CBD, Hemp, and Drug Tests
Question: Can hemp oil or CBD (cannabidiol) supplements cause me to fail a drug test?
Answer: It is possible to fail a drug test for marijuana based on THC in a hemp oil, hemp seeds, or CBD supplement, but it is unlikely at suggested or typical serving sizes, as explained in the What CL Found section of the CBD & Hemp Supplements Review.
Among the CBD oils and pills ConsumerLab has tested, the majority have contained less than 0.2 mg of THC per suggested maximum daily serving. Studies have shown that most people who consume about 0.4 or 0.6 mg of THC do not test positive on urine tests for marijuana -- although a small percentage may, possibly due to individual variation in how THC is absorbed and metabolized.
