What Is FECO Oil (Full Extract Cannabis Oil)?
FECO stands for Full Extract Cannabis Oil. Like RSO (Rick Simpson Oil), FECO is a whole-plant cannabis extract containing the full spectrum of cannabinoids, terpenes, and other beneficial compounds.
The key difference between FECO and RSO is the extraction solvent. FECO is typically made with food-grade ethanol (like Everclear), which many consider safer for consumption than other solvents. This results in a slightly cleaner product with less chlorophyll and a smoother taste.
FECO vs RSO: Key Differences
| Feature | FECO | RSO |
|---|---|---|
| Extraction Solvent | Food-grade ethanol (Everclear) | Various solvents (historically naphtha) |
| Chlorophyll Content | Lower (cleaner) | Higher (more plant matter) |
| Taste | Smoother | More intense/earthy |
| Potency | High (60-95% THC) | High (60-95% THC) |
Materials Needed for FECO Extraction
- High-quality cannabis flower or trim (28-30 grams for a small batch)
- Food-grade 190-proof ethanol (Everclear or similar) - Never use denatured alcohol
- Large glass mason jars with lids
- Double boiler or rice cooker for safe evaporation
- Cheesecloth and coffee filters
- Silicone spatula or wooden spoon
- Syringes for storage
- Dark glass containers for long-term storage
- Safety equipment: Gloves, safety glasses, fire extinguisher
- Strong ventilation or outdoor setup
Safety Precautions for FECO Extraction
- Work outdoors or in extremely well-ventilated areas
- No open flames, sparks, or heat sources nearby - ethanol is highly flammable
- Use only food-grade ethanol - never denatured alcohol or rubbing alcohol
- Wear safety gloves and eye protection
- Have a fire extinguisher rated for alcohol fires accessible
- Never leave evaporation unattended
Step-by-Step Guide: How to Make FECO Oil
Step 1: Decarboxylation
Before extraction, cannabis must be decarboxylated to activate cannabinoids. Grind your cannabis coarsely and spread on a baking sheet. Bake at 220-240°F (105-115°C) for 30-45 minutes, stirring halfway through. Let cool completely.
Step 2: First Ethanol Wash (Quick Wash)
Place decarbed cannabis in a glass jar. Pour enough chilled ethanol to cover the material by 1-2 inches. Stir gently for 3-5 minutes. The liquid will turn green/golden as it extracts cannabinoids.
Tip: Chilling both the cannabis and ethanol beforehand (freezer for 24 hours) helps reduce chlorophyll extraction for a cleaner FECO.
Step 3: Strain and Filter
Strain the liquid through cheesecloth, squeezing to extract as much liquid as possible. Filter again through coffee filters for maximum clarity. You can do a second quick wash with fresh ethanol for additional extraction.
Step 4: Evaporate Ethanol
Pour the filtered tincture into a double boiler or rice cooker (no more than half full). Heat gently with excellent ventilation. The ethanol will slowly evaporate over 4-8+ hours.
Critical: Keep temperatures below 250°F (121°C) to preserve cannabinoids. Never use open flame. Monitor continuously and stir occasionally.
Step 5: Final Processing and Storage
When the FECO is thick, dark, and no longer smells of alcohol, it is ready. Transfer while warm to syringes or dark glass containers. Store in a cool, dark place or refrigerate for extended shelf life.
Expected Yield: 3-8 grams of FECO from 1 ounce of quality cannabis.
How to Test for Residual Solvent
Properly made FECO should have minimal alcohol smell or taste. To test:
- Smell the finished product - no strong alcohol odor should remain
- The consistency should be thick and tar-like, not runny
- When gently warmed, no bubbles should form (bubbles indicate remaining solvent)
Safe FECO Dosing Guidelines
FECO is extremely potent. Follow the safe FECO dosing guide:
- Start with a rice-grain sized dose (approximately 0.025-0.05g)
- Wait several hours before taking more
- Gradually increase over weeks as tolerance builds
- Effects can last 6-8+ hours

The Economics and Safety of Commercial FECO
Professional FECO production involves pharmaceutical-grade equipment, rigorous quality control, and stringent safety protocols that cannot be replicated in home environments. Commercial manufacturers use closed-loop extraction systems that contain ethanol vapors, preventing environmental exposure and fire hazards. These systems cost tens of thousands of dollars and require specialized expertise to operate safely.
Beyond equipment costs, commercial FECO production requires regulatory compliance, liability insurance, and adherence to local health codes. These overhead expenses ensure consumers receive a safe, consistently potent product. Laboratory testing adds significant cost but provides absolute certainty about what you're consuming—testing for potency, microbial contamination, pesticide residues, heavy metals, and solvent residue.
When calculated per-dose, commercial FECO is often more cost-effective than home extraction despite higher upfront costs. Home extraction can produce unpredictable results—one batch might yield 5 grams of 70% FECO, another might yield 3 grams of 50% FECO from identical starting material. This inconsistency wastes money and creates dosing uncertainty. Professional production maintains consistency batch after batch.

Frequently Asked Questions About Making FECO
Q: What is the difference between FECO and RSO extraction?
FECO is typically made using food-grade ethanol (like Everclear), resulting in a cleaner product. RSO traditionally uses other solvents. Both are full-spectrum extracts, but FECO often has less chlorophyll and a smoother taste.
Q: How do I know when all the alcohol has evaporated from FECO?
The FECO is ready when it no longer smells of alcohol, has a thick tar-like consistency, and no bubbles form when gently warmed.
Q: Can I make FECO with CBD flower?
Yes, FECO can be made from CBD-dominant hemp flower to create CBD FECO with minimal THC. The extraction process is identical - only the starting material differs.
Q: Is homemade FECO as potent as commercial products?
Homemade FECO potency varies significantly based on starting material, extraction efficiency, and technique. Commercial lab-tested FECO provides consistent, verified potency that home extraction cannot match.
Why FECO Is Considered an Upgrade Over Traditional RSO
FECO represents an evolution in cannabis concentrate production. While RSO pioneered full-spectrum extracts, FECO improves on several key aspects:
Better Taste Profile
FECO's smoother, more refined taste comes from careful ethanol selection and controlled evaporation, removing excess chlorophyll that RSO retains. Many users find FECO significantly more palatable.
Improved Consistency
FECO production uses standardized processes, resulting in more consistent batch-to-batch potency and texture. This makes dosing more predictable and reliable.
Enhanced Purity
Modern FECO production standards emphasize purity testing, solvent residue removal, and microbial screening—standards not always applied to traditional RSO.
Full-Spectrum Preservation
While maintaining the full-spectrum benefits of RSO, FECO uses techniques that better preserve delicate terpenes and cannabinoids, enhancing the entourage effect.
The Importance of Third-Party Laboratory Testing
For any cannabis concentrate including FECO, laboratory testing is absolutely critical. Here's what responsible manufacturers test for:
Safety Testing
- •Microbial (E. coli, Salmonella, mold, yeast)
- •Pesticide residues
- •Heavy metals (lead, cadmium, arsenic)
- •Solvent residue
- •Moisture content
Potency Testing
- •THC content percentage
- •THCA (inactive form)
- •CBD content percentage
- •Other cannabinoids (CBG, CBC, etc.)
- •Terpene profile (qualitative)
Homemade FECO vs Lab-Tested Commercial FECO
While understanding FECO production is valuable, there are significant advantages to choosing commercially produced, lab-tested products:
| Aspect | Homemade FECO | Commercial FECO |
|---|---|---|
| Verified Potency | Unknown/Guesswork | Lab-tested and documented |
| Contamination Testing | No testing | Complete safety screening |
| Solvent Safety | Risk of residual ethanol | Tested solvent-free |
| Extraction Equipment | Home equipment (less precise) | Professional-grade equipment |
| Consistency | Batch variation | Standardized process |
| Dosing Accuracy | Difficult/Impossible | Easy and precise |
| Safety/Hazard Risk | High (fire, fumes) | Low (professional operation) |
| Legal Status | Often illegal | Legal from licensed retailers |
Different FECO Production Methods and Variations
Not all FECO is produced identically. Here are common variations in commercial FECO production:
Cold Ethanol Extraction
Cannabis is soaked in ethanol at cold temperatures (freezer). This preserves more delicate terpenes and cannabinoids. Results in a smoother, more flavorful product.
Warm Ethanol Extraction
Uses room-temperature or slightly warmed ethanol. Extracts more plant material quickly but may degrade some terpenes. Faster process than cold extraction.
Vacuum-Assisted Evaporation
Uses vacuum and low heat to remove solvent more gently. Results in better terpene retention and a superior final product. More expensive production method.
Different Solvent Choices
While ethanol is most common, some producers use food-grade ethanol grades (190-proof vs 151-proof), affecting final product characteristics.
FECO Cannabinoid Ratios: Understanding What You're Buying
Commercial FECO comes in various cannabinoid ratios depending on the source material and intended use:
High-THC FECO (70-90% THC)
Made from THC-dominant cannabis strains. Produces strong psychoactive effects. Best for experienced users seeking potent effects.
Balanced FECO (1:1 THC:CBD or similar)
Contains roughly equal THC and CBD. Provides balanced effects with reduced psychoactivity. Popular for therapeutic use.
High-CBD FECO (70-90% CBD)
Made from CBD-dominant strains or hemp. Non-intoxicating. Popular for pain relief, anxiety, and daily wellness use.
Full-Spectrum with Defined Ratios
Specific blends like 20:1 CBD:THC or custom ratios for specific therapeutic goals. Allows users to choose exactly what they need.
Proper Dosing of FECO: From Beginner to Experienced
Knowing how to dose FECO properly is essential for safe and effective use:
Complete Beginner
Start with 2-5mg THC (rice-grain size). Wait 2-4 hours to assess effects. Don't increase until you understand individual response. This conservative approach prevents negative experiences.
Beginner User
After initial tolerance building, increase to 5-15mg THC daily. Take consistently at the same time. Monitor effects and only increase if needed.
Intermediate User
Comfortable with 15-30mg THC per dose. May take 1-2 times daily. Can experiment with different consumption methods (sublingual vs swallowing).
Experienced/High-Tolerance User
May use 30-100mg+ THC daily. Should work with a healthcare provider to ensure appropriate use for their situation.
✓ Pro Tip: Using Your Lab Results for Accurate Dosing
The Certificate of Analysis provides exact mg/mL THC content. If a 1mL syringe contains 800mg total and is 80% THC, that's 640mg THC total. A rice-grain amount (roughly 0.1mL) would be approximately 64mg THC.
Understanding the Risks of Home FECO Extraction
While FECO extraction is often easier and potentially safer than traditional RSO (due to ethanol's properties), significant risks remain:
⚠️ Ethanol Vapor Exposure: While ethanol is less toxic than some solvents, its vapors are still harmful with prolonged exposure, causing dizziness, respiratory irritation, and neurological effects.
⚠️ Fire Hazard: Ethanol is flammable. Improper heat source or ignition source can cause fires or explosions, especially when evaporating large amounts.
⚠️ Unknown Potency: Without lab testing, you cannot know the actual THC content, making safe dosing impossible.
⚠️ Microbial Contamination: Without sterile techniques and testing, mold or bacterial growth is possible, creating health hazards.
⚠️ Legal Issues: In many jurisdictions, extraction remains illegal even where cannabis possession is legal, risking felony charges.
