Psychoactive substances - information for health professionals

Unidentified Substance in Emergency Departments (USED) Programme

The USED programme is a pilot initiative created by ESR (Institute of Environment Science and Research). The intent is to carry out toxicological testing to identify any substances, such as synthetic cannabinoids, present in individuals who present to an emergency department (ED) showing specific symptoms of intoxication.
