If one needs to pass a drug test, the first thing is to determine the technology being used. This may not be enough as the technology has emulously advanced that most aspects relating to one’s medical condition are held private and unauthorized persons cannot acquire the same information for their selfish interests. In some developed nation like the United States, the United Kingdom among others, testing for the drug is a normal routine for civil servants, and they are usually done on short notices. Of course, there have been rare cases where people have managed to get hold of the blood and urine for the test before they are tested for drugs.
If you happen to be among the lucky one who can access the sample, then it’s easier to pass the test since you can contaminate the samples by introducing salt or any other additive to alter the sample in order to favor you. Alternatively, there are some detoxifying drugs which one can introduce into the body to reduce the effects of the drug being tested on you. A recent study by CFC indicates that nowadays drug abusers or uses rely so much on other drugs to alter their medical composition. Nevertheless, in some situations, drug abuses or users fail to pass the test as they may lack adequate time to inject or introduce another drug to suppress the effects of the other drug.
