Blacklist
List of extra dangerous pills
In addition to issuing nationwide warnings via 'Red Alerts,' the Trimbos Institute maintains a 'blacklist' of pills that carry extra risks; such as those containing high doses of PMMA or other particularly harmful substances.
The list includes only pills that have been submitted for drug checking by the public; other high-risk pills may still be in circulation. Therefore, always have your pill tested.
If your pill appears on this list, do not use it; instead, take it to a drug checking service.
