DRUG TESTING PROTOCOL .uk

Urine testing often misses recent use and may not detect until 6-8 hours after use but where metabolites are excreted, will tend to detect up to 3 days. (Long term, high level use of cannabis or benzodiazepines has been reported to remain detectable for several weeks in urine). Table 2 gives a comparative guide to detection windows in OFT vs urine. ................
