Drugs Marijuana COULD IT HAVE BEEN LACED?

This week i recieved a gram of "purple haze" ultimately its was a really hard consistency and to me it seemed like mexican box weed possibly laced with something(wasn't even purple). well nevertheless i smoked this stuff and on several occasions it made me trip pretty hard. i had this rush of pain/tingly feeling in my neck along with the most incredible body high. also it made me pretty delusional/ this feeling of being away from my body. I have used hallucinogens before and am an advent smoker so i figured something might be up with this weed. WHAT COULD IT HAVE BEEN LACED WITH
