8.2 Analytical Aspects of Narcotic Drugs and Psychotropic Substances(Preliminary Testing, Identification, Confirmation and Interpretation of Results)

The analytical's ladder (the U7 discipline applied):1. The preliminary (the field-and-lab screening): the colour tests (the Marquis — the purple of the opiates-and-amphetamines; the Duquenois-Levine — the cannabis; the cobalt thiocyanate — the cocaine); the field kits (the roadside-and-raids' instant).2. The identification: the TLC (the spot's comparison); the microscopy (the cannabis's botany — the cystolithic hairs).3. The confirmation: the GC-MS (the molecular fingerprint — the court's standard); the HPLC- and-FTIR (the complementary instruments).4. The interpretation: the substance's identity (the schedule's matching — the offence's classification); the purity-and-adulterants (the trafficking's faces); the quantitative's reporting (U8.3).
