Nordazepam is the active metabolite of diazepam, chlordiazepoxide, clorazepate, prazepam, pinazepam, and medazepam. It is the reason all these substances are considered long-acting. Nordazepam has an extremely long half-life (up to 200 hrs) and it has nice muscle relaxant effects, nice anxiolytic effects, and good anticonvulsant action. But it's not a heavy sedative-hypnotic or amnesic. Not many find it recreational, some people do, however. It has all the classical benzodiazepine effects, it's just a long-acting lightweight.
