WEDINOS (an acronym for Welsh Emerging Drugs and Identification of Novel Substances) is a public health laboratory in Cardiff, Wales devoted to drug checking and epidemiological surveillance of recreational drugs and prescription drugs obtained from unsanctioned sources. It is the only fixed-site facility in the United Kingdom devoted to this task. [1] [2] It was established in 2013, and is funded by Public Health Wales. [1] [3]
Although based and funded in Wales, WEDINOS analyzes samples sent from anywhere in the United Kingdom. [1] [4]
WEDINOS results show high levels of mis-labeling and adulteration of contributed samples of drugs. [5] As of 2025 [update] , WEDINOS data showed that 43% of supposed cannabis samples contained no plant-derived materials, with 38% containing noxious substances. [6]
