How many days does meth stay in your system?

Not Medical Advice: It’s almost impossible to know the exact time meth stays in your system. Detection timetable depends on many factors including metabolism, age, weight, hydration level, physical activity and health conditions and the amount the user has consumed.

Meth can be detectable for a shorter time with some tests, but can still show up for 3 months in other tests. Following oral administration, methamphetamine concentrations are seen in 2.6-3.6 hours and the mean elimination half-life is 10.1 hours (range 6.4-15 hours).

Here is an estimated range of times during which meth can be detected by different testing methods:

  • Urine Test: 1-4 days
  • Blood Test: 1-3 days
  • Saliva Test: 1-4 days
  • Hair: up to 90 days

The organization behind the ‘Faces of Meth’ campaign has released a video that uses mug shots to show how a person’s face can change so dramatically in just a few years. See them at New York Daily News.
