What is the detection window for methamphetamine?

• A. 2-3 days
• B. 2 days - 3 weeks
• C. 1-2 days
• D. 1 month

Answer: (A)

In drug testing, the detection window is the time after use during which a substance can still be found in a specimen. For methamphetamine in a routine urine screen, most people test positive about 2 to 3 days after use. This reflects how meth and its metabolites are cleared into urine within a few days; heavy or frequent use can extend the window, but the common, expected period is a couple of days. The other options don't fit typical urine testing: 1-2 days is usually too short for a single use, while 2 days to 3 weeks mixes an short and longer period that isn’t consistent with standard screens; 1 month is not typical for urine testing (it would apply only to other matrices like hair). So the 2-3 day window best matches standard methamphetamine detection in urine.
