LAW5510 Forensic Science — Unit 8: Narcotic Drugs and Psychotropic Substances

Unit 8: Narcotic Drugs and Psychotropic Substances

8.1 Introduction and Classification of Narcotic Drugs

The regime’s law: the Narcotic Drugs (Control) Act 2033 (the Nepal statute — the LAW5508 course’s face) + the international conventions (the 1961 Single Convention, the 1971 Psychotropic Convention, the 1988 Trafficking Convention). The classification (the exam’s frame):

1. The narcotics proper (the opioids — the opium, morphine, heroin; the coca-cocaine line).
2. The cannabis group (the ganja, charas, hashish — the plant’s products).
3. The depressants (the sedatives, the benzodiazepines).
4. The stimulants (the amphetamines, the methamphetamine’s rise).
5. The hallucinogens (the LSD, the psilocybin).
6. The new psychoactive substances (the NPS — the synthetic’s innovation race against the schedules).
   The schedules’ logic (the medical-use-vs-abuse-potential grading — the control’s levels).

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).

8.3 Significance of Quantitative Estimation of Heroin Narcotic Drugs on the Legal Aspect

The quantitative’s legal weight: the offence’s grading (the quantity-based sentences — the small-vs-commercial quantities’ regimes; the drug court’s-and-prosecution’s charging); the Nepal Act’s quantity tiers (the possession’s-and-trafficking’s scales — the Act’s schedules); the purity’s questions (the cutting agents — the pure-drug-equivalent debates); the penalty’s proportionality (the quantity’s mitigation-and-aggravation).
