On the molecular level, CBD is the same compound regardless of whether it’s found in high-THC or low-THC cannabis plants. There are, however, several differences between CBD products, depending on where the CBD is sourced from.

Hemp-derived CBD oil usually contains high concentrations of CBD, but its THC content doesn’t exceed the legal 0.3% limit. On the other hand, marijuana-derived oil is sourced from selectively bred high-CBD strains, it also comes with significant amounts of THC, ranging between 5% and 30%.
