Cannabinoids are naturally produced in the body and they are important for stability. People take or apply cannabidiol to treat a variety of symptoms, but its use is controversial. There is some confusion about what it is and how it affects the human body. People tend to use prescription or over-the-counter drugs to relieve stiffness and pain, including chronic pain. More recently, scientists have discovered that certain components of marijuana, including CBD, are responsible for its pain-relieving effects.
