I was wondering if modern drug tests can tell the difference between 20mg and 10mg mixed amphetamine salt prescriptions? I know they can use that chiral separation technique to get a lot of info on where the drug came from but just how specific is it? Can it tell between different strengths and brand names?
Sorry for the dumb question but I was curious and did some searching that didn't turn up anything. Thanks for any responses, I am new to the forum and loving all this great info!
