Amphetamine is a Schedule II controlled substance available by prescription but is also available on the illicit market. Amphetamines are a class of potent sympathomimetic that in higher doses lead to enhanced stimulation of the central nervous system and induce euphoria, alertness, reduced appetite, and a sense of increased energy and power.
The effects of amphetamines generally last 2-4 hours following use, and the drug has a half-life of 4-24 hours in the body. About 30% of amphetamines are excreted in the urine in unchanged form, with the remainder as hydroxylated and deaminated derivatives.
The drug testing kits below yield a positive result when Amphetamine metabolites in urine exceed 1,000 ng/mL. This is the suggested screening cut-off for positive specimens set by the Substance Abuse and Mental Health Services Administration (SAMHSA, USA).
