ABSTRACT
Forensic toxicologists work with pathologists, medical examiners, and coroners in helping to establish the role of alcohol, drugs, and poisons in the cause of death. For screening of benzodiazepam drugs viz. alprazolam, chlorazepam, diazepam, lorazepam, and nitrazepam, thin-layer chromatography is used. Forensic toxicologists perform analysis of drugs and alcohol in biological samples—typically blood and urine, but increasingly in other matrices such as oral fluid and hair—to determine the timing, extent, and impairment resulting from different patterns of drug and alcohol use. Liquor is normally known as a mixture of water and alcohol. The liquor is examined for quality control/duplicate samples, which are being sold in the market in which the examination is carried out for parameters other than alcohol contents. Country-made liquor is an alcoholic product, usually prepared from fermentation of carbohydrates present in cereals, jaggery, fruits, mahua, palm, molasses, and so on.
