ENFSI Drugs Working Group (DWG)
Definition
European Network of Forensic Science Institutes Drugs Working Group. Publishes best-practice manuals for drug analysis aligned with SWGDRUG tiering principles, operates an External Quality Assessment (EQA) proficiency testing scheme for EU drug laboratories, and provides harmonised guidance on quantification, measurement uncertainty, and reporting.
- Member coverage
- 35 EU and associated countries
- Key programs
- Best-practice manuals, External Quality Assessment (EQA) proficiency testing, NPS identification guidance
- Guided standards
- Aligned with SWGDRUG tiering principles for drug analysis
Common questions
What does ENFSI's Drugs Working Group do?+
It coordinates drug analysis standards and best practices across forensic laboratories in 35 EU and associated countries. The group publishes guidance manuals, runs proficiency testing programs, and helps labs stay aligned on how to identify and analyze drugs consistently.
How does the DWG help ensure quality in drug testing labs?+
They operate an External Quality Assessment (EQA) proficiency testing scheme that lets EU drug laboratories verify their methods are working correctly. They also publish tiered identification protocols and guidance on measurement uncertainty and reporting, so results are trustworthy across borders.
Does the DWG work with novel psychoactive substances (NPS)?+
Yes. The working group provides harmonised guidance on identifying NPS alongside traditional drugs, which is critical as new synthetic compounds emerge constantly in forensic casework.
