Ketamine is a ‘disassociative’ anaesthetic. This means it causes a sense of being separated from the world around you, as well as sedating you and dulling pain like a normal anaesthetic. Ketamine cannot kill you from overdose in the way other drugs like heroin can but it has been implicated in an increasing number of accidental deaths, such as drowning or falling from buildings, because users are simply not aware of what is going on around them.
The specific effects of driving on ketamine are:
Distorted perceptions and hallucinations
At higher doses – becoming completely unresponsive to the outside world
Drastically slowed reaction times
