K.O. drops and excessive alcohol consumption have similar symptoms. However, dizziness, nausea or unconsciousness occur more suddenly with knockout drops. Knockout drops are usually taken unnoticed, as the perpetrators mix them into a glass or bottle at a party, public viewing or during an event, for example. They often lead to unconsciousness - also known as "knockout" - which is why the drops are colloquially referred to as such.

Effect

Since the knockout drops are colorless and odorless, unsuspecting victims usually only notice that something is wrong with them after the effect begins - far too late. The first symptoms, such as dizziness or a sudden high, can occur after just ten to twenty minutes. Victims quickly experience nausea, drowsiness and often fall unconscious. An overdose can even result in death due to respiratory paralysis.

The strength of the effect may also depend on how much alcohol was consumed beforehand.

Symptoms

• Disinhibition
• Difficulty of perception, drowsiness
• Fatigue
• Sudden unconsciousness
• Film loss, memory lapses

Detectability

K.O. drops can only be detected in the blood or urine for a few hours. If you suspect that the substance has been administered unnoticed, you should therefore consult a doctor or go to the emergency room immediately.

How to protect yourself from knockout drops

• Don't accept drinks from strangers.
• Always keep an eye on your glass/bottle.
• Seek help from friends, acquaintances or bar staff.
• If you are unsure: Leave your drink undrunk.

If you have become a victim

• If necessary, call the emergency services or have friends or relatives accompany you to the emergency room.
• In addition, you should report any suspected cases to the police.
