"Non-THC" on a CBD label is a statement about a laboratory's detection limit, not about zero. It means a lab tested the batch, looked for THC, and reported none above the lowest concentration its method can reliably measure. A different lab with a lower reporting limit might report a small number. That distinction matters if you are drug tested at work, and almost no label explains it.
"Non-detect" is a measurement, not an absence
Cannabinoid testing labs report two thresholds. The limit of detection is the smallest amount an instrument can tell apart from background noise. The limit of quantitation is the smallest amount it can put an actual number on with acceptable accuracy. A result printed as "ND", "<LOQ" or "none detected" means the analyte fell below one of those thresholds for that method, that sample and that lab.
So the honest reading of a non-detect THC result is: whatever THC is present, if any, is smaller than this lab could measure. That is a genuinely useful piece of information. It is not the same sentence as "there is no THC in this product," and a brand that tells you otherwise is overselling its own paperwork.
The legal number people confuse this with
The 2018 Farm Bill defines hemp at 7 U.S.C. § 1639o as Cannabis sativa L. and its derivatives "with a delta-9 tetrahydrocannabinol concentration of not more than 0.3 percent on a dry weight basis." Two things follow that people routinely get wrong:
- 0.3% is a ceiling for legal hemp, not a promise about any particular product. A compliant full spectrum product can contain measurable THC and still be hemp.
- 0.3% is a percentage by weight, not a dose. It tells you nothing on its own about milligrams per gummy or per millilitre. For that you have to read the product's own figures.
Which Canna River products are sold as Non-THC
Canna River splits nearly every product into two versions: Broad Spectrum (Non-THC) and Full Spectrum (Contains THC). Some products are only made one way.
| Product | Versions offered | Labeled THC in the Full Spectrum version |
|---|---|---|
| Classic Tincture (15, 30, 60, 120 mL) | Broad and Full Spectrum | 2 mg delta-9 THC per 1 mL |
| Calm, CBD + CBN and CBD + CBG tinctures, 60 mL | Broad and Full Spectrum | 2 mg delta-9 THC per 1 mL |
| All four Ultra tinctures, 120 mL | Broad and Full Spectrum | 2.5 mg delta-9 THC per 1 mL |
| Classic Gummies, Calm Gummies, CBD + CBN and CBD + CBG gummies | Broad and Full Spectrum | 3 mg delta-9 THC per gummy |
| All four softgels | Broad and Full Spectrum | 2 mg delta-9 THC per softgel |
| All four Ultra gummies | Broad Spectrum only | Not offered |
| Pet tincture and pet treats | Broad Spectrum only | Not offered |
| Body Balm and Body Lotion | Broad Spectrum only | Not offered |
If you are specifically avoiding THC, the version is the thing to check, not the product name. The same gummy in the same flavor at the same price exists in both versions, and the only way to tell them apart on the site is the Broad Spectrum / Full Spectrum selector.
What a drug test is actually measuring
Federal workplace urine testing does not look for THC. It looks for a metabolite, delta-9-tetrahydrocannabinol-9-carboxylic acid, abbreviated THCA or Δ9THCC. The cutoffs are set in regulation at 49 CFR § 40.85:
| Test | Analyte | Cutoff |
|---|---|---|
| Initial (immunoassay) | Marijuana metabolite (THCA) | 50 ng/mL |
| Confirmatory (GC/MS or equivalent) | THCA | 15 ng/mL |
A result below the cutoff is reported negative; at or above it, the sample goes to confirmation, and a confirmatory result at or above 15 ng/mL is a confirmed positive. The same two numbers appear in the HHS drug testing panel that SAMHSA publishes in the Federal Register.
Canna River's own site disclaimer is blunt about where that leaves broad spectrum products: "The products on this site may cause you to fail a drug test. Even broad spectrum products considered non-THC may cause you to fail a drug test." That is the correct thing for any hemp company to say. Nobody can test your body chemistry, your dose, your frequency of use and your employer's lab in advance.
Frequently asked questions
Does Broad Spectrum mean zero THC?
No. It means the THC was removed to below the testing lab's reporting limit. Canna River's labeling describes broad spectrum extract as having "non detectable THC levels," which is the accurate phrasing.
Is CBD isolate more reliably non-THC than broad spectrum?
Both are described as non-detect. Isolate is a single purified cannabinoid, so there is less for other compounds to hide in, but the claim still rests on the same kind of lab report. Canna River's gummies list both Broad Spectrum Hemp Distillate and CBD Isolate as ingredients.
How do I check the THC result for my own batch?
Find the batch code on your package and look it up in the COA library. The report for that batch shows the cannabinoid panel, including THC. See Is Canna River CBD Lab Tested? for how the reports are organized.
If a product is legal hemp, can it still contain THC?
Yes. The federal definition permits up to 0.3 percent delta-9 THC by dry weight. Canna River's Full Spectrum products say so on the label: "Contains THC," with the per-serving amount stated.
Are topicals a way around a drug test?
Canna River does not make that claim and neither will we. The balm and lotion are Broad Spectrum only, and the same site-wide disclaimer applies to them.
