Yeah, I'm pretty sure it depends on the type of weed you have. I don't know though, head highs and body highs are both awesome, I don't think either is better. Both at the same time is amazing though, only happened to me once. Smoked 4 g's of headies mixed with some good nug split with only one other person. Had a definite strong head high going and on and off body highs, it was pretty sick. My whole body like tingled and I felt like I was falling for just long enough to be cool without getting annoying, then it would kind of fade away and come back later.
