Not positive, but ephedra prolly clears very quickly and since alot of cold medicines contain it, they are testing for concentrations that would lead to performance benefits. So, if I took ephedra today at noon, I would think the levels they are looking for would be clean 6-12 hours later.
The half-life is 3-7 hours, so if you can find out what blood level they are looking for, you could easily figure it out.
