Every day hundreds of people fall victim to drink-spiking, the tipping of an incapacitating substance into someone's drink glass or bottle and in many cases there usually is a sinister sexual motive. How do I perform this test? The test takes only seconds to perform and is as easy as placing a couple of drops of the drink in question onto the active test spots on the test cards (either by using a swizzle stick or your finger). Once applied to the test card rub gently and wait until it dries. If either circle changes to a darker blue colour, it means that your drink is contaminated. It would be helpful to interpret the test results in a good light source in order to interpret the colour variations better.
