Here are some general guidelines for how long methamphetamine can stay in the body:

Blood: Methamphetamine can be detected in the blood for up to 1-3 days after use.

Urine: Methamphetamine can be detected in urine for up to 3-7 days after use, but may be detectable for up to a month in chronic or heavy users.
