We will show you how long methamphetamines stay in your system and are detectable on saliva, hair and urine drug tests.
A saliva drug test has the shortest detection period with meth showing up within 5-10 minutes of use. Meth can still show positive for about 3 days on a saliva test.
The hair drug test has the longest detection period with meth showing up about 7 days after the last use. Most hair drug tests will show a 90 day history of meth use based on a hair sample 1 1/2" long. Each 1/2" of hair holds about a 30 day history of drug use.
The most common test is a urine drug test and meth will show up on a urine drug screen within 2-5 hours of use. Meth can remain detectable in urine for about 3-5 days. A Methamphetamine urine drug screen can show false positives with some over the counter medications like Vicks Inhaler or Zantac.
Any non- negative result should be sent to a lab for confirmation.
