CBD (Cannabidiol) oil is derived from hemp. Many people confuse hemp with marijuana, but hemp is a very different plant. Marijuana and hemp may share the same scientific name, Cannabis sativa, but they are not the same.
Marijuana is cultivated primarily for its psychoactive cannabinoid, a chemical compound called tetrahydrocannabinol or THC, for recreational and medicinal use. Marijuana contains both THC and CBD.
Hemp contains only a trace of THC, less than 0.3% compared to marijuana’s hefty 5-35%. The main cannabinoid in hemp is CBD, but there are over 100 other cannabinoids in hemp, as well as compounds that produce tastes and scents called terpenes (e.g. citrusy smell of oranges, unique aroma of pine trees, or sweet flower smell of lavender).
