Was my weed laced and is my brain fried?

see last year me and my homies was cooling at one my homies friends houses and we was riding this 6 foot bong and this one foot bong and well for the first 3 hours we only had a 16 gram bag of shake. and the owner of the house said we could smoke it cuz he tried to roll a blunt with it and it tasted nasty *** **** well when i took my first hit it tasted nasty as **** and i choked hella bad felt almost like i couldnt breath...(and dont say it was cronic becuase my cousin always gives me sum his medical marijauna so i prolly get better ween than you) well anyways it tasted like burn food mixed with cheecmicals and bad weed.. so i start seeing **** the guy and his girl friend was fighting in front of us but every time she yelled it was like when a drop of water hits a pond and all those waves shoot out except the waves was going twords me and the room was sorta spinning and noises was all slow sounding and i was sort of seeing colors. weel anyways my questions are first was it marijuana laced with pcp. now my second question is that well i smoked 5 grams of it by my self do you think my brain is fried or fu_cked up or i wont function proporly now?? thanks and if i get any comments saying dont smoke i will report you
