Cannabidiol (CBD) has gained popularity for its purported therapeutic benefits, including pain relief, reduced anxiety, and stress management. However, for employees subject to FMCSA drug testing regulations, using CBD products can be risky. Despite its growing popularity, CBD is not regulated, and it may contain trace amounts of THC, which can result in a positive drug test.
In this article, we’ll dive into why CBD is a concern for FMCSA-regulated employees and what FMCSA rules say about handling positive drug test results due to CBD use. The risks are the same for any employee who works in a safety-sensitive position under the regulations of the US Department of Transportation.
What is CBD, and How is It Different from THC?
Cannabidiol (CBD) is a chemical compound derived from the cannabis plant. Unlike THC (Tetrahydrocannabinol), the psychoactive component responsible for the “high” associated with marijuana use, CBD does not produce these effects.
Key Difference:
- CBD: Non-psychoactive, does not induce a
- THC: Psychoactive, responsible for the high when using
However, while CBD itself does not contain THC, CBD products may still have trace amounts of THC, which can pose a risk for individuals subject to FMCSA drug testing regulations.
Why is CBD a Risk for FMCSA-Regulated Employees?
1. Lack of Regulation
CBD products are not regulated by any federal agency, including the Food and Drug Administration (FDA). This means:
- Inconsistent Labeling: CBD products often claim to be “THC-free” but may not accurately disclose their THC content.
- Contamination Risks: Due to lack of regulation, cross-contamination during manufacturing could result in CBD products containing THC.
2. Risk of Testing Positive for THC
Even small amounts of THC in CBD products can accumulate in the body over time, leading to a positive drug test under FMCSA regulations.
- Federal drug tests screen for THC, not CBD
- Any detectable THC at or above the threshold (50 ng/mL for the initial test) will result in a positive test, even if it was unknowingly consumed through CBD.
Using CBD is not a valid excuse for a positive drug test. FMCSA regulations treat any positive THC test as a violation, regardless of the source.
FMCSA Guidance on CBD Use
The FMCSA’s stance is clear:
- Employees in safety-sensitive roles (e.g., commercial drivers) should exercise caution or avoid CBD products altogether.
- Due to the unregulated nature of CBD, there is no guaranteed way to verify that a product is free of THC.
If you test positive for THC, FMCSA regulations dictate immediate removal from safety-sensitive duties. A referral to a Substance Abuse Professional (SAP) is required to begin the return-to-duty process.
Steps to Avoid Risks with CBD
1. Avoid CBD Products
The safest approach for FMCSA-regulated employees is to avoid CBD products entirely to ensure compliance with drug testing regulations.
2. Understand the Risks
Educate yourself about the unregulated nature of CBD products and their potential to contain THC. Be aware that many products labeled “CBD-only” may still contain trace amounts of THC.
3. Consult with Employers or Professionals
If you are considering using CBD, consult with your employer or a legal professional who is familiar with FMCSA drug testing regulations to understand the potential risks and consequences.
Consequences of a THC Positive Test
If you test positive for THC, the consequences are serious:
- Immediate removal from safety-sensitive
- A referral to a SAP for evaluation and completion of a return-to-duty
- The violation will be recorded in the FMCSA Drug and Alcohol Clearinghouse, which may impact future employment opportunities.
While CBD may seem like a harmless wellness product, its unregulated nature makes it a risky choice for FMCSA-regulated employees. Abstaining from CBD use is the safest way to avoid a positive drug test and protect your career.
