Amphetamines are usually detectable in the body for a few days. In urine tests, they can show up for 1–3 days after use. In blood tests, they may be detectable for about 12–24 hours, and in hair tests, they can show up for several months. Frequency of use, dosage, and your metabolism affect how long they remain detectable.
