RSO (Rick Simpson Oil) is an extremely potent, oil-based, full-spectrum cannabis concentrate that has been designed to preserve all of the natural cannabinoids and terpenes found within the original cannabis plant. In contrast to refined isolates which contain fewer active ingredients, the use of RSO will provide you with a stronger, longer lasting and more intense cannabis experience.

RSO can be characterized by its thick and syrupy texture as well as being extremely dark in color (usually appearing as either a deep amber or rich brown). As a result of its high concentration of THC, RSO should be used exclusively by those that are experienced at using marijuana or would like to utilize extremely small, controlled dosages.

RSO is a very unique oil due to its unrefined nature. The chemical composition of RSO has the potential to contain all the Cannabinoids, Terpenes and other Compounds found in Cannabis plants which could interact with each other and produce what some call a Full-Spectrum Effect. Therefore, this can make an individual’s overall experience from using RSO stronger and more complex compared to most Single Compound Extracts.
RSO Oil is frequently referenced within Medical Cannabis Contexts and is often utilized as Supportive Care for:
The main cannabinoid present in this RSO is \Delta^9-THC at 80.379%. This provides for the drug’s strong and prolonged effect. While CBG may be responsible for some of the broad spectrum interactions, it has been suggested that CBN is involved in creating milder, more sedating effects. Therefore, the combination of \Delta^9-THC, CBG, and CBN provide for an extremely potent product.
RSO oil can be a reasonable option because of how little you have to take each time. In addition, if you are using this product on a regular basis, the strength of RSO will give you more bang for your buck than many other low potency cannabis products that contain less THC. And while most topical marijuana-based products require a specific application method (i.e. rub directly onto skin), RSO can be used as an oral supplement, placed under the tongue (sublingual) when desired, added to your favorite foods or beverages, or even rubbed into specific areas as needed.
Start by using an extremely low dose (approximately that of a single grain of rice) and then wait to see how it affects you before adding another one. The onset time is generally slow developing over 6-9 hours for oral ingestion and can be quicker for sublingual administration which takes approximately 1 min after holding the product in your mouth.
