K-Hole

K-Hole

K-Hole (Ketamin-Loch) ist ein Szeneausdruck für eine Dosis Ketamin, die zu einer circa 30-minütigen Dissoziation führt. Hierbei können Ataxie, Dysarthrie, muskuläre Hypertonie und Myoklonie auftreten.[1] Äußerlich gleicht der Zustand häufig einer Bewusstlosigkeit. Das subjektive Erleben eines K-Hole verläuft unterschiedlich, berichtet wird von akustischen Halluzinationen, Reisen durch einen dunklen Tunnel, Visionen und Nahtod-Erfahrungen.[2] Ein K-Hole tritt vor allem bei der gleichzeitigen Einnahme von Ketamin mit Sedativa, beispielsweise Alkohol, auf.[3] Das K-Hole kann nicht nur unerwünschte Überdosierung, sondern auch das Ziel des Ketaminkonsums sein.[4]
