HOW LONG does it take to get methamphetamine out of your system?

90 days
It stays in your system for 3 to 4 days. And if I were you just don't touch the stuff, it will kill you.

Depending on the severity of use, and method used, it can range from 24 hours to over 4 days for very heavy & long-time users. Average is 72 hours for a urine test.

It takes 12 hours for the body to remove 50% of the drug from their system; it takes 2 to 10 days to be totally clear.
