I'll keep it simple. First time smoking weed, I hit the bong 6 or 7 times, on the last time I get a huge rip and swallow most of it, start choking and coughing. (Literally swallow, sometimes I could burp up stale smoke, even days after.) About 15 minutes later we get bored and decide to go for a walk. I can't feel anything at this point but as soon as we start walking, I notice the grass suddenly looks like it's waving, like its water. I can barely walk straight and feel like I'm going to fall over. My friends hold me up. I start panicking, my heart feels like it's racing. Visual distortions experienced include sharpened colors, strobe light vision. Almost an out of body experience effect, it seemed as if I was looking through my eyes from a stage, as if at the movies. (The high was similar to what I've experienced when on nitrous oxide; disconnection between mind and body.) There was also some weird time dilation effect, I would look to my right and time would seem to dilate and expand. Also temporal slowing, time seemed to pass very slowly, I could seemingly think multiple things in a split second. Severely impaired reaction time. I don't remember any dry mouth, or increased appetite, but my heart definitely seemed to be beating faster. I felt these effects on and off for about 8 days. I would wake up in the morning and feel fine, but a few hours later the high would suddenly blast me off my ass, visual effects and all. In the days following I felt constantly dizzy, almost flu like symptoms, inability to concentrate on one thing, I couldn't even hold a conversation for longer than a few seconds. There was also mild to extreme anxiety experienced through all of this. Was I just severely intoxicated, or is this a warning sign of something bigger, maybe psychosis?
