Re: JonD (# 349)
Depends how "briefly" you mean. It can soak in through your skin or even vapors in the air can get into your system. That's why the DEA will dress up like astronauts when busting a lab. Methamphetamine is a crystal substance that when made and even smoked is turned into a vapor and that vapor can get into your system. Now if you were just touching a crystal to look at it then depending on conditions it would enter your system. We're you sweating? How long were you touching it?

I would normally agree, as Everytime I failed a drug test I used. I have been clean from illegal street drugs for over 3 years! I am however prescribed Adderall and I take zantac and much is the case with many others here, I tested positive for methamphetamine! I'm from Jersey and that is not a drug you can find unless you are a biker! My employer and personal physician agree with me and as long as I produce the necessary documents for the amphetamine, I will be fine.

That's not the card with me..I have to do a random urine drug test once a month and I recently ( past 3 months) been put on thyroid medicine..the past 3 random urine tests have showed (false) positive for methamphetamine! So taking Benadryl, Tylenol PM, Advil PM, Ranitidine and Trazadone long with Thyroid meds has caused the false positive. Before taking thyroid medicine I have NEVER had one bad test result in the 4 years of doing the required random testing.
Re: steven dixon (# 6)
Yes, alot of the drugs you mentioned cause false positives. However if the lab knew of these meds they would of done more in-depth testing.
Re: steven dixon (# 6)
I am not familiar with a lot of the medications you listed. However I do take gabapentin and I have taken amitriptyline and the 1800 mg of Gabapentin is way too much That could absolutely be causing some of those symptoms. Also I think the amitriptyline could
I have taken a 15 panel home drug screen and it's giving false positive I take Vistaril Geodon Acyclovir loratadine montelukast Protonix voriconazole and have taken Sudafed what should these come up as on a home drug screen
I just started taking Jet Alert because I work 6p-6a and was wondering if it would show a false positive on a drug test?

Re: Robin (# 13)
I recently showed up positive for methamphetamine and only take Xanax & Lodipine for sleep and I don't do drugs. Is there a lawyer or something I can do to fix this? Please respond if you can help me. Thank you.
Re: vlady (# 52)
Yes it can make you test positive however if you let testing facility know you took it then may be good but I think it only test positive for alcohol
Re: jlchate (# 28)
I take the same acid reducer and have never tested positive in the National Guard or at work for fed ex. I do take lexapro and have tested positive for it, but it's prescribed.
Re: Doctor John (# 123)
I just failed a UDS for methamphetamine & amphetamine from using benzedrex, when I didn't use anything else at all. Just the benzedrex.
Re: Lynn (# 4)
Its probably the zantac from what I've read. I am not sure why but evidently something in it reduces to a methamphetamines base.
Re: Doctor John (# 172)
I had gastric bypass surgery approx 14 years ago and bc of complications with that I take large amounts of Zantac, (sometimes upwards of 1200mg daily). The first time I had a false positive was about ten yrs ago. The MRO, I think that's what they call them, told me that my gcms test came back 79% positive for d isomer methamphetamine. I've never even seen methamphetamine in real life, only on TV. I did pay for a hair follicle test to prove that I was innocent, but did still lose my job. There now is research saying gcms testing is no longer the gold standard bc of the difficulty of actually understanding of the results in reference to methamphetamine. Obviously above my head, but it's devastating that this isn't well known and or talked about in medical journals. You can actually call Zantac and they will admit it to u, but will not release paperwork verifying it, bc the "information is for medical professionals, not the general public" so anyone who needs proof, call them and record the call.
Re: Jennifer (# 321)
Did the lab test come back negative?! This just happened to me- I took a Zantac last night and had a UA this morning-tested positive. They are sending it to the lab-will I be okay?! I’m FREAKING out
Re: steven dixon (# 6)
Gabapentin and cybalta have very moderate drug interaction they say lower dosage on gabapentin
I had a mouth swab test and the lab where they sent it left me a message to call them back asp, but can't till Monday. First of all that can't be good and I take pain medication and sleeping medication. Could anything like that show as methamphetamine?
