Subj: How long does ectasy show up?
Date: 3/29/2011
How long does ectasy show up in a urine test? Im having a medical test tomorrow. I am a flight attendant and fear I will lose my job. I do not take when working but I did take approximately 10days before the test. I would appreciate any infor you have. Thank you
CHoi

AskDocWeb: In a worst case scenario ectasy may show up on a urine test up to a week after taking it. Typically it takes about four days to clear your system but that depends on BMI, age, how much you took, and how well hydrated you are, and the potency of the drug. We have heard that many of the street drugs are not pure MDMA and frequently contain amphetamines, DXM, caffeine, ephedra, and MDE, all of which together can show up as both amphetamines and methamphetamines.


Subj: Trying to figure this out
Date: 3/30/2011
I have a friend that has been on methadone for years. Her drs office has decided that they can't keep her there anymore and are tappering her down pretty fast. She has a lot of medical problems...she is also on oxycodone. And she has some wounds that she gets wrapped. They use (don't know the actual name yet) this cream that is called benozo? something. She has come up positive for benzos twice and then negative twice now today she came up positive again. Believe me she wouldn't risk them cutting her off completely and she's never been into benzos. On Monday they used a lot of that cream due to the amount of pain for them wrapping her leg. Could this cause a positive for benzo? She's asked to see the levels and all that they say they don't show a level.

Also this is personal and a little weird to be asking BUT if her husband takes it (diazapam 10mg) could she get it through him from sexual intercourse? Or orally? We are seriously trying to figure this out. Any help would be appreciated. Thanks
michelle

AskDocWeb: You may not be able to figure this out until you know all of the medications she in on, including name of that cream. Some urine drug tests show only the presence or absence of drugs in a yes or no fashion, without providing a measurement of levels. It is highly unlikely that she could be getting it from sexual intercourse with her husband, including oral.


Subj: Betzmethasone?
Date: 4/1/2011
Can you test postive for having a shot of betzmethasone?
Martha

AskDocWeb: We found no reference to betzmethasone related to false positives. The closest was Betamethasone but that was in reference to false positives on glucose screening tests, not for drugs of abuse.


Subj: Positive for morphine
Date: 4/2/2011
I need help and quick as my friend is heading to court soon for a revocation of probation hearing next week. He has had several dirty urines show up positive for morphine yet he steadfastly denies using (even his PO and drug counselors believe him - but the law is what it is). We are around him 24/7 and he has been fine until the last few months. He has NOT taken any opiate based medicines or eaten poppy seeds of any kind. He is on methadone (100mg) daily and it's been a lifesaver. He is literally days away from being released and now we're back to square one. It's a nightmare. My friend has shown early signs of diabetes (though as of yet hasn't gotten it checked out), he's also had trouble with his prostrate and kidneys from time to time (pain in lower back, chills, etc). Could anything inside of his own body be throwing off these tests? If so, what? And will any of it matter to the court?
Greg

AskDocWeb: There are several sources that say diabetes can show up as false positives for a number of things; amphetamines, cocaine, THC, ecstasy, meth and opiates (References 3, 15, 16, 20, and 21). However, whether or not that makes any difference to the court, you would have to Adask a lawyer.


Subj: THC
Date: 4/3/2011
I was smoking marijuana up till just over 6 weeks ago. After 2 weeks of intense cleansing with a variety of herbs, intense exercise and tons of water I purchase some 5 panel test kits, I tested clean, I did not smoke and about a week later I tested again and now I was positive for THC. I've continued cleansing and 4 days ago purchased a 7 day cleansing kit. Half way through the second day I tested, the test line was not very bright but according to instructions this is a clean result. I tested the next day and the stipe got brighter and I was very encouraged. I just tested today (3rd consecutive day) and now the stipe has totally disappeared. I have totally abstained for 6 weeks and it is a urine test, all my research says THC in the urine beyond 4 weeks is very rare and with all that I've done including a continual physical fitness program. Any ideas I'm so depressed I need this test to go to work and have put off my potential employer for as long as I can.
Martin

AskDocWeb: Although it may be rare for THC to show up after 4 weeks, it does happen. One possibility is that your continual physical fitness program might be releasing the THC metabolites from your fat cells.


Subj: Drug test came up positive for THC
Date: 4/3/2011
My 15-year-old son was given Rondec DM (with codeine), Promethazine, Lomotil, and Amoxicillin for various illnesses over the space of a month. His drug test came up positive for THC twice during this period. They sent the tests to California, where the positive was confirmed (although I don't know whether they used GC/MS or not). He swears he did not smoke pot, and he's never tested positive before. The only response I can get from the doctor's office is that THEIR tests don't show positive for any of those medications. Could any or a combination of the above meds have resulted in a false positive for THC?
North

AskDocWeb: There are three sources that say Promethazine may test false positive for THC (Reference 3, 16, and 18).


Subj: I am confused
Date: 4/4/2011
I have Lupus and was sent to a pain clinic. I tested positive for cocaine? I am confused. Have not used cocaine. I am 58 years old. The sample was sent away to a lab, will they be able to tell me where the false test originated??
Jane

AskDocWeb: Probably not, more likely they will just confirm or deny the presents of cocaine.


Subj: Horrified to test positive for THC
Date: 4/4/2011
I had sx 3 weeks ago for hyperparathyroid disease(elevated serum calcium) and am currently taking ES tylenol, ibuprofen, trialozam and adderall. Recently did home drug test(left over from kids)and was horrified to test positive for THC. The only time I have smoked in years was 5 mos ago at a reunion. Rumor has it new mngmt is drug testing this week. Coc/mamp/and opi. are neg. Could THC stay in my system that long or could this be false pos. or kidney disease?
KK

AskDocWeb: Typically THC stays in the body for about (CENCORED) days. However, the more marijuana smoked and the heavier the body, the longer THC stays in the system. It is also possible that you just had a false positive. The home drug test kits are NOT 100% accurate.


Subj: 2nd hand smoke
Date: 4/4/2011
I was at a poker game where people were smoking pot out of a pipe made up of common nuts. They were smoking weed from British Columbia and I think the other was called skunk weed. I read online that 2nd inhaled smoke will not show up on a urine test, so I wasn't too worried. I handled the pipe when it was passed around the table, but I'm not a smoker cause I go through random drug tests at home. We played from 9pm-5am. I went home and at 7am, the urine lady came for my sample. Now would the smell of my clothes, or from touching the pipe, would that make me fail the test. Plus, I've been reading more and more how positives are showing up from inhaling 2nd hand smoke and all the test case studies I read say nothing about pipe use in there studies. There was 6 of us playing and the room was not a big one, just enough for a poker table, tv and bar fridge. My nerves are shot. Should I be worried?
W.

AskDocWeb: We can't see whether it would make any difference if the smoke came from a cigarette or a pipe, it's still second hand smoke. After spending 10 hours in a small room with pot smokers, you may have something to worry about.


Subj: BIAXIN
Date: 4/5/2011
Hi I would like to know what/if the antibotic prescription BIAXIN can show up positive for? Thanks
Tina

AskDocWeb: Biazin has not shown up in the research about false positives.


Subj: Positive for amphetamines
Date: 4/5/2011
i got a slaiva drug test done today it came back possative for amphetamines but i have not consumed any drugs for over 2 years now why did this happen? i am a smoker and have taken pro pluss to keep me awake for work could this effect the result???
N/A

AskDocWeb: The research into energy drinks is still in progress but so far Pro Pluss has not shown up. The only ingredient is energy drinks that has shown up is 2-Amino 4-Methyl Hexane, also known as Methylhexanamine. Its chemical structure is very close to that of amphetamines.


Subj: Failed a drugs test
Date: 4/5/2011
i have just failed a drugs test with my new employer, gutted as i had laid off the pot for around a month, now i find out its my Aptripla that i have been taking for a year..... after telling employers that i dont take any meds!
Phil


Subj: Energy drink?
Date: 4/5/2011
I went to the doctor yesterday and tested positive for thc. I drink starbucks doubleshot energy almost everyday and I do not smoke marijuana at all. This is so scary. Please let me know what I can do to clear this up with my doctor.
Christi

AskDocWeb: You might tell your doctor that you believe the test result was a false positive and that you want a confirmation test to prove that. If you don't contest the results then they become a part of your medical records, which could cause problems in the future.


Subj: Positive for benzos and opiates
Date: 4/5/2011
I am a methadone patient and have been for 11 years. I have been clean of everything else for 7 years, than today i came back positive for benzo's and opiates. I take seroquel, welbutrin and clonadine daily as well as estro gel and ibuprophen can any of those explain the posative. I feel like something i worked so hard for has been stolen. how can i explain these results? I am tested weekly and in 6 years not one posative but i have only been taking those meds for 2 weeks. help
Kerri

AskDocWeb: None of the drugs you list have been reported to show up as benzos or opiates, however, urine tests are not perfect and the result could still be a false positive. The only way to find out is to get a confirmation test. Typically a confirmation test done using Gas Chromatography/Mass Spectrometry (GC/MS). This is done by vaporizing a portion of the sample into a gas and then analyzing the way the components of that gas array themselves in the tube. The spectrum of the substances present are somewhat like fingerprints for each substance. Each substance has a unique spectrum. The results of the GC/MS test specifically list exactly what is found in the sample.
