Probe detects 'date rape' drugs

According to a recent report, scientists have developed a gadget that will detect the presence of "date rape" drugs like GHB in your drink:

The drugs are often colourless, odourless and difficult to taste when mixed with drink. Modern detection techniques including conventional methods such as test strips are far from perfect and are prone to false positives, as well.

But the device developed by scientists at the London South Bank University claims to overcome all these problems.

The device has a probe, which when dipped into a drink, passes a current through it and records the characteristics of the resulting signal. It then compares this signature with a library of known drug signatures stored in its memory to find a possible match, reports New Scientist.

It would be nice if the device could be tuned to detect the presence of too much bitters in my Manhattans, or too much vermouth in my martinis, but I guess that's taking things a little too far.
