How Long Does Meth Stay in Your System?
Methamphetamine is a powerful stimulant that affects the central nervous system. Because meth can significantly impact mood, sleep, appetite, and impulse control, many people search for how long it remains detectable, especially when facing withdrawal, health concerns, or drug testing.
In many cases, meth can be detected in urine for up to 5 to 7 days, though detection windows vary based on frequency of use, metabolism, dosage, and overall health.

Meth Detection Times by Test Type
| Test Type | Detection Window |
|---|---|
| Urine | Up to 5–7 days |
| Blood | 1–3 days |
| Saliva | 1–4 days |
| Hair | Up to 90 days |
Chronic or heavy meth use can extend detection time.
Meth Half-Life
The half-life of methamphetamine averages 10–12 hours, meaning it takes approximately that amount of time for half the drug to be eliminated. However, metabolites may remain detectable longer.
Meth Withdrawal
Meth withdrawal typically begins within 12–24 hours after the last use. Symptoms peak within the first week and gradually improve.
Common Meth Withdrawal Symptoms
- Fatigue
- Depression
- Anxiety
- Insomnia or excessive sleep
- Increased appetite
- Cravings
- Irritability
- Psychosis (in some cases)
Some individuals experience Post-Acute Withdrawal Syndrome (PAWS), where mood instability and cravings persist for weeks or months.
