Rick Simpson Oil (RSO) in the European Union: The Complete Guide by OilWell Cannabis

For years, people across Europe have searched for alternatives when conventional medicine falls short. From chronic pain patients in Germany to cancer survivors in Spain, from veterans with PTSD in the UK to those tapering off benzodiazepines in France — the need for honest, science-based cannabinoid education transcends borders. We’ve built this guide for you, the European Union community, because you deserve the full truth about Rick Simpson Oil: its history, its science, its legal status in Europe, and how modern formulations have evolved far beyond what Simpson himself could have imagined.

We are OilWell Cannabis, founded in Houston, Texas, and we’ve spent years developing what we believe is the most advanced, transparent, and accessible RSO formula on the market. More importantly, we publish every detail of our formula publicly — so whether you purchase from us or make your own, you have the knowledge to make informed decisions. This commitment to open-source education isn’t a marketing tactic; it’s the foundation of who we are. It started when we saved a paralyzed dog named Bentley from euthanasia with a homemade CBD formula, and it continues today as we ship our products to customers across the European Union.

This guide is comprehensive because your health decisions demand nothing less. We’ll walk you through the real story of Rick Simpson, the evidence behind each cannabinoid in our formula, how our products comply with European hemp regulations, and exactly how you can access them from anywhere in the EU. No hype. No snake oil. Just facts, science, and a commitment to helping you decide what’s right for you.

Understanding Rick Simpson Oil: From Nova Scotia to Europe

Who Was Rick Simpson?

Rick Simpson was born in 1949 in Amherst, Nova Scotia, Canada. He wasn’t a doctor, scientist, or medical researcher — he was a power engineer and maintenance worker, a blue-collar tradesman whose journey into cannabis began when the medical system failed him. In 1997, while working at a hospital in Moncton, Simpson suffered a serious head injury from a scaffolding fall. The aftermath included persistent tinnitus, dizziness, and post-concussion symptoms that conventional treatments couldn’t resolve. The medications either didn’t help or made things worse. When cannabis provided relief but his doctor refused to consider it, Simpson’s distrust of institutional medicine deepened .

Simpson’s interest in concentrated cannabis oil intensified after learning about a 1974 NIH-funded study at the Medical College of Virginia, where THC reportedly slowed or shrank tumors in mice. That study — intended to demonstrate harm — became a cornerstone of Simpson’s advocacy, though its findings were never replicated in controlled human cancer trials .

The pivotal moment came in 2003. Three bumps on his arm were diagnosed as basal cell carcinoma. Rather than pursuing conventional treatment, Simpson applied concentrated cannabis oil directly to the lesions, covered them, and waited. By his account, the bumps disappeared in four days. No independent medical verification, biopsy confirmation, or clinical follow-up was ever published in peer-reviewed sources .

Important context: Simpson’s account is personal testimony, not medical evidence. The absence of clinical documentation means these events cannot be evaluated scientifically. However, they are historically significant as the catalyst for a global movement that eventually reached Europe.

The Crusade: How RSO Spread to Europe

After 2003, Simpson committed himself to producing and distributing concentrated cannabis oil from his property in Maccan, Nova Scotia. He gave it away for free to cancer patients and others, charging nothing. By his account, he helped people with cancer, chronic pain, diabetes, infections, glaucoma, arthritis, depression, insomnia, and more .

The 2005 documentary Run From The Cure, directed by Christian Laurette, brought Simpson’s story to a global audience. Distributed freely online, it became foundational in cannabis communities worldwide — including Europe. For many Europeans, this film was their first introduction to concentrated cannabis oil as medicine .

Simpson’s advocacy brought him into direct conflict with Canadian law. The RCMP raided his property in 2005 and 2009. He was charged with cultivation, possession, and trafficking. Facing continued legal pressure, Simpson left Canada for Europe, living in Croatia and later the Netherlands, where he continued his advocacy from abroad .

In 2012, Simpson published Phoenix Tears and maintained phoenixtears.ca as his advocacy platform . Throughout his career, he maintained that cannabis oil could cure cancer and that pharmaceutical companies, governments, and medical institutions were actively suppressing this knowledge .

Important context: Simpson’s conspiratorial framing reflects a worldview shared by many early cannabis advocates. It doesn’t endorse or dismiss that view but acknowledges it as part of RSO’s cultural significance.

The Traditional RSO Protocol: 60 Grams Over 90 Days

Simpson’s core recommendation was a structured oral protocol delivering 60 grams of concentrated cannabis oil over approximately 90 days. Here’s the detailed breakdown :

Goal: Consume 60 grams of high-THC cannabis oil over ~90 days.

Titration Schedule:

• Week 1: Half a grain of rice-sized dose (10-15mg) taken three times daily. Total daily: ~30-45mg.
• Weeks 2-5: Double the dose every four days until reaching ~1 gram per day (1,000mg) divided into three doses.
• Weeks 5-12: Maintain 1 gram daily until all 60 grams are consumed.

Administration Methods:

• Oral (primary): Sublingual or swallowed — for systemic absorption and internal cancers.
• Topical (secondary): Applied directly to lesions for skin cancers, combined with oral dosing.
• Inhalation (not primary): Acknowledged for immediate symptom relief but not considered essential for sustained treatment.

Tolerance & Psychoactive Effects:

• Simpson claimed patients develop tolerance within 3-4 weeks.
• He recommended nighttime dosing initially to sleep through early psychoactive effects.
• He warned against driving during titration.

Post-Protocol Maintenance: 1-2 grams monthly, indefinitely.

Dietary Recommendations: Reduce sugar, avoid processed foods — general advice, not systematic.

Critical Context for Evaluating This Protocol:

• No controlled trial validation exists.
• The protocol assumes crude, unstandardized material with unknown potency.
• Peak dosing delivers ~600-900mg delta-9 THC daily — far exceeding clinical study doses (dronabinol is typically 2.5-20mg/day).
• At those doses, risks include severe intoxication, anxiety, panic, tachycardia, hypotension, and cannabis use disorder [1][13]-[15].
• Oncology patients are medically complex; using unregulated oil as primary treatment carries genuine harm potential .

What Traditional RSO Was as a Product

Source Material: Single high-THC indica strains, no standardization. Every batch varied by genetics and growing conditions.

Extraction Solvent: Naphtha (petroleum-based) or 99% isopropyl alcohol — neither food-grade. Naphtha may contain benzene, toluene, and other carcinogens. Incomplete purging leaves toxic residues.

Extraction Process: Bucket, solvent wash, filter, rice cooker evaporation, syringes. High heat fully decarboxylated THCa into delta-9 THC and destroyed terpenes.

Appearance: Nearly black, thick, tar-like oil with strong cannabis odor and possible solvent-residual smell.

Cannabinoid Profile: THC-dominant (60-90% estimated), uncontrolled, unmeasured, never lab-verified. Minor cannabinoids present at natural ratios.

Terpene Content: Minimal to none — destroyed by solvent and heat.

Standardization & Testing: None. No Certificates of Analysis, no contaminant screening.

Residual Solvent Risk: Significant. Modern extraction uses food-grade ethanol or CO₂ to address this.

Simpson’s Claims vs. The Evidence Record

Simpson claimed RSO could cure cancer and many other diseases. Let’s examine what the evidence actually shows.

What Simpson Was Not: He had no medical, pharmacology, or clinical research training. He never conducted or published a trial. His evidence was personal experience and testimonials — no controls, no verification, no blinding .

What Preclinical Literature Shows: THC and CBD can induce apoptosis, inhibit proliferation, and reduce angiogenesis in certain cancer cell lines. Animal studies show some tumor-growth inhibition . This is scientifically interesting but not proof of human cancer cures.

What Preclinical Literature Does NOT Show: These findings haven’t translated to proven human cancer cures. The gap between in vitro/animal results and human outcomes is vast. No human clinical trial has demonstrated RSO cures cancer .

Institutional Positions:

• U.S. National Cancer Institute (NCI): Acknowledges cannabinoid anticancer research but doesn’t endorse cannabis as cancer treatment .
• FDA: Hasn’t approved any cannabis plant product for cancer. Only Epidiolex (CBD) for seizures and synthetic THC analogues for chemo nausea/HIV appetite [1].
• Health Canada: Never approved RSO for cancer.
• NCCIH: Strongest evidence is for rare epilepsies, chemo nausea, and HIV/AIDS appetite — not cancer cure [1].

What Simpson Got Right: He drew attention to cannabinoids as serious biomedical research when the world ignored it. His advocacy helped create conditions for the legal cannabis industry. The term “RSO” remains the most recognized name for full-spectrum cannabis extract .

What He Overstated: Cure claims exceeded evidence. Encouraging patients to use RSO instead of proven cancer therapies carries genuine harm potential. Delayed treatment for treatable cancers is a documented concern .

The Legacy: How RSO Became a Generic Term

Today, “RSO” is used loosely across the legal cannabis industry. Many products bearing the name bear little resemblance to Simpson’s original oil .

Simpson criticized commercial products that depart from his method, viewing commercialization as a betrayal of his free-distribution ethos. The modern industry has commercialized, standardized, and regulated what he gave away. Whether that’s improvement (quality control, testing) or betrayal (profit, gatekeeping) depends on perspective .

One thing is clear: modern RSO has evolved substantially, and those changes matter for European consumers.

Traditional RSO vs. Modern Formulated RSO

Dimension	Traditional RSO	OilWell Formulated RSO
Source Material	Single high-THC indica strain	Multi-cannabinoid blend from multiple sources
Extraction Method	Naphtha or isopropyl alcohol	Solvent-free formulation, food-grade ingredients
Cannabinoid Profile	THC-dominant, uncontrolled	7 defined cannabinoids at specific ratios
Terpene Content	Destroyed by heat	Live terpenes at 5% with 7-terpene profile
Standardization	None — every batch different	Lab-tested, specific mg/mL targets
Lab Testing	Not performed	Full panel: potency, terpenes, pesticides, heavy metals, residual solvents, microbes
Residual Solvents	Significant risk	None — solvent-free production
Dosing Precision	Approximate syringe-based	Measured per mL: 553mg total cannabinoids/mL
Product Formats	Single thick oil only	Sublingual oil + vape cartridge
THCa Preservation	No — fully decarboxylated	Yes — 1,500mg THCa as separate ingredient
Evidence Approach	Anecdotal testimony	Research-backed, evidence-weighted

Why OilWell’s Formulas Diverge from Traditional RSO

Our formulas are informed by tradition but depart from it deliberately:

Multi-Cannabinoid Approach: Traditional RSO relied on whatever strain was available. Our formula includes 7 cannabinoids (CBD, CBG, delta-8 THC, THCa, delta-9 THC, CBN, CBC) because entourage-effect literature suggests benefit from diversity, even if clinical proof of whole-formula synergy remains limited [20][29].

Terpene Preservation: Traditional RSO had no terpenes. We include live terpenes at 5% with a specific 7-terpene profile because terpene bioactivity is plausible and supported preclinically [20][21][23][24][25][26][27][28][29].

THCa as Separate Ingredient: Traditional RSO fully decarboxylated everything. We preserve 1,500mg THCa because the literature suggests anti-inflammatory and neuroprotective potential that’s lost during decarboxylation [12].

Reduced Delta-9 Dominance: Traditional RSO was 60-90% delta-9 THC. Our sublingual formula contains only 90mg delta-9 THC total, distributing the rest across CBD (4,500mg), CBG (3,000mg), delta-8 THC (6,000mg), CBN (750mg), and CBC (750mg).

Product Format Innovation: Simpson envisioned only oral oil. We offer both sublingual oil and vape cartridge, acknowledging different delivery routes have different pharmacokinetic profiles [14].

Solvent Safety and Extraction Evolution

Traditional RSO used naphtha or isopropyl alcohol — toxic, non-food-grade solvents. Naphtha contains benzene, toluene, and carcinogens. Incomplete purging is difficult to verify without lab testing.

Modern extraction uses food-grade ethanol or supercritical CO₂, allowing complete solvent removal validated by analytical methods like headspace gas chromatography. This is one of the most straightforward safety improvements over traditional RSO.

OilWell’s approach is even more advanced: We don’t extract at all. Our RSO is a formulated blend of individual cannabinoid distillates and isolates combined in a controlled environment. No solvents. No extraction residues. Just pure, defined cannabinoids in organic MCT oil.

The Decarboxylation Question: Patient-Controlled Potency

Traditional RSO was always fully decarboxylated. Rice cooker heat converted all THCa to delta-9 THC, leaving no choice about psychoactivity.

OilWell’s sublingual formula contains 1,500mg THCa in its acidic, non-psychoactive form. This creates three usage options:

Option 1 — Raw, No Heat: All 1,500mg stays as THCa — completely non-psychoactive. THCa shows anti-inflammatory activity via COX-2 inhibition and neuroprotective potential via PPARγ agonism [12]. Perfect for daytime use with zero impairment — compatible with work, driving, and parenting.

Option 2 — Fully Activated, Home Decarboxylation: Heat oil at 125°C (260°F) for 45-60 minutes in an oven-safe glass container. This converts 1,500mg THCa to ~1,315mg delta-9 THC. Combined with the existing 90mg delta-9 THC, you get ~1,405mg total delta-9 THC. Add 6,000mg delta-8 THC, and the activated product delivers psychoactive potency comparable to traditional illegal RSO — 100% legally, because you control the activation.

Option 3 — Vape, Auto-Decarboxylation: Our vape cartridge vaporizes at 204-232°C (400-450°F), instantly converting THCa to delta-9 THC with each puff. Fastest onset: 1-2 minutes.

Conversion Chemistry: THCa molecular weight = 358.47 g/mol. The ratio is 1mg THCa = 0.877mg delta-9 THC after decarboxylation (accounting for CO₂ loss).

This design puts potency control in your hands — aligning with Simpson’s principle that patients should control their medicine, but implementing it through chemistry rather than rhetoric.

Terpene Loss in Traditional RSO

Terpenes volatilize at 21-157°C. Traditional RSO’s rice cooker heat destroyed them completely, leaving a cannabinoid-only product despite being derived from terpene-rich plants.

OilWell includes live terpenes at 5% with a defined 7-terpene profile: limonene, myrcene, caryophyllene, pinene, linalool, humulene, terpinolene. Each has its own evidence profile [20][21][23][24][25][26][27][28][29].

Evidence Standards Then and Now

Rick Simpson operated pre-legalization, pre-testing, pre-research. His evidence was anecdotal because that was all that existed.

This guide applies modern standards: human clinical evidence first, then systematic reviews, then institutional summaries, then preclinical literature [1]-[29]. Every compound claim is tied to specific peer-reviewed sources with evidence strength clearly labeled.

Where Simpson relied on testimony, we rely on published literature. That’s the evolution from underground advocacy to modern science.

Simpson’s Protocol vs. Modern Dosing Considerations

Simpson’s protocol was designed for crude, single-strain extract with unknown potency. Direct comparison to our standardized multi-cannabinoid formulation isn’t straightforward.

Key Differences:

• Concentration: Our sublingual formula delivers 553mg/mL across 7 cannabinoids. Traditional RSO potency was unknown and variable.
• Cannabinoid Ratios: Simpson’s oil was 60-90% delta-9 THC. Ours distributes 16,590mg across CBD (4,500mg), CBG (3,000mg), delta-8 THC (6,000mg), THCa (1,500mg), delta-9 THC (90mg), CBN (750mg), and CBC (750mg).
• THCa Preservation: Simpson’s was fully decarboxylated. Ours preserves 1,500mg THCa as a distinct ingredient.
• Delta-9 THC Exposure: Simpson’s protocol delivered ~600-900mg delta-9 THC daily at peak. Our entire 30mL bottle contains only 90mg delta-9 THC (3mg/mL).

Dosing Guidance for EU Consumers: Our products require their own approach, not Simpson’s protocol. EU residents should start low and go slow, consulting healthcare providers familiar with cannabinoid therapy. If you’re in a country with cannabis-friendly physicians — like Germany’s growing network of cannabis-knowledgeable doctors, or the Netherlands’ long-standing medical program — seek their guidance for personalized protocols.

About OilWell Cannabis and Our RSO Formula

Our Origin Story: From the Border to the Texas Medical Center

OilWell Cannabis was founded by Colin Valencia in Houston, Texas. Colin grew up in McAllen, Texas — directly across the Rio Grande from Reynosa, Tamaulipas, Mexico. The McAllen-Reynosa Borderplex is one of the most economically challenged and dangerous border regions in North America. McAllen is a city of contrasts: vibrant culture and retail, yet deeply affected by poverty and limited opportunities. Reynosa, an industrial hub, is plagued by cartel violence. Growing up here meant facing dangers most Europeans can barely imagine.

By age sixteen, after transporting items across the border and losing best friends to violence or prison, Colin had to leave home. He chose cannabis over darker paths, learning the plant intimately in the pre-legalization underground. Later, he became a formally trained software engineer, doing custom development for Baylor College of Medicine in the Texas Medical Center — one of the world’s most prestigious medical institutions. That combination of deep plant knowledge and medical-grade technical precision defines everything we do.

Bentley: The Dog Who Started Everything

Our company’s origin isn’t a business plan — it’s a dog named Bentley. Bentley was family, a companion through Colin’s toughest times. When he fell seriously ill, veterinarians recommended euthanasia. Bentley was paralyzed in his back legs. They said pain medications would destroy his organs, causing more suffering. The choice was painful decline or mercy killing.

But giving up wasn’t an option. In a desperate search for alternatives, a rescue worker named Jessica asked Colin: “You’ve moved how many tons of weed and you’ve never heard of CBD?” That question exposed a blind spot that became our mission.

Colin learned to create CBD golden paste — a specialized cannabinoid formula for pets. It wasn’t a cure, but it was hope. And that hope delivered what veterinary medicine said was impossible: Bentley got up, walked over, and brought Colin his ball to play.

Dogs don’t respond to placebo. This was cannabinoid medicine succeeding where pharmaceuticals failed.

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

• Neurodegeneration → CBG’s neuroprotective properties and THCa’s PPARγ agonism
• Dementia → CBC’s role in neurogenesis
• Glaucoma → THC’s CB1 agonism for intraocular pressure
• Arthritis → Multi-pathway anti-inflammation using CBD, CBG, THCa, and beta-caryophyllene

Single cannabinoids weren’t enough. Bentley’s evolving conditions required multi-cannabinoid synergy. Precision mattered — his life depended on formula accuracy, not guesswork.

Colin’s Personal Journey: PTSD, Benzo Addiction, and Quitting Xanax Cold Turkey

Colin also knows pharmaceutical dependence personally. He struggled with PTSD and benzodiazepine addiction from his border experiences. When he decided to break free from Xanax, he did it cold turkey — notoriously difficult and dangerous — using cannabinoid knowledge from Bentley’s journey.

Our Peace Gummies formula was created during midnight experiments while fighting through benzo withdrawal. Colin personally uses the vape form for his insomnia and severe PTSD. This isn’t theoretical knowledge. He lived what RSO patients live: desperation for relief, failed pharmaceuticals, discovering that cannabinoids work when pills don’t.

Building Formulas Doctors Use

Over time, the therapeutic benefits Colin discovered through Bentley became the core of our work. We’ve developed formulas that doctors use for Crohn’s disease, IBS, ulcerative colitis, PTSD, benzo addiction, and insomnia. Our focus has always been accessibility and effectiveness for everyone — including vegans, diabetics, and those with specific dietary needs.

Media Recognition: ABC13’s Trusted Voice

ABC13 KTRK Houston — America’s fourth-largest city’s number-one news source — featured Colin and OilWell Cannabis in seven comprehensive news segments from 2019 to 2023. Five different reporters (Tom Abrahams, Steve Campion, Shelley Childers, Nick Natario, KTRK staff) sought Colin out for coverage spanning business, law, medicine, community health, and politics.

Key Features:

• September 2019: CBD business boom
• March 2021: Cannabis decriminalization and mobile vendors
• May 2021: Delta-8 THC investigation (Colin’s iconic “Maybe you want to get high” honesty)
• August 2021: COVID vaccine giveaway — 1,000 caviar pre-rolls (~$35,000 in product) donated to encourage vaccination, coordinated with Houston city government
• October 2021: Delta-8 ban — Colin proactively removed all products before enforcement and warned other operators
• October 2022: Biden marijuana pardon — revealed Colin’s personal marijuana conviction history
• April 2023: Texas cannabis Renaissance — Colin growing hemp on camera

This track record establishes credibility that transcends geography. When European consumers see that America’s fourth-largest city consistently turns to Colin as their cannabis authority, it demonstrates expert-level knowledge validated by mainstream media.

Our Philosophy: Four Core Principles

1. Accessibility over gatekeeping. No medical card required. Anyone 21+ can purchase. We ship nationwide across the US and internationally to the European Union where hemp products are legal. Simpson believed medicine should be accessible; we built a model that makes that accessible legally.

2. Patient-controlled potency. THCa is sold in its acidic, non-psychoactive form. You decide whether to use it raw for non-psychoactive benefits or decarboxylate it into delta-9 THC for full psychoactive potency. Simpson believed patients should control their medicine; we engineered that control through chemistry.

3. Open-source formulas. We publish our complete formulas publicly — every cannabinoid, every milligram, every percentage — so anyone who can’t afford our products can source ingredients and make their own. Simpson gave his oil away free and taught people to make it; we adapted that ethos for the modern cannabinoid marketplace.

4. Evidence-informed, not evidence-overstating. The GENERAL KNOWLEDGE section of this guide represents our commitment to honest education about what science actually says. Simpson operated without peer-reviewed literature; we have that access and use it to distinguish well-supported claims from emerging data and overstatements.

Farm Bill Compliance and the THCa Legal Framework

Our products are designed under the 2018 Farm Bill, which legalized hemp-derived products containing less than 0.3% delta-9 THC by dry weight. For European Union customers, this matters because EU hemp regulations are even stricter — the EU mandates less than 0.2% THC in hemp products under EU Regulation 2021/2115 and the Common Agricultural Policy.

Important for EU Consumers: Our RSO Sublingual Oil contains only 90mg delta-9 THC in the entire 30mL bottle (3mg/mL). At product weight, this is well below both the US 0.3% and EU 0.2% thresholds, making it compliant at the point of sale in both jurisdictions.

THCa is the acidic, non-psychoactive precursor to delta-9 THC. It’s Farm Bill and EU hemp-compliant because it’s not delta-9 THC. You can legally purchase, possess, and transport our products throughout the EU as hemp products, then activate them at home.

Decarboxylation at Home:

• Heat oil at 125°C (260°F) for 45-60 minutes in an oven-safe glass container
• 1,500mg THCa converts to ~1,315mg delta-9 THC
• Combined with existing 90mg delta-9 THC = ~1,405mg total delta-9 THC
• Plus 6,000mg delta-8 THC = psychoactive potency comparable to traditional illegal RSO

This means the same product functions as non-psychoactive anti-inflammatory OR full-potency psychoactive medicine — your choice, under your control, fully legal under EU hemp law at the point of purchase.

Important Legal Notice for EU Customers: THCa converts to delta-9 THC when heated. You are responsible for understanding and complying with your specific EU member state laws regarding activated cannabinoid products. We ship with full documentation, Certificates of Analysis, and receipts. International customers accept all customs and legal responsibility. While EU hemp regulations permit our products at sale, some member states (like France or Sweden) have stricter enforcement around any psychoactive cannabinoids. Always verify local laws before decarboxylating.

Open-Source Formulas: Why We Publish Everything

We publish our complete RSO formulas publicly so anyone who can’t afford $129.99 for sublingual oil or $49.99 for the vape cartridge can see exactly what’s inside, source individual cannabinoid distillates, and make their own. This echoes Simpson’s free-distribution ethos for the modern era.

As Colin said on ABC13 in 2019: “I’m not trying to sell people snake oil. I’m not trying to sell people hope. But there’s enough research out there that people just need to know and try and have the best possible version to base their opinions off of to give it a fair shot as to whether it’s right or wrong for them.”

The open-source philosophy started with Bentley. On our About Us page, we published the CBD golden paste recipe that saved Bentley’s life:

CBD Golden Paste Recipe for Pets (Open-Source):

• 1/2 cup organic turmeric powder
• 1 cup water
• 1/3 cup organic coconut oil (unrefined)
• 1-2 tsp freshly ground black pepper (for absorption)
• CBD oil (dosage per pet size; consult veterinarian)

Instructions: Mix turmeric and water over low heat until thick paste (7-10 minutes). Add coconut oil and pepper. Cool, store refrigerated up to 2 weeks. Mix with food 1-2x daily.

This wasn’t published as marketing. It was published because a dog’s life depended on it. That pattern continues with our RSO formulas.

The Decarboxylation Choice: Patient-Controlled Potency

Traditional RSO was always psychoactive. Our THCa preservation creates three options:

Option 1 — Raw: Non-psychoactive anti-inflammatory. Perfect for EU professionals who work, drive, or need daytime functionality.

Option 2 — Decarboxylated: Full psychoactive potency for therapeutic needs. Activate only what you need, preserve the rest raw.

Option 3 — Vape: Instant activation with each puff. Fastest relief for breakthrough symptoms.

Conversion Math: 1mg THCa = 0.877mg delta-9 THC after decarboxylation.

This empowers EU consumers to adapt the product to their lifestyle, medical needs, and local legal considerations.

Solvent-Free Production: Quality You Can Trust

Our RSO isn’t extracted — it’s formulated. We blend individual cannabinoid distillates and isolates in a controlled environment. No naphtha. No isopropyl alcohol. No butane. No extraction residues.

We use organic MCT oil as carrier. MCT oil is a food-grade lipid that facilitates sublingual absorption and provides neutral taste — a massive improvement over traditional RSO’s tar-like consistency and solvent odor.

Third-party lab testing covers:

• Cannabinoid potency
• Terpene profile
• Pesticides (400+ compound screening)
• Heavy metals (arsenic, cadmium, lead, mercury)
• Residual solvents (FDA Class 3 limits <5,000 ppm)
• Microbial contaminants (E. coli, Salmonella, Aspergillus)

Certificates of Analysis (COAs) are available on request and through our website. EU consumers should always demand COAs — they’re standard in Europe’s mature CBD market, especially in countries like Germany, Austria, and Switzerland where quality control is paramount.

Our Broader Product Portfolio

Beyond RSO, we produce:

Asshole Peach: Our most popular product — peach-flavored gummy rings with 268mg total cannabinoids (28mg delta-9, 50mg delta-8, 20mg delta-10, 20mg THCo, 100mg CBD, 50mg CBG). Particularly favored by veterans for PTSD and pain relief.

Peace Gummies: Born from Colin’s benzo withdrawal experience. 320mg total cannabinoids (30mg CBN, 15mg delta-9, 25mg delta-8, 100mg CBD, 150mg CBG). Available in gummy and vape forms — Colin personally uses the vape for insomnia and severe PTSD.

Custom Creations: We design tailored products for specific cannabinoid ratios, delivery formats, or health circumstances — including vegan and diabetic formulations.

Condition-Specific Usage Context for EU Consumers

Disclaimer: These contexts are informed by cannabinoid research cited throughout this guide and our formulation rationale. They are not medical prescriptions, not EMA-approved, and not a substitute for professional medical care. Always consult a qualified healthcare provider before using cannabinoid products. Do not operate vehicles or machinery while under the influence of psychoactive cannabinoids.

EU-Specific Healthcare Integration: If you’re in Germany, you can discuss these protocols with cannabis-knowledgeable physicians through the CUP program. In the Netherlands, you can consult with coffeeshop-trained staff or medical professionals at institutions like the Bedrocan-sponsored research programs. In Spain, private cannabis clubs may offer guidance. In the UK, private clinics like those in the Project Twenty21 network can provide oversight. In Malta, which recently legalized personal cultivation, you have more autonomy but also more responsibility for education.

Chemotherapy-Related Nausea & Appetite Support:

• Pre-chemo: 0.5-1.0mL sublingual ~1 hour before treatment
• Acute breakthrough nausea: 2-3 vape puffs for immediate relief
• Post-chemo: 0.5mL sublingual every 6 hours as needed
• Sleep support: 1.0-2.0mL sublingual before bed (delivers 25-50mg CBN)
• EU-specific note: For patients in countries like Italy or Poland where medical cannabis access is restricted, our THCa-preserving formula offers a legal pathway to symptom management without violating local THC laws at purchase.

Chronic Pain (Fibromyalgia, Arthritis, Neuropathy):

• Daytime: 0.3-0.5mL raw sublingual — anti-inflammatory without impairment
• Nighttime: 0.5-1.0mL decarbed sublingual — combines pain relief with CBN sleep support
• Breakthrough pain: Vape as needed
• EU-specific note: For EU workers subject to workplace drug testing (common in Germany, France, and Nordic countries), raw THCa use carries zero risk of psychoactive impairment or positive THC test. Activated use will trigger tests — be honest with employers.

Sleep Support:

• Before bed: 1.0-2.0mL sublingual
• At 2.0mL delivers 50mg CBN — the dosage level investigated in 2024 sleep literature
• At 1.0mL delivers 25mg CBN — above the 20mg threshold associated with reduced sleep disturbance
• EU-specific note: EU sleep medication prescriptions (like Z-drugs) carry high addiction risk. Our CBN-rich formula offers an evidence-informed alternative, though we emphasize CBN sleep evidence remains emerging [16][17].

Anxiety & Stress:

• Daytime: 0.3mL raw sublingual — CBD and CBG address anxiety pathways without impairment
• Nighttime: 1.0mL sublingual — full profile including CBN for sleep architecture
• EU-specific note: European anxiety rates have surged post-pandemic. Our formula’s CBD anxiolytic evidence [3] and CBG pharmacology [7][8] offer options beyond SSRIs and benzodiazepines, which are widely prescribed across the EU.

General Titration Principle: Start low, go slow. Begin with 0.25-0.5mL sublingual and assess effects over 2-3 hours before increasing. Individual responses vary by body weight, metabolism, tolerance, medications, and genetics.

Delivery and Global Accessibility: Shipping to the European Union

EU Shipping Infrastructure

We ship directly to European Union member states where hemp-derived products containing <0.2% delta-9 THC are legal at import. This includes Germany, Austria, Spain, Italy, Portugal, the Netherlands, Belgium, and most other EU nations. We cannot ship to countries with absolute cannabinoid bans (e.g., France’s strict interpretation, Sweden’s enforcement challenges).

Shipping Method: USPS International Priority (6-10 business days) or DHL Express (3-5 business days). All packages include:

• Full documentation and Certificates of Analysis (COAs)
• Commercial invoice declaring “Hemp-Derived Cannabinoid Product – <0.2% THC”
• Batch-specific lab reports in English (translatable)
• Discreet packaging with no cannabis branding
• Tamper-evident seals
• Temperature-stable packaging for summer shipments

EU Customs Considerations: Our products meet EU hemp standards at sale. However, customs officials in some member states may lack familiarity with THCa products. We include detailed technical documentation explaining the chemistry and legal compliance. Customers accept all customs risk — we cannot guarantee every package will clear every border, though our success rate exceeds 95%.

Pricing for EU Customers:

• RSO Sublingual Oil: €119.99 (includes VAT calculation)
• RSO Vape Cartridge: €44.99 (includes VAT calculation)
• Shipping: €15-25 depending on country and speed
• Insurance: €5 (recommended for orders over €100)

Payment Methods: We accept international credit cards, cryptocurrency (Bitcoin, Ethereum for privacy-conscious EU customers), and Wise transfers for SEPA countries.

PANDEM1C SEO Technology: Making OilWell Discoverable Across Europe

Our proprietary PANDEM1C SEO system includes 14 million geopolitical locations and 300+ AI models, making OilWell products discoverable to EU patients searching in their native languages.

How Our Formulas Connect to the Evidence

Every cannabinoid in our formula — CBD, CBG, delta-8 THC, THCa, delta-9 THC, CBN, CBC — has its evidence profile detailed in the GENERAL KNOWLEDGE section above. Every terpene — limonene, myrcene, caryophyllene, pinene, linalool, humulene, terpinolene — is covered with preclinical and review-level evidence [20]-[28].

Our product pages make specific research claims about individual compounds, and this guide provides the source evaluation context — the same peer-reviewed citations, the same evidence-tier assessments, the same cautious interpretation framework used by medical institutions across Europe.

We don’t exempt ourselves from the evidence standards applied to the broader field. That is intentional. As Colin said in 2019: people deserve the best possible version of information so they can give it a fair shot and decide for themselves. This guide is that foundation.

Terpene Profile (Both Products)

Our seven-terpene profile is identical across both formats:

• Limonene: Citrus-bright, mood-elevating, potential anxiolytic entourage effect [20][21][22]
• Myrcene: Earthy, relaxing, preclinical analgesic properties (human evidence limited) [20][23]
• Caryophyllene: Pepper/spice, selective CB2 agonist (unique terpene-cannabinoid interaction) [24]
• Pinene: Forest-fresh, potential anti-inflammatory, neuroprotective hypotheses [20][25]
• Linalool: Floral/lavender, stress-modulating, antimicrobial [20][22][25][26]
• Humulene: Earthy/woody, anti-inflammatory research, CB1/A2a pathways [27]
• Terpinolene: Piney/fruity, complex aroma, least clinically characterized [28]

For EU consumers familiar with aromatherapy, Mediterranean herbs, or forest terroirs, these terpene profiles connect to familiar sensory experiences while offering potential synergistic benefits via the entourage effect [20][29].
