Previous studies have shown that consuming hemp foods can lead to positive results in drug screenings. A routine drug test does not detect CBD, so using hemp oil or other related products will not result in a failed drug test. However, the CBD industry is not strictly regulated in the United States, and there is a large gray market in Canada. This means that it is possible to fail a drug test with a CBD product.
In one study, volunteers ate snack bars and other foods made from pressed hemp seeds. Hemp seed oil is primarily used in skin care products as a moisturizer, but it can also be found in foods such as salad dressings. It is illegal to drive or operate machinery while under the influence of cannabis, just like alcohol and other drugs. The type of plant used to make the product does not matter when it comes to drug tests; what matters is if there are detectable levels of THC present in urine, blood, etc. The acceptable amount of THC in the blood varies by location, legal framework, industry, and purpose.
According to the Centers for Disease Control (CDC), 16% of car accidents are drug-related, with marijuana use being the second most common. Generally, an unusually large amount of hemp oil or hemp seeds would be needed to test positive for drugs. If your drug test still comes back positive, your CBD product may have been cross-contaminated during the manufacturing process. Drug tests are primarily used to detect the presence of prohibited substances that improve an athlete's performance (e.g., steroids). In this study, ingesting hemp seed food products resulted in urine samples that tested positive for marijuana.
You may not pass a drug test for THC-based marijuana if you have consumed hemp oil, hemp seed, or hemp seed extract - an ingredient found in many CBD oils and supplements.
