what would give a false positive for thc also
5 Oct 2010
I believe I posted this article for you before. So many testing facilities have less quality control and over sight than many restaurants. There may be other medications (besides the ones listed below) that may cause a false positive for cocaine. Take care, concrispy!
Laboratory slip-ups are to blame for many of the mistaken test results. But even perfect labs running perfect tests will also find many false positives.
False positives are caused by:
*Nasal decongestants such as Dristan, Neosynephren, Vicks Nasal Spray, and Sudafed, which cause false positives for amphetamines.
*Poppy seeds like those on a dinner roll, which cause false positives for opiates. Even the highest-quality test currently available, the GCMS test, still confuses poppy seeds with heroin.
*Pain relievers such as Advil, Nuprin, Midol, Trendar, or any medicine containing Ibuprofin cause false positives for marijuana.
*Antibiotics such as amoxicillin or ampicillin cause false positives for cocaine.
The above list is only a beginning. Most substances which people have in their blood have never been tested to see if they cause false positives. Indeed, even some natural body enzymes cause false positives. According to research validated by the Congressional Office of Technology Assessment, melanin, the natural pigment which makes skin dark, can cause false positives for marijuana
