Is Ephedrine good?

I was reading about diet pills. One I read about is ephedrine. I think their is a lot of controversy about whether it is good for you or not. I really think it couldn't hurt you if you don't over use it. I really haven't tried it. I just think everyone should do some investigation before they try anything new. That way you know whether it's right for you. Everyone has to make their own choices. Just try to do some research so you can make wise ones.
