Having been created in 1997, Rick Simpson Oil (or RSO) is not a new product. However, with the rise in popularity of CBD oils and tinctures, RSO is garnering more attention than it has in the past. What is the difference between RSO and CBD oil?

THC Content

THC is the psychoactive chemical that gives users a high. One of CBD’s benefits is that it lacks that chemical, while RSO contains a large THC count (between 50 and 60%).


Rick Simpson himself recommends that the oil-bearing his name be made with strains of the indicia flower since so many people are sensitive to the Sativa strain. CBD can be made with either strain.


CBD, since it is so low in THC, is not made with the marijuana flower; rather, the leaves are usually what make up the medicinal properties.


The story famously goes that Rick Simpson rubbed his oil on two cancerous tumors on his arm and they vanished. Thus, the use of RSO is primarily associated with cancerous growths, while CBD is used for all-over pain.

Both valuable for their roles in the medical world, RSO and CBD each serve a purpose. The differences between the two and slight, but important enough to impact how you use them.
