During the Civil War, the United States Military Railroad Construction Corps built a railroad siding here on the Orange and Alexandria Railroad in order to supply the Union Army with timber for railroad ties, bridge trusses, and firewood. The siding was named after John Henry Devereux, superintendent of military railroads that terminated in Alexandria. Wood from hundreds of acres was cut and hauled by wood choppers and teamsters, most of whom were escaped slaves, and transported by train to Alexandria. The laborers risked capture by working outside protected Union lines.

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
  • The type of drug taken
  • An individual's body metabolic rate and general health
  • The amount of fluids consumed since ingesting the drug
  • The amount of exercise since ingesting the drug
  • Other genetic variations that would impact an individual's response to a specific drug

Local Area Info: Clifton, Virginia

Incorporated by the General Assembly on March 9, 1902, Clifton is one of only three towns in the county, the other two being Vienna and Herndon. Clifton's history begins pre-colonially, when the area was used as hunting grounds by the local Dogue Native American tribe. A railroad siding was constructed here during the Civil War, and the area became titled as Devereux Station. A nearby neighborhood on the outskirts of the Clifton ZIP code has this name. Development of a village at the siding began in 1868 when a railroad depot, named "Clifton Station", was constructed.

Unlike most areas in Northern Virginia, the land around Clifton is far less built up than nearby areas, especially to its east and southwest. This was out of the worry that overdevelopment near Bull Run and the Occoquan River would be environmentally damaging to the Occoquan Reservoir. Consequently, as development edged near the area in the late 1970s and early 1980s, an ordinance was enacted stating that only one building could be placed on 5-acre (20,000 m2) parcels that have not already been divided. Today, the southern and eastern portions of the area are heavily forested, with single-family homes, while the northern area has become equestrian areas.

Before the arrival of European settlers, the present-day Clifton area was part of the hunting grounds used by Algonquin-speaking members of the Dogue tribe. The Dogue lived in villages and towns along the Potomac River and nearby Occoquan River. They carved bowls out of soapstone found in the area.

During the Civil War, the United States Military Railroad Construction Corps built a railroad siding here on the Orange and Alexandria Railroad in order to supply the Union Army with timber for railroad ties, bridge trusses, and firewood. The siding was named after John Henry Devereux, superintendent of military railroads that terminated in Alexandria. Wood from hundreds of acres was cut and hauled by wood choppers and teamsters, most of whom were escaped slaves, and transported by train to Alexandria. The laborers risked capture by working outside protected Union lines.
