Did I smoke PCP laced weed?

Okay so we bought weed from our brother and he told us it was medical. We smoked about 2 bowls and than we didn't feel it fer a lil all of a sudden we all start Shacking HARD and could not feel our body's. We thought we could jump off the balcony and survive it. We kept feeling our hearts getting hot and beating REALLY FAST we kept seeing things and couldn't walk. It felt like we were puppets being controlled my strings. we would shake so hard it looked like a Minor seizure. I'm thinking it was laced with PCP? What do you think? The other option i was thinking is it was sativa and indica mixed?
