Was my bud laced??

A few months back i bought some bud off someone whom I didn't know, big mistake i know, i had about 4 cones and as i went to stand up I immediately felt like i was going to faint, my mate laid me down in a corner of a garage and i was there for about 8 hours, that whole time i was shaking nonstop, couldn't talk, move and had a fast heart beat, i felt like i was going to pass out every second of that 8 hours
