THC in CBD products: what the legal limit means and where to check it
Every full-spectrum hemp product contains traces of THC. That is not a defect; it is what “whole plant extract” means. The questions worth asking are how much, whether it is under the legal limit, and where you can check it. This article answers those three without hedging.
The legal limits
EU rules allow industrial hemp varieties with up to 0.3 % THC in the field. For finished products, several member states apply their own limits; Slovenia, where we grow and fill, applies 0.2 %. Whatever the limit in your country, the proof is the same: a laboratory analysis of the batch, not a sentence on the label.
How much THC is actually in our products
Batch 0826 (use by 12/2027) measures ≤ 0.08 % THC – less than half the Slovenian limit. In practice:
| Product | Volume | THC at 0.08 % (maximum) |
|---|---|---|
| 10 ml drops (10 %, 20 %) | 10 ml | up to 8 mg per bottle, up to 0.04 mg per drop |
| 15 ml drops XXL (5 %) | 15 ml | up to 12 mg per bottle |
| 5 ml resin (30 %, 50 %) | 5 ml | up to 4 mg per syringe, up to 0.4 mg per 0.1 ml |
These are upper bounds (0.08 % of volume, rounded up). The actual figure for your batch is on the COA and may be lower.
Why full spectrum contains THC at all
A full-spectrum extract keeps all the plant’s cannabinoids – CBD, CBG, CBC, CBN and traces of THC – plus terpenes. The industrial hemp we grow around Trstenik is a low-THC variety, so the traces are small but present. A product with no THC at all is only possible from an isolate (pure CBD) or a broad-spectrum extract with THC removed. We make full spectrum and say so. More in Hemp extracts explained.
Where to check THC on the COA
- Open the product page and the Certificates tab.
- Find the batch number printed on your pack (e.g. 0826).
- In the cannabinoid table, look for the Δ9-THC row (sometimes also THCA and “Total THC”). Values are in % or mg/g; 0.08 % = 0.8 mg/g.
- Check the laboratory and date: our batches are tested by Institut für Hanfanalytik, Vienna, by HPLC according to the European Pharmacopoeia.

Drug tests
We cannot answer this for you. Tests differ in sensitivity, and the result depends on amount, frequency and the individual. What we can state is the fact: our products contain traces of THC (≤ 0.08 % in batch 0826). If you are subject to testing, ask the testing body before use or choose an isolate product.
Driving
No legal advice here either. Driving under the influence of controlled substances is prohibited regardless of source; whether traces from a full-spectrum product can affect a roadside test depends on the test and the person. The exact content of your batch is on the COA – the only figure you can verify yourself.
What to check with any seller
- COA for the exact batch, not a generic certificate.
- A THC row on the COA, not just “THC < 0.2 %" on the label.
- Full spectrum, broad spectrum or isolate – it must be stated.
- Which laboratory tested it and when.

FAQ
Are CBD drops with 0.2 % THC legal?
In Slovenia, products from industrial hemp with up to 0.2 % THC are permitted; other EU countries apply their own limits. The content must be verifiable on the batch analysis.
How much THC is in 50 % CBD resin?
Batch 0826: at most 0.08 %, which is at most 4 mg per 5 ml syringe. The exact value is on the COA in the Certificates tab.
Do you sell THC-free products?
No. All our cannabinoid products are full spectrum and contain traces of THC below the legal limit. Our hemp seed oil (250 ml) contains no cannabinoids at all.
Why does the label say “< 0.2 %" and not an exact figure?
The label covers all batches of a product; the exact value differs from batch to batch. That is why each batch has its own COA.
