I think i smoked laced weed last night

Man Last Night I think I was smoking laced weed. I haven't seen my friend in two years and the last time i remember smoking with him was when i was in college a year ago and When i smoked his stuff i didn't feel like i usually do when i smoke weed. Just yesterday night we caught up and chilled at his place and we smoked and I felt the same effects but more intense like the last time i smoked with him. My breath was getting very shallow, felt pain in my chest, specifically the left part of my chest but up towards the collar bone. I Felt like my throat was closing, could not really breathe out of my nose, my heart was racing faster then when I smoke my weed but had worse cotton mouth then when I usually smoke weed. After I drank something, my mouth would go right back to being extremely dry in seconds! Felt extremely over the top anxiety. I also felt very tired and dizzy. I don't know if it was laced but when I smoke my own stuff I don't feel that type of way when I smoke my stuff. Does anybody know if I might have had laced weed or not?????? This morning I feel 40% better but i noticed my pillow and part of my sheets were wet with perspiration. Might had the cold sweats or something but feel a lot better this morning than last night. I've smoke weed every day now and never experienced what i experienced last night, felt like i was going to die or something with the effects i listed above when i smoked my so called "friend" but when i smoke my own stuff, I don't get those side effects or the cotton mouth and the increase heart rate like when I smoked my friends crap last night!!!
