RSO is a full-spectrum cannabis extract consumed orally or applied topically. Distillate is a highly refined, single-cannabinoid oil used in vapes and edibles. Live resin is a full-spectrum extract made from fresh-frozen cannabis, designed for inhalation. Three extracts, three different production processes, three different experiences.
They sit on the same shelf, often at similar price points, and are rarely explained side by side in a way that makes the differences clear.
Where RSO Came From
Rick Simpson was a Canadian engineer who developed a concentrated cannabis oil in the early 2000s and began distributing it to others. He became a known cannabis activist and the oil he created became known as Rick Simpson Oil, or RSO.
Simpson built his extraction process around preservation rather than refinement. The goal was to keep as much of the plant’s compound profile intact as possible in a form that could be consumed orally or applied to skin. That approach is still reflected in how RSO is made today.
What Is RSO and How Is It Made?
RSO is made from dried, cured cannabis flower. The plant material is soaked in a solvent, most commonly high-proof ethanol, which draws out cannabinoids, terpenes, flavonoids, plant waxes, and chlorophyll. The plant material is then removed and the solvent is evaporated under controlled heat. What remains is a thick, dark, sticky oil.
The dark color comes from the chlorophyll and plant compounds that stay in the final product because nothing is filtered or refined out. The strong, earthy, slightly bitter taste comes from the same source. Both are direct results of an intentionally unrefined process.
Because nothing is removed, RSO is a full-spectrum extract. It contains THC, CBD, and a range of minor cannabinoids alongside terpenes and other plant compounds. Those compounds interact in what is called the entourage effect: a term describing how the combination of cannabinoids and terpenes may influence the overall experience differently than any single isolated compound would on its own.
RSO is typically packaged in an oral syringe without a needle, which allows for precise dosing.
How Do You Use RSO?
RSO is not suitable for vaping. The residual plant material, waxes, and lipids it contains make it unsuitable for inhalation. It is taken orally or applied topically.
Sublingually: A small amount, roughly the size of a grain of rice, is placed under the tongue and held for 30 to 60 seconds before swallowing. Onset can begin in 15 to 45 minutes, and effects typically last 6 to 8 hours or longer.
Mixed into food: RSO can be mixed into food, particularly something with fat content like peanut butter or olive oil. When eaten, onset is slower, often 30 minutes to 2 hours, with a similarly long duration.
In capsule form: RSO can be loaded into capsules for a more neutral format without the taste or texture of the oil.
Topically: RSO can be applied directly to skin.
RSO is highly concentrated. Starting with a small amount and increasing gradually based on response is the standard guidance for new users.
How Does RSO Differ From Distillate and Live Resin?
The three extracts differ in starting material, extraction method, what gets kept or removed, and how they are consumed.
| RSO | Distillate | Live Resin | |
|---|---|---|---|
Starting Material | Dried, cured flower | Dried, cured flower | Fresh-frozen plant |
Spectrum | Full-spectrum | Isolated cannabinoid | Full-spectrum |
Appearance | Dark, thick, tar-like | Clear to amber, fluid | Golden, visous |
Taste | Strong, earthy, bitter | Neutral, near-flavorless | Bold, strain-specific |
Entourage effect | Yes | Minimal to none | Yes |
Can be vaped? | No | Yes | Yes |
Best for | Oral / topical use | Vaping, edibles | Vaping, dabbing |
RSO vs Distillate
Distillate is produced through fractional distillation: cannabis oil is heated under vacuum until specific compounds vaporize at their individual boiling points, then condensed back into liquid. The result is a highly refined oil, typically 90 to 99 percent pure THC or CBD, with terpenes, flavonoids, waxes, and plant matter removed in the process.
Many distillate products add terpenes back after distillation, either cannabis-derived or from other botanical sources, to reintroduce flavor and aromatic character. Without those additions, distillate is nearly flavorless and odorless.
RSO retains the full compound profile of the plant. Distillate isolates a single cannabinoid and removes almost everything else. The two extracts start from the same raw material and end up in completely different places.
RSO vs Live Resin
Live resin is also full-spectrum, but starts from fresh-frozen rather than dried and cured plant material. Cannabis harvested for live resin is flash-frozen immediately after cutting, which preserves the terpene and cannabinoid profile of the living plant before drying and curing can degrade it. That is where the name comes from.
After freezing, the plant material goes through solvent extraction using hydrocarbons like butane or propane. Because the terpenes are preserved from the start, live resin has a more complex and strain-specific flavor profile than RSO or distillate. It is lighter in color and intended for inhalation through vaping or dabbing, unlike RSO.
RSO uses cured flower and ethanol and is designed for oral or topical use. Live resin uses fresh-frozen plant material and hydrocarbon solvents and is designed for inhalation. The starting material and intended consumption method are different for each.
Who Uses RSO?
RSO is used by people who prefer oral or topical consumption over inhalation and by those who want a broad-spectrum cannabinoid product rather than an isolated one. Because it retains the full compound profile of the plant, it is a different experience from distillate-based edibles, which contain isolated THC or CBD rather than the full plant range.
RSO produces psychoactive effects when it contains THC, which most RSO does. The concentration is high and the duration is long, both of which are relevant for anyone new to it.
RSO at Ivy Hall
Ivy Hall carries RSO in gummy, syringe, and capsule formats across multiple brands and cannabinoid ratios.
RSO Gummies
Savvy Guap RSO Melon Crash 2:1 THC:CBN Gummies is a good starting point if you are new to RSO gummies and want something beyond straight THC. It is an indica single-piece gummy with 100mg THC and a 1:2 CBN:THC ratio, watermelon and cantaloupe flavor. The CBN alongside the THC gives it a heavier, more sedating character, which makes it a useful illustration of how cannabinoid ratios change the experience compared to a standard RSO gummy.
Encore Sour Black Cherry RSO Gummies is worth looking at if you are curious about RSO but the oil format puts you off. It is a hybrid 10-pack with 100mg total THC made with RSO, so you get the full-spectrum profile in a familiar edible format without any of the texture or taste of the oil itself.
RSO Syringes
Remedi Relief RSO is a hybrid 0.5g syringe with 70.73% total THC. The syringe format works sublingually, mixed into food, or loaded into capsules, so it fits a range of routines depending on how you prefer to consume RSO.
Frequently Asked Questions
Can RSO be vaped?
No. RSO contains residual plant material, waxes, and lipids that make it unsuitable for inhalation. It is intended for oral or topical use only.
How long does RSO take to work?
Taken sublingually, onset can begin in 15 to 45 minutes. When swallowed as an edible or taken in capsule form, onset typically ranges from 30 minutes to 2 hours. Effects can last 6 to 8 hours or longer depending on the dose and the individual.
Does RSO get you high?
Yes, if it contains THC. RSO is highly concentrated, so the psychoactive effects can be pronounced. Starting with a small dose and waiting to assess the response before taking more is the standard approach.
What does RSO taste like?
Strong, earthy, and slightly bitter. The flavor comes from the chlorophyll and plant compounds that remain in the unrefined oil. People who find the taste difficult often mix it into food, take it in capsules, or use an RSO-infused gummy instead.
What is the entourage effect?
The entourage effect is a term used to describe how cannabinoids, terpenes, and other plant compounds may interact with each other and influence the overall experience. Full-spectrum products like RSO and live resin retain a broad compound profile. Distillate, which isolates a single cannabinoid, does not.
Can RSO be applied to skin?
Yes. RSO can be applied topically. When used this way it does not typically produce psychoactive effects, as the cannabinoids do not enter the bloodstream the way they do through oral consumption.
How is RSO different from CBD oil?
CBD oil is typically formulated to contain cannabidiol with little or no THC and is widely available outside of dispensaries. RSO is a full-spectrum extract that is usually high in THC along with other cannabinoids and plant compounds. The two products have different compositions, different legal statuses in many places, and different effects.
The Right Extract for the Right Reason
RSO, distillate, and live resin are each built for different things. RSO is an oral and topical product that retains the full plant profile. Distillate is a refined, single-cannabinoid product suited for vaping and edibles. Live resin is a full-spectrum inhalable extract that preserves the fresh plant’s terpene character.
Which one fits depends on how someone wants to consume cannabis and what cannabinoid profile they are looking for. The Ivy Hall team is available to help work through those questions for anyone who wants a hand before choosin
