Drug testing timelines show the length of period a specific drug stays in your system. These timelines vary according to the type of test you are using.  Generally, benzodiazepine presence is measured in blood, urine, saliva, and hair. Drug detection times will prove either positive or negative presence of benzodiazepine traces in your hair, urine, or saliva. Different methods of drug testing have variable windows of detection. So, how long benzodiazepines stay in your blood, urine, and breath can vary.
