Will CBD show up on a drug test?

As CBD (Cannabidiol) continues to gain traction for its therapeutic benefits, one question looms large for users: Will CBD show up on a drug test? The answer is a complex one, influenced by various factors such as the type of CBD product used, its purity, and the specifics of the drug test itself. 

Will CBD Show Up On a Drug Test?

Key takeaways

  • CBD itself should not show up on a drug test.
  • The use of certain CBD products could result in a positive test.
  • Legal implications vary depending on local country laws and employer policies.

The basics

  • CBD: A non-psychoactive compound found in cannabis and hemp plants.
  • THC: The psychoactive compound that gets you "high."
  • Drug Test: Primarily screens for THC, not CBD.

The answer

While CBD should not appear on a drug test, the use of certain CBD products could, in theory, lead to a positive result. This is mainly because many CBD products are classified as supplements in many countries and are not regulated for safety and purity.

Factors affecting the test result

  1. Type of CBD product: Full-spectrum CBD products contain up to 0.2% THC, which could lead to a positive result.
  2. Cutoff level of the test: Different tests have different sensitivity levels.
  3. Contamination: Since CBD products are not regulated, contamination with THC may occur.
