I once heard that ephedrine could make it look like you use methamphedimines. Is this true? are there any others that can give a false test reading?

Ephedrine is closely related to the amphetamines, and has similar effects.

Since most urine tests test for metabolites of drugs, rather than the drugs themselves, and since amphetamines and ephedrine have the same metabolites, ephedrine could cause a positive result for amphetamine.
Learning about the in’s and out’s of internet marketing can be difficult unless you have a great mentor and where can that mentorship be found? If you really want to succeed online you must get yourself a copy of Commission Blueprint 2.0 created by Steven Clayton and Tim Godfrey. The tools alone are worth the cost alone. Best wishes!

There are dozens of supplements, foods, drugs, and diseases that can cause false positives on drug tests. Too many to list.
