California was claimed as part of the Spanish Empire in 1542, when explorer Juan Rodríguez Cabrillo charted the Californian coast. During this time, California and Baja California were administered together as Province of the California (Spanish: Provincia de las California). For nearly 200 years, the Californias were sparsely populated and largely ignored by the government of the Viceroyalty of New Spain in Mexico City. Only in 1769 was Northern California finally surveyed by Spanish authorities, with the Portolá Expedition.

Selecting the Right Drug Testing Panel

Drug tests are categorized by panels, specifying the number of substances screened: common options include 5-panel, 10-panel, and 12-panel tests. Custom test panels are also available.

Understanding Drug Tests

Drug tests analyze biological samples—such as urine, hair, blood, breath, sweat, or saliva—to detect drug presence or its metabolites. These tests have critical applications, including monitoring performance-enhancing drugs for athletes, legal compliance for employees, and alcohol levels for law enforcement. The widely-used urinalysis and breathalyzers administer the majority of workplace and sports drug testing. Some tests offer a quantitative analysis of illegal drugs to guide safer usage.

Passive Smoke Inhalation and False Marijuana Positives

Passive exposure to marijuana smoke is unlikely to result in false positives as lab analysis cutoffs exceed levels achievable by passive inhalation.

Unexpected results may suggest false negatives or intentional adulteration. For instance:

  • Low creatinine levels may signal that a urine sample was diluted purposely, either through excessive water intake before testing or by adding water directly to the sample.
  • Used alongside specific gravity, creatinine helps assess sample dilution. Test locations might dye toilet water blue to prevent tampering.
  • Attempted enzymes additions to a sample for stability purposes frequently alter its pH, which is also tested.

Drug Detection Period

The detection window for drugs depends on variable factors. These may include:

  • Drug Dosage Amount
  • Frequency of Usage
  • Drug Type
  • Personal Metabolic Rate and Health
  • Fluid Intake After Usage
  • Physical Activity Post-Usage
  • Genetic Variations Affecting Drug Response

Why Opt for Accredited Drug Testing in San Jose, CA?

Local Area Info: San Jose, California

San Jose[A] (/?sæn ho??ze?, -?se?/; Spanish for 'Saint Joseph'; Spanish: [sa? xo?se]), officially the City of San José,[B] is an economic, cultural and political center of Silicon Valley, and the largest city in Northern California (both in population and area). With an estimated 2017 population of 1,035,317, it is the third-most populous city in California (after Los Angeles and San Diego) and the tenth-most populous in United States. Located in the center of the Santa Clara Valley, on the southern shore of San Francisco Bay, San Jose covers an area of 179.97 square miles (466.1 km2). San Jose is the county seat of Santa Clara County, the most affluent county in California and one of the most affluent counties in the United States. San Jose is the most populous city in both the San Francisco Bay Area and the San Jose-San Francisco-Oakland Combined Statistical Area, which contain 7.7 million and 8.7 million people respectively.

San Jose is a global city, notable as a center of innovation, for its affluence, Mediterranean climate, and extremely high cost of living. San Jose's location within the booming high tech industry, as a cultural, political, and economic center has earned the city the nickname "Capital of Silicon Valley". San Jose is one of the wealthiest major cities in the United States and the world, and has the third highest GDP per capita in the world (after Zürich, Switzerland and Oslo, Norway), according to the Brookings Institution. The San Jose Metropolitan Area has the most millionaires and the most billionaires in the United States per capita. With a median home price of $1,085,000, San Jose has the most expensive housing market in the country and the fifth most expensive housing market in the world, according to the 2017 Demographia International Housing Affordability Survey. Major global tech companies including Cisco Systems, eBay, Adobe Systems, PayPal, Brocade, Samsung, Acer, Hewlett Packard Enterprise, and Western Digital maintain their headquarters in San Jose, in the center of Silicon Valley.

Before the arrival of the Spanish, the area around San Jose was inhabited by the Tamien nation of the Ohlone peoples of California. San Jose was founded on November 29, 1777, as the Pueblo de San José de Guadalupe, the first city founded in the Californias. It then became a part of Mexico in 1821 after the Mexican War of Independence. Following the American Conquest of California during the Mexican–American War, the territory was ceded to the United States in 1848. After California achieved statehood two years later, San Jose became the state's first capital. Following World War II, San Jose experienced an economic boom, with a rapid population growth and aggressive annexation of nearby cities and communities carried out in the 1950s and 1960s. The rapid growth of the high-technology and electronics industries further accelerated the transition from an agricultural center to an urbanized metropolitan area. Results of the 1990 U.S. Census indicated that San Jose had officially surpassed San Francisco as the most populous city in Northern California. By the 1990s, San Jose and the rest of Silicon Valley had become the global center for the high tech and internet industries, making it California's fastest-growing economy.
