In April 2021, we tested a number of substances of particular health concern. In addition to some ecstasy tablets, some of which contained very high doses, a sample submitted for analysis as cocaine contained the new psychoactive substance N-ethylhexedrone detected. A sample submitted as mephedrone (4-MMC) did not contain the expected substance, but rather Clephedrone (4-CMC). Please refer to the appendix for details.

In the following, all samples that have been taken since the last warnings to date by checkit! analysed and classified as high-dose, unexpected or of particular health concern. Current warnings week 17- 2021
