Yes! Since Meth is made from it, if you take enough of it, you can eventually test positive for methampethamines. You can also test positive for meth if you take a lot of Sudafed and other cold medicines.
Depending on what method the lab is is using to test your urine, you could test positive for amphetamines if you take pseudoephedrine (Sudafed)
Hydrocodone is an Opiate based painkiller, so no, It cannot test positive for Amphetamines - but it will on the other hand, Test positive for Opiates (Heroin, Morphine, Oxycodone ect.)

All of them
My pharmacist told me dextroamphetamines do not cause a positive result for methamphetamines as they are not the same
Ephedrine can show a false positive for amphetamines on a drug test.
