Post ingestion, Δ 9 THC is metabolised into the inactive ingredient Tetrahydrocannabinolic Acid ( THC COOH) Suspected drug drivers are often subjected to a screening test of cannabinoids in saliva A positive result must then be confirmed by the presence of Δ 9 THC in a blood sample by gas chromatography. Quantification of THCA can indicate long term use of the drug. Drug detection limits are set by government laws and vary from country to country The limits in the United Kingdom and Canada is 2 ng/mL whereas in France the limit is 1 ng/ mL
