Strong CBD resin: 14 hashes compared, 14.8 to 20.5%
A "strong" CBD resin comes down to one figure you can check: the percentage of its dominant cannabinoid, CBD or CBG, measured on the batch. On the 14 resins in our catalogue checked on 23 September 2026, the level shown runs from 14.8 to 20.5%, with 0.1 to 0.2% Δ⁹-THC. Before buying a resin far above that range, ask which molecule was measured.
Key takeaways
- You read a resin's strength on the batch analysis; its name and colour say nothing about it.
- In the reference profiles of 14 catalogue resins, the dominant cannabinoid shown runs from 14.8 to 20.5% and Δ⁹-THC from 0.1 to 0.2%.
- The French health agencies ANSES and ANSM issued a warning in June 2025 about CBD products labelled "strong".
- HHC, H4CBD and THCP are narcotics, so a resin containing them is illegal whatever its CBD content.
- In France a website must say whether its customer reviews are checked, and fake reviews are banned.
"Strong": what the word can measure
Resin, or hash, is a pressed mass of trichomes, the tiny glands covering female hemp flowers, once they have been detached from the plant. According to a review published in 2021 in Frontiers in Plant Science, stalked glandular trichomes are the ones that produce the most cannabinoids. Concentrating these glands concentrates the flower's cannabinoids.
The dominant cannabinoid of a legal hemp resin is CBD or CBG. CBG is also non-intoxicating, and the plant makes CBD from it. The only measurable meaning of "strong" is therefore a high percentage of one or the other. Aroma, colour and texture give no clue to that figure; what the shade does indicate is explained in our article on resin colour.
Δ⁹-THC sets a legal limit and says nothing about strength. The French order of 30 December 2021 caps it at 0.30% in hemp, in its extracts and in the products that contain them.
What 14 resins in the catalogue show
The table shows the reference profile displayed on each product page on 23 September 2026. As of 18 October 2026, no laboratory certificate is published on those pages, and a new batch may show different figures.
| Resin | Dominant | Stated content | Second cannabinoid | Δ⁹-THC |
|---|---|---|---|---|
| Strawsift CBG/CBD | CBG | 20.5% | CBD 4.7% | 0.2% |
| Rosift CBG/CBD | CBG | 20.2% | CBD 4.6% | 0.2% |
| Hash CBG 90µ | CBG | 19.3% | CBD 4.2% | 0.1% |
| Afghan Hash CBD/CBG | CBG | 18.5% | CBD 4.0% | 0.2% |
| Rosift | CBG | 18.4% | CBD 3.9% | 0.1% |
| Piatella | CBD | 18.0% | CBG 1.4% | 0.2% |
| Strawsift | CBG | 16.3% | CBD 3.1% | 0.2% |
| Bubble Hash | CBD | 16.3% | CBG 1.5% | 0.2% |
| 120u | CBD | 15.9% | CBG 1.3% | 0.2% |
| Caramelo 120u | CBD | 15.5% | CBG 1.2% | 0.2% |
| Dry Sift 90u | CBD | 15.1% | CBG 1.0% | 0.2% |
| Frozen Hash from the catalogue | CBD | 15.0% | CBG 1.0% | 0.2% |
| Hash 3x filtered | CBD | 14.9% | CBG 1.0% | 0.2% |
| Ice-O-Lator 45u | CBD | 14.8% | CBG 0.9% | 0.2% |
Three things stand out. The most and least concentrated resins are 5.7 points apart, far from double. CBG-dominant resins top the ranking. The method does not determine the content either: the 120u and the 45u, both ice-water hashes, show 15.9 and 14.8%. All of them are listed in the CBD resin and hash category, and our comparison of static, frozen and piatella works out their price per 100 mg of cannabinoid.
Why a very high figure should worry you
A figure well above the others may mean a better resin, or it may conceal a molecule other than CBD. On 19 June 2025, ANSES and ANSM reported an increase in poisonings linked to products sold as CBD, most often due to THC above 0.3% or to synthetic cannabinoids. Their statement adds that particular attention must be paid to products labelled as "strong", which may be even more dangerous.
These molecules are classified as narcotics. ANSM added HHC and two derivatives on 12 June 2023 to the list, followed by H4CBD, THCP and other cannabinoids on 3 June 2024. Any resin containing them is illegal, even at 20% CBD. How H4CBD came to be banned is traced in our article on H4CBD.
Three lines of a lab report answer the question:
- The dominant cannabinoid and its percentage, which must match the figure on the product page.
- Δ⁹-THC, at no more than 0.30%.
- The batch number of the product sold, plus the absence of HHC, H4CBD and THCP where the lab tested for them.
Each line is explained in our guide to the certificate of analysis. The laboratory page describes the methods, and our article on adulterated hashish lists the signs of a tampered resin.
Hard, crumbly or sticky: what texture tells you
"Hard" and "concentrated" answer different questions: one describes firmness, the other content. Texture comes mainly from the separation method, the pressing and the temperature. Cannabinoid content does not set it.
- A dry sift is sieved dry and remains a powder of trichomes until it is pressed.
- An ice-o-lator hash is separated in ice water, dried, then pressed.
- A piatella is an ice-water hash cured in the cold for several weeks.
The warmth of your fingers softens a hard resin and leaves its content unchanged. Stickiness is no sign of higher concentration either. How to temper hash is explained in our article on hash that is too hard or too soft.
Before you buy: analysis first, reviews second
Customer reviews inform you about the service and say nothing about CBD content. Two French texts govern their publication. Article L111-7-2 of the Consumer Code requires any site publishing reviews to state whether and how they are checked, and to date each review. Article L121-4 classes as misleading both the publication of fake reviews and the claim that reviews come from buyers when this has not been checked.
A useful review describes the product: its taste, texture, delivery date, or how it compares with another purchase. A burst of very short reviews posted within a few days tells you little. Our article on CBD reviews covers the reliability criteria.
A very high figure at a very low price is another reason to look at the analysis. When two resins have different contents, compare their price per milligram of cannabinoid, as our guide to hash price per gram suggests.
Frequently asked questions
In our catalogue, checked on 23 September 2026, the dominant cannabinoid shown for 14 resins ranges from 14.8 to 20.5%. For a resin advertised well above that, look for a batch analysis that names the molecule measured and tests for banned cannabinoids.
A higher figure means more cannabinoid per gram and nothing else. A CBD resin is not a medicine, and no health claim is allowed for it.
The difference is the dominant cannabinoid. CBG-dominant resins in our catalogue show 16.3 to 20.5% CBG and 3.1 to 4.7% CBD. The same 0.30% Δ⁹-THC limit applies to both.
It carries a real risk. France's Court of Cassation ruled on 21 June 2023 that permission to sell hemp derivatives under 0.30% THC "has no bearing on the offence of driving after drug use". Even a legal resin contains THC traces that can turn a saliva test positive.
See whether the site explains how it checks its reviews, as the law requires, and whether each one is dated. Give more weight to reviews that describe the product than to generic one-liners.
