Three Things Nobody Tells You
About Traditional RSO
Rick Simpson changed the conversation about cannabis as medicine. We honor that. But the oil he made in 2003 had real problems — and Houstonians deserve better than a 20-year-old recipe made with lighter fluid.
Toxic Solvents
Traditional RSO was extracted with naphtha — a petroleum-based solvent that can contain benzene, toluene, and other known carcinogens. Every batch carried residual solvent risk that couldn't be verified without lab equipment nobody had.
Solvent-Free
We use zero extraction solvents. Our RSO is formulated from individual cannabinoid distillates and isolates blended in organic MCT oil. No naphtha. No isopropyl. No risk. Every batch tested by third-party labs for residual solvents — and the result is always zero.
One Cannabinoid
Simpson's oil was THC-dominant — roughly 60-90% delta-9 THC with whatever minor cannabinoids the plant happened to contain. No terpenes survived the process. No cannabinoid ratios were controlled. No two batches were the same.
Seven Cannabinoids + Seven Terpenes
Our RSO contains CBD, CBG, delta-8 THC, THCa, delta-9 THC, CBN, and CBC — each at specific, lab-verified amounts. Plus seven live terpenes at 5%. Every compound chosen for its evidence profile. Every milligram intentional.
Zero Precision
No Certificate of Analysis. No cannabinoid quantification. No contaminant screening. No dosing control. Simpson recommended doses by the size of "half a grain of rice." That's not medicine — that's guesswork.
553mg/mL Precision
Every milliliter delivers exactly 553mg of total cannabinoids. Graduated dropper measures 0.1mL increments. Full-panel lab testing: potency, terpenes, pesticides, heavy metals, microbials. COAs available for every batch. This is RSO that behaves like real medicine.

CBD (Cannabidiol)
The most evidence-developed nonintoxicating cannabinoid in this formula. Purified CBD has the strongest human evidence in seizure disorders, with a 2024 anxiety meta-analysis showing statistically significant anxiolytic effects across 316 participants. A 2024 pain review found promising but heterogeneous evidence. We include 4,500mg because CBD provides a research-backed foundation that may modulate the effects of other compounds in the formula.

Your RSO, Your Rules
THCa stays non-psychoactive until you add heat. Use it raw for daytime function. Decarboxylate at home for full potency. You control the decision — not the product.
☀️ Raw (No Heat)
🔥 Decarbed (Heated 260°F, 45-60min)
Seven Live Terpenes at 5%
Traditional RSO destroyed every terpene during extraction. We preserved them — because the entourage effect hypothesis suggests these aromatic compounds may work synergistically with cannabinoids. Here's what each one brings.
β-Caryophyllene
The most mechanistically interesting terpene in our formula. β-Caryophyllene is a selective CB2 receptor agonist — meaning it directly activates part of your endocannabinoid system, functioning more like a cannabinoid than a typical terpene. Research describes anti-inflammatory, immunomodulatory, and neuroprotective effects, though human clinical confirmation remains limited. It's the strongest candidate for a terpene with genuine cannabinoid-system significance.

From the Border to Montrose
OilWell Cannabis wasn't born in a boardroom or a focus group. It started with a dog named Bentley, a question that changed everything, and a man who'd already survived more than most people can imagine.
Colin Valencia grew up in McAllen, Texas — right across the Rio Grande from Reynosa, Tamaulipas. The Borderplex is one of the most economically challenged and dangerous regions along the U.S.-Mexico border. A city of contrasts: vibrant culture and deep poverty, thriving retail corridors and cartel violence just across the river.
Colin's childhood was shaped by everything that comes with life along that line. Early on, he learned to hustle — transporting items across the border, navigating dangers that most people only see in documentaries. A lot of his best friends were killed or ended up in prison. He faced every form of violence imaginable, in the streets and across the border. By sixteen, he had to leave home for good.
But Colin didn't fall into the darkest paths available to him. He chose cannabis over harder substances, seeing it as something safer and more beneficial. He grew up in the traditional cannabis world long before legalization, learning the plant intimately while operating in the shadows. That deep plant knowledge — built through years of real experience — would eventually become OilWell's foundation.
Colin became a formally trained software engineer and did custom development work for Baylor College of Medicine — one of the most prestigious medical institutions in the Texas Medical Center. That combination is what defines OilWell's approach: deep cannabis plant knowledge from years on the ground, plus medical-grade technical precision from one of the best medical institutions in the world.
Most cannabis companies have one or the other. OilWell has both. And that duality — street knowledge and institutional rigor — is why the formulas in this RSO exist the way they do.
Bentley was more than a pet. He was family — a companion who stood by Colin through the toughest times. When Bentley fell seriously ill, the veterinarians delivered the verdict no pet owner wants to hear: euthanasia was the only humane option. Bentley was paralyzed in his back legs. They said the pain medications would destroy his internal organs, causing him more suffering. The choice was prolonged pharmaceutical decline or immediate mercy killing.
Giving up on Bentley was not an option. Colin had already faced too much loss and seen too much suffering in his life. Bentley was a fighter, just like him.
A rescue worker named Jessica asked Colin a question that rewired his entire understanding of the plant he'd spent years around:
Colin had cannabis experience — but it was recreational. Getting high. He had never explored the therapeutic and medicinal applications. Jessica's question exposed a blind spot that would become a mission.
Determined to save Bentley, Colin learned to create CBD golden paste — a specialized cannabinoid formula for pets. It was not a cure, but it was a lifeline. And that lifeline delivered something veterinary medicine said was impossible: Bentley got up. He walked over to Colin and brought him his ball to play.
From paralyzed and facing euthanasia to fetching his ball. This was not placebo effect — dogs don't respond to placebo. This was cannabinoid medicine doing what pharmaceuticals could not.
Bentley lived another ten years, passing naturally at age twenty. During those years, Colin developed specialized formulas for every age-related condition Bentley faced. Neurodegeneration led him to understand CBG's neuroprotective properties and THCa's PPARγ agonism. Dementia led him to CBC's role in neurogenesis. Glaucoma led him to THC's CB1 agonism for intraocular pressure. Crippling arthritis led him to multi-pathway anti-inflammatory approaches using CBD, CBG, THCa, and beta-caryophyllene working through different receptor systems simultaneously.
Single cannabinoids were not enough. Bentley's evolving conditions required multi-cannabinoid synergy. CBD alone couldn't address neurodegeneration and dementia and glaucoma and arthritis at the same time. Minor cannabinoids like CBG, CBN, and CBC became critical as Bentley aged. Pharmaceutical precision mattered — Bentley's life depended on formula accuracy, not guesswork.
That decade of real-world, life-or-death formulation testing IS the foundation of OilWell's RSO. The seven-cannabinoid formula didn't come from a marketing brainstorm — it came from keeping a dying dog alive for ten more years through precise cannabinoid science.
Colin also knows pharmaceutical dependence personally. He struggled with PTSD and benzodiazepine addiction. When he decided to break free from Xanax, he did it cold turkey — a feat that is notoriously difficult and dangerous — using the cannabinoid knowledge he had developed keeping Bentley alive.
The Peace Gummies formula that became an OilWell product was created during midnight experiments while fighting through benzo withdrawal. To ensure quick relief, OilWell also offers the Peace Gummies formula in a vape form, which Colin personally uses to manage his insomnia and severe PTSD.
This is not theoretical knowledge. Colin lived what RSO patients live: desperation for relief, failed pharmaceuticals, and the discovery that cannabinoids work when pills do not.
Today, OilWell Cannabis operates from the heart of Montrose — Houston's most culturally vibrant neighborhood. The company has been operating since 2019, generates approximately one million dollars in annual revenue, and maintains a near-5.0 Google rating. Texas DSHS licensed. Every product, every formula, every piece of artwork and packaging is created in-house in Houston.
Colin brings Houston grit, McAllen roots, and a builder's mindset to the company. Doctors use the formulas for Crohn's disease, IBS, ulcerative colitis, PTSD, benzo addiction, and insomnia. Custom creations are available for vegans, diabetics, and anyone with specific health needs. But the posture stays simple: make products with intent, answer directly, and never pretend cannabis is right for everyone.
7 ABC13 Features. 4 Years. 5 Reporters.
When Houston's #1 news source needs a cannabis expert, they call Colin. This is recognition that cannot be purchased — it can only be earned.
Reporter Tom Abrahams. The first ABC13 feature — and the origin of OilWell's foundational philosophy. Colin appears as "OilWell CBD, a local wholesaler," educating Houston about the newly legal CBD market following HB 1325.
Reporter Tom Abrahams returns. Colin featured as an ecosystem builder helping other entrepreneurs like Jonathan Pina enter the legal cannabis space, timed with Schumer-Booker-Wyden decriminalization push.
Reporter Steve Campion. An investigative feature that became one of ABC13's most referenced cannabis segments. Colin's radical honesty on mainstream television — with the expletive preserved by the network.
Colin: "I don't give a sh** if it's wrong to say you'll get high off it. Maybe you want to get high."
KTRK Staff. OilWell donated 1,000 special edition caviar pre-rolls — approximately $35,000 in product — to encourage COVID-19 vaccination. Partnership with The Game. Coordination with the City of Houston. No political strings.
Reporter Shelley Childers. When DSHS classified Delta-8 as Schedule I overnight, Colin had already removed all products from his shelves — proactively, before enforcement. Then he warned other operators who were unknowingly shipping Schedule I narcotics.
Reporter Nick Natario. Colin revealed to have a personal marijuana conviction. The article also debuted OilWell's CBD vending machine. The personal conviction history transforms every prior feature — every quote about education, about not selling snake oil, carries weight when you know this.
Reporter Nick Natario. Colin growing hemp on camera, framing the present moment as a "Renaissance." With Texas having only 10,000 active medical cannabis patients compared to Florida's 700,000, the untapped demand is massive.
The Science Behind Every Compound
Fourteen active compounds. Honest evidence tiers. Every claim cited. Where research gaps exist, we name them — because that's how trust actually works.
What it is: The non-intoxicating cannabinoid with the most rigorous clinical testing. CBD won't make you high, and it's the active ingredient in Epidiolex, the FDA-approved seizure medication.
What the Research Shows
CBD's strongest evidence comes from seizure disorders. The FDA approval for Epidiolex was based on robust clinical trials showing CBD reduces seizure frequency in rare epilepsy forms like Dravet syndrome [1][2]. A 2024 meta-analysis of anxiety studies pooled data from 316 participants and found a statistically significant anxiolytic signal — meaning CBD showed measurable anxiety-reducing effects [3]. For pain, a 2024 systematic review concluded the evidence is "promising but heterogeneous," with trial quality issues limiting how confident we can be [4]. Sleep research is weaker: a 2023 review on CBD and insomnia noted the underlying literature is "methodologically weak" overall [5].
What the Research Doesn't Show
CBD isn't a universal cure-all despite online marketing. The anxiety benefit, while real, was studied in limited clinical samples — not everyone responds equally. Sleep evidence is notably thin relative to market demand. Important safety signals include liver enzyme elevation in some users [6], potential drug interactions (CBD inhibits cytochrome P450), and GI side effects [1]. The strongest evidence is concentrated in specific indications (seizures, anxiety), not broad "wellness" claims.
Why It's in OilWell's RSO
We include 4,500mg of CBD because it's the most evidence-developed nonintoxicating cannabinoid, and research suggests it may modulate the effects of other compounds in the formula — including THC's intensity. For Houston residents seeking therapeutic benefit with minimal intoxication risk, CBD provides a research-backed foundation.
What it is: The "mother cannabinoid" — the acidic precursor that your cannabis plant converts into THC, CBD, and other cannabinoids as it matures. Pharmacologically distinct from both THC and CBD.
What the Research Shows
CBG acts on multiple receptor systems: cannabinoid receptors (CB1/CB2), alpha-2 adrenoceptors, and the serotonin 5-HT1A receptor [7]. Laboratory studies suggest it may be relevant to neurologic disorders, inflammatory bowel disease, and antibacterial activity — but these remain mostly preclinical findings [7][8]. The first human clinical trial for CBG, conducted at Washington State University in 2024, tested 20mg in a placebo-controlled design. Results showed CBG significantly reduced anxiety at 20, 45, and 60 minutes post-administration — a promising signal, though the sample size was small.
What the Research Doesn't Show
CBG's human clinical evidence is minimal relative to market availability. It's already being sold commercially in products nationwide, which is unusual — normally, companies wait for more human data. We don't yet know optimal dosing, long-term safety profiles, or how CBG interacts with other cannabinoids over weeks or months of use [7].
Why It's in OilWell's RSO
We include 3,000mg of CBG because early human evidence is encouraging, and laboratory work suggests unique pharmacologic properties that complement CBD and THC. It's one of the compounds most likely to benefit from the "entourage effect" — meaning it may work better as part of the full-spectrum formula than in isolation.
What it is: Structurally similar to delta-9 THC but binds to receptors with lower affinity, making it roughly 50-70% as potent. It's psychoactive — you will feel it — but typically produces a calmer, less intense effect than delta-9.
What the Research Shows
Delta-8 is a partial CB1 agonist, meaning it activates your cannabinoid receptors but less aggressively than delta-9 [9]. A 2023 scoping review examining evidence for delta-8 found that the literature is dominated by animal studies and product chemistry analysis rather than robust human clinical trials [10]. What human data exists suggests anxiolytic and anti-nausea effects similar to delta-9 but with a lower intensity profile. Delta-8 is also more chemically stable than delta-9 and easier to synthesize, which is why it's become commercially popular — but this manufacturing ease creates quality control challenges [11].
What the Research Doesn't Show
We lack long-term human safety studies specific to delta-8. The psychoactive mechanism is real — delta-8 should be treated as a genuine THC analogue — but its safety profile remains incompletely characterized. Manufacturing concerns exist: delta-8 can be a byproduct of delta-9 processing or synthesized from CBD, and testing standards vary dramatically across suppliers [10][11].
Why It's in OilWell's RSO
Delta-8 makes up 6,000mg of our formula because it provides therapeutic effect while maintaining a lower intensity profile than traditional RSO products. For Houston residents who want the benefits of THC but prefer a gentler experience — or who are sensitive to delta-9 at high doses — delta-8 offers a middle ground. We include it at transparent levels so you know exactly what you're getting.
What it is: The raw, acidic form of THC found in fresh cannabis plants. In its acid form, it does not produce intoxication — you could eat raw cannabis flower and not get high. Heat converts THCa into psychoactive THC through decarboxylation.
What the Research Shows
In laboratory and animal studies, THCa shows promise in several areas: anti-inflammatory effects through COX-2 inhibition, immunomodulatory signaling, neuroprotective activity via PPARγ agonism, and even antineoplastic potential in preclinical models [12]. These are credible mechanistic pathways, but translation to human efficacy remains incomplete. The critical caveat is that interpretation of THCa's effects depends heavily on preparation method, temperature exposure, storage conditions, and how the compound is delivered — all of which affect conversion to THC.
What the Research Doesn't Show
Human clinical trials demonstrating THCa efficacy are essentially absent. We don't know optimal dosing, whether the acid form itself provides benefit beyond what THC offers, or how stability and conversion affect real-world therapeutic outcomes. Chemically, 1mg of THCa converts to approximately 0.877mg of delta-9 THC after full decarboxylation [12].
Why It's in OilWell's RSO
We include 1,500mg of THCa because emerging laboratory evidence suggests unique anti-inflammatory and neuroprotective mechanisms distinct from THC itself. In our RSO formula, THCa provides both raw phytochemical diversity and partial conversion potential — giving you multiple active forms working together. The customer controls activation.
What it is: The classic "high" cannabinoid — the one that produces intoxication. Also one of the best-studied cannabis compounds in clinical research, with FDA approval for chemo-related nausea and HIV/AIDS-related appetite loss.
What the Research Shows
Delta-9 has the strongest clinical evidence for specific indications: chemotherapy-induced nausea and vomiting, appetite stimulation in HIV/AIDS wasting syndrome, and pain relief in some neuropathic and cancer pain settings [1]. A 2022 chronic pain review found that high-THC products may provide short-term pain benefit, though they're associated with increased dizziness, sedation, and nausea in some users [13]. A 2025 review highlighted important risk signals: high-concentration THC is associated with psychosis and schizophrenia risk in vulnerable populations, cannabis use disorder, and anxiety/depression outcomes in some users [15].
What the Research Doesn't Show
THC isn't right for everyone, and high doses carry real psychiatric risks. Traditional RSO products often contain 600-900mg of THC daily — a dose range associated with greater adverse effects. Individual vulnerability (genetics, age, concurrent mental health conditions) significantly influences outcomes.
Why It's in OilWell's RSO
OilWell's RSO includes only 90mg of delta-9 THC — dramatically lower than traditional RSO formulas — because we believe Houston residents deserve therapeutic benefit with substantially reduced intoxication and risk. We pair this conservative dose with high CBD and other non-intoxicating cannabinoids, creating a formula where the synergy works for you, not against you.
What it is: A cannabinoid formed when THC oxidizes — you'll find it in aged cannabis. Heavily marketed for sleep, but the clinical reality is far less impressive than the marketing suggests.
What the Research Shows
CBN is a CB1 receptor agonist with particular affinity for CB2 receptors and involvement in sleep signaling pathways. A 2021 narrative review screened 99 abstracts on CBN and sleep, ultimately reviewing only 8 articles — and found zero clinical trials using validated sleep measures [16]. A 2024 cannabis and sleep review concluded that overall cannabinoid sleep research doesn't match the scale of real-world use and marketing claims [17]. Rodent studies do show sleep promotion through CB1R activation, but rodents and humans have different sleep architecture.
What the Research Doesn't Show
Clinical efficacy for sleep in humans is essentially unproven despite widespread commercial availability. CBN is one of the clearest examples in cannabis science where cultural reputation and market saturation have vastly outpaced actual evidence [16][17]. We don't have optimal dosing data, long-term safety profiles, or reliable prediction of who will respond.
Why It's in OilWell's RSO
We include 750mg of CBN because emerging mechanisms through CB1R activation are credible. However, we're honest: the science here is thin. If you find CBN helpful, that's valuable — but we want you to know you're relying on emerging mechanisms, not established clinical proof. Transparency builds trust.
What it is: A minor cannabinoid with distinct pharmacodynamics — meaning it interacts with your body through pathways different from CBD or THC. Scientifically credible but very early in clinical investigation.
What the Research Shows
A 2024 review identified CBC as having antinociceptive (pain-blocking), antibacterial, and anti-seizure potential in preclinical models [18]. Older laboratory literature points to anti-inflammatory effects, reduced gut hypermobility, and modest analgesic activity in rodent pain models [19]. These are mechanistically reasonable findings that make CBC worthy of human investigation — but no clinical trials have yet proven efficacy in people.
What the Research Doesn't Show
Clinical efficacy, optimal dosing, safety profiles, and drug interactions are essentially unknown. Like CBG, CBC is already sold OTC in many places despite the evidence base remaining extremely limited [18].
Why It's in OilWell's RSO
We include 750mg of CBC as part of our full-spectrum approach because the early mechanistic science is credible and suggests it may contribute to pain and inflammatory benefit. CBC represents the frontier of cannabinoid research — promising, but honest about its limitations. It's the kind of compound that works best in combination, not isolation.
Also found in: Lemon peels, oranges, rosemary
What the Research Shows
Limonene demonstrates antioxidant, anti-inflammatory, and gastroprotective signals in laboratory studies — but most literature comes from non-human models or non-cannabis plants [21]. A promising 2024 Drexel University study directly tested limonene + THC in humans and found a measurable anxiety-reducing entourage effect, suggesting limonene may modulate how THC is perceived and processed [24]. This is one of the few human clinical studies of a terpene-cannabinoid interaction.
What the Research Doesn't Show
We lack human trials isolating limonene alone from cannabis or establishing optimal dosing. Important caveat: limonene can oxidize over time and storage, forming contact allergens [22] — which is why fresh, properly stored products matter.
Why It's in OilWell's RSO
Limonene is preserved in our live terpene profile because the Drexel entourage effect study suggests it may work synergistically with our THC and CBD. The citrus profile is also what Houston residents expect from quality cannabis — a sign of freshness and proper preservation.
Also found in: Mango, hops, thyme
What the Research Shows
A 2021 review examined myrcene's pharmacology and identified anxiolytic, antioxidant, anti-inflammatory, and analgesic mechanisms in preclinical models [23]. These are credible signals. However, the review explicitly states that human studies are lacking — meaning the evidence is laboratory-based, not clinically proven in people.
What the Research Doesn't Show
The popular claim that myrcene is responsible for "couch lock" (heavy, sedating cannabis effects) is stronger than evidence supports [20][23]. Isolating its role in subjective effects requires controlled human trials — which don't yet exist.
Why It's in OilWell's RSO
Myrcene is naturally present in our live terpene profile because it appears in most cannabis strains and carries promising early mechanistic signals. We include it not because we claim it produces sedation, but because emerging evidence suggests it supports the anxiolytic and pain-modulating profile we're aiming for.
Also found in: Black pepper, cloves, hops
What the Research Shows
Beta-caryophyllene is the most mechanistically interesting terpene because it directly binds to CB2 receptors — part of your endocannabinoid system — which are involved in immune and inflammatory signaling [24]. Laboratory research indicates anti-inflammatory, immunomodulatory, and neuroprotective effects. The fact that it's a functional cannabinoid receptor agonist (not just a flavor) suggests real pharmacologic potential.
What the Research Doesn't Show
While the CB2 mechanism is established, we lack robust human clinical trials proving that beta-caryophyllene at cannabis concentrations provides measurable therapeutic benefit [24]. The synergy with THC and CBD in a whole-plant product is theoretically sound but not clinically proven.
Why It's in OilWell's RSO
Beta-caryophyllene is the terpene most likely to have real pharmacologic significance in our formula because of its CB2 agonism. If the entourage effect is real for any terpene, caryophyllene is the leading candidate. Houston residents seeking immune and inflammatory support benefit from a terpene that isn't just aromatic — it's functionally active.
Also found in: Pine trees, rosemary, basil
What the Research Shows
A 2021 brain-health review examined pinene and identified antioxidant, anti-inflammatory, and neuroprotective signals — but noted these findings are mostly preclinical [25]. A 2021 University of Arizona study found that cannabis terpenes, including pinene, provided measurable pain relief independently of cannabinoids in human subjects [25]. Claims that pinene counterbalances THC's psychoactive effects or enhances memory remain interesting hypotheses rather than settled facts.
What the Research Doesn't Show
Controlled human studies isolating pinene's effects on cognition or attention are absent. The memory-enhancing "nootropic" marketing claim exceeds current evidence. We don't know optimal dosing or how pinene's effects vary with the rest of the formula.
Why It's in OilWell's RSO
Pinene is preserved in our live terpene profile because emerging evidence suggests direct analgesic effects independent of cannabinoids, and its neuroprotective potential aligns with our pain and cognitive support goals.
Also found in: Lavender, mint, some cannabis strains
What the Research Shows
Linalool has recognized pharmacology in stress, mood, and brain health — particularly in preclinical models [25][26]. Some research suggests possible antidepressant mechanisms through GABA signaling and serotonin modulation [26]. The lavender-anxiety link, while widely recognized, lacks robust controlled trials in cannabis contexts specifically.
What the Research Doesn't Show
Human clinical trials proving linalool efficacy from cannabis are absent. Additionally, linalool is volatile and can oxidize during storage, forming hydroperoxides that are contact allergens [22] — meaning storage quality directly affects safety and efficacy.
Why It's in OilWell's RSO
We preserve linalool in our live terpene profile because its stress and mood pharmacology aligns with our formula's anxiolytic goals, and it complements CBD's documented anxiety benefits.
Also found in: Hops, cloves, sage
What the Research Shows
A 2024 scoping review examined humulene across 340 articles and found broad preclinical anti-inflammatory evidence [27]. Some rodent work suggests humulene may have cannabimimetic properties — meaning it might interact with your cannabinoid system — through CB1 and adenosine A2a signaling [27].
What the Research Doesn't Show
Human clinical efficacy is far from established. The cannabimimetic hypothesis is intriguing but unproven in humans. We don't have dosing data, safety profiles, or confirmation that humulene at cannabis concentrations provides meaningful therapeutic benefit [27].
Why It's in OilWell's RSO
Humulene is naturally present in our live terpene profile and retained because emerging evidence suggests it may amplify the anti-inflammatory profile through both direct effects and cannabinoid-system interaction.

What the Research Shows
A 2021 systematic review screened 2,449 records on terpinolene and reviewed 57 studies, finding a range of potential biological effects [28]. However, the research is dominated by computer modeling, test tubes, and animal studies — not human trials. Plausible mechanisms, minimal clinical proof.
What the Research Doesn't Show
Human efficacy, dosing, and safety are essentially unknown. Terpinolene is included in cannabis products based more on historical use and preliminary mechanistic promise than on clinical data [28].
Why It's in OilWell's RSO
Terpinolene appears naturally in our live terpene profile as part of preserving full-spectrum complexity. While its clinical significance is early-stage, including it maintains the plant's natural chemical diversity — the foundation of the entourage effect hypothesis. We're honest about what we don't know while preserving the whole-plant profile Houston residents expect.
Who Is Rick Simpson?
The man who gave his oil away for free — and changed cannabis medicine forever. Understanding Rick Simpson isn't marketing. It's context for why OilWell does what it does.
Rick Simpson was a Canadian power engineer working in a hospital in Nova Scotia when he was diagnosed with basal cell carcinoma — a form of skin cancer — in 2003. After hearing about a 1975 study from the Journal of the National Cancer Institute showing THC killed cancer cells in mice, Simpson decided to try applying concentrated cannabis oil directly to his cancerous skin lesions.
According to Simpson's account, the lesions disappeared within days. His physician confirmed the cancer was gone but reportedly refused to acknowledge the cannabis oil as a factor. This experience became the foundation of everything that followed: a man who believed he had cured his own cancer with cannabis oil, and a medical establishment that refused to investigate the possibility.
It's critical to understand what this is and what it isn't. Simpson's experience is a single case report — not a clinical trial, not a controlled study, not scientific proof. But it was real to him, and it launched a movement that changed how millions of people think about cannabis as medicine.
Rick Simpson Oil — the original — is a full-plant extract made by soaking cannabis flower in a solvent (typically naphtha or isopropyl alcohol), then boiling off the solvent to leave behind a thick, dark, tar-like concentrate. The original RSO was extremely high in THC — often 60-90% — because Simpson used high-THC indica strains and the extraction process concentrated everything.
Simpson's recommended protocol was aggressive: work up to consuming one gram (approximately 600-900mg of THC) per day over 90 days. For context, a standard cannabis edible in a legal market contains 5-10mg of THC. Simpson was recommending 60-180 times that amount daily. The side effects were significant — extreme sedation, impairment, tolerance development — but Simpson considered these acceptable trade-offs for what he believed was a cancer treatment.
The key point is that Simpson never patented his oil or tried to profit from it. He published his recipe freely, taught people how to make it themselves, and traveled internationally advocating for cannabis medicine. He gave the oil away. That ethos — the belief that medicine should be shared, not hoarded — is the philosophical foundation OilWell was built on.
This is the most important question, and the honest answer is: we don't know yet, and anyone who claims certainty is lying to you.
Here's what we do know. The National Cancer Institute (NCI) acknowledges that cannabinoids can cause cell death in laboratory conditions, may block blood vessel growth that tumors need, and show anti-inflammatory and antiviral properties in preclinical research. Multiple peer-reviewed studies have demonstrated that THC and CBD can induce apoptosis (programmed cell death) in cancer cell lines. A 2014 study in Molecular Cancer Therapeutics found that combined THC and CBD enhanced radiation treatment effectiveness in glioma models.
Here's what we don't know. No human clinical trial has proven that RSO or any cannabis product cures cancer. Cell lines and animal models do not reliably predict human outcomes. The doses used in preclinical research don't always translate to achievable human doses. Individual cancers are biologically diverse — what kills one cancer cell line in a petri dish may do nothing to another.
OilWell's position is clear: RSO education complements medical care; it does not replace it. If you are a cancer patient, please work with your oncology team. Consider RSO as a potential supportive option — not an alternative to proven treatment. We will never tell you to replace chemotherapy with cannabis oil. Rick Simpson believed deeply in his oil. We believe deeply in honest education about what the science actually shows.
Traditional RSO and OilWell's RSO share a philosophy but differ dramatically in formulation. Understanding the differences matters because it explains why we built this product the way we did.
Traditional RSO uses whole-plant solvent extraction, producing a single dark concentrate that's heavy on THC and whatever else the plant contained. There's no standardization — each batch is different depending on the strain, growing conditions, and extraction technique. The THC content is extremely high (600-900mg daily under Simpson's protocol), and the experience is correspondingly intense.
OilWell's RSO uses individual cannabinoid distillates and isolates — each lab-tested and verified for purity — blended in precise ratios with organic MCT oil as a carrier. Seven cannabinoids at specific milligram amounts. Seven live terpenes at 5%. Zero extraction solvents. The delta-9 THC content is 90mg total — 85-90% lower than traditional RSO — because we believe you can get therapeutic benefit without the overwhelming sedation Simpson's protocol required.
We didn't reinvent RSO to disrespect it. We evolved it because the science has evolved. Multi-cannabinoid formulation, terpene preservation, standardized dosing, and third-party testing didn't exist when Rick Simpson was applying oil to his skin in 2003. They exist now. We use them because Houston deserves the most advanced version of what Simpson started — built on his open-source ethos, refined with modern science.
Regardless of where the cancer science eventually lands, Rick Simpson got several things profoundly right, and they shaped OilWell's DNA.
He gave it away. Simpson never patented RSO. He published the recipe, taught people how to make it, and traveled the world advocating. Colin published the CBD golden paste recipe that helped Bentley. OilWell publishes the full RSO formula on this page. The ethos is the same: medicine should be shared.
He insisted on full-spectrum. Simpson understood intuitively what the entourage effect hypothesis would later articulate scientifically — that the whole plant works differently than isolated compounds. OilWell's 7-cannabinoid, 7-terpene formula is the modern expression of that same principle.
He challenged the system. Simpson faced prosecution in Canada, had his home raided, and was forced to leave the country. He kept going anyway. Colin has a marijuana conviction on his record and still built a cannabis company in Texas. Different eras, same refusal to stop.
He prioritized patients over profit. Simpson's entire movement was about access — getting medicine to people who needed it, regardless of ability to pay. OilWell's open-source formula, transparent pricing, and educational approach come directly from that philosophy.
Rick Simpson didn't build OilWell. But OilWell wouldn't exist without what he started. This page exists to honor that — with honesty, not mythology.

Frequently Asked Questions
Yes. OilWell's RSO contains less than 0.3% delta-9 THC by dry weight, making it fully compliant with the 2018 Farm Bill. All cannabinoids are hemp-derived. The product is legal under federal law and ships to all 50 states. THCa — which is non-psychoactive in its acid form — is not delta-9 THC and does not count toward the 0.3% threshold at point of sale. If you choose to decarboxylate (heat) the oil at home, that decision and its legal implications are yours. We ship with full documentation, Certificates of Analysis, and receipts.
If you use the oil raw (no heat), the THCa stays in its acid form and is non-psychoactive. However, standard drug tests may still detect cannabinoid metabolites. Delta-8 THC and any activated THCa (via decarboxylation or vaping) will trigger a standard THC drug test. We're honest about this: if your employment requires drug testing, cannabinoid products carry detection risk. Plan accordingly.
Standard CBD oil typically contains one or two cannabinoids — usually CBD with trace amounts of others. OilWell's RSO contains seven distinct cannabinoids (CBD, CBG, Delta-8 THC, THCa, Delta-9 THC, CBN, CBC) totaling 16,590mg, plus seven live terpenes at 5%. The multi-cannabinoid approach reflects the entourage effect hypothesis — that cannabinoids and terpenes work more effectively together than in isolation. This is a full-spectrum, clinical-strength formulation, not a single-compound wellness product.
No cannabis product has been proven to cure cancer in human clinical trials. Preclinical research (cell lines and animal models) shows that THC and CBD can induce apoptosis and inhibit proliferation in certain cancer cells, but these findings have not translated into proven human cancer cures. The NCI acknowledges this research without endorsing cannabis as cancer treatment. The FDA has not approved any cannabis plant product for cancer. We take this seriously: RSO education complements medical care; it does not replace it. If you are a cancer patient, please work with your oncology team and consider RSO as a potential supportive option — not an alternative to proven treatment.
Every batch undergoes third-party lab testing covering potency (HPLC/UHPLC, ±2% accuracy), heavy metals (ICP-MS for arsenic, cadmium, lead, mercury), pesticides (400+ compounds via LC-MS/MS and GC-MS/MS), residual solvents (headspace GC), and microbial contaminants (E. coli, Salmonella, Aspergillus). Certificates of Analysis are available on request and through our website. OilWell is Texas DSHS licensed and uses zero extraction solvents — the product is formulated from individual distillates and isolates blended in organic MCT oil.
Because Rick Simpson gave his oil away for free and taught people how to make it. We respect that ethos. If you can't afford $129.99, you can see every cannabinoid, every milligram, every percentage in our formula — source the ingredients and make your own. We sell a professionally manufactured, lab-tested, standardized version for those who want it. We publish the recipe for those who need it. That's not a marketing strategy — it's the foundational behavior of this company, going back to the day Colin published the CBD golden paste recipe that saved Bentley's life.
We ship to all 50 US states where Farm Bill-compliant products are legal via USPS Priority Mail, FedEx, and UPS. Discreet packaging, tracking on all orders. Internationally, we've delivered to multiple countries across multiple continents — all packages include COAs and full documentation for customs. The customer is responsible for verifying legality in their jurisdiction. Contact us at (832) 416-2816 or [email protected] for international shipping quotes.
Start low, go slow. Begin with 0.25 mL of the sublingual oil (that's about a quarter of the dropper) and assess effects over 2-3 hours before considering more. If you want to avoid any psychoactive effect, use the oil raw — the THCa stays non-psychoactive and you get anti-inflammatory cannabinoid exposure without impairment. For your first time, try it at home in the evening when you have no obligations. Individual responses vary based on body weight, metabolism, tolerance, and concurrent medications. And always — consult a healthcare provider if you have medical conditions or take medications.
