You can take this as a warning or maybe even as a bit of reassurance if you are currently experiencing a "bad trip" on marijuana. This has happened to me twice and both somewhat recent. I am not an avid smoker. I started smoking about a year ago but back then it was only maybe every other month. Within the past 2 months it has become about once a week but my tolerance is INCREDIBLY LOW. I can get high off one slightly large toke of some mids. Extremely high. Stoned out of my mind: a dream state, video game, depersonalization, cant think about anything. Anyways, friday night i got ripped as f**k. I took 2 smallish hits out of the bong and felt good but started to feel the depersonalization. It would have been a good time to stop but i had been talking to my friend earlier about toking so huge id pass out and wanted to do it. HUGE MISTAKE. I reclined my seat (cruising in his car) and had my friend in the back seat light and pull. He knew the goal so with my permision he lit the entire bowl and i milked that thing for a solid 8 or 9 seconds HARD. Almost immediately after clearing i started to cough but i felt like i wasnt clearing my lungs and couldnt breathe out all the way because i couldnt stop the half coughs. This went on for about 30 seconds and i felt like i was going to puke and pass out. I was immediately high as HELL. For the rest of the night my heart was racing and i couldnt walk for 2 hours after the session. I couldnt think straight and i struggled to talk at all to my friends. I knew id sallowed a decent amount of smoke as i couldnt stop the urge to burp and puke. At one point i had a massive burp and could taste the disgusting smell of old nasty smoke and puke. Also whenever i get this high i feel like every breathe i take is pure smoke or that my throat has fire in it. Every smell is a million times stronger, so strong that i can taste it to a disgusting degree. When i tried to talk i couldnt think of words and my voice was practically silent. I spent the night laying back in the parking lot of taco bell basically seizing up. Every muscle fiber and ligament thingy in my body was twitching like crazy and kept cramping all over. I had to put pressure on my neck to stop all the little fibers from flexing. Half way through the night i achieved my goal and passed out for about 8 seconds. I can barely remember passing out but i had a dream while i was under. I felt a tad bit better for maybe 2 minutes but quickly went back into a state of leaning my head back staring out the window and slapping my hands on my chest and stomach. I was so out of it that i was thinking "i look like a retard but thats good cus people will think im retarded not high" lol! I know that weed has never directly killed anyone and it is not at all the drug people are taught to think it is, and so i never thought i would die or become injured in some way yet i couldnt stop panicing. The worst part was ruining the high for my friends honestly... Or atleast looking back it was. At the end of the night, still wobbling around and struggling to speak coherently, i had to go home and face my mother. We didnt talk much but im sure she realized something is up. I felt kinda out of it like i still had a buzz until about 2PM the next day. Id like to think none of it wouldve happened if i hadnt taken that last hit, but it very well could have anyways. For that reason, i am going to attempt to quit smoking marinuana. This probably will not happen but at the least i will only smoke out with friends and very little at a time. Most people do not experience this at all with marinuana. I believe i am just one of those people who do not mesh well with weed which sucks because i enjoy when i have a controlled high. Anyways thats my story! Oh and we were originally planning on blowing tree in a park but right before we got out of the cars with all or stuff a sheriff pulled up and we flipped out. He told us he had a freakin dog with him! We called his bluff though and he just ran our ids and let us go but we had paniced and tossed the weed in the woods. Remarkably we found the little baggie in the leaves when we walked back later. We hit the bowl hard for that sheriff sorry for any spelling mistakes and the length lol peace!
