There are no specific memories of the first time I used ketamine, which was around age 17 or 18. The strongest recollection of ketamine use regarded an instance when I was concurrently smoking marijuana and inhaling nitrous oxide. I was in an easy chair and the popular high school band Sublime was playing on the CD player. I was with a friend. We were snorting lines of ketamine and then smoking marijuana from a pipe and blowing the marijuana smoke into a nitrous-filled balloon and inhaling and exhaling the nitrous-filled balloon until there was no more nitrous oxide in the balloon to achieve acute sensations of pleasure, [adjective describing state in which one is unable to comprehend anything], disorientation, etc. The first time I attempted this process my vision behaved as a compact disc sound when it skips - a single frame of vision replacing itself repeatedly for over 60 seconds, I think. Everything was vibrating. Obviously I couldn't move. My friend was later vomiting in the bathroom a lot and I remember being particularly fascinated by the sound of it; it was like he was screaming at the same time as vomiting, which I found funny, and he was making, to a certain degree, demon-like noises. My time 'with' ketamine lasted three months at the most, but despite my attempts I never achieved a 'k-hole.' At a party, once, I saw a girl sitting in bushes and asked her what she was doing and she said "I'm in a 'k-hole.'" While I have since stopped doing ketamine because of availability and lack of interest, I would do ketamine again because I would like to be in a 'k-hole.
