Short for
benzodiazepine.
The benzodiazepines are a class of drugs with hypnotic, anxiolytic, anticonvulsant,
amnestic and muscle relaxant properties.
Benzodiazepines are often used for short-term relief of severe, disabling anxiety or insomnia. Long-term use can be problematic due to the development of tolerance and dependency.
They began to be widely prescribed for stress-related ailments in the 1960s and 1970s.
Often used by people doing LSD if they have to go to sleep fast during a
bad trip.
