Rick Simpson Oil, or RSO, is a cannabis concentrate named for its medicinal marijuana activist of a creator. Containing higher levels of THC than most oils, it's known for having a more psychoactive effect. It was originally invented to assist in research for cancer treatments as a result of Simpson's own diagnosis with skin cancer. The recipe is widely available because he encourages others to make their own.
