Although they are both derived from cannabis, they are extremely different.

CBD products are generally derived from the hemp plant. Whereas, RSO oil is derived from marijuana. CBD is non-psychoactive, whereas Rick Simpson Oil is psychoactive.
People have experienced amazing benefits from using both CBD and RSO, however, when it comes to defeating cancer, RSO is the main ingredient.
RSO is a highly concentrated form of cannabis, often containing massive amounts of THC.

CBD on the other hand is a non-psychoactive cannabinoid commonly found in the hemp plant (defined as a cannabis plant containing less than 0.3% THC).
The difference between RSO and CBD lies in these fundamental differences: RSO tends to be strongly psychoactive and far more concentrated than CBD oils.
RSO is a full spectrum product containing over 100+ cannabinoids (compounds). Whereas, CBD is a single cannabinoid.
