Unlike some pain medications, CBD is not addictive and does not have any intoxicating effects, offering much relief for people who have chronic pain. Because the THC content in CBD oil may vary, depending on the state it’s sold, there may be restrictions. For example, in some states, CBD oil is sold legally if all of the THC is removed.
However, cannabidiol seems to prevent the breakdown of a chemical in the brain that affects pain, mood, and mental function. Preventing the breakdown of this chemical and increasing its levels in the blood seems to reduce psychotic symptoms associated with conditions such as schizophrenia.
