can detuss cause a false positive on a drug test for crystal meth?By Tracy from Pine Bluff, AR on December 23, 2005 Category: Detuss (Oral) My son has recently failed a home drug test that his dad gave him. It said he was positive for crystal meth. Two days ago he began taking amoxicillian and detuss for an ear infection and cough. Could any of these things have caused the test to show a false positive for crystal meth? |
