was my weed laced with acid or some type of drug?

What drug was my weed laced with?

This happened awhile ago, but I made a very poor choice of smoking a random blunt at a concert. The blunt was wrapped in brown paper which didn't seem different to me, but the hits I took which weren't as extreme as ones I've taken in the past, were so powerful they made me tear and cough uncontrollably.

Within about 10 minutes which I assumed because my sense of time was distorted, I started to get a bit worried because the person who gave me the blunt was gone. I started hallucinating (i.e. the artists at the concerts were floating out of the screens, they're mouths were opening wide, and my vision looked like static). I started to worry even more so I asked people around if I was okay and they noticed I wasn't feeling too well.

I've had bad trips before so I'm familiar with the feeling, but this was unlike anything I've ever felt throughout my 3 years of smoking on a pretty regular basis. The concert was at night in the fall and it got very very cold and I unfortunately only dressed in a t-shirt and shorts. My body started shaking uncontrollably and I still knew that I would be in trouble with security if I had a public breakdown so I kept to myself.

I was so cold to the point of where I felt freezer burnt and I knew I wasnt well enough to function in the slightest ways to get a bottle of water. So at this point, I guess about 2 hours into the concert I'm shaking like a maniac, parched from no water, and grinding my teeth and feel like they're going to fall out which I know is a meth symptom.

I tried texting my friends and it took forever for me to send one text with a crap load of typos and I thought I was going to die. The thought of dying didn't scare me but since I was elevated from the stage I thought I was going to fall down a tier of stairs and die in some horrific way. I felt like a superhero, spread out my arms, and tried my best to enjoy the rest of the concert, despite the fact I was still convinced that would be the night of my death. My life was flashing before my eyes about whether my mom would see me the next morning or how I would get out of the venue by myself.

That night I got home and couldn't stop talking and about an hour later I fell asleep. The next morning I woke up and I couldn't remember a single thing. I felt hungover and worried because I knew something terrifying had happened the night before but I was so thankful to be safe at home. I was still worried about the memory loss and I felt like my brain had been permanently damaged to some extent. Some of my friends suggested that the weed was either laced with coke, ex, or meth.
