Rick Simpson Oil: Introduction
Rick Simpson Oil (RSO), a cannabis extract rich in THC, has surged in popularity across Canada for its purported health benefits. Originally crafted by Rick Simpson to treat his skin cancer, RSO is now widely explored for pain relief, mental health support, and more. This guide dives into its history, science, legal status in Canada, and practical tips for safe use.
What is Rick Simpson Oil?
History & Origin
In 2003, Canadian engineer Rick Simpson developed RSO after using cannabis oil to treat his basal cell carcinoma. His anecdotal success story spread, positioning RSO as a controversial alternative therapy.
RSO vs. CBD Oil: Key Differences

- THC Content: RSO contains up to 90% THC, offering psychoactive effects, while CBD oil is non-intoxicating.
- Usage: RSO is often used in small doses for chronic conditions; CBD oil targets anxiety and inflammation without a “high.”
Top 5 Benefits of Rick Simpson Oil
Cancer Treatment: What Research Says
- A 2013 study in Molecular Cancer Therapeutics found THC and CBD may inhibit brain cancer cell growth. However, Health Canada warns RSO is not an approved cancer treatment.
- Key Takeaway: Anecdotal evidence exists, but clinical trials are limited.
Pain & Chronic Illness Relief
- The National Institute on Drug Abuse acknowledges cannabis’s efficacy in chronic pain management. RSO’s high THC content may enhance these effects.
Mental Health Support
- Caution: While low THC doses may reduce anxiety, excessive amounts can worsen symptoms. A 2017 review in Clinical Psychology Review highlights this dual effect.
Anti-Inflammatory & Neuroprotective Properties
Research highlights THC and CBD’s potential to reduce inflammation, a root cause of diseases like arthritis and Alzheimer’s.
- A 2020 study in Cannabis and Cannabinoid Research found THC modulates immune responses, potentially easing autoimmune conditions.
- Neuroprotection: Preclinical trials suggest cannabinoids protect brain cells from oxidative stress, offering hope for Parkinson’s and multiple sclerosis.
Skin Health & Topical Applications
RSO’s original use for skin cancer has spurred interest in its topical benefits:
- Psoriasis & Eczema: Anecdotal reports suggest RSO reduces redness and itching. A 2018 Journal of Dermatological Science study noted CBD’s anti-inflammatory effects on skin cells.
- Acne: THC’s antibacterial properties may combat acne-causing bacteria, though clinical evidence is limited.
How to Make Rick Simpson Oil (DIY Guide)?

- Ingredients: 1 lb cannabis flower, high-proof solvent (e.g., ethanol).
- Steps: Soak cannabis in solvent, strain, and evaporate to create a thick oil.
- Safety: Avoid open flames due to flammable solvents.
Note: Home production is illegal in Canada. This guide is for informational/Educational purposes only.
How to Use Rick Simpson Oil Safely?
Dosage & Application
- Start Low: 0.1 mL daily, gradually increasing to avoid psychoactive overload.
- Methods: Sublingual drops, capsules, or topical creams.
Tailoring RSO use to individual needs can optimize results:
- Chronic Pain: Start with 0.1 mL daily, increasing by 0.05 mL every 3 days. Monitor pain levels and adjust with medical guidance.
- Sleep Disorders: Microdoses (0.05 mL) 1 hour before bedtime may improve sleep latency.
Drug Interactions & Contraindications
- Blood Thinners (e.g., Warfarin): THC may enhance bleeding risk.
- Antidepressants: Combined use with SSRIs could amplify drowsiness or agitation.
- Consultation Required: Always discuss RSO use with a pharmacist or physician to avoid adverse interactions.
