Report Illicit Drug Reactions

The Reporting Illicit Drug Reactions (RIDR) website is a one year UK-wide pilot to establish an online data collecting system for adverse reactions and harms related to New Psychoactive Substances (NPS) as well as other illegal drugs.

The project is being co-ordinated by Public Health England and delivered by the Medicines and Healthcare products Regulatory Agency

The aim is to help improve clinical understanding of emerging drug harms and to reduce the length of time between the emergence of drug related health harm and the dissemination of effective treatment responses.

The web-based reporting form allows information to be submitted for on-going collection and analysis. It can be used by front line health workers who have contact with NPS (or other drug) users.

Information on how to report reactions using the system, as well as other relevant resources, is available via the following link:
