Researchers at the University of British Columbia have developed a discrete new tool to guard against drink spiking and date rape. It's a small stir stick, dubbed 'Spikeless,' that can detect common drugs secretly slipped into drinks such as gamma-hydroxybutyric acid (GHB) and ketamine, giving results within seconds. The UBC-developed stir sticks have tips coated in a chemical that changes color when it detects a harmful drug in a drink. It works on both alcoholic and non-alcoholic beverages without contaminating the drink. Ex-CIA officer Brian Jeffrey Raymond (below) spiked the drinks of his 28 sexual abuse victims in several countries over 14 years before finally being caught in Mexico.
