Does damiana show up on a lab drug test?


AskDocWeb: Damiana does not show up on a drug test for drugs of abuse.

I’m not admitting to taking something I haven’t taken!
Date: 4/30/2012
I recently started going to a doctor in January for Suboxons. I have had 13 surgeries & I am 30 years of age & I was tired of taking all the pain medication but hated withdrawing. The suboxons really help but I get drug tested each month & the 2nd month & this past month I tested positive for Methadone. It was very little of a trace but it was still there. The problem is I DO NOT & HAVE NOT taken methadone. I am a cash pay patient & wouldn’t even take a chance of taking anything to make me fail my drug test.

I explained to my Dr. that I have not taken any, but of course he says it’s in my system so it got there some how. He wants me to admit to it so he can help me BUT I’m not admitting to taking something in which I haven’t taken!! I take Goody Powders daily for my head aches, ibuprofen when needed, acid reducer over counter meds, & generic Tylenol PM every now & then when I can’t sleep. I’ve told him what I take & he says that none would cause methadone to show up!!

I can’t afford to fail another drug test especially when I haven’t taken anything!! Any ideas on what it could be & why its done it twice?? He uses in house drug tests & he says they are almost 100% accurate! So there is still like a .01% chance it shows up wrong.. I know its hard to believe but I don’t understand!! Please any comments or suggestions would be appreciated


AskDocWeb: The list of substances that might show up as methadone is short:

  • Antihistamines in general
  • Bentyl®
  • Elavil
  • Methadose
  • Nyquil
  • Phenergan®
  • Physetone
  • Vicks Formula 44M

If you are convinced that the test result was a false positive then getting a GC/MS confirmation test is probably the only way to convince your doctor.

Tested positive for THC
Date: 5/1/2012
What do I need to do if I have been tested positive for THC and I have and am taking 4 of the drugs that cause false positives? A couple for the past month in IV’s in the hospital.


AskDocWeb: If you believe your test result is a false positive then getting a confirmation test makes good sense. When we say “confirmation test” that doesn’t mean a retest or to test again with the same method. We are talking about sending your original sample to an outside independent laboratory for a GC/MS confirmation test. If your test result is a false positive, the confirmation test will come back negative and your medical record should be updated. Without that confirmation test your medical record is likely to label you as a drug abuser.

Positive drug test
Date: 5/2/2012
I just had a job interview and I had to take a drug test, It was positive on one and negative on the other one. I take Levothyroxin 100MCG, Triamt/HCTZ 75-50MG, Ranitide 150MG and Belladonna Alkaloids with Phenobarbital. would any of these drugs make my urine test postive?


AskDocWeb: Phenobarbital contains barbiturates that would show up on a urine drug test.

Failed drug test
Date: 5/3/2012
I pulled a muscle today at work and I had to take a urine test I tested insufficient for thc I don’t smoke pot and i’m not around pot at all. I was around pot one time 4 months ago didn’t smoke though I took three aleve. I think they were two hundred milligrams a piece at 230. I failed my test at 5 oclock they are going to send it to a lab will I pass?


AskDocWeb: If the lab they send it to is for a GC/MS confirmation test and you have been honest then you will most likely pass. There is always a chance of human error when doing a test but that is so small that we would not be concerned about it.

I tested postive for pot.An i have not smoke pot for a long time. This was a DHS urine test. What could of caused a postive result? The only thing i have smoked is k2.


AskDocWeb: On a State level, several States have made the sale and/or possession of the synthetic form of marijuana such as “K2? illegal.
On March 1, 2011, the U.S. Drug Enforcement Administration invoked its “emergency scheduling authority” to make most “legal high” products illegal. The DEA action applies to five of these drugs: JWH-018, JWH-073, JWH-200, CP-47,497, and cannabicyclohexanol. The drugs are now on the DEA’s Schedule I, meaning they have no accepted medical use and high potential for abuse.
