While I read the article below, I found it to be void of the key facts regarding the "meth positives" from the Vicks inhaler. I have worked with a treatment agency and certified testing lab for some time now, and this article as well as Mr. Spellwins write up do not address the key difference between the molecules in the inhaler and actual street meth. Also, no mention was made of how these two substances can be scientifically identified in a given "postive" sample by thier uinique molecular structures.

While determining whether a person has actually been using the Vicks inhaler vs illicit meth is a bit challenging, by using a couple of specific GC/MS tests the answer starts to become clear.
The key difference is in the prevalence of the specific isomer found in the test sample. The meth D isomer is almost exclusively found in street meth, and this isomer is responsible for the infamous high that meth produces. On the other hand, the L isomer of meth is found in the Vicks inhaler.
The standard has been set up for this test and if a sample comes back positve (according to determined cut off levels) with 80% of the molecules being the L isomer, the vicks inhaler excuse is legit. If the sample is heavy on D isomer meth, the Vicks excuse is not valid. There is a bit more to it than this, and the reading below should shed some light on this question.

I would love to see the lab results and the specific tests that were done on each of the athletes that Mr. Spellwin mentions in his write up. As an FYI, Landis and Gatlin were caught due to the fact that "natural" (made by human body) Testosterone has more C13 than does Testosterone made from yams and soy. Even the good folks at Solvay Pharmaceuticals who make androgel will tell you this.
