CBD Oil: What It Is, Safety and How Products Differ

What is CBD?

CBD is cannabidiol, a compound found in cannabis. “Cannabis oil” is a broad term that can include CBD-rich oils. Compare the actual ingredients and concentrations rather than relying on product names alone. It does not cause the characteristic THC high, but that does not make it risk-free. The CDC’s CBD overview describes possible adverse effects and interactions with medicines.

CBD oil and hemp seed oil are different

CBD oil contains cannabidiol; hemp seed oil is extracted from seeds. According to the FDA, cannabis seeds do not naturally contain THC or CBD, although traces can be transferred from other plant parts during processing. Seed oil is therefore not interchangeable with a CBD extract. Read more about types of medical cannabis oil.

CBD oil for pain: interpreting evidence

A study of cannabis, a THC–CBD combination or a specific medicine does not establish that every CBD oil relieves pain. Ask what was tested, in whom and by which route. The CDC describes limited evidence for most types of pain. Our cannabis oil for pain guide helps you prepare questions for your clinician.

CBD oil for sleep or anxiety

Evidence on cannabinoids, sleep and anxiety depends on the preparation and population studied. The word CBD on a bottle does not establish whether the product will help with a particular symptom. The NCCIH overview explains research limitations. Describe whether your concern is falling asleep, waking frequently, pain at night or anxiety; these need different assessments.

Questions to take to a clinician or pharmacist

• What are the exact ingredients and concentrations?
• Does the product also contain THC, and how much?
• Does the evidence concern my medical condition?
• Could it interact with my medicines or supplements?
• Who will assess the response and unwanted effects?

Bring the product information and a complete medicine list. Price, packaging and online promises do not establish individual suitability.

CBD side effects

Possible risks include sleepiness, diarrhea, liver injury and interactions with medicines. The CDC’s safety information also notes gaps in knowledge about long-term use. Do not change prescribed medicines because of general online information.
