Typical substances used in drink spiking
GHB or GBL
GHB and GBL are colorless liquids and are among the most common date rape drugs. Drowsiness and loss of consciousness occur within 10 to 30 minutes. Because they are only detectable for a short time, medical help should be sought immediately if GHB or GBL is suspected.
Benzodiazepines
Benzodiazepines such as Rohypnol are tablets or drops with a sedative effect. They take effect after 15–30 minutes and cause drowsiness, memory lapses, and disorientation that can last for several hours.
Ketamine
Ketamine is an anesthetic available in powder or liquid form. It takes effect within minutes, can cause hallucinations and immobility, and in most cases lasts for 1–2 hours.
Facts about the problem
  Knockout drops are an invisible but real threat. Even small amounts are enough to render people defenseless – with serious consequences for health and safety.
  Many incidents remain hidden – out of fear, shame, or lack of evidence. The number of unreported cases is correspondingly high, which often makes the extent of the problem seem underestimated.
  The effects extend far beyond the moment. In addition to health risks, such incidents often leave deep psychological scars and undermine confidence in a safe outcome.
