After Mexican independence from Spain in the early 19th century, Spanish colonists were given land grants, one of which was Rancho El Sobrante, deeded to Juan Jose and Víctor Castro in 1841. The grant's boundaries were unusually complicated, as they were to be determined by the boundaries of the surrounding grants: San Antonio, San Pablo, El Pinole, Boca de la Cañada del Pinole, Acalanes, and La Laguna de los Palos Colorados. In this sense, the rancho was el sobrante, the remaining area. Legal disputes concerning the borders and the claims of squatters continued for four decades, with much of the land sold to pay court and attorney costs. Victor Castro was left with 549 acres (2.22 km2) of the original grant. He built an adobe dwelling in what is now El Cerrito, and became one of the first members of the Board of Supervisors of Contra Costa County. Castro died at the age of 90 in 1897. Some of his descendants still live in the area of Castro Ranch Road.

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

After Mexican independence from Spain in the early 19th century, Spanish colonists were given land grants, one of which was Rancho El Sobrante, deeded to Juan Jose and Víctor Castro in 1841. The grant's boundaries were unusually complicated, as they were to be determined by the boundaries of the surrounding grants: San Antonio, San Pablo, El Pinole, Boca de la Cañada del Pinole, Acalanes, and La Laguna de los Palos Colorados. In this sense, the rancho was el sobrante, the remaining area. Legal disputes concerning the borders and the claims of squatters continued for four decades, with much of the land sold to pay court and attorney costs. Victor Castro was left with 549 acres (2.22 km2) of the original grant. He built an adobe dwelling in what is now El Cerrito, and became one of the first members of the Board of Supervisors of Contra Costa County. Castro died at the age of 90 in 1897. Some of his descendants still live in the area of Castro Ranch Road.
