Pills only stay in your system for 3-5 days
If its not to late.... Time will depend on stuff like .. Type of test (urine, saliva, hair, lab or rapid home test, etc), how much and often you take, body type and metabolism, etc.. Trazodone may show positive for benzodiazepines (detection period in urine is 4-10 days to 4-6 weeks/ 90 days for standard hair drug test). Best you can do its to order online home test kit with panel for benzodiazepines and check your self.
