Drug Name : Amphetamines/ Bennies/ Ice
Indication :Amphetamine and methamphetamine are major drugs of abuse.
Physiology :Amphetamines are stimulants that tend to increase alertness and physical activity. Some drivers use amphetamines to counteract the drowsiness or ‘down feeling’ caused by sleeping pills or alcohol. Abusers also sniff the crystals, make a solution and inject it, or smoke the form known as “ice”. Can be detected in urine 3 hours after use. Amphetamines increase the heart and breathing rate and also blood pressure, dilate the pupils, and decrease appetite.
Normal Values :Negative (less than cutoff)
Critical Values :Screen – 1000 ng/mL; Confirmation: 500 ng/mL.
Test Method :Radio Immunoassay (RIA), Enzyme Immunoassay (EIA), Gas Chromatography (GC), Thin Layer Chromatography (TLC), High Performance Liquid Chromatography (HPLC)
Side effects :The patient can feel dry mouth, sweating, headache, blurred vision, dizziness, sleeplessness, and anxiety. Extremely high doses can cause people to flush or become pale, and they can cause a rapid or irregular heartbeat, tremors, loss of coordination, and even physical collapse. People who use a large dose over a long period of time may develop an amphetamine psychosis: seeing, hearing, and feeling things that do not exist, having irritating thoughts or beliefs and feelings that people are out to get them.
