CBD (Cannabidiol)

Cannabidiol (CBD) is a compound found in marijuana. CBD is not impairing, meaning it does not cause a “high.” It is marketed in many consumer products, including foods, oils, lotions, capsules, and cosmetics.

CBD can be derived from hemp or from non-hemp plants. Hemp is defined as any part of the cannabis sativa plant with no more than 0.3% of tetrahydrocannabinol (THC), the mind-altering substance in marijuana.

Is CBD a Medicine?

Scientists are still learning about how CBD affects the body. The U.S. Food and Drug Administration (FDA) approved Epidiolex, a medicine that contains purified CBD from hemp, to help treat rare seizure disorders. The FDA has concluded that this drug is safe and effective for this intended use. However, other marketed products and uses of CBD may not be FDA approved.

Potential Harms & Side Effects

Using CBD products is not risk-free. The FDA has limited data on CBD safety. Consider these possible side effects and risks before using CBD:

  • Liver damage
  • Interference with other drugs you are taking, which may lead to injury or serious side effects
  • Drowsiness or sleepiness
  • Diarrhea or changes in appetite
  • Changes in mood, such as irritability

CBD Use During Pregnancy is Not Recommended

The potential health effects of using CBD products during pregnancy are currently unknown. In animals, high doses of CBD have caused negative effects on developing fetuses.

We do not know if CBD is passed to a baby through breast milk. Since negative effects have been associated with CBD use, people who are breastfeeding are encouraged to avoid CBD.

Keep CBD Away from Children

We do not know the effects of CBD on children’s developing brains. If you use products that contain CBD or THC, keep them in childproof containers and out of the reach of children.

For questions, contact your healthcare provider, your health department, or your local or regional poison control center at 1-800-222-1222, or call 911 if it’s an emergency.
