This test detects the presence of amphetamine in your urine. Amphetamine is a central nervous system stimulant, and it can show up in your urine long after you've taken it. This group of drugs also includes methamphetamine, or "meth."
Amphetamine is a commonly used illicit drug that overstimulates the central nervous system and makes users feel unusually alert, energetic, and productive. Stimulants like amphetamine and methamphetamine can also cause euphoria, overwhelming agitation, delusions, and hallucinations. Feelings of aggression and paranoia can make people more prone to violence. Abusing these drugs can also cause other serious health problems, including stroke, heart disease, convulsions, and severe tooth decay.
Amphetamine also has medical uses. Doctors sometimes prescribe the drug in small doses for patients with attention-deficit disorder and attention-deficit/hyperactivity disorder. In addition, doctors sometimes use the drug to treat depression and narcolepsy, a sleep disorder marked by falling into a sudden deep sleep in inappropriate places or situations
