They are opiates so , yes.
No. Methadone is an opiate. Methamphetamine is an amphetamine. Totally different drug classes. But Methadone WILL make you test positive for opiates in general (i.e. morphine, heroin, oxycontin, etc.)
No.
Yes, depending on how high of a methadone dose you are on. Methadone will clog your opioid receptors and make it hard for any other opiate to act in your brain. Usually, any dose higher than 40mg's will block other opiates.
No. Absolutly not.It will come up positive for "Opiates"
it can make you test positive for opiates.
Will flax seeds make you test positive for cocaine
It depends on what kind of pill you are taking. If it is an opiate and has the codeine in it then the opiates would show up. for instance... Oxycontin it wouldn't be the codeine in the drug that would show up it would be the opiate.
Some prescription cough medicines others, i dont know
I don't know the details, but oxycodone is synthesized from thebaine, one of the alkaloids found in opium. The other major alkaloids of opium are morphine and codeine. Buprenorphine is also derived from thebaine. Hydrocodone, hydromorphone, oxymorphone, and dihydrocodeinone are all derived from morphine. Codeine is metabolized into morphine in our livers. BULL SH!T. oxymorphone is made from thebain. all the good opiates and the strongest are made from thebain.
That would be a decision your employer would have to make. It all depends on what their work rules and ethics are.
Suboxone is an opiate. You will fail for opiates, not methamphetamines.
No, Methadone will only show up as methadone because it is synthetic and requires its own test used to detect it.
