A member asked:

My friend ask,how long does it take methamphetamine drugs remains in his body.

A doctor has provided 1 answer

2-4 days: Methamphetamine itself is rapidly metabolized and lasts only a few hours in the bloodstream and the brain, but its metabolites hang around much longer and can be detected in urine for up to 4-5 days in heavy users. Hair testing can detect use several months back.
