Dependent users may get withdrawal symptoms ranging from restlessness and insomnia to convulsions and death.
When users become psychologically dependent, they feel as if they need the drug to function, although physical dependence does not necessarily occur, particularly with a short course of use.
Lorazepam is one such pharmacological agent that can cause anterograde amnesia.
Intensive care unit patients who receive higher doses over longer periods, typically via IV drip, are more likely to experience such side effects.
Others take sedatives recreationally to relax and forget their worries.
