If your job, your sport or your probation depends on a clean drug test, “THC-free” is the most important phrase on a CBD label. It is also the one most worth double-checking.
Here is what “free THC” really means, what drug tests actually look for, and how to pick a product at our Naples, FL 34119 shop with the least risk.
Drug tests do not look for CBD. They look for THC, or more precisely a THC breakdown product. CBD only becomes a drug-test problem when the product also contains THC. That can happen even with legal hemp CBD, because Florida’s hemp limit is 0.3% total Delta-9 THC, not zero.
So the goal is simple: choose a product whose lab report shows no detectable THC, and confirm it for the exact batch you buy.
Federal workplace urine testing, used for jobs regulated by the US Department of Transportation, measures a THC metabolite. Under the federal drug-testing cutoff rule (49 CFR 40.85):
| Test step | Cutoff for the THC metabolite |
|---|---|
| Initial screening test | 50 ng/mL |
| Confirmation test | 15 ng/mL |
The federal rule lists this metabolite as “THCA”. In drug testing, that refers to THC’s breakdown product, not the THCA cannabinoid found in raw hemp. Private employers may use different panels, so ask yours what it tests for.
Small amounts add up with daily use. In a 2020 clinical trial published in JAMA Psychiatry, adults took a full spectrum, high-CBD extract containing just 0.02% Delta-9 THC, 1 mL three times a day (2020 JAMA Psychiatry trial on urine THC after daily full spectrum CBD). After 4 weeks:
The lesson: if you are tested, a legal full spectrum product is not a safe bet.

You do not have to take a label’s word for it. Florida law requires every hemp extract container to carry a QR code linked to its lab report.

People often search for Smokiez edibles with no THC. A March 2023 lab report from Green Leaf Lab for Smokiez Blue Raspberry CBD Gummiez (250 mg CBD) showed:
| Cannabinoid | Result |
|---|---|
| Total CBD | 3.91 mg/g |
| Delta-9 THC | Below LOQ (0.001%) |
| Total THC | Below LOQ (0.001%) |
That is the kind of result you want to see. Because each batch is different, ask us for the COA of the batch on our shelf before you buy.
Florida allows hemp CBD with up to 0.3% total Delta-9 THC. “Zero THC” is therefore a choice you make as a buyer, not a legal requirement. Look for “isolate” or “broad spectrum” on the label, then confirm “ND” for THC on the batch COA. Florida also limits hemp extract you eat, drink or inhale to buyers 21 and older.
What to skip if you are tested: the Purple Hippo CBD 5000 mg Full Spectrum topical (its lab report shows 0.156% Delta-9 THC), plus our Enjoy hemp syrups and Skybites gummies, which contain hemp-derived Delta-9 THC on purpose.

Standard tests look for a THC metabolite, not CBD. A product with no detectable THC on its batch COA carries the lowest risk. No CBD product can guarantee a negative result, because of batch differences and the risk of mislabeling.
Gummies made with full spectrum extract can contain THC. Gummies made with isolate or broad spectrum extract, with “ND” for THC on the batch COA, are the lower-risk choice.
Broad spectrum CBD has the THC removed while keeping other cannabinoids. It can be THC-free, but confirm “ND” for Delta-9 THC on the batch COA.
Under federal workplace rules (49 CFR 40.85), urine is positive at 50 ng/mL of the THC metabolite on the initial screen, confirmed at 15 ng/mL. Private employers may use different panels.
A March 2023 lab report for Smokiez Blue Raspberry CBD Gummiez (250 mg) measured Delta-9 THC and total THC below 0.001%, the lab’s limit of quantitation. Check the COA for the batch you buy.
