The Japanese have a new method of detecting drugs
New research suggests that people in Japan have developed a new way of detecting the presence of narcotics.
The researchers at the National Institute of Drug Control and the National Health Insurance Agency used a technique known as superimposed magnification to create three-dimensional images of an organ with a high density of drug molecules.
They were able to detect drugs with a density of about 10 micrograms per gram.
That is about as much as a small piece of gum.
But it is not the first time drug detection has been demonstrated using this technique.
In 2012, Japanese researchers created a similar 3D image of an HIV-positive kidney, but it did not detect the drug it was looking for.
