Date-rape drink spiking 'an urban legend' - Telegraph
Initial research in England and Australia at least suggests it's very, very rare and that when people think they have been slipped something they were probably just blackout drunk.
A study of more than 200 students revealed many wrongly blamed the effects of a "bad night out" on date-rape drugs, when they had just drunk excessively.
Many are in "active denial" that drinking large amounts of alcohol can leave them "incoherent and incapacitated", the Kent University researchers concluded.
Young women's fears about date-rape drugs are so ingrained that students mistakenly think it is a more important factor in sexual assault than being drunk, taking drugs or walking alone at night.
The study, published in the British Journal of Criminology, found three-quarters of students identified drink spiking as an important risk – more than alcohol or drugs.
More than half said they knew someone whose drink had been spiked.
But despite popular beliefs, police have found no evidence that rape victims are commonly drugged with such substances, the researchers said.
