I know this, from personal reasons. I have a heart condition, and passed out at work. I had been having terrible headaches so I was taking tylenol as often as was allowed.

During my lovely stay in the hospital it came out they thought I had taken amphetimines which caused my heart condition. They swore it, and even wanted to transport me to a drug rehab after leaving the hospital.

Come to find out, my sister did research on the topic, and showed the hospital all her findings.

Not saying this is true in Brit's case, but having been there done that, can go by my experiences.

Many things, cause false positives.

A lot of people I know always write down on their forms when having drug tests that they've taken some kind of cold&flu tablet with pseudoephadrine in it cause that will explain a positive reading. Unlike you, they are actually trying to create a 'false positive'. But it also depends on how much amphetamines are in your system - a 3-day speed bender will kind of dash any hope of being able to use the old "cold & flu tablet" trick. Also most tests now test seperately for amphetamines and methamphetamines... the "cold & flu tablet" trick doesn't work for meth.
