It all depends on the persons heart rate, body mass, and blood pressure though. I know someone who died of a cardiac arrest from taking Stacker pills before they took the Ephedra out of them. He collapsed on the baseball field and died right there and he only took 3 of them.

We used to take these Ephedra pills back in college. They were called Yellow Jackets, and we'd use them for when were draggin' ass and needed energy to drink all night. I used to take them before class too, and one day I started to have an "adverse reaction" while sitting in class. I remember being really hot, and uncontrollably jittery, then my peripheral vision dropped away and I thought I was gonna faint. My heart was beating like a jackhammer. That was the last time I ever took those things, then they were made illegal a few years later.
