About this mock

UGC-NET Forensic Science Unit IV drill on the narcotics and opiates analytical workflow at the application band. Items step through the natural, semi-synthetic and fully synthetic opioid classification with worked examples (morphine, codeine, thebaine, papaverine, noscapine, heroin, oxycodone, hydromorphone, buprenorphine, methadone, fentanyl, carfentanil, tramadol, pethidine, naltrexone), mu-kappa-delta receptor pharmacology, naloxone reversal, the heroin to 6-MAM to morphine metabolic chain that drives the poppy-seed defence in urinalysis, Marquis-Mecke-Mandelin presumptive sequence, Dragendorff TLC visualisation, microcrystal tests, HPLC-DAD reference-standard matching, LC-MS/MS MRM confirmation, GC-MS minor-alkaloid heroin profiling, SAMHSA cut-offs, and the Indian legal framework under NDPS Section 52A with Union of India v. Mohanlal (2016) sampling and Tofan Singh v. State of Tamil Nadu (2020) Section 67 doctrine. Indian context covers the Mizoram and Manipur transit corridor and dark-net cryptomarket convergence.
