A few months ago I had two friends over and my parents were out so we decided to smoke. One of them rolled a joint with about a dime (half of a gram) of weed that we got from a different but trusted source. I took six hits and remember saying that it tasted really bad, bitter. I've smoked a pretty decent amount in my life so this isnt new to me. Afterwords we go inside and sit down at my kitchen table. All of a sudden I completely zone out in a tunnel vision towards the digital clock on my stove. It was almost like looking at myself in the third person. I think wow, i've never felt this disconnected after smoking. Then I get up to grab some pizza and I get the sensation that i'm about to faint. I have fainted once before and the feeling is that of everything turning black and yellow and loss of balance. I then stumble into the other room with my heart beating out of my chest and a feeling of depressed and difficult breathing. After a glance in the mirror my face was pale white and my eyes were completely glazed. Then the thought entered my mind: this must be what it's like to overdose and die on a drug. I immediately stumble to a couch and sit down. Yellow spots then fly across the room. My two friends sit down also and told me that I lost all motion in my face. They would ask me something and it would take ten seconds to respond with a one or two word answer. I kept sitting on the couch and within a half hour the acute effects went away but I was far from sober. Within two hours I fell asleep. My friends the next day said that was the highest they have ever been and that they also smoked another joint. Both of them dont think that it was laced but I think it might be. After talking to this girl I know who has had experience with pretty much every drug, and I sent her a picture of the condition I was in at the time, she thinks that it was laced with the dissociatives pcp or ketamine. I'm still trying to figure this out after three months. Any idea?
