I've been reading through these forums for a while, made an account today so I could talk about this scary experience we had a few days ago on what was sold as acid. My friends have bought tabs from this girl before several times, all with similar experiences, with 1 tab being more intense than any trips with other people's stuff, and 2 tabs being the limit for everyone. These are not inexperienced people, but the dosage is a lot stronger than anything before this. So my friend who hasn't tripped in a month or two took just 2 tabs and everything was fine, started feeling a little euphoric and antsy an hour or two in but didn't peak until around 2.5-3 hrs in. At this point my friend is having extreme visuals and is completely unaware of where they are. Speaking to this person is very difficult to do because they will not focus. At one point I continuously asked them to stand up and they just stared at me looking wide-eyed and scared. After this point, they are barely able to walk without stumbling and falling over. They pee their pants at this point. This is where they start looping. What begins as the repetition of a mumbled few phrases becomes the shrieking of about 10-15 different words/phrases that lasts for hours and hours without stop. This person is does NOT stop talking and they are unable to say anything but this handful of phrases in different orders. Strangely, at times they will respond to the situation appropriately via their tone. For example, if we are trying to get their attention or get them to focus on us, for a moment they will change their tone to an understanding one, still repeating the same words. My friend who has never been violent in any way before, tried to fight several of our friends. The screaming lasted for around 3-4 hours and at the end he had fallen down the stairs several times and was bleeding from his head so we took him to the emergency room partially because of that and partially because there was absolutely no way to keep him from breaking everything and hurting himself more except for pinning him down which only lasted a short while anyway. After he had come down many hours later, he had absolutely no recollection of anything except a few blurry things that happened right before he peaked. I'm sorry this post is so long, but this has never happened to us before, and I am curious if we are normally taking LSD and got a batch of something else this time or if we are normally receiving some other kind of chemical and this time was the real LSD. Apart from that, I am wondering if anyone else has witnessed or heard of events like this. I read about one on a forum a while ago, but apart from that, I don't know what could have been different from the 1.5 tabs everyone else in the group took and the 2 tabs he took. He was not in a bad setting or mood and no one else who has taken tabs from this batch has experienced anything similar. I guess I'm just fishing for any kind of relatable stories or answers that may give me more insight to this or give me a head's up to any kind of after effects he may experience. Thank you
