Detailed Answer:
Hello XXXXXX
Thanks for writing to HCM

Positive test for methamphetamine is due to dexadrine intake.
Dexedrine contains Dextroamphetamine. It is dextro form of amphetamine.
It reaches peak plasma level within 1-2 hr & are rapidly absorbed from the gastrointestinal tract.
Dextromphetamine is eliminated via the kidneys,30–40% of the drug being excreted unchanged at normal urinary pH.
It is usually eliminated within two days of the last oral dose.Apparent half-life and duration of effect increase with repeated use and accumulation of the drug.

So,positive test for methamphetamine is related to dexadrine intake.
