Introduction to San Marcos

San Marcos is a city in the North County region of San Diego County in the U.S. state of California. As of the 2010 census, the city's population was 83,781. It is the site of California State University San Marcos. The city is bordered by Escondido to the east, Encinitas to the southwest, Carlsbad to the west, and Vista to the northwest. Lake San Marcos is an enclave, or county island, in the southwestern part of the city, within San Marcos' sphere of influence but technically an unincorporated community.

According to historical legends, the San Luis Rey Mission flocks were robbed by a small band of Native Americans in the late 18th century. Fleeing the Spanish troops, the Native Americans escaped to the hills. While pursuing the Native Americans, in 1797 the Spaniards came upon a fertile valley, which was named Los Vallecitos de San Marcos (Little Valleys of Saint Mark) to honor the day of discovery: April 25, St. Mark’s Day. On April 22, 1840, Governor Juan B. Alvarado granted Rancho Vallecitos de San Marcos to his relative, Jose María Alvarado. Jose Alvarado was killed at the Pauma Massacre in 1846, and the land was left to his wife; she then sold the land to Lorenzo Soto. In the late 1850s, Soto sold part of his land to Cave Couts, and his family was soon raising livestock. Although Cave Couts owned the land, Major Gustavus French Merriam from Topeka, Kansas, made the first permanent settlement. Merriam homesteaded 160 acres (0.65 km2) in the north Twin Oaks Valley and began wine and honey production.

After Major Merriam’s settlement, German and Dutch immigrants began moving into the area in the early 1880s. In 1883, a few miles south of the settlement, John H. Barham (for whom the present-day Barham Drive is named) founded the first town in the area, originally situated on the southeast corner of what are now Rancho Santa Fe Road and San Marcos Boulevard. By 1884, the town of Barham had a post office, blacksmith, feed store and weekly newspaper. In 1887, the San Marcos Land Company bought almost all of the San Marcos land formerly owned by the Couts family and promptly divided the land into tracts. Soon the hills began attracting home-seekers.

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 prohibited by law (such as cannabis, cocaine, methamphetamine, and heroin) 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.
