How to Verify CBD Has No THC | Pop's Cannabis

To verify a CBD product has no THC, read the third-party lab test. The test is called a Certificate of Analysis (COA). The COA must list THC results. The result must say "not detected" (ND) or be below the limit of quantification (LOQ). The LOQ must be low enough to confirm zero THC.

What "no THC" means

THC is tetrahydrocannabinol. CBD is cannabidiol. Both are cannabinoids. Hemp is cannabis with less than 0.3% delta-9 THC by dry weight. This limit is in the 2018 Farm Bill. A product can say "THC-free" but still have trace THC. Trace amounts are below 0.3%. To claim zero THC, the lab must find no THC at a low LOQ.

Step 1: Find the COA

Look on the product label. Many brands put a QR code on the package. Scan the QR code. The code should lead to a lab test. If there is no QR code, go to the brand's website. Search for the batch number. The batch number is on the package. The COA must match the batch number.

Step 2: Check the lab

The lab must be third-party. The lab must not be owned by the brand. Look for the lab's name. Look for the lab's accreditation. ISO 17025 is the standard. A lab with ISO 17025 meets quality rules. Some labs are not accredited. Avoid those tests.

Step 3: Read the THC panel

The COA has a table. The table lists cannabinoids. Look for delta-9 THC. Look for delta-8 THC. Look for THCA. THCA turns into THC when heated. Look for total THC. Total THC equals delta-9 THC plus THCA times 0.877. Some labs report total THC. Others report only delta-9 THC. Read the method.

Step 4: Check the LOQ

The LOQ is the lowest amount the lab can measure. If the LOQ is 0.1%, the lab cannot detect 0.05%. A result of "not detected" at LOQ 0.1% means the product may have up to 0.1% THC. For zero THC, the LOQ must be 0.01% or lower. Some labs use LOQ of 0.001%. Check the number.

Step 5: Check the batch number

The batch number on the COA must match the package. If the numbers do not match, the test is not for that product. Some brands use one COA for many batches. That is not valid. Each batch must have its own test.

Step 6: Home tests

Home test kits exist. They use color changes. They do not measure THC at low levels. They can give false results. Do not rely on home tests. A lab test is the only way to verify zero THC.

Limits of testing

No test can prove zero THC with 100% certainty. Every test has a detection limit. A result of "not detected" means the lab found no THC above the LOQ. The product may have THC below the LOQ. For most people, trace amounts below LOQ are not active. But drug tests may detect THC at low levels. If you need zero THC for a drug test, choose a product with a COA that shows "not detected" at LOQ 0.001% or lower.

Ask the brand for the COA. If they do not provide it, do not buy the product.
