Very strong THCX products, lab-tested batch by batch: 0.0% THC (delta-9) detected. An intense experience with no trace of THC at all.


In short: GBZ420's THCX 0.0% THC products are THCX resins and concentrates with every batch lab-tested: no THC (delta-9) is detected, so a THC saliva test is negative. They are still very strong. They are for adults only and must never be used before driving.
THCX is a new-generation cannabinoid whose effects are described as much closer to THC than to CBD. A "THCX 0.0% THC" product combines two things: a very strong THCX formulation, and a complete absence of delta-9 THC, verified by lab analysis on every batch.
In this selection, we only keep products whose analysis shows 0.0% THC. A product that fails this check does not make it into the category.
This selection is for adults used to strong products who want no trace of THC in what they consume. On every product page, the strength gauge reads "Very strong". If you are new to THCX, start with a very small amount and wait until you feel the effects before taking more.
| Criterion | THCX 0.0% THC | CBD | THC |
|---|---|---|---|
| Delta-9 THC | 0.0% by analysis | Under 0.3% in France | Present, banned in France |
| Felt strength | Very strong | Low, non-psychoactive | Strong |
| THC saliva test | Negative | THC traces possible | Positive |
| Driving after use | Forbidden as a precaution: very strong effect | Not recommended | Forbidden |
Saliva tests look for THC, the cannabis molecule classified as a narcotic in France. Our THCX products are guaranteed 0.0% THC, so a THC saliva test is negative. That is what sets this range apart from CBD products, which can contain traces of THC.
This is not an invitation to cheat or to drive. THCX is very potent: it lowers alertness, slows reflexes and impairs judgement. Driving under the influence of a product that impairs your abilities is dangerous for you and others, and exposes you to prosecution. After use, do not drive for the rest of the day. GBZ420 accepts no liability for any use contrary to these recommendations or to the law.
Resin for a traditional texture, crumble for an easy-to-dose concentrate.
