The limit is 10 μg/ml urine. Ephedrine is produced from plants of the genus Ephedra. It causes the release of adrenalin and noradrenalin.
Ephedrine was available in pharmacies until 2001, but since it was misused in the majority of cases, public access has been stopped. The effect of ephedrine can be compared to adrenaline. However, the effect is weaker, but lasts longer.
