Can Amoxicillin Cause Positive Result In Drug Test?

ii feel awful. i know my best friend never used drugs. i gave her some of my amoxicillin. she was trying to fight off a cold. she also took different medications from friends and family for her back and knee problems. she felt she had too much to do and would not stop and see a doctor. she was given an urine test, and it came up positive. could that caused her to fail the test?
