Frankly speaking, if it is possible to avoid passing a drug test, try to do it, however in the situation when passing a drug test is inevitably, read the following information on how to do it.
It will be better for you not to use such methods as disguising the urine sample when a person’s sample is replaced with specially created commercial samples which are used to throw off testing apparatus from detecting drugs metabolites presence, because modern testing can easily detect the artificial samples such as, for example Terminator Gold or Golden Seal and many others.
Actually, diluting the sample is a rather good way out. As for dilution, it is such a process when the amount of drug metabolites in the urine sample is reduced with the help of adding water or other fluid into the sample. This method allows both lessening the level of creatinine - the substance which is used by muscles and produces creatinine (a waste product) and specific gravity.
However, call your attention to the fact that drug testing laboratories regularly check samples to discover dilution. That’s why if you want to use the method of diluting the sample, it will be better for you to use warm water that has the same temperature as your urine sample. And one more interesting detail, when a person passes a drug test he/she is usually put in a special room where there is no sink, and toilet water is colored.
Very often people use so called flushing or internal dilution, the method when a person drinks plenty of water to reduce the amount of drug metabolites in the urine. But you should know that it can be detected either.
