Hemp Seed Oil Drug Test: Results

This is a scientific guide.

Based on the latest medical studies.

  • know exactly how long and short term use of hemp seed oil will impact your drug test
  • know the hemp seed oil dosage tested and types of drug tests administered
  • find out if long term consumption of hemp seed oil causes a positive drug test

Let’s get started.

Our Summary: It is generally believed that taking CBD will not cause you to fail a drug test for marijuana…but is that true?  New CBD research has the answer. (2)

Background:

  • CBD comes mostly from hemp.
  • Hemp and marijuana are the same species of plants.
  • The difference between marijuana and hemp comes down to the total amount of THC found in a specific plant or strain. (3)

Differences between hemp and marijuana:

  • If a cannabis plant produces a lot of THC then it’s considered a marijuana plant.
  • If it produces no THC (or “virtually” none), then it’s considered a hemp plant.
  • Marijuana plants produce high levels of THC.
  • Sometimes, THC levels in marijuana plants can be above 30% depending on the growing conditions and the strain.
  • It took many generations of selective breeding to increase the THC in these select marijuana strains to such high levels.
  • Hemp, on the other hand, has been bred to have very low levels of THC and higher levels of non-intoxicating cannabinoids like CBD. (4)

Legal definition of hemp: For a cannabis plant to be considered hemp, it must have less than .3% THC content.  That’s why it’s said that hemp has “virtually no THC.”

Now, back to the study.

Hemp seed oil benefits: As you can imagine, nobody wants to test positive for using marijuana simply because they use a non-intoxicating CBD product for pain or to help with anxiety. (5)

Procedure:

  • Researchers in Korea drug tested the urine of 64 participants to see if hemp seed oil capsules would cause a positive result (“failing the drug test”) for a marijuana drug test.
  • The researchers tested the first urine samples after 1 week and then collected urine samples from the participants for the next 12 weeks as they continued taking the hemp seed oil capsules daily.
  • At the end of the 12 weeks, the researchers drug tested all the samples. (6)

Conclusion: In the long term test, only two urine samples showed trace amounts of THC but the trace readings were well below the level at which they would cause a test to be positive for THC or marijuana. (7)
