Drug-test detection window simulator
Reported THC detection windows in saliva, urine and blood, by product type and consumption frequency.
Product type
The spectrum is on the label and the certificate of analysis. Screenings only look for residual THC.
Consumption frequency
Reported THC detection windows
These ranges describe the residual THC of a compliant product (≤ 0.3 %), not cannabis use. A highly sensitive test can react outside these windows.
Method and limits
French roadside and workplace screenings target Δ⁹-THC and its metabolites, never CBD itself. A compliant full-spectrum product may carry up to 0.3 % THC; consumed repeatedly, that residue can accumulate in fat tissue and stay detectable.
The windows shown are ranges reported by toxicology reviews of THC pharmacokinetics. Metabolism, body fat, dose and the test’s cut-off all move these bounds. Background reading: our saliva-test guide and how long CBD stays in the body.
