Act quickly!


You've hardly had something to drink, but suddenly you feel really bad? Your body is reacting very differently than usual? Regardless of whether you have been drinking alcohol or not, we will take your suspicions seriously!
If you believe that you have been given knockout drops, it is important to act quickly. The time window for detecting knockout drops is very short. Get tested free of charge and confidentially.


  • Do not stay alone!
    Ask friends, staff or other trusted people for help.
  • Don't be afraid to call the police (110)!
    Administering knockout drops is considered dangerous bodily harm and is therefore a criminal offence. Always report the offence if you have been a victim.
  • If you need immediate medical assistance, go immediately to one of the emergency rooms in the city or call an ambulance (112).
    The doctors will check your vital functions and, if suspected, test you for knockout drops. This is done by taking a urine or blood sample.

Important: Get tested as soon as possible! The substances are most detectable in the first urine after administration. The more time passes, the more difficult it becomes to detect knockout drops. The tests are confidetially.
