Kristen,
Some hair spray contains very high amounts of alcohol (at or above 90%) and should be noted as either ethanol, alcohol or SD40. These products pose a real and ever present danger in EtG testing and the danger lies in inhalation of the vapor. This phenomenon was first elucidated by Dr. Skipper in 2005. While it is largely a matter of timing, inhalation of vapors at the level of 62% abv can cause EtG to spike between 700-800 ng, well above even the 500 cutoff. Therefore, I would recommend switching to a hairspray that is not alcohol based.
Perfumes. This was tested by a pharmacy doctoral student,
Molly Starkey at Mercer Univ. These too can cause positive EtG at a lower level but above a 100 ng test cutoff. This result seems to be explained by inhalation rather than transdermal diffusion but the latter can't be ruled out. Once again, timing is a key factor of use. But the use of hairspray
and perfume would have an additive effect extending the window of detection.
Small amounts of alcohol in food, even trace amounts due to fermentation or the remaining alcohol not cooked off in food preparation will also create detectable levels of EtG. This was thoroughly tested by Musshoff and associates through the German Institute of Forensic Medicine.
Trace amounts of alcohol, as little as 1g consumed orally will spike above the level of detection on an EtG test with a cutoff of 100 ng, as demonstrated by Thierauf (see below).
Finally, none of the causes outlined above would result in detectable levels of alcohol (EtOH) in urine
but will create detectable levels of EtG/EtS.
