FYI: after taking parnate for months, i happened to have a blood test and it came back positive for amphetamine. i understood it wasn't suppose to do that, but i'm not sure how easy a false positive is to trigger. i know selegeline metabolizes to amph, and wellbutrin can also create a false positive, and though parnate is structurally similar to amph, i thought the conclusion was that it did not metabolize to amph. wether or not the amph test is selective enough to filter out true amphetamine structure from parnates structure is one question. or is this proof of the tendency of higher dose (100mg) to actually metabolize to amph?
hmmmm....?

> l8Your test result really is not an indication that amphetamine is a metabolite of parnate, since many things can cause a false positive for amphetamine.
Ephedrine, pseudoephedrine, propylephedrine, phenylephrine, or desoxyephedrine
(Nyquil, Contact, Sudafed, Allerest, Tavist-D, Dimetapp, etc)
Phenegan-D, Robitussin Cold and Flu, Vicks Nyquil
Over-the-counter diet aids with phenylpropanolamine (Dexatrim, Accutrim)
Over-the-counter nasal sprays (Vicks inhaler, Afrin)
Asthma medications (Marax, Bronkaid tablets, Primatine Tablets)
Prescription medications (Amfepramone, Cathne, Etafediabe, Morazone,phendimetrazine, phenmetrazine, benzphetamine, fenfluramine, dexfenfluramine,dexdenfluramine,Redux, mephentermine, Mesocarb, methoxyphenamine, phentermine,amineptine, Pholedrine, hydroymethamphetamine, Dexedrine, amifepramone, clobenzorex,fenproyorex, mefenorex, fenelylline, Didrex, dextroamphetamine, methphenidate, Ritalin,pemoline, Cylert, selegiline, Deprenyl, Eldepryl, Famprofazone) Kidney infection, kidney disease, Liver disease, diabetes

-hmmm, what a sloppy science...

You're kidding right? Vicks inhaler and kidney disease, and diabetes? Love Phillipa ps are you a scientist?

Vicks inhaler contains l-amphetamine.The first level drug test is a antibody test. Subject to false postive results. All positives
must be checked with the gas chromatograph-mass spectrometer (GCMS). GCMS is not subject to false positive results.It is standard practice to verify positives with GCMS, but I would check. If you are still positive
for amphetamine or its metabolites via GCMS I would suspect the parnate.

I really hate doing this, but I'm afraid I'm just going to tear my hair out if I don't correct this... it's actually l-methamphetamine.

It has very little abuse potential; hardly any CNS stimulation compared to d-methamphetamine. There's no efficient way to convert l-methamphetamine to its dextrorotatory isomer (the one found in street methamphetamine).
