CBD is often marketed as wellness-related, but it can have risks and many questions remain. This guide summarizes FDA safety information and encourages shoppers to get individualized advice from a healthcare professional.
Educational information only, not medical advice or a product recommendation. Product examples, where included, come from official shop listings captured in October 2026. Listings are illustrative, not ranked or independently tested; availability can change.
Potential effects described by FDA
FDA information identifies concerns including possible liver injury, interactions with other medicines, drowsiness or changes in alertness, gastrointestinal distress, and mood changes. Risks can depend on the person, product, amount, and other substances.
Ask before combining CBD with medicines
CBD may affect how other medicines work, and other medicines may affect CBD. Ask a healthcare professional or pharmacist before combining CBD with prescription medicines, over-the-counter medicines, alcohol, herbs, or supplements.
Pregnancy, breastfeeding, and children need special caution
FDA strongly advises against CBD use during pregnancy or while breastfeeding. Keep CBD and cannabinoid products securely away from children; accidental ingestion can require urgent advice.
A product label or COA is not a safety guarantee
A COA can show test results for a particular sample, but it does not establish medical safety, the right amount for you, or effectiveness. FDA notes quality concerns and unknowns about long-term use.
