How long does methamphetamine stay detectable in urine?

Not Medical Advice: While standard Amphetamines are easily detectable for only 1 to 3 days, Methamphetamines can remain in the system, and are detectable in urine tests, for 3 to 5 days. If instead of urine a hair test is used, the drug can be detected for about 90 days. Methamphetamine abuse can cause liver damage, lung damage, and brain damage. Abuse effects can be "long term" and potentially life threatening.
