Rohypnol has been labelled by the media as the ‘date rape’ drug, flunitrazepam is notoriously known to cause a very strong sleepy effect and loss of memory, making certain users very vulnerable. Another common effect with high doses (as little as 2mgs), is a complete unawareness of setting and some users have found themselves arrested for offences such as theft/shoplifting and reported no recollection of the events leading to their arrest. Flunitrazepam is a fairly long-acting benzodiazepine, and has hypnotic, sedative and muscle relaxing effects. It is also used as the last resort for the treatment of insomnia, only if other drugs are not effective. It is not usually prescribed in the medium long-term.
