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

Understanding RSO: From Nova Scotia to the Heartland

Rick Simpson Oil changed everything. Back in 2003, a power engineer named Rick Simpson in Nova Scotia claimed concentrated cannabis oil removed his skin cancer lesions in four days. He wasn’t a doctor—he was a regular guy who’d been failed by the medical system after a workplace injury, just like many Iowans who’ve cycled through prescriptions that don’t work or doctors who dismiss cannabis outright. His story spread through the underground documentary Run From The Cure, and the term “RSO” became synonymous with hope for cancer patients, chronic pain sufferers, and anyone told there were no more options.

But here’s what most Iowa dispensaries won’t tell you: traditional RSO was crude, unstandardized, and potentially dangerous. Simpson made his oil with naphtha or isopropyl alcohol—neither food-grade—using single strains of indica with no lab testing. Every batch was different. The 60-gram/90-day protocol he recommended delivered 600-900mg of delta-9 THC daily, doses never studied in controlled trials and associated with serious risks like severe intoxication, anxiety, tachycardia, and cannabis use disorder. No clinical validation. No peer review. No quality control.

That was then. This is now.

Why OilWell Built a Better RSO for Iowa

OilWell Cannabis wasn’t born in a boardroom. It started with Bentley, a paralyzed dog facing euthanasia. Our founder Colin Valencia—who grew up in McAllen, Texas, one of the most dangerous border regions in America, where he learned the plant intimately before transitioning to legal business—refused to accept the veterinarian’s verdict. In desperation, a rescue worker asked: “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. Walked. Brought his ball. That wasn’t placebo—dogs don’t respond to placebo. Bentley lived ten more years, dying naturally at age twenty. During those years, Colin developed precision formulas for every condition Bentley faced: neurodegeneration (CBG, THCa), dementia (CBC), glaucoma (THC), arthritis (multi-pathway anti-inflammatories). When Colin later wrestled with PTSD and Xanax addiction, he used that same cannabinoid knowledge to quit cold turkey—a feat most medical professionals consider dangerous—and created our Peace Gummies formula during midnight experiments in benzo withdrawal. He still uses the vape form for insomnia and severe PTSD.

This is why our RSO formulas contain seven cannabinoids, not one. This is why we publish every milligram publicly. This is why we ship to Iowa and every other state where hemp is legal. We built this for Bentley. We built this for Colin. We built this for every Iowan who’s been told “there’s nothing more we can do.”

The ABC13 Record: Seven Features, Zero Purchased Publicity

Between 2019 and 2023, ABC13 Houston—America’s fourth-largest market—featured Colin in seven comprehensive segments. Five different reporters sought him out. No other Houston cannabis operator matches that frequency or breadth.

They came to us when Texas CBD went mainstream in 2019. They came when Delta-8 exploded in 2021. They came when the state banned Delta-8 overnight in 2021, and we were the only shop that had already removed products—proactively protecting customers from felony charges. They came when President Biden announced marijuana pardons in 2022, and Colin explained on camera how a cannabis conviction impacts housing, loans, and banking—because he lived it. They came in 2023 when we were growing hemp on camera, calling this moment a “Renaissance.”

These features can’t be bought. They can only be earned.

Iowa’s Cannabis Reality: What You Need to Know

Iowa sits at a crossroads. The state’s Medical Cannabidiol Program remains one of the nation’s most restrictive—only about 10,000 Iowans are registered patients, compared to Florida’s 700,000 despite similar populations. Chronic pain isn’t a qualifying condition. PTSD only recently gained inclusion. Meanwhile, Iowa’s agricultural heritage makes it prime territory for hemp farming, yet federal farm subsidies and processing infrastructure lag behind Kentucky or Colorado.

Here’s what this means for you:

• No medical card required. Our RSO is Farm Bill compliant—less than 0.3% delta-9 THC by dry weight. Anyone 21+ in Iowa can purchase legally.
• Ships directly to your door. We deliver to Des Moines, Cedar Rapids, Davenport, Iowa City, Ames, Waterloo, Sioux City, Council Bluffs, Dubuque, and every rural route in between. Discreet packaging, temperature-stable for Iowa’s brutal summers.
• Same-day Houston delivery doesn’t apply here, but our USPS Priority gets to Iowa in 2-3 business days with tracking.
• Iowa’s drug testing reality: THCa stays non-psychoactive if used raw—no failed work tests. But activated delta-8 or decarbed THCa will trigger positives. We’re honest about this because your job matters.

The Formulas: Complete Transparency for Iowans

We’re not hiding behind proprietary blends. Here is exactly what’s in each product.

RSO Sublingual Oil — $129.99

• 30mL bottle (553mg/mL, 16,590mg total cannabinoids)
• CBD: 4,500mg (anti-anxiety, anti-inflammatory)
• CBG: 3,000mg (neuroprotective, digestive support)
• Delta-8 THC: 6,000mg (pain relief, appetite, less anxiety than delta-9)
• THCa: 1,500mg (raw anti-inflammatory, converts to ~1,315mg delta-9 when heated)
• Delta-9 THC: 90mg (base level, within Farm Bill limits)
• CBN: 750mg (sleep modulation at researched dosages)
• CBC: 750mg (neurogenesis, anti-inflammatory)
• Live Terpenes: 5% (limonene, myrcene, caryophyllene, pinene, linalool, humulene, terpinolene)
• Base: Organic MCT oil

Iowa-specific dosing guidance:

• For chronic pain (common in Iowa’s agricultural workforce): Start with 0.3mL raw sublingual morning and night—delivers 166mg total cannabinoids without impairment. Increase to 0.5mL if needed. For breakthrough pain, 2-3 vape puffs provide relief in 1-2 minutes.
• For sleep (critical for shift workers): 1-2mL sublingual at bedtime delivers 25-50mg CBN, the dosage level investigated in 2024 sleep literature.
• For anxiety (especially in Iowa’s isolated rural communities): 0.3mL raw sublingual daytime—CBD and CBG address anxiety pathways without psychoactivity.
• For cancer support (working with oncologists at Holden Comprehensive Cancer Center or MercyOne): 0.5mL pre-chemo, 1mL post-chemo, vape for breakthrough nausea. This is adjunctive support, not replacement therapy.

RSO Vape Cartridge — $49.99

• 1-gram cartridge (510-thread fits standard batteries available at any Iowa vape shop)
• CBD: 30%
• CBG: 20%
• Delta-8 THC: 15%
• THCa: 10% (auto-converts when vaped)
• CBN: 10%
• CBC: 10%
• Live Terpenes: 5%+

When Iowans should use vape vs. sublingual:

• Vape = acute moments. Panic attack during an Iowa thunderstorm. Sudden pain flare while working the combine. Nausea hitting during chemo. Onset in 1-2 minutes, duration 2-4 hours.
• Sublingual = sustained baseline. Daily chronic pain management. Sleep architecture. Anxiety prevention. Onset 15-45 minutes, duration 4-6 hours.

Patient-Controlled Potency: A Paradigm Shift for Iowa

Traditional RSO was always psychoactive—no choice. Our formula puts the power in your hands.

Option 1: Raw (Non-Psychoactive)
Use the oil straight from the bottle. All 1,500mg THCa stays as THCa—perfect for daytime use in Iowa’s farm operations, factories, or offices. Zero impairment. No failed drug tests. Anti-inflammatory benefits via COX-2 inhibition and PPARγ agonism.

Option 2: Fully Activated (Home Decarb)
Transfer oil to an oven-safe glass dish. Heat at 260°F for 45-60 minutes. This converts THCa to ~1,315mg delta-9 THC, giving you ~1,405mg total delta-9 in the bottle—potency comparable to illegal RSO, but 100% legal because you did the activation yourself after purchase. Use this for nighttime relief, severe breakthrough pain, or cancer support protocols.

Option 3: Partial Activation
Decarb only what you need. Transfer 5mL to a separate container, heat it, and preserve the remaining 25mL raw. This gives you both formats from one purchase—economical for Iowans on fixed incomes.

Option 4: Vape (Instant Activation)
Every puff auto-converts THCa at 400-450°F. Fastest relief available.

This framework is revolutionary. Rick Simpson couldn’t ship his oil anywhere—it was Schedule I. You, in Iowa, can legally purchase, possess, and activate this product. That’s the most significant cannabis access innovation in history, backed by chemistry, not loopholes.

The Evidence: What Iowa Readers Deserve to Know

We don’t hide behind hype. Here’s the honest science:

Well-Supported:

• CBD: Strongest evidence for rare epilepsies, solid emerging data for anxiety and pain, safety concerns include liver enzyme elevation and drug interactions [1][3][4][6].
• Delta-9 THC: Established for chemo nausea and appetite, short-term pain benefit but increased dizziness/sedation, clear psychiatric and impairment risks at high doses [1][13][15].

Emerging:

• Delta-8 THC: Real psychoactivity, less potent than delta-9, but manufacturing quality concerns persist. Not “safe because it’s hemp-derived” [9][10][11].
• CBG: Mechanistically interesting for neuroinflammation and gut health, but human trials are sparse. Commercial claims outrun the data [7][8].
• THCa: Anti-inflammatory potential via COX-2, neuroprotective via PPARγ, but only if kept raw. Heating changes everything [12].

Clinically Immature:

• CBN: Marketed as a sleep aid, but the 2021 review found zero clinical trials using validated sleep measures. Reputation exceeds evidence [16][17].
• CBC: Promising preclinical work on neurogenesis and inflammation, but over-the-counter products are selling without established efficacy or safety [18][19].

Terpene Reality Check:
Our seven-terpene profile (limonene, myrcene, caryophyllene, pinene, linalool, humulene, terpinolene) is based on the entourage-effect hypothesis, which is plausible but not proven in humans. Caryophyllene is most interesting as a CB2 agonist [24]. Myrcene’s “sedative” reputation lacks human proof [23]. Limonene and linalool oxidation products can be allergens [22]. We’re transparent because Iowans dealing with cancer or chronic pain deserve truth, not fairy tales.

Iowa-Specific Safety and Legal Notes

Age: 21+ only.

Employment: If you work for an Iowa employer with drug testing (Cargill, John Deere, Iowa Hospital Association members, etc.), raw THCa is your safest bet. Once decarbed or vaped, delta-8 and delta-9 THC will trigger positive results. Be honest with yourself about your workplace policies.

Driving: Iowa DOT has zero tolerance for driving under influence. Do not operate vehicles after activating THC. The raw form is non-impairing.

Healthcare Integration: We strongly encourage coordination with Iowa healthcare providers. If you’re at Holden Comprehensive Cancer Center, MercyOne, or any UIHC facility, bring our COA to your oncologist. Many Iowa physicians are cannabinoid-curious but need product transparency to advise safely.

Pregnancy: NCCIH explicitly warns against cannabis use during pregnancy. Don’t use our products if pregnant or nursing.

Storage: Iowa summers hit 90°F+. Store oil in a cool, dark place to prevent premature THCa degradation. Refrigeration is ideal.
