What is a Drug Test?

A drug test is a technical analysis of a biological specimen, for example urine, hair, blood, breath, sweat, and/or oral fluid/saliva-to determine the presence or absence of specified parent drugs or their metabolites. Major applications of drug testing include detection of the presence of performance enhancing steroids in sport, employers and parole/probation officers screening for drugs prohibited by law and police officers testing for the presence and concentration of alcohol (ethanol) in the blood commonly referred to as BAC (blood alcohol content). BAC tests are typically administered via a breathalyzer while urinalysis is used for the vast majority of drug testing in sports and the workplace. Numerous other methods with varying degrees of accuracy, sensitivity (detection threshold/cutoff), and detection periods exist. A drug test may also refer to a test that provides quantitative chemical analysis of an illegal drug, typically intended to help with responsible drug use.

Does passive smoke inhalation cause a false positive for marijuana?

"Passive" smoke inhalation from being in a room with people smoking marijuana is not considered valid, as the cut-off concentrations for lab analysis are set well above that which might occur for passive inhalation.

Other abnormalities in the urine screen may indicate that results may be a false negative or that there was deliberate adulteration of the sample. For example:

  • a low creatinine lab value can indicate that a urine sample was tampered with; either the subject diluted their urine by consuming excessive water just prior to testing, or water was added to the urine sample.
  • creatinine levels are often used in conjunction with specific gravity to determine if samples have been diluted. To help avoid this problem, the testing lab may color the water in their toilet blue to prevent the sample being diluted with water from the toilet.
  • subjects may also attempt to add certain enzymes to the urine sample to affect stability, but this often changes the pH, which is also tested.

How long do drugs stay in your system?

The window of detection or often times referred to as look back period of a drug test depend on several factors. Some of the factors impacting how long a drug will stay in your system are:

  • The amount of the drug taken
  • The frequency of the drug taken

Local Area Info: Centreville, Virginia

Centreville is a census-designated place (CDP) in Fairfax County, Virginia, United States and a suburb of Washington, D.C. The population was 71,135 at the 2010 census. Centreville is approximately 20 miles (32 km) west of Washington, DC.

Beginning in the 1760s, the area was known as Newgate due to the popularity of the conveniently-located Newgate tavern. William Carr Lane operated the tavern and was co-proprietor of a nearby store with James Lane, Jr. The Lanes sold convicted servants, which may explain why the tavern had the same name as a London prison. The small stream that passed near the tavern was named the River Thames, another London association. Another reason for it being named Newgate, was the fact that it was a "new gate" to the western territories.

The town of Centerville (shortly thereafter spelled Centreville) was established in 1792 on the turnpike road at the village of Newgate by the Virginia General Assembly in response to petitions by local landowners. The petitioners reasoned that a town on the turnpike road leading from the Northwest Territory and centrally located to Alexandria, Colchester, Dumfries, Middleburg, George Town (later Georgetown), Fauquier Court House (later Warrenton), and Leesburg would be convenient. The town acquired its name due to its central location. James Hardage Lane, one of the landowners, conceived the idea of the town as a way to provide financial support to his widow and their children. At the town's inception, it was within the boundary of Loudoun County, Virginia, and became part of Fairfax County, Virginia in 1798 when the boundary between the two counties shifted.
