Possible Side Effects
Clinical research has shown that CBD oil can trigger side effects. Severity and type can vary from one person to the next.7 Common symptoms include:
- Anxiety
- Changes in appetite
- Changes in mood
- Diarrhea
- Dizziness
- Drowsiness
- Dry mouth
- Nausea
- Vomiting
CBD oil may also increase liver enzymes (a marker of liver inflammation). People with liver disease should use CBD oil with caution, ideally under the care of a doctor who can regularly check blood liver enzyme levels.
CBD oil should be avoided during pregnancy and breastfeeding. A 2018 study from the American Academy of Pediatrics warned women to avoid marijuana during pregnancy due to the potential risks to a baby's development.8 Although it is unclear how CBD contributes, CBD is known to pass through the placental barrier.
If you are thinking about using CBD oil to treat a health condition, be sure to speak with your healthcare provider to ensure that it is the right option for you.
Since some CBD oils contain trace amounts of THC, you should avoid driving or using heavy machinery when taking CBD oil, particularly when first starting treatment or using a new brand.
