Will Hemp Seed Oil Cause A Positive Drug Test?

You will not fail a drug test from consuming hemp seed oil. According to a large 2019 study, you can use hemp seed oil from high-quality suppliers without testing positive in a drug screening. The saliva and urine drug tests conducted in this study are significantly more sensitive than workplace drug tests.

The medical studies selected for this article are conducted by highly reputable scientific organizations.

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

Study Results

None of the study participants taking the hemp seed oil capsules (aka cannabis Sativa oil) failed the short term drug test or long term drug test in this study. (1)

 

drug screening results

4.6% of urine samples showed trace amounts of THC from hemp seed oil. The trace amounts of THC were far below the level that causes a positive drug test. tell a friend

Summary

It is widely believed that consuming hemp seed oil will not cause you to fail a drug test…but is that true?  New research has the answer. (2)

Background

  • Many people use hemp seed oil for medicinal and cosmetic purposes
  • Although hemp and marijuana are the same species of cannabis Sativa plant, each plant has different chemical properties.
  • The difference between marijuana and cannabis Sativa hemp is determined by the total amount of the intoxicating compound THC found in a specific strain or even an individual plant. (3)

Differences between cannabis Sativa hemp and marijuana:

 

  • Both hemp and marijuana are types of Cannabis plants.
  • If a cannabis plant produces a lot of THC (more than 0.3%) then it’s considered a marijuana plant.
  • If a cannabis plant produces no THC (or “virtually” none), then it’s considered a hemp plant.
  • Marijuana plants generally produce between 5% and 30% THC content.
  • By law, hemp plants produce less than 0.3% THC content.
  • Cannabis growers breed their plants to either produce high levels of THC (marijuana) or low levels of THC (medicinal hemp) depending on the final market for their product.
  • Hemp is bred to have high levels of non-intoxicating cannabinoids like CBD. (4)

Legal Definition of Hemp

The legal definition of hemp is really simple. If a cannabis plant has less than 0.3% THC, then it is legal federally and considered hemp.

Quality hemp seed oil comes exclusively from hemp plants that were bred to have very low to virtually no THC content.

Hemp Seed Oil Benefits

Hemp Seed Oil is used for pain relief, anxiety relief, cosmetic reasons, and as a dietary supplement. (5)

Drug Testing Process

  • Researchers in Korea drug tested the urine of 64 participants to see if hemp seed oil capsules would cause a failed drug test.
  • Researchers tested the first urine samples after 1 week and continued collected urine samples from the participants for the next 12 weeks.  Study participants continued taking hemp seed oil capsules daily throughout the 12 week collection period.
  • At the end of the 12 weeks, researchers tested all samples. (6)
  • The lab equipment used was significantly more sensitive than what is employed in commercial drug tests.

Conclusion

In this long-term study, only two urine samples showed trace amounts of THC but the trace readings were substantially below the level at which they would trigger a failed drug test. (7)
