Novel Psychoactive Substance (NPS)
Definition
A substance designed to mimic the effects of a controlled drug while falling outside the definition of any currently scheduled substance; identified by the EMCDDA through the EU Early Warning System and requiring ENFSI DWG laboratories to develop new analytical methods often without an existing certified reference material.
- International control gap
- Not scheduled under the Single Convention 1961, the 1971 Convention on Psychotropic Substances, or the 1988 UN Convention on drug trafficking.
- Tracking authority
- EMCDDA monitors NPS through the EU Early Warning System and tracks over 1,100 as of 2023.
- Core challenge
- Forensic labs lack certified reference materials for most NPS, requiring rapid method development.
Common questions
What makes a substance a novel psychoactive substance?+
An NPS has psychoactive properties but is not controlled by international drug conventions like the Single Convention 1961 or the 1971 Convention on Psychotropic Substances. Manufacturers design NPS to mimic the effects of controlled drugs while technically falling outside existing legal definitions.
Why are NPS a challenge for forensic labs?+
Forensic labs must develop new analytical methods to identify and quantify NPS, often without having a certified reference material available. New substances emerge faster than labs can establish standardized testing protocols.
How many novel psychoactive substances exist?+
The EMCDDA (European Monitoring Centre for Drugs and Drug Addiction) tracked over 1,100 NPS as of 2023. The actual number continues to grow as new compounds are synthesized.
