Can you test positive for meth while taking warfarin?

Yes...you ABSOLUTELY CAN test positive for Amphetamines if you have been taking medication containing pseudephedrine.

METH breaks down in a persons system and shows up as Amphetamines in just a short period of time.

If you are taking a TIME RELEASE cold medicine that has Pseudophed in it...it continually releases it into your system...and...if you take it more often than prescribed...it can definitely read a false positive for Meth/Amphetamine useage.

This happened to my son who is on probation and even through all of the threats of starting all over with his drug treatments when he had been totally clean for a year..there was no amount of talking that was convincing his PO until he continued to deny it...at which time they ran his test through the 'second' level of testing. This second level is more defined and actually tells exactly what has been ingested.

His...came back that he indeed took PSEUDOPHED...during the time that he had a severe cold !

So IF you are telling the truth and you are CLEAN...stick to your guns ! Don't let anyone attempt to scare you into admitting guilt.
