This week's improbable product combo: a lip gloss that comes with a date rape drug testing kit. I am embarrassed to admit that this nutty idea comes from the UK and a company called 2LoveMyLips.

The idea is that you'd be sitting in a bar and as you bend down to adjust the strap on your stiletto, some fiendish cad spikes your Cosmopolitan. But you are ever on the alert and whilst feigning to adjust your lip gloss you cunningly dip a pink taper into your drink that can detect GHB and Ketamine.

Naturally, I take all this to be a gimmick to sell lip gloss. Still, I thought I should check if drink-spiking had reached epidemic proportions whilst I wasn't looking. Robert Hansson, principal chemist at the Forensic Science Laboratory in Australia, conducted a study and concluded it was an "urban myth". Studies in the US turn up a miniscule number of drug spiked drinks (eg: less than half percent).

One thing to bear in mind as you wait for the pink taper to turn blue, is that forensic researchers say that GHB, in particular, is extremely difficult to detect.
