Can large amounts of Valium stay in your system for over 6 weeks?

Yes, large amounts of Valium (diazepam) can remain in your system for over six weeks. Diazepam has a long half-life, and its metabolites can accumulate in the body, especially with prolonged use or higher doses. Factors such as individual metabolism, age, liver function, and frequency of use can influence how long it stays detectable in urine, blood, or other testing methods. However, for most people, it typically clears from the system within a few days to a few weeks.
