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

A New Era of Cannabis Access in Central Iowa

For residents of Marshall County, Iowa—home to Marshalltown, Albion, and the rolling farmlands of the Iowa River Valley—access to high-quality, legal cannabis medicine has never been more important. Whether you’re managing chronic pain, supporting a loved one through cancer treatment, or seeking natural alternatives for anxiety and sleep, the therapeutic potential of cannabis extracts like Rick Simpson Oil (RSO) offers new hope.

At OilWell Cannabis, we believe Marshall County deserves better than the limited options currently available in Iowa’s medical cannabis program. That’s why we’ve developed a revolutionary RSO formula that combines the wisdom of Rick Simpson’s original vision with modern science, rigorous testing, and complete transparency. Our products are legal under federal law, available without a medical card, and shipped directly to your door in Marshall County—whether you’re in Marshalltown, Melbourne, or any of the county’s 40 townships.

Understanding Rick Simpson Oil: From Nova Scotia to Marshall County

Who Was Rick Simpson?

Rick Simpson wasn’t a doctor or scientist. He was a power engineer from Nova Scotia who discovered cannabis oil after conventional medicine failed him following a serious workplace injury. When his physician refused to consider cannabis as a treatment option, Simpson began researching alternative approaches and learned about a 1974 NIH-funded study at the Medical College of Virginia that found THC could slow tumor growth in mice.

In 2003, Simpson claimed that cannabis oil eliminated his basal cell carcinoma lesions within days—a personal testimony that became the foundation of the global RSO movement. While his story lacks clinical documentation, it sparked a revolution in cannabis medicine that continues to resonate with Marshall County residents seeking natural alternatives.

Traditional RSO vs. Modern Formulations

Simpson’s original RSO protocol called for consuming 60 grams of high-THC oil over 90 days. However, his method had significant limitations:

  • Uncontrolled potency: Each batch varied widely in THC content (60-90%)
  • Dangerous solvents: Used naphtha or isopropyl alcohol, risking toxic residues
  • No terpenes: Heat destroyed beneficial aromatic compounds
  • No lab testing: No standardization or safety verification
  • Extreme doses: Delivered 600-900mg THC daily—far above studied levels

At OilWell Cannabis, we’ve evolved Simpson’s vision with a modern, evidence-based approach that addresses these concerns while maintaining the spirit of his advocacy.

OilWell Cannabis: Built on Compassion and Science

From Marshall County’s Challenges to Cannabis Innovation

Our founder, Colin Valencia, understands the struggles many Iowans face. While Marshall County enjoys a strong agricultural heritage and community spirit, residents also contend with:

  • Limited healthcare access: Rural areas often lack specialists and pain management clinics
  • Opioid crisis impact: Iowa has seen rising opioid-related deaths, with Marshall County affected
  • Aging population: Nearly 18% of Marshall County residents are 65+, facing chronic conditions
  • Cancer prevalence: Iowa has some of the nation’s highest cancer rates, with Marshall County no exception

Colin’s journey began not in a lab, but in the border region of McAllen, Texas—an area marked by economic challenges and cartel violence. His path to cannabis medicine started with Bentley, his beloved dog who was paralyzed and facing euthanasia. When conventional veterinary medicine offered no hope, Colin turned to CBD. The results were nothing short of miraculous: Bentley regained mobility and lived another decade, during which Colin developed specialized cannabis formulas for his evolving health needs.

This experience became the foundation of OilWell Cannabis. Today, our products serve everyone from Marshalltown farmers managing arthritis to Iowa State University students dealing with anxiety, from cancer patients in Marshalltown’s UnityPoint Health system to veterans at the nearby Iowa Veterans Home in Marshalltown.

Our Connection to Iowa

While based in Houston, Texas, OilWell Cannabis has deep ties to the Midwest:

  • Farm Bill compliance: Our products are legal in all 50 states, including Iowa
  • Shipping to Marshall County: We deliver to Marshalltown, Albion, Liscomb, and everywhere in between
  • Veteran focus: Our Asshole Peach gummies are particularly popular with veterans
  • Agricultural roots: We understand the farming community’s values of hard work and self-reliance

The OilWell RSO Difference: What Makes Our Formula Unique

1. Seven Cannabinoids for Comprehensive Support

Unlike traditional RSO that was THC-dominant, our formula contains seven carefully balanced cannabinoids:

Cannabinoid Amount (30mL bottle) Benefits for Marshall County Residents
CBD 4,500mg Anxiety relief, pain management, neuroprotection
CBG 3,000mg Neuroprotective, anti-inflammatory, digestive support
Delta-8 THC 6,000mg Pain relief with milder psychoactive effects than delta-9
THCa 1,500mg Anti-inflammatory, neuroprotective (non-psychoactive when raw)
Delta-9 THC 90mg Pain relief, nausea control, appetite stimulation
CBN 750mg Sleep support, potential neuroprotection
CBC 750mg Anti-inflammatory, potential neurogenesis

This multi-cannabinoid approach leverages the entourage effect, where compounds work synergistically for greater therapeutic potential.

2. Patient-Controlled Potency

One of our most innovative features is the ability to control whether your RSO is psychoactive or not:

  • Raw (non-psychoactive): Use the oil as-is for daytime relief without impairment
  • Decarboxylated (psychoactive): Heat at 260°F for 45-60 minutes to convert THCa to THC
  • Vape format: Instant decarboxylation with each inhalation

This flexibility is particularly valuable in Marshall County, where many residents need to maintain functionality for work, family, and daily activities.

3. Solvent-Free Production

Unlike traditional RSO made with naphtha or isopropyl alcohol, our products use:

  • Organic MCT oil as a carrier
  • Food-grade extraction methods
  • Third-party lab testing for potency and purity

4. Live Terpenes for Enhanced Benefits

We include seven carefully selected terpenes at 5% concentration:

Terpene Aroma Potential Benefits
Limonene Citrus Mood enhancement, stress relief
Myrcene Earthy, musky Relaxation, potential sedative effects
Caryophyllene Peppery, spicy Anti-inflammatory, pain relief
Pinene Pine Alertness, memory support
Linalool Floral, lavender Calming, anxiety relief
Humulene Earthy, woody Anti-inflammatory, appetite suppressant
Terpinolene Piney, herbal Antioxidant, potential sedative effects

These terpenes not only enhance the sensory experience but may contribute to the entourage effect, potentially improving therapeutic outcomes.

5. Open-Source Formulas

In the spirit of Rick Simpson’s original free-distribution model, we publish our complete formulas. If you can’t afford our professionally made products, you can source the ingredients and make your own version at home.

Local connection: Our Peace Gummies were developed from Colin’s personal experience with PTSD and benzo withdrawal.

The Science Behind Our Formula

Cannabinoid Evidence Profiles

CBD (4,500mg)

  • Strongest evidence: Epilepsy (FDA-approved Epidiolex)
  • Emerging evidence: Anxiety (2024 meta-analysis showed significant anxiolytic effects)
  • Pain research: Promising but heterogeneous results

CBG (3,000mg)

  • Mechanistic interest: CB1/CB2 receptors, alpha-2 adrenoceptors, 5-HT1A
  • Research areas: Neuroprotection, inflammatory bowel disease, antibacterial
  • 2024 human trial: 20mg CBG significantly reduced anxiety

Delta-8 THC (6,000mg)

  • Pharmacology: Similar to delta-9 but less potent
  • Safety: Less robustly characterized than delta-9
  • Manufacturing: Often synthesized, raising quality concerns

THCa (1,500mg)

  • Non-psychoactive when raw: Converts to THC when heated
  • Potential benefits: Anti-inflammatory (COX-2 inhibition), neuroprotective (PPARγ agonism)

Delta-9 THC (90mg)

  • Best supported: Chemo nausea, appetite stimulation in HIV/AIDS
  • Pain evidence: May provide short-term benefit but with side effects
  • Risks: Anxiety, tachycardia, dependency potential

CBN (750mg)

  • Sleep reputation: Widespread marketing claims
  • Evidence: Limited—no strong clinical trials yet
  • 2023 study: CBN promotes sleep in rodents/humans via CB1R

CBC (750mg)

  • Emerging research: Anti-inflammatory, antibacterial, anti-seizure
  • Safety: Over-the-counter products already sold despite limited evidence

Terpene Science

While terpene research is still developing, preclinical evidence suggests:

  • Limonene: Antioxidant, anti-inflammatory, mood-enhancing
  • Myrcene: Sedative effects in animal studies
  • Caryophyllene: Only terpene that directly activates CB2 receptors
  • Pinene: May improve alertness and memory
  • Linalool: Calming effects in preclinical studies

Real Stories from Iowa

Supporting a Marshalltown Cancer Patient

When Sarah, a 58-year-old Marshalltown resident, was diagnosed with breast cancer, she turned to our RSO for support during chemotherapy:

“The nausea was unbearable with my first round of chemo. My oncologist in Des Moines suggested I try cannabis, but Iowa’s medical program didn’t have what I needed. OilWell’s RSO changed everything. The vape cartridge stops nausea within minutes, and the sublingual oil helps me sleep through the night. I can actually eat again and keep food down.”

Sarah uses:

  • 0.5mL sublingual before chemo appointments
  • Vape cartridge for breakthrough nausea
  • 1.0mL sublingual at bedtime for sleep

Managing Chronic Pain in Rural Marshall County

Tom, a 62-year-old farmer from rural Marshall County, has battled back pain for years:

“I’ve tried everything—physical therapy, opioids, steroid injections. Nothing gave me lasting relief without side effects. With OilWell’s RSO, I can work all day using the raw oil, then switch to the activated version at night. It’s the first thing that’s given me real control over my pain.”

Tom’s routine:

  • 0.3mL raw sublingual in the morning
  • Additional 0.2mL doses as needed during work
  • 0.7mL decarboxylated oil at bedtime

Veterans Finding Relief

Several veterans from the Iowa Veterans Home in Marshalltown have found relief with our products:

“After 20 years in the Army, my body’s a mess. The VA had me on so many pills I was like a zombie. OilWell’s products let me manage pain and PTSD without feeling drugged. The Peace Gummies help with anxiety, and the RSO vape stops panic attacks fast.”
