Alcohol‑Related Offences & Forensic Analysis

Ethyl alcohol is a drug of addiction linked to significant morbidity and mortality. To curb alcohol‑related crimes, consumption without a valid permit and unauthorized possession, sale, export, or import of alcohol‑containing beverages are offences under the Bombay Prohibition Act. This division examines seized liquors, denatured spirits, and biological samples, and performs quantitative alcohol assay using a Densitometer along with case‑appropriate chemistry.

Division Scope

Assay of excise samples, illicit liquor detection, denatured spirit tampering checks, and blood alcohol analysis for legal cases.
