It is a long-acting prescription medication used to treat anxiety disorders, muscle spasms, seizures, insomnia, and alcohol withdrawal symptoms. It is available as tablets, oral solution and injection. 
Continued use of Valium for a period of longer than 4-6 weeks can easily lead to tolerance, dependence, and possible addiction. This is why the medication is listed as a Schedule IV under the Controlled Substance Act. 
According to the 2017 National Survey on Drug Use and Health, there were more than 7 million Americans using diazepam in the past year. Of them, most were adults. Still, around 131,000 people who use Valium in the U.S. were adolescents and 650,000 were Americans between the ages 18-25.

Why Drug Test?
Diazepam is a tranquilizer that can cause sleepiness, drowsiness, confusion, and memory loss. Employers may order a drug test in order to identify the reasons for work impairment. In other cases, a court may order a drug test for legal reasons.
Additionally, there may be medical reasons for a drug text. For example, emergency rooms drug test in cases of injury or overdose. Or, your prescribing doctor may ask you for drug testing as part of your treatment. Finally, people in rehab are regularly tested for the presence of psychoactive drugs like diazepam. Knowing more about drug testing and how long Valium will remain in your system and is important, whatever the reasons.
A drug detection window is the period of time during which a drug screen can detect the presence of a drug or its metabolites in your urine, hair, saliva, or blood. The half-life of Valium is fairly long. On average, it can take 20 hours or even more for just half of the medication to be eliminated from your system. For chronic Valium users, diazepam can be detected in urine for 4-6 weeks even after you stop taking it.
However, drug detection windows are variable. We might even say that drug detection windows vary by person. This is because detection and metabolism depends on several individual factors, including the type of test used. Additionally, some people metabolize drugs relatively faster than other people.
There are several drug tests used to detect the presence of Valium in the body. These tests use different markers to detect the presence of diazepam in body fluids such as urine, saliva, hair, and blood.
Urine: A urine drug test will detect diazepam for up to 10 days after the last use.
Saliva: Valium is detectable on oral fluid tests 3 days after quitting.
Blood: The detection period for a blood tests is about 2 days.
Hair: Valium can be detected up to 90 days in hair follicle drug test.
IMORTANT: Diazepam detection times in urine, blood, hair, and saliva are in average and can vary greatly between individuals. You should use this information as a general guide only.

- Diet and use of fluids
- Frequency and length of use
