What Is RSO Oil (Rick Simpson Oil)?
RSO oil, also known as Rick Simpson Oil, is a thick, dark, highly concentrated full-spectrum cannabis extract made from the whole plant. It contains a rich profile of cannabinoids (especially high THC levels), terpenes, and other natural compounds that work together through the entourage effect.
Many people search for how to make RSO, RSO extraction method, or make RSO at home because they want to learn the classic solvent-based technique popularized by Rick Simpson himself. The traditional method involves using solvents to extract cannabinoids, then evaporating the solvent to leave behind concentrated oil.
Materials Needed for the Traditional RSO Recipe
For a small batch (using about 1 ounce / 28 grams of cannabis), you will need:
- High-quality cannabis flower, trim, or shake (indica-dominant strains are traditional)
- Food-grade solvent: 99% isopropyl alcohol or Everclear (190-proof grain alcohol) — never use rubbing alcohol with additives
- Rice cooker (highly recommended for safe evaporation)
- Large glass bowls or mason jars
- Cheesecloth or fine strainer
- Wooden spoon or silicone spatula
- Coffee filters (for final straining)
- Fan for ventilation
- Thermometer (optional)
- Safety equipment: Gloves, safety glasses, and fire extinguisher
Safety First - Critical Precautions
- Work only in a well-ventilated outdoor area or garage with strong airflow
- Keep away from all flames, sparks, stoves, cigarettes, or pilot lights
- Alcohol vapors are extremely flammable and can explode
- Never leave the evaporation process unattended
- Have a fire extinguisher rated for chemical fires nearby
Step-by-Step Guide: How to Make RSO Oil
Step 1: Decarboxylation (Activate the THC)
Grind your cannabis material coarsely. Spread it on a baking sheet and bake at 220–240°F (105–115°C) for 30–45 minutes. This converts THCA into active THC. Stir halfway through. Let it cool completely.
Note: Some people skip this and let the heat from evaporation do the work, but pre-decarb gives more consistent potency.
Step 2: Soak the Cannabis in Solvent
Place the decarbed cannabis in a large glass bowl. Pour enough chilled solvent (Everclear or isopropyl) to fully cover the material (about 1–2 inches above). Stir and mash gently for 3–5 minutes. The solvent will turn dark green/brown as it pulls out cannabinoids.
For a cleaner extract, do a quick second wash with fresh solvent.
Step 3: Strain the Mixture
Pour the liquid through cheesecloth or a fine strainer into another container. Squeeze the plant material firmly to extract as much liquid as possible. Filter again with coffee filters for clarity.
Step 4: Evaporate the Solvent (Rice Cooker Method)
Pour the filtered tincture into your rice cooker (fill no more than halfway). Set the rice cooker to "Cook" or "Warm" mode. Keep the lid off and place a fan nearby for ventilation.
The alcohol will slowly evaporate. This can take 4–8+ hours depending on batch size. Never leave it unattended.
As the liquid reduces, you can add more tincture if needed. Stir occasionally. When only thick oil remains and no more alcohol smell is present, it is nearly done. The final temperature should stay below 250°F (121°C) to avoid degrading cannabinoids.
Step 5: Final Purification and Storage
Pour the hot oil into a small glass container. Let it cool and thicken into a dark, sticky tar-like consistency. Some people do a final gentle heat on low to remove any remaining solvent.
Store in a syringe or airtight glass jar in a cool, dark place. Properly made RSO can last months.
Yield: From 1 ounce of cannabis, you may get 3–8 grams of RSO depending on potency and efficiency.
Common Mistakes to Avoid
- Using the wrong solvent (avoid anything not food-grade)
- Poor ventilation → fire or health risk
- Overheating the oil → degraded cannabinoids and harsh taste
- Not straining well → plant particles in final oil
- Incorrect dosing later (RSO is extremely potent)
Safe RSO Dosing Guide
If you ever have RSO, remember: start low and go slow. Begin with a dose the size of half a grain of rice (very tiny amount). Wait several hours before taking more. Effects can be strong and long-lasting.

How RSO Is Generally Produced (Educational Overview)
While we recommend lab-tested commercial products, here's an educational overview of how professional RSO manufacturers produce this cannabis concentrate:
Traditional RSO Production Steps
1. Plant Material Selection
Commercial producers start with quality cannabis flower or trim. The starting material quality directly impacts the final product quality. Most commercial RSO uses high-quality flower rather than low-grade trim.
2. Solvent Selection
Professional operations use food-grade ethanol as the solvent of choice due to its efficiency and safety profile compared to other solvents. The solvent is chosen carefully based on extraction goals and safety considerations.
3. Extraction Process
Cannabis is soaked in cold ethanol to extract cannabinoids, terpenes, and other compounds. Temperature control is critical—colder temperatures preserve more delicate terpenes and plant compounds. This step typically takes 10-20 minutes in commercial settings.
4. Solvent Evaporation
The solvent is carefully evaporated using controlled heat or vacuum equipment. Modern commercial equipment uses precise temperature control and monitoring to preserve cannabinoids while removing all solvent residue. This is one of the most critical and dangerous steps if done improperly.
5. Quality Testing
The finished RSO undergoes third-party laboratory analysis for potency (cannabinoid profile), microbial contamination (bacteria, yeast, mold), pesticide residues, heavy metals, and solvent residue. Testing ensures the product meets regulatory standards and is safe for consumption.
6. Packaging and Storage
Final product is packaged in compliance with local regulations, typically in child-resistant containers with accurate labeling, testing results, and warnings. Proper storage conditions (cool, dark, sealed) are maintained throughout distribution.
The Serious Risks of Home Cannabis Extraction
If individuals choose to attempt cannabis extraction at home despite recommendations against it, they should understand the significant hazards:
⚠️ Fire and Explosion Hazard
Ethanol and other solvents are highly flammable. Improper use of heat or ignition sources can cause fires or explosions. Many serious burns and residential fires have resulted from home extraction attempts.
⚠️ Toxic Fume Exposure
Solvent vapors are harmful to inhale and can cause respiratory damage, dizziness, neurological effects, and long-term health problems with repeated exposure.
⚠️ Solvent Residue Contamination
Improper solvent evaporation can leave dangerous chemical residues in the final product. Consuming RSO with residual solvents poses serious health risks.
⚠️ Microbial Contamination
Without proper testing and sterile techniques, homemade products may contain harmful bacteria, mold, or other contaminants that cause infections or illness.
⚠️ Unknown Potency
Homemade RSO has unpredictable THC content, making it impossible to dose safely. This risks overdose or inconsistent effects.
⚠️ Legal Consequences
In many jurisdictions, cannabis extraction is illegal even where cannabis possession is legal. Home extraction can result in felony charges.
