Use

This test is useful for confirming drug exposure involving amphetamines such as amphetamine, methamphetamine, phentermine, pseudoephedrine/ephedrine, methylenedioxyamphetamine (MDA), and methylenedioxymethamphetamine (MDMA). Amphetamines are sympathomimetic amines that stimulate the central nervous system and can suppress appetite. They are used medically for conditions like narcolepsy, attention-deficit disorder, and weight loss. However, due to their stimulating effects, they are often sold illicitly and abused, leading to physiological symptoms such as elevated blood pressure, dilated pupils, and psychosis.
