Methamphetamine (meth) typically stays in the blood for about 1 to 3 days after use. Its half-life in the body is around 10-12 hours, meaning it takes that long for half of the drug to be eliminated. However, the exact duration meth remains detectable in the blood can vary depending on factors such as dosage, frequency of use, metabolism, and overall health. Blood tests can usually detect meth within 1-2 hours after ingestion and up to 3 days after the last dose. In summary:
- Meth detectable in blood: 1 to 3 days
- Half-life of meth: about 10-12 hours
- Detection windows depend on individual factors and usage patterns.
