A condition in which a transplant attacks the body (graft-versus-host disease or GVHD). Graft-versus-host disease is a complication that can occur after a bone marrow transplant. In people with this condition, donor cells attack the person's own cells. Early research shows that taking cannabidiol daily starting 7 days before bone marrow transplant and continuing for 30 days after transplant can extend the time it takes for a person to develop GVHD.
Cannabidiol has antipsychotic effects. The exact cause for these effects is not clear. But 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. Cannabidiol might also block some of the psychoactive effects of delta-9-tetrahydrocannabinol (THC). Also, cannabidiol seems to reduce pain and anxiety.
We’ve established the fact that naturally occurring CBD is the same CBD regardless of the plant it came from. However, CBD and CBD oil are not in fact the same thing. As we’ve seen above, CBD is a chemical compound with sharply defined characteristics, while CBD oil is a mixture of various natural substances as they are derived from the plant of cannabis.
State and local governments may also regulate CBD. For example, the Massachusetts Department of Agricultural Resources issued a rule in June 2019 aligning state CBD regulations with FDA regulations. This means that although recreational marijuana is legal in the state, CDB cannot legally be sold in food or as a dietary supplement under state law.
