Summary TheDrug.Wiki Erowid TripSit PsychonautWiki

Lorazepam is a classical benzodiazepine known for strong sedative and amnesic properties. It should only be used for short-term relief due to rapid tolerance and severe withdrawal risks. Never discontinue abruptly after regular use; tapering over weeks is essential.
