Arthur T Knackerbracket has found the following story:

In a paper published by The Journal of Analytical Toxicology, a team of experts from the University of Surrey detail how they have built on their world-leading fingerprint drug testing technology, based on high resolution mass spectrometry, which is now able to detect heroin, 6-monoacetylmorphine (6-AM) and other analytes associated with the class A drug.

The team took fingerprints from people seeking treatment at drug rehabilitation clinics who had testified to taking heroin or cocaine during the previous 24 hours. A fingerprint was collected from each finger of the right hand, and the participants were then asked to wash their hands thoroughly with soap and water and then wear nitrile gloves for a period of time before giving another set of fingerprints. This same process was used to collect samples from 50 drug non-users.

The researchers found that the technology was able to identify traces of heroin and 6-AM on drug non-users in every scenario the researchers devised -- whether someone directly touched the drug, handled it and then thoroughly washed their hands, or had come into contact with heroin via shaking someone else's hand.

Surrey's system cross-referenced the information from the drug non-users with the volunteers who were being treated for drug dependency and found that compounds such as morphine, noscapine and acetylcodeine -- alongside heroin and 6-AM -- are essential to distinguishing those who have used the class A drug from those who have not. These analytes were only present in fingerprints from drug users.

    Imagine you are on a cruise ship. The last couple days you get a cough. You didn't bring cough syrup. But on board ship, if you can even find it, it won't be cheap.

    Based on experience, I can state that prescription hydrocodone in small doses is a cough suppressant.
