Previous studies have indicated that consuming hemp-based foods can lead to positive results in urine tests. Laws prohibiting the use of cannabis in the workplace vary from state to state. Hemp protein contains a small amount of THC, but not enough to fail a drug test. Hemp protein does not affect a urine drug test for cannabis or MMJ. The THC content of less than 0.3% in hemp is below the level required by federal law and is therefore safe to consume.
Ingesting hemp seeds is unlikely to give a false positive drug test, as it would require consuming very large doses of hemp seed products to get a positive result (according to studies). However, since hemp contains THC, the cannabinoid found in marijuana that causes people to get high, products that contain hemp seeds or other by-products may cause some people to fail the tests. To be sure, buy seeds that are produced in Canada, where the exported hemp products meet strict standards. Misunderstanding about the different parts of the cannabis plant and their effects on the body has caused some to worry that hemp seeds may be causing false positives in marijuana tests. Bechtel states that the lab routinely tests drugs and does not find traces of THC in people who eat hemp as a health food but do not use marijuana, adding: “People need to realize that it will take a lot of seeds, a bag of seeds, or more to test positive.
Hemp seed products along with flax, chia and poppy seeds are becoming increasingly popular supplements found in many foods today, from bagels to protein shakes.
