Although I rarely use ephedra products its dumb as shit to stick blame to it.
If they have a heart condition in the first place its entirely there fault for taking it, if hemophilias (sp?) (poor blood clotters) were to take asprin and bleed to death, would asprin be taken off the market? Plus it was made for healthy adults, not un-healthy obese people who dont exersice and expect the supplement to beat of there 8000cal carb/sugar diets.
