body, what the evidence says, what the risks are, and how to use it responsibly.

Rick Simpson’s legacy isn’t about a perfect product. It’s about a principle: when the system fails you, you find another way. But that way has to be grounded in reality, not fantasy. It has to respect science while acknowledging its limits. It has to put control in your hands, not ours.

That’s what we’ve built. That’s what we offer to Grundy County.
