Sip Safe Wristbands
Monash University and a private company R & R have launched a wristband, Sip Safe, which allows you to check for drugs in a drink by putting a drop of your drink on the wristband. If this assist detect drink spiking with illicit drugs then it is a good idea. However, it would not be a good idea to get too complacent.
Research has shown that the majority of people seen in Emergency Departments who have received a toxicology screen for illicit drugs had in fact drunk a very large quantity of alcohol. In one study on 5 people were tested positive for drugs and only one of those had imbibed illicit drugs. The other 4 people were aware of which drugs they had taken. So the wristband is a nice idea but it will not help you detect alcohol added to a drink.
