Is there a distinguishable diffence between D and L amphetamine?
L methamphetamine is found in Vick's Vapor Inhalers and can show a positive result for a methamphetamine drug screening.
D methamphetamine is only found in controlled substances and a positive drug test usually indicates illicit drug use.
HairConfirm Drug Testing Labs can perform tests to distinguish between the types of methamphetamines present in the hair.
