date-rape drugs to be the reason for a 'bad night out'

Spiking of drinks with date-rape drugs may just be an urban legend, say scientists, who claim that women who booze themselves into a stupor 
generally use it as an excuse.

In a study of above 200 students from universities in London and southeast England, it was observed that most girls claimed date-rape drugs to be the reason for a 'bad night out' when they had just drunk excessively.
The Kent University researchers suggested that a lot of young women also live in 'active denial' of the fact that consumption of large amounts of alcohol can leave them 'incoherent and incapacitated.'

The researchers pointed out that even though more than half of the girls said they knew someone whose drink had been spiked, yet the police generally did not find that rape victims had been drugged with substances like Rohypnol and GHB.

Nick Ross, chair of the Jill Dando Institute of Crime Science said, "There is no evidence of widespread use of hypnotics in sexual assault, let alone Rohypnol, despite many attempts to prove the contrary."
