I have a question for all you weed smokers?

So me and 5 other people were smoking a blunt. I took two hits off that and then 3 hits off a bong. As soon as I smoked I started feeling really dizzy my ears started ringing I couldn't keep my balance. I felt high and extremely drunk at the same time. I was really disoriented. I threw up a lot. I've smoker weed a million times half the time I stay high all day and I've never felt like this. I hadn't been drinking and I wasn't high already before I smoked that. No one else got sick either. Does anyone know what happened.
