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

Why Grundy County Residents Are Turning to RSO

For generations, farmers in Grundy County have relied on practical, no-nonsense solutions to health challenges. When conventional medicine falls short—whether it’s arthritis from years of fieldwork, chronic pain from old injuries, or the sleepless nights that come with stress—many in our community start looking for alternatives that align with our values of self-reliance and natural healing.

That’s where Rick Simpson Oil (RSO) comes in. This concentrated cannabis extract has become a topic of conversation across Grundy County, from the cafes in Grundy Center to the farm supply stores in Reinbeck. But what exactly is RSO? How does it differ from the CBD products already available in Iowa? And most importantly—how can Grundy County residents access a version that’s safe, legal, and backed by real science?

At OilWell Cannabis, we’ve spent years perfecting RSO formulas that honor Rick Simpson’s original vision while addressing the very real limitations of traditional production methods. Our products are designed for Iowans who want more than just another wellness trend—they want honest, effective solutions that work with their lifestyle.

The Rick Simpson Story: From Nova Scotia to Grundy County

Rick Simpson wasn’t a doctor or scientist. He was a maintenance worker from Nova Scotia who, after a workplace accident left him with persistent post-concussion symptoms, discovered that cannabis provided relief when pharmaceuticals failed him. His journey took a pivotal turn in 2003 when he claimed that cannabis oil eliminated his skin cancer lesions—a personal testimony that would spark a global movement.

Simpson’s crusade was radical in its simplicity: he made cannabis oil and gave it away for free to anyone who needed it. He helped people with cancer, chronic pain, diabetes, infections, and more—charging nothing, asking for nothing in return. His 2005 documentary Run From The Cure became a cornerstone of cannabis education, introducing millions to the concept of concentrated cannabis oil as medicine.

But here’s what most Grundy County residents don’t know: Simpson’s oil was never standardized, never lab-tested, and carried significant risks. The traditional RSO protocol called for consuming 60 grams of crude, high-THC oil over 90 days—a dose that could deliver 600-900mg of THC daily, far exceeding anything studied in clinical settings. The oil was made with solvents like naphtha, which could leave harmful residues, and every batch was different because there was no quality control.

Simpson’s story matters to Grundy County because it represents the same spirit of self-reliance that defines our community. But his methods also reflect an era when cannabis was illegal and resources were limited. Today, we have the opportunity to build on his legacy with products that are safe, consistent, and grounded in modern science.

The Evolution of RSO: From Traditional to Modern Formulations

When we look at traditional RSO versus modern formulations like OilWell’s, the differences are stark:

For Grundy County residents, these differences matter. The unpredictable nature of traditional RSO made it difficult to use safely, especially for those managing chronic conditions. OilWell’s approach solves these problems while preserving what made RSO special in the first place: its full-spectrum nature and therapeutic potential.

Why OilWell’s RSO Stands Out for Grundy County Residents

1. No Medical Card Required

Unlike Iowa’s medical cannabis program, which requires a qualifying condition and a physician’s recommendation, OilWell’s RSO is available to any adult aged 21 or older. This is particularly important for Grundy County residents who may not have easy access to healthcare providers familiar with cannabis or who don’t qualify under Iowa’s limited medical program.

2. Patient-Controlled Potency

Our RSO contains 1,500mg of THCa—the non-psychoactive precursor to THC. This means you can use it raw for daytime relief without impairment, or decarboxylate it at home to convert the THCa into psychoactive THC when you need stronger effects. This flexibility is ideal for Grundy County farmers, teachers, healthcare workers, and others who need to function during the day but want therapeutic benefits.

3. Solvent-Free Production

Traditional RSO was made with naphtha or isopropyl alcohol, which could leave harmful residues. OilWell uses organic MCT oil as the carrier and third-party lab testing to ensure our products are free from solvents, pesticides, heavy metals, and microbial contaminants. Every batch comes with a Certificate of Analysis (COA), so you know exactly what you’re getting.

4. Multi-Cannabinoid Formula

While traditional RSO was overwhelmingly THC, OilWell’s formula includes seven cannabinoids:

• CBD (4,500mg): The most well-researched cannabinoid for pain, anxiety, and inflammation
• CBG (3,000mg): Emerging research suggests neuroprotective and anti-inflammatory properties
• Delta-8 THC (6,000mg): A milder psychoactive cannabinoid with potential anti-nausea and pain-relieving effects
• THCa (1,500mg): The non-psychoactive precursor to THC with its own therapeutic potential
• Delta-9 THC (90mg): The primary psychoactive cannabinoid, kept at a low dose for safety
• CBN (750mg): Often associated with sleep support
• CBC (750mg): May support neurogenesis and pain relief

This multi-cannabinoid approach aligns with the “entourage effect” theory, which suggests that cannabinoids may work better together than in isolation.

5. Two Product Formats for Different Needs

We offer our RSO in two formats, each designed for different use cases:

RSO Sublingual Oil ($129.99)

• 30mL bottle
• 16,590mg total cannabinoids (553mg per mL)
• Onset: 15-45 minutes
• Duration: 4-6 hours
• Ideal for sustained relief, precise dosing, and daytime use

RSO Vape Cartridge ($49.99)

• 1-gram cartridge
• 900mg+ total cannabinoids
• Onset: 1-2 minutes
• Duration: 2-4 hours
• Ideal for fast relief of acute symptoms like breakthrough pain or nausea

6. Open-Source Formulas

In the spirit of Rick Simpson’s original ethos, we publish our complete formulas so that anyone who can’t afford our products can make their own. This is particularly relevant for Grundy County residents who value self-sufficiency and may want to create their own versions at home.

Here’s our RSO Sublingual Oil formula:

And our terpene profile (included in both products):

• Limonene (citrus-bright)
• Myrcene (relaxing)
• Caryophyllene (peppery, CB2 agonist)
• Pinene (forest-fresh)
• Linalool (floral, lavender)
• Humulene (earthy)
• Terpinolene (piney, fruity)

The Science Behind OilWell’s RSO

At OilWell, we don’t just make claims—we back them up with peer-reviewed research. Here’s what the science says about the key components of our RSO:

CBD: The Most Studied Cannabinoid

• Pain: A 2024 systematic review found that CBD shows promise for pain relief, though more high-quality studies are needed [4].
• Anxiety: A 2024 meta-analysis of 316 participants found a statistically significant anxiolytic effect, but noted that the clinical sample remains limited [3].
• Safety: The same meta-analysis found that CBD is generally well-tolerated, though it can cause diarrhea, sleepiness, and potential liver enzyme elevation in some cases [3].

CBG: The “Stem Cell” Cannabinoid

• CBG is the precursor to many other cannabinoids and has shown promise in preclinical studies for neuroprotection, inflammation, and antibacterial activity [7][8].
• A 2021 review noted that CBG is already being sold commercially despite limited clinical evidence, emphasizing the need for more research [7].

Delta-8 THC: A Milder Alternative

• Delta-8 THC is chemically similar to delta-9 THC but appears to be less potent [9].
• A 2022 review found that delta-8 THC has broadly similar pharmacokinetics to delta-9 THC but with weaker CB1 affinity [9].
• Public health literature has raised concerns about manufacturing quality and potential contaminants in some delta-8 products [10].

THCa: The Non-Psychoactive Precursor

• THCa is the acidic form of THC and does not produce psychoactive effects unless decarboxylated (heated) [12].
• Preclinical research suggests potential anti-inflammatory and neuroprotective properties [12].

CBN: The Sleep Cannabinoid?

• Despite its reputation as a sleep aid, a 2021 review found no strong clinical evidence supporting CBN’s use for sleep [16].
• A 2024 review on cannabis and sleep concluded that more research is needed to understand cannabinoids’ effects on sleep architecture [17].

Terpenes: More Than Just Aroma

• Terpenes are aromatic compounds that may contribute to the entourage effect—the theory that cannabinoids and terpenes work better together [20][29].
• While preclinical research is promising, human studies are limited. For example:
  • Caryophyllene is a CB2 agonist, meaning it may have anti-inflammatory properties [24].
  • Limonene has shown antioxidant and anti-inflammatory effects in preclinical studies [21].
  • Myrcene is often associated with sedative effects, but human evidence is lacking [23].

How Grundy County Residents Are Using RSO

Chronic Pain Management

Grundy County has a higher-than-average population of farmers, construction workers, and tradespeople—occupations that often come with chronic pain from years of physical labor. Many have found that RSO offers a natural alternative to opioids or over-the-counter pain relievers.

Typical dosing for chronic pain:

• Daytime: 0.3-0.5mL raw sublingual oil (provides anti-inflammatory benefits without psychoactive effects)
• Nighttime: 0.5-1.0mL decarboxylated sublingual oil (combines pain relief with CBN for sleep support)
• Breakthrough pain: Vape as needed for rapid onset

Evidence context:

• CBD has shown promise for pain relief in systematic reviews [4].
• Delta-9 THC may provide short-term pain benefit but also increases side effects like dizziness and sedation [13].
• Beta-caryophyllene, one of our terpenes, is a CB2 agonist that may contribute to anti-inflammatory effects [24].

Sleep Support

Insomnia is a common issue in Grundy County, whether due to stress, chronic pain, or the irregular schedules that come with farming. Many residents have found that RSO helps them achieve more restful sleep.

Typical dosing for sleep:

• 1.0-2.0mL sublingual oil before bed
• At 2.0mL, this delivers 50mg CBN—the dosage level investigated in recent sleep literature [16][17].

Evidence context:

• While CBN is often marketed as a sleep aid, the clinical evidence is weak [16].
• The overall cannabis and sleep literature is still developing, with many studies relying on subjective measures [17].

Anxiety and Stress Relief

From the pressures of farming to the challenges of small-town life, anxiety affects many in Grundy County. RSO offers a natural option for those looking to manage stress without the side effects of pharmaceuticals.

Typical dosing for anxiety:

• Daytime: 0.3mL raw sublingual oil (CBD and CBG provide anxiolytic benefits without impairment)
• Nighttime: 1.0mL sublingual oil (full cannabinoid profile including CBN for sleep architecture)

Evidence context:

• CBD has shown anxiolytic effects in systematic reviews [3].
• CBG’s pharmacology suggests potential relevance for anxiety, though human studies are limited [7][8].

Chemotherapy Support

For Grundy County residents undergoing chemotherapy at UnityPoint Health – Grundy County Memorial Hospital or other nearby facilities, RSO may help manage nausea and improve appetite.

Typical dosing for chemo support:

• Pre-chemo: 0.5-1.0mL sublingual oil approximately 1 hour before treatment
• Acute breakthrough nausea: 2-3 vape puffs for immediate relief
• Post-chemo: 0.5mL sublingual every 6 hours as needed

Evidence context:

• Delta-8 THC has shown antiemetic effects in preclinical studies [9].
• Delta-9 THC is well-documented for chemotherapy-induced nausea and vomiting [1][13].

Safety and Legal Considerations for Grundy County

Is RSO Legal in Iowa?

Yes. OilWell’s RSO is legal under federal law because it contains less than 0.3% delta-9 THC by dry weight. The 2018 Farm Bill legalized hemp and hemp-derived products at the federal level, and Iowa has aligned its state laws with this standard.

Our product contains 90mg of delta-9 THC in the entire 30mL bottle—just 3mg per mL, well under the 0.3% threshold. The 1,500mg of THCa is not counted as delta-9 THC at the point of sale, though it can be converted to THC through decarboxylation (heating) at home.

Important legal notice: THCa converts to delta-9 THC when heated. Customers are responsible for understanding and complying with their local laws regarding cannabinoid products. OilWell ships with full documentation, Certificates of Analysis, and receipts. International customers accept all customs and legal responsibility.

Safety Considerations

• Start low, go slow: Begin with 0.25-0.5mL and assess effects over 2-3 hours before increasing.
• Drug interactions: Cannabinoids can interact with medications, particularly those metabolized by the liver. Consult your healthcare provider if you’re taking prescription medications.
• Impairment: Delta-9 THC and delta-8 THC can cause impairment. Do not operate vehicles or machinery while under their influence.
• Pregnancy and nursing: Avoid cannabinoid products during pregnancy and while breastfeeding.
• Age requirement: Our products are for adults aged 21 and older.

Will RSO Show Up on a Drug Test?

Possibly. Most standard drug tests screen for THC metabolites. If you use the RSO in its raw form (without decarboxylating the THCa), you’re less likely to test positive. However, if you decarboxylate the oil or use the vape cartridge, delta-9 THC and delta-8 THC will be present and could trigger a positive result.

Why Grundy County Trusts OilWell

A Company Built on Real Experiences

OilWell wasn’t founded in a boardroom—it was built from real experiences that many in Grundy County can relate to:

• Bentley’s Story: Our founder, Colin Valencia, saved his paralyzed dog Bentley from euthanasia using a homemade CBD formula. Over the next ten years, Colin developed specialized cannabis formulas for every condition Bentley faced—neurodegeneration, dementia, glaucoma, and arthritis. This hands-on experience taught him that single cannabinoids weren’t enough; real relief required multi-cannabinoid synergy.

• Colin’s Journey: Colin also knows pharmaceutical dependence firsthand. He used the same cannabinoid knowledge he developed for Bentley to quit Xanax cold turkey. The Peace Gummies formula, which many Grundy County residents use for sleep and anxiety, was born from his own midnight experiments during benzo withdrawal.

Media Recognition

OilWell has been featured in seven news segments on ABC13 Houston, one of the most trusted news sources in the country. These features span business, law, medicine, and community health—demonstrating our expertise and commitment to responsible cannabis education.

Community Commitment

We believe in giving back. In 2021, we gave away $35,000 worth of cannabis products to encourage COVID-19 vaccination in Houston. When Delta-8 THC was suddenly classified as a Schedule I substance in Texas, we proactively removed all Delta-8 products from our shelves before enforcement began and warned other operators who were unknowingly shipping illegal products.

Transparency

We publish our complete formulas so that anyone who can’t afford our products can make their own. This open-source approach aligns with the values of self-reliance that many in Grundy County share.

Frequently Asked Questions

Q: How is OilWell’s RSO different from the RSO I can buy at a local CBD store in Iowa?
A: Many products labeled as RSO are actually just high-THC cannabis oil with no standardization or testing. OilWell’s RSO is a formulated product with seven specific cannabinoids at precise ratios, live terpenes, and third-party lab testing. We also offer two formats (sublingual oil and vape cartridge) and patient-controlled potency through THCa.

Q: Can I use RSO for my arthritis pain?
A: Many Grundy County residents with arthritis have found relief using RSO. Our formula includes multiple anti-inflammatory cannabinoids (CBD, CBG, THCa) and the terpene beta-caryophyllene, which is a CB2 agonist. Start with 0.3-0.5mL of the raw sublingual oil for daytime use and 0.5-1.0mL of decarboxylated oil at night.

Q: I work in agriculture and need to pass drug tests. Can I use RSO?
A: If you use the RSO in its raw form (without decarboxylating the THCa), you’re less likely to test positive for THC. However, there’s still a small amount of delta-9 THC in the product (90mg total in the bottle). For complete safety, consider using a CBD-only product or consult with your employer about their drug testing policies.

Q: How do I decarboxylate the oil at home?
A: To convert THCa to delta-9 THC:

1. Preheat your oven to 260°F (125°C).
2. Place the desired amount of oil in an oven-safe glass container.
3. Heat for 45-60 minutes.
4. Allow to cool before use.

Q: Is RSO safe for older adults in Grundy County?
A: Many older adults in Grundy County use RSO for conditions like arthritis, insomnia, and chronic pain. However, cannabinoids can interact with medications, particularly blood thinners and sedatives. Always consult with your healthcare provider before starting any new supplement, especially if you’re taking prescription medications.

Q: Can I use RSO for my dog?
A: While we don’t recommend giving our RSO products to pets (they contain THC, which can be harmful to animals), we do publish the CBD golden paste recipe that saved Bentley’s life. This recipe is safe for pets and has helped many Grundy County residents manage their animals’ pain, anxiety, and age-related conditions.
