Which "meth???": Methamphetamine is a short-acting drug, but it has longer acting metabolites which are what are measured in urine. After a single dose, it's half-life is about 4 hours, but metabolites can be found for 2-3 days. After regular heavy use, it can be detected for 5-7 days. Methadone (also called meth) lasts for 3-5 days, and in long-term use metabolites can be detected for weeks.

It depends: It depends on your metabolism, but meth is generally detectable in urine for 1-4 days after use. Urine drug tests are the ones most often used. Meth can also stay in your hair for up to 90 days, though. It's an extremely dangerous drug, and best not to use it at all.
