Athletes: WADA Compliance

If you compete under the World Anti-Doping Code, understanding WADA CBD rules is essential. Cannabidiol (CBD) itself is not prohibited by WADA, but many other cannabinoids — including THC — are banned in-competition. This page explains the essentials so athletes can minimize drug-testing risk while considering THC-free options.

Because most CBD products come from hemp, trace THC or other cannabinoids can be present. To reduce risk, choose THC-free products and verify third-party Certificates of Analysis (COAs) that clearly show non-detect THC within the lab’s limit of quantitation (LOQ).

What WADA Says About CBD and Cannabinoids

CBD (cannabidiol) is not prohibited by WADA. See the current WADA Prohibited List.
All other cannabinoids (natural or synthetic) are prohibited in-competition. This includes delta-9 THC, THCA, delta-8 THC, delta-10 THC, THCV, THCP, and synthetic cannabinoid receptor agonists.
THC is prohibited in-competition, with a urine decision limit typically tied to 11-nor-9-carboxy-THC (carboxy-THC). WADA’s threshold for carboxy-THC is 150 ng/mL.
Out-of-competition rules can differ, but in-competition samples can detect residual metabolites from earlier use. Always check your International Federation or National Anti-Doping Organization (e.g., USADA) for exact definitions and timing of “in-competition.”

CBD for Athletes: Drug Test Basics

Anti-doping tests may occur at events or elsewhere. “In-competition” is often defined as starting the evening or midnight before competition through the end of doping control; confirm your sport’s rule. Even small amounts of THC from contaminated products could accumulate and lead to an Adverse Analytical Finding during this window.

Minimizing Risk With THC-Free CBD

Choose the right product type

Prefer CBD isolate labeled “THC-free.” Broad-spectrum may still contain trace minor cannabinoids; full-spectrum is more likely to include THC and is not recommended for tested athletes.
Avoid products mentioning delta-8, delta-10, THC-O, HHC, or other cannabinoid analogs — these are prohibited in-competition.

Read the COA carefully

Look for a batch-specific COA that matches your product’s lot number and date.
Confirm “non-detect (ND)” or “0.000%” for delta-9 THC and THCA, and ideally for delta-8/delta-10 THC, THCV, THCP, and CBN. The COA should show the lab’s LOQ for each analyte.
Prefer COAs from ISO/IEC 17025–accredited labs. Ensure cannabinoid potency and residual solvent/heavy metal tests are included.
Be wary of COAs that omit THC, lack LOQ values, or don’t match your exact batch.

Understand LOQ and “THC-free”

LOQ (limit of quantitation) is the lowest level a lab can reliably measure. “THC-free” typically means THC is below the LOQ and appears as ND on the COA.
Even with ND results, mislabeled products or inconsistent manufacturing can occur. Stick to reputable brands and keep documentation.

Use and timing practices

Avoid starting any new product close to competition. If you use CBD, consider a consistent product with reliable COAs.
Discuss timing and product choice with your team physician or sports dietitian. Individual risk tolerance and testing frequency vary.

Red Flags to Avoid

“Full-spectrum” hemp extracts for tested athletes.
Any mention of delta-8/delta-10 THC, THCP, THC-O, or “legal highs.”
COAs that list measurable THC without ND status or that lack LOQ disclosure.
Unverifiable online COAs, mismatched batch numbers, or no third-party testing.

Frequently Asked Questions

Is CBD allowed by WADA?

Yes. CBD is not prohibited by WADA. However, many other cannabinoids — including THC — are prohibited in-competition. Choose THC-free CBD and verify COAs.

Can CBD cause a positive drug test?

Pure CBD should not trigger a cannabinoid violation, but contaminated or mislabeled products can. Use THC-free products with COAs showing ND for THC and related isomers.

What THC threshold applies in-competition?

WADA uses a decision limit related to 11-nor-9-carboxy-THC (carboxy-THC) of 150 ng/mL in urine. Residual metabolites from earlier use can still be detected.

Which form of CBD is lowest risk?

CBD isolate with a robust, batch-specific COA showing ND for THC (and related isomers) is generally the lowest-risk option for tested athletes.

What should a trustworthy COA show?

Batch number, test date, ISO/IEC 17025 accreditation, analyte list with ND/LOQ values for THC/THCA/delta-8/delta-10/THCV/THCP/CBN, and potency consistency.

Summary

Under WADA rules, CBD is not prohibited, but THC and most other cannabinoids are banned in-competition. To reduce drug-testing risk, athletes should favor CBD isolate, verify batch-matched COAs with ND results and clear LOQs for THC and related isomers, avoid products advertising alternative THC forms, and keep thorough documentation. Always check the current Prohibited List and your sport’s specific policies before using any supplement.
