The increase in recreational use prompted ketamine to be placed in Schedule III of the United States Controlled Substance Act in August 1999. Recreational use
At sub-anesthetic doses ketamine produces a dissociative state, characterised by a sense of detachment from ones physical body and the external world that is known as depersonalization and derealization. At sufficiently high doses, users may experience what is called the "K-hole", a state of dissociation with visual and auditory hallucination. John C. Lilly, Marcia Moore, D. M. Turner, and David Woodard (amongst others) have written extensively about their own entheogenic and psychonautic experiences with ketamine. Turner died prematurely due to drowning during presumed unsupervised ketamine use. In 2006 the Russian edition of Adam Parfreys Apocalypse Culture II was banned and destroyed by authorities owing to its inclusion of an essay by Woodard about the entheogenic use of, and psychonautic experiences with, ketamine. : 288–295 
Recreational ketamine use has been implicated in deaths globally, with more than 90 deaths in England and Wales in the years of 2005–2013. They include accidental poisonings, drownings, traffic accidents, and suicides. The majority of deaths were among young people. Because of its ability to cause confusion and amnesia, ketamine has been used for date rape. Research

In biology, meconium describes the metabolic waste product from the pupal stage of an insect that is expelled through the anal opening of the adult upon eclosion from the pupa. Other insects, such as beetles and some Hymenoptera (Aculeata) expel the meconium at the end of the larval stage, before becoming a pupa. Gallery
