Introduction
When researching cannabis extracts, you’ll likely come across two powerful options: FECO (Full Extract Cannabis Oil) and RSO (Rick Simpson Oil). They’re both thick, dark oils made from the entire cannabis plant — but they’re not the same.
In this blog, we’ll break down the key differences between FECO and RSO, how each is made, what they’re used for, and which one may be better for your needs.
What is FECO?
FECO stands for Full Extract Cannabis Oil. It’s made by extracting all beneficial compounds (cannabinoids, terpenes, flavonoids) from the cannabis plant using food-safe solvents like ethanol.
✅ Contains a broad cannabinoid profile
✅ Retains natural terpenes for the entourage effect
✅ UK legal if THC is under 0.2%
✅ Typically sold in syringes for oral use
💡 Best for: holistic wellness, inflammation, pain relief, and immune support.
What is RSO?
RSO stands for Rick Simpson Oil, named after the Canadian medical cannabis activist who popularized its use. It’s typically extracted using isopropyl alcohol or similar solvents and is known for its high THC concentration.
✅ Often used in cancer support protocols (especially in North America)
❌ Not legal in the UK due to high THC content
❌ Lacks the same quality control or lab testing in unregulated sources
💡 Best for: patients requiring high-THC cannabis oil under medical guidance (in legal markets).
FECO vs. RSO: Key Differences
Feature | FECO Oil | RSO (Rick Simpson Oil) |
---|---|---|
Legal in UK? | ✅ Yes (under 0.2% THC) | ❌ No (usually exceeds legal THC limit) |
THC Content | Low to trace (under legal limit) | High (up to 90% THC) |
Common Use | Natural wellness, pain, recovery | Cancer protocols, medical cannabis therapy |
Solvent Used | Food-grade ethanol or CO2 | Isopropyl alcohol or naphtha (riskier) |
Source | Lab-tested, compliant brands | Often homemade or black market |
Availability | UK + EU online stores | North American medical systems only |
Which One Should You Choose?
✅ Choose FECO if you’re in the UK or EU, looking for:
-
Safe, legal access to full-spectrum cannabis oil
-
Relief from anxiety, inflammation, or fatigue
-
Supportive daily wellness with trace THC
❌ Avoid RSO unless you're in a region where high-THC medical cannabis is legal — and only under the guidance of a healthcare professional.
Final Thoughts
While FECO and RSO may look similar, their legality, potency, and extraction methods differ dramatically. For UK residents seeking a safe, legal, and effective cannabis extract, FECO oil is the clear winner.
