YES YES YES it will.
Ephedrine is an amphetamine. It and Meth only has one Element "OH"(chemical) different. < IE its a precoursor.
A simple blood test or other fluid than urine would be able to verify the difference 9 in a good lab) ... But a Pee test will get you for Amphetamine use every time... if its in the window of 3-5 days.
Sad to Say even psudoephedrine can cause false positives.....
