Hmm, just my 2 cents : Ephedrine is a form of speed which is an A-Class drug. It is very addictive and is linked to heart problems, especially when used in combination with exercise. I know it is sold freely in health food shops. That doesn't mean it is safe ! Be carefull when you take it. My friend at home was addicted to speed, and she was skinny as hell, but she also had a year-long fight to come off the stuff and is now on anti-depressants
