Can urinalysis differentiate Methanphetamine from Dextroamphetamine?
Re: Urinalysis Ability to Differtate Methamphetamine from Dextroamphetamine(Dexidrine) I have been asked to take random 1 month urine testing. I have a prescription for Dexidrine-60mg/day, for my ADD. However, I do not take these. I do however use about 200mg METHamphetamine daily, which is NOT pharmaceutical. I have informed the party requesting the urinalysis that I am taking Dexidrine. I realize the initial urinalysis test will not be able to tell the difference, but my Question is: Are they be able to do further testing with that that urine to determine if it is Dextroamphetamine vs. my illegal Methamphetamine consumption.
