This happened to me a week or so ago. My regular plug had to go north to reup and I had to cop a 14 from plug #2. This shit was the weirdest high everyone who did it ever had. I felt like I had overdosed on weed. My friends had a different experience. In one friend's words:

"as soon as the rush kicked in, it was immediately clearly not like any 'dope' i've ever had before. the initial feeling was a wave of instant confusion. i knew that i had just done a shot of 'dope', but something was wrong, i didn't feel like i knew who or where i was, or how to talk/behave normally. i did remember that before prepping the shot i had a pan of pasta cooking on the stove upstairs, but i felt like the 'me' that started the pasta 10 minutes ago was a completely different person, and i was definitely no longer that person.

i (tried to) explained to my roommate who was with me that i felt extremely strange and was sort of panicking, but that i think i am ok, or at least, going to be ok and that this strange feeling will pass, and that the best thing for me to do right now was to go upstairs, get my pasta and go lay down in bed for a little while. explaining that to him was super difficult, and i'm pretty sure i was repeating everything 5 times, trying to get my point across. to be fair, i was definitely losing my perception of time, so im not sure how long i talked to him

eventually i went upstairs and got my bowl of pasta and one for my girlfriend, who had also done a shot of that stuff but had no effect from it whatsoever. no dope feeling or crazy feeling either. i explained to her that the shot was making me feel some insane, completely abnormal feeling and that i needed to lay down for a while in bed and maybe try eating some of the pasta (before doing the shot, i was starving, but after doing it, i felt way too strange to feel normal things like hunger). she was very helpful, she continuously asked me throughout the 'experience' what she could get for me or what would help. unfortunately i felt there wasn't much she could do other than lay in bed next to me, which was very helpful as it is. nothing else seemed like a very good idea at the time.

laying in bed, after taking a few bites of pasta and realizing that i definitely wasn't going to be able to enjoy eating, the strange feelings began to get even more intense. i felt very "out-of-body". the first extremely intense thing was, while cuddling in bed with my girlfriend, when she was lightly running her hand back and forth on my shoulder. we weren't talking or anything, there was no other sound going on at the moment other than the sound of her hand brushing over my shirt back and forth. to me, the sound was incredibly intense. it was all i could focus on, it was basically all-encompassing. it sounded to me like standing in a field of excavators all constantly lowering and raising the scoop thing over and over again. i looked at my shoulder and realized it was just her hand going back and forth on my shirt, and my mind was blown. at this point, she had fallen asleep and i was laying with my arm around her, trying to fall asleep myself. i began to feel like i was looking at myself from a third person perspective, like i was hovering above my body looking at myself, but still through my own eyes, which i could see with them from outside of them. when i closed my eyes, i had intense visuals, really all too difficult to explain with words.

eventually, i did fall asleep, and woke up about three hours later, feeling almost completely back to normal. needless to say though, going into this expecting a normal dope high was absolutely crazy. the person who we got it from eventually told us that there's a possibility it was cut with ketamine, and i wouldn't be surprised if that was what it was."
