Rick Simpson’s oil, better known as RSO, is one of the earliest examples of modern medical marijuana extracts. It’s first introduced in the early 2000s and has since become a staple for many medical marijuana patients due to its potent and therapeutic effects. To better understand RSO, its uses, and its benefits, let’s first find out about the man behind the drug: Rick Simpson.

Rick Simpson Oil is a cannabis extract named after the medical marijuana activist who created it. Simpson claims that applying the oil to the cancerous spots on his skin removed the spots within days. Rick Simpson’s Oil (RSO) is unique in that it contains higher levels of tetrahydrocannabinol (THC) than other medicinal cannabis-extracts. Though there is some instances to support the use of cannabis to treat cancer, the medical community needs more direct evidence of its effectiveness and safety for humans before making factual claims. Scientists continue to explore the use of cannabis products in cancer treatment.
