Coming in the form of a tasteless and odourless pill which is easily ground down into powder, rohypnol has gained notoriety as the 'date rape' drug, after victims have been incapacitated and sexually assaulted after having their drinks spiked. All traces of the drug disappear after 24 hours making prosecution difficult. Please note that rohypnol is not the only drug associated with date rape and there have been cases linked to GHBand other sedative drugs. 
Side effects: The most worrying side effect of rohypnol is that it can easily be administered without the victims knowledge and lengthy sexual assaults can take place with the victim having no memory of events afterwards. In many cases, victims are even unaware that assaults have taken place until their symptoms are recognised or their memory returns. It's a very nasty drug.

Be very wary of accepting opened drinks from strangers or people you don't trust, even if they are only soft drinks. If you feel odd, nauseous or drunk after only a couple of drinks, leave immediately and go to a place of safety. If you are alone or with a stranger, call friends to tell them where you are and/or go to the landlord or manager and explain your situation.
