Is this a dissociative?

[dip]

I really don't know, can't tell and can't find out what SWIM smoked.
-SWIM was mildly drunk before he smoked it.
-he says the joint was a smooth, tobacco-flavored smoke, and the 1" joint/roach took a long time to smoke.
-lighting his finger until it turned red, he felt no pain.
-15 minuets after finishing, extreme non-stop laughter. Just could not stop. This lasted about 10 minuets.
-Cops show up, in which paranoia took over. SWIM had difficulty breathing with long and very deep breaths.
-Walking was tiring and robotic-like.
-feeling of dissociation (?) and extreme social isolation
-felt like he was trapped, and couldn't communicate or even speak to other people.
-when called by name, he put his hands up infront of his body ... trying to find his dissociated mind?
-about 3 hours after smoking, experienced diarrhea.
-next morning, woke to find his lip completely black with dried blood from being bitten (don't remember biting at all)
Comparing with other dissociate experiences, it might be 1 of those 3 substances, or what else could it be?
