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

If you’re in Marshall County—whether you’re tending crops outside Marshalltown, working a shift at the Lennox plant, or caring for family in State Center—you’ve probably heard whispers about Rick Simpson Oil. Maybe a neighbor mentioned it at the Co-op. Maybe you saw a forum post from someone in Des Moines looking for “RSO near Marshall County” who got no clear answers. Maybe you’re a veteran at the Iowa Veterans Home, or a farmer whose back hasn’t been the same since harvest season, and you’re searching for something that actually works when the pills from the VA or the clinic just… don’t.

We’ve been where you are. Not in Marshall County specifically—we’re Houston-based, born from the Texas borderlands where survival meant figuring out what works and what doesn’t. But we built OilWell Cannabis for people exactly like you: practical, hardworking Iowans who deserve honest answers about cannabis medicine, not hype. And we ship directly to Marshall County, legally, under the Farm Bill, with the same products we’ve been refining since 2019.

This guide is for you. Not a watered-down version. Not marketing fluff. Every fact, every number, every study citation you need to make an informed decision—right here, right now.

Who Was Rick Simpson, and What Does RSO Actually Mean?

Rick Simpson wasn’t a doctor. He wasn’t a scientist. He was a power engineer from Nova Scotia who got hurt on the job in 1997—fell from scaffolding, suffered a head injury, and ended up with tinnitus and dizziness that his doctors couldn’t fix. The medications they gave him either didn’t work or made things worse. When he asked his doctor about cannabis, the doctor refused to discuss it. So Simpson figured it out himself.

In 2003, he claimed that three bumps on his arm—diagnosed as basal cell carcinoma—disappeared after he applied concentrated cannabis oil and covered them with bandages for four days. No biopsy confirmation. No clinical documentation. Just his personal testimony. But that testimony became Run From The Cure, the 2005 documentary that introduced millions to the term “Rick Simpson Oil.” He started giving the oil away for free to cancer patients, chronic pain sufferers, diabetics, people with glaucoma, arthritis, depression, insomnia—anyone who asked. He believed the oil could cure cancer. He believed pharmaceutical companies were suppressing it. He believed patients needed 60 grams of oil over 90 days to treat cancer seriously—a protocol that delivers 600-900 mg of THC per day, far beyond anything studied in clinical trials.

Here’s what Simpson got right: He put concentrated cannabis oil on the map when nobody else was talking about it. He created a movement. He gave people hope when conventional medicine ran out of options.

Here’s what Simpson got wrong: He claimed RSO could cure cancer. He encouraged patients to use it instead of proven treatments. He worked without lab testing, without standardization, without any safety protocols. The doses he recommended—600-900 mg of THC daily—carry real risks: severe intoxication, anxiety, panic, tachycardia, dependency, cannabis use disorder. No controlled trial has ever validated his 60-gram protocol. None.

The institutional reality: The National Cancer Institute acknowledges preclinical research showing cannabinoids can induce apoptosis and inhibit tumor growth in cell lines and animals, but explicitly states that cannabis has not been proven to cure cancer in humans. The FDA has approved only purified CBD (Epidiolex) for seizures and synthetic THC analogues for chemo nausea and HIV/AIDS appetite—not the cannabis plant itself. Texas DSHS and Iowa’s medical cannabis program follow the same evidence standard.

So why are we telling you this? Because you deserve the full truth—not the mythologized version. Understanding what RSO was helps you understand what it can be now.

From Simpson’s Kitchen to Our Lab: How We Built Something Better

OilWell Cannabis didn’t start in a boardroom. It started with a border collie named Bentley.

Colin Valencia, our founder, grew up in McAllen, Texas—right across the Rio Grande from Reynosa, one of the most dangerous cities in Mexico. He learned early what it means to hustle in a place where opportunities are scarce and violence is common. He lost friends to prison and death. By sixteen, he was gone—determined to build something honest.

Years later, Bentley got sick. Paralyzed. The vets said euthanasia was the only humane option. 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 changed everything.

Colin made a CBD golden paste for Bentley. Turmeric, coconut oil, black pepper, CBD oil. Bentley got up. Walked over. Brought his ball. Lived ten more years, dying naturally at twenty. Dogs don’t respond to placebo. That was our first clinical trial—one patient, one life, everything on the line.

During those ten years, Bentley aged. Colin developed formulas for neurodegeneration (CBG for neuroprotection, THCa for PPARγ activation), dementia (CBC for neurogenesis), glaucoma (THC for CB1 agonism), and crippling arthritis (multi-pathway anti-inflammatory using CBD, CBG, THCa, and caryophyllene). He learned that single cannabinoids weren’t enough. Precision mattered—Bentley’s life depended on it.

Colin also knows pharmaceutical dependence personally. He fought PTSD and Xanax addiction. He quit benzos cold turkey using the same cannabinoid knowledge that saved Bentley. Our Peace Gummies—the formula that helps people taper off benzodiazepines—was born during midnight experiments while he was in withdrawal. He still uses the vape form for his insomnia and severe PTSD.

This is why we publish our complete formulas. The recipe that saved Bentley? Free on our website. The RSO formula you’re reading about now? Every milligram is published below. If you can’t afford our product, source the ingredients and make it yourself. That’s not marketing—that’s our promise to you.

Why Marshall County Residents Are Searching for RSO

Let’s be direct about what we know life is like here. Marshall County is 573 square miles of rolling farmland, small towns, and tight-knit communities. The agricultural economy means chronic pain—from decades of physical labor, equipment accidents, repetitive stress. The manufacturing sector (Lennox, Emerson, JBS) means workplace injuries, shift work that wrecks sleep, and the constant worry about drug testing. The veteran population here is significant—many served overseas and came back with PTSD, anxiety, and a medicine cabinet full of pills that don’t work or create new problems.

You’ve probably heard about Iowa’s medical cannabis program. Here’s the reality: It’s one of the most restrictive in the country. You need a qualifying condition (cancer, PTSD, seizures, ALS, Parkinson’s, MS, intractable pain). You need a doctor’s certification. The product is limited to 4.5 grams of THC per 90 days. And you can only buy from five state-licensed dispensaries—none in Marshall County. The nearest one is in Windsor Heights, two hours away.

That’s why people in Marshall County search “RSO near me” and get frustrated. That’s why forums have posts from folks in Albion, Le Grand, and Gilman asking where to buy real RSO without driving to Des Moines or ordering from sketchy sources.

We built OilWell for exactly this situation.

The Legal Framework: Why We Can Ship to Marshall County

The 2018 Farm Bill legalized hemp and hemp-derived products containing less than 0.3% delta-9 THC by dry weight at the federal level. This is the foundation of everything we do.

Our RSO Sublingual Oil contains only 90 mg of delta-9 THC in the entire 30 mL bottle—3 mg per mL. That’s well under the 0.3% threshold. All cannabinoids are hemp-derived. This product is legal in Iowa and ships directly to your door.

Here’s where it gets powerful: We include 1,500 mg of THCa—the acidic, non-psychoactive precursor to THC. THCa is not delta-9 THC, so it’s Farm Bill compliant at the point of sale. But when you heat it at home (260°F for 45-60 minutes), it converts to approximately 1,315 mg of delta-9 THC. Combined with the existing 90 mg, you get ~1,405 mg of total delta-9 THC—psychoactive potency comparable to traditional illegal RSO, 100% legally, because you control the activation.

This means one product serves three needs:

1. Raw (no heat): Non-psychoactive anti-inflammatory for daytime use. Work in the fields, drive into Marshalltown, attend church—zero impairment.
2. Decarboxylated (home activation): Full-potency psychoactive medicine for nighttime or serious conditions.
3. Vaped (instant activation): Fast relief for breakthrough pain, panic, or nausea—onset in 1-2 minutes.

Important legal notice: Iowa law prohibits possession of marijuana, but hemp-derived products with <0.3% delta-9 THC are legal. When you decarboxylate THCa at home, you become responsible for the resulting THC content. We provide complete documentation, COAs, and receipts for every order. International customers accept all customs and legal risk.

What Makes Our RSO Different: The Formula That Speaks for Itself

We don’t hide behind “proprietary blends.” Here is exactly what’s in our RSO Sublingual Oil—the same formula we use, the same formula you can make at home if you choose.

Active per mL: 553 mg
Format: 30 mL bottle with graduated dropper (0.1 mL increments)
Base: Organic MCT oil
Terpenes: Live terpenes at 5% (limonene, myrcene, caryophyllene, pinene, linalool, humulene, terpinolene)
Onset: 15-45 minutes sublingually
Duration: 4-6 hours
Bioavailability: 13-19%
Doses per bottle: 40-60 depending on serving size

Compare this to Simpson’s traditional RSO:

• Simpson’s oil: Unknown potency, unknown cannabinoid ratios, no terpenes, residual solvent risk, illegal to ship.
• Our oil: 16,590 mg of precisely measured cannabinoids across 7 compounds, live terpenes, solvent-free, third-party tested, Farm Bill compliant, ships directly to Marshall County.

The RSO Vape Cartridge offers the same profile in a 1-gram format with 900+ mg total cannabinoids, 5%+ terpenes, and instant onset (1-2 minutes) for breakthrough symptoms.

Why 7 cannabinoids? Because Bentley taught us that single molecules fail complex conditions. A farmer with arthritis and PTSD needs multi-pathway support. A veteran with chronic pain and insomnia needs more than just THC. Our formula addresses inflammation (CBD, CBG, THCa, caryophyllene), pain (delta-8, delta-9, CBC), anxiety (CBD, CBG, limonene), and sleep (CBN, myrcene, linalool) simultaneously.

When to Use Each Format: Practical Guidance for Marshall County Life

Evidence That Matters: What Science Actually Says

We don’t cherry-pick studies. Here’s the evidence hierarchy for every compound:

Strongest Human Evidence:

• CBD: Proven for rare epilepsies (Epidiolex). Promising for anxiety and pain, but literature remains limited [1][2][3][4].
• Delta-9 THC: Proven for chemo nausea and HIV appetite. Short-term pain benefit possible, but adverse effects (dizziness, sedation, dependency) are real [1][13][14][15].

Emerging/Preclinical:

• CBG: Selective CB2 agonist, neuroprotective potential, but human trials are sparse [7][8].
• Delta-8 THC: Similar to delta-9 but less potent; real psychoactivity but incomplete safety data [9][10][11].
• CBN: Marketed for sleep, but clinical evidence is weak—no validated trials support strong sleep claims [16][17].

Early Stage:

• CBC: Distinct pharmacology, antinociceptive and neurogenic potential, but clinical validation lacking [18][19].
• THCa: Anti-inflammatory via COX-2, neuroprotective via PPARγ, but interpretation depends on decarboxylation [12].

Terpenes: Beta-caryophyllene is a CB2 agonist. Limonene and linalool have preclinical anti-anxiety signals. But robust human proof of entourage effects is limited [20][24][25][26].

Bottom line: Our formula combines the best-supported actives (CBD, delta-9 THC) with promising minors (CBG, CBC) and terpenes for potential synergy. We don’t overstate—we provide the best version so you can judge for yourself.

Safety: What Marshall County Needs to Know

Every product includes these warnings:

• Age 21+ only
• Do not operate vehicles or machinery while impaired
• Consult healthcare provider before use, especially if pregnant, nursing, taking medications, or have medical conditions
• May cause drowsiness
• Keep out of reach of children

Drug testing: Delta-8 THC, delta-9 THC, and decarboxylated THCa will trigger positive results on standard cannabis drug tests. Raw THCa will not. If you work at Lennox, JBS, or any manufacturing facility in Marshall County that tests, use the raw sublingual option for daytime, or plan accordingly.

Interactions: CBD can affect liver enzymes and interact with medications like blood thinners, anticonvulsants, and some antidepressants. Always consult your doctor.

Storage: Store in a cool, dark place. THCa can slowly decarboxylate over time if exposed to heat or light. For Marshall County winters, avoid leaving in vehicles overnight.

Cost and Accessibility: The Open-Source Promise

Our RSO Sublingual Oil is $129.99 for 16,590 mg of cannabinoids. That’s $7.83 per gram of total cannabinoids—far less than you’d pay at a medical dispensary in Des Moines for a single cannabinoid product.

But we know $129.99 is real money. If you can’t afford it, make it yourself. The complete formula is published above. Source:

• CBD distillate: 4,500 mg
• CBG isolate: 3,000 mg
• Delta-8 distillate: 6,000 mg
• THCa isolate: 1,500 mg
• Delta-9 distillate: 90 mg
• CBN isolate: 750 mg
• CBC isolate: 750 mg
• Live terpene blend: 1,500 mg (5% of 30 mL)
• Organic MCT oil: q.s. to 30 mL

Mix at low heat (<140°F), bottle, label. You now have the same product we sell.

This is our answer to Simpson’s free-distribution model. We can’t give it away (we have labs to pay, employees to support), but we can give away the knowledge. That’s the OilWell promise.

Resources for Marshall County Residents

Medical consultation: If you’re under care at Marshalltown Medical & Surgical Center or have a primary care provider, discuss cannabinoid use with them. Bring our COA and formula sheet—they’ll see exactly what you’re taking.

Veteran support: Connect with the Iowa Veterans Home in Marshalltown (641-753-4101) or the Marshall County Veterans Affairs office (641-754-6380) for benefits counseling. Our products are not VA-approved, but many veterans use them alongside VA care.

Addiction recovery: For those tapering benzos or opioids, contact the Iowa Department of Public Health’s Prevention Services (1-866-227-9887) for support. Our Peace Gummies formula was designed for this, but professional medical supervision is critical.

Cancer support: The Holden Comprehensive Cancer Center in Iowa City (319-356-4200) and the MercyOne Cancer Center in Des Moines (515-643-8200) offer integrative oncology consultations. RSO is not a substitute for proven treatment, but may complement supportive care.
