What is CBD?

Cannabidiol (CBD) is a chemical in the Cannabis sativa plant, also known as marijuana or hemp. Since cannabidiol has been studied as a new drug, it can’t be legally included in foods or dietary supplements. Also, cannabidiol can’t be included in products marketed with therapeutic claims. 

How does CBD work?

Cannabidiol has antipsychotic effects. The exact cause for these effects is not clear. 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. Also, cannabidiol seems to reduce pain and anxiety.

What can CBD be used for?

Currently, the only CBD product approved by the Food and Drug Administration is a prescription oil called Epidiolex. This product is a prescription drug for treating seizures caused by Dravet syndrome or Lennox-Gastaut syndrome. It has also been shown to reduce seizures in people with tuberous sclerosis complex, Sturge-Weber syndrome, febrile infection-related epilepsy syndrome (FIRES), and specific genetic disorders that cause epileptic encephalopathy. But it’s not approved for treating these other types of seizures.

There is insufficient evidence to support the effectiveness of CBD on the following conditions. We need more research with sufficient high-quality evidence in human studies.

  • Bipolar disorder. Early reports show that taking cannabidiol does not improve manic episodes in people with bipolar disorders.
  • A type of inflammatory bowel disease (Crohn disease). Early research shows that taking cannabidiol does not reduce disease activity in adults with Crohn disease.
  • Diabetes. Early research shows that taking cannabidiol does not improve blood glucose levels, blood insulin levels, or HbA1c in adults with type 2 diabetes.
  • A movement disorder marked by involuntary muscle contractions (dystonia). Early research suggests that taking cannabidiol daily for 6 weeks might improve dystonia by 20% to 50% in some people. Higher quality research is needed to confirm this.
  • Insomnia. Early research suggests that taking 160 mg of cannabidiol before bed improves sleep time in people with insomnia. However, lower doses do not have this effect. Cannabidiol also does not seem to help people fall asleep and might reduce the ability to recall dreams.
  • Multiple sclerosis (MS). There is inconsistent evidence on the effectiveness of cannabidiol for symptoms of multiple sclerosis. Some early research suggests that using a cannabidiol spray under the tongue might improve pain and muscle tightness in people with MS. However, it does not appear to improve muscle spasms, tiredness, bladder control, the ability to move around, or well-being and quality of life.
  • Withdrawal from heroin, morphine, and other opioid drugs. Early research shows that taking cannabidiol for 3 days reduces cravings and anxiety in people with heroin use disorder that are not using heroin or any other opioid drugs.
  • Parkinson’s disease. Some early research shows that taking cannabidiol daily for 4 weeks improves psychotic symptoms in people with Parkinson’s disease and psychosis.
  • Schizophrenia. Research on the use of cannabidiol for psychotic symptoms in people with schizophrenia is conflicting. Some early research suggests that taking cannabidiol four times daily for 4 weeks improves psychotic symptoms and might be as effective as the antipsychotic medication amisulpride. However, other early research suggests that taking cannabidiol for 14 days is not beneficial. The conflicting results might be related to the CBD dose used and duration of treatment.
  • Quitting smoking. Early research suggests that inhaling cannabidiol with an inhaler for one week might reduce the number of cigarettes smoked by about 40% compared to baseline.
  • Social anxiety disorder. Some early research shows that taking cannabidiol 300 mg daily does not improve anxiety during public speaking in people with social anxiety disorder. However, other early research in people with social anxiety disorder suggests that taking a higher dose (400-600 mg) may improve anxiety associated with public speaking or medical imaging testing. Also, some research in people who do not have social anxiety disorder shows that taking cannabidiol 300 mg might reduce anxiety during public speaking.
