New test detects drug use from a single fingerprint

Summary:

In the University of Surrey, a team of researchers from the Dutch Forensic Institute have demonstrated a new non-invasive test that can detect cocaine through a single fingerprint. For the first time, this new method of fingerprinting can determine whether the cocaine was ingested, rather than just touched.

Also have used this method for other parts of body, for example the saliva or others.

In this process the scientists use analytical chemistry technique known as mass spectrometry. 

 Opinion:

 I think that this is a very good idea because we could find the people who take a drug and we can give them a fine.

Also, when we perform this technique we could avoid the people take drugs and the world would be safe.
