Brief Answer:
Yes it is possible

Detailed Answer:
Hello,
Thanks for using Healthcaremagic.

I read your query and understand your concerns.

First of all it is not uncommon to get false positive for meth when you are on Vyvanse. However the presence of positive test on confirmation test (Generally very specific tests) creates doubt for almost all.

However I like to state that there are multiple medications whcih could cause false positive for mth which includes antidepressants such as bupropion and Fluoxetine, Diabetes medications such as Metformin, and others such as pseudoephedrine, labetalol, ritalin.

To contest your case request your PO to send your sample to different laboratory of high caliber which may help you positively.

I hope this helps you.
If you have more questions feel free to write back to me.
Thanks and regards.

Brief Answer:
It is unusual to get false positive at second level of tests

Detailed Answer:
Hello,
Thanks for follow up.

It is unusual to get positive tests on confirmation of tests and difficult to believe as done you them. However false positive tests do happen around the world despite application of highly sensitive tests and contesting your case in right manner is required since you never abused Meth any time in recent past.

I have simply provided a list which is commonly associated with false positive for meth and hopefully it will help you to contest.

I hope this clarifies further.
Thanks and regards.
