Benzodiazepines like Valium can stay in the system a pretty long time. It depends on how much you take and for how long. Also your health, age, weight and metabolic rate play a part.
How long a drug stays in your system depends mainly on it's elimination half life.
For Valium (diazepam) the initial distribution phase is followed by a prolonged terminal elimination phase (half-life up to 48 hours). The terminal elimination half-life of the active metabolite N-desmethyldiazepam is, on average, 100 hours.
So you would actually have to account for the elimination of N-desmethyldiazepam.
It takes 5.5 x elimination half lives (hours) for a medicine to be cleared from your system, therefore Valium or it's active metabolite will be in your system for 550 hours (5.5 x 100hrs) i.e. approximately 23 days.
