Rick Simpson Oil sounds like a fancy term for quick-wash ISO hash.
Isopropyl Alcohol (ISO) and ethanol can extract both polar and non-polar compounds. THC is primarily non-polar, as is most of the cannabinoids and terpenes that are desirable for extraction.
However, chlorophyll, sugars, salts, etc. are polar, and given enough time will also dissolve into the ISO and ethanol. There are also fats/waxes that are non-polar and can be pulled out when using ISO or ethanol as the solvent.
Because the majority of the cannabinoids are concentrated in trichome structures (which have relatively high surface area to volume ratios, and very little plant material standing between the resins and the outside world), and because these two solvents tend to be more non-polar than polar, the trichome cannabinoids dissolve at the highest rates. This is why a quick (30 seconds to 3 minutes) ISO or ethanol wash will produce a higher quality product than a several hour ISO or ethanol wash. Stirring/gently agitating the mixture is going to help break up the trichomes without breaking up the rest of the plant material, and release a little extra resin into the solvent.
It should be noted that these techniques are dependent on the starting material. You want to start with buds, not leaves and stems. The higher quality product you start with, the higher the final quality can be. It should also be noted that these techniques focus more on quality of the final product rather than overall quantity of final product. Older methods using long solvent soaks get all of the THC out of the plant material, but also draw out everything else you don't want, and require a lot of post-processing to get something you would actually want to consume.
My suggestion would be to use our forum search function at the top of the page to search for "quick ISO wash" techniques. You may also want to look into winterization or cold ISO wash stuff as well.
Also remember that ISO is really bad for you, even in vapor form, and high-proof ethanol is extremely flammable and can really fuck you up if it is evaporated in large quantities in a poorly-ventilated area. Make sure you do some research on proper safety practices when working with solvents.
Best of luck
