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: Chelsea, Massachusetts

Chelsea is a city in Suffolk County, Massachusetts, United States, directly across the Mystic River from the city of Boston. As of 2013, Chelsea had an estimated population of 36,828. It is also the second most densely populated city in Massachusetts behind Somerville. With a total area of just 2.21 square miles, Chelsea is the smallest city in Massachusetts in terms of total area.

Chelsea is a diverse, working-class community that contains a high level of industrial activity. It is one of only three Massachusetts cities in which the majority of the population identifies as Hispanic or Latino, alongside Lawrence and Holyoke. After flirting with bankruptcy in the 1990s, the once-struggling industrial city has reversed a prolonged decline and in recent years has enjoyed sustained economic growth. Thanks to its relative affordability and close proximity to Boston, Chelsea has added more than 1,200 homes since 2005, mostly loft-style apartments and condominiums suitable for small families or young professionals. There has also been significant office, retail and restaurant development throughout the city.

The area of Chelsea was first called Winnisimmet (meaning "good spring nearby") by the Massachusett tribe, which once lived there. It was settled in 1624 by Samuel Maverick, whose palisaded trading post is considered the first permanent settlement by Boston Harbor. In 1635, Maverick sold all of Winnisimmet, except for his house and farm, to Richard Bellingham. The community remained part of Boston until it was set off and incorporated in 1739, when it was named after Chelsea, a neighborhood in London, England.
