Can Nyquil use the day before a US cause someone to pop positive for methanmphetamine? <VANITY>

Washington Stat Ping!

I attended a Town Hall meeting yesterday with one of our local Washington State Legislators who lead off the 3 hour discussion with a long rambling story of a constiuent of his that was doing a followup UA test after a DUI conviction, and he said that since the night before the pee test she had used Nyquil and Theraflu, which he said both contain pseudoephedrine, the next day she popped positve via Urinalysis for methamphetamine.

That sounds questionable to me, so I tried running it through Snopes with no luck, but I have never heard anyone say that pseudoephedrine itself could test positve for methamphetamine. One may be the precursor of the other, but they are chemically quite different, and I think the test for one may not even work for the other.

Does a Urinalysis test look for pseudoephedrine as the trigger for the test, or is it some other compound in the meth that does it?

Can someone help me out here, and steer me to the facts that either prove this statement out, or refute it completely. It's important to nail this one down because of the person who made this statemnt.

I think this would be more easily answered on DU.

It depends on the local custumes. And what kind of beeber-like device is involved here?

I don’t know about the testing, but anyone who took both of those drugs were definitely flying and should not have been behind the wheel. I don’t how long it stays in the system, but since our state lab is in question for reliability, anything is possible.

How was she still standing?

A drug screen might come up with a false positive, but the correct thing to do in that case is then to submit the sample for more expensive and precise testing by a lab. When they run the big chemical analyzers, which cost a few hundred dollars so they don’t use them for screening, the exact chemicals present are identified. At that second-level testing, they can tell Nyquil from meth.

That is true, it’s been a problem in pro sports testing regimens for over a decade. Especially problematic in cycling, due to meth being a good drug to enhance cyclists performance, and the fact those guys get lots of colds doing mountain training before mountain races.

Looking at there structures I can see how you can get a false positive. ANd if I remember right to synthesize meth most homebrewers use lots of sudafed.

It sounded like the woman took those meds at bedtime, and the following day went in for a urinalysis as required due to a previous DUI.

Or I could be completely wrong.

lol

Actually, an interesting question. I cannot take anything containing pseudo ephedrine. The last time I took two of those little red pills, the recommended adult dosage, I was up, WAAAAY UP, for two days! Couldn't’t stop talkin.”
