Comprehensive Guide On How To Make Rick Simpson Oil: A Professional-Grade Extraction Protocol

Rick Simpson Oil (RSO) is a full-spectrum cannabis extract produced by washing high-quality plant material with a solvent to isolate cannabinoids before undergoing a precise thermal evaporation process. To achieve a therapeutic-grade concentrate, the procedure must maintain a strict temperature threshold between 210°F and 230°F for decarboxylation while ensuring 100% solvent recovery or removal for safety and purity.

Critical Infrastructure and Material Acquisition

Successfully producing Rick Simpson Oil requires more than basic kitchen tools; it demands a controlled environment and specific materials to ensure the potency of the final resin and the safety of the technician. Because the process involves volatile solvents, the workspace must be equipped with high-volume ventilation or an outdoor setup to prevent the accumulation of flammable vapors. The use of high-THC indica strains is traditionally recommended for RSO, though high-CBD variants follow the same extraction logic.

Essential Equipment and Hardware

• Primary Extraction Vessel: Two 5-gallon stainless steel or food-grade plastic buckets.
• Stirring Implement: A long wooden or stainless steel paddle, strictly non-reactive.
• Filtration System: Fine-mesh cheesecloth for the initial strain, followed by unbleached laboratory-grade coffee filters for the secondary refinement.
• Thermal Processing Unit: A multi-setting rice cooker. This is preferred over a stove because it maintains a consistent temperature and prevents the oil from overheating.
• Precision Monitoring: An infrared digital thermometer or a high-accuracy candy thermometer.
• Storage and Dispensing: Medical-grade 10ml or 60ml oral syringes for measured dosing and long-term preservation.

Raw Material and Solvent Specifications

• Cannabis Biomass: One pound (450g) of high-quality, dried cannabis flower is the standard starting point, typically yielding 60 grams of oil.
• Extraction Solvent: Two gallons of 99% Isopropyl alcohol or 190-proof food-grade ethanol (Everclear). Ethanol is generally preferred for its lower toxicity profile.
• Budgetary Benchmark: Expect a cost of $1,500 to $2,500 for materials depending on the quality of the biomass.
• Time Duration: Allow 4 to 6 hours for the full extraction and evaporation cycle, followed by 24 hours of stabilization.

Tactical Extraction and Refining Workflow

The process of creating RSO is a chemical extraction that relies on the polarity of the solvent to strip the trichomes from the plant material. Accuracy in each phase determines the terpene retention and the bioavailability of the cannabinoids.

Step 1: Pre-Chilling and Material Preparation

Before starting the extraction, place both the cannabis biomass and the solvent in a freezer for at least 24 hours. This "Cold Ethanol Extraction" (QWET) method minimizes the extraction of chlorophyll, waxes, and lipids, resulting in a cleaner, more palatable oil. Once chilled, place the dried plant material into the primary stainless steel bucket. Ensure the material is broken down into small nuggets but not ground into a fine powder, as powderization makes filtration significantly more difficult and increases sediment in the final product.

Step 2: The Initial Solvent Wash

Pour the chilled solvent over the cannabis until it is fully submerged. Use your stirring implement to agitate the mixture for exactly three minutes. During this window, the solvent dissolves the resin glands containing THC, CBD, and other minor cannabinoids.

Warning: Do not exceed the three-minute mark during the first wash. Prolonged exposure to the solvent will begin to pull unwanted plant chlorophyll and bitter tannins into the mixture, darkening the oil and degrading its flavor profile and purity.

Step 3: Primary and Secondary Filtration

Decant the solvent-cannabis mixture through the cheesecloth into the second bucket. Squeeze the plant material to recover as much liquid as possible. This "green gold" liquid is now a cannabinoid-rich tincture. For professional-grade results, perform a secondary filtration by passing the liquid through unbleached coffee filters. This step is slow but critical; it removes microscopic plant matter that can cause the oil to burn or taste "grassy" during the evaporation phase.

Step 4: Solvent Evaporation and Volume Reduction

Transfer the filtered liquid into the rice cooker, filling it about three-quarters of the way. Set the rice cooker to the "White Rice" or "High" setting. As the liquid heats, the solvent will begin to evaporate.

Pro-Tip: If the rice cooker starts to overheat, add a few drops of water (10-12 drops per pound of starting material) to the mixture. This water helps protect the oil from burning as the solvent level drops, and the steam helps carry away the final traces of solvent.

Maintain a fan nearby to blow the fumes away from the unit. Ensure there are no open flames, cigarettes, or spark-producing electronics in the vicinity. As the level of liquid in the rice cooker drops, gradually add the remainder of your filtered tincture until it is all in the pot.

Step 5: Final Purge and Decarboxylation

When the liquid in the rice cooker has reduced to a thick, dark syrup and the bubbling slows significantly, the primary evaporation is complete. At this stage, the temperature is the most critical factor. The mixture must reach approximately 210°F to 230°F (99°C to 110°C) to facilitate decarboxylation—the chemical reaction that converts THCA into the psychoactive and therapeutic THC.

Transfer the thick oil into a stainless steel measuring cup or a small silicone heat-resistant container. Place this on a coffee mug warmer or in an oven set to 230°F. Watch for "CO2 bubbles." When the oil stops producing small bubbles, the decarboxylation process is complete. This usually takes 30 to 60 minutes.

Step 6: Syringe Packaging and Storage

While the oil is still warm and fluid, draw it into the plastic syringes. This allows for precise measurement during use. If the oil cools and becomes too viscous to draw, gently warm the container in a warm water bath. Store the syringes in a cool, dark place (like a refrigerator) to prevent the degradation of cannabinoids into CBN, which would increase the sedative effect but decrease the primary therapeutic potency.

Thermodynamic Benchmarks and Solvent Compatibility

The following table outlines the technical parameters required to maintain the structural integrity of the cannabinoids during the RSO production process.

Extract Quality Anomalies and Remediation

Despite following a strict protocol, environmental variables can impact the consistency and potency of Rick Simpson Oil. Monitoring the physical state of the extract during the final purge is essential for identifying failures.

• Symptom: Oil appears cloudy or has a milky texture.

  
  
  
  • Root Cause: Water contamination or residual moisture in the starting material. This often happens if the cannabis was not properly dried or if low-grade alcohol was used.
  • Actionable Fix: Re-heat the oil at 220°F in a vacuum oven or on a steady heat plate until all steam/bubbling ceases. This "dries" the oil and clarifies the resin.

• Symptom: Harsh, acrid smoke or bitter "burnt" flavor.

  
  
  
  • Root Cause: Thermal degradation caused by the rice cooker reaching "Warm" mode too late or the oil being left on high heat after the solvent evaporated.
  • Actionable Fix: Unfortunately, burnt oil cannot be reversed. To prevent this, always add the water drops mentioned in Step 4 and use a digital thermometer to pull the oil from the heat source once it reaches 210°F.

• Symptom: Oil remains liquid/runny at room temperature.

  
  
  
  • Root Cause: Incomplete solvent evaporation or high terpene content (which acts as a natural solvent).
  • Actionable Fix: Extend the finishing time on a coffee mug warmer for an additional 2 hours. If the consistency does not improve, the decarboxylation may be incomplete; increase the temperature slightly to 230°F for 15 minutes.

• Symptom: Excessive "Grassy" or Green Appearance.

  
  
  
  • Root Cause: Excessive agitation during the wash or using room-temperature solvent.
  • Actionable Fix: Winterization. Dissolve the oil in a small amount of 190-proof ethanol, freeze for 48 hours, and filter through a 5-micron filter to remove the precipitated fats and waxes.

Frequently Asked Questions

What is the best solvent to use for making Rick Simpson Oil?

High-proof food-grade ethanol is the industry standard because it is safer for human consumption and highly efficient at stripping cannabinoids. While 99% Isopropyl alcohol is effective and traditional to the Rick Simpson method, it requires much more rigorous purging to ensure no toxic residues remain in the final medicinal product.

How much RSO does one ounce of cannabis produce?

On average, one ounce (28 grams) of high-quality cannabis will yield between 3 and 5 grams of RSO. The yield depends heavily on the trichome density of the specific strain used; higher THC percentages (20%+) will naturally result in a higher volume of concentrated oil.

Can I make Rick Simpson Oil on an electric stove?

Using a stove is highly discouraged due to the difficulty of maintaining a precise, low temperature. Most stovetops, even on the lowest setting, can easily exceed the boiling point of cannabinoids or the flashpoint of the solvent, creating a significant fire hazard and potentially ruining the therapeutic properties of the oil.

Why is decarboxylation necessary for RSO?

Raw cannabis contains THCA, which is non-psychoactive and has different therapeutic properties than THC. Decarboxylation uses heat to remove a carboxyl group, "activating" the THC so it can cross the blood-brain barrier and provide the potent effects associated with the Rick Simpson protocol.

How long does RSO stay potent when stored?

When stored in medical-grade syringes in a cool, dark, and airtight environment, RSO can maintain its peak potency for 12 to 24 months. Over time, THC will slowly degrade into CBN, which will make the oil more sedative but less effective for certain targeted therapeutic applications.
