Drug testing usually involves a toxicology screen which would be necessary to check for certain kinds of drugs that are deemed illegal as well as certain legal ones. There could be a variety of reasons why this is done, such as to check for overuse or abuse of legal drugs when a patient is brought in unconscious and the doctors need to know this. It could also be that there are legal limits, such as in the case of alcohol use. There are tests to check for amphetamines, which are known to be central nervous stimulants. This drug is valued for its tendency to produce higher energy levels and a sense of alertness. It also tends to curb hunger as well as increase wakefulness. Amphetamines are also prized for the sensation of well being that they offer. The problem is that you tend to take large doses and eventually, like any other drug, amphetamine usage could lead to dependence and a rise in tolerance levels.
There are different prescription medications which are known to contain amphetamines. As far as prescription medication goes, with regards to amphetamines, one of the most common pills would be regular diet pills which are available on prescription. There are a number of other legal drugs, which are otherwise standard, which may have amphetamines as an active ingredient. Furthermore, the results of an amphetamine test could be false positive on account of other prescription drugs which have, as their active ingredients, a number of other drugs. This is because they could possibly be metabolized into amphetamines, clouding test result. Examples of such ingredients include ethyl amphetamine and mefenorex so you would need to clear your current medication usage with your doctor before such an amphetamine test.
Drug toxicology screens are used in diverse ways and there are a number of tests that are used. Methodology also differs and samples needed could differ since such screens could utilize blood and urine in addition to other sample sources, such as stomach contents. Certain drugs would naturally show up in some samples, such as urine samples, more than others. From blood alcohol level testing which needs a blood sample to drug testing in athletes which necessitates a urine one, there are different kinds of drug tests. These days, companies are even offering home testing kits, such as in the case of amphetamines, so as to offer screening for drugs.
