Experiences - Question about crazy effects

[Metomni]

So last night SWIM smoked a couple giant bong bowls of what he thought was simple weed. These are the effects, SWIM wants to know what could have been put in with the weed to cause this experience, or something similar. SWIM realizes it could have been some crazy-mind-blowing-hash or something, but he is skepticle.

After they smoked, SWIM was really high and just sat there watching the video games. Pretty quickly, SWIM started getting twitches and his legs went crazy. The twitches were pretty strong ones with his head and shoulders and they were not controllable at all. Then his legs would chatter up and down real fast and they did that for about an hour and 15 minutes.

He didn't have any visual hallucinations or anything, but his mind was going absolutely bonkers. He could speak, but it took some effort. His headspace was that of tripping, but it was not a trip he recognized at all. The closest thing he can think of was if he had snorted a mixture of 2C-I and cocaine.

Also, he got extremely horny. Like ridiculously, could have fucked for days sort of horny. Watching the video games was really fun and intense, but the pictures and colors didn't blur together or anything, it was really weird to watch, but not in the way mushrooms or LSD make things fun to watch. It was in a different way.

He woke up about 9 hours after smoking and he is still feeling pretty weird. He thought it was a weed hangover at first, but he almost feels like he is still getting slight active tracers.

He is trying to think of more things that happened to him or thoughts he had, but it is kind of hard.

He wants input, what could this have been?
