Using a mouth swab is a secondary way people are tested for drugs. The saliva is extracted from the mouth, then tested for any substances within it.
With a testing kit, one or more lines indicates whether a certain type of drug is present. In the case of a multiple-drug array, each drug is represented by a different color. If the line appears, the drug is not detected.
If a line is missing from the array, it is considered a positive result for the presence of that drug. Electronic versions don't require the reading of lines. Instead, the presence or absence of the target drugs is indicated on a clear, electronic readout.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
