You may have been redirected from unodc.org/tox as we will soon launch a new combined Early Warning Advisory portal with enhanced features.


The UNODC Early Warning Advisory (EWA) Tox-Portal collects, analyses and shares data on toxicology and harm related to the use of NPS at a global level in collaboration with The International Association of Forensic Toxicologists (TIAFT) and other partners. Its objective is to enhance the information available on toxicology and adverse health consequences of NPS worldwide based on high quality information, as NPS continue to be a global threat and their use has been linked to a number of hospital emergencies and fatalities.

Aggregate toxicology case information can still be accessed via the Tox-Dashboard for registered users (weblink was communicated via email to registered EWA Tox-Portal users). Confidential and sensitive data, such as the age, gender and specific location details (e.g. city or state) are not circulated to, published or shared with any third parties or other users. For additional individual case data, please contact unodc-ewa@un.org with any questions. The terms of use of the UNODC Tox-Portal are available here.

Toxicology data is collected from forensic toxicology laboratories, through specific data collection exercises, ad hoc submissions and information from appropriate scientific literature.

The information within EWA contributes to the identification of the most persistent, prevalent, and harmful NPS which pose the greatest threat to public health, thus, informing the prioritisation and scientific review of substances for scheduling under the international drug control convention, as well as legislative responses at the national level.

The evidence of harm related to NPS use is complicated by a scarcity of data on the pharmacology and toxicology of NPS. The UNODC Tox-Portal was developed and launched pursuant to the 2016 United Nations General Assembly Special Session on the World Drug Problem recommendation to prioritise the most harmful, persistent, and prevalent NPS for international action. Following this decision, the Commission on Narcotic Drugs passed resolution 60/4 entitled “Preventing and responding to the adverse health consequences and risks associated with the use of new psychoactive substances.”
