Detailed Answer:
Hi,

Thanks for writing back to us.

Yes it is possible that without taking methamphetamine urine test can come positive for the same. It is due to some other drug which show s there presence falsely for methamphetamine. it is called false positive results.

In your case drug trazodone is responsible for the false positive result of methamphatemine.
The trazodone metabolite meta-chlorophenylpiperazine can cause false-positive urine amphetamine immunoassay results.

You can find the evidence with below pubmed article which can help in any legal matter and prove that you are not actually taking any amphetamine.
