Investigating the Illicit Manufacture of Pharmaceutical Drugs in Sri Lanka-A Case Study on the Underworld of Counterfeit Drugs

Abstract

The pharmaceutical drug industry is engaged in the research, development, manufacture and marketing of drugs and medications, which plays a major role in the healthcare industry. The global demand for the pharmaceutical drugs is on the rise, and unfortunately there is a concurrent increase in the illicit production of these drugs worldwide. This surge can be attributed to factors such as high demand, potential for profit, weak regulatory oversight and desire to exploit gaps in the legal market. Despite pharmaceutical drugs are intended for the treatment of medical conditions and pain relief, there is growing trend of illicit drug abusers to misusing these substances. Reports indicate a significant number of unlicensed pharmacies in Sri Lanka, but fewer accounts of illicit manufacturing of pharmaceutical drugs. In April 2023, the Police Narcotic Bureau officers arrested a building in a densely populated area in Colombo, Sri Lanka, suspecting it to be a clandestine laboratory for the production of illicit drugs. Subsequently, the Government Analyst of Sri Lanka was tasked with investigating the suspected clandestine laboratory. A team of forensic analysts from Government Analyst’s Department (GAD) visited the site, scrutinized the location, examined the equipment and chemicals and collected samples for further analysis. Although the clandestine laboratory was abandoned at the time of visit, evidence of machinery used for filling capsules, various chemicals, chemical glassware and other equipment were observed. Preliminary tests for illicit drugs and handheld Raman Spectroscopy testing were conducted at the scene. Gas Chromatography – Mass Spectroscopy (GCMS) was performed on the collected samples in the GAD laboratory. The analysis revealed the samples collected from the clandestine laboratory contained the substances considered pharmaceutical drugs namely, Tramadol, Lidocaine, Niacinamide, Menthol and Chlorpheniramine.
