Focus on the perilous ‘trip’ of K-Land/K-Hole
Ketamine was introduced by Calvin Stevens in 1962 and since then it found a firm place in clinical anaesthesia. It has unique properties as compared with other anaesthetics as it can be given intravenously, intramuscularly, orally and via other routes. Moreover, haemodynamic stability is maintained when ketamine being used and is a preferred anaesthetic while managing a shocked patient. In this article Dr Sher Mohammad and others look at the effects experienced of the dissociative anaesthetic ketamine.
The pharmacology is briefly outlined in table-1
Why Ketamine is a popular recreational drug
Unfortunately, since the 1980s, this drug has been abused as a recreational drug in night clubs and house parties. Its popularity has increased tremendously because it has been erroneously believed to be safer than other recreational drugs. It is available in white powder, tablet or capsule form. When inhaled through the nostril, its effects appear after 10 minutes. The psychedelic experience (‘trip’) includes the sensations of light throughout the body, sensation of being weightless and floating or hovering, colourful visions and out of body experience. The bulk of a ‘trip’ lasts for about an hour and the effects diminish gradually over another hour. This is the experience that the addicts crave for.
What is K-Land and K-Hole
K-Land refers to the effects experienced at low doses of ketamine. The abuser may feel euphoric and experience mild dissociation, where s/he feels slightly detached from reality and the surroundings, but still have some bodily control and environmental awareness. Mellow and colourful experiences(K-land), sink into a blissful infantile inertia (Baby food) and believe that s/he has met the God, are the descriptions.
K-Hole means feeling of falling into a hole or stuck in a hole and it refers to an intense dissociative state caused by a high dose of ketamine. In this state, people may feel completely disconnected from their body or surroundings. Research has shown that this phenomenon occurs due to ketamine’s strong antagonistic effect on NMDA receptors in the brain. Some report out-of-body experiences, while others describe it as entering a void [1].
When someone has “fallen into K-hole”, they are temporarily unable to interact with others or the world around. It is a state between intoxication and coma.
The K-Hole is typically considered undesirable and frequently occurs due to accidental overdose, but occasionally the abusers will consider the experience of K-holing spiritually or recreationally valuable. The high dosages of ketamine necessary to induce a K-hole are unsafe and carry significant physical and psychological risks associated with both acute toxicity and chronic exposure.[2]
Why Does the K-Hole Happen?
Ketamine is a dissociative anaesthetic that fundamentally alters neural connectivity patterns [3]. Studies indicate that ketamine disrupts the default mode network, leading to altered states of consciousness [4]. The acute effects of ketamine vary by dose, setting, and individual biology. In recreational settings, people often take too much or mix substances—raising the risk of slipping into a K-hole.
Ketamine is also used in the Management of Treatment-resistant depression
Ketamine and esketamine represent a significant advancement in the management of treatment-resistant depression and acute suicidality, offering rapid antidepressant effects through glutamatergic modulation and enhancement of synaptic plasticity, rather than traditional monoaminergic pathways [5][6]. However, their use is associated with important risks, including transient dissociation, psychotomimetic symptoms, and potential for abuse, which necessitate careful patient selection and monitoring [7][8][9].
Recreational usage
Ketamine recreational users have found great appeal in its antidepressant, dissociative
