It is also difficult to establish how often GHB is used to facilitate rape as it is difficult to detect in a urine sample after a day, and many victims may only recall the rape some time after its occurrence; however, a 2006 study suggested that there was "no evidence to suggest widespread date rape drug use" in the UK, and that less than 2% of cases involved GHB, while 17% involved cocaine, and a survey in the Netherlands published in 2010 found that the proportion of drug-related rape where GHB was used appeared to be greatly overestimated by the media.
