Amphetamines Are Psychotropic Drugs That Act On The Neuronal Junctions

Amphetamines are psychotropic drugs that act on the neuronal junctions increasing the levels of dopamine and thereby produce excitement. It can be taken orally either in the form of smoke or sniffed. On repeated usage of amphetamines, tolerance develops and it leads to the tendency of increasing the dose.

Amphetamines produce psychic dependence but without any abstinence syndrome. But on continuous use may lead to sever hyper excitement, hallucinations and psychoses. There is also hyperpyrexia and hypertension, which can occasionally precipitate a cerebral or a sub-arachnoid hemorrhage and a risk of cardiac arrhythmias. Drug test for amphetamines on a regular basis can identify those who are addicted at an earlier stage.

Apart from these clinical symptoms and history of drug abuse, the best sensitive and most accurate method is the testing for the drug in urine. Urine is the best sample that can be used for the detection of amphetamine and methamphetamine.

Immunoassays are the techniques employed for the detection drugs in urine. This is the initial screening procedure. Samples that test positive are further sent for confirmatory testing using gas chromatography or mass spectrometry.

Amphetamines can be detected in urine from 7 to 32 hours. This huge variation depends on the pH of the urine. But the detection period depends mainly on the amount of drug consumed, the fluid consumption after the intake of drug, the amount of drug that has been excreted and the pH of the urine.

The most important factor that needs to be noted here is that the drug can not be detected even after consumption if it does not reach the cut off value.

10 panel drug screen, 12 drug panel screen, 5 panel drug screen and single panel tests are available to test for amphetamines. It is important to perform these tests on a periodic basis to detect them in the earlier stages of addiction.
