… estimated street value…
The Directorate of Criminal Investigations (DCI), primarily through its Anti-Narcotics Unit (ANU), estimates the value of seized narcotic drugs using a structured process centered on quantity, type, and prevailing street prices in the illicit market.
The process typically begins with the physical weighing of the recovered substances to establish their quantity (e.g., in grams or kilograms). This step is often conducted in the presence of relevant parties as per legal requirements and is documented via a weighing certificate.
Next, the approximate value is calculated based on the prevailing street value (market price) of the specific drug in Kenya’s illicit markets. This intelligence-driven figure reflects current prices per gram or kilogram, drawn from ongoing monitoring of illegal drug trade dynamics, recent seizures, and informant data.
Forensic analysis by the Government Chemist (or a designated analyst) follows to confirm the drug type, identity, and purity level. This scientific verification ensures accuracy and supports evidentiary requirements under the Narcotic Drugs and Psychotropic Substances (Control) Act.
This estimated street value is routinely cited in DCI press statements, court proceedings, and media releases to reflect the scale of the illicit trade and potential penalties (which may consider market value under the Act).
The approach ensures valuations are evidence-based, transparent, and aligned with both investigative and prosecutorial needs.
