I have been taking drug tests for 4 years now and I have never failed for methamphetamine. I take Suboxone 12mg/day, Adderall 20mg 2xday, albuterol aerosol as needed, albuterol sulfate as needed, Advair 500mg 2xday. I also take mini thins (over the counter), Robitussin, 5hr energy. I dont understand how I came up positive now though. I have taken these for a while now and nothing has showed up before. I have done everything that CPS has court ordered me to do for my son to come home and he came home a month ago and the case was almost dismissed. This false positive has made my world crumble around me and I need to find out what happened to that test! Please someone help me!
I recently have failed a drug test for methamphetamines. What could have made a false positive?

I wear a drug sweat patch for probation I take dex amphetamine for ADHD. All my patches have showed positive for meth, but I’m not using it.
Ranitidine aka Zantac
I’m in the same boat, an MRO said I failed even with the prescription for adderall, supposedly my D-Isonmer was high but I don’t do meth. What is the explanation of this, I have 7 years of documented negative drug testing results due to my work, So I’m
Asking how did it happen because my life is getting screwed up
I have found according to how much adderall is in my system affects if I test positive for meth. Been going through this for 2 years with DFCS. Tell them it has to go to lab for a gas test to be accurate since you take Adderall
I have had so many false positives it's ridiculous. Now I request that all my screens go to the lab first, it was getting ridiculous. I hope everything works out for you
It's your Adderall you didn't have a false positive it was a true positive but you would not be reported because you have a Rx for it.
It was the Adderall. Sometimes I come up positive for methamphetamines and sometimes I don't... but it was most likely the Adderall.
Afrin nose drops gives off false positive’s every time and research is there for you doctor.
Adderall
Adderall
The Adderall will show up as a false positive for Methamphetamines.
If you have been on all these meds before and you have been tested clean then the only answer is the 95% rule. These tests are only 95% accurate.
Yes, Adderall can and will show up on a basic methamphetamine test. At that point, the lab should proceed to using standardized differentiation tests to figure out the source of the methamphetamine which will narrow it down to Adderall providing you haven't used a methamphetamine within 7 days from testing.
It seems that you also suffer from respiratory conditions and several asthma medications contain Ephedrine, which is derived from a plant but contains alkaloids that can make a Positive in drug screenings.
This plant is a bronchodilator.
Also the Amphetamines will give you a huge Positive in drug screenings.
I would think the Adderall and inhaler might cause a false dirty
Robitussin is one of the meds that can have you test positive
