Many drink-spike testing kits don't work properly and offer little or no protection, according to new research. Many positive results were false, according to scientists from the Centre for Public Health at Liverpool John Moores University. One testing kit only correctly detected a drug in 69% of tests, and this fell to just 37% with spiked beer. False positive results, adds the report, could have major social and commercial implications. People could be suspected incorrectly of being a perpetrator, it explains, while venues could be perceived incorrectly as being places where such behaviour occurs.
