I also believe the city one lives in, the history, if any, of corruption in the police department, and the one doing the testing has much to do with the result. Three of my first cousins are Chicago cops, along with two boyhood friends and they agree, so I'm certainly not biased against cops.

I am trying to find out if lidocaine that was gargeled and spit out will cause a positive drug test? Any input would help. Thanks!

Here is an excerpt I copied from an interesting article. I hope this helps.
False positives
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 ibuprofen 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.

Do you drink any kind of tea? I had a false positive b/c of either green or white tea in excess.
