It is possible to fail a drug test for marijuana based on THC in a hemp oil, hemp seed, or hemp seed extract — the ingredient in many CBD oils and supplements. Unusually large amounts of hemp oil or hemp seed would normally be required to cause a positive drug test.
However, with hemp extracts, i.e., CBD oils, there is roughly a 10% chance of failing a drug test with low to moderate doses of CBD, and this will be influenced by individual variation in how THC is absorbed and metabolized. As dosage increases, the risk increases: one study found a 50% of testing positive with daily use of a moderately high dose of CBD. Note that some products contain very little THC and are, essentially, THC-free. For details, including the amounts of THC that ConsumerLab.com detected in specific products, see the What CL Found section of the CBD Oils & Hemp Extracts Review.
Will Hemp Oils and Other Hemp Products Test Positive on Drug Tests?
As a healthcare professional, a common question that I receive when talking to patients and clients who are interested in incorporating the use of hemp products or hemp foods into their daily routine is:
“Will eating hemp foods show up positive for THC on a drug test?”
According to the research studies available, the answer to this is question is a resounding NO! Regular consumption or use of commercially made hemp foods (such as seeds, cooking oil, cereals, milk, granola) or hemp products (lotions, shampoos, lip balms, etc.) will not show a positive result for THC on a drug test.
Hemp-based foods and hemp body products commercially produced and sold in the United States are not legally allowed to contain the potentially psychoactive cannabinoid known as THC (Delta-9 Tetrahydrocannabinol). If a laboratory-tested hemp product did happen to contain trace amounts of this compound, it would be in such small quantities that it would likely require exorbitant amounts of ingestion or use for it to even remotely begin to show up in the smallest amount on a drug test.
However, with that said, consuming non-commercially produced hemp foods, hemp-based oils, or using homemade hemp-based products may have risks to test positive. Non-federally regulated foods and products, like those purchased from a dispensary, farmer’s market, or even products bought online, do not necessarily follow any sort of federal food safety guidelines or food and drug administration regulations. When purchasing these types of hemp products, make sure you use caution and ask questions about how they were made and whether they were tested before being packaged.
Still, generally speaking, hemp-based food and products (federally regulated ones, anyway) shouldn’t show a positive result for THC on a drug test, so keep enjoying your hemp snacks!
