Detection Times
Drug testing is becoming more and more essential in the present scenario owing to the increasing number of people consuming drugs for beating out stress. Once started as a passive habit, it soon becomes an addiction that costs several million dollars to the government every year. But for the testing of any drug, it is mandatory to know the detection drug time which differs widely between various drugs.
The detection period of drug in system is governed by various factors that are broadly classified as the primary and the secondary factors. The primary factors include the drug intake, rate of metabolism of the drug in the body, and half life of the drug and the route of excretion. Those drugs that have short half lives and rapid rate of metabolism are difficult to detect after some time whereas it is the vice versa for the long acting drugs. The secondary factors include the status of the liver, and other organ systems which act in a cohesive manner to eliminate the drug from the body. The diseased conditions of the liver and kidney alter the metabolism of drug in the body which sways away from the normal standard values.
There is also a lot of difference between the concentrations of different drugs at different sites of the body. The major sites for the accumulation of drugs are urine, blood, saliva, hair follicle and sweat secretions. The concentration of the drug is seen in the blood once the drug finds its way through the vascular system and takes much more time to reach urine which is the time taken for the drug to get metabolized. The detection time saliva drug test is similar to that of blood. It is possible to detect drug in saliva and oral fluid from the ingestion of the drug.
The drug detection in urine and blood is highly reliable as far as the moderate duration of the drug is concerned whereas for long term detection, hair follicle test is more reliable.
The presence of the illegal drugs that are stocked anywhere can be detected by using drug detection dog. They are trained in a similar fashion for detection of drugs as they are trained for the detection of bombs. The same concept of detection by habituation and training applies here too. The dogs are trained using the white towel dusted with the illegal drug that is recorded in the memory of the dog that can be recalled once re-sensitized.
