If you mean 'spike' as in "adding" it to urine sample, bad idea: It will screw up the test because METHADONE needs to be metabolized through the body first. Now the people testing you might write it off as "irregular" if you are lucky. However, most METH clinics are hip to this and they will f%# with you.
Only methadone will be detected because the methadone urine test is specifically used to detect methadone.
No they do not. they do however, check for levels of methadone and levels of metabolites to prove the methadone was injested. so if you pour methadone in a drink that looks like urine, no metabolites and too much methadone would look suspicious. I assume this is why you asked.
yes, if methadone is specifically tested for. Most of the time methadone is not tested for, but on tests with more panels a test for methadone will be present. Methadone does not show up in the urine as an opiate.
Methadone can stay in the urine 3 to 5 days depending on the rate of metabolism.
Not doing methadone in the first place
Methadone is a synthetic opiate. Detection time in urine- 1-7 days
Typical illicet drug urine tests don't test for methadone since there is a specific test just for methadone to detect it.
Typically, methadone stays in the urine 3 to 5 days depending on the rate of metabolism.
Drug test to check for methadone metabolites in urine
No, Methadone requires its own test and will only show up positive for methadone.
Methadone will only show up as methadone because it requires its own specific test.
Yes, methadone shows up in a drug test
