Our latest warnings for calendar week 23 are now online!
Between mid- and late May 2026, we tested a range of substances of particular concern to public health. In most of the cathinones submitted for analysis, one or more cathinones other than those expected were detected; these included, in particular, 4-CMC (4-chloromethcathinone). Furthermore, in a sample submitted for analysis as fentanyl, carfentanil – which is many times more potent – was detected alongside two as yet unidentified opioids. A tablet submitted for analysis as ecstasy contained an unknown substance.

Our latest warnings for calendar week 21 are now online!
From early to mid-May 2026, we tested a number of substances of particular concern to public health as part of our stationary and mobile drug-checking services. In a sample supplied as MDMA, the active ingredient 4-CMC was found alongside MDMA. In two tablets submitted as 2C-B, an unknown substance was detected in each, alongside the expected active ingredient. One cocaine sample contained only procaine.

Consumption is never risk-free. If you want to consume despite the risks, you can find out what you need to bear in mind in this article.
- Find out about the substances, their effects and risks
- If you decide to use drugs, make sure you feel comfortable, are in a safe place and are surrounded by people you trust.
- Find out about the least risky way to consume and only use your own consumption utensils
- Use drug checking (e.g. with checkit!)
- Dose low to test the effect and take your time before topping up. You will tolerate less after breaks in consumption.
- Avoid mixed consumption (also with alcohol).
- Take consumption breaks.
- Drink about half a litre of non-alcoholic drinks per hour.
>> Look out for each other! Talk to your friends if one person is not feeling well. <<

Our latest warnings for calendar week 19 are now online!
The warnings show all samples that have been analysed since the last publication of checkit! and classified as high-dose, unexpected or of particular health concern.
At the end of April 2026, we tested a number of substances of particular concern to public health. In a fragment submitted for analysis as ‘ecstasy’, a mixture of MDMA and caffeine was identified instead of the expected MDMA. In a sample submitted for analysis as HHC, the synthetic cannabinoid MDMB-PINACA and an unknown substance were identified, whilst in a hashish sample, the synthetic cannabinoids ADMB-5en-HINACA and ADB-HEXINACA were identified. The majority of samples submitted as 3-MMC or mephedrone (4-MMC) did not contain the expected cathinone, but rather a different cathinone or a mixture of several cathinones, including 4-CMC, N-ethylpentedrone and 4-BEC.
